The performance of the progressive die is closely related to the material used

In the stamping process, the progressive die is often used. If you want to play the role of the progressive die, you need to master its basic knowledge. Especially when selecting, you should choose a progressive die with good performance. There are many factors that affect the performance of the progressive die. Today we will focus on explaining the close relationship between the performance of the progressive die and the materials used.　　 1. Hardness.　　Hardness is one of the important indicators for testing the performance of progressive molds. Generally, the hardness cannot be too low. To obtain high hardness, you need to select the appropriate steel and undergo heat treatment processes such as quenching and tempering. In order to ensure that its hardness remains above 60HRC, the carbon content in the material cannot be too low.　　 2. Impact performance.　　 When the material used in the progressive die will have certain resistance to cracks under impact load, this feature is also called toughness. Toughness is a main basis for judging whether the progressive die is easy to break. Generally speaking, the low carbon content in steel has good toughness, but after heat treatment, the hardness will become higher.　　 3. Bending resistance.　　 Flexural performance is also the flexural strength. Generally speaking, progressive dies should be selected with high flexural strength. Usually steel materials have strong flexural strength, while high-carbon and low-alloy steels have slightly worse strength after reading.　　The material of progressive die is often closely related to the material used, but it does not mean that the more expensive the material used, the better the progressive die produced. It mainly depends on whether the material is suitable.　　Through the above introduction, we can know that in order to ensure the quality of progressive die, the manufacturer should work hard on the production materials.
