In our daily life, we often see brightly colored and uniquely shaped plates, which are the effect of aluminum plates after bending. However, the aluminum plate is easy to break after bending, or burst good anodizing after bending, the following are the factors that affect the bending of the plate.
1, the hardness of the aluminum plate: aluminum plate is too hard, it is easy to fracture. This requires a good selection of aluminum plate, mainly depending on the grade and state of aluminum. General 1 series, 3 series, 5 series are more commonly used; 6 series, 7 series of hardness is too high, to do annealing treatment to O state before bending.
2, the thickness of the aluminum plate: too thick aluminum plate is not good bending, try to use thinner aluminum plate.
3, the size of the bending R angle: the larger the bending R angle, the higher the success rate, so try to bend the R angle as large as possible.
4, aluminum plate grain direction: bending direction should be perpendicular to the direction of the aluminum plate grain, not parallel.
5, the need to draw the aluminum plate parts, in the process is best to allow bending and then drawing forming, otherwise it will increase the probability of bending fracture.
The above is about the aluminum plate bending process considerations introduced here, the main adjustment of these aspects, you can avoid the phenomenon of aluminum plate bending fracture.
