在冷冲模设计中,当冲压工序所需的工序尺寸与零件图纸上的原始尺寸不一致时,我们就必须把零件图上的原始尺寸,通过换算,变为我们所需要的某一工序的工序尺寸。这样既便于设计模具,又利于保证最后零件的合格。因此,正确掌握工序间尺寸计算方法是我们设计模具的关键之一。 下面先举例说明由于疏忽,易出现差错的情况。 图(1)为一个所需加工的零件。由于冲压加工工艺的需要,必须用复合,弯曲二付模具加工才能最后成形。很明显,在复合 In the die design, when the stamping process steps required size and parts drawings on the original size is inconsistent, we must the original figure on the part diagram, through conversion, we need to become a process step size . This is easy to design mold, but also conducive to ensure the final parts of the pass. Therefore, the correct understanding of the process between the size calculation method is one of the keys to our mold design. Let me give an example to illustrate the situation that is prone to error due to negligence. Figure (1) is a required processing parts. As the need for stamping process, you must use composite, bending the two molds to pay the final shape. Obviously, in the compound
