Oem Metal Stamping Parts

Surface defects of oem metal stamping parts:
surface quality defect
The main types of surface quality defects of stamping parts are impact line, slip line, collapse, dark pit, surface distortion, etc.
cause
The impact line and the slip line are mainly due to the surface scratches caused by the friction at the stress concentration point after the sheet metal and the die are in contact during the stamping process. Collapse, dark pit, and surface distortion are mainly due to insufficient deformation of the workpiece, small local material strain, and defects that appear after the release of external forces.

Solution
(1) To eliminate the impact line, you can change the forming fillet, die fillet, increase the drawing depth, and change the binder surface.
(2) To eliminate the slip line, you can change the shape of the product (left and right symmetry), increase the resistance, etc.
(3) To eliminate subsidence and surface distortion, it is necessary to understand the level of stress gradient generated by the part in the deformation zone, and try to ensure the uniformity of the plastic deformation of the product; at the same time, by increasing the resistance, increasing the local forming strain and other means.
conclusion
When a product encounters a quality defect, it is first necessary to conduct an in-depth analysis of the true cause of the problem. Analyze specific problems and formulate feasible rectification plans. In addition, during the implementation of the plan, it is necessary to make a good record of the process, feed back the typical key problems to the early stage, and do a good job in preventing recurrence; in the SE stage, based on the past development experience of stamping parts, through product shape optimization and adjustment, avoid the occurrence of problems, shorten The delivery cycle is guaranteed to ensure the normal development of stamping production and improve production efficiency.
