本文对标准件行业应用量多面广的冷镦凹摸的服役条件及失效形式进行了研究分析后,指出该类模具要求高的耐磨性与足够的冲击韧性以及400—500℃的红硬性。尔后,在高温回火过程同时复合真空氧氮化,获得了理想的组织与优异的性能,并具有优质、高效、节能、低温、微变形、无公害等优点,使××厂的冷镦凹模使用寿命提高1—3倍。取得了明显的经济效益。 After the research and analysis on service conditions and failure modes of the cold forging industry with a wide range of applications in the standard parts industry, it is pointed out that such molds require high wear resistance, sufficient impact toughness and red hardness of 400-500 ° C. Then, at the same time the high-temperature tempering process composite vacuum nitriding, access to the ideal organization and excellent performance, and has the advantages of high quality, high efficiency, energy saving, low temperature, micro deformation, pollution-free, Die service life increased 1-3 times. Obtain obvious economic benefits.
