As we all know, unprocessed aluminum has low hardness, and aluminum profiles are used in mechanical automation equipment and assembly line workbenches. So, how do industrial aluminum profiles
withstand loads without deformation?
If the profile is scrapped in the case of bending, it is not worth it, it should not happen, and it can be avoided. So, how to reduce or avoid scrap due to bending?
(1) What role can the straightening of extruded aluminum profiles play: Eliminate the metal stress generated during the extrusion process and control the size of the aluminum profiles.
(2) Extrusion straightening: Straightening is a serious part of the bending of the aluminum profile. The straightener must pay attention to the force used for straightening. If the force is too large, the aluminum profile may be deformed, closed, orange peel, etc. If the force is too small, the profile will not be straightened, resulting in bending.
(3) Extrusion and framing: This link is also very important. After sawing to a certain length, the aluminum profile will be framed. At this time, the framer should pay special attention to: whether the material is large or small, and whether it is a tube the material is still the material drawn from the flat die. Generally speaking, it is not easy to cause bending when the two ends of the large material and the piped material are framed, but the small material and the material pulled from the flat die are easy to bend when the two ends are lifted. Move closer to lift and frame.
(4) Surface treatment on the shelf: After the billet has been aged, the hardness has reached the standard, and the aluminum profile is not so easy to bend, but it is still necessary to pay attention when placing on the shelf. When lifting the material at both ends, try to avoid strong fluctuations up and down, which will also affect the aging. The aluminum profile causes some bending.
