1400毫米冷轧精整机组卷取部分设备液压传动
系统设计
摘要
冷轧带钢是钢铁工业的主要产品之一,它是汽车、家电、造船、航空航天等行业的重要原材料,带钢适合国民经济和人民生活需要,得到广泛应用。冷轧是冷轧带钢生产中的一个重要工序,液压技术在冷轧中应用十分广泛,此次设计的是1400毫米冷轧精整机组卷曲部分设备液压系统,1400毫米冷轧精整机组卷取部分设备设备由卷取机、卸卷机、传递小车、以及升降移送机构等组成,其动作由液压传动装置控制。这是冷轧时一个比较重要的工序,本系统主要有四个支路组成:卸卷车升降缸的升降动作,卸卷车移送缸的水平移动,传递小车升降缸的升降动作,传递小车移送缸的水平移动。在设计过程中,对各支路的受力进行详细的计算,对各元件的选用进行详细的说明,对液压执行元件、液压阀、液压辅助元件和泵站进行详细的设计。

1400 millimeters of cold Ya Jing whole machine set book take a parts of equipments liquid to press to spread to move a system design
Abstract
Cold Ya's taking a steel is a steel industry of one of the main products, it be the importance of the professions, such as car, appliance, shipbuilding and aviation aerospace...etc. original material, take a steel in keeping with national economy and people life demand, get extensive application.The cold Ya is , in the cold Ya that take a steel to produce of an importance work preface, the liquid press a technique in the cold Ya application very extensive, this time design of is 1400 millimeters of cold equipments liquid with parts of curl of the Ya Jing whole machine set to press system, 1400 millimeters of cold equipments equipments with parts of curl of the Ya Jing whole machine set be taken machine by book, unload a machine, deliver a small car, and ascend and descend move to send to organization's etc. to constitute, it action is press by the liquid to spread to move to equip control.This be the cold Ya 1 more the work preface of importance, this system be main to have four the road constitute:Unload a car ascend and descend an ascend and descend of urn action, unload a the level that the car move to send an urn move, deliver a small car rise and fall ascend and descend of urn action and deliver a small car to move level of send the urn move.In the design process, rightness each being carry on by dint of road detailed of calculation, use to carry on expatiation to choose of each component, to the liquid press performance component, liquid to press valve, liquid to press assistance component and pump station to carry on detailed of design.
