冷作模具钢是在常温下对材料进行压力加工或其他加工所使用的模具，根据制造和使用要求合理地选择冷作模具材料更重要。那么下面就来讲讲冷作模具钢材料的使用性能要求内容吧。

Cold working die steel is a die used for pressure processing or other processing of materials at room temperature. It is more important to reasonably select cold working die materials according to manufacturing and use requirements. Now let's talk about the performance requirements of cold work die steel materials.

⑴冲裁模具钢性能的要求

(1) requirements for properties of blanking die steel

①冲裁模的正常失效形式主要是磨损，经过一段时间的使用，刃口会逐渐变得圆钝。当磨损到一定程度，冲裁件则产生毛刺而影响制件质量。

① The normal failure form of blanking dies is mainly wear. After a period of use, the cutting edge will gradually become blunt. When worn to a certain extent, the blanking parts will produce burrs and affect the quality of the parts.

②冲裁模具用钢的主要性能要求应满足高硬度和高耐磨性；应具有足够的抗压和抗弯强度，同时应具有适当的韧性。

② The main performance requirements of steel for blanking die should meet the requirements of high hardness and high wear resistance; It shall have sufficient compressive and flexural strength and appropriate toughness.

⑵冷礅模具钢性能的要求

(2) requirements for properties of cold abutment die steel

①冷镦模的主要失效形式是：凸、凹模工作表面的磨损擦伤、凸模折断、凹模开裂、凸模镦粗而凹模模口胀大和棱角堆塌等。

① The main failure forms of cold upsetting die are: wear and scratch of the working surface of punch and die, punch breaking, die cracking, punch upsetting and die mouth swelling and edge collapse of die, etc.

②鉴于冷镦模的工作条件恶劣，要求其要有足够的硬度。在通常情况下，凸模的硬度为60～62HRC，凹模的硬度为58～60HRC。

② In view of the poor working conditions of the cold heading die, it is first required to have sufficient hardness. Under normal circumstances, the hardness of punch is 60 ~ 62Hrc, and that of die is 58 ~ 60HRC.

⑶冷拔模具与成型模具钢性能的要求

(3) requirements for the properties of cold drawing die and forming die steel

①成型模具的主要失效形式是磨损，而拉拔模具除了严重的磨损以外，还会产生胶合现象。

① The main failure form of forming die is wear, and the drawing die will produce gluing phenomenon in addition to serious wear.

②拉拔模的性能要求主要是具有较高的耐磨性，凸模硬度一般要求是58～62HRC，凹模硬度要求是62～64HRC，并且还要求具有良好的抗咬合性。成型模具的耐磨性要求比较低，通常凸模的硬度为54～58HRC，凹模的硬度为56～60HRC，但要求韧性较高。

② The performance requirements of the drawing die are mainly high wear resistance. The hardness of the punch is generally required to be 58 ~ 62Hrc, and the hardness of the die is required to be 62 ~ 64hrc, and it is also required to have good bite resistance. The wear resistance requirements of forming dies are relatively low. Generally, the hardness of male dies is 54 ~ 58hrc, and the hardness of female dies is 56 ~ 60HRC, but the toughness is required to be high.
