[0002] Window bodies are indispensable components of buildings. In the production of doors and windows, doors and windows need to be bent, and the bending angle and depth need to be set according to actual conditions. Generally, a bending machine is used to bend aluminum alloy doors and windows. Existing bending machines generally pass aluminum alloy doors and windows through the transmission rollers on two driven rods and the transmission roller on an active rod. The two driven rods are located on the same side of the aluminum alloy doors and windows, and the active rod is located on the other side of the aluminum alloy doors and windows. The controller controls the motor in the drive mechanism to make the active rod continuously rotate forward and reverse. During this process, the controller controls the transmission mechanism to gradually make the drive mechanism and the active rod move close to the driven rod, so that the aluminum alloy doors and windows gradually bend.

[0003] For example, the utility model with application number CN202122755524.X discloses a bending machine for producing aluminum alloy doors and windows, comprising a working plate, a cylinder, an active rod, an active rod clamp, a driven rod moving device, a driven rod and a driven rod clamp, wherein the cylinder is fixed to the working plate, the active rod clamp is fixedly connected to the piston rod of the cylinder through the active rod, the driven rod moving device is slidably connected to the working plate through a horizontal electric slide rail, the horizontal electric slide rail is horizontally placed, the driven rod clamp is fixedly connected to the driven rod moving device through the driven rod, the number of the driven rod moving devices is two, and the two driven rod moving devices are respectively located on the left and right sides of the cylinder.
