The punch punch in the stamping die accessories plays an important role in the processing of the product. Therefore, a well-designed punch is an indispensable part of the stamping die. So, what are the requirements for the shape of the punch design?

1. Try to avoid rectangular punches, because rectangular punches are easy to skip waste.

2. The punch should avoid excessively long cantilevers and slots. Because the cantilever will affect the strength of the punch. The slot will affect the strength of the die. Try to avoid sharp corners of the punch.

3. The punch should be made of anti-stripping structure, and considering the processing technology, try to use grinder and wire cutting processing to reduce electrical discharge processing.

4. There will be an interface at the joint of the two punches. The inner hexagonal punch should minimize the size, position and shape of the punch interface position on the product under the condition of ensuring smooth punching. It should be negotiated and formulated with the customer.

As an important connector mold part in the mold, the quality of the hexagonal punch of the punching pin affects the normal work of the mold. When working, the cemented carbide punching pin plays an important role in enhancing the strength of the thimble and preventing the deformation and bending of the thimble. According to materials, shapes and uses, the punches include SKD, SKH, ASP punches, guide punches, ejector punches, tooth punches, detection heads, hexagonal socket punches, oval needles, forming punches, Fan-shaped punches, special-shaped punches, high-speed steel punches and high-quality carbide punches. Plum blossom punch Among them, high-quality cemented carbide punches are also called tungsten carbide punches.

In our plum blossom punch processing and production process, according to the different needs of our orders, the cemented carbide punches we use also have different shapes, and the holes are processed in batches. For example, computer cases are cold holes, and many electrical appliances, milling machines, and drilling machines can only process round holes. Hexagon socket punch, while punching, can process hundreds of holes at the same time. When working, the distance between the punch and the die is very close. This is to prevent the punch from sticking to the die. The gap also depends on the thickness of the material. Thick materials require a large gap. In addition, the gap also depends on the thickness of the material. Because of the hardness of our workpieces.
