摘要
模具材料作为制造模具的基础,它的性能和热处理工艺对模具寿命有着决定性的影响。冷作模具性能要求包括耐磨性、韧性、强度、抗疲劳性能和抗咬合性。冷作模具材料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。冷作模具钢按成分和性能可分为碳素工具钢、高碳低合金钢、高耐磨模具钢、高速钢、基体钢、无磁模具钢、硬质合金及钢结硬质合金。合理地选用冷作模具材料并进行精确的成形加工和适当的热处理,能够有效的提高模具使用寿命。
Mold materials as the basis for production molds,its performance and heat treatment process on the die life have a decisive impact.Cold mold performance requirements including wear resistance,toughness,strength,anti-fatigue and anti-bite nature.Cold mold material properties of heat treatment process include： hardenability,hardened resistance,tempered nature,thermal sensitivity,oxidation of decarbonization trend,quenching deformation and crack orientation.Cold die steel can be classified according to composition and performance of carbon tool steel,high carbon low-alloy steel,high wear-resistant die steel,high-speed steel substrate steel,non-magnetic die steel,cemented carbide and steel bond hard alloy.A reasonable selection of cold-working die materials,and forming a precise and appropriate heat treatment,can effectively improve the life of mold.
