How to ensure the quality of automotive precision stamping parts? 'Hardware'

Automobile precision stamping parts will encounter such and other problems in the production process. It is inevitable that there will be abnormal marks. After polishing the surface with oilstone, bright spots and bright marks will appear. Scratches and bumps are generally caused by workers' careless operation. The turnover of parts is also prone to occur, and the more turnover, the more chances of bumps and scratches will occur. So how can we guarantee the quality of automotive precision stamping parts? Let me explain the hardware below. Methods to ensure the quality of automotive precision stamping parts: 1. When the automotive precision stamping parts are stretched, they will be compressed and deformed and produce wrinkles. In order to avoid such phenomena, we can increase the internal force to remove the tensile stress. Wrinkles can also be reduced by increasing stretch ribs and reducing the radius. If he is partially deformed, then our stretching force will be higher. If the deformation of the outer material is too large, then there will be cracks. If we want to avoid this problem, then we must cut the material to ensure the quality of the material. 2. If the tensile deformation force of the locally deformed stamping part is higher than that of the side wall material, it will cause two-way elongation and deformation. If the external material cannot supplement the internal part, it is considered that the deformation is too large and breaks. I want to overcome this situation , The blanking method should be used first to cut the material to ensure the quality of the edge section of the material, thereby improving the edge state of the material, and appropriately increasing the material size to effectively determine the size of the concave flanging material. 3. The surface polished by oil will have a lot of bright spots and bright marks. If there are scratches or bumps, it is caused by our operators' carelessness. Of course, it is easy to turn over the parts. If there are scratches, the chances of collisions will increase if there are more turnovers. The above are the three methods of how to ensure automotive precision stamping parts. In order to ensure the quality of automotive precision stamping parts, we remind friends to pay more attention to stamping work to avoid unnecessary losses.
