Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building steel bar bending device. Background Art

[0002] Steel bars refer to steel materials used in reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular and sometimes square with rounded corners. Steel bars are mainly used in various large-scale, heavy-duty, light-thin-walled and high-rise building structures, and are divided into plain round bars, ribbed bars and twisted bars.

[0003] During the building construction process, a large number of steel bars with different shapes are required. Therefore, a bending device needs to be used to bend the steel bars. When bending the steel bars, the middle position of the steel bar is extruded and bent by a pressing block. However, the lengths of the steel bars are different, and it is impossible to ensure that the pressing block contacts the middle position of the steel bar. When the middle position of the pressing block and the steel bar is offset, the bending effect of the steel bar is reduced. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the lengths of the existing steel bars are different and it is impossible to ensure that the pressing block contacts the middle position of the steel bar, and to provide a building steel bar bending device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Design a building steel bar bending device, including a chassis. A hydraulic cylinder is fixedly connected to the upper end of the chassis. An extrusion block is fixedly connected to the telescopic end of the hydraulic cylinder. A feeding mechanism for guiding the steel bar is connected to the chassis. Limiting mechanisms are connected to both sides of the upper end of the chassis. The extrusion block is located between the two limiting mechanisms. A supporting mechanism is fixedly connected to the upper end of the chassis;

[0007] The feeding mechanism includes a first mounting block. The first mounting block is fixedly connected to the chassis. A bidirectional screw is rotatably connected to the first mounting block. An activity hole is formed in the chassis. Two symmetrically arranged support frames are slidably connected to the activity hole. A first threaded hole is formed in each support frame. The first threaded hole is matched with the bidirectional screw.

[0008] Preferably, the extrusion block is an arc-shaped block.

[0009] Preferably, a turntable is fixedly connected to one end of the bidirectional screw.

[0010] Preferably, the limiting mechanism includes a rotating shaft. The rotating shaft is rotatably connected to the upper end of the chassis. A rotating wheel is fixedly connected to the upper end of the rotating shaft.

[0011] Preferably, the support mechanism includes a second mounting block fixedly connected to the upper end of the chassis. A second threaded hole is provided in the second mounting block, and a threaded rod is connected to the second threaded hole. A limiting block is slidably connected to the upper end of the chassis. One end of the threaded rod is rotatably connected to the limiting block, and an arc-shaped groove is provided in the limiting block.

[0012] Preferably, notch openings are provided on both sides of the arc-shaped groove.

[0013] A building steel bar bending device proposed by the present utility model has the beneficial effects that:

[0014] By driving the bidirectional screw rod to rotate through the turntable, after the bidirectional screw rod rotates, the two support frames move towards each other. After the two support frames move towards each other, the distance between the two support frames is shortened. When the distance value between the two support frames is the length of the bent steel bar, stop rotating the turntable. By adjusting the distance between the two support frames, the steel bars of different lengths are limited and guided, so that the extrusion block is located in the middle position of the steel bar, facilitating the bending process of steel bars of different lengths.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Example 1: Refer to Figures 1 - 3 , a building steel bar bending device, including a chassis 1, a hydraulic cylinder 2 is fixedly connected to the upper end of the chassis 1, an extrusion block 4 is fixedly connected to the telescopic end of the hydraulic cylinder 2, the extrusion block 4 is an arc-shaped block, a feeding mechanism 3 for guiding the steel bar is connected to the chassis 1, both sides of the upper end of the chassis 1 are connected with a limiting mechanism 5, the extrusion block 4 is located between the two limiting mechanisms 5, and a supporting mechanism 6 is fixedly connected to the upper end of the chassis 1;

[0022] The feeding mechanism 3 includes a first mounting block 31, the first mounting block 31 is fixedly connected to the chassis 1, a bidirectional screw 32 is rotatably connected to the first mounting block 31, a moving hole 33 is opened on the chassis 1, two symmetrically arranged support frames 34 are slidably connected to the moving hole 33, a first threaded hole is opened on each support frame 34, the first threaded hole is matched with the bidirectional screw 32, and one end of the bidirectional screw 32 is fixedly connected with a turntable 35.

[0023] Working process:

[0024] According to the length of the steel bar, the turntable 35 drives the bidirectional screw 32 to rotate. After the bidirectional screw 32 rotates, the two support frames 34 move towards each other. After the two support frames 34 move towards each other, the distance between the two support frames 34 shortens. When the distance value between the two support frames 34 is the length of the bent steel bar, stop rotating the turntable 35;

[0025] Place the steel bar between the two support frames 34, and the two support frames 34 respectively support the two ends of the steel bar. After the hydraulic cylinder 2 is started, it drives the extrusion block 4 to extend a set distance. During the extension of the extrusion block 4, the extrusion block 4 pushes the steel bar to contact the two limiting mechanisms 5, and the two limiting mechanisms 5 limit the two ends of the steel bar. The position where the steel bar contacts the extrusion block 4 is bent. After the bent part of the steel bar contacts the supporting mechanism 6, the hydraulic cylinder 2 stops pushing. By adjusting the distance between the two support frames 34, the steel bars of different lengths are limited and guided, so that the extrusion block 4 is in the middle position of the steel bar, which is convenient for bending processing of steel bars of different lengths.

[0026] Example 2: In Example 1, when the steel bar is limited, the friction between the steel bar and the limiting mechanism 5 is relatively large. Refer to Figure 4 , as another preferred embodiment of the present invention, the difference from Example 1 is that the limiting mechanism 5 includes a rotating shaft 51, the rotating shaft 51 is rotatably connected to the upper end of the chassis 1, a rotating wheel 52 is fixedly connected to the upper end of the rotating shaft 51, the steel bar falls on the rotating wheel 52, when the steel bar is bent, it squeezes the rotating wheel 52, the rotating wheel 52 rotates around the rotating shaft 51, and the rotating wheel 52 is in rolling contact with the steel bar, reducing the friction suffered by the steel bar when it is bent.

[0027] Embodiment 3: In Embodiment 1, when bending the steel bar by the extrusion block 4, the bending angle of the steel bar cannot be controlled. Refer to Figure 4 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the support mechanism 6 includes a second mounting block 61. The second mounting block 61 is fixedly connected to the upper end of the chassis 1. A second threaded hole is provided on the second mounting block 61. A threaded rod 62 is connected to the second threaded hole. A limiting block 63 is slidably connected to the upper end of the chassis 1. One end of the threaded rod 62 is rotatably connected to the limiting block 63. An arc-shaped groove 64 is provided on the limiting block 63. Notch openings 65 are provided on both sides of the arc-shaped groove 64. After the threaded rod 62 rotates, it drives the limiting block 63 to move under the limitation of the second threaded hole. After the limiting block 63 moves, the distance between the arc-shaped groove 64 and the limiting mechanism 5 is changed, thereby changing the contact position between the steel bar and the arc-shaped groove 64, and further changing the bending angle of the steel bar. The setting of the notch openings 65 prevents the steel bar from contacting the inner wall of the arc-shaped groove 64.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
