Compared with castings and forgings, the stamping parts are thin, uniform, light and strong, and the stamping parts are thin, uniform, light and strong. Stamping can produce reinforcing bars, reinforcing bars and other stamping parts, stamping bars, ups and downs, flanging and other workpiece, improve the rigidity of the workpiece. Due to the use of precision die, the precision of the workpiece can reach micron level, high repetition precision, consistent specifications, can punch, punching boss. In general, cold-pressed parts are no longer machined or require only a small amount of cutting. The precision and surface state of hot stamping parts are lower than that of cold stamping parts, but still better than that of castings and forgings, and the cutting amount is small. Stamping is an effective production method. The use of composite die, especially multi-station progressive die, can be in one press (single station or multi-station) to complete the multi-channel stamping process, to realize the strip from uncoiling, leveling, forming, finishing automatic production. High production efficiency, good working conditions, low production cost, generally can produce hundreds of pieces per minute. Compared with other machining and plastic machining methods, stamping tee has many unique advantages in technology and economy. The main performances are as follows. (1) the stamping process has high production efficiency, convenient operation, and is easy to realize mechanization and automation. This is because stamping to rely on stamping die and stamping equipment to complete the processing, ordinary stamping stroke can reach dozens of times per minute, high speed pressure can reach hundreds of times or even thousands of times per minute, and each stamping stroke can get a stamping part. (2) in order to ensure the surface quality of stamping parts, die life is generally long. Stamping quality stability, good interchangeability, with the same characteristics. (3) stamping can produce large size range, complex shape parts, such as clocks and stopwatches, car rails, covering parts, etc., in addition, the cold deformation and hardening effect of materials in the process of stamping makes the strength and stiffness of stamping parts improve. (4) general stamping parts without chip, no scrap, less material consumption, do not need other heating equipment. Therefore, stamping is a kind of material saving and energy saving processing method, stamping parts cost is low.
