The aluminum profile shell is a more common one. The aluminum profile of the shell generally has higher decorative requirements, and some shells are thinner and others are thinner. So what should be paid attention to when extruding the aluminum profile shell? The following is an introduction and analysis.
surface treatment
1. After the raw material is processed, the hardness of the blank reaches the standard, and the aluminum profile is not easy to bend. However, when placing it on the shelf, it is necessary to pay attention to the hanging materials at both ends, and try to avoid violent fluctuations up and down, which will cause certain bending of the aging aluminum shell.
2. The aluminum profile shell is made by processing the aluminum profile obtained during drawing. The stretched aluminum profile has high flexibility and can be cut to any length. Generally, there are circuit board slots inside. As long as it is plugged directly into the board, no fixing is required. Compared with other types of housings, it has unparalleled convenience and broader application prospects.
squeeze and pull
Straightening is a very important part of the aluminum shell manufacturing process, and the straightening machine must pay attention to the strength used for straightening. If the force is too large, it may cause problems such as deformation and necking of the aluminum profile; if the force is too small, it may not be straightened, resulting in bending. So we have to control the intensity.
Squeeze the frame
This link is also very important. After sawing to a fixed length, the aluminum profile is framed. At this time, it is necessary to pay attention to: whether the material is large or small, whether it is a material with a tube or drawn with a flat die. Generally speaking, it is not easy to bend the racks at both ends of the material with a pipe, but the material drawn from the small material is easy to bend at both ends. At this time, it should be lifted from both ends to the middle and framed. But some aluminum profiles, such as shutters, window panels, glands, etc., must be placed on the aged aluminum profiles and then hung in the frame.
The above are the matters needing attention when processing the extruded aluminum shell, and it is recommended that the operator pay more attention to the condition of the profile to avoid local or point-like deformation, twisting, spiral and other defects in the aluminum profile.
