冲裁间隙大小对冲裁力、冲件质量及精度、模具寿命、卸料力和推件力等,都有很大影响,所以正确地确定间隙大小,对冲裁工作是十分重要的。 间隙的大小和许多参数有关,其中主要的是材料机械性质和厚度。在选用间隙值时,应该满足下列要求:冲裁件的剪切断面质量要高;冲裁件要有较高的尺寸精度;最 Blanking gap size blanking force, quality and precision punch, die life, unloading force and pushing force, etc., have a great impact, so the correct size of the gap, the punching work is very important. The size of the gap depends on many parameters, the main ones being the mechanical properties and the thickness of the material. In the choice of the gap value, the following requirements should be met: the quality of the cutting section of blanking parts to be high; blanking parts have higher dimensional accuracy; the most
