Car stamping parts will encounter such and other problems during the production process. It is inevitable that there will be abnormal marks. The surface of the oilstone will be polished, and bright spots and bright marks will appear. Scratches and bumps are generally caused by the careless operation of the workers. Parts turnover will also happen easily, and the more turnover, the more opportunities for bumps and scratches.
How can we guarantee the quality of car stamping parts? The following hardware experts will explain to you.
Ways to ensure the quality of car stamping parts
- 1. When the car stamping parts are stretched, they will shrink and deform and then produce wrinkles. In order to avoid this kind of phenomenon, we can advance the internal force to the tensile stress to eliminate wrinkles, and we can also add stretching ribs. And the reduction of the radius. If part of it is deformed, then our stretching force will be higher. If the deformation of the outside material is too large, there will be splits. If we want to avoid this problem, then we must first cut the material to ensure the quality of the material. To
- 2. Assuming that the tensile deformation force of the partially deformed stamping part is higher than that of the side wall material, it will lead to two-way elongation deformation. Assuming that the external material cannot compensate for the internal part, it is assumed that the deformation is too large, splitting, and want to defeat this situation Therefore, blanking should be used first to cut the material to ensure the quality of the edge section of the material, and then to improve the edge condition of the material, and the material standard should be appropriately increased to effectively determine the standard of the concave flanging material.
- 3. The surface polished by oil will have many bright spots and bright marks. If there are scratches or bumps, they are all caused by our operators’ carelessness. Of course, it is also very simple when the parts are turned over. If there are scratches, if there are more turnovers, there will be more chances for bumps.
