What Is the Difference Between Precision Stamping and General Stamping?

In industrial production, various materials and shapes of parts are needed, and the production of these parts requires stamping. Stamping is a production technology for producing parts with certain shapes, sizes, and properties by using the power of conventional or special stamping equipment to directly deform the sheet metal in the mold, thereby stamping it under a certain deformation force. Stamping can be divided into precision stamping and ordinary stamping.

Introduction to precision stamping and ordinary stamping

Precision stamping is a material processing method developed on the basis of ordinary stamping technology. It is to achieve precision stamping or composite processing of precision stamping and other forming processes under the strong three-directional compression stress conditions by improving the guiding accuracy, reducing the clearance between convex and concave molds, increasing the reverse pressure and V-shaped ring pressing, and other process measures, so as to obtain precision stamping parts.

Precision stamping requires high precision for stamping parts. In the process of processing production, appropriate technical support such as precision stamping machines, molds, materials, and lubricants must be considered, and the requirements are high.

Ordinary stamping requires less precision for stamping parts, but it also has specific market demand. The substrate is thick and does not require cutting, cutting, stretching, etc. The stamping material is sheet metal, pipe, etc. When the product order quantity is not large, ordinary stamping can meet the requirements.

In the process of processing and production of precision stamping parts, appropriate technical support such as precision stamping machines, molds, materials, and lubricants must be considered.

On the end face of the product's scrap ejector, apply about 25% of the main punching and trimming pressure, called reverse pressure. These three pressures do not interfere with each other, and the size of each pressure is synchronized with the forming, punching, and other processing requirements, and can be adjusted arbitrarily. In addition, the processing speed must also be adjusted according to the processing object requirements of forming or punching. The construction of the mold not only requires simplicity and light weight but also must be suitable for the requirements of use.

When processing thick plates, for molds that are prone to deformation, there is no obvious deformation due to the use of central support. Even when the workpiece is squeezed into the concave mold during blanking and punching, if the scrap ejector moves back, the inside of the concave mold is also supported by the central support. If the oil pressure piston is connected to the gear plate on the side of the punching mold, the gear plate on the side of the punching mold is still supported by the central support when the piston moves back, so the rigidity will not be destroyed at any time.

Differences between precision stamping and ordinary stamping

It depends on the requirements of the stamping equipment and the precision of the required stamping parts. If high precision and large volume of stamping parts are required, precision stamping can be selected. On the contrary, if the precision of stamping parts is not high, and ordinary plate material is used for stamping, ordinary stamping can be selected, which needs to be selected according to its own stamping characteristics.
