弹性元件是仪表的心脏,其质量直接影响仪表的性能和精度。随着科学技术的不断提高,尤其是近年来尖端技术的发展,弹性元件的材料种类和厚度不断变化,冲件的质量要求越来越高,极薄料(厚度最薄为0.03±0.002mm)模具间隙的选用已成为仪表行业非常突出的问题。五十年代起,很多工厂沿用苏联制订的冲裁间隙值,数值相对偏小。六十年代,国内一些单位使用大间隙后,冲裁件质量和模具寿命都有较大提高,大间隙从而在国内逐渐得到推
Elastic element is the heart of the instrument, its quality directly affects the performance and accuracy of the instrument. With the continuous improvement of science and technology, especially the development of cutting-edge technologies in recent years, the types and thicknesses of elastic elements vary constantly and the quality requirements of the pieces are getting higher and higher. The thin material (the thinnest is 0.03 ± 0.002mm) The choice of mold clearance has become a very prominent issue in the instrumentation industry. Since the 1950s, many factories use the blanking clearance values set by the Soviet Union, with relatively small values. In the 1960s, after using a large gap in some domestic units, the quality of blanking pieces and mold life have been greatly improved, and the large gap has gradually been pushed in China
