Research of Cold Extrusion Process for the 2A12 Duralumin Pistons

Abstract:

The existing process of 2A12 aluminium alloy piston is cutting completed by hot- drawing pole , as a material utilization rate less than 40%. In order to improve material utilization, cold-extrusion process is the reasonable choice, but only if solve the annealing before cold-extrusion, surface lubricated, the Parameter optimization of cold-extrusion and quenching process after extrusion. This research uses the DEFORM finite element analysis and a good effect in practical application is obtained to enhance the rate of more than 80% material utilization, scrap rate is less than 0.5%.
