五金标准冲压件模具的维护和保养方法

文章出处:庆辉五金  发布时间:2019-11-28
一般来说,五金冲压件选材应遵从的4个准则:
1、关于定尺板尽量挑选适宜的标准尺度,从钢厂剪切完结后,不必进行二次剪切,下降剪切费用;关于卷板,尽量挑选开卷成形的卷料标准及工艺,削减二次剪切的工作量,进步工作效率。
2、板材的厚度存在误差要求,通常在误差答应的范围内,应首先选用下误差的板材。
3、断定五金冲压件打开板料的形状及尺度,是剖析冲压件变形程度,规划工艺性及拟定工艺规程的条件。假如板料形状适宜,不仅变形沿板料散布不均匀的现象能够得到显着改进,并且成形极限也可有所进步,并能下降突耳高度,削减切边余量。此外,关于某些落料后直接成形的零件,若能给出准确的板料形状及尺度,则能削减试模调模的次数,从而缩短出产周期,进步出产率。
4、在产品规划选材时,防止选用高商标的原料形成产品功能过剩,一起,在满意产品、工艺要求的条件下,尽量挑选现有已量产车型所用的原料、料厚,形成资料渠道,为后续的收购、库存办理供给便当。
