Abstract:
The simulation software Pamstamp is used to perform a simulating calculation for the spring-back magnitude of Ti-15-3 titanium alloy plates with arc formed by stamping to predict the resilience value of Ti-15-3 titanium alloy plates stamped with different size female die. The forming die was designed according to the calculation and optimization results of female die surface arc. The maximal profile difference between test specimen and designed part is 0.15 mm, which meets the requirement being less than 0.2 mm. The result shows that it is feasible to use the simulation software Pamstamp to perform the spring-back simulation calculation for design of arc plate dies and rapid manufacture of parts. The method can reduce number of die repair, lower the cost, promote the arc plate forming quality and improve the production efficiency.
