Description

Technical Field

[0002] In order to evaluate the strength of steel bars, measure their performance, meet construction needs, and achieve more diverse building forms, steel bars need to be bent through bending devices during production and processing. To improve the bending efficiency of steel bars, most existing bending devices will install multiple steel bars on positioning blocks, and simultaneously bend multiple steel bars through the contact effect between the moving bending push block and the multiple steel bars. However, this bending method will also generate greater friction between the moving steel bars when bending the steel bars, which will obviously cause damage to the surface of the steel bars and has major defects. For this reason, we propose a steel bar bending device that can bend multiple steel bars at a time. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: a steel bar bending device that can bend multiple steel bars at one time, including a base 1 and multiple support plates 11, multiple support plates 11 are slidably installed on the upper end of the base 1, and lower clamping blocks 15 are fixedly installed on both sides of the front end of the support plate 11. The outer sides of the two lower clamping blocks 15 are provided with upper clamping blocks 16 that are rotatably connected to the front end of the support plate 11. A movable seat 2 is slidably installed in the middle of the front end of the support plate 11, and a bending push block 22 is installed at the front end of the movable seat 2. The front end of the support plate 11 is rotatably installed with a rotating seat 23, and a first rotating plate 25 is fixedly installed on the periphery of the rotating seat 23. A second rotating plate 26 rotatably connected to the outer end of the first rotating plate 25 is rotatably installed on the periphery of the movable seat 2. A limited position plug hole 24 is provided in the middle of the rotating seat 23, and a driving motor 12 is fixedly installed on the upper end of the base 1. A driving rod 17 that is plugged into the limit plug hole 24 is fixedly installed on the front end of the driving motor 12 through its output shaft.

[0022] Working principle: When in use, according to the number of steel bars to be bent in a single time, a corresponding number of support plates 11 can be installed on the upper end of the base 1, and the driving rod 17 and each limit socket 24 can be plugged into each other;

[0023] The steel bar is installed between the upper clamping block 16 and the lower clamping block 15, and the driving motor 12 is started. Through the plug connection between the driving rod 17 and the limiting socket 24, the driving motor 12 drives the rotating seat 23 to rotate through its output shaft, and through the rotating connection between the first rotating plate 25 and the second rotating plate 26 and the sliding connection between the movable seat 2 and the support plate 11, the bending push block 22 can be driven to move upward. Since the upper clamping block 16 is rotatably connected to the support plate 11, the moving bending push block 22 can completely bend the middle part of the steel bar, thereby achieving the effect of bending multiple steel bars at one time.

[0024] As a further description of the above technical solution: a limiting slide groove 13 is provided at the upper end of the base 1, and a limiting slider 14 is fixedly installed at the lower end of each support plate 11 and is slidably connected to the limiting slide groove 13; a limiting slide cavity 21 is provided in the middle of the front end of the support plate 11, and the movable seat 2 is slidably installed in the limiting slide cavity 21, and a limiting ring 28 is fixedly installed on the outer periphery of the front end of the movable seat 2, and a movable ring 27 is rotatably installed on the outer periphery of the limiting ring 28, and the second rotating plate 26 is fixedly installed on the outer end of the movable ring 27.

[0025] Specifically, through the sliding connection between the limiting slide groove 13 and the limiting slider 14, each support plate 11 can be installed and removed at the upper end of the base 1;

[0026] Through the sliding connection between the movable seat 2 and the limiting sliding cavity 21 and the rotational connection between the movable ring 27 and the limiting ring 28, when the first rotating plate 25 drives the second rotating plate 26 to move, the movable seat 2 can be driven to move up and down in the limiting sliding cavity 21.

[0027] As a further description of the above technical solution: a positioning hole 31 is provided in the movable seat 2, and a positioning rod 32 connected to the positioning hole 31 is fixedly installed at the rear end of the bending push block 22; a threaded curved groove 33 is provided on the outer periphery of the positioning rod 32, and a threaded ring 3 threadedly connected to the threaded curved groove 33 is rotatably installed at the rear end of the movable seat 2.

[0028] Specifically, when the model of the bending push block 22 needs to be adjusted according to the bending radius of the steel bar, the bending push block 22 can be installed on the front end of the movable seat 2 through the plug-in connection between the positioning rod 32 and the positioning socket 31. When the positioning rod 32 contacts the threaded ring 3, the threaded ring 3 is rotated, and the threaded connection between it and the threaded curved groove 33 can drive the positioning rod 32 to move and position it. When the bending push block 22 bends the steel bar, the bending push block 22 can be avoided from being offset.
