Abstract：

The common ECAP is non-continuous extrusion with L-shaped channel structure mold at present. The mold structure is of shortage and not good at continuous reciprocating extrusion especially. The improved structures of die and workbench of press were proposed，by which the L-shaped channel die was displaced by a U-shaped channel die, and a moving workbench device and its motion control system were attached to the fixed workbench of common hydraulic machine in order to precisely control the movement and position change of the extrusion die on the workbench. Thus, by the device, a continuous reciprocating multi-pass extrusion of block material could be achieved without removing the samples. And the material after extruding is of ultra-fine grain structure.
