Custom Tungsten Carbide Alloy Punch Rod Making From Solid Carbide Rod

Cemented carbide punch rod is tungsten steel punch rod, also known as carbide punch, punch needle or punch, is installed in the punching die for continuous punching punching and punching operations, so that the processed materials occur separation or plastic deformation, so as to obtain the required finished products or semi-finished products.

The cemented carbide produced by powder metallurgy process has become the teeth of modern industry because of its high hardness, high strength, high wear resistance and corrosion resistance. Tool products based on cemented carbide materials are powerful tools for manufacturing industry, especially the core of some working environment requirements. The working parts are more important for the use of cemented carbide products.

Taking the punch rod used most frequently in batch production of progressive die as an example, the carbide punch rod is the core component. The carbide punching rod is a tungsten steel punching rod, also known as punch, punch or punch, is installed on the punching die for continuous punching punching and punching operations, so that the processed materials occur separation or plastic deformation, so as to obtain the required finished products or semi-finished products. Cemented carbide punch rods are specially selected by the pharmaceutical industry for their acid, alkali, corrosion and rust resistance.

Application:

According to different stamping materials, different stamping dies are designed, basically through a multi-step stamping process to complete a product or semi-finished work. The shapes and specifications of the carbide punch rods required by different steps are different, so the special-shaped punch needles for matching stamping dies are designed and customized. According to the different shapes and different uses, cemented carbide special-shaped stick can be divided into:

1. Guide punch is also called guide punch for short, according to the needs of the punch can have a variety of shapes, A-type B-type HB-type TAPP T ** P type and so on.

2. Mother-in-law punch is also called Mother-in-law punch, which is called Mother-in-law punch for short. There is a small protrusion at the top of the punch. I don't know the origin of the name, maybe because of the protrusion at the top of the punch. Letter punching needle can be divided into standard A type JS** type and so on.

3. There are dental punch, inspection tip, hexagonal punch, elliptical punch, forming punch, fan punch, special-shaped punch, high-speed steel punch, carbide punch and so on.

Operating Requirement:

Precision die matching with the use of carbide punch bar precision requirements, as well as product consistency, requiring batch production of each type of punch bar in accordance with dimensional accuracy tolerance requirements, to achieve maximum die life. The consistency of the product is also critical as a cemented carbide rod used as a mold.

The work of stamping dies is continuous, and the service life requirements of the rods become the focus. According to the different materials and thickness of the carbide punch rod, different alloy materials should be selected. Generally speaking, the thicker the product is punched, the lower the hardness and the better the toughness of the carbide is. The harder the material is, the harder the carbide will be, and the harder the carbide will be, the more effective it will be to avoid punching needles. And stamping thin sheet metal, or hardness is not high, the hole processing of this product, carbide punching rod can use harder, so you can improve the life of the punch needle.
