The entire manufacturing process of automobile stamping parts involves many key points, and attention should be paid to several aspects, such as the selection of basic stamping processes, and the scientific selection of stamping processes can ensure the improvement of the overall efficiency of the manufacturing process.
Edge trimming, flanging and blanking in common stamping processes are relatively important processes, and they also have distinct characteristics. The nature of some processes can be intuitively seen from the parts diagram. Punching and shearing are commonly used. process.
Open cylindrical parts can be made by deep drawing. The parts must be combined with supply and demand to determine the nature of the process by calculation and analysis. During the process selection process, the shapes of the stamping parts of the oil seal outer clamp ring and the inner clamp ring are similar, only in the outer diameter and the straight edge. There are differences in height, and it is necessary to carry out detailed calculation and analysis before selecting a process.
Furthermore, it is necessary to pay attention to the number and sequence of stamping to ensure the quality of operation in this link. The number of repetitive processes is the number of stampings. For deep-drawn parts, it is necessary to combine the deformation of sheet metal subjects and the calculation of size factors. The number of times of deep drawing, and bending parts and flanging parts should pay attention to the calculation of the number of stamping times in combination with the limit deformation degree and specific shape, so as to avoid reducing the number of processes, pay attention to fully exert the effect of material plasticity, and combine the process quality requirements. As well as the deformation characteristics, the stamping sequence is arranged, and these aspects can be strengthened to help effectively control the operation quality of each item.
In addition, in the process of stamping parts manufacturing process combination, it is necessary to choose the appropriate method. The completion of stamping parts requires multiple processes, and the preparation of process plans is more important. Do a good job in the consideration of processes, and pay attention to multi-process combination and single process. Combination of processes, continuous mould production as well as compound mould production.
The precision requirements of stamping parts and the size of the parts are important reference factors for selecting molds. For mass production, it is necessary to combine stamping processes. Continuous die stamping and compound die selection are more appropriate. If the batch is relatively small For production, it is necessary to choose a single-process simple die. When the size of the stamping parts is relatively small, the problem of inconvenient feeding productivity of the single-process die should be fully considered. The composite die or the continuous die should be used as the main method, and the automatic feeding should be continuous. Only by focusing on the mold and doing a scientific combination of processes can it help to improve the application efficiency of the process.
