Abstract:

 Based on theoretical analysis and experimental verification, a multi-station cold forging process was provided to produce ball pin, and there were two options for the multi-station cold forging process of ball pin. In order to get the best forming scheme, two process schemes were simulated by finite element software Deform-3D, and the best process scheme was obtained by comparing stress-strain, forming load and material damage values of two process schemes. Then, the corresponding die was designed according to the best process scheme, and for the difficulty of demoulding the ball pin head, a floating Half parting mold scheme was provided. The experiments show that the ball pin forming is well-distributed, full-filled, no cracks, no flashes and other defects, and the floating Half parting mold splits smoothly. Thus, in the research of multi-station cold forging process, the application of finite element technology and the design of die and floating Half parting mold have certain reference value for the same type of research.
