Description

Technical Field

[0001] This invention relates to the field of building construction, and more specifically to a steel bar bending device for building engineering. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. They have a circular cross-section, sometimes a square with rounded corners; they include various types such as plain round bars, ribbed bars, and twisted bars, and are widely used in building construction.

[0003] In existing construction projects, the construction quality of steel reinforcement is a key focus of quality control. When bending the ends of tie bars, stirrups, and end bars involved in steel reinforcement, manual operation is generally used. Without the corresponding tools, it is not easy to control the construction quality. This is especially true for narrow parts where the operation is not fixed, where the bending of steel reinforcement is even more difficult.

[0004] Therefore, in order to solve the above problems, a steel bar bending device for construction engineering is needed to solve the aforementioned production issues. Summary of the Invention

[0005] In view of this, the steel bar bending device for building engineering in this technical solution, by installing the bending component inside the housing, the drive mechanism drives the bending component to move and cooperates with the limit gate mechanism to limit the steel bar, so as to achieve effective bending of the steel bar. The overall structure is simple, easy to operate, and highly versatile, and can solve the problem of difficult bending of steel bars after the steel bar construction is completed.

[0006] A steel bar bending device for construction engineering includes a housing, a bending component installed inside the housing, a drive mechanism that provides power input to the bending component, and a limiting gate mechanism that is installed in conjunction with the housing; the steel bar is bent through the limiting gate mechanism and the bending component.

[0007] Furthermore, the bending assembly includes a bending turbine disk rotatably mounted inside the housing and a worm gear meshing with the bending turbine disk for transmission. The drive mechanism drives the worm gear to rotate, thereby driving the bending turbine disk to rotate to achieve bending of the reinforcing bar.

[0008] Furthermore, the bent turbine disk has a fan-shaped notch, which is recessed inward to form a turbine disk groove for bending the reinforcing bars.

[0009] Furthermore, the front end of the housing extends outward to form a U-shaped guide groove, and the limiting door mechanism is installed at the end of the U-shaped guide groove.

[0010] Furthermore, the limiting gate mechanism includes a positioning arm installed on one side of the U-shaped guide groove, an L-shaped gantry hinged to the positioning arm, a locking arm hinged to the L-shaped gantry and installed on the other side of the U-shaped guide groove, and a limiting pressure plate assembly. The limiting pressure plate assembly is installed in conjunction with the L-shaped gantry and is used to support and limit the bending of the reinforcing bars.

[0011] Furthermore, the limiting pressure plate assembly includes a rotating rod and a limiting pressure plate installed at the end of the rotating rod. The rotating rod has a threaded structure, and the L-shaped gantry has a threaded hole in the middle. The rotating rod passes through the L-shaped gantry and forms a screw and nut pair structure.

[0012] Furthermore, the limiting pressure plate has a recessed center to form a pressure plate notch that matches the bending of the reinforcing bars.

[0013] Furthermore, a support plate is installed inside the U-shaped guide groove, and an arc-shaped slot is formed on the support plate.

[0014] The beneficial effects of this invention are:

[0015] This technical solution for a steel bar bending device in construction engineering involves installing a bending component inside a housing. A drive mechanism moves the bending component and, in conjunction with a limiting gate mechanism, limits the steel bar, thus achieving effective bending. The device has a simple overall structure, is easy to operate, and is highly versatile, solving the problem of difficult steel bar bending after construction. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] Figure 1 This is a schematic diagram of the overall structure of the present invention;

[0018] Figure 2 This is a schematic diagram of the internal installation of the housing of the present invention. Detailed Implementation

[0019] Figure 1 This is a schematic diagram of the overall structure of the present invention; Figure 2This is a schematic diagram of the internal installation of the housing of the present invention. As shown in the figure, a steel bar bending device for construction engineering includes a housing 3, a bending component installed inside the housing, a drive mechanism 2 that provides power input to the bending component, and a limiting gate mechanism installed in conjunction with the housing. The steel bar 8 is bent through the limiting gate mechanism and the bending component. The outer shell of the drive mechanism 2 is installed in conjunction with the housing 3. The drive mechanism 2 is equipped with a deceleration mechanism inside, which can provide a greater output torque for its bending component (of course, its internal drive mechanism and deceleration mechanism are installed and set using existing technology, which will not be described in detail here). The handle 1 is installed in conjunction with the drive mechanism 2 for convenient hand operation. The steel bar bending device for construction engineering of this technical solution, by installing the bending component inside the housing, the drive mechanism drives the bending component to move and cooperates with the limiting gate mechanism to limit the steel bar, realizes effective bending of the steel bar. The overall structure is simple, easy to operate, and highly versatile, and can solve the problem of difficulty in bending the steel bar or the angle not meeting the standard after the steel bar is installed.

