Metal Stamping Components

Reasons why metal stamping components may be defective:
Cracking of stamping parts is the most likely quality defect in the process of drawing, flanging, etc., which will directly affect the strength of the part and reduce the service life of the product. Therefore, when there is a cracking problem in the part, it will be scrapped. , This virtually reduces production efficiency and increases production costs. Therefore, effective prevention in the early stage and rapid response to and resolution of defects after occurrence are urgent and necessary.

Cause of cracking
⑴Cracks caused by insufficient tensile strength of the product, such as near the rounded corners of the convex and concave dies, the local force is too large and the rupture occurs.
(2) Cracks caused by insufficient material deformation, cracks near the top of the punch during bulging deformation, or cracks caused by excessive deformation of the flange elongation material.
(3) Aging cracks, that is, material hardening occurs in the forming complex area during the forming process, and the embrittlement phenomenon is accompanied by hardening deformation, which causes the workpiece to break under the action of forming residual stress.
⑷ When the material is deep-drawn and bent, it is bent and folded back to cause cracks, mostly at the convex rib or the die mouth.
(5) Striped cracks, cracks caused by impurities in the material, are generally parallel to the rolling direction of the sheet metal.

cracking solution
⑴In terms of materials: materials with better drawing properties are used.
⑵In terms of strain reduction: 1) Choose a reasonable blank size and shape; 2) Adjust the drawbead parameters; 3) Add auxiliary processes, such as incisions; 4) Improve lubrication conditions; 5) Modify the supplementary surface of the process; Material strength.
