In the production process of aluminium alloy shell, due to various reasons, sometimes inevitably damaged situation. So how to prevent damage to the aluminium alloy shell?
Preventive measures to avoid damage to the aluminium alloy shell:
1. Straightening by extrusion molding
Straightening is a very critical stage in the manufacturing process of aluminium alloy shell. Straightening workers must pay attention to the commonly used amplitude of straightening. Excessive energy is likely to cause deformation, edge closing, orange peel and other problems to the aluminium alloy shell. If the energy is too small, it is likely to bend again, resulting in bending. Therefore, to grasp the good range. aluminium intermediate alloy.
2. Extrusion molding and framing
This stage is also more critical, after sawing the length of the length, the aluminium alloy shell needs to be framed. At this time, the framing worker needs to pay attention to: whether this material is large material or ingredient, whether it is material with pipe or material pulled out by the plan die. Generally speaking, it is not easy for large material and material with pipe to be framed on both sides, but it is easy for materials pulled out by ingredients and plan die to be bent on both sides. At this time, material lifting and framing should be carried out from both sides to the middle.
3. Release of metal surface treatment
The embryo is time-sensitive and has qualified strength, so the aluminium alloy shell is not easy to bend. However, attention should be paid to the fact that when lifting materials on both sides, the fluctuation of up and down force should be minimized, and the fluctuation will also lead to bending of the time-sensitive aluminium alloy shell.
