承垫式锻模错移的检查,原来多采用灌铅、灌蜡的方法,但是铅和蜡的收缩率较大,所以错移量在0.3～0.4毫米时,不易检查出。自1964年起,我们用胶塑剂压样法来检查这种锻模的错移量,解决了上述问题。 Shock-forging die shift inspection, the original use of more irrigation lead, wax filling method, but lead and wax shrinkage, so the wrong shift in 0.3 to 0.4 mm, not easy to check out. Since 1964, we used the plastic-plastic sample pressure method to check the wrong amount of forging die to solve the above problems.
