How to prevent hardware stretch parts from wrinkling in stamping plant
Stamping molding plant is good at processing metal stretching parts, stainless steel stretching parts, metal stretching parts and other stamping parts. Wrinkling often occurs in the drawing process. How does the manufacturer prevent the wrinkling?
Stamping factory first to analyze the reasons for the wrinkling of hardware stretching parts: the main reason for wrinkling of drawing parts is that the thickness of the metal material is not thick enough, so the natural force is relatively small. This situation is easy to lead to tension wrinkling; the stretching coefficient is small, and it does not select the appropriate stretching coefficient according to the characteristics of the blank, so that the deformation is too large It is difficult to control the deformation, resulting in deformation; the damaged blank holder ring can not give the blank the same pressure, which leads to the workpiece wrinkling.
The measures should be taken: the drawing blank should be thicker, so that the material can bear the relative pressure in the drawing process, so as to achieve the purpose of no deformation and wrinkling; select the tensile coefficient corresponding to the metal material, so that the deformation can be controlled, and the blank holder should be repaired and replaced in time, so that the blank will not be deformed easily.
