复合材料液压机新型全行程调平电气控制系统

New electrical control system for full-range leveling of composite hydraulic press

随着汽车轻量化的全世界推广,多种新型复合材料的逐渐应用,对复合材料液压机的调平精度有了更高的要求。文中主要介绍了新型全行程主动四角调平电气控制系统,通过对压机空载下行过程、压制过程、保压过程、脱模过程进行全行程调平和全行程闭环控制,从而提高了复合材料液压机四角调平的精度,提升了产品的均匀度。主动式四角调平系统的应用,解决了被动式四角调平系统不能进行全行程调平的弊端,从而进一步提高了复合材料合格产品的成型率。

With the popularization of automobile lightweight and the gradual application of a variety of new composite materials,there is a higher demand for the leveling accuracy of the composite hydraulic press.This paper mainly introduces a new type of full-stroke active four-angle leveling electrical control system,through the press no load down process,pressing process,pressure maintaining process,demoulding process of full-stroke leveling and full-stroke closed-loop control,so as to improve the composite hydraulic press four-angle leveling accuracy,improve the product uniformity.The application of active quadrangle leveling system solves the disadvantage that passive quadrangle leveling system can’t carry out full stroke leveling,thus further improving the molding rate of qualified composite products.
