Precision Stamping Parts Must Pay Attention To 7 Points

What are precision stamping parts?We can understand that in the process of processing the thickness of the same parts, in fact is the sheet metal hardware, stamping, bending, stretching and other operations can be processed, we in the process of precision stamping parts to pay attention to what things?Let's see.

1. With a single process die to blunt some simple parts.Use multiple stamping processes to blanch complex parts, and the mold structure or strength is limited, its internal and external contour should be divided into several parts blanking.For the workpiece with higher flatness requirement, it can add a leveling operation after the blanking process.

2. Whether the complexity of structural shape determines the number of processes to be used for bending parts, which is determined by the number of bending angles, relative position and bending direction.So why add a plastic procedure after bending sometimes?This is because the bending radius of the bending piece is less than the allowable value.

3. When we add finishing process or directly adopt precision blanking process after blanking process, it is because of the high requirements on the section quality and dimension accuracy of the workpiece

4. For the metal stamping parts processing, our goal, with the least, the most simple stamping parts processing, the design of the stamping parts to the shape of simple, reasonable structure, so conducive to the operation of stamping, not only can improve labor productivity, and is conducive to the stamping parts processing organization production and mechanization and automation production.

5. We want to according to the enterprise's existing capacity and stamping equipment to determine the number of procedures.And the ability to mold must ensure that the mold processing and assembly accuracy to the standard, otherwise only to increase the number of procedures.

6. The properties of materials, the height of drawing, the number of drawing steps, the diameter of drawing, the thickness of drawing and other conditions determine the number of drawing parts. However, the number can only be determined by the calculation of drawing technology.If the radius of the drawing part is small or the size accuracy is high, it is necessary to add a plastic procedure after drawing.

7. To improve the stability of stamping process, we need to increase the number of procedures to ensure the quality of stamping parts.For example, additional positioning process hole punching system for bending parts, adding deformation in the forming process to reduce the hole punching to transfer the deformation zone, etc.
