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,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。
五金冲压件材料的硬度检测,其主要目的就是确定购入的金属板材退火程度是否适于随后将要进行的冲压件加工,不同种类的冲压件加工工艺,需要不同硬度级别的板材。
stamping material hardness testing, the main is to determine whether the purchase of metal sheet annealing is suitable for subsequent stamping parts processing, different types of stamping processing technology, the need for different hardness levels of the plate.
在冲压件行业里,冲压有时也称板材成形,但略有区别。所谓板材成型是指用板材、薄壁管、薄型材等作为原材料进行塑性加工的成形方法统称为板材成形,此时,厚板方向的变形一般不着重考虑。
In the stamping industry, stamping is sometimes referred to as sheet metal forming, but there is a slight
The so-called sheet forming means the forming method of plastic forming with sheet, thin-walled tube and thin material as raw material, which is called sheet forming. At this time, the deformation of the thick plate is generally not cidered.
