近年来,世界各国都在致力于冲裁零件精度的提高与剪切表面光洁度的改善。振动修边就是将留有一定余量的冲裁零件,在特种压床上用高频率(1200～2000次/分)、低振幅(0.05～0.6毫米)的振动压力,使零件通过模具将余量修去。用振动修边代替机械加工或钳工来修正凸轮、齿轮等具有复杂外形的小型高精度零件,可以大大提高劳动生产率和可靠地保证零件互换性要求。修边后零件的尺寸精度可达±0.005～0.01毫米,表面光洁度为▽▽▽7～▽▽▽8。由于它比一般修边有更优越的效果,因此在国外非但在钟表和仪器工业中首先得到
In recent years, all countries in the world are devoted to improving the accuracy of blanking parts and improving the surface finish of cuttings. Vibratory trimming is to leave a certain margin of the blanking parts, special presses on the high-frequency (1200 ~ 2000 times / min), low amplitude (0.05 ~ 0.6 mm) vibration pressure, the parts will be the remainder of the mold Repair it. Vibration trimming instead of machining or fitter to amend the cam, gear and other complex high-precision parts of the shape, can greatly improve labor productivity and reliable parts to ensure interchangeability requirements. Trimming parts size accuracy up to ± 0.005 ~ 0.01 mm, surface finish ▽ ▽ ▽ 7 ~ ▽ ▽ ▽ 8. Because it has more superior trimming edge than the general effect, so not only in the foreign countries in the clock and instrument industry first
