关键词：棒材矫直工艺二辊棒材矫直机矫直力能参数前言金属棒材在轧制、加热、运输等各种加工过程中常常产生不同程度的弯曲、歪扭等塑性变形或内部残余应力；目前冶金市场上对金属棒材的成品精度要求也越来越高，因此轧制矫直设备在工厂中应用越来越普遍，对矫直设备的自动控制要求也越来越高。

在多辊棒材矫直机中，其矫直辊由多个辊子组成；设备在矫直过程中由于其棒材的弯曲程度不同；设备的矫直辊要频繁地进行压下及转角的调整(以下简称调整)。

在国内大多数同类设备中，其调整靠工人依据设备上的标尺，手动控制进行。

对于多辊设备调整起来就非常的麻烦，所需时间较长，为了提高生产率，必须提高设备的自动化程度，辊系的自动调整成为必然趋势。

随着液压控制技术的发展，运用三维扫描检测技术、跟随式检测机构、压力矫直专家系统等专有技术，实现了压力矫直的自动化、智能化，使压力矫直机得以融入连铸或锻造生产线，成为在线设备。

矫直机毕业论文中英文资料外文翻译文献

矫直机论文中英文资料外文翻译文献外文翻译原文：AUTOMATING THE CONTROL OF MODERN EQUIPMENT FOR STRAIGHTENING FLAT-ROLLED PRODUCTS The company Severstal’ completed the successful introduction of new in-line plate-straightening machines (PSMs) on its 2800 and 5000 mills in August 2003 [1, 2, 3]. The main design features of the machines are as follows:●each machine is equipped with hydraulic hold-down mechanisms (toimprove the dynamics and accuracy of the machine adjustments and more reliably maintain a constant gap);●the machines have mechanisms to individually adjust each work roller with theaid of hydraulic cylinders (this broadens the range of straightening regimes that can be realized by providing a measure of control over the change in the curvature of the plate);●each work roller is provided with its own adjustable drive (to eliminate rigidkinematic constraints between the spindles);●the system of rollers of the PSM is enclosed in cassettes (to facilitate repairs andreduce roller replacement costs);●the PSM has a system that can be used to adjust the machine from a nine-rollerstraightening scheme to a five-●roller scheme in which the distance between the rollers is doubled (this is doneto widen the range of plate thick-nesses that the machine can accomodate).Thus, the new straightening machine is a sophisticated multi-function system of mechanisms that includes a wide range of hydraulically and electrically driven components controlled by digital and analog signals. The entire complex of PSM mechanisms can be divided into two functional groups: the main group, which includes the mechanisms that partici-pate directly in the straightening operation (the hold-down mechanisms, the mechanisms that individually adjust the rollers,the mechanisms that adjust the components fordifferent straightening regimes, the mechanism that moves the top roller of the feeder, and the main drive); the auxiliary group (which includes the cassette replacement mechanism, the spindle-lock-ing mechanism, and the equipment that cools the system of rollers). Although the PSM has a large number of mechanisms,the use of modern hydraulic and electric drives has made it possible to almost completely automate the main and auxiliary operations performed on the PSM and the units that operate with it.Described below are the features and the automatic control systems for the most important mechanisms of the plate-straightening machine.The operating regimes of those mechanisms are also discussed.The hydraulic hold-down mechanisms (HHMs) of the sheet-straightening machine function in two main regimes:the adjustment regime;the regime in which the specified positions are maintained.There are certain requirements for the control system and certain efficiency criteria for each regime.In the adjustment regime, the control system for the hydraulic hold-down mechanisms must do the following:●synchronize the movements of the hydraulic cylinders and keep the angulardeeflection within prescribed limits;●maximize speed in adjusting the machine for a new plate size;●maintain a high degree of accuracy in positioning the mechanisms;Fig. 1. Block diagram of the control system of the hydraulic cylinder.The control system has the following requirements when operating in the maintenance regime:●stabilize the coordinates of the top cassette and the top roller of the feeder with ahigh degree of accuracy;●minimize the time needed to return the equipment to the prescribed coordinateswhen deviations occur (such as due to the force exerted by a plate being straightened).Need for synchronization. Experience in operating the plate-straightening machine in plate shop No. 3 at Severstal’ has shown that the most problematic factor in adjusting the machineis the nonuniformity of the forces applied to the hydraulic cylinders. This nonuniformity is due to the asymmetric distribution of the masses of the moving parts of the PSM (in particular, the effect of the weight of the spindle assembly). Displacement of the “hydraulic zero point” relative to the “electrical zero point” in the servo valves is also a contributing factor.The latter reason is more significant, the smaller the volume of the hydraulic cylinder.Thus, the HHM of the top roller of the feeder is the most sensitive to drift of the zero point.There are also other factors that affect the dynamism,simultaneousness,and synchronism of the operation of the hold-down mechanisms:●differentiation of the frictional forces on parts of the hydraulic cylinders due todifferent combinations of deviations