增设强压功能。即对卸料镶块压料部加厚尺寸(正常的卸料镶块厚H 0.03mm),以增加对凹模侧材料的压力,从而*冲切时冲压件产生翻料、扭曲变形。
Additional pressure function. In order to increase the pressure on the material of the die side, the pressure of the material in the die side is increased by the thickness of the material of the unloaded insert (normal unloaded insert thickness H 0.03mm),fastener报价, so as to suppress the turning and distortion of the stamping parts.
合理的模具设计。在级进模中,大庆fastener,下料顺序的安排有可能影响到冲压件成形的精度。针对冲压件细小部位的下料,一般先安排较大面积之冲切下料,再安排较小面积的冲切下料,fastener厂家,以减轻冲裁力对冲压件成形的影响。
Reasonable mold design. In progressive die, the order of blanking sequence may affect the accuracy of stamping forming. In order to reduce the impact of punching parts, the punching and cuttin*anking of *all area is arranged in the light of the blanking of the *all parts of the stamping parts.
设计的冲压件必须形状简单,结构合理,以有利于简化模具结构、简化工序数量,即用*少、*简单的冲压工序完成整个零件的加工,减少再用其他方法加工,并有利于冲压操作,便于*实现机械化与自动化生产,以高劳动生产率。
设计的冲压件,在保证能正常使用情况下,尽量使尺寸精度等级及表面粗糙度等级要求低一些,并有利于产品的互换,fastener型号,减少废品、保证产品质量稳定。
设计的冲压件,应有利于尽可能使用现有设备、工艺装备以及工艺流程对其进行加工,并有利于冲模使用寿命的延长。
