Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar bending devices, and particularly relates to a steel bar bending device for building construction. Background Technique

[0002] A steel bar bender, one of the steel bar processing machines, has a working mechanism that is a horizontal working disc rotating on a vertical axis. Place the steel bar at the position of the dotted line in the figure. The supporting pin shaft is fixed on the machine tool, and the central pin shaft and the bending pin shaft are installed on the working disc. When the disc rotates, the steel bar is bent.

[0003] According to a steel bar bending device for building construction disclosed in patent number CN202323126732.9, which includes a base, a support plate is fixedly connected to the upper end of the base, a bending plate is rotatably connected to one end of the support plate, and a plurality of steel bar grooves are opened on the upper ends of the support plate and the bending plate.

[0004] In the actual use process of the above scheme, there are still certain technical defects. Since the bending plate bends the steel bar by flipping upwards, when it is necessary to bend the steel bar into a loop shape, after the first bending, when the second bending is completed, it is difficult to ensure that the bent part can maintain a vertical state, and it is easily deflected under the action of gravity, resulting in a situation where the interfaces of the steel bar bent into a loop do not connect, which is not conducive to use. Moreover, due to the use of a hydraulic rod to push, it is difficult for the bending plate to perform a U-shaped bending on the steel bar. Therefore, we propose a steel bar bending device for building construction. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a steel bar bending device for building construction to solve the existing problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A steel bar bending device for building construction, including a processing table, a turntable, and a bending roller. Notches are opened on both sides at one end of the processing table. A turntable is movably connected inside the notches through a connecting shaft. Both ends of the connecting shaft are movably connected to the inner side walls of both sides of the notches through bearings. One side of the turntable protrudes from the notch and extends to the outside. A connecting block is fixedly welded on the outer periphery of one side of the turntable. A bending roller is movably connected between the two connecting blocks through a rotating shaft. Synchronous motors are fixedly installed on both sides of the processing table at the end where the turntable is located. The end of the output shaft of the synchronous motor is fixedly connected to the connecting shaft.

[0007] Preferably, a welding frame is provided at one end of the top of the processing table away from the turntable. The welding frame is fixedly installed on the top of the processing table by welding. The welding frame is of a U-shaped structure. A pressing plate is arranged inside the welding frame. An electric push rod is fixedly embedded at the top of the welding frame. The end of the electric push rod passes through the welding frame and is fixedly connected to the center position of the top of the pressing plate.

[0008] Preferably, an arc-shaped contact block is provided at the end of the processing table where the turntable is located. The arc-shaped contact block is fixedly installed at the end of one end of the processing table by welding.

[0009] Preferably, a plurality of second arc-shaped grooves are formed on the top surface of the processing table. The second arc-shaped grooves penetrate through both ends of the processing table. A plurality of first arc-shaped grooves are provided at the bottom of the pressing plate. The positions where the first arc-shaped grooves are formed correspond to the second arc-shaped grooves.

[0010] Preferably, sliding sleeves are fixedly embedded at both ends of the top of the welding frame. Guide rods are fixedly welded at both ends of the top of the pressing plate. The guide rods pass through the sliding sleeves and are slidably connected to them.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing two turntables driven by a synchronous motor at one end of the processing table and arranging a bending roller between them, the force generated by the turntable driving the bending roller to rotate downward around the center of the turntable is used to bend the steel bar downward. When the steel bar is bent into a U shape, under the action of the self-gravity of the bent part, it can be perpendicular downward, effectively avoiding the situation that when performing the secondary bending, the bent part shifts, resulting in a poor U-shaped bending effect of the steel bar and dislocation.

[0015] 2. By using the turntable to drive the bending roller to bend the steel bar, the bending angle of the steel bar can be controlled by the rotation angle of the turntable during processing. Moreover, when the bending roller rotates to the bottom of the processing table following the turntable, the U-shaped processing of the steel bar can be realized, greatly improving the versatility of the equipment.