in the dimensions of the mated parts, despitethe narrow tolerances;●differences in the “springing” characteristics and the indices characterizing theinertia of the hydraulic supply channels (due to differences in the lengths of thepipes leading from the servo valves to the hydraulic cylinders).Thus, since the PSM is not equipped with devices to mechanically synchronize the operation of the cylinders, the ransmission of signals of the same amplitude to the inputs of the servo valves inevitably results in a speed difference that can seriously damage the mechanisms.To minimize and eliminate the effects of the above-mentioned factors, we developed an algorithm for electrical synchronization of the hold-down mechanisms.The HHM of the top cassette, composed of four hold-down cylinders and four balancing cylinders, is designed to ensuremobile adjustment of the machine to set the required size of straightening gap (in accordance with the thickness of the plate) andmaintain that gap with a specified accuracy in the presence .and absence of a load on the housings from the straightening force.The hydraulic system of the hold-down mechanism is designed in such a way that only one chamber of the hydraulic cylinders is used as the working chamber.The second chamber is always connected to the discharge channel.The top cassette is lowered when the balancing forces are overcome by the hold-down cylinders.The cassette is raised only by the action of the balancing cylinders.This arrangement has made it possible to eliminate gaps in the positioning of the equipment.The HHM of the top roller of the feeder consists of two hydraulic cylinders. Hydraulic fluid is fed into the plunger chamber when the roller is to be lowered and is fed into the rodchamber when it is to be raised.Control Principles. Individual circuits have been provided (Fig.1) to control the hydraulic cylinders of the hold-down mechanisms.The control signal (Xctl) sent to the input of the servo valve is formed by a proportional-integral (PI) controller (to improve the sensitivity of the system, we chose to use valves with “zero” overlap).The signal sent to the input of the controller (the error signal Xerr) is formed as the difference between the control-point signal for position (Xcpt) and the feedback signal (Xf.b).The latter signal is received from the linear displacement gage (G) of the given hydraulic cylinder.The gages of the HHM for the top cassette are built into the balancing hydraulic cylinders (HCs).The cylinders are installed in such a way that their movements can be considered to be equal to the displacements of the corresponding cylinder rods, with allowance for certain coefficients.The gages in the HHM for the top roller of the feeder are incorporated directly into the hold-down cylinders.The integral part of the controller is activated only during the final adjustment stage and during stabilization of the prescribed coordinate.When the displacements exceed a certain threshold value, the functions of the PI controller are taken over by a proportional (P) controller with the transfer function W(s) = k.Thus, Xctl(t) = kXerr(t).When there are significant differences between the displacements of the working rollers,the difference (error)between the control point and the feedback signal from the linear displacement gage reaches values great enough so that the output signal which controls the operation of the servo valve reaches the saturation zone.In this case, further regulation of the displacement rate and,thus synchronization of the movements of the cylinders becomes impossible as long as the error exceeds the value at which Xctl is greater than the boundary value for the saturation zone (Xsat).The limiting error–the largest error for which Xctldoes not reach saturation–is inversely proportional to the gain of the controller k: Xerr< Xsat/ k. Solving the given problem by decreasing k leads to a loss of speed in the adjustment of the PSM and a decrease in control accuracy during the straightening operation.Thus, to keep the control signal from reaching the saturation zone when there are substantial displacements, the system was designed so that the input of the controller is fed not the actual required value (Xrq) but an increment (∆X) of a magnitude such that the condition k∆X < Xsat is satisfied.The control point is increased by the amount ∆X after the position of the cylinder has been changed by the amount corresponding to the increment having the largest lag relative to the cylinder’s direction of motion. The adjustment of the control point is continued until the difference between the required value and the actual position of the mechanism becomes lessthan the increment:Xrq –Xf.b < ∆X.Then the input of the controller is fed the value Xcpt, which is equal to the required adjustment: Xcpt= Xrq.The adjustment is thus completed.Use of the principle of a stepped increase in the control point makes it