Rolling parts manufacturers-Automotive rolling parts

  Rolling parts manufacturers - what are the automotive stamping parts:


  The utility model of rolling parts manufacturer relates to a spring plate, spring bracket, spring bracket, end cover, cover, compression valve cover, compression valve cover, oil seal seat, bottom cover, dust cover, impeller, Oil cylinders, lifting lugs and brackets belong to automobile stamping parts. Auto stamping parts, as the name suggests, are metal stamping parts in auto parts.

  In automobile stamping parts, one part is directly stamped into auto parts, while the other part can only be made into auto parts through welding, machining or painting. When selecting materials for rolling parts manufacturers, we must first select metal materials with different mechanical system properties according to the type and characteristics of automotive stamping parts, so as to ensure the quality of enterprise product services and save materials. The selection of auto stamp materials should generally follow the following principles:


  1. The selected materials should first meet the performance requirements of auto parts;


  2. The selected materials should have good process performance;


  3. The selected building materials should have a good economy. In the production of automobile stamping parts, a large number of cold stamping processing processes are adopted by an enterprise, which is suitable for the design and production of multi-variety and large-volume products in the traditional Chinese automobile stamping parts industry. In medium and heavy vehicles, covering parts such as body panels, as well as some main load-bearing structural supports such as frames and compartments, most of them are stamped parts of Chinese automobiles.


  Stamping is the pressing and molding of sheets, strips, pipes and profiles, such as the application of external force, the forming process can develop products of the desired shape and size that affect the deformation or separation of the plastic material for the processing of the workpiece. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can be used to increase the rigidity of workpieces with specific stiffeners, ribs, undulations or flanges that are more difficult to fabricate by other research methods.


  Roller pressure is primarily determined by the rolling of plastic moving material into products such as complex shafts, spools and special fasteners of various shapes. The pressure deformation of the roller is a kind of linear contact, which is continuously developed step by step. The required deformation force is very small, and one effective stroke can affect one or more workpieces. Compared with the cutting and grinding process, the roll forming process not only has high production efficiency and saves materials, but also has high strength and stable quality.


  When the rolling part manufacturer adopts the stamping process to produce the threshold reinforced plate, the product quality characteristics only need to meet the conventional process design requirements such as the depth of the forming technology, the r-angle size, and the negative angle, while when the threshold reinforced plate is produced by the rolling process, the product characteristics are There are special requirements, for example, the lower forming surface, forming boss, flange size, cutting edge line, etc. must meet the requirements of the rolling production process.


  Due to the poor elongation of high-strength plates, especially ultra-high-strength steels whose tensile strength is greater than 780MPa, it is inevitable for roll-pressed parts manufacturers to use roll-pressed composite material forming technology to produce special-shaped cold-formed steel, such as bumpers Bodywork, bumpers, door sills, seat rails, etc. Cold-formed parts with holes need to use online blanking, welding, automatic cutting and other equipment to form a fully automatic production line, which also requires breakthroughs in some key technologies.
