Notes:
This paper analyzes the forming process methods of fin used in CPU chip to emit heat.The whole process is blanking, the first forging forming, the second forging (sizing), and trimming.The chamfer design of CPU fin blank is simulated by finite element analysis. The optimizedchamfer 1.6 mm is available. Semi-enclosed cold forging of progressive dies is put forward. Thenewly designed transfer unit is applied, which unifies the merit of high efficiency of the progressivedies and the high material-using ratio of the project die. Quick disassembly structure is designedand pins are used as quick disassembly pins by means of ball bearing bushing. The uniqueprocessing of the shearing scrap structure is adopted when designing the inverted trimming dies.Compared with the traditional die, the mechanization and electrization are realized to increase theproduction efficiency and get highly precise CPU fin
