摘要:
采用板料成型仿真软件Pamstamp对钛合金Ti-15-3材料弧板零件冲压成型回弹进行仿真计算，预测了不同阴模型面圆弧尺寸冲压成型后的回弹量。依据计算结果优选的阴模型面圆弧尺寸设计了成型模具，并进行了冲压成型试验。零件试验件型面尺寸与设计型面尺寸最大相差0.15 mm，满足不大于0.2 mm的要求。结果表明：采用仿真软件Pamstamp进行回弹仿真计算对Ti-15-3材料弧板成型模具设计和零件快速制造是可行的；采用本计算结果减少了模具返修次数，降低了成本，提高了钣金成型质量和生产效率。
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.
