钛板的差温拉深属新的工艺技术。通过拉深理论分析如例举了材料的平面各向异性指数定义,常见三种破坏形式,切向残余应力等说明采用差温一次拉深和一次整形代替了普通拉深需要5～6套模具的拉深,缩短工艺流程,减少模具套数,提高了经济效益。 The difference between titanium temperature drawing is a new technology. By drawing theoretical analysis, for example, the definition of the material plane anisotropy index, the common three forms of damage, tangential residual stress and other instructions to use a differential temperature and deep drawing a plastic instead of ordinary drawing requires 5 to 6 sets of mold The deep drawing, shorten the process, reduce the number of mold sets, improve economic efficiency.