[0020] In this embodiment, the bending assembly includes a bending turbine disk 4 rotatably mounted within the housing 3 and a worm gear 14 meshing with and driving the bending turbine disk 4. The driving mechanism drives the worm gear 14 to rotate, thereby driving the bending turbine disk to rotate and achieve bending of the reinforcing bar 8. Figure 2 As shown, the bending assembly adopts a worm gear mechanism. The power output end of the drive mechanism 2 drives the worm gear 14 to rotate and drives the bending worm disk 4 to rotate, thereby bending the end steel bar 8. The worm gear mechanism has a self-locking effect, which prevents the steel bar from springing back and causing safety accidents.

[0021] In this embodiment, the bent turbine disk 4 has a fan-shaped notch, and the fan-shaped notch is recessed inward to form a turbine disk groove 41 for bending the reinforcing bar. Figure 1 Figure 2 As shown, the bending turbine disk 4 does not adopt a complete turbine disk structure. Instead, a fan-shaped notch structure is machined on the turbine disk (a non-standard fan-shaped structure, whose notch machining does not pass through the center position, affecting the installation of the turbine disk). The surface of the fan-shaped notch is recessed inward to form a turbine disk groove 41 structure, which facilitates the guiding and limiting effect when bending the reinforcing bar 8, making it convenient for bending the reinforcing bar.

[0022] In this embodiment, the front end of the housing 3 faces outward ( Figure 1 The U-shaped guide groove 7 is formed by extending upwards from the center, and the limiting gate mechanism is installed at the end of the U-shaped guide groove. The front end of the housing 3 extends to form the U-shaped guide groove 7 structure, which facilitates the guiding and limiting of the reinforcing bars. The limiting gate mechanism is set at the inner end of the guide groove to facilitate the limiting of the reinforcing bars when they are bent.

[0023] In this embodiment, the limiting gate mechanism includes a positioning arm 9 installed on one side of the U-shaped guide groove 7, an L-shaped gantry 11 hinged to the positioning arm 9, a locking arm 5 hinged to the L-shaped gantry 11 and installed on the other side of the U-shaped guide groove, and a limiting pressure plate assembly. The limiting pressure plate assembly is installed with the L-shaped gantry 11 and is used to support and limit the bending of the reinforcing bar 8. The positioning arm 9 is fixedly installed on one side of the U-shaped guide groove 7, and the locking arm 5 is lockably installed on the other side of the U-shaped guide groove 7. The two ends of the L-shaped gantry 11 are hinged to the positioning arm 9 and the locking arm 5, respectively. After the three are installed in place, they form a limiting gantry structure, which provides a support installation point for the limiting pressure plate assembly. When the reinforcing bar is bent in place, the locking arm 5 can be opened (the locking arm 5 can be installed with the side wall of the U-shaped guide groove 7 by snap-fit, pin limiting, or other methods; existing technology is acceptable here), facilitating the next bending.

[0024] In this embodiment, the limiting pressure plate assembly includes a rotating rod 12 and a limiting pressure plate 10 installed at the end of the rotating rod 12. The rotating rod 12 has a threaded structure, and the L-shaped gantry 11 has a threaded hole in the middle. The rotating rod passes through the L-shaped gantry and forms a screw and nut pair structure. After the rotating rod 12 is installed with the threaded hole in the middle of the L-shaped gantry 11, a screw and nut pair structure is formed, which facilitates the adjustment of the installation height of the rotating rod 12, thereby allowing the limiting pressure plate 10 to better press the reinforcing bar for bending.

[0025] In this embodiment, the limiting pressure plate 10 has a recessed center to form a pressure plate notch 6 for bending the reinforcing bar. The notch 6 in the center of the limiting pressure plate 10 facilitates better positioning and bending of the reinforcing bar, ensuring construction quality.

[0026] In this embodiment, a support plate 13 is installed inside the U-shaped guide groove 7, and the support plate 13 has an arc-shaped groove. Figure 2 As shown, the support plate 13 and the limiting pressure plate assembly are at the same horizontal position. An arc-shaped slot structure is provided on the support plate 13, which, together with the pressure plate recess 6 structure, provides a better limiting effect when the steel bar is bent, thus ensuring the bending quality.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
