Carbide punch needle is one of the commonly used punches in the mass production operation of progressive stamping dies, carbide punch needle is tungsten carbide punch needle, also known as carbide pins, punch bar or punch, is installed in the stamping die for continuous punching stamping punching operation to make the processed material separation or plastic deformation to obtain the required finished or semi-finished mold parts.
Tungsten carbide punch needles have excellent properties such as acid and alkali resistance, corrosion resistance, abrasion resistance and rust resistance, which are specially selected by the pharmaceutical industry to make punches for stamping tablets. Stamping is a processing method that uses a die mounted on a press to apply pressure to the material at room temperature to produce separation or plastic deformation to obtain the required parts, which is more common in industrial production. Stamping dies are essential process equipment for stamping production and are technology-intensive products. The quality of the stamped parts, the production efficiency and the production cost are directly related to the die design and the quality of the precision of the die parts, etc.
As a core part of the stamping die, the punch needle is a replaceable consumable product. For demanding stamping workpiece must use tungsten carbide punching needle, generally use tungsten steel with hardness below 90 and above 80, if use other material punching needle is easy to wear. The next key is the gap of the convex and concave die can be enlarged as much as possible, in order to reduce the resistance of the punch. The focus of the custom-made carbide punch needle is the accuracy and consistency of the product.
