摘　　要：研究了分瓣热胀形模具结构、模具材料及其工艺参数等对钛合金筒形件胀形精度的影响。结果表明，分瓣热胀形是高精度钛合金筒形件的一种有效成形方法，分瓣热胀形TC4钛合金φ200mmx700mm筒形件的径向尺寸精度和母线直线度分别达到±0.03mm和0.11-0.17mm。The cylindrical parts forming tech-nology of TC4 titanium alloy is studied by hot bulging process. The experiments focus on analyzing the effects of dies structure, bulging dies materials and processing parameters on the precision of specimen size. The results indicate that the hot bulge forming process is a very ef-fective method for forming the TC4 titanium alloy cylin-drical parts. The accuracy of radial dimension and linear ofφ200mmx700mm cylindrical part are ±0.03mm, 0.11~0.17mm, respectively.
