Description

Technical Field

[0001] This utility model relates to the technical field of rebar threading devices, specifically to a rebar threading device for a rebar cage welding machine. Background Technology

[0002] Before welding with a steel reinforcement cage welding machine, the round steel or threaded steel bars that make up the longitudinal bars of the steel reinforcement cage need to be inserted into the round holes on the reinforcing bar plate or auxiliary reinforcing bar plate.

[0003] The existing rebar cage welding machine uses a rebar threading device to position and fix the threading plate through a mold groove and a pressing groove, and a limiting groove to limit the rebar, ensuring precise alignment between the rebar and the hole. This facilitates the mechanical gripper to drive the rebar through the hole. Although the above method can achieve the device's conveying and threading of the rebar, the rebar is prone to wear during the conveying process, leading to increased repair costs later. At the same time, the rebar has poor stability during conveying, and when threading the rebar, one end of the rebar is prone to deviation from the hole position, affecting the accuracy and smoothness of threading.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-2As shown, the rebar threading device of a rebar cage welding machine in this embodiment includes a base plate 4. Two support plates 15 are symmetrically installed on both sides of the top of the base plate 4. Four support rods 3 are fixed at the four corners of the top of the base plate 4. A top plate 1 is set at the top of the support rods 3. Four hydraulic jacks 10 are symmetrically installed on both sides of the bottom of the top plate 1. The telescopic ends of the hydraulic jacks 10 are connected to support plates 11. Motors 12 are installed on the outer walls of both support plates 11 and support plates 15. A drive shaft 2 is set at the power output end of the motor 12. A conveying roller 9 is fixed on the drive shaft 2. The motor 12 drives the drive shaft 2 to rotate, realizing the rotation of the conveying roller 9 on the drive shaft 2. The two conveying rollers 9 rotate relative to each other, realizing the conveying of rebar. Anti-slip rubber pads 8 are provided on the outer walls of the conveying rollers 9. The design of the anti-slip rubber pads 8 prevents slippage when conveying rebar. The conveyor roller 9 rolls and drives the steel bar to move. At the same time, the steel bar makes direct contact with the anti-slip rubber pad 8 on the transmission surface of the conveyor roller 9, which can avoid rigid friction between the steel bar and the device. With the compression pad 19 limiting the steel bar, the integrity of the steel bar surface before the hole is pierced can be effectively guaranteed, avoiding the problem of repairing the steel bar later. The bottom plate 4 is symmetrically set with limit plates 6 on both sides of the conveyor roller 9. Limit plates 6 have limit holes 5. Two electric telescopic rods 18 are symmetrically installed in the limit holes 5. The telescopic ends of the electric telescopic rods 18 are connected to clamping plates 17. The inner side wall of the clamping plate 17 is provided with compression pads 19. The electric telescopic rods 18 drive the limit plates 6 to move relative to each other, realizing the limiting support of the steel bar by the limit plates 6. With the design of the compression pads 19, the stability of the steel bar can be effectively guaranteed.

[0025] like Figures 1-2 As shown, in this embodiment, a support plate 4 20 is fixed on the base plate 4 between the conveying rollers 9. An electric telescopic rod 16 is fixed at the top of the support plate 4 20. The telescopic end of the electric telescopic rod 16 is connected to a support plate 3 7. A slot 14 is opened at the top of the support plate 2 15. A plug block 13 is fixed at the bottom of the support plate 1 11. The device positions and fixes the reinforcing bar through the conveying rollers 9 and the limiting plate 6. The limiting hole 5 limits the reinforcing bar so that the reinforcing bar is accurately aligned with the through hole, which facilitates the rotation of the conveying rollers 9 to drive the reinforcing bar to move through the hole.

