When bending aluminum materials, the following aspects need to be paid
attention to:

First, material selection and preparation
Aluminum type and status: 1 series, 3 series, 5 series of aluminum is
preferred, because these series of aluminum is more commonly used and relatively
easy to bend. 6 series, 7 series of aluminum hardness is higher, may need to be
annealed to O state to reduce hardness, easy to bend.
Material quality: The same type of aluminum, imported materials are usually
less prone to cracking than domestic materials, but the price will be
correspondingly higher.
Second, processing parameters and technology
Aluminum plate thickness: Choose a thinner aluminum plate for bending as much
as possible, because the thicker aluminum plate is more difficult to bend.
Bending R Angle: Adjust the size of bending R Angle, the larger the R Angle,
the higher the bending success rate. Therefore, if possible, the bending R Angle
should be increased as much as possible.
Bending direction: Ensure that the bending direction is perpendicular to the
aluminum grain direction, rather than parallel, to improve the success rate of
bending and reduce the risk of cracking.
Third, special process requirements
Wire drawing treatment: If the aluminum sheet parts need wire drawing
treatment, it is best to carry out after bending to reduce the probability of
bending cracking.
Fourth, safety and quality control
Operation safety: In the bending process, the operator should wear
appropriate safety protective equipment, and strictly abide by the operating
procedures to ensure safety.
Quality inspection: After bending is completed, strict quality inspection
should be carried out on the product, including size, Angle and surface quality,
etc., to ensure that the product meets the requirements.
In summary, when bending aluminum materials, it is necessary to pay attention
to material selection and preparation, processing parameters and processes,
special process requirements, and safety and quality control. Through reasonable
selection and adjustment, the bending success rate can be improved, the risk of
cracking can be reduced, and the quality and safety of the product can be
ensured.
