Its basic operating principle is to use bending rollers to forcibly bend hot strip steel to the desired curvature radius, achieving the desired bending shape. The bending rollers consist of an upper roller, a lower roller, and side rollers. The movement of the upper and lower rollers bends the metal sheet, supported by the side rollers. However, adjusting the bending angle with existing bending rollers requires adjusting the vertical position of the upper and lower rollers separately, a time-consuming and labor-intensive process that impacts bending efficiency.

[0006] Furthermore, side rollers are provided at the rear ends of the upper bending roller and the lower bending roller; and the side ends of the side rollers are connected to the steel ring forming machine body through transmission shafts.

[0007] Furthermore, the transmission wheel assembly is composed of a belt and two sets of transmission wheels; and the two sets of transmission wheels are axially connected to the adjustment screws in the adjustment frame grooves on the left and right sides respectively.

[0009] Furthermore, the inner sides of the fixed shaft and the movable shaft are movably sleeved with the transmission shaft via bearings, and the fixed shaft and the movable shaft are in contact with the inner groove wall of the adjustment frame.

[0010] Furthermore, a driving block is embedded and fixed inside the front extension end of the movable shaft, and a small motor is fixed on the lower front surface of the fixed shaft.

[0018] Reference Figures 1 to 4 As shown, the utility model provides a bending roller of a steel ring forming machine, comprising: an upper bending roller 1, a lower bending roller 11 and an adjusting frame 2. The lower bending roller 11 is provided at the lower end of the upper bending roller 1, and the upper bending roller 1 and the lower bending roller 11 are connected to the adjusting frame 2 on the left and right sides.

[0019] The left and right sides of the upper pressure bending roller 1 are connected to the movable shaft 31 through the transmission shaft 13, and the left and right sides of the lower pressure bending roller 11 are connected to the fixed shaft 3 through the transmission shaft 13. The outer end surface of the fixed shaft 3 is fixed with a distance sensor 33, and the front side plate of the fixed shaft 3 is installed with an adjusting screw 4. The surface of the adjusting screw 4 is connected to the movable shaft 31 through the driving block 41, and the lower end shaft of the adjusting screw 4 is connected to the transmission wheel assembly 42 and the small motor 43.

[0020] During use, when steel plates of different thicknesses are press-bent, the movable shaft 31 is driven up and down by rotating the adjusting screw 4 on the front side of the fixed shaft 3, and the spacing of the upper bending roller 31 is adjusted with the lower bending roller 11 as the positioning base point, so that the two ends of the upper bending roller 1 move up and down synchronously, which is convenient for quickly adjusting the spacing between the upper and lower bending rollers, and convenient for adjusting the amplitude of the two ends of the bending roller to be consistent, ensuring the force balance of the bending surface of the steel ring, and avoiding the influence of the inconsistent hydraulic lifting and lowering of the two ends of the bending roller on the bending effect of the steel ring.

[0021] In this embodiment, side rollers 12 are provided at the rear ends of the upper bending roller 1 and the lower bending roller 11 ; and the side ends of the side rollers 12 are connected to the steel ring forming machine body through the transmission shaft 13 .

[0022] As a preferred embodiment, the side rollers 12, the upper bending roller 1, and the lower bending roller 11 form a complete bending roller for forming a steel ring. When the steel plate passes through the gap between the upper bending roller 1 and the lower bending roller 11, it is bent into a ring shape by the support of the side rollers 12. The side end of the lower bending roller 11 is connected to the bearing structure and hydraulic cylinder of the steel ring forming machine. The specific connection structure is an existing mature technology and will not be described in detail. The hydraulic cylinder can drive the hydraulic cylinder as a whole to move up and down.

[0023] In this embodiment, the drive wheel assembly 42 consists of a belt and two sets of drive wheels, each of which is axially connected to the adjustment screws 4 within the grooves of the left and right adjustment frames 2. A small motor 43 is located within the groove of the adjustment frame 2 on the right side of the upper bending roller 1. The control panel 21 is mounted on the front surface of the adjustment frame 2.

[0024] As a preferred embodiment, a drive wheel assembly 42 synchronously connects the two sets of adjustment screws 4 on the left and right sides of the upper and lower bending rollers 1, 11. These are driven by a small motor 43, ensuring that the two ends of the bending rollers move with the same amplitude and that the bending rollers are evenly stressed when bending the steel plate. A control panel 21 is used to control the start and stop and rotation speed of the small motor 43.

[0025] In this embodiment, the inner sides of the fixed shaft 3 and the movable shaft 31 are movably connected to the transmission shaft 13 via bearings 32. The fixed shaft 3 and the movable shaft 31 are in contact with the inner groove wall of the adjustment frame 2. A driving block 41 is embedded and fixed within the front extension of the movable shaft 31, and a small motor 43 is fixed to the lower front surface of the fixed shaft 3.

[0026] As a preferred embodiment, the transmission shaft 13 can rotate inside the fixed shaft 3 and the movable shaft 31 through the bearing 32 without affecting the vertical movement of the fixed shaft 3 and the movable shaft 31. The driving block 41 facilitates converting the rotational motion of the adjusting screw 4 into linear motion, thereby driving the movable shaft 31 to move.

[0027] In this embodiment, the fixed shaft 3, the movable shaft 31, the adjusting screw 4, the driving block 41, the transmission wheel assembly 42 and the small motor 43 constitute the spacing adjustment mechanism of the upper bending roller 1 and the lower bending roller 11.

[0028] As a preferred embodiment, the spacing adjustment mechanism of the upper bending roller 1 and the lower bending roller 11 facilitates quick adjustment of the spacing between the upper and lower bending rollers, facilitates the adjustment amplitude at both ends of the bending roller to be consistent, ensures the force balance of the steel ring bending surface, and avoids the impact of inconsistent hydraulic lifting and lowering at both ends of the bending roller on the steel ring bending effect.

[0029] The bending roller of the steel ring forming machine of the present invention can effectively solve the problem that when adjusting the bending angle of the existing bending roller, the vertical positions of the upper roller and the lower roller need to be adjusted separately, which is time-consuming and labor-intensive and affects the bending efficiency. It is convenient to quickly adjust the distance between the upper and lower bending rollers, and facilitate the adjustment of the amplitude at both ends of the bending roller to be consistent, thereby ensuring the force balance of the bending surface of the steel ring and avoiding the influence of inconsistent hydraulic lifting at both ends of the bending roller on the bending effect of the steel ring. The utility model is suitable for the bending roller of the steel ring forming machine.