[0026] like Figures 1-2 As shown, in this embodiment, the electric telescopic rod 16 is screwed to the support plate 20 and the base plate 4. The telescopic end of the electric telescopic rod 16 is screwed to the support plate 7. The drive shaft 2 is rotatably connected to the support plate 20 and the support plate 7. The design of the electric telescopic rod 16 in conjunction with the support plate 20 and the support plate 7 facilitates stable support between the conveyor rollers 9.

[0027] like Figures 1-2As shown, in this embodiment, the slot 14 is formed on the support plate 15, the insert block 13 is screwed to the support plate 11, and the insert block 13 is slotted to the slot 14. The design of the slot 14 in conjunction with the insert block 13 facilitates the stability between the upper conveying roller 9 and the lower conveying roller 9.

[0028] like Figures 1-2 As shown, in this embodiment, the second support plate 15 is screwed to the bottom plate 4, the support rod 3 is screwed to both the bottom plate 4 and the top plate 1, and the hydraulic jack 10 is screwed to the first support plate 11. The support rod 3 fixes the top plate 1 and the bottom plate 4. The design of the hydraulic jack 10 facilitates the adjustment of the height of the second support plate 15, thereby adjusting the distance between the first support plate 11 and the second support plate 15, ensuring that the conveying roller 9 can convey steel bars of different widths.

[0029] like Figures 1-2 As shown, in this embodiment, the motor 12 is screwed to both the first support plate 11 and the second support plate 15. The motor 12 is keyed to the transmission shaft 2, and the transmission shaft 2 is screwed to the conveying roller 9. The motor 12 drives the transmission shaft 2 to rotate, thereby realizing the rotation of the conveying roller 9 on the transmission shaft 2. The two conveying rollers 9 rotate relative to each other, thus realizing the conveying of the reinforcing bars.

[0030] like Figures 1-2 As shown, in this embodiment, the anti-slip rubber pad 8 is bonded to the conveying roller 9, and the limiting plate 6 is screwed to the base plate 4. The design of the anti-slip rubber pad 8 is such that when the reinforcing bar is conveyed, the conveying roller 9 rolls and drives the reinforcing bar to move. At the same time, the reinforcing bar and the anti-slip rubber pad 8 on the transmission surface of the conveying roller 9 make direct contact, which can avoid rigid friction between the reinforcing bar and the device. With the compression pad 19 limiting the reinforcing bar, the integrity of the reinforcing bar surface before the reinforcing bar is pierced can be effectively guaranteed, avoiding the problem of repairing the reinforcing bar later.

[0031] like Figures 1-2 As shown, in this embodiment, the electric telescopic rod 18 is connected to the limiting hole 5 by screws, the telescopic end of the electric telescopic rod 18 is connected to the clamping plate 17 by screws, the compression pad 19 is bonded to the clamping plate 17, and the electric telescopic rod 18 drives the limiting plate 6 to move relative to each other, thereby realizing the limiting support of the reinforcing bar by the limiting plate 6. With the design of the compression pad 19, the stability of the reinforcing bar can be effectively guaranteed.

[0032] The specific implementation process of this embodiment is as follows: When using the device, it is necessary to place the device in an appropriate position and connect it to an external power source. One end of the rebar is passed through the limiting plate 6 on one side and between the two conveying rollers 9, and then through the other limiting plate 6. The electric telescopic rod 18 drives the clamping plate 17 to move relative to each other. With the design of the extrusion pad 19, the rebar can be limited, ensuring the stability of the rebar during piercing. Then, the hydraulic jack 10 presses down, and with the operation of the electric telescopic rod, the splicing between the support plate 11 and the support plate 2 15 is realized. The motor 12 drives the conveying roller 9 on the transmission shaft 2 to rotate, realizing the conveying action of the conveying roller 9 on the rebar. At the same time, with the design of the anti-slip rubber pad 8, the rigid friction caused by direct contact between the rebar and the conveying roller 9 can be effectively avoided. The limiting hole 5 is directly opposite the piercing plate, realizing the device to quickly pierce the rebar.
