Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, specifically referring to a bending machine for building steel reinforcement frames. Background Technology

[0002] In the field of construction engineering, the processing of steel reinforcement frames is an important process. Traditional five-head bending machines use a positioning plate to position one side of the steel reinforcement during the bending operation. The position of the positioning plate is fixed and cannot be flexibly adjusted to meet the placement requirements of steel reinforcement of different widths and specifications. This makes it difficult to accurately position the steel reinforcement during the bending operation, and often requires manual support of the steel reinforcement to ensure its stable position during the bending process. Manual operation poses safety hazards and can easily lead to hand injuries to workers due to improper operation.

[0003] In addition, existing bending machines lack effective limiting at the far end of the bending shaft. During the bending process, the far end of the reinforcing bar is not reliably constrained, which can easily lead to problems such as inaccurate bending angle and reinforcing bar deviation, thereby affecting the processing quality of the reinforcing bar frame and reducing the product qualification rate. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a bending machine for building steel reinforcement frames, which effectively solves the problems of inconvenient adjustment of the positioning plate and lack of limit at the far end of the bending shaft.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a bending machine for building steel reinforcement frames includes a movable base, a machine head on the movable base, a rotating head on the machine head, a bending shaft on the rotating head, a central shaft passing through the center of the rotating head, a pad on the movable base, a sliding positioning plate at the far end of the central shaft and the bending shaft, an adjustment component at the connection between the positioning plate and the movable base, a positioning groove on the positioning plate, the far end of the bending shaft passing through the positioning groove, and the outer side of the bending shaft and the inner sidewall of the positioning groove being in close contact.

[0006] Preferably, the adjusting assembly includes a threaded rod and a limiting rod, the positioning plate is slidably disposed on the movable base, the threaded rod and the positioning plate are threadedly connected and rotatably disposed on the movable base, one end of the threaded rod is fixed with a handwheel, and the movable base is also provided with a limiting rod that penetrates the positioning plate.

[0007] Preferably, the positioning groove is arc-shaped and coaxial with the central axis of the curved shaft.

[0008] Preferably, the positioning plate is provided with positioning holes corresponding to the central axis.

[0009] Preferably, the positioning plate is further provided with a limiting groove, the pad is a cuboid, and the width and height of the limiting groove are both greater than the side width and height of the pad.

[0010] Preferably, the bottom of the pad is provided with two sets of symmetrical snap-fit ​​grooves, and the movable base is provided with two sets of snap-fit ​​blocks that match the snap-fit ​​grooves.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. By setting a positioning groove on the positioning plate that is identical to the bending shaft trajectory, the far end of the bending shaft is limited, which effectively constrains the deformation path of the steel bar during bending, ensuring that the angle and shape of each bend meet the design requirements, greatly improving the processing quality of the steel bar frame, reducing the scrap rate caused by bending errors, and improving overall production efficiency.

[0013] 2. The adjustable positioning plate can accommodate steel bars of different widths, eliminating the need for manual handling of the steel bars, reducing the chance of workers coming into contact with moving parts of the equipment, effectively avoiding safety accidents caused by operational errors, and providing a safer working environment for operators.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, the bending machine for building steel reinforcement frames proposed in this utility model includes a movable base 1, a machine head 2 on the movable base 1, a rotating head 3 on the machine head 2, a bending shaft 4 on the rotating head 3, a central shaft 5 passing through the center of the rotating head 3, a pad 6 placed on the movable base 1 for placing steel reinforcement, a sliding positioning plate 7 located at the far end of the central shaft 5 and the bending shaft 4, an adjustment component 8 at the connection between the positioning plate 7 and the movable base 1 for adjusting the position of the positioning plate 7, a positioning groove 9 on the positioning plate 7, the far end of the bending shaft 4 passing through the positioning groove 9, the outer side of the bending shaft 4 and the inner side wall of the positioning groove 9 being in close contact to limit the far end of the bending shaft 4.

[0023] like Figure 4 As shown, the adjustment assembly 8 includes a threaded rod 10 and a limiting rod 11. The positioning plate 7 is slidably mounted on the movable base 1. The threaded rod 10 and the positioning plate 7 are threadedly connected and rotatably mounted on the movable base 1. A handwheel 12 is fixed to one end of the threaded rod 10. The movable base 1 is also provided with a limiting rod 11 that passes through the positioning plate 7 to limit the positioning plate 7. Rotating the handwheel 12 drives the threaded rod 10 to rotate, and the threaded rod 10 drives the positioning plate 7 to move, thereby adjusting the position of the positioning plate 7.

[0024] like Figure 4 , 5As shown, the positioning groove 9 is arc-shaped and coaxial with the central axis 5 of the bent shaft 4, allowing the bent shaft 4 to move within the positioning groove 9. The positioning plate 7 is provided with positioning holes 14 corresponding to the central axis 5 to position the central axis 5. The positioning plate 7 is also provided with a limiting groove 13. The pad 6 is a cuboid. The width and height of the limiting groove 13 are both greater than the side width and height of the pad 6, making it easier for the positioning plate 7 to pass through the pad 6.

[0025] like Figure 2 As shown, the bottom of the pad 6 is provided with two sets of symmetrical snap-fit ​​grooves 15, and the movable base 1 is provided with two sets of snap-fit ​​blocks 16 that match the snap-fit ​​grooves 15 to limit the pad 6 and facilitate the removal and replacement of the pad 6.

[0026] In practical use, the positioning plate 7 is adjusted according to the width of the steel bar frame to be processed. The snap-fit ​​groove 15 is aligned with the snap-fit ​​block 16. The pad is placed on the movable base 1, and the steel bar is placed on the pad 6. The handwheel 12 is turned to drive the threaded rod 10 to rotate. The threaded rod 10 drives the positioning plate 7 to move, so that the positioning plate 7 is close to one side of the steel bar. The central shaft 5 is extended into the positioning hole 14 to press the steel bar. The rotating head 3 drives the bending shaft 4 to rotate and bend the steel bar. During the rotation of the bending shaft 4, it rotates in the positioning groove 9. The positioning groove 9 limits the bending shaft 4 and increases the stability of the bending.

[0027] After the steel bar completes a bending action, the angle or position of the five-head bending device is adjusted by the control system according to the design of the steel bar frame to carry out the next bending process until the bending process of the entire steel bar frame is completed.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
