冷作模具钢在工作时由于材料的变形抗力比较大，模具的工作部分承受很大的压力、弯曲力、冲击力及摩擦力，导致冷作模具钢出现磨损或因断裂、崩力和变形超差而失效。下面来讲讲冷作模具钢的工作条件及性能要求。

The cold working die steel is worn out or fails due to fracture, collapse force and deformation out of tolerance due to the large deformation resistance of the material and the large pressure, bending force, impact force and friction force on the working part of the die. Now let's talk about the working conditions and performance requirements of cold working die steel.

冷作模具的性能要求：

Performance requirements of cold working die:

1、高硬度和高耐磨性，工作时保持锋利的刃口。

1. High hardness and wear resistance, keep sharp edges when working.

2、较高的强度和韧性及一定的热硬性，工作时刃部不易崩裂或塌陷。

2. With high strength, toughness and certain thermal hardness, the blade is not easy to crack or collapse when working.

3、较好的淬透性，保证淬火态有较高的硬度和一定的淬透深度。

3. Good hardenability ensures high hardness and certain hardenability depth in quenched state.

4、较好的加工工艺性和成形性，较好的淬火性，热处理变形小，在复杂断面上不易淬裂。

4. Good processability and formability, good quenching safety, small heat treatment deformation, and not easy to crack on complex sections.

冷作模具钢具有高的硬度和耐磨性、高的抗弯强度和足够的韧性，这样才能保证冲压过程的顺利进行。由于其工作时需要承受冲压力，则还需要具有高的耐磨性能，又由于形状复杂易于产生应力集中，所以要求具有较高的韧性；表示模具尺寸大、形状复杂.则要求较高的淬透性、较小的变形及开裂倾向性。

Cold working die steel has high hardness and wear resistance, high bending strength and sufficient toughness, so as to ensure the smooth progress of the stamping process. Because it needs to bear the impact pressure when working, it also needs to have high wear resistance, and because the shape is complex, it is easy to produce stress concentration, so it is required to have high toughness; It means that the mold is large in size and complex in shape. It requires high hardenability, small deformation and cracking tendency.

合理选取模具材料及实施正确的热处理工艺是保证模具寿命的关键。模具材料的选用和相应的热处理工艺是重要因素。据资料显示，在所有的模具失效因素中，模具的材料和热处理约占70%的比例，成为影响模具寿命的主要因素。因此在模具的整个设计制造过程中，模具材料的选用和热处理工艺是否适当显得尤为重要。更多相关信息就来我们网站https://www.jnqhmj.com咨询吧。

Reasonable selection of mold materials and implementation of correct heat treatment process are the key to ensure the service life of the mold. The selection of die materials and the corresponding heat treatment process are important factors. According to the data, among all the die failure factors, the die material and heat treatment account for about 70%, which has become the main factor affecting the die life. Therefore, in the whole process of mold design and manufacturing, the selection of mold materials and whether the heat treatment process is appropriate is particularly important.
