在机械传动中或生产自动线上,由于需要将某种沉重的机构移动一直线距离,或转过一个角度,而且还要求有较高的位置精度,则必须采用液压随动系统,或称伺服系统,又称伺服传动.随着我国社会主义工业的发展,在国防工业、冶金、轧钢、机械制造以及锻压机械中,愈来愈广泛地采用以电气-液压随动系统构成的自动控制.本文只就随动系统的基本原理及其在锻压机械中的应用作一般性的介绍. 大型水压机的进、排水阀,因其上作用高压水的压力很大,所以开启阀门所需要的力也很大.锻造操作机的液压夹钳将钢锭钳住并前后送进,或左右旋转,也需很大的操纵力或操
In mechanical transmission or automatic production line, due to the need to move a heavy body of a certain distance or straight line, but also requires a higher position accuracy, you must use hydraulic servo system, or servo system , Also known as servo drive.With the development of socialist industry in our country, more and more widely used automatic control system composed of electro-hydraulic servo system in defense industry, metallurgy, steel rolling, machinery manufacturing and forging machinery. On the basic principles of servo system and its application in forging machinery for general introduction.Whole hydraulic press, drain valve, because of the pressure on the role of high-pressure water, so the required force to open the valve is also great. Hydraulic forging operation of the hydraulic clamp pliers to live and feed before or after, or left and right, also need a lot of control or manipulation
