Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to increase their rigidity.

    Due to the use of precision molds, the precision of the workpiece can reach the micron level, and the repeatability is high, and the specifications are consistent, and holes, bosses, etc. can be punched out. Cold stampings are generally no longer cut, or only require a small amount of cutting. The precision and surface condition of hot stamping parts are lower than those of cold stamping parts, but still better than castings and forgings, and the cutting amount is less.

    Stamping is an efficient production method. Using composite dies, especially multi-station progressive dies, can complete multiple stamping processes on one press (single-station or multi-station), realizing uncoiling and straightening of strip materials. Fully automatic production from flat, blanking to forming and finishing.

   The production efficiency is high, the working conditions are good, and the production cost is low. Generally, hundreds of pieces can be produced per minute. Compared with other methods of mechanical processing and plastic processing, stamping processing has many unique advantages in terms of technology and economy. The main performance is as follows.

(1) The production efficiency of stamping processing is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because stamping relies on dies and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach dozens of times per minute, and high-speed pressure can reach hundreds or even thousands of times per minute. Possibly get a stamped piece.

(2) During stamping, because the mold ensures the size and shape accuracy of the stamping parts, and generally does not damage the surface quality of the stamping parts, and the life of the mold is generally longer, so the quality of the stamping is stable, the interchangeability is good, and it has "exactly the same" Characteristics.

(3) Stamping can process parts with a large size range and complex shapes, such as stopwatches as small as clocks and watches, as large as car longitudinal beams, covering parts, etc., plus the cold deformation and hardening effect of materials during stamping, the strength of stamping and The stiffness is high.

(4) Stamping generally does not generate chips and scraps, consumes less material, and does not require other heating equipment, so it is a material-saving and energy-saving processing method, and the cost of stamping parts is low.
