1. Automotive stamping
Define automotive stampings
automotive stamping, by definition, composed of a metal stamping auto parts. In automotive stamping member, a portion of the automotive stampings and pressed directly into the auto parts, the other part after welding and the like after punching needed, or machined, or paint can be crafting automotive components. A wide variety of automotive stampings, stamping parts such as automotive shock absorbers of the spring tray, a spring seat, the spring bracket, cap, lid, bonnet compression, compression valve sleeve, oil seal seat, the bottom cover, dust cover, impeller, oil cylindrical, lug, the bracket belong automotive stampings.
Selection principle automotive stampings
When selecting the material, according to the first type and use of automotive stamping characteristics, to select metal materials having different mechanical properties, thus achieving ensure product quality, but the purpose of saving material.
is usually followed in the choice of materials automotive stampings following principles:
a first material selected should meet the performance requirements of automotive components;
B chosen material have better process performance;
c material is selected to have a better economy. Raw automotive stamping reasonable selection
automotive stampings used in the production of a large number of cold-stamping process for automotive stampings many varieties of industrial mass production needs. In heavy-duty vehicles, most of the vehicle body outer cover plate, and a number of load-bearing members such as the frame and the support, carriage and other automotive components are automotive stamping. Steel for cold stamping mainly steel sheet and strip, steel consumption accounted for 72.6 percentage of the vehicle, the relationship between cold stamping materials and automotive stamping parts production very closely, not only determines the quality of the material properties of the product, but also directly affect the automotive stamping technology process design, affecting product quality, cost, service life and production organization, and therefore a reasonable choice of material is importantAnd complex task.
