The punch is used in conjunction with the punch rod, punch nut and punch nut. Generally used for punching in iron tower factories.
At present, the precision of punches produced by domestic professional manufacturers can reach ±0.002mm, which is at the international leading level.
In the cold stamping process, stamping dies process materials into parts. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. It is more common in industrial production. Stamping dies are process equipment for stamping production and are technology-intensive products. The quality, production efficiency and production cost of stamping parts are directly related to the precision and quality of mold design and mold parts.
The cemented carbide punch is used as a part of the stamping die when it is working, and is also called cemented carbide punch, which is a replaceable mold consumable product. Punching needles can be divided into SKD, SKH, ASP punching needles, guide punches, master punching needles, threading punching needles, detecting tips, hexagonal punching needles, elliptical punching needles, forming punching needles, according to different materials, shapes and uses. Fan-shaped punches, special-shaped punches, high-speed steel punches and high-quality carbide punches are also used to call tungsten steel punches in Guangdong.
Cemented carbide punches used in stamping dies in industrial production can produce punch rods of different shapes according to the different needs of products, and carry out batch hole processing. Especially in the production of progressive mold sets, such as computer cases, there are many heat dissipation holes on them, mobile phones, many electrical appliances, and machinery. Ordinary drilling machines, or lathes, milling machines, only It can process round holes, and when punching, a large punch press can process hundreds of holes at the same time.
