近几年来,我们在用户的配合下,对一些早期失效的模具进行了分析,改进了工艺,初步解决了几种模具早期损坏的问题,并提高了模具使用寿命。我们把这种改进工艺提高模具使用寿命的工艺方法称强韧化处理。现将几种模具工艺的改进介绍如下。 GCr15粉末冶金压模“提高淬火温度”这种模具形状较简单,凹模为圆筒形,凸模为圆柱形,凹模断面壁厚从4毫米到50毫米不等。模具是在400吨压力机下工作,模具工作面与铁粉
In recent years, with the cooperation of users, we have analyzed some molds that have failed earlier, improved the process, and initially solved several problems of early mold damage and improved the service life of molds. We improve the process to improve the service life of the mold called toughening process. Now several improvements in mold technology are described below. GCr15 powder metallurgy die “to increase the quenching temperature” This mold shape is simple, the die is cylindrical, punch is cylindrical, die section wall thickness ranging from 4 mm to 50 mm. The mold is working under 400 tons of press, the mold face and iron powder
