Stamping

In industrial production, parts of various materials and shapes are needed, and the production of these parts requires stamping processing. Stamping processing is the production technology of using conventional or special stamping equipment to directly subject the sheet metal to deformation force and deformation in the mold, so as to obtain product parts with a certain shape, size and performance. Stamping processing can be divided into precision stamping and Ordinary stamping.

Precision stamping is a material processing method developed on the basis of ordinary stamping technology. It is achieved by improving the guiding accuracy, reducing the gap between the convex and concave dies, increasing the reverse pressure and the v-ring blank holder. Under the condition of the three-dimensional compressive stress state, the process of precision stamping or precision stamping and other forming processes can be realized to obtain precision stamping parts.

Precision stamping requires higher precision of stamping parts. In the process of processing and production, when stamping coils or forming, it is necessary to consider the appropriate technical matching of precision punches, molds, materials, lubricants, etc., which requires higher requirements.

Ordinary stamping does not require high precision of stamping parts, but it also has its specific market needs. The thickness of the substrate is thicker and does not require cutting, cutting, stretching and other processes. The stamping materials are plates, pipes, etc., and the product order is required. When it is not too big, ordinary stamping can meet the requirements.
In the production process of precision stamping parts, when stamping coils or forming, it is necessary to consider the appropriate technical matching of precision punches, molds, materials, lubricants, etc.

The other applies a 25% main punching pressure to the end surface of the product’s stripper, which is called back pressure. These three pressures do not interfere with each other, and the size of each pressure is synchronized with the forming, and must be suitable for processing requirements such as forming and blanking, and can be adjusted arbitrarily. In addition, the processing speed must also be adjusted according to the required conditions of the processing object for forming or punching. The structure of the mold is not only required to be simple and light, but also suitable for use.

When processing thick plates, for molds that are prone to deformation, there is no significant deformation due to the use of central support. Even when the workpiece is squeezed into the die during the blanking process, if the ejector retreats, the inside of the die is also supported by the center support. If a hydraulic piston is connected to the side of the ring gear pressing plate and the piston moves backward, the inner side of the die ring pressing plate is still supported by the central support, so the rigidity will not be destroyed at any time.
The difference between precision stamping and ordinary stamping lies in the requirements for stamping equipment and the accuracy of stamping parts required. If the precision of stamping parts is required to be high and the quantity of stamping parts is large, you can choose to use precision stamping. On the contrary, if the precision of stamping parts is not required to be high, and the stamping is made of ordinary sheet material, you can choose ordinary stamping. This needs to be based on your own The stamping features are selected.
