探讨了薄料冲裁的主要工艺方法。基于薄板冲裁间隙小、模具制造难度大、对冲压设备要求苛刻的基本工艺问题,将目前常用的薄板冲裁工艺方法归纳为四大类,即聚氨酯橡胶冲裁法、辊压冲裁法、拉应力冲裁法、小间隙冲裁法等。阐述了这4种工艺的冲裁机理、模具结构、特点及适用场合等,对实践中薄板冲裁工艺方法的选择具有借鉴作用。

Based on the basic technology problems of the close clearance,difficult mold manufacturing and high requirement for the blanking equipment in the sheet blanking process,the major technology methods of the blanking were introduced.The currently common used methods were made into four categories: the polyurethane blanking,the roll blanking,the tensile stress blanking and the close clearance blanking.The blanking principle,the die structure,the characteristics and the application field of the four processing methods were introduced and it could be a reference for selecting the blanking process method in practical production.
