Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel bar bending, and particularly relates to a building construction steel bar bending device. BACKGROUND

[0002] In the field of building construction, steel bars are important materials for building the skeleton of a building, and steel bar bending is one of the key links in the steel bar processing process. Accurate and efficient bending of steel bars is crucial for ensuring the stability and safety of building structures and meeting design requirements. Traditional steel bar bending methods mainly rely on manual operation with simple tools. This method not only has high labor intensity and low efficiency, but also cannot guarantee the consistency of bending accuracy. With the development of the construction industry, the efficiency and quality requirements for steel bar processing are continuously improving, and some automatic steel bar bending devices have gradually appeared. However, these devices have certain limitations.

[0003] Most steel bar bending devices on the market are usually electric or hydraulic drive automatic bending devices. When these automatic bending components fail, the entire device cannot work normally, causing the steel bar bending work to stop, which seriously affects the construction progress. For example, in some large construction projects, the demand for steel bars is huge. Once the bending device fails, a large amount of time and manpower will be wasted during the maintenance period, increasing the construction cost. Therefore, the utility model is proposed.

[0007] In order to facilitate the replacement of the first rotating sleeve, the second rotating sleeve and the third rotating sleeve when they are damaged, the first bolt and the second bolt are inserted into the L-shaped plate, the first insertion slot matched with the first bolt and the second bolt is formed in the fixed disc, the third bolt is inserted into the U-shaped plate, and the second insertion slot matched with the third bolt is formed in the U-shaped plate.

[0008] In order to reduce the force applied by the staff to the U-shaped plate, further, a plurality of embedding grooves are circumferentially and equidistantly formed in positions of the fixed disc and the L-shaped plate close to the U-shaped plate, the rolling balls are movably connected in the embedding grooves, and the rolling balls are attached to the U-shaped plate.

[0013] Whether automatic or manual bending, the design of the fixed disc, the bolt and the rotating sleeve and other components in the device helps to ensure the accuracy of the reinforcing steel bar bending. When automatic bending, the accurate thrust control of the arc hydraulic cylinder and the cooperation of the components can ensure the accuracy of the reinforcing steel bar bending angle; when manual bending, the staff can use the scale and other auxiliary tools on the fixed disc to accurately control the bending angle, ensure that the bending quality of each reinforcing steel bar meets the construction requirements, and thus ensure the stability and safety of the building structure.

[0026] When the steel bar is bent, the staff first carries the device to the designated position, then fixes the bottom plate 1 on the ground through the expansion bolt, and then places the part of the steel bar to be bent between the first rotating sleeve 404, the second rotating sleeve 405 and the third rotating sleeve 406, when the automatic bending part (the oil supply part 5 and the arc hydraulic cylinder 501 are normally operated) in the device, the device provides hydraulic oil for the arc hydraulic cylinder 501 through the oil supply part 5, uses the hydraulic principle to make the telescopic end of the arc hydraulic cylinder 501 generate the thrust, when the arc hydraulic cylinder 501 works, the telescopic end is in abutment with the U type board 407, pushes the U type board 407 to rotate around the second bolt 402, along with the rotation of the U type board 407, the steel bar is bent under the restriction of the first rotating sleeve 404, the second rotating sleeve 405 and the third rotating sleeve 406, by controlling the angle of rotation of the U type board 407, the steel bar can be bent into a specific angle, in the process, the first rotating sleeve 404, the second rotating sleeve 405 and the third rotating sleeve 406 on the first bolt 401, the second bolt 402 and the third bolt 403 can rotate together according to the steel bar, reduce the friction between the steel bar and each part, make the rotation more smooth, ensure the accuracy and stability of the automatic bending action.
