Under the background of the current social and economic development, people's quality of life has been further improved, and people's car ownership has also been greatly improved, which has also led to the prosperity of the automobile manufacturing industry. Automobile metal stamping parts manufacturing is an important part of automobile production. This paper first expounds the role of stamping parts manufacturing technology development, and then discusses the manufacturing process and mold design in depth, from the theoretical level, the manufacturing process of automobile metal stamping parts is discussed. Then, let's learn about the manufacturing process of automobile metal stamping parts!

1. The role of stamping technology development

At present, the automobile manufacturing industry chain development mode is implemented. In the development of automobile stamping technology, it is necessary to combine the actual market application requirements. Through the research on the development of automobile stamping technology, the technical quality level is improved, the product quality performance of stamping parts is guaranteed, the construction period is greatly shortened, and the cost is reduced. In addition, the development of stamping technology is the need of today's market development to meet people's needs for improving automobile quality, improve people's experience of using products and bring business opportunities for the good development of the automobile industry. Rationalized automobile stamping technology helps to improve the performance of automobiles, reduce the cost of mold use, and plays a positive role in promoting the sustainable development of automobiles.

2, Automotive hardware stamping parts manufacturing process and mold design

Production Process of Automotive Hardware Stamping Parts

The whole process of automobile metal stamping parts manufacturing process involves many aspects, and we must pay more attention to it from several aspects. For example, we must pay more attention to the selection of the basic stamping process, and the scientific selection of the stamping process can ensure the improvement of the overall efficiency of the process. The common trimming, flanging and punching in the stamping process are important processes and have distinct characteristics. According to the nature of the process, it can be seen intuitively from the part drawing that punching and cutting are commonly used processes. Open cylinders that can be made by deep drawing, parts must be calculated and analyzed according to supply and demand requirements to determine the nature of the process. In the process of process selection, the shape of the outer ring and inner ring pressure plate of the oil seal is similar, but the outer diameter and the height of the straight edge are different, and the selection can only be made after detailed calculation and analysis.

mold design

In the process of mold design, we must strengthen control from several aspects. Such as mold structure form and mold mold determination, production batch and precision requirements control, closely combined with the shape characteristics of parts, to ensure good process execution and operation safety. From the single mode selection and continuous mode selection, combined with the actual needs, improve the life and strength of the mold, the structure form and type should be consistent with the actual application requirements. The strength of the mold in use must be paid full attention to. The composite type is easy to focus on quality problems such as flanging and punching. This problem must be properly solved and attention must be paid to improving the quality of the composite type. Pay attention to the selection surface of the workpiece positioning method to make it conform to the design standard. If it is not effective, it is necessary to pay more attention to the calculation of the dimension chain, do a good job in tolerance distribution, convert the design dimension into the process dimension, and improve the machining accuracy of the parts as a whole. For the production of parts to choose different mold multi-process stamping, it is necessary to ensure the unity of process standards. In order to ensure the reliability of positioning, it is necessary to select a high-precision and non-offset positioning surface. Even the same positioning surface changes depending on the shape of the part, so please pay attention to the control of accuracy. We should pay attention to the design and production standards of mold parts, pay attention to the calculation of mold working parts, design and positioning and many other aspects of scientific control, to ensure that the quality of mold design meets the practical standards, only these aspects can be guaranteed, in order to improve the quality of the mold.

In short, in the implementation of the manufacturing process of automotive metal stamping parts, only the relevant personnel themselves multi-angle thinking, multi-faceted optimization, clear the method and quality of the manufacturing process, in order to have a good control of the actual process. Fully study and analyze the manufacturing process of stamping parts, we can understand the importance of process optimization from the theoretical level.
