Abstract:There are three main work posts in this warm forming extruder for steel connection,they are up setting station,backward extrusion station and blanking station.In order to reduce manual labor intensity and enhance automation level of an enterprise,a warm extrusion forming process manipulator for steel connecting sleeve typically was developed and used to pass workpieces from one station to another of the three posts.The working principle of the manipulator was described,in the same time,some hydraulic circuits and hydraulic control circuits were designed.The manipulator can have function of clamp force automatic regulating and run smoothly,which has the advantages of high efficiency in processing and low cost,and can meet requirements in practices of an enterprise.
