What are the differences between precision stamping and ordinary stamping?

In industrial production, we will need parts of different materials and shapes, and these parts need to be stamped. Stamping processing is the production technology of the product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the sheet material is directly subjected to deformation force in the mold, and the 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 process. It is made by improving the guiding precision, reducing the gap between the convex and concave molds, increasing the reverse pressure and the V-ring ring and other technical measures. Under the condition of three-way compressive stress state, precision stamping or precision stamping is combined with other forming processes to obtain precision stamping parts. Precision stamping requires high precision for stamping parts. In the process of processing and production, stamping coils or forming, it is necessary to consider the appropriate technical matching of precision punching machines, molds, materials, lubricants, etc., and the requirements are relatively high. Ordinary stamping does not require high precision for stamping parts, but it also has its specific market demand. The thickness of the substrate is thick and does not require cutting, cutting, stretching and other processes. The stamping materials are sheets, tubes, etc. When it is not big, it can meet the requirements with ordinary stamping. In the process of precision stamping parts processing, stamping coils or forming, must consider the appropriate technical support for precision punching machines, molds, materials, lubricants, etc. Precision stamping needs to be produced by precision punching machines. The construction, pressure effects and safety devices of the press have the following requirements: 1. High rigidity in vertical and horizontal directions 2, mold installation workbench, when the mold pad is installed, the deformation is minimal 3, easy to achieve the best working condition 4. There must be measures to prevent damage to the mold. For precision punching machines, in addition to the punching pressure of the machining center, as an advantageous method to improve the deformation ability of the processing materials, there are two auxiliary devices for generating hydrostatic pressure. Pressure generating device. One is a Y-shaped annular protrusion designed on the pressure plate along the contour of the part, because the punching pressure is about 50{1d8a2c365ffc689a7880b1695f000798168d4e5e5e0143bcff88df95ff2ffb4a} for pressing on the material to be processed, which is called a ring gear pressure plate. The other end of the product’s stripper is applied with a main punching pressure of about 25{1d8a2c365ffc689a7880b1695f000798168d4e5e5e0143bcff88df95ff2ffb4a}, which is called back pressure. These three pressures do not interfere with each other, and each pressure is synchronized with the shape, and must be suitable for processing requirements such as forming and punching, and can be arbitrarily adjusted. Titanium Machinery is the main product of the company with rotary top, screw, shaft machining, CNC lathe machining, shank shank and collet post. In addition, the machining speed must also be based on the forming or blanking requirements of the processing object. Adjustment. The construction of the mold is not only simple and lightweight, but also suitable for use. In the case of processing a thick plate, for a mold which is easily deformed, since a center support is employed, there is no significant deformation. Even in the blanking process, when the workpiece is squeezed into the die, if the unloader is retracted, the inside of the die is supported by the center support. If the hydraulic piston is connected to the side of the ring gear platen, the piston is retracted, and the inside of the die ring plate is still supported by the center, so the rigidity will not be broken at any time. The difference between precision stamping and ordinary stamping lies in the requirements of the stamping equipment and the precision of the required stampings. If the precision of the stamping parts is required, and the stamping parts are large, you can choose to use precision stamping. Otherwise, if the precision of the stamping parts is not high, and it is stamped by ordinary sheets, you can choose ordinary stamping, which needs to be based on its own Stamping features are selected.
