What principles should be followed in the processing of precision stamping parts? 【Hardware】

Hardware tells you what principles should be followed for precision metal stamping parts: 1. For workpieces with complex shapes, due to the restriction of the structure or strength of the mold, the inner and outer contours should be punched in several parts, requiring multiple stamping processes. For workpieces with high flatness requirements, a leveling process can be added after the punching process. 2. The number of procedures for the bending part mainly depends on the complexity of its structure and shape, and is determined by the number of bending angles, relative positions and bending directions. When the bending radius of the bending piece is less than the allowable value, a reshaping process is added after bending. 3. When the section quality and dimensional accuracy of the workpiece are required to be high, it should be considered to add a trimming process after the punching process or directly use a precision blanking process. 4. The determination of the number of processes should also conform to the company's existing mold making capabilities and the status of stamping equipment. The mold making ability should be able to ensure the corresponding increase in mold processing and assembly accuracy, otherwise the number of processes can only be increased. 5. The number of processes for drawing parts is related to the material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, which can be determined by drawing process calculations. When the rounded corner radius of the drawn part is small or the dimensional accuracy is required to be high, it is necessary to add a shaping process after drawing. 6. In order to improve the stability of the stamping process, it is sometimes necessary to increase the number of processes to ensure the quality of stamping parts. For example, the additional positioning process hole punching of the bent part, the increase of deformation in the forming process, the reduction of the hole punching to transfer the deformed area, and so on. 7. For the processing of precision metal stamping parts, the design stamping parts should be simple in shape and reasonable in structure. In order to simplify the structure of the abrasive tool, our goal is to use the least and simplest stamping parts to process, which is conducive to the stamping operation and not only can improve labor Productivity can also facilitate the organization and production of stamping parts processing, which is conducive to mechanization and automated production.
