Precision stamping parts processing process should follow the principle

　　1. When the cross section quality and dimensional accuracy of the workpiece are required to be high, it can be considered to add dressing process after the blanking process or directly adopt the precision blanking process.

　　2. The number of processes of bending parts mainly depends on the complexity of its structural shape, according to the number of bending angles, relative position and bending direction. When the bending radius of the bending part is less than the allowable value, a shaping procedure is added after bending.

　　3. The number of drawing parts is related to material properties, drawing height, drawing steps, drawing diameter, material thickness and other conditions, which can only be determined by deep drawing process calculation. When the radius of the drawing part is small or the size accuracy is high, a shaping procedure should be added after drawing.

　　4. The determination of the number of procedures should also conform to the existing mold making capacity and the status of stamping equipment. Mold making ability should be able to ensure the mold processing, assembly accuracy to improve the requirements. Otherwise, only the number of processes can be increased.

　　5. In order to improve the stability of stamping process, it is sometimes necessary to increase the number of procedures to ensure the quality of stamping parts. For example, the additional positioning process of the bending hole system, the addition of deformation in the forming process to reduce the hole blanking to transfer the deformation zone, and so on.

　　For metal stamping parts processing, stamping parts design to simple shape, reasonable structure, in order to simplify the structure of grinding tool, the goal, with the least, the most simple stamping parts processing, in this case, is advantageous to the stamping operations, not only can improve labor productivity, also can facilitate the production of stamping parts processing, production mechanization and automation.