possible synchronize the movements of the cylinders and set the control point with a high degree of accuracy for almost any ideal repetition factor.Mechanisms for Individual Adjustment of the Working Rollers.The plate-straightening machine is designed so that each working roller can be moved vertically, which is done by means of a hydraulic cylinder acting in concert with a V-belt drive.The cylinders are supplied with power from servo valves operated with proportional control.A linear displacement gage is built into each cylinder to obtain a feedback signal on the position of the roller.Since these gages are actually transmitinginformation on the position of the cylinder rods rather than the working rollers themselves, the following conversion is performed to obtain the rollers’ coordinates:Xrol= kredXf.b,where kred is the gear ratio of the drive;Xf.b is the position of the cylinder rod measured by the linear displacement transducers.Thus, a position feedback circuit is provided to control the position of each working roller. Figure 1 presents a diagram of one of the circuits.The control signals are generated by means of the PI controllere, which has made it possible to achieve a high degree of accuracy in adjusting the system without sacrificing speed.The individual drive of the rollers. The above-described design is based on the use of individual ac drives with motors of different powers fed from frequency converters. Each individual drive offers the following advantages over a group drive:●greater reliability thanks to the absence of additional loads on the components ofthe mechanisms due to differences between the linear velocities of the working rollers and the speed of the plate;●the possibility that the machine could continue to operate if one or even severaldrives malfunction;in this case,the corresponding rollers would be removed from the straightening zone;●the possibility that the linear velocities of the rollers could be individuallycorrected in accordance with the actual speed of the plate;such a correction could be made either as a preliminary measure (on the basis of measured and calculatedvalues) or during the straightening operation (on the basis of the data obtained from the frequency converters, which employ artificial intelligence).The main drive of the straightening machine rotates nine straightening rollers and two housing rollers.This drive must be highly reliable in operation, since the fact that the PSM is installed in the mill line means that sizable production losses can be incurred if the drive fails to work properly even for a short period of time.The requirements that must be satisfied by the drive are determined by the operational and design features of the machine as a whole:●the plate being straightened must create a rigid kinematic coupling between thestraightening rollers, the rollers of the housing, and the adjacent sections of the roller conveyors;●the plate should undergo elongation during the straightening operation as a resultof plastic deformation, with the increments in length being different on each working roller due to the differentiation of the bending radii;this situation leads to a nonuniform increase in the speed of the plate as it moves toward the end of the PSM;●it must be possible to use working rollers of different diameters (this being done,for example, due to nonuniform wear or regrinding);●the loads on the rollers should be differentiated in accordance with the chosenstraightening regime;●reverse straightening should be possible.In light of the above factors and the actual operating regimes of the plate-straightening machine being discussed here, the following requirements can be established for the electric drive:●regulation of speed within broad limits, including startup of the motors underload;●operation in the reverse regime;● a rigid characteristic ω = ƒ(M);●high degree of accuracy in maintaining the prescribed speed;●fully synchronous operation.The element base. The drive of the rollers was built with the use of asynchronous three-phase motors having a short-circuit rotor.The motors were designed by the German company VEM.They can continue to function under severe overloads and are reliable in operation.The motors are controlled by SIMOVERT frequency converters made by the German firm Siemens.Their modular design facilitates maintenance and repair, and the presence of a built-in microprocessor block makes it possible to execute most of the functions involved in controlling the operation of the drive (maintain the prescribed speed with a high degree of stability, recalculate the frequency of rotation in accordance with the actual diameters of the rollers, diagnose the condition o f the drive, control the drive’s operation, and exchange information on the PROFIBUS network).Motors of different powers are used in the system because of the differentiated distribution of the moments between the working ing different