The first bending roller 2, the second bending roller 3, and the third bending roller 4 all include a roller shaft and a wave roller surface fixedly mounted on the roller shaft, which belongs to the prior art and will not be described in detail here. The distance between the first arc bending roller 2 and the second arc bending roller 3 is the same as the distance between the first arc bending roller 2 and the third arc bending roller 4. The first arc bending roller 2 is located between the second arc bending roller 3 and the third arc bending roller 4 and the upper and lower positions are adjustable. During the adjustment process, the distance between the first arc bending roller 2 and the second arc bending roller 3 is equal to the distance between the third arc bending roller 4.

[0024] The working principle of this embodiment is:

[0025] When the wave plate bends, the bending roller power device operates, and the second bending roller 3 and the third bending roller 4 act as active rollers, actively rotating in the same direction, and the wave plate enters between the first bending roller 2 and the second bending roller 3, and the first bending roller 2 acts as a passive roller and passively rotates following the wave plate, and the wave plate continues to move between the first bending roller 2 and the third bending roller 4, so that the surface of the wave plate bends to form an arc; when the curvature needs to be adjusted, the lifting and adjusting device is started, and the two sliding roller frames 6 are driven to rise or fall along the corresponding fixed roller frames 5 through the lifting screw assembly 7, that is, the first bending roller 2 is driven to rise or fall, so as to adjust the bending curvature.

[0026] The sliding roller frame 6 in the utility model is slidably installed on the fixed roller frame 5, and the lifting screw assembly 7 is connected to the bottom end of the sliding roller frame 6, so that the lifting screw assembly 7, the lifting adjustment device and other structures can be arranged at the lower part of the arc bending machine without occupying the upper space of the arc bending machine, which can effectively reduce the overall height of the equipment, occupy a small space, and has a beautiful appearance.
