双辊驱动五辊冷轧机的设计

双辊驱动五辊冷轧机的设计

摘要

冷轧钢板和带钢近年来得到较大的发展，自二十世纪八十年代开始出现了全连续冷轧机，这种轧机只要第一架引料后，可实现连续轧制。全连续冷连轧机可以提高生产率30~50%，产品质量和成材率也得到很大提高。随着工业生产的发展，对极薄带材要求增加特别是微电子工业对极薄带材要求更高。而轧制薄带要求轧辊直径更小。

本设计针对某厂冷轧生产线中的主体设备轧机进行了改进设计，又原来的四辊改为五辊，对改进后的轧辊及机架等主要零件进行了强度校核。

在设计中，首先对设计轧机的方案进行了选择和评述，然后计算了轧制时所需要的力和力矩，从而确定了主电机的容量，并对电机进行了校核。计算了轧辊尺寸并校核了它的强度。本设计还计算了压下系统：压下螺丝的主要参数、其传动力矩及换算到电机上的静力矩，确定了压下螺母的尺寸并对压下螺母进行了校核。对机架的尺寸、应力进行了计算及其强度的校核。对联接轴也进行了计算，分析计算了扁头，并对其进行了强度的计算

在最后，对整个轧机的润滑方法、试车方法和对控制系统进行了评述，并对其进行了经济效益分析。

经过计算和校核，改进后的轧机满足工艺要求，改进的五辊轧机结构合理。

Abstract

Cold rolling steel plate and the hoop obtained the big development in recent years, started from 1980s to appear the entire continual cold-rolling mill, after so long as this kind of rolling mill first directed the material, might realize the continual rolling. All continuously the cold company rolling mill may enhance productivity 30~50%, the product quality and becomes a useful adult rate also obtains the very big enhancement. Along with the industrial production development, the antipode thin strip request increases is specially the micro electron industry antipode thin strip request is higher. But the rolling thin belt requests the roller diameter to be smaller.

This design has carried on the improvement design in view of some factory cold rolling production line in main body equipment rolling mill, also the original four rollers change five rollers, to improved after the roller and the rack and so on the major parts has carried on the intensity examination.

In the design, first to designed the rolling mill the plan to carry on the choice and the narration, then has calculated when the rolling needed strength and moment of force, thus had determined the host electrical machinery capacity, and has carried on the examination to the electrical machinery. This design also systematically calculated depress the system: The housing pin main parameter, its driving moment and convert on the electrical machinery the static torque, had determined depress the nut the size and to depress the nut to carry on the examination. To the rack size, the stress have carried on the computation and the intensity examination. The antithetical couplet coupling spindle also carried on the computation, the analysis has calculated the flat head, and has carried on the intensity computation to it In finally, to the entire rolling mill lubrication method, the test run method and has carried on the narration to the control system, and has carried on the economic efficiency analysis to it.

After the computation and the examination, after the improvement rolling mill satisfies the technological requirement, the improvement five roller structure is reasonable.
