Description

Technical Field

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

[0002] There are many steel bars left in the steel bar processing shed at the construction site. In order to improve the utilization rate of steel bars and reduce economic losses, they are generally welded and spliced into horse stool bars, or bent into an "J" shaped horse stool bar. The existing steel bar bending equipment can generally bend both sides at the same time. However, the "J" shaped horse stool bar also needs to bend the bent parts at both ends to both sides respectively. Therefore, at this time, it is necessary to bend the bends to both sides one by one in sequence. The bottom bars of the "J" shaped horse stool bars bent in this way are likely to have different heights, and the bending angles on both sides are difficult to unify. For this reason, a steel bar bending equipment for use in construction is designed that can meet the bending requirements of L-shaped, U-shaped and "J" shaped steel bars, improve the efficiency and effect of steel bar bending, and reduce the limitations of steel bar bending.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0019] Example:

[0020] See also Figure 1-3 A steel bar bending equipment for construction, including an operating platform 1, the top of the operating platform 1 is symmetrically provided with two groups of upper bending reinforcement blocks 2, each of which has an upper bending groove 3 on the outside, and the lower parts of the two upper bending reinforcement blocks 2 are provided with lower bending reinforcement blocks 4, each of which has a vertical groove 5 adapted to the upper bending groove 3 on the outside, and the bottoms of the two lower bending reinforcement blocks 4 are provided with lower bending grooves 6 facing the front and rear sides, and also includes two upper bending rollers 7 adapted to the upper bending grooves 3 and two lower bending rollers 8 respectively adapted to the two lower bending grooves 6, and also includes a driving mechanism for driving the two It also includes a vertical bending drive mechanism for raising and lowering the upper bending groove 3, a horizontal bending drive mechanism for driving the lower bending roller 8 to move horizontally, and a unloading feeding mechanism for synchronously feeding the upper bending rib blocks 2 on both sides and the upper bending grooves 3 on both sides toward the middle. Furthermore, there is a sufficient bending distance between the bottom of the lower bending rib block 4 and the operating table 1, and it can be customized according to the actual bending length so as to perform a "J" shape bending, and support legs are provided at the bottom of the operating table 1, and the height of the support legs can also be adjusted accordingly.

[0021] Specifically, the upper bending reinforcement block 2 and the lower bending reinforcement block 4 on the same side are fixedly connected by a horizontal split movable frame 16, and the vertical bending drive mechanism includes a vertical bending drive cylinder 12 vertically fixedly installed on the top of the two upper bending reinforcement blocks 2 through a gantry frame 11, and a lifting frame 13 is fixedly installed on the bottom output shaft of the vertical bending drive cylinder 12. Slide sleeves 14 are horizontally slid on both sides of the lifting frame 13, and the two upper bending rollers 7 are rotatably installed on the bottom of the two slide sleeves 14 respectively. The bottom of the slide sleeve 14 is fixedly installed with a guide column 15 that slides with the upper bending reinforcement block 2 on the same side. The guide column 15 and the water pump 15 are fixedly installed. The flat split movable frame 16 is located on the same side of the upper bending rib block 2. Through the extension and retraction of the vertical bending drive cylinder 12, the two upper bending rollers 7 can be driven to move up and down through the lifting frame 13 and the sliding sleeve 14. Through the vertical cooperation of the guide column 15 and the upper bending rib block 2, it is convenient to maintain the upper bending roller 7 on one side of the upper bending groove 3 to ensure the horizontal spacing between them, thereby ensuring the vertical bending operation. Through the cooperation of the lifting frame 13, the sliding sleeve 14 and the guide column 15, it is convenient to drive the upper bending roller 7 to move synchronously when the two upper bending rib blocks 2 and the two lower bending rib blocks 4 move to both sides.

[0022] Specifically, the horizontal bending drive mechanism includes a horizontal bending drive cylinder 10 fixedly mounted on the operating table 1, and the output shaft of the horizontal bending drive cylinder 10 is fixedly mounted with a horizontal movable slide 9 that slides horizontally with the operating table 1, and the lower bending roller 8 is rotatably connected to the horizontal movable slide 9. Furthermore, a bending groove 20 is provided on the operating table 1 at a position symmetrical to the horizontal bending drive mechanism to ensure bending. When performing the last bend of the "J" shape, the horizontal bending drive cylinder 10 is started to extend the output shaft of the horizontal bending drive cylinder 10, and the lower bending roller 8 is pushed by the horizontal movable slide 9 to bend the steel bars stuck in the vertical groove 5 through the lower bending groove 6, thereby completing the entire "J" shape bend.

[0023] Specifically, the unloading feeding mechanism includes a bidirectional screw 17 laterally arranged below the two horizontally apart moving frames 16, and the bidirectional screw 17 is symmetrically connected to two sliders 19 that slide horizontally with the operating table 1. The two sliders 19 are respectively fixedly connected to the two horizontally apart moving frames 16, and also includes a pitch-adjusting motor 18 that drives the bidirectional screw 17 to rotate. Furthermore, the bidirectional screw 17 is rotatably connected to the operating table 1, and the pitch-adjusting motor 18 is fixedly installed on the operating table 1. Starting the pitch-adjusting motor 18 makes the output shaft of the pitch-adjusting motor 18 rotate clockwise or counterclockwise, which facilitates the bidirectional screw 17 to rotate clockwise or counterclockwise, thereby driving the two sliders 19 to move toward the middle or to both sides, and then driving the two horizontally apart moving frames 16 to move toward the middle or to both sides, so that the two upper bent reinforcement blocks 2 and the two upper bent grooves 3 move toward the middle, so that the "J"-shaped steel bars can be removed from the two upper bent reinforcement blocks 2 and the two upper bent grooves 3.

[0024] Specifically, two guide frames that can slide with the side walls of the upper bending rib block 2 are fixedly installed at the bottom of the sliding sleeve 14, and the upper bending roller 7 is rotatably connected to the two guide frames. Through the setting of the two guide frames, it is convenient to bend the upper bending roller 7 smoothly on one side of the upper bending groove 3, thereby improving the bending effect.
