Aluminum plate stamping parts in forming crack is how to solve?
Please have a look at
Has 18 years experience in stamping industry engineer told the author, aluminum stamping parts are common in many industry applications, has a high relative requirements, the surface of aluminum plate stampings and formed the size of the request, and bending parts also can produce crack after forming, we how to solve, small author with everyone learning together: aluminum sheet stamping forming parts bending when cracks, will demand the forming radius is too small, in the case of a quality allow can make the radius increased, at the same time requirements to billet surface smooth, no obvious scratches and bumps and so on;
Also require material texture direction and forming in the same direction;
Another method is to eliminate the outside of the burrs, burr can also cause the area of stress concentration, can reduce the bending deformation, to clear the area of burr;
Can also be placed in the forming zone will have burrs on the side of the inside;