motors has made it possible to significantly reduce the cost of the electrical equipment and improve the performance characteristics of the machine as a whole.The machine has three main operating regimes: the working regime (semi-automatic and automatic), the transport regime, and the cassette replacement regime.Figure 2 shows a block diagram of the operations connected with realization of the working regime.In the semi-automatic variant of this regime, the operator controls the PSM from a control panel.In this case, the operator can do the following: choose the straightening regime from a database;correct the chosen regime;adjust the regime manually, which requires that the operator indicate the desired position of the bottom cassette (for five- or nine-roll straightening);adjust the gap between the top and bottom cassettes; set the coordinates for individual adjustment of the working rollers; choose the straightening speed and direction;generate a command to begin adjusting the machine to the specified regime.Fig. 2. Block diagram of the working regime of the PSM.The machine is adjusted to the chosen regime automatically.After the adjustment is completed, a signal is sent to the control panel indicating that the coordinates of the mechanisms have been changed and that the rollers have reached their prescribed working speeds.In the automatic variant of the working regime, the plate-straigthening machine isadjusted on the basis of data sent through a data network from a higher-level system. These data include the following information:●the thickness of the plate being straightened;●the group of steels (information on the properties of the material);●the temperature of the plate at the inlet to the PSM.The PSM is adjusted in several stages:●preliminary adjustment based on the plate thickness and steel group, for cold-rolledplates (t = 20°C);●further adjustment on the basis of data obtained from a pyrometer installed roughly50 m from the PSM;●final adjustment on the basis of data obtained from a pyrometer installed at theentrance to the machine.In the automatic variant, control over the roller conveyors adjacent to the machine is switched over to the control system of the PSM as the next plate approaches the machine.In this case, the plate cannot enter the working zone of the machine until the adjustment is completed.If it is necessary to pass a plate through the machine without straightening it, the machine is changed over to the transport regime.In this case, the top crossarm and the cassette are elevated a prescribed amount and the speed of the rollers is changed so that it is equal to the speed of the adjacent roller conveyors.The cassette replacement regime is used in the event of breakage of a roller or when it is necessary to regrind the working and backup rollers.In this case, the operator can control the operation of the auxiliary mechanisms:the spindle-locking mechanism, the roll-out cart, the mechanism that locks the bottom cassette and the cart in position, and the hydraulic cylinder that moves the cart.The mechanisms are fixed in position by means of noncontact transducers.PSM Control System. Control of the plate-straightening machine required the development of a powerful, high-capacity system that could provide the desired control accuracy in combination with rapid operation.The control system that was created is divided into two levels: the base level, and an upper level.The diagnostic system was created as a separate system.A second controller was also provided, to control the pump station of the PSM.The base level of the control system employs a SIMATIC S7 industrial programmable controller, while the upper level and the diagnostic system were built on the basis of standardcomputers.The computer used for the upper-level system also serves as the control panel for the PSM.Fig. 3. Network structure of the PSM control system.The different elements of the control system are linked by two loops of a PROFIBUS network (Fig.3).The first loop functions as the communications link between the controller, the upper-level computer, the diagnostics station, and the pump-station controller.The second loop links the PSM controller with the functional elements of the system (the frequency converters, linear displacement gages, and remote input/output module).The functions of the control system were divided between the base level and the upper level on the basis of the following principle: the base level was assigned all of the operations that involve receiving data from the sensors installed on the mechanisms, obtaining information from the automated process control system on the plate being straightened, and generating and transmitting control signals for the executive mechanisms (actuators); the upper level was assigned the functions of archiving the control points and monitoring the operation of the control panel.The following specific functions are performed