This is the new technology of the original stamping factory?
With the development of the times and the advancement of science and technology, many new technologies have been born in stamping processing plants in order to survive and compete. Let's follow the author to understand. The composite stamping mentioned here does not refer to the composite of blanking, drawing, punching and other stamping processes, but refers to the composite of the stamping process and other processing technologies, such as the composite of stamping and electromagnetic forming, stamping and cold Combination of forging, combination of stamping and machining, etc. Composite process of stamping and electromagnetic forming Electromagnetic forming is high-speed forming, and high-speed forming can not only expand the aluminum alloy forming range, but also improve its forming performance. The specific method of forming aluminum alloy cover parts by composite stamping is: use a set of convex and concave molds to install electromagnetic coils at the sharp corners and difficult-to-form contours of the aluminum alloy cover parts, form them by electromagnetic methods, and then use a pair of molds The easy-to-form part of the cover is formed on the press, and then the preform is deformed at a high speed with an electromagnetic coil to complete the final forming. Facts have proved that using this composite forming method can obtain aluminum alloy panels that are difficult to obtain with a single stamping method. The latest research shows that magnesium alloy is a metal with high specific strength, good rigidity, and strong electromagnetic interface protection performance. Its application prospects in electronics, automobiles and other industries are very promising, and it can greatly replace traditional ferroalloys, aluminum alloys, and even plastic materials. trend. Magnesium alloy parts currently used in automobiles include instrument panels, seat frames, engine covers, etc. Magnesium alloy pipe parts are also widely used in cutting-edge industrial fields such as airplanes, missiles, and spacecraft. However, the close-packed hexagonal lattice structure of magnesium alloy determines that it cannot be stamped and formed at room temperature. Now people have developed a mold that integrates heating and forming to stamp and form magnesium alloy products. The product forming process is as follows: during the descending process of the punch slide, the upper die and the lower die are clamped to heat the material, and then the material is formed in an appropriate motion mode. This method is also suitable for the connection of molded products and the composite molding of various products in a punch press. Many difficult-to-form materials, such as magnesium alloys, titanium alloys and other products, can be stamped and formed by this method. Because this kind of punching requires the punch slider to have a pause function during the descending process, so as to provide time for heating the material, a new concept of punching machine-CNC crankshaft servo motor punching machine was developed. The punching machine can also be used for punching. Compound processing including tapping, riveting and other processes is realized in the mold, which effectively expands the range of stamping processing and lays a solid foundation for the wide application of magnesium alloys in the plastic processing industry. Combination of stamping and cold forging Generally sheet metal stamping can only form parts with the same wall thickness, and thin-walled parts with thick bottom can be obtained by thinning and stretching. The limitations of stamping forming limit its application range. In the production of auto parts, it is often encountered that some thin-walled but unequal-thick parts are formed by a composite plastic forming method that combines a single stamping and cold forging. Therefore, it is easy to use a combination of stamping and cold forging. The method can expand the range of sheet metal processing. The method is to pre-form by stamping method, and then finally form by cold forging method. The advantages of stamping and cold forging compound plastic forming are: First, the raw materials are easy to purchase at a low price, which can reduce production costs; the second is to reduce the large forming force required for a single cold forging, which is conducive to improving the life of the die. 15 years of experience in metal stamping processing, more than 20 sets of imported stamping equipment.
