Fine blanking is an effective and economical metal cutting process which produces very highly precise work pieces with completely smooth, tear-free sheared surfaces.
精冲是精密冲裁的简称,是一种经济有效的金属剪切工艺,精冲工艺可以获得光洁度高、无撕裂的冲裁面。
Blanking experiments were done, and the dynamic displacements of the slider were recorded. The press vibration can be judged based on the amplitudes.
设计了液压机冲裁减振试验系统,进行了几种方案的冲裁实验,记录了滑块的动态位移,由冲断时冲头的振动幅值判别振动的大小。
