In the process of bending the aluminum profile, various forming methods such as bending, bending and roll bending are available. Because the length of the aluminum material for the vehicle is long and the section is large, the section is bent and formed by a roll bending method. The aluminum profile roll bending mainly uses a roll bending machine, a motor of the roll bending machine drives a plurality of rollers which are overlapped up and down to rotate, the aluminum profile starts to gradually pass through the middle of the rollers from the head end, is rolled and bent by the overlapped rollers, gradually rolls and bends the aluminum profile from head to tail into a certain radian, and the radian of the aluminum profile can be adjusted through the position change of the control rollers, so that the required arc-shaped aluminum profile product is finally achieved.
In the roll bending forming process, a three-point roll bending machine is often used, and the three-point roll bending machine rolls and bends the section bar through two parallel X-axis rolls and a Y-axis roll which is positioned on a middle shaft and can move up and down on a Y axis. When roll bending a section with a large section, the phenomenon that the bending verticality of the section is out of tolerance often occurs, and the reason is as follows: the contact points of the three-point roll bending machine and the section bar are 3, and in the traveling process of the section bar, the side surface of the section bar cannot be guided and supported sufficiently, so that the bending plane of the section bar is separated from the three-point roll bending plane, twisting is generated, and the bending verticality is out of tolerance.