by the base level of the automation system:obtaining the assigned straightening parameters (roller speeds, the coordinates of the top crossarm, and the coordinates of the rollers relative to the crossarm) from the upper-level system;●processing the parameters and sending corresponding control signals to the actuators;●obtaining information from the sensors installed on the mechanisms to determinewhether or not the PSM is properly set and ready for the straightening operation;●obtaining information from the feedback transducers installed on the mechanisms tocalculate the control actions;●analyzing the readings of the sensors to determine the accuracy of the data;TABLE 1. Specifications of the Plate-Straightening Machines●exchanging data with the pump-battery station (PBS) of the PSM and transmittingthe station’s operating parameters to the upper-level system for display;●receiving signals from the upper-level system for manual control of the machine andthe PBS;●obtaining initial data from the upper-level system for automatic correction andtransmission of the data in order to make the appropriate adjustments.The functions of the upper-level automation system are as follows:●entering data on the straightening regimes for subsequent selection of the regime andrecording that information in a database;●manually choosing the straightening regime from the database for the correspondingplate (this is done by the operator);●automatically choosing the straightening regime from the database on the basis ofinformation obtained from the upper-level system;●manually controlling the machine in the straightening and cassette-replacementregimes;●indicating the positions of the mechanisms based on readings from the sensors andthe positions of the limit switches;●indicating the presence of a plate in the working zone of the PSM;●indicating the temperature of the plate measured by the pyrometer;●visually representing the straightening regimes and machine adjustments;visually representing the state of the machine’s mechanisms and the PBS for diagnostic purposes.Remote input-output module ET200 is used to supply power to the unregulated drives.The cabinet containing the relays and contacts for these drives is located a considerable distance from the e of the module has made it possible to significantly shorten the connecting cables.Diagnostic System. The heavy concentration of electrical and hydraulic equipment included as part of the PSM–equipment which is located an appreciable distance from the machine itself and is often in hard-to-reach places–makes it more difficult to service the machine and locate the source of problems.To facilitate maintenance of the PSM and shorten repair time, it was necessary to build an advanced diagnostic system.The system is based on an industrial computer installed at the control post.It diagnoses the state of various mechanisms of the PSM, as well as its hydraulic and electrical equipment.The system can be used to evaluate the condition of the automatic switches, the temperature sensors of the motors, the linear displacement gages, terminals of the local PROFIBUS network, the currents, speeds, and direction of rotation of the motors, and other equipment and parameters.The diagnostic system can also be used to establish the operating protocol of the PSM.Its archives contains data on the time and types of errors and equipment failures that occur, the coordinates of the mechanisms, motor currents and speeds, and other information.To make the control system more reliable, the software and hardware of the diagnostics station are identical to the corresponding components of the control system’s upper level.When problems occur with the operation of the control computer, the PSM control functions can be transferred to the computer of the diagnostic system.Conclusions.The NKMZ has worked with its original partners in the Commonwealth of Independent States (CIS) to successfully introduce plate-straightening machines equipped with a modern automated control system. Use of the machines makes it possible to minimize and almost completely eliminate the dependence of the quality of the finished plates on the skill of the machine operator.The control system, together with its convenient user interface,allows even personnel with no special training to quickly master the operation of the machine.The production of high-quality products is assured as a result of the exact movements of the machine’s mechanisms and the accuracy with which their positions are maintained, which owes to the use of precision equipment with proportional control and special controlalgorithms.In addition, the machine is equipped with a sophisticated diagnostic system which also records its key operating parameters.The availability of the system facilitates maintenance and repair of the machine’s many complex components.译文：现代化矫直轧制薄品设备的自动化控制谢韦尔钢铁公司在2003年8月成功完成了新引进的规格为2800—5000米尔的直线式钢板矫直机（平台相关模型）。

