Advantages of stamping

Compared with other methods of mechanical processing and plastic processing, stamping has many unique advantages in both technical and economic aspects. The main performance is as follows.

1. Punching processing has high production efficiency, convenient operation, and easy to realize mechanization and automation. This is because punching depends on the die and punching equipment to complete the process. The stroke times of ordinary presses can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute. May get a punch.

2. During stamping, the die guarantees the size and shape accuracy of the stamping part, and generally does not damage the surface quality of the stamping part, and the life of the die is generally longer. Therefore, the stamping quality is stable, the interchangeability is good, and it has the same shape. feature.

3. Stamping can process parts with a wide range of sizes and complex shapes, such as small watches and stopwatches, as well as automobile side members and covers, etc., plus the cold deformation and hardening effect of the material during stamping, and the strength and stiffness of stamping. Both are higher.

4. Generally speaking, there is no chip and scrap generated in stamping, the material consumption is less, and no other heating equipment is needed. Therefore, it is a material-saving and energy-saving processing method, and the cost of stamping parts is low.

Stamping design principles

1. The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.

2. The designed stamping parts must be beneficial to improve the utilization rate of metal materials, reduce the variety and specifications of materials, and reduce the consumption of materials as much as possible. When possible, use low-cost materials to make parts as waste-free and waste-free as possible.

3. The designed stamping parts must be simple in shape and reasonable in structure, which is conducive to simplifying the mold structure and simplifying the number of processes. That is, the minimum and simplest stamping process is used to complete the processing of the entire part, which is reduced and processed by other methods. Operation is convenient for the organization to realize mechanization and automated production to improve labor productivity.

4. Under the condition of ensuring normal use of stamping parts, the dimensional accuracy level and surface roughness level should be as low as possible, which is conducive to the interchange of products, reducing waste products and ensuring stable product quality.

5. The design of stamping parts should be conducive to the use of existing equipment, process equipment and process as much as possible, and it will be beneficial to the extension of the service life of the die.
