Metal stretching parts are widely used in various fields of our life, including some electronic devices, auto parts, decorative materials and so on. The stretched parts we usually refer to generally refer to hot-stretched parts. For example, if you want to turn an iron plate into a stainless steel basin, you must first design a set of molds. The working surface of the mold is the plate. Shape, press the iron plate with a mold, and it becomes the pot you want. This is hot stretching, which is to directly stretch the hardware material with the mold, so that a metal stretching part will be formed. The processing of stamping parts includes blanking, bending, deep drawing, forming, finishing and other processes. The materials for stamping parts are mainly hot-rolled or cold-rolled metal sheets and strips, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloy sheets, aluminum and aluminum alloy sheets Wait. The PHP series of portable surface Rockwell hardness testers are ideal for testing the hardness of these stampings. Alloy stamping parts are the most commonly used parts in the fields of metal processing and machinery manufacturing. The processing of stamping parts belonging to hardware is a processing method that uses a mold to separate or form a metal sheet. Its application range is very broad. The design of the metal stamping parts factory should not only ensure good performance, but also have good process performance to reduce material consumption, extend die life, improve productivity, reduce costs and ensure the quality of stamping parts. Compared with castings and forgings, metal stamping parts have the characteristics of thinness, uniformity, lightness and strength. The processing of metal stamping parts can produce workpieces with ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to improve their rigidity.
