What are the principles that should be followed in the processing of precision stamping parts

Precision stamping parts are thin-plate hardware, that is, parts that can be processed by means of stamping, bending, stretching, etc. A general definition is a part with constant thickness during processing. So what are the principles to follow when working with precision stamping parts? The following article is for everyone to answer.

     The principles that should be followed in the processing of precision stamping parts:

     1. The workpiece with simple shape is punched out, and the workpiece with complicated shape is punched out. Because the structure or strength of the mold is limited, the inner and outer contours should be divided into several parts and punched. For workpieces with higher flatness requirements, a leveling process can be added after the blanking process.

     2. The number of processes of the curved member depends mainly on the complexity of its structural shape, depending on the number of bending angles, relative position and bending direction. When the bending radius of the bending member is less than the allowable value, a shaping process is added after the bending.

     3. When the cross-section quality and dimensional accuracy of the workpiece are required to be high, it should be considered to increase the dressing process after the blanking process or directly adopt the precision blanking process.

     4. The determination of the number of processes should also be in accordance with the existing molding capabilities of the enterprise and the status of the stamping equipment. The mold-making ability should ensure the corresponding improvement of the mold processing and assembly precision, otherwise the number of processes can only be increased.

     5. The number of processes for drawing the parts is related to the material properties, the height of the drawing, the number of steps, the diameter of the drawing, the thickness of the material, etc., and can be determined by drawing the process. When the depth of the fillet is small or the dimensional accuracy is high, a shaping process is required after the 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 the stamping parts. Additional positioning process hole punching such as bending members, increased deformation in the forming process, reduction of hole punching to transfer deformation zones, and the like.


     7. For the processing of metal stamping parts, the design of stamping parts should be simple in shape and reasonable in structure. In order to simplify the structure of the grinding tools, our goal is to process with the least and simplest stamping parts, which is beneficial to the operation of stamping, which can not only improve labor. Productivity can also facilitate tissue production of stamped parts, facilitating mechanization and automated production.

     The above is a description of the principles that should be followed in the processing of precision stamping parts. I hope that everyone will follow the above seven principles when processing precision stamping parts.http://www.dgcncstamping.com/
