Reasonable selection of equipment and application of new technologies for metal

1、 The reasonable selection of equipment for stamping parts is analyzed based on various aspects such as stamping force, mold structure, and height in the actual manufacturing process. Combining the existing manufacturing infrastructure, the application of facilities is closely related to the design of molds. It is necessary to develop relevant design requirements and determine the type of equipment based on the relevant design. If the equipment used for manufacturing is small and the calculation values related to stamping are small, but the specifications required for the mold are large, the facilities that need to be selected are relatively large. Select equipment that meets the height and leakage hole size based on the actual specifications of the mold. The design of the mold needs to pay attention to these aspects: first, the balance between the punching force and the mold; Next, calculate the data and calibrate the relevant power; In the bending and other processes, in order to address quality issues with the parts, it is necessary to calibrate the manufacturing process to ensure smooth production of automotive parts. The body, internal structure, and seats of a car are all made of steel plates through stamping technology. Automotive metal stamping parts; The manufacturing process is the basic technical capability of automobile production, which ultimately determines various aspects such as the cost-effectiveness and appearance of the automobile body. The intuitive part of a car's composition is its body, which is also an important component of the car. The manufacturing process of automobiles is directly related to their service life, and the improvement of stamping manufacturing technology for automotive parts is an important competitive advantage in the automotive industry. 2、 The application of stamping parts in the automotive industry is a major consumer of steel. With the continuous rise in raw material prices and the continuous decrease in automotive prices, the profit margin of the industry is greatly affected. Saving resources, improving costs, and reducing costs are the necessary paths for enterprises. In the production of raw materials, steel accounts for 60% to 70% of the total consumption, and only a part of the steel consumed in the production process is directly transferred to stamping parts, forming metal stamping parts; The entity, the rest becomes waste. Therefore, improving the utilization rate of steel through various process improvements is a way for enterprises to reduce costs. 1. The application of laser welding can not only significantly reduce the number of fixtures, improve production efficiency and assembly quality, but also greatly improve material utilization by adopting laser welding. At present, the company's TWB technology has been widely applied to vehicle models, and domestic mold technology is becoming increasingly mature. It is recommended to adopt laser welding as the data structure for future projects to reduce the number of mold sets and improve material utilization. 2. The application of waste free uncoiling stamping parts varies in shape, and material utilization can be improved by adjusting the shape of the raw material. At present, the unwinding equipment has a swing shear function, which can achieve a trapezoidal structure through the equipment. The utilization of waste free unwinding methods can greatly improve material utilization. The overall length of the mold can be saved by 450mm, the total weight of the mold is about 6t, and the cost can be saved by about 250000 yuan. The material utilization rate before the change was 30.2%, and after the change, the material utilization rate was 40.20%. Calculated with a dimension of 200000, the saved sheet metal cost is about 1.156 million.
