冲裁力的计算对于冲压生产是很重要的。通常计算冲裁力用的基本公式为:P=1.25δLσ_(cp)或P=δLσ_b 式中:P——冲裁时所需要的压力(公斤) L——冲裁件的周长(毫米) δ——冲裁材料厚度(毫米) σ_(cp)——材料的抗剪强度(公斤/毫米~2) σ_(b)——材料的抗拉强度(公斤/毫米~2) 下面介绍两个简便的冲裁力速算公式,如果采用这两个公式计算,可以简便而迅速地算出冲裁力。冲裁圆形工件或冲圆孔时冲裁力计算公式为:
The calculation of blanking force is very important for stamping production. The usual formula for calculating the blanking force is: P = 1.25δLσ_ (cp) or P = δLσ_b where: P - the pressure required for blanking (kg) L - the perimeter of the blanking member δ - thickness of the blanking material in mm σ_ cp - shear strength of the material in kg / mm 2 σ_ (b) - tensile strength of the material in kg / mm 2 The following describes two Simple punching force calculation formula, if you use these two formulas to calculate, you can easily and quickly calculate the punching force. Punching a circular workpiece or punching punch punching force is calculated as:
