我厂自一九五八年生产以来,在模具热处理方面作了一些工作,有戌功的也有,失败的,从模具热处理存在的貭量问题来看,目前变形是主要的,我们发现不同的模具变形规律不一致。但对于一些形状相仿者,热处理变形基本上具有同类型的变形,变形的方式大致有无方向性变形(扭曲),有方向变形,椭圆变形,均匀的变形(丙孔缩小或胀大)等。通过这几年的模索,模具热处理貭量有了提高,由于水平所限,就个人感受
Since our factory produced in 1958, we have done some work in mold heat treatment. There are also some failures in the mold heat treatment. Judging from the existing problems of mold heat treatment, the current deformation is the main one. We found that different Die deformation is inconsistent. However, for some similar shapes, the heat treatment deformation basically has the same type of deformation, and the deformation method generally has no directional deformation (distortion), directional deformation, elliptical deformation, uniform deformation (reduced or expanded propofol), and the like. Through the mold of the past few years, mold heat treatment has increased the amount of measurement, due to the level of personal feelings
