Investigation and Application of Cold Extrusion Forming Process in Die Structure Design of Plug Extremity

Abstract:

a cold extrusion forming process in die structure of plug extremity is analyzed in this paper, its technological data on the tooling structure design of plug extremity are discussed, and the die architecture design and key technology in the automatic extrusion machine for plug extremity with cold extrusion forming approach were accomplished. This plug extremity equipment developed with cold extrusion forming process technology can not only achieved the process of delivering material, extruding forming and cutting-off material in automatically, but also enhanced the rigidity and intension at two ends of plug. The production efficiency and the material used ratio were increased greatly, the manufacturing cost was decreased obviously, and the plug quality with cold extrusion forming method was ensured.
