模具零件在线切割加工中变形分析及解决对策

Deformation analysis and preventive measures of die & mould parts in WEDM

对线切割加工中模具零件变形问题产生原因进行了详细分析,如切割路线、工件装夹、材料选取、热处理工艺以及模具结构设计和工艺安排等。并提出预防和减小模具零件变形和开裂的现象的解决措施,对提高模具零件加工质量和使用寿命有着及其现实的意义。

The causes about deformation of die and mould parts in WEDM are analyzed, such as cutting lines, choosing material, mould structure and process. Then solution to prevent and reduce the deformation and crack of mould parts are put forward. So the process quality and service life of mould can be improved.
