[0002] In the field of steel bar processing, steel bars are usually bent by steel bar bending machines to bend them into various required components. During the bending process of steel bar bending machines, auxiliary devices are needed to assist in bending.

[0003] A search revealed Chinese Patent Publication No. CN221434763U, which discloses an auxiliary device for bending reinforcing bars in construction engineering, belonging to the field of reinforcing bar bending technology. The device includes a base, with a mounting frame fixedly connected to the top. A first rotating shaft passes through the inner wall of the mounting frame via bearings, and a first conveying wheel is fixedly connected between the first rotating shafts. A hydraulic rod is fixedly connected to the top of the inner wall of the mounting frame, and a lifting frame is fixedly connected to the bottom of the hydraulic rod. A second rotating shaft passes through the lifting frame via bearings, and a second conveying wheel is fixedly connected between the second rotating shafts. A mounting base is fixedly connected to the bottom of the base. The hydraulic rod extends and retracts, causing the lifting frame and the second conveying wheel to rise and fall, thereby freely adjusting the distance between the first and second conveying wheels according to the diameter of the reinforcing bar. This allows for auxiliary conveying of reinforcing bars of different diameters, improving the practicality of the device. The entire device has a reasonable structure, is easy to use, and is highly practical.

A pressure sensor 9 is fixedly installed on the top of the mounting plate 8, and a lifting plate 10 is fixedly connected to the top of the pressure sensor 9. The pressure sensor 9 works in conjunction with the hydraulic push rod 7. A driven double-cone conveying roller assembly 11 is movably connected inside the lifting plate 10. The driven double-cone conveying roller assembly 11 has the same shape as the driving double-cone conveying roller 5, and both surfaces are bonded with a rubber layer. Rubber anti-collision blocks 23 are provided at the four corners of the bottom of the lifting plate 10. The bottom of the rubber anti-collision blocks 23 is fixedly connected to the top of the base plate 1. The rubber anti-collision blocks 23 limit the downward movement of the lifting plate 10, preventing the mounting plate 8 from hitting the base plate 1 due to excessive downward movement of the lifting plate 10. Sliding strips 24 are slidably connected to both the front and rear sides of the lifting plate 10. The surfaces of the sliding strips 24 are fixedly connected to the inner wall of the cover plate 3. The sliding strips 24 limit the movement of the lifting plate 10, preventing it from shaking during movement. Limiting blocks 25 are fixedly connected to the top of both the front and rear sides of the inner wall of the cover plate 3. The limiting blocks 25 are located at the top of the lifting plate 10, limiting its upward movement and preventing it from colliding with the active double cone conveyor roller 5, thus improving the safety of the active double cone conveyor roller 5.

[0035] Reference Figure 1-3 The rebar feeding assembly includes a storage box 12, which is located on the top left side of the base plate 1. A support group 13 is fixedly connected to the rear side of the bottom of the storage box 12. An electric linear guide rail 14 is fixedly connected to the bottom of the support group 13. The bottom of the electric linear guide rail 14 is fixedly installed on the top of the base plate 1. An electric push rod 15 is fixedly installed on the front and rear left sides of the storage box 12. A T-shaped plate 16 is fixedly connected to the output end of the electric push rod 15. A push rod 17 is fixedly connected to the bottom right side of the T-shaped plate 16. A push block 18 is fixedly connected to the right side of the push rod 17.

Through the cooperation of the storage box 12, the support group 13, the electric linear guide rail 14, the electric push rod 15, and the T-shaped plate 16, the rebar on the top of the arc-shaped rebar guide plate 6 can be quickly pushed to the feeding assembly, achieving the effect of rapid rebar feeding. An L-shaped positioning plate 19 is fitted onto the right side of the push rod 17. The right side of the L-shaped positioning plate 19 is fixedly connected to the left side of the storage box 12. The L-shaped positioning plate 19 limits the push rod 17, preventing it from shaking and improving its stability. A protective plate 20 is fixedly connected to the left side of the storage box 12. A T-shaped plate 16 is located at the bottom of the protective plate 20. The protective plate 20 isolates the T-shaped plate 16, preventing it from colliding with the user and improving user safety.

[0036] Reference Figure 1-3A stabilizing column assembly 21 is fixedly connected to the top left side of the substrate 1. The top of the stabilizing column assembly 21 is in contact with the surface of the storage box 12. The stabilizing column assembly 21 provides auxiliary support for the storage box 12, which can prevent the storage box 12 from shaking during long-term use. A tool placement slot 22 is provided on the front left side of the substrate 1. Tools and items are stored in the tool placement slot 22 for easy access by the user.

[0037] Working principle: The user first places the steel bars of appropriate length neatly inside the storage box 12, allowing the steel bars to fall sequentially through the opening at the bottom of the storage box 12 onto the top of the arc-shaped steel bar guide plate 6. The electric push rod 15 is activated, and its output end drives the push rod 17 and push block 18 to the right via the T-shaped plate 16. The push block 18 pushes the steel bars at the top of the arc-shaped steel bar guide plate 6 to the right, causing the right side of the steel bars to enter the inner side of the active double-cone conveying roller 5 and the driven double-cone conveying roller group 11. Then, the electric push rod 15 drives the push block 18 to return to its original position and activates the hydraulic push rod 7. The output end of the hydraulic push rod 7 drives the mounting plate 8, pressure sensor 9, and lifting plate 10 to move upwards. The lifting plate 10 drives the driven double-cone conveying roller group 11 to move upwards in conjunction with the active double-cone conveying roller group 6. The conical conveying roller 5 clamps the right side of the rebar, and the pressure sensor 9 monitors the clamping pressure to prevent excessive clamping pressure from damaging the equipment. After the rebar is clamped, the reduction motor 4 is started simultaneously. The output end of the reduction motor 4 drives the active double conical conveying roller 5 to rotate and cooperates with the driven double conical conveying roller group 11 to stably convey the rebar to the rebar bending machine for bending. When the length of the rebar to be bent is too long to be placed inside the storage box 12, the electric linear guide 14 is started. The electric linear guide 14 drives the storage box 12 and the electric push rod 15 to move backward through the bracket group 13, exposing the arc-shaped rebar guide plate 6. The user can manually place the rebar on the top of the arc-shaped rebar guide plate 6 and start the hydraulic push rod 7 and the reduction motor 4 to convey the rebar.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
