Definition of precision hardware stamping parts: refers to a type of handicraft that uses a punch and mold to deform or fracture stainless steel, iron, aluminum, copper, and other plates and dissimilar materials to achieve a certain shape and size.

There are various names for precision metal stamping, sometimes also known as sheet metal forming, but there are slight differences. Plate forming is carried out using raw materials such as plates, thin-walled tubes, and thin profiles. The forming method of plastic processing is collectively referred to as sheet metal forming, and at this time, the deformation in the direction of the thick plate is generally not emphasized.

The precautions for processing common precision hardware stamping parts should be mainly discussed from the following aspects:

1、 In daily processing, precision hardware stamping parts may encounter problems such as oversized or undersized punching holes, as well as significant differences from punch sizes;

2、 When the cutting edge is worn, the tensile stress on the material increases, and the tendency of precision hardware stamping parts to flip and twist increases. When flipping occurs, the size of the punching hole tends to decrease;

3、 The processing of precision metal stamping parts exerts strong pressure on the material, causing plastic deformation of the material, which can lead to a larger punching size. However, when reducing strong pressure, the punching size will decrease;

4、 The shape of the end of the convex die blade. If the end is trimmed with an inclined or curved surface, the stamping force slows down, making it difficult for the stamping part to flip or twist;

Precision metal stamping parts processing is one of the main methods of metal plastic processing, and stamping parts are used in various mechanical equipment, so it is necessary to ensure the processing quality of metal stamping parts.

Therefore, during the processing process, we need to strictly follow the above principles and standardize operations to ensure the quality of the processed products. The above content is timely and concise. If you need to solve specific problems, please consult professionals.
