What are the production and fabrication methods of metal automobile stamping parts?

Automobile stamping parts are the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force in the mold and deformed. Sheet material, mold and equipment are the three elements of stamping fabrication. Stamping is a metal cold deformation fabrication method. Therefore, it is called cold stamping or sheet stamping, or stamping for short. It is one of the main methods of metal plastic working (or press working), and also belongs to material forming engineering technology.

Of the steel in the world, 50-60% are made of sheets, most of which are finished products that have been pressed. Car body, radiator fins, steam drums of boilers, shells of containers, iron core silicon steel sheets of motors and electrical appliances, etc. are all stamped and processed. There are also a large number of stamping parts in instruments, household appliances, office machines, storage utensils and other products. Stamping is an efficient production method, using composite molds, especially multi-station progressive molds, which can complete multiple stamping technical operations on one press to complete the automatic generation of materials. The production speed is fast, the rest time is long, the production cost is low, and the collective can produce hundreds of pieces per minute, which is favored by many fabrication plants.

Stamping parts are more powerful than castings and forgings, and have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, ribs, coils or flanges that are difficult to manufacture in this skilled diameter to improve their rigidity. Due to the rejection of rough molds, the precision of the workpiece can reach micron level, and the precision is high and the specifications are consistent, and holes, bosses, etc. can be punched out. In actual production, technical tests similar to the stamping process are often used, such as deep drawing performance tests, bulging performance tests, etc. to test the stamping performance of materials to ensure the quality of finished products and high pass rate.

Stamping equipment usually adopts stagnation press except for thick plate forming with water press. Focusing on modern high-speed multi-station stagnation presses, the equipment is equipped with stagnation such as unwinding, finished product collection, conveying, as well as die storage and quick die change placement, and the use of computerized tube bundles can form passive stamping production with high production rate and high production rate. Wire. Under the condition that dozens or hundreds of stamping parts are produced every minute, the stamping, parts and other processes are completed in a short time, and personal, equipment and quality problems often occur. Therefore, safe production in stamping is a very important issue.
