Cold forging deformation analysis for stainless material using DEFORM

摘要

This paper proposes cold heading and piecing which is quite complicated process. The study is based on defor7mation simulation and compared the parameters of production processes to factory. DEFORM is used to run the simulation in the case of piecing and heading stainless steel. Effective simulation result is founded by 720 stokes. The maximum load which occurs on the 512 stoke is 8.22×10 N. The information is used for die and punch design. The 6 punch and 6 die design is effectively founded. The factory production process is successfully tested.
