Technical Keyword: The influence of material thickness on stamping parts processing

Background:

Material thickness has a direct effect on stamping process arrangement. For example, for this part, due to the thickness of the material, under the influence of the large gap, the accuracy is low and the quality is rough. It is necessary to meet the accuracy requirements through the refurbishment process.

For this part with material thickness 4.0mm, which has a great influence on the stamping deformation force. Material thickness is proportional to stamping variation. The thicker the material, the greater the stamping deformation force. According to the size of the deformation force, we choose the right stamping equipment and strength of the die.

The dimensional accuracy of stamping parts will be affected by spring back, as well as the impact of the cutting surface.  However, no matter in bending, drawing and blanking processes, the spring back of the stamping parts is greater for thin material than thick material.  Although the precision of thin material parts is reduced because of the larger Spring back.  So the general trend is that the dimensional accuracy decreases with the increase of material thickness.

Conclusion:

In generally, the influence of material thickness on stamping process, parameters, die structure, dimensional accuracy and stamping deformation force.  In the actual production process, if we find problems, we will immediately make targeted treatment, to ensure that part quality to meet customer requirements, and ensure the quality of the tool.
