Stamping production belongs to material forming technology. In recent years, it is a new method of metal cold deformation processing. It is one of the main methods of metal plastic processing. In the production of stamping parts, people use the power of conventional or special stamping equipment to stamp, use pressure to make the material deform, and then use the sheet metal deformation in the die to get product parts with a certain size and shape. What problems should we pay attention to in the production?

In the production of stamping parts, when we use the press or die and other engineering equipment, we should pay attention to the use of normal working conditions, so as to effectively prevent strips from being able to transfer materials along the correct positioning, or according to a certain gap we predetermined ahead of time. Material. We guarantee the fastening of parts everywhere in the die. Note that during the production of stamping parts, do not change the installation position of the die. Once the change occurs, it will scratch or crush the surface of the workpiece, which has a great impact on the quality of the workpiece. Another point is that when we prepare materials, we must abide by technical specifications, pay attention to accurate measurement of raw material size, and strictly check raw materials and brand. In addition, when we are producing stamping parts, we must inspect abrasives and some punches regularly to prevent wear and tear of working parts and guiding parts due to long-term operation. Strictly abide by the stamping parts in the production of the relevant precautions, in order to avoid unnecessary losses.

A large number of cold stamping processes have been adopted in the production of automobile stamping parts, which are suitable for the needs of multi-variety and mass production of automobile stamping parts industry. In medium and heavy trucks, most of the panels, such as body panels, and some load-bearing and supporting parts, such as frame, carriage and other automotive parts, are automotive stamping parts. Automobile stamping parts indicate that steel used for cold stamping is mainly steel sheet and strip, accounting for 72.6% of the total steel consumption. Cold stamping materials are closely related to the production of automobile stamping parts. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping parts, and affects the quality of products. Cost, service life and production organization, so the rational selection of materials is an important and complex work.

The design of stamping parts must follow the simple shape, reasonable structure and simple process. The assembly is convenient and easy to maintain. Besides, the use and technical functions of the products should be achieved. Consider as many points as possible in the design process to increase product life. Save raw materials as much as possible and achieve zero loss within the allowable range.
