Punch Rod Made Of Tungsten Carbide Alloy Material For Stamping Battery

The tungsten 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 tungsten carbide 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.

The conventional physical parameters of the hard alloy rod are as follows:

1, CO content: 10%-20%.

2, density g/cm3:14.0 to 14.5.

3, hardness: 87-92.0HRA.

4, grain size: 0.6-1.2um.

5, bending strength: 4000MPa.

6, elastic modulus GPa:490.

7. The coefficient of thermal expansion is 10-6/0C:5.4.

8, the size and specification of the carbide rod shall be customized according to the drawing, and the accuracy requirement will reach + 0.001.

Use In Stamping Die:

Stamping dies are processed into parts in cold stamping. Stamping is a kind of pressing method that applies pressure on material by means of a die mounted on a press at room temperature to produce separation or plastic deformation, so as to obtain the required parts. It is quite common in industrial production. Stamping die is the process equipment for stamping production, and it is a technology intensive product. The quality, production efficiency and production cost of stamping parts are directly related to die design and precision quality of die parts.

As a part of stamping die, cemented carbide stamping rod belongs to the replacement of mold consumables. Punching needles can be divided into SKD, SKH, ASP, guide, mother-child, tooth-pulling, inspection tip, hexagonal, elliptical, forming, fan-shaped, special-shaped, high-speed steel and high-quality carbide punches according to their materials, shapes and uses. Steel punching needle.

The carbide punch rods used in the stamping die in industrial production can be manufactured with different shapes according to the different requirements of the products, and the holes can be processed in batches. Especially in the production of progressive die sets, such as computer chassis, there are many radiation holes above, as well as mobile phones, many electrical appliances, machinery will be used above, ordinary drilling machine, or turning, milling machine processing, can only process circular holes, the efficiency is very low. While punching, large-scale punching machine, while processing hundreds of holes in just a few seconds, the scale of production efficiency has been significantly improved. Especially in the mass production of automatic precision machine tools, the precision and quality of the parts produced by stamping are greatly improved.
