Abstract：

The cold stamping process of 5A06 aluminium alloy T-shaped semi-pipe with variable diameter was optimized, and the forming process of the part was simulated by software Dynaform. Then, the blank size and die fillet of the part were analyzed in detail, and the process and tooling parameters were optimized. The results show that irregular hexagonal blanking size is more advantageous to part forming than rectangular blanking size to avoid cracking at the fillet and the transition zone of die surface. When the die radius is R10 mm, the qualified parts can be formed to meet the requirements. The experiment was used to verify that the experimental results are consistent with the finite element simulation results, which proves the correctness of the simulation.
