In the precision stamping parts processing need to pay attention to the process matters

Precision stamping parts processed by precision stamping technology have the advantages of large size range, complex shape and high precision, which are widely used in automobile, medical, aviation and other industries.

Technical matters needing attention in the processing of precision stamping parts:

1, the number of precision stamping process and material properties, drawing height, drawing ladder number and drawing diameter, material thickness and other conditions, need to be determined by drawing process calculation.

When the fillet radius of the drawing part is small or the dimensional accuracy is high, a shaping procedure should be added after the drawing.

2, the number of precision stamping parts mainly depends on the complexity of its structure shape, according to the number of bending Angle, 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 processes should also be determined in line with the enterprise's existing mold making capacity and stamping equipment.

Mould making ability should be able to ensure that the machining and assembly accuracy of the mould is improved accordingly. Otherwise, the number of processes can only be increased.

4, in order to improve the stability of precision stamping process sometimes need to increase the number of processes, in order to ensure the quality of precision stamping parts.

For example, additional positioning technology of bending parts hole blanking, deformation reduction hole blanking in forming process to transfer deformation zone and so on.

5. When the section quality and dimensional accuracy of precision stamping parts are required to be high, the dressing process can be added after the blanking process or the precision blanking process can be directly used.

6, punching simple shape of precision stamping parts, using a single process die to complete.

Blanking the workpiece with complex shape, due to the structure or strength of the mold is limited, its internal and external contour should be divided into several parts blanking, need to use multiple stamping process.

There are many precision stamping parts processing process steps, the staff should understand the precautions of each step in detail, correct operation, in order to avoid mistakes, affect the quality of product molding.
