punch

Detailed introduction:

Punch is also called convex die, upper die, Yang die, punch, etc., and the punch is divided into A-type punch, T-type punch, shaped punch.

Punch is a metal part installed on the stamping mould, applied to direct contact with the material, make the material deformation, cut the material.

Mould punches generally use high-speed steel and tungsten steel as the material, there are high-speed steel punches and tungsten steel punches, etc., and high-speed steel is the most commonly used material, commonly used CR12, CR12MOV, asp23, skd11, skd51, skd61, etc., tungsten steel material is generally used in the higher requirements of the punching and shearing moulds.

Relevant knowledge about stamping processing method.

Punch is used together with punch rod, punch nut and punch nut. Generally used in tower factory punching purposes.

At present, the domestic professional manufacturers of punches can reach the accuracy of ± 0.002mm, ranking in the international leading level.

Stamping mould in the cold stamping process, the material will be processed into parts. Stamping is at room temperature, the use of moulds installed in the press to exert pressure on the material, so that it produces separation or plastic deformation, so as to obtain the required parts of a pressure processing method, more common in industrial production. Stamping mould is the process equipment for stamping production, which is a technology-intensive product. The quality, production efficiency and production cost of stamped parts are directly related to the quality of mould design and precision of mould parts.

Carbide punches, as the working parts of stamping moulds, are also called carbide punching rods, which belong to the category of replaceable mould consumables. Punch according to the material, shape, use of different can be divided into SKD, SKH, ASP punches, guide punch, mother punch, tooth punch, checking tip, hexagonal punch, elliptic punch, moulding punch, fan punch, shaped punch, high-speed steel punch and high-quality requirements of the cemented carbide punch rod, Guangdong side is also used to be called tungsten steel punch.

The tungsten carbide punches used in stamping moulds in industrial production can be made into different shapes of punching rods for batch hole processing according to the different demands of products. Especially in the progressive mould set production operations, such as computer chassis, there are a lot of cooling holes, and mobile phones, many electrical appliances, machinery will be used above, ordinary drilling machine, or car, milling machine processing, can only be processed out of the round holes, and stamping, large punching machine, while processing hundreds of holes.
