Characteristics of Precision Stamping

Characteristics of precision stamping.

Precision stamping is a strong edge pressing precision punching. Its process principle is: on a three-action press, with the help of a special structure of precision punching die, under strong force, the material is plastic, sheared, and deformed, thereby obtaining high-quality precision stamping parts.

Precision stamping has the following characteristics:

1. Precision stamping is jointly acted by three forces (punching force, edge pressing force, and anti-top force). The punching gap between the convex and concave dies is only 0.5% of the material thickness, which is 1/10 of the ordinary stamping gap.

2. Precision stamping has the advantages of smooth punching surface, high dimensional accuracy, and high flatness. After deburring, it can be directly assembled without the need for cutting, grinding, straightening, and other processing steps required after ordinary stamping, saving a lot of investment in auxiliary equipment and manpower, material resources, and operating costs. It not only improves production efficiency, but more importantly, avoids the loss of precision in each process, and ensures the repetitive accuracy and production reliability of mass-produced parts.

3. The main application area of precision stamping is automotive parts. The modern automobile industry enjoys all the performance advantages of fine blanking parts. There are at least 40 fine blanking parts in each car.
