厚钢板的冲裁由于在模具的强度、寿命和冲件质量等方面存在着一定的问题,所以仍以气割、锻压加工较多,而以冲裁加工较少。本文较详细介绍厚钢板冲裁经验,供参考。一、冲裁间隙值的确定过去我们确定冲裁间隙时,一般是按料厚的6%~10%选定的,如果利用此间隙值冲裁厚钢板,其实际冲裁力将远远超过设计冲裁力,给设计和生产带来困难,问题发生的关键原因,就是冲裁间隙偏小。特
Thick plate blanking due to the strength of the mold, life and quality of the pieces there are some problems, it is still gas cutting, forging more, but to punching less. This article describes the experience of blanking thick steel plate for reference. First, determine the value of blanking clearance In the past we determine the blanking clearance, the general is based on the material thickness of 6% ~ 10% selected, if the use of this gap value punching thick steel plate, the actual blanking force will far exceed Design punching force, to design and production difficulties, the key reason for the problem is punching gap is small. special
