摘要
冷作模具钢工作时承受压缩、拉伸、弯曲、冲击、摩擦等很大的变形抗力,它的性能和热处理工艺对模具寿命有着决定性的影响。其使用性能主要包括耐磨性、韧性、强度、抗疲劳性能和抗咬合性,热处理工艺性能主要包括:淬透性,淬硬性,耐回火性,过热敏感性,氧化脱碳倾向,淬火变形和开裂倾向等。冷作模具钢的力学性能、工艺性能和承载能力进行分组,使其具有更合理的适用范围来选用冷作模具钢,从而能够有效的提高冷作模具使用寿命。
Cold-working die steel under compression, tensile, bending, impact, friction and mechanical force in the using. Its performance and heat treatment process has a decisive influence on the service life of die. Its performance mainly includes the wear resistance, toughness, strength, fatigue resistance and seizure resistance, heat treatment pegrormance mainly includes: hardenability, hardening, tempering resistance, overheating sensitivity, oxidation and decarburization tendency, quenching deformation and cracking tendency. Grouping according to mechanical behavior ,process performance and bearing capacity of Cold-working die steel mechanical. Which has applied more reasonable and rational selection of Cold-working die steel, it can effective improve the service life of die.
