钢模具的质量怎样鉴别
How to Identify the Quality of Steel Mould
检查井钢模具形状复杂,精度要求高,制造周期长,模具的加工费远远超过模具的材料费用,这种模具也应采用高性能的材料制造.高应力的模具采用高性能的材料制造,并可用廉价的表面强化技术提高其耐用度.零件产量不大的模具,形状简单、应力小、容易制造的模具,经常改形的模具,可用普通钢、铸铁甚至非金属制造.检查井钢模具装备行业的发展促进了模具工业的进步,模具工业的发展也给加工设备提出了更多的要求
The die for checking well steel has complex shape, high precision requirement, long manufacturing cycle, and the processing cost of the die far exceeds the material cost of the die. The die for checking well steel should also be manufactured with high performance material. The die for high stress should be manufactured with high performance material, and the durability of the die can be improved with low cost surface strengthening technology. Moulds with simple shape, small stress, easy to manufacture and often modified can be manufactured with ordinary steel, cast iron or even non-metal. The development of inspection well steel mould equipment industry promotes the progress of mould industry, and the development of mould industry also puts forward more requirements for processing equipment.
