Cold Hydraulic Extrusion Press System 1. Description of cold hydraulic extrusion machine The machine including two set of machine: 1) YJ650: process rebar whose diameter is from 16mm to 32mm. 2) YJ800: Process rebar whose diameter is from 36mm to 40mm. 3) YJ650 machine and Pressure equipment of YJ800 can process diameter 16-40mm. 2. Working principle It can link the rebar with sidewise extrucion by the cold extrusion press machine, make the coupler plastic deformation then occlude tightly with the steel in order to link the rebar. 3. Advantages a. Because of good resistence of the joint,it is widely used in bridge cons...
