What is stamping, stamping

Through mould plate produce plastic deformation and a method of forming process is called to obtain the finished parts stamping. Because stamping usually under the cold, also known as the cold stamping. Only when the plate thickness more than 8 ~ 100 mm, with hot stamping. Stamping processing of raw materials is commonly sheet or strip, also calls the sheet metal stamping. Some non-metallic sheet ( Such as veneer, mica, asbestos, leather, etc. ) Can be processed by stamping technology. Stamping is widely used in metal products industry, especially in the automotive, instrumentation, military industry, household electrical appliances industry occupies an extremely important position. Stamping need research process equipment and mold three basic questions. Sheet metal stamping has the following characteristics: ( 1) High material utilization. ( 2) Machining of thin wall and complex shape parts. ( 3) Stamping parts interchangeability in shape and size. ( 4) To gain weight and high strength, rigid good parts. ( 5) Productivity is high, the operation is simple, easy to realize mechanization and automation. Stamping die production cost is high, so is suitable for mass production. For small batch and many varieties, production often USES simple punching die, introduced at the same time stamping machining centers and other new equipment, to meet the needs of the market to change. Commonly used metal sheet stamping material with low carbon steel, copper, aluminum, magnesium alloy and high plasticity of alloy steel, etc. As mentioned above, the material shape of plate and strip. Stamping production equipment have shears and punch. Shearing machine is used for plate shear into a certain width of the strip material, used for later punching process, punching machine can be used for cutting and forming.
