如何延长模具使用寿命,减少模具钢消耗,这是锻压行业面临的一个课题,天津拖拉机厂锻造分厂经过大胆探索、创新,把双金属堆焊技术应用在模具制造和修复上,使企业获得较好的经济效益,使我国双金堆焊属技术跨入世界先进行列。一、双金属堆焊技术的应用范围1.常规用于制造切边模、冲孔模、落料模的单一模具材料,改为双金属堆焊材料,例如常用的8Cr3、Cr12Mo、5CrMnMo,5CrNiMo 等模具材料,可改用基体为碳钢、或碳工具钢,在模具工作部位——刃口
How to extend the service life of molds and reduce the consumption of mold steel, which is a subject facing the forging industry. After extensive exploration and innovation in the tractor factory in Tianjin, the bimetallic surfacing technology is applied to mold making and repairing so that the enterprises can get more Good economic benefits, so that our country double gold welding technology into the world advanced ranks. First, the application of bimetal welding technology 1. Conventionally used in the manufacture of trimming die, punching die, blanking die a single die material, to bimetallic surfacing materials, such as commonly used 8Cr3, Cr12Mo, 5CrMnMo, 5CrNiMo Such as mold materials, can be converted to carbon steel substrate, or carbon tool steel, working parts in the mold - the edge
