When the aluminum plate bends, it can break easily, or when it is bent, it will burst through anodizing, and many of the sheet metal processing enterprises are confused, so how can we not break?
First of all, we need to know the main reasons for the fracture of the aluminum plate and the following points:
1.Hardness of aluminum plate
The aluminum plate is too hard and easy to break.This requires the selection of good aluminum, mainly aluminum plate number, and status.General 1 series, 3 series, 5 series are commonly used; The hardness of 6 series and 7 series is too high, so it is easy to bend after annealing treatment to O state.And the quality of the aluminum.
2. Thickness of aluminum plate
Too thick aluminum plate is not good to bend, use thinner aluminum plate as far as possible.
3. The size of bend R Angle
The larger the Angle, the higher the success rate is, so the larger the Angle of R is.
4. Aluminum plate grain direction
The bending direction should be perpendicular to the direction of the aluminum plate, not parallel.
5. It is necessary to draw the aluminum parts of the wire drawing.
In the case of the process, it is better to bend and pull shape, otherwise, the probability of bending fracture will be increased.
In the above aspects, the bending fracture of aluminum plate will be solved better.
