DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 and Figure 4 As shown, the utility model provides a technical solution: a steel bar bending mechanism for construction, comprising a workbench 1 and a steel bar main body 12, the upper top of the workbench 1 is fixedly connected with an auxiliary frame 11, the middle part of the outer wall of the auxiliary frame 11 is fixedly connected with a slot frame 3, the steel bar main body 12 is placed inside the slot frame 3, the upper top of the workbench 1 is located on one side of the auxiliary frame 11 and is provided with a chuck structure for bending the steel bar main body 12, and the outer wall of the auxiliary frame 11 is provided with a restraining structure for restricting the steel bar main body 12.

[0022] By adopting the above scheme, the auxiliary frame 11 and the slot frame 3 are arranged on the workbench 1, so as to ensure that the steel bar body 12 maintains a stable position and posture during the bending process. The internal design of the slot frame 3 is specially designed for placing the steel bar body 12, which effectively prevents the steel bar from moving or shaking before bending, and improves the processing accuracy. The chuck structure can adjust the bending angle and strength as needed to meet different construction requirements, improve work efficiency and product quality, and the restraining structure arranged on the outer wall of the auxiliary frame 11 further enhances the stability of the steel bar body 12 during the bending process, and prevents safety hazards caused by sudden sliding or popping out of the steel bar.

[0023] like Figure 1 and Figure 2 As shown, the chuck structure includes a first chuck 2 fixedly connected to the top of the workbench 1, a telescopic outer frame 22 is provided on the top of the workbench 1, a telescopic inner frame 23 is slidably connected to the inside of the telescopic outer frame 22, and a second chuck 21 is rotatably connected to the end of the telescopic inner frame 23, an outer wall of the telescopic inner frame 23 is fixedly connected to a rotating frame 24, an inner wall of the rotating frame 24 is fixedly connected to a plurality of supporting frames 241, and an outer wall of the rotating frame 24 is fixedly connected to a push-pull handle 242, a limit rod 221 for limiting the sliding of the telescopic inner frame 23 is threadedly connected to the upper top of the telescopic outer frame 22, and a fixing rod 25 is fixedly connected to the lower bottom end of the telescopic outer frame 22, and an arc-shaped slide groove 13 matching the fixing rod 25 is provided on the upper top of the workbench 1.

[0024] By adopting the above scheme, through the sliding connection design of the telescopic outer frame 22 and the telescopic inner frame 23, the distance between the second chuck 21 and the first chuck 2 can be flexibly adjusted to adapt to the steel bar body 12 of different lengths and bending requirements. The first chuck 2 and the second chuck 21 work together to effectively clamp the steel bar body 12 to ensure the stability of the steel bar during the bending process. The limit rod 221 is threadedly connected to the upper top of the telescopic outer frame 22 to limit the sliding range of the telescopic inner frame 23, thereby ensuring the accuracy of the telescopic inner frame 23 during the adjustment process and preventing excessive sliding or accidental movement. The matching design of the fixing rod 25 and the arc-shaped slide groove 13 provides a stable support and guiding effect for the telescopic outer frame 22, which not only enhances the stability of the entire chuck structure, but also helps to maintain the linearity and accuracy of the telescopic outer frame 22 during movement.

[0025] like Figure 3 and Figure 4As shown, the binding structure includes a servo motor 4 fixedly connected to the outer wall of the auxiliary frame 11, the output end of the servo motor 4 is fixedly connected to a driving rod 41, the outer wall of the driving rod 41 is symmetrically fixedly connected to a winding wheel 42, the outer wall of the winding wheel 42 is wrapped with a steel cable 43, the outer wall of the auxiliary frame 11 is symmetrically fixedly connected to a support seat 47, the binding structure also includes a second rotating rod 45 rotatably connected to the inner wall of the two support seats 47, the outer wall of the second rotating rod 45 is fixedly connected to a take-up wheel 46 arranged opposite to the winding wheel 42, the steel cable 43 passes through the auxiliary frame 11 and is wrapped around the outer wall of the take-up wheel 46, and a ring for binding the steel bar body 12 is formed on the outer wall of the auxiliary frame 11, the outer walls of the driving rod 41 and the second rotating rod 45 are both fixedly connected to gears 44, and the two gears 44 are meshed with each other.

[0026] By adopting the above scheme, the combination of the twisting wheel 42 and the take-up wheel 46 enables the steel cable 43 to firmly wrap around and bind the steel bar body 12. At the same time, the formation of the ring further enhances the binding effect, ensuring the stability and safety of the steel bar during the bending process. The driving rod 41 and the second rotating rod 45 realize synchronous rotation through the mutual engagement of the gear 44, ensuring the coordination and consistency of the twisting wheel 42 and the take-up wheel 46 during the rotation process. The design of the binding structure allows adjustment according to the diameter and length of the steel bar body 12. By adjusting the number of winding turns and the tightness of the steel cable 43, it can adapt to steel bar materials of different specifications and requirements, thereby improving the flexibility and adaptability of the binding structure.

[0027] like Figure 3 and Figure 4 As shown, the outer wall of the auxiliary frame 11 is symmetrically fixedly connected with two groups of first fixed brackets 31, the inner wall of the first fixed bracket 31 is fixedly connected with a first rotating rod 32, the outer wall of the first rotating rod 32 is symmetrically rotatably connected with a movable wheel 33, the steel cable 43 is slidably connected to the outer wall of the movable wheel 33, and the ring is located on the outside of the slot frame 3.

[0028] By adopting the above scheme, the design of the movable wheel 33 enables the steel cable rope 43 to slide smoothly on its outer wall, reducing the friction and resistance of the steel cable rope 43 during movement. The first rotating rod 32 and the movable wheel 33 thereon provide a stable guiding effect for the steel cable rope 43, ensuring the path accuracy and consistency of the steel cable rope 43 during winding and loosening. Through the sliding connection of the movable wheel 33, the steel cable rope 43 will not directly generate hard friction with the fixed component when moving, thereby avoiding excessive wear and damage of the steel cable rope 43.

[0029] Working principle: When in use, first hold the push-pull handle 242 to drive the rotating frame 24 to move, and the rotating frame 24 will drive the telescopic inner frame 23 and the telescopic outer frame 22 to move, and make an arc movement with the help of the fixed rod 25 and the arc-shaped slide groove 13. At this time, the steel bar body 12 is inserted from the inside of the slot frame 3 and passes out from the gap between the first chuck 2 and the second chuck 21. The steel bar body 12 needs to be tightly attached to the inside of the first chuck 2. In order to ensure stability during the bending process, the outside of the steel bar body 12 needs to be limited. At this time, the staff can use the servo motor 4 to drive the driving rod 41, the stranding wheel 42 and the gear 44 to rotate. At this time, the relative movement of the two gears 44 can drive the second The rotating rod 45 and the take-up wheel 46 rotate. Since the two ends of the steel cable 43 are respectively wound around the take-up wheel 46 and the twisting wheel 42, when the two move relative to each other, the steel cable 43 can be tightened. The steel bar body 12 is located in the gap between the slot frame 3 and the steel cable 43. At this time, the steel bar body 12 can be bound. When the binding needs to be released, the gear 44 is moved in the opposite direction to relax the steel cable 43. Then, the rotating frame 24 and the second chuck 21 are rotated forcefully so that the second chuck 21 applies a corresponding thrust to the steel bar body 12. At this time, the steel bar body 12 can be bent under the thrust and at the limit of the first chuck 2, and the user can control the bending angle according to needs.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
