模具的制造通常是由钳工进行,质量和效率都很低, 往往跟不上生产的需要。我厂从1957年初开展模其制造钳工机械化以后,采用了成形磨削来制造冲头和拼块凹模,使我厂在模具制造上形成了新的转折点,改变了模具制造的面貌。根据两年多的使用证明,利用成形磨削在很大程度上消除了过去模具制造上的弊病。采用成形磨削制造模具有三个优点:1)消除了零件因热处理变形而无法修正所造成的废品;2)保证了模具的质量(一般尺寸精度可达2级,表面光洁度可达8),同时提
Mold manufacturing is usually carried out by fitter, the quality and efficiency are very low, often can not keep up with the production needs. Since the beginning of 1957, our factory has carried out the mechanization of the manufacture of fitter workers, and has used the forming grinding to make the punch and the concave die, which made our factory make a new turning point in the mold making and changed the appearance of the mold making. According to more than two years of use proved that the use of forming grinding to a large extent eliminates the shortcomings of the mold manufacturing. The use of forming grinding mold has three advantages: 1) eliminate the parts due to heat treatment deformation can not be caused by the amendment of the waste; 2) to ensure the quality of the mold (general dimensional accuracy of up to 2, the surface finish up to 8), at the same time mention
