Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and more specifically, to a steel bar processing device for building construction. Background Technology

[0002] Construction projects generally require a large amount of steel bars and concrete. Steel bars, as the skeleton of concrete, constitute reinforced concrete and have become the main material used in the widest range and in the largest quantity in building structures. Before pouring concrete, steel bars must be made into a skeleton of certain specifications and forms and incorporated into the formwork. When making the steel bar skeleton, a square frame is needed to limit the position of the steel bars. Since the amount of steel bar frames used in building construction is extremely large, it is difficult to complete by manual operation. Therefore, a steel bar bending machine is needed to bend the steel bars into the required square frame structure.

[0003] Chinese patent application number CN202321827493.7 discloses a rebar bending machine, including a worktable and further comprising: a conveying assembly, wherein two sets of conveying assemblies are symmetrically installed on the worktable, one set of which is slidably mounted on the worktable, and an adjusting assembly for adjusting the distance between the two sets of conveying assemblies is also provided on the worktable; and a bending assembly. This device can bend rebar at different positions and angles, has a wide range of applications, good performance, and high work efficiency.

[0004] However, as can be seen from the accompanying drawings in the instruction manual, existing rebar bending machines bend rebars through a bending mechanism. When it is necessary to bend the rebar into the required square frame, the rebar needs to be moved repeatedly to control the bending position in order to produce a finished square frame. This is inefficient, and the specifications and bending positions are prone to errors, affecting the performance. Therefore, a rebar processing device for building construction is proposed.

This facilitates the limiting and clamping of the steel bars and is easy to adapt to steel bars of different diameters. By controlling the movement of the bending pressure roller 13 through the driving bending mechanism, the steel bars can be bent into square brackets by the cooperation of the guide rollers 5, positioning rollers 4 and adjusting pressure roller 20, which is convenient for use.

[0029] A support column 6 is provided at the bottom of the guide roller 5. A lifting plate 7 is fixedly connected to the bottom of the support column 6. A support frame 8 is fixedly connected to the bottom of the worktable 1 at a position corresponding to the lifting plate 7. A stabilizing rod 9 is fixedly connected to the middle of the support frame 8. An electric push rod 10 is fixedly connected to the bottom of the support frame 8. Activating the electric push rod 10 controls the lifting plate 7 to move up and down. This can control the support column 6 to move the guide roller 5 out from the top of the worktable 1. The stability of the movement of the lifting plate 7 is improved by the stabilizing rod 9, which facilitates the bending of the steel bar on one side of the positioning roller 4.

The support column 6 passes through the middle of the worktable 1, and the top of the support column 6 is on the same horizontal plane as the top wall of the worktable 1. The support column 6 moves up and down, which drives the guide roller 5 to move up and down, so as to facilitate the control of the position of the guide roller 5.

[0033] As attached Figure 1 , 2As shown in Figures 3 and 5, the second limiting slider 14 is located at the bottom of the workbench 1. A threaded rod 15 is inserted into the middle of the second limiting slider 14. The two ends of the threaded rod 15 are respectively connected to the first support plate 16.

The first motor 17 is fixed to one side of the first support plate 16. By starting the first motor 17 to control the rotation of the threaded rod 15, the second limiting slider 14 can be controlled to drive the first limiting slider 12 to slide inside the limiting sliding hole 11, thereby controlling the movement of the bending pressure roller 13. Combined with the cooperation of the guide roller 5 and the adjusting pressure roller 20, or the cooperation of the positioning roller 4 and the adjusting pressure roller 20, the steel bar corresponding to the bending pressure roller 13 can be bent.

[0035] As attached Figure 1 , 2 As shown in Figures 3 and 6, the output end of the second motor 22 is connected to a rotating rod 23. One end of the rotating rod 23 is connected to a second support plate 25, which is fixed to the bottom of the workbench 1. A gear 24 is fixedly sleeved in the middle of the rotating rod 23. The gear 24 corresponds one-to-one with the rack 21, and the gear 24 and rack 21 mesh. Starting the second motor 22 controls the rotating rod 23 to drive the gear 24 to rotate, which can control the rack 21 to move horizontally. This controls the third limiting slider 19 to slide inside the limiting groove 18, thereby controlling the distance between the adjusting pressure roller 20 and the positioning roller 4, and simultaneously controlling the distance between the adjusting pressure roller 20 and the guide roller 5. This facilitates the use of different diameter steel bars for limiting and improves the performance.

[0036] It is worth noting that the guide roller 5, positioning roller 4, adjusting pressure roller 20 and bending pressure roller 13 are all rotatably connected to the rotating shaft in the middle of themselves, and the outer surfaces of the guide roller 5, positioning roller 4, adjusting pressure roller 20 and bending pressure roller 13 are all set with an arc-shaped structure.

Then, the second motor 22 is started to control the adjusting pressure roller 20 to move to one side of the positioning roller 4 and the guide roller 5 in sequence to clamp and limit the steel bar.

[0038] Then, the first motor 17 corresponding to the bottom of the bending roller 13 on the opposite side of the two guide rollers 5 is started to control the movement of the bending roller 13 in sequence. The two ends of the steel bar can be bent into ninety degrees by the cooperation of the guide rollers 5 and the bending roller 13, and then the bending roller 13 is controlled to reset.

[0039] Then, the electric push rod 10 is activated to control the guide roller 5 to move downward, so that the guide roller 5 moves out from the top of the worktable 1. Then, the first motor 17 corresponding to the bottom of the bending pressure roller 13 on the opposite side of the two positioning rollers 4 is activated to control the bending pressure roller 13 to move. In cooperation with the positioning roller 4 and the adjusting pressure roller 20, the middle part of the steel bar is bent, thereby bending it into a square frame for easy use.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