进入90年代，我国在赶超世界先进水平方面又迈出了一大步，一些新研制的矫直机获得了国家的发明专利，一些新成果获得了市、省及部级科技成果进步奖，有的获得了国家发明奖。

近年来，我国在反弯辊形七斜辊矫直机、多斜辊薄壁转毂式矫直机、平行辊异辊距矫直机及矫直液压自动切料机等研制方面相继取得了成功。

1.1.2 矫直作用经过轧制和热处理的管材存在一系列缺陷，其中主要的是纵向弯曲和横断面的椭圆度。

为了消除这些缺陷，需要设置斜辊式钢管矫直机。

在矫直过程中，钢管在矫直辊间作直线前进的同时还进行旋转运动，通过钢管在矫直辊中反复多次弹性弯曲使钢管达到矫直的目的。

1.2 矫直设备分类1.2.1 矫直机的分类按照工作原理不同，矫直机可以分为五大类。

第一类称为反复弯曲矫直机，它们是靠压头或辊子在同一平面内对工件进行反复压弯并逐渐减小压弯量，直到压弯量与弹复量相等而变直。

第二类称为旋转弯曲式矫直机，是工件在塑性弯曲状态下以旋转变形方式从大的等弯矩区向小的等弯矩区过渡，在走出塑性区时弹复变直。

第三类称为拉伸矫直机，它依靠拉伸变形把原来长短不一的纵向纤维拉成等长度并进入塑性变形后经卸载及弹复而变直。

圆钢矫直机毕业论文

圆钢矫直机毕业论文圆钢矫直机毕业论文引言：圆钢矫直机是一种用于将直径较小的圆钢条进行矫直的机械设备。

由于圆钢的使用广泛，矫直工艺对圆钢的质量和性能有着重要影响。

因此，开发一种高效、稳定、精确的圆钢矫直机对于加工圆钢材料具有重要意义。

本文将从机械结构设计、控制系统设计、运动学仿真分析等方面，对圆钢矫直机进行研究与分析，以期提高圆钢矫直机的工作效率和矫直质量。

一、机械结构设计圆钢矫直机的机械结构设计主要包括矫直轮、传动系统和支撑结构。

矫直轮是圆钢矫直机的核心部分，其质量和性能对矫直效果有着决定性影响。

传动系统负责驱动矫直轮进行工作，因此其结构设计必须具备稳定性和高效性。

支撑结构则起到稳定和支撑的作用，对整个圆钢矫直机的性能和寿命也有重要影响。

针对这些问题，本文提出采用重型钢材作为矫直轮的材料，并通过优化设计来增加矫直轮的硬度和韧性。

同时，采用带有减速装置的电动机作为传动系统的驱动源，以提高传动系统的工作效率和稳定性。

在支撑结构的设计上，本文运用有限元方法进行模拟分析，以确保圆钢矫直机的稳定性和寿命。

二、控制系统设计圆钢矫直机的控制系统设计对于机器的自动化程度和矫直质量有着至关重要的影响。

本文设计了一种基于PLC 的控制系统，通过编程实现对圆钢矫直机各个部件的控制和监控。

控制系统分为两个部分，一个是上位机，负责与操作人员进行交互，并实时监控机器的工作状态；另一个是下位机，负责控制各个执行机构，如电动机、减速装置等。

通过上位机与下位机的通信，可以实现对圆钢矫直机的远程控制和监控。

三、运动学仿真分析为了验证圆钢矫直机的工作效果，本文对其进行了运动学仿真分析。

通过建立圆钢矫直机的运动学模型，采用计算机仿真的方法，模拟矫直轮对圆钢进行矫直的过程，并观察矫直效果。

仿真结果表明，圆钢矫直机能够对圆钢进行高效、精确的矫直。

通过调整矫直轮的角度和速度，可以控制圆钢的形状和质量，满足不同需求。

结论：本文对圆钢矫直机进行了机械结构设计、控制系统设计和运动学仿真分析等研究与分析。

φ325钢管矫直机主传动系统设计学士学位论文

Φ325钢管矫直机主传动系统设计摘要在市场行情日益紧张的今天，钢管行业供需矛盾进一步恶化，无缝钢管厂库存创新高，个别民营钢厂因连续亏损出现停产现象。

为了在竞争中取得优势，只有靠质量取胜。

目前，国内无缝钢管的生产主要还是依靠热轧技术，而在热轧的过程中，钢管会存在纵向弯曲和圆度误差,这些缺陷是通过矫直工艺来予以消除的。

因此,矫直工艺决定了无缝钢管的几何形状,同时也影响其力学性能。

在矫直过程中,如果矫直机调整合适,可以消除无缝钢管的纵向弯曲和圆度误差,并能适当提高其力学性能。

目前，国内外的矫直技术飞快发展，其中以多辊矫直机应用最为广泛。

本次设计的主要目的是进一步掌握矫直机主传动系统，并对主其要部件进行设计和计算校核。

在查阅大量文献和了解相关知识，并且到鞍山钢铁集团公司无缝钢管厂Ø219、Ø159和PQF三条国内先进的生产线进行实习调研，掌握现代轧管机的发展及设备结构特点状况后，确定了两台电机通过万向接轴直接带动工作辊工作的总体传动设计方案。

通过对矫直机的主要力能参数的计算，合理选择电机，联轴器、减速器主要零件以及万向联轴器和连接轴，并进行强度计算和校核。

同时，确定润滑方式，并进行经济性和环境保护的分析。

数控钢筋调直机设计论文_本科论文

1 前言1.1 课题的背景和意义伴随着建筑业的迅猛发展，建筑钢筋的用量在迅速增加，建筑行业大都趋于使用带肋钢筋(螺纹钢筋)。

该钢筋大都为圆形盘料，钢筋弯曲较大，无法直接使用，因此就需要对其进行调直。

当今建筑工地大都使用人力或半自动化这些传统方式对盘料钢筋进行调直剪切。

此种方法不仅耗费大量人力物力而且劳动生产效率很低。

传统的调直方法已经满足不了现代化生产的要求。

数控钢筋调直机则应运而生，它是一种高效率、高质量的钢筋加工设备，可实现钢筋的定尺剪切。

数控钢筋调直机的自动化程度高，生产效率高，钢筋的调直质量好，与传统方式相比可以节省大量的人力物力，其中最重要的是调直的精度高，质量好，可以实现无划伤调直，大大提高了被调直钢筋的质量。

