The last time we have learned about the characteristics of cold-bump processing, today we have come to a deeper understanding of what the concept of roll forming is. Let's talk about the specifics of Xiaobian.
We need to know that there are two concepts for cold forming and local forming and forming. One is all the pressure, that is, there is force on the end face of the whole product. The second is partial pressure, that is, there is only pressure in the necessary part. Because of the large area of cold heading and high forming load, it requires a large tonnage press. For local molding, the necessary thickness variation can be obtained with a lower load, and it is widely used in forming holes and grooves. The above is the concept of rolling and forming. I hope to help everyone