Specific implementation mode

[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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3 , the present utility model provides a technical solution for a steel bar bending device for building construction: including a processing table 1, a turntable 12 and a bending roller 14. Notches 11 are opened on both sides at one end of the processing table 1. The inside of the notch 11 is movably connected to the turntable 12 through a connecting shaft. The two ends of the connecting shaft are respectively movably connected to the inner side walls on both sides of the notch 11 through bearings. One side of the turntable 12 protrudes from the notch 11 and extends to the outside. A connecting block 13 is fixedly welded to the outer periphery of one side of the turntable 12. A bending roller 14 is movably connected between the two connecting blocks 13 through a rotating shaft. Synchronous motors 15 are fixedly installed on both sides of the end of the processing table 1 where the turntable 12 is provided. The end of the output shaft of the synchronous motor 15 is fixedly connected to the connecting shaft.

[0022] Specifically, a welding frame 4 is provided at the end of the top of the processing table 1 away from the turntable 12. The welding frame 4 is fixedly installed on the top of the processing table 1 by welding. The welding frame 4 is of a U-shaped structure. A pressing plate 6 is provided inside the welding frame 4. An electric push rod 5 is fixedly embedded in the top of the welding frame 4. The end of the electric push rod 5 passes through the welding frame 4 and is fixedly connected to the center position of the top of the pressing plate 6.

[0023] Specifically, an arc contact block 16 is provided at the end of the end of the processing table 1 where the turntable 12 is provided. The arc contact block 16 is fixedly installed at the end of one end of the processing table 1 by welding.

[0024] Specifically, a plurality of second arc grooves 8 are opened on the top surface of the processing table 1. The second arc grooves 8 penetrate through both ends of the processing table 1. A plurality of first arc grooves 7 are provided at the bottom of the pressing plate 6. The positions where the first arc grooves 7 are opened correspond to the second arc grooves 8.

[0025] Specifically, sliding sleeves 9 are fixedly embedded at both ends of the top of the welding frame 4, and guide rods 10 are fixedly welded at both ends of the top of the pressing plate 6. The guide rods 10 pass through the sliding sleeves 9 and are slidably connected thereto.

[0026] Specifically, a support frame 2 is provided at the bottom of the processing table 1, and the support frame 2 is fixedly installed at the bottom of the processing table 1 by welding.

[0027] Specifically, a control panel 3 is provided on one side of the outside of the processing table 1, and the control panel 3 is fixedly installed on one side of the outside of the processing table 1 by mounting screws.

[0028] In this embodiment, during use, multiple steel bars are sequentially placed into the inner part of the second arc-shaped groove 8, and then by operating the control panel 3, the electric push rod 5 is driven to push the pressing plate 6 downwards, so that the first arc-shaped groove 7 coincides with the second arc-shaped groove 8, thereby fixing the steel bar in the cylindrical groove formed by the first arc-shaped groove 7 and the second arc-shaped groove 8, and extending the end part to be bent out of the second arc-shaped groove 8. Then, the control panel 3 is operated to drive the synchronous motors 15, so that the two synchronous motors 15 rotate synchronously, thereby driving the turntable 12 to rotate by means of the connecting shaft, so that the connecting block 13 outside the turntable 12 drives the bending roller 14 to bend the end part of the steel bar, and the bending part of the steel bar is contacted by the arc-shaped contact block 16 to ensure the stability of the bending effect. When the steel bar needs to be bent into a loop, after bending, the steel bar can be directly pushed to extend towards the bending end again. Due to the gravity of the steel bar, the bent part can be vertically downward, and then it is compacted by the pressing plate 6, and the turntable 12 is driven by the two synchronous motors 15 to drive the bending roller 14 to perform secondary bending processing on it. Such a design enables the bent part to be vertically downward under the action of its own gravity when the steel bar is bent into a loop, effectively avoiding the situation that the bent part is offset during secondary bending, resulting in a poor loop bending effect of the steel bar and misalignment.
