冷作模具钢的选材
Material selection of cold working die steel
1、工作时受力不大、形状简单、尺寸较小的模具,可用碳素工具钢制造。
1. The die with small stress, simple shape and small size can be made of carbon tool steel.
2、工作时受力一般、形状复杂或尺寸较大的模具,可用低合金工具钢(如9Mn2V、9SiCr、9CrWMl3、CrWMn、Cr2等)制造。
2. Molds with general stress, complex shape or large size can be made of low alloy tool steel (such as 9mn2v, 9SiCr, 9crwml3, CrWMn, CR2, etc.).
3、工作时受力大,要求高耐磨性、高淬透性、变形量小、形状复杂的模具,多用高碳高铬钢(Crl2、Crl2MoV等)制造。又发展了几种Crl2型钢的代用钢(如Cr6WV、Cr4W2MoV、Cr2Mn2SiWMoV等),另外,也可选用高速钢、低碳高速钢(6W6M05Cr4V等)和基体钢(化学成分相当于高速钢正常淬火后的基体成分的钢)来制造这类模具。
3. The molds with large stress, high wear resistance, high hardenability, small deformation and complex shape are usually made of high carbon and high chromium steel (Crl2, Crl2MoV, etc.). Several alternative steels for Crl2 type steels have been developed (such as cr6wv, Cr4W2MoV, cr2mn2siwmov, etc.). In addition, high-speed steel, low-carbon high-speed steel (6w6m05cr4v, etc.) and matrix steel (steel with chemical composition equivalent to the matrix composition after normal quenching of high-speed steel) can also be used to manufacture such dies.
4、在冲击条件工作,刃口单薄的模具,采用韧性较好的中碳合金工具钢(如4CrW2Si、6CrW2Si等)制造。
4. The die with thin edge working under impact condition is made of medium carbon alloy tool steel with good toughness (such as 4crw2si, 6CrW2Si, etc.).

Selection method:
冷作模具钢选用时需考虑加工方法、应力状态、成形加工对象的材料性质、生产数量、板材厚度等,此外模具的大小及尺寸精度也是不可忽略的因素。
When selecting cold work die steel, the processing method, stress state, material property of forming and processing object, production quantity, plate thickness, etc. shall be considered. In addition, the size and dimensional accuracy of the die are also non negligible factors.
负荷较小或小批量生产时使用低合金工具钢(SKS),负荷较大或大批量生产时使用冷作模具钢(SKD),负荷更大时选用高速工具钢及粉末高速工具钢。
Low alloy tool steel (sks) is used for low load or small batch production, cold working die steel (SKD) is used for high load or large batch production, and high-speed tool steel and powder high-speed tool steel are used for higher load.
适用于耐磨场合的有冷作模具钢、高速工具钢及高合金高速工具钢,适用于耐冲击场合的有8Cr-2Mo系模具钢和基体型高速工具钢。
Cold working die steel, high-speed tool steel and high alloy high-speed tool steel are suitable for wear-resistant occasions, and 8cr-2mo series die steel and base type high-speed tool steel are suitable for impact resistant occasions.