它在提高建筑工程质量上起着十分重要的作用，同时对加快建筑生产和建工速度，也具有十分重要的作用。

1.2 国内外调直理论研究及发展现状国外在调直理论和技术的研究方面起步比较早，具有一定程度广泛性，并且取得了显著的研究成果。

与此同时国外的许多研究成果已经被应用于实际生产中，并产生了相当可观的的经济效益。

国外一些调直技术发展较发达的国家，已经形成了一系列的调直设备。

同时他们还在钢筋调直理论、工艺和设备的研究方面也进行了大量的工作，并取得了一批较有影响的成果，同时生产一些具有世界先进水平的钢筋调直设备，例如数控钢筋调直机、数控调直切断机等。

国内在调直理论和技术的研究方面也做了很大的努力，使调直理论和技术的研究工作得到了广泛的重视，同时也取得了一些令人瞩目的研究成果。

其中部分成果的一处与世界领先水平。

目前我国已拥有了自行设计和生产板、带、线、型、管材的调直设备的能力，设备的精度和控制水平也在不断提高。

在引进和吸收国外先进的钢筋调直设备和技术的基础上，我国在数控钢筋调直机、数控钢筋调直切断机方面的生产水平也在不断提高，并涌现了例如天津建科等一些发展较好的钢筋设备生产厂家，而且其生产的例如数控钢筋调直机具有十分先进的调直技术，具有生产效率高、自动化程度高等特点。

机械毕业设计692钢筋矫直切断机的设计正文

1．绪论1．1国内外钢筋矫直切断技术的发展状况钢筋矫直切断机在建筑行业运用广泛，国内外对钢筋矫直切断机的研究也比较多，国内对于钢筋矫直切断机的需求空间很广，但国内的矫直切断机只能满足一般的需求，对于一些矫直精度较高，切断质量要求也较高的钢筋就无法满足了，需要从国外进口有关设备，总体来说国内的技术还落后于国外。

由于冷轧带肋钢筋需要经矫直切断后才可使用，但目前对于冷轧带肋钢筋矫直的理论研究还不是很完善，冷轧带肋钢筋矫直的无划伤问题一直没有得到很好的解决，冷轧带肋钢筋矫直机的系统参数设计也主要是依据普通圆钢筋矫直机的有关参数。

国内还没有能满足矫直性能要求的数控冷轧带肋钢筋矫直切断机，而从国外进口一台数控冷轧带肋钢筋矫直切断机需要8万美元，一般用户难以承担。

市场上急需一种矫直质量较好、自动化程度及生产效率较高的矫直切断机。

国内的机器最缺少的技术就是矫直技术了，而这一方面国际上有些国家发展的较好，如前苏联，德国和日本在这方面起步较早。

国内有关技术人员也在矫直理论和技术的研究方面作出了很大的努力，其中有部分成果的水平居领先地位，如列入1998河北省企业技术开发第二批计划的GTK6/12数控冷轧带肋钢筋矫直切断机已经解决了有关技术上的难题其水平已达到国内领先地位，它在提高矫直质量、保证矫直后钢筋表面无划伤的基础上，采用了数控技术，提高了自动化程度，实现了自动定长切断、记数（钢筋长度、单根重量、总重、钢筋总数）及自动停车等功能。

1．2冷轧带肋钢筋的概述1．2．1钢筋的种类建筑上常用的钢筋分为热轧钢筋，冷拉钢筋，热处理钢筋，钢丝和钢绞线等许多类。

在常温下对钢筋进行加工称为“冷加工”。

用冷加工方法可以使热轧钢筋的强度得以提高，是节约钢材行之有效的方法之一。

常用的冷加工方法有冷拉和冷拔两种，近十年来，又发展了冷轧和冷轧扭等方法。

冷轧带肋钢筋是采用强度较低，塑性较好的普通低碳钢或低合金钢热轧圆棚条钢筋为母材，经冷轧或冷拔工艺减径后在其表面冷轧成具有三面或两面月牙形的钢筋。
