采用电火花机床来加工复式冲模,必须先将复式模具的冲头用夹具固定好,然后用锑铋合金固定。为了使冲头按图纸要求等分固定好,对于垫块的几何尺寸必须计算精确,否则将严重影响产品质量。这里介绍一个简单的计算公式,便能很方便地精确计算垫块的几何尺寸。一、平行的垫块计算图1是垫块位置示意图、垫块尺计k是要计算的关键尺寸。
EDM machine used to process double die, die first punch must be fixed with a fixture, and then with antimony bismuth alloy fixed. In order to make the punch fixed according to the requirements of the drawing, the geometrical dimensions of the pad must be calculated accurately, otherwise the quality of the product will be seriously affected. Here to introduce a simple formula, you can easily and accurately calculate the spacer geometry. First, the parallel pad calculation Figure 1 is a schematic diagram of the pad position, pad foot gauge k is to calculate the key dimensions.
