Quality requirements and principles of stamping parts

Since stamping parts have become larger and more complex, the quality requirements of stamping parts have become more and more stringent. In order to complete these guidelines, stamping parts manufacturers have put forward related quality control guidelines, which are reflected in fineness, fineness and exquisiteness. Degree and so on. In order to satisfy the fineness criterion of stamping parts, the number of processes for drawing parts needs to be confirmed through drawing process accounting, because it is not only related to the nature of the material, drawing height, number of drawing steps and other factors, but also related to the drawing diameter , Data thickness and other conditions. The second is about the fine criteria of stamping parts. The number of processes as a zigzag part mainly depends on the degree of messiness of its structure and shape, so it needs to be based on the number of zigzag angles, relative orientation, and zigzag direction. It has already reached the requirements of fineness and fineness. Naturally, the rule of fineness cannot be ignored. When the section quality and dimensional accuracy of the stamping parts are required to be high, it is possible to consider adding a trimming process after the punching process, or directly select fine punching. Cutting process, and then get exquisite stamping parts. When manufacturing simple-shaped stamping parts, it is possible to select a single-process mold. However, when punching a messy-shaped workpiece, because the structure or strength of the mold is limited, the internal and external generalization should be divided into several parts, so more For metal stamping processing procedures, if necessary, successive molds can be used. In order to ensure the quality of fine metal stamping parts and improve the stability of the process, it is common to add the number of processes, such as the additional positioning process hole punching of zigzag parts, and the additional deformation in the forming process to reduce the hole punching to transport the deformed area, etc. , Can indeed contribute to the improvement of the quality of stamping parts.
