What problems need to be paid attention to in the production of automobile stamping parts

The stamping parts production belongs to the material forming technology. In recent years, it is a new metal cold deformation processing method. It is one of the main methods of metal plastic processing. When the stamping people power by conventional or special punching equipment punching, the deformation of the material by the pressure, and then use the sheet metal mold deformation, to get the size and shape of the product has certain parts, in the production time, need to pay attention to what the problem?

In the stamping production time, when in use, press or die engineering equipment to our attention, we are going to use under normal working conditions, which can effectively prevent the strip along the correct location cannot transfer material, or not according to the US ahead of the scheduled clearance good feeding. We are to ensure a fastening, die parts throughout the attention in the stamping die, not every installation position change, once changed, will crush or scratch the surface of the workpiece, so as to influence the quality of the workpiece is very large. Another point is that when we are preparing materials, we must comply with the technical specifications, pay attention to the accurate measurement of raw material dimensions, and strictly check the raw materials and brand. What's more, when we are doing the stamping production, we must regularly inspect the grinding tools and some punching machines to prevent wear and tear of the working parts and guiding parts because of long-term operation. Strictly observe the relevant matters of attention in the production of stamping parts so as not to cause unnecessary loss.

A large number of cold stamping processes are used in the production of stamping parts for automobile stamping parts, which are suitable for many varieties and large batch production of automobile stamping parts industry. In heavy duty vehicles, most of the panels, such as body panels, and some load bearing and supporting parts, such as frames and cars, are all automotive parts. Auto stamping parts for said cold stamping is mainly steel sheet and strip steel accounted for 72.6% of the total consumption of the vehicle, the relationship of cold stamping materials and automotive stamping parts production close performance materials not only determine the product, but also directly affect the design process of automobile stamping process, affect the product quality and cost service life and production organization, so the reasonable selection of materials is an important and complicated work.

The design of stamping parts must be simple in shape and reasonable in structure. The assembly is convenient and easy to repair. In addition, the use and technical function of the product should be achieved. In the process of design, consider as many points as possible to increase the life of the product. Save the raw materials as much as possible, so as to achieve zero loss as far as possible within the permitted range.
