长期以来,航空辅机工厂的各种冷冲压模具多半都是采用精度较高的导柱和导套作导向机构的,没有充分利用冲床滑块的导向精度,这对于精度要求高的军品来说是完全必要的。但目前各军工厂都有不同程度的民品生产任务,一般来说,民品的精度要求较低,而且进度要求急,且产品更新换代快,我们摸具设计者如何适应这一新的要求呢?若采用普通的无导向敞开式模具,由于它没有导向机构,虽然结构简单、制模周期短、成本低,但是在使用中对摸很困难,既费时又费劲,且不易保证产品质量。为了解决这一难关,我们先后在几个产品的拉深模,翻内孔模和压凹槽以及压印等模具中使用了调(对)模导向零件——对模套
For a long time, most of the cold stamping dies in the aviation auxiliary machinery factory adopt the guide pins and guide sleeves with high precision as the guide mechanism, and do not make full use of the guiding precision of the punch slider, which is not suitable for military products with high precision requirements It is absolutely necessary. However, at present, all military factories have different levels of production tasks of civilian products. In general, the requirements for the quality of civilian products are relatively low, and the progress is urgent, and the products are updated rapidly. How do we meet the new requirements of designers? If using a common non-oriented open mold, because it has no guide mechanism, although the structure is simple, short molding cycle, low cost, but the use of the touch is very difficult, both time-consuming and laborious, and not easy to ensure product quality. In order to solve this difficult problem, we have used the mold guide (mold) guide molds for several products such as drawing dies, counterbore and pressure grooves and embossing,
