众所周知,确定冲裁件的压力中心是设计冲裁模的重要工作内容之一。生产实践表明:当冲裁件压力中心偏移冲床工作压力作用线较远的时候,会造成冲床导向机构(如滑块与导轨)的早期磨损,并对模具的使用性能和寿命产生不良影响。对于厚料小孔冲裁和精密冲裁来说,保证压力中心的准确性则更为重要。因此,设计冲裁模时应当尽可能地保证压力中心的准确性。 As we all know, to determine the center of the stamping blanking die design is an important part of the work. Production practice shows that when the blanking pressure center is offset from the working pressure of the punch, the early wear of the punch guide mechanism (such as the slider and the guide rail) will be caused, which will adversely affect the serviceability and service life of the die. For thick hole punching and precision blanking, to ensure the accuracy of the pressure center is even more important. Therefore, the design of blanking die should be as accurate as possible to ensure the pressure center.
