The classification of stamping dies(1)
Carbide dies include: cold heading dies, cold punching dies, drawing dies, hexagonal dies, spiral dies, etc. Today, we will focus on the classification of cold punching dies (also called stamping dies) in carbide dies. There are many ways to classify them, mainly according to three aspects: process nature, die structure and die material. According to the classification of process nature, it is divided into punching die, bending die, stretching die, forming die and riveting die; according to the classification of process combination, stamping dies can be divided into four categories: single process die, compound die, progressive die and transfer die; according to the different processing methods of products, cold punching dies can be divided into five categories: punching and shearing die, bending tool, extraction die, forming die and compression die.
Today, we know the five categories of stamping dies according to the nature of the process.
1, Punching die: A die that separates materials along a closed or open contour line. Such as drop die, punching die, cutting die, notching die, cutting edge die, cutting die, etc.
2, Bending die: make the slab blank or other blanks along the straight line (bending line) to produce bending deformation, so as to obtain a certain angle and shape of the workpiece of the mold.
3, Drawing die: It is the mold to make the sheet blank into open hollow parts, or make the hollow parts further change the shape and size.
4, Forming die: It is a die that directly replicates the shape of the blank or semi-finished workpiece according to the convex and concave die, and the material itself only produces local plastic deformation. Such as expansion die, indentation die, flaring die, undulation forming die, flanging die, shaping die, etc.
5, Riveting die: it is to borrow external force to make the participating parts connected or lapped together in a certain order and way, and then form a whole.
If you want to know the other two classifications of cold punching dies, please look forward to the next issue. The nature of the process is one of the most important factors affecting the quality of the stamping dies, and it is especially important to choose a company that is experienced in processing and production. Zhuzhou Jinxin is a one-stop carbide production and customization service provider, carbide die is one of the main industries of the company, is a carbide raw material manufacturer, has its own carbide non-standard parts processing and customization factory, and cooperates with carbide related colleges and universities, has special production processing technology and carbide formula.
