Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 The adjustable bending device for steel ring processing shown in the figure comprises a U-shaped base 1, two slide grooves are provided on the top of the U-shaped base 1, slide shafts 2 are fixedly installed on the opposite inner walls of the two slide grooves, side clamps 3 are slidably installed on the two slide shafts 2, compression components are arranged on the opposite sides of the two side clamps 3, slide holes are provided on the sides of the two side clamps 3, sliders 5 are slidably installed in the two slide holes through the adjustment components, limit plates 8 are fixedly installed on the opposite sides of the two sliders 5, lifting grooves are provided on the opposite inner walls of the U-shaped base 1, a transmission cavity is provided in the U-shaped base 1, and two screws 11 are rotatably installed on the bottom inner wall of the transmission cavity The top ends of the two screw rods 11 are rotatably mounted on the top inner walls of the two lifting grooves respectively, and the two screw rods 11 are connected by a transmission assembly. The lifting blocks 10 are threadedly mounted on the two screw rods 11, and the opposite sides of the two lifting blocks 10 are rotatably mounted with a rotating shaft 15. A motor groove is opened on the side of one of the lifting blocks 10, and a driving motor 16 is fixedly installed in the motor groove. The output shaft of the driving motor 16 is fixedly connected to the end of the rotating shaft 15, and a lower bending wheel 17 is fixedly sleeved on the rotating shaft 15. A U-shaped top plate 18 is fixedly mounted on the top of the U-shaped base 1, and an upper bending wheel 20 is arranged on the bottom of the U-shaped top plate 18 through a lifting assembly.

[0023] By means of the above structure, when in use, first slide the side clamps 3 to both sides, and then place the material on the top of the U-shaped base 1, and then loosen the two side clamps 3, and the elastic action of the two compression components drives the two side clamps 3 to reset, thereby realizing the function of fixing the two sides of the material, and then the adjustment component drives the limit plate 8 to move downward to limit the top of the material, which effectively avoids the warping phenomenon on both sides of the material during the bending process and improves the bending effect. When the bending angle needs to be adjusted, the two screws 11 are driven to rotate synchronously through the transmission component, and then the two lifting blocks 10 and the lower bending wheel 17 are driven to rise and fall synchronously to a suitable position, thereby realizing the adjustment function of the bending angle, effectively adapting to different needs, and the adjustment operation is simple and convenient, and it is highly practical.

[0024] like Figure 3 As shown, the compression assembly includes a compression spring 4, one end of which is fixedly mounted on the side of the side clamp 3, and the other end of the compression spring 4 is fixedly mounted on the side inner wall of the slide groove. The advantage of this arrangement is that, through the arrangement of the compression spring 4, when the limit on the side clamp 3 is released, the side clamp 3 can be driven by its elastic action to achieve a reset function.

[0025] Specifically, when the two side clamps 3 are moved to both sides, the two compression springs 4 will be stretched. After the material is placed, the side clamps 3 are released. The elastic action of the compression springs 4 can drive the side clamps 3 to achieve a reset function, thereby facilitating the clamping of both sides of the material.

[0026] like Figure 3 As shown, the adjustment assembly includes a threaded rod 6, the bottom end of the threaded rod 6 is rotatably mounted on the bottom inner wall of the sliding hole, the top end of the threaded rod 6 extends to the outside of the side clamp 3 and is provided with an operating unit, and the slider 5 is threadedly mounted on the threaded rod 6. The advantage of this arrangement is that the lifting function of the slider 5 can be realized through the arrangement of the threaded rod 6.

[0027] Specifically, when the threaded rod 6 rotates, the threaded action can drive the slider 5 to achieve lifting movement, thereby driving the limit plate 8 to move synchronously, limiting the top of the material, and effectively avoiding the warping phenomenon on both sides during bending.

[0028] like Figure 3 As shown, the operating unit includes a knob 7, the bottom end of which is fixedly connected to the top end of the threaded rod 6. The advantage of this arrangement is that the threaded rod 6 can be conveniently rotated by the arrangement of the knob 7.

[0029] Specifically, when the threaded rod 6 needs to be rotated, the staff can realize the convenient rotation function of the threaded rod 6 by rotating the knob 7, which is convenient for the staff to actually operate.

[0030] like Figure 3As shown, the bottom of the limit plate 8 and the side of the side clamping plate 3 are both provided with a protective pad 9. The advantage of such a setting is that, through the setting of the protective pad 9, the material can be protected during movement to prevent wear caused by friction.

[0031] Specifically, by arranging the protection pads 9 on the sides of the side clamping plates 3 and the bottom of the limiting plates 8, the protection pads 9 can protect the material when it slides, thereby preventing the material from being worn due to friction and improving the protection.

[0032] like Figure 4 As shown, the transmission assembly includes two sprockets 12, and the two sprockets 12 are fixedly sleeved on the two screw rods 11 respectively. A chain 13 is installed on the two sprockets 12 in meshing relationship with each other. An equipment groove is provided on the bottom inner wall of the transmission cavity, and a driving motor 16 is fixedly installed in the equipment groove. The output shaft of the driving motor 16 is connected to the bottom end of one of the screw rods 11. The advantage of such an arrangement is that, through the arrangement of the two sprockets 12 and the chain 13, the two screw rods 11 can be driven to rotate synchronously, thereby avoiding the phenomenon of the rotating shaft 15 being stuck during lifting.

[0033] Specifically, when the driving motor 16 drives one of the screw rods 11 to rotate, the meshing action of the two sprockets 12 and the chain 13 drives the other screw rod 11 to rotate synchronously, so that the two lifting blocks 10 are lifted and lowered synchronously, avoiding the jamming of the rotating shaft 15 during lifting and lowering. The bending angle can be adjusted by adjusting the height of the rotating shaft 15 and the lower bending wheel 17, which has strong practicality.

[0034] like Figure 1 and Figure 2 As shown, the lifting assembly includes a hydraulic cylinder 19, which is fixedly installed on the top of the U-shaped top plate 18. The output end of the hydraulic cylinder 19 passes through the U-shaped top plate 18 and is provided with a mounting plate. The opposite sides of the mounting plate are jointly rotatably installed with a rotating rod. The upper bending wheel 20 is fixedly sleeved on the rotating rod. A control panel 21 is provided on the side of the U-shaped top plate 18. The control panel 21 is electrically connected to the lifting motor 14, the drive motor 16, and the hydraulic cylinder 19. The advantage of such a setting is that through the setting of the hydraulic cylinder 19, the upper bending wheel 20 can be driven to move downward to realize the bending operation, and through the setting of the control panel 21, the lifting motor 14, the drive motor 16, and the hydraulic cylinder 19 can be conveniently controlled.

[0035] Specifically, through the setting of the control panel 21, convenient control of the lifting motor 14, the driving motor 16, and the hydraulic cylinder 19 can be achieved, which is convenient for the staff to actually operate, and the operation of the hydraulic cylinder 19 can drive the upper bending wheel 20 to move downward to bend the material, with high bending efficiency and relative stability.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
