我厂过去用的下料模刃口,全部用高级合金工具钢制造,价昂且缺,加工工序又多,从锻坯到精磨完成,要经过十道工序。采用堆焊工艺以后,情况就不同了。它既不要大锻锤和大面积高温盐浴炉,又不需要使用昂贵的高级合金工具钢,工序亦从原来整体刀口的十道工序减少到六道工序,材料、工时都大大节约,而刃口的质量,经过实践证明,与高级合金工具钢相仿。模具堆焊就是以普通碳素结构钢为基体,在刃口部份堆焊一层特种焊料作为刃口,以达到模具使用的质量和性能要求。如 I used to use the cutting die cutting edge, all with advanced alloy tool steel, expensive and lack of processing processes and more from the forging to the grinding is completed, to go through ten processes. After the surfacing process, the situation is different. It does not require forging hammer and large-area high-temperature salt bath furnace, and does not require the use of expensive high-alloy tool steel, the process is also reduced from the original overall blade of 10 processes to six processes, materials, man-hours are greatly saving, and edge The quality, proven by practice, is similar to the high alloy tool steel. Die surfacing is based on ordinary carbon steel as a substrate, the edge part of the surfacing a layer of special solder as a cutting edge, in order to achieve the quality and performance requirements of the mold. Such as
