Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, in particular to a steel bar bending tool. Background Art

[0002] In the process of constructing the column reinforcement cage, due to the unique annular design of the circular stirrups, the bending of the circular stirrups requires higher precision than the processing of straight steel bars, so the production of circular stirrups is particularly critical. Under normal circumstances, in order to form a precise closed steel bar skeleton, it is a common practice to rely mainly on steel bar bending machines to gradually bend straight steel bars into circles.

[0003] However, the structure of the steel bar bending machine is complex, the processing steps are many, and the maintenance cost is relatively high, which places higher requirements on the budget of the construction project and the skills of the operators. More importantly, the steel bar bending machine usually occupies a large area, which limits its flexible deployment for construction sites with limited space, especially in city centers or compact construction sites. As a result, the steel bar bending machine cannot be well applied and promoted.

[0004] In view of the above difficulties, it is particularly important to explore a more efficient, economical and adaptable round stirrup manufacturing equipment. Utility Model Content

[0005] In order to overcome the above technical defects, the utility model provides a steel bar bending tool to solve the problems involved in the background technology.

[0006] The utility model provides a steel bar bending tool, comprising:

[0007] A rotating device, a first disk body transmission-connected to the rotating device, a plurality of circularly distributed bending parts welded on the first disk body, a snap-fit ​​part arranged outside the circular contour where the bending parts are located, and a stopper arranged outside the first disk body.

[0008] Preferably or optionally, the first disk body is provided with three threaded holes distributed in a regular triangle.

[0009] Preferably or optionally, the distance between the buckle portion and the bending portion is greater than the diameter of the bent steel bar.

[0010] Preferably or optionally, the stopper comprises a main body, a limiting portion arranged on the upper part of the main body, and a rotating sleeve sleeved on the outside of the main body.

[0011] Preferably or optionally, the cross-sectional shape of the stopper and limiter assembly is T-shaped.

[0012] Preferably or optionally, it further comprises: a second disk body which is equal in size to the first disk body, and a plurality of inserting tube portions which are arranged on the second disk body and penetrate through the second disk body and correspond to the bending portions.

[0013] Preferably or optionally, the number of the insert portions is at least greater than two and is less than or equal to the number of the bending portions.

[0014] Preferably or optionally, part or all of the bent portion is higher than the insert portion.

[0015] Preferably or optionally, a latch hole is provided on the bent portion, suitable for installing a latch.

[0016] The utility model relates to a steel bar bending tool, which has the following beneficial effects compared with the prior art:

[0017] On the one hand, the utility model drives the rotation of the first disk body through the rotating device, and under the blocking of the gear member and the action of the circularly distributed bending part, the steel bar is bent into a circle. The structure of the entire tooling is simple, easy to manufacture and operate, and effectively solves the problems of low efficiency and large space occupation in traditional steel bar bending machines. It is particularly suitable for scenarios where space is limited or high-precision processing is required.

[0018] On the other hand, the utility model not only enhances the structural stability of the steel bar bending tooling by adding the second disk body and the inserting tube part, effectively controls the potential safety hazards during the operation process, but also provides a more efficient and safe bending equipment for steel bar processing by improving the flexibility and adaptability of the operation.

DETAILED DESCRIPTION

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] See attached Figures 1 to 3 A steel bar bending tool comprises: a rotating device, a first disk body 100, a bending portion 200, a buckle portion 300 and a stopper 400.

[0025] The rotating device is a servo motor, which ensures that the power output is stable and controllable, and improves the accuracy and efficiency of the processing. The first disk body 100 is the main body base of the tooling, which is connected to the rotating device in a transmission manner. The first disk body 100 is cut from a steel plate with a thickness of 20mm and a diameter of 1000mm, providing a stable working platform. The bending part 200 is a curved body with a diameter of 40mm and a height of 50mm. It is welded on the first disk body 100 in a circular distribution with a circle as the axis, and directly participates in the bending forming process of the steel bar. Its size and layout design ensure the roundness and size of the bent steel bar. The buckle part 300 is made of a steel column with a diameter of 20mm and a height of 30mm, and is arranged outside the circular contour of the bending part 200. The spacing between the buckle part 300 and the bending part 200 is 6-10mm, which is greater than or equal to the diameter of the curved steel bar, ensuring that the steel bar can move smoothly even during the bending process, and will not be deformed or damaged due to over-tightening. The stopper 400 is arranged outside the first disk body 100 and is welded on the workbench to limit the forward path of the straight steel bar, prevent the steel bar from deviating from the predetermined trajectory during the bending process, and ensure the accuracy of the processing.

[0026] In a further embodiment, three threaded holes 500 distributed in an equilateral triangle are provided on the first plate 100. The threaded holes 500 are M20 threaded holes 500, which are used for hoisting and / or fixing the servo motor, facilitating the installation, commissioning and daily maintenance of the tooling.

[0027] During high-intensity bending operations, if the steel bar is accidentally ejected, it may cause harm to the operator or damage surrounding equipment. Therefore, the applicant has designed from two aspects to avoid such safety hazards and ensure the safety of the operation.

[0028] On the one hand, see Appendix Figure 2The stopper 400 includes a main body 410, a limiting portion 420 disposed on the upper part of the main body 410, and a rotating sleeve 430 sleeved on the outside of the main body 410; the stopper 400 and the limiting portion 420 assembly is an integrated structure, and its cross-sectional shape is T-shaped. The T-shaped cross-section has good bending resistance and guiding properties, so that the stopper 400 is more stable when guiding the steel bar to bend along a predetermined path, and is not easy to shake or twist. The limiting portion 420 can prevent the straight steel bar from popping out before entering the bending process, reduce safety hazards, and ensure operational safety. The rotating sleeve 430 can ensure that the path of the straight steel bar is unobstructed before entering the bending process, reduce resistance and potential jamming, and improve work efficiency.

[0029] On the other hand, see Appendix Figure 3 , the tooling also includes: a second disk body 600 of the same size as the first disk body 100, and a plurality of inserting tube portions 700 arranged on the second disk body 600 and penetrating the second disk body 600 and corresponding to the bending portion 200. Part or all of the bending portion 200 is higher than the inserting tube portion 700, and a latch hole 210 is arranged on the bending portion 200 for installing a latch. The number of the inserting tube portions 700 is the same as the number of the bending portion 200, which means that the number of the inserting tube portions 700 is at least greater than two and less than or equal to the number of the bending portion 200. The first disk body 100 and the second disk body 600 are interlocked by the cooperation of the inserting tube portion 700 and the partial bending portion 200 and fixed by the latch, so as to prevent the steel bar from popping out due to uneven force during the bending process, reduce safety hazards, and ensure operation safety.

[0030] In order to facilitate understanding of the technical solution of the steel bar bending tool, a brief description is made of its working principle: the first disk body 100 is hoisted to a predetermined position through the threaded hole 500 and fixed on the servo motor to realize the connection between the first disk body 100 and the rotating device; then the second disk body 600 is hoisted onto the first disk body 100, and the first disk body 100 and the second disk body 600 are fixed by the cooperation of the inserting tube part 700 and the partial bending part 200, so as to realize the interlocking of the first disk body 100 and the second disk body 600; then the forward and reverse rotation of the bending tool is controlled by the switch of the servo motor, and the straightened and cut steel bars are fixed on the buckle part 300, and the rotation of the servo motor is controlled to make the steel bars bent under the blocking of the stopper 400 and the circularly distributed bending part 200.

[0031] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
