1.挤压金属模必须具备的材料特性热处理不仅在于发挥冷挤压模的特性,而且要发挥所用材料的特性,使之能够在各种条件下使用,热处理这一工艺对能否发挥这一特性起着十分重要的作用。由于热处理作业是加热、冷却这种简单的工艺操作的复合,因此,只要按各种材料所规定的标准热处理条件进行操作,而不出大的故障,就能得到所要求的硬度,从而达到提高耐磨性的目的。以挤压模为例,如果考虑其使用条件,由于操作时要反复承受压缩、弯曲和摩
1. extrusion die must have the material properties of heat treatment is not only to play the characteristics of cold extrusion die, but also to play the characteristics of the material used, so that it can be used under various conditions, heat treatment of this process can play this Features play a very important role. Since heat treatment is a combination of heating and cooling which are simple process operations, the required hardness can be achieved as long as the heat treatment is performed under the standard heat treatment conditions specified for the various materials so as to achieve an improvement The purpose of wear resistance. To die as an example, if you consider the conditions of use, due to the operation to be repeatedly subjected to compression, bending and friction
