Understand the classification of tungsten carbide punch die

Tungsten carbide die: cold heading die, cold punch die, drawing die, hexagonal die, screw die and so on.  Today we focus on the classification of cold stamping die (also known as stamping die) in hard alloy die.  Its classification is many, mainly according to the process nature, mold structure, mold material three aspects.  According to the classification of process properties, it is divided into punching die, bending die, drawing die, forming die, riveting die;  According to the classification of process combination degree, stamping die can be divided into single process die, compound die, progressive die, transfer die four categories;  According to the different processing methods of products, cold stamping die can be divided into punching and shearing die, bending tool, pumping die, forming die and compression die.  

Today we have a specific understanding of the five categories of stamping die according to the nature of the process.  

1, blanking die: along the closed or open contour line to separate the material of the die.  Such as blanking die, punching die, cutting die, cutting die, cutting die, etc.  

2, bending die: make blank sheet or other blank along a straight line (bending line) bending deformation, so as to obtain a certain Angle and shape of the workpiece die.  

3, deep drawing die: is the blank into open hollow parts, or hollow parts to further change the shape and size of the mold.  

4, forming die: is the blank or semi-finished workpiece according to convex, concave die shape directly copy forming, and the material itself only produce local plastic deformation of the die.  Such as bulging die, shrinkage die, flaring die, undulating forming die, flanging die, plastic die and so on.  

5, riveting die: is to borrow external forces to participate in the parts in a certain order and way to connect or lap together, and then form a whole.  

For more information on the other two categories of cold stamping die, please look forward to the next installment.  Process property is one of the important factors affecting the quality of stamping die, it is particularly important to choose an enterprise with rich processing and production experience.  Zhuzhou Jinxin is a one-stop customized cemented carbide production service provider, cemented carbide mold is one of the company's main industries, is a manufacturer of cemented carbide raw materials, its own cemented carbide non-standard parts processing customized factory, cooperation with cemented carbide related universities, with special production and processing technology and cemented carbide formula.
