When processing aluminum plates, the most worrying thing is cracking of the aluminum plates. This not only affects the normal work progress, but also causes a waste of aluminum plate resources. How to fundamentally eliminate this situation.
1. Hardness of aluminum plate
The hardness of the aluminum plate is too high and it is easy to crack. This requires choosing a good aluminum material, mainly based on the trademark and conditions of the aluminum. Usually compare 1 series, 3 series and 5 series. Series 6 and 7 are too hard to bend before being annealed to the O state. This is also a quality problem with aluminum plates. Imported materials of the same type of aluminum plates are less likely to crack than domestic materials, but the price of the materials is also much more expensive.
2.Thickness of aluminum plate
An aluminum plate that is too thick is not curved. We need to understand and try to use a little aluminum sheet.
3. Bend R angle
The larger the bending angle R, the higher the success rate, and the larger the R angle, the better.
4. Aluminum plate texture direction
The direction of the bend should be straight, not parallel to the direction of the aluminum plate.
5. For the aluminum plate part in the demand diagram, it is best to bend it after bending according to the process, otherwise it will increase the possibility of bending and cracking.
