摘　　要：利用热介质成形技术对TC4钛合金复杂方锥形零件进行了拉深过程计算分析,并与传统热冲压工艺的模拟结果进行了对比。结果表明,热介质成形工艺中运用柔性的固体颗粒介质代替刚性凸模,能有效改善成形零件的壁厚均匀性,降低起皱趋势,提高成形质量。Numerical simulation analysis of TC4 titanium alloy taper-shaped part is carried out by us- ing the technology of thermal deep drawing with heated media, the optimal process scheme can be achieved and the result shows that by substituting the rigid punch with solid granules in the process of deep drawing, the uniformity of the wall thickness of the forming part can be improved effectively and the tendency towards wrinkling is reduced thus the forming quality of the part could increase greatly.
