Aiming at the problems in the production process of traditional drawing press for stainless steel flume, a proportional servo hydraulic control system based on XM21 motion controller and 4WRPEH high frequency proportional valve produced by Bosch rexroth was developed. The improved press has the advantages of fast response, high precision, stability and reliability, and the automatic production of stainless flume is realized. The running results show that using the system, the mold can be easily replaced, the debugging time is greatly shortened. The quality, stability and efficiency of products are improved greatly. It brings remarkable economic benefits to enterprises.
