一、连续模结构因素设计连续模时,要准确掌握加工速度、冲材材质、冲压力、工位数、模具间隙等各主要因素,否则就不能发挥模具的效用和综合加工方法,特别是在高速冲压精密件时,模具损伤多,工件精度低,得不到满意效果。以下分别叙述各要素。 1.冲压力压力机的加压能力以吨(tf)为单位,一般压力机所示吨位包含有1.2～1.5的安全系数。设计模具时,冲压力据冲材的材质与厚度、工件展开周边长度、弯曲压力、卸料力等求
First, the continuous mode structure factor design Continuous mode, to accurately grasp the processing speed, the material of red, stamping force, the number of positions, the gap between the mold and other major factors, or you can not play mold utility and comprehensive processing methods, especially in High-speed stamping precision parts, mold damage, the workpiece accuracy is low, not satisfactory results. Each element is described below. 1. Punching pressure Pressing capacity in tons (tf) as a unit, the general press tonnage contains 1.2 ~ 1.5 safety factor. Die design, stamping force, according to the material and thickness of the workpiece, the workpiece to start the surrounding length, bending pressure, unloading force, etc.
