Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically a steel bar bending device. Background Technology

[0002] Construction is a general term for buildings and structures. Reinforcing steel refers to steel used in reinforced concrete and prestressed reinforced concrete, with a circular or square cross-section. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. In building construction, reinforcing steel bars are mixed with concrete to increase the overall strength of the building. During the use of reinforcing steel bars, they need to be bent according to the specific conditions of the construction site, thus requiring a steel bar bending device for processing.

[0003] The current steel bar bending machines have relatively fixed installation positions for the limiting structure and movement trajectories for the bending structure. They can only perform simple bending operations. When Z-shaped or other bending structures are required, the length of the steel bar bending section needs to be measured and multiple operations need to be performed, which is inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a steel bar bending device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment of the utility model, a steel bar bending device includes a housing 1, a workbench 2, and a force-applying structure 3. The housing 1 includes a box body 101, and a mounting platform 103 is provided on the upper side of the box body 101. The workbench 2 includes a platform body 201, which is mutually mounted with the mounting platform 103. A rotating platform 202 is rotatably mounted on the upper surface of the platform body 201. A column slot 203 is provided on the upper surface of the rotating platform 202. A column slide rail 206 is provided at the edge of the upper surface of the platform body 201. The force-applying structure 3 includes a first force-applying column 301 and a second force-applying column 302.

[0026] Specifically, according to the required rebar bending scheme, the first force-applying column 301 is installed in the column slot 203 at a suitable position on the rotating platform 202. Then, the second force-applying column 302 is slid to a suitable position on the column slide rail 206. By rotating the rotating platform 202, the second force-applying column 302 is used for limiting the position, and the first force-applying column 301 is used for applying force to achieve the bending effect of the rebar. For example, taking the front side of the box door 104 as the front of the overall structure, the rebar is placed in a horizontal position on both sides on the column slide rail 206 and the upper surface of the rotating platform 202. The rebar abuts against the front surface of the abutment plate 306 and against the rear surface of the first force-applying column 301 at the center of the rotating platform 202. Another first force-applying column 301 is installed in the column slot 203 at the rear edge of the rotating platform 202, located on the rear surface of the rebar. After rotating the rotating platform 202, the rebar is bent by the abutment plate 306. 06. One end of the reinforcing bar is limited. The No. 1 force-applying column 301 at the center of the rotating platform 202 serves as the bending fulcrum. When the No. 1 force-applying column 301 rotates, it pushes the other end of the reinforcing bar to deflect, thus achieving the bending operation. A No. 2 force-applying column 302 and abutment plate 306 can be installed on the upper side of the column slide rail on the other side to limit the deflection of the other end of the reinforcing bar. This allows the No. 1 force-applying column 301 at the rear of the rotating platform 202 to serve as the second turning fulcrum, bending the reinforcing bar into a Z-shaped structure in one go. Multiple sets of column slots 203 are provided, each set arranged in a ring-shaped equiangular array on the upper surface of the rotating platform 202. The radius of each set of column slots 203 is different, so the middle part of the Z-shaped bending structure can be directly bent to a fixed length, thus saving the measurement work of the bending section. The installation scheme of the No. 1 force-applying column 301 and the No. 2 force-applying column 302 can be freely matched according to the bending requirements, making it convenient to use.

[0027] Example 1

[0028] like Figures 1-2 As shown, in this embodiment, fixing feet 102 are fixedly installed at the four corners of the bottom side of the box 101, and a box door 104 is hinged to the front opening of the box 101; a motor mounting base 105 is fixedly installed on the bottom of the box 101, a drive motor 106 is fixedly installed on the upper side of the motor mounting base 105, and a reduction gearbox 107 is fixedly installed on the upper side of the drive motor 106.

[0029] In this embodiment, the drive motor 106 and other motorized equipment are placed inside the housing 101 for protection. Inspection and maintenance can be carried out through the housing door 104. The drive motor 106 is driven by the reduction gearbox 107 to reduce speed and amplify torque to drive the rotating seat 204 and the rotating table 202 to rotate, bending the steel bars. The output end of the reduction gearbox 107 is engaged with the rotating seat 204.

[0030] like Figures 1-3As shown, in this embodiment, a rotating seat 204 is fixedly installed at the bottom of the rotating table 202. The rotating seat 204 is rotatably embedded inside the table body 201. The lower edge of the rotating seat 204 has auxiliary balls 205 arranged in a ring at equal angles and rolling against it. The auxiliary balls 205 are embedded inside the table body 201.

[0031] In practice, the rotary table 202 and the rotating seat 204 are rotatably installed in the middle of the table body 201, while the table body 201 is clamped on the upper side of the clamping table 103 and fixed relative to each other by bolts, so that the entire worktable 2 has the ability to be disassembled and replaced. When the existing worktable 2 cannot meet the bending requirements, the entire worktable 2 can be directly replaced.

[0032] Example 2

[0033] Based on Embodiment 1, in order to supplement the specific adjustment and arrangement of each No. 1 force-applying column 301 and No. 2 force-applying column 302 on the upper surface of the platform 201, which was not mentioned in Embodiment 1, this invention further provides an explanation of the specific adjustment and arrangement of each force-applying column 301 and No. 2 force-applying column 302 on the upper surface of the platform 201.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a fastening bolt 303 is inserted inside the second force-applying column 302, and all fastening nuts 304 are fixedly installed at the lower end of the fastening bolt 303. A limit nut 305 is screwed onto the upper end of the fastening bolt 303. A backing plate 306 is fixedly installed on one side of the second force-applying column 302, and a reinforcing bracket 307 is fixedly installed on the rear surface of the backing plate 306. A backing block 308 is fixedly installed at the base of the bottom side of the reinforcing bracket 307. The lower end of the first force-applying column 301 is screwed into the column slot 203, and the lower end of the second force-applying column 302 is secured inside the column slide rail 206 by the limit nut 305.

[0035] In specific implementation, the first force-applying column 301 is installed on the upper surface of the rotary table 202 by a threaded connection. At the same time, the second force-applying column 302 slides in the column slide rail 206 through the lower limit nut 305, so as to adjust the position of the second force-applying column 302. After the adjustment is completed, the position of the second force-applying column 302 is fixed by tightening the limit nut 305. The abutment plate 306 provides a limit for the steel bar when it is bent. The abutment plate 306 is supported by the reinforcing angle bracket 307 and the abutment block 308 against the inner surface of the column slide rail 206.
