Abstract：

The article analyzes the forming process in detail,explains the forming difficulties of the CPU fin and compares the machine tooling with material utilization ratio to make sure the forming process and the effective forming method——forging.The mould structure of this part is introduced and the corresponding improvement measures are put forward based on the defects appeared in the practical application so as to meet the precision request and achieve the goal of batch production.
