Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a steel bar bending device for construction. Background Art
[0002] In the construction industry, rebar, a crucial reinforcement material in concrete structures, has a significant impact on its shape and size, directly impacting the stability and safety of building structures. The continuous advancement of modern construction technology has placed higher demands on the precision and efficiency of rebar processing. In particular, in projects such as high-rise buildings, large bridges, and highways, the bending shape and angle of rebar must be strictly controlled to meet complex structural design and construction requirements.
[0003] Traditional rebar bending is mostly done manually, a method that is not only inefficient but also difficult to achieve with guaranteed accuracy and consistency. Furthermore, manual operation poses safety risks, making it easy for operators to be injured during the bending process. Therefore, developing efficient, precise, and safe rebar bending equipment is crucial.
[0004] Several rebar bending machines are currently available on the market. Most use an electric motor to drive a force transmission system, feeding the rebar into a bending mechanism for bending. These devices typically consist of two main components: a clamping device and a bending mechanism. The clamping device secures the rebar to prevent it from slipping or falling out of the bending mechanism during the bending process; the bending mechanism uses rollers to squeeze the rebar. However, these devices still have some shortcomings when it comes to curved rebar bending. Specifically, they typically use a one-shot process, resulting in imprecise bending angle control, inconsistent bending shapes, and complex operation. Utility Model Content

[0028] Example
[0029] Please refer to Figure 1-Figure 4 The present embodiment provides a steel bar bending device for construction, comprising: a support mechanism 1; a bending mechanism 2, the bending mechanism 2 comprising a guide wheel 201 and a bending wheel 202, there are two guide wheels 201, the two guide wheels 201 are symmetrically arranged on the support mechanism 1, and the guide wheels 201 are rotatably arranged on the support mechanism 1, and the bending wheel 202 is raised and lowered on the support mechanism 1, and positioning grooves 3 adapted to the size of the steel bars to be bent are provided on the guide wheels 201 and the bending wheels 202, wherein a rotating seat 4 for mounting the guide wheels 201 is provided on the support mechanism 1, and the rotating seat 4 is slidably arranged on the support mechanism 1, and the two guide wheels 201 can slide freely along the support mechanism 1.
[0030] In this embodiment, the supporting mechanism 1 is used to install the bending mechanism 2, so as to facilitate lifting the bending mechanism 2 to perform bending operations.
[0031] In this embodiment, the bending mechanism 2 is used to perform arc bending operations on steel bars. Specifically, the guide wheel 201 is used to guide the transportation of steel bars. There are two guide wheels 201, and a bending wheel 202 for bending the steel bars is arranged between the two guide wheels 201. Through the coordinated action of the guide wheel 201 and the bending wheel 202, the vertical steel bars are bent into annular steel bars, thereby improving the convenience of bending the steel bars.
[0032] The positioning slots 3 are used to adjust the spacing between the two guide wheels 201. This allows for adjustment of the radius of the rebar bend, facilitating the production of rebar rings of varying diameters and expanding their applicability. Furthermore, the radius of the rebar ring can be adjusted by driving the guide wheels 201, allowing for precise adjustments to product accuracy based on specific needs, facilitating subsequent installation.
[0033] It should be noted that reasonable bending process parameters, such as bending radius and bending speed, should be adopted to reduce stress concentration and plastic deformation inside the steel bar. At the same time, the quality and accuracy of the bending equipment should be ensured to avoid damage to the steel bar due to equipment problems. The bending radius of the steel bar can be effectively adjusted by adjusting the spacing of the guide wheels 201 and controlling the downward pressure distance of the bending wheel 202. The bending speed of the steel bar can be effectively controlled by controlling the speed of the guide wheels 201, which can effectively avoid the generation of material cracks when the steel bar is bent, and can ensure the structural strength of the finished steel bar ring.
[0034] Please refer to Figure 3 In some implementations of this embodiment, a strip hole 5 is opened on the above-mentioned support mechanism 1, and the rotating seat 4 moves along the opening direction of the strip hole 5. The rotating seat 4 and the support mechanism 1 are connected by a screw 6, and the screw 6 passes through the rotating seat 4 and the strip hole 5 in turn.
[0035] In this embodiment, the strip-shaped hole 5 is used to adjust the position of the rotating seat 4 on the support mechanism 1. By adjusting the distance between the two rotating seats 4, the guide wheel 201 can be moved along the direction of the opening of the strip-shaped hole 5. This facilitates the movement of the guide wheel 201 by adjusting the rotating seat 4, facilitating adjustment according to the needs of the operation. Specifically, the rotating seat 4 is fixed to the support mechanism 1 by screws 6. Loosening the screws 6 allows the rotating seat 4 to slide, and then the rotating seat 4 can be fixed again.
[0036] Please refer to Figure 3 In some implementations of this embodiment, a scale belt 7 is provided on the support mechanism 1 , and the scale belt 7 is parallel to the rotating base 4 .
[0037] In this embodiment, the above-mentioned scale tape 7 is used for user reference to adjust the distance of the rotating seat 4 so that the moving distance of the two rotating seats 4 remains consistent, so as to ensure that the bending wheel 202 is in the middle of the two rotating seats 4, thereby ensuring the bending curvature, thereby facilitating the improvement of the accuracy of the steel bar bending.
[0038] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, the support mechanism 1 is provided with a drive motor 8 for driving the guide wheel 201 to rotate, the output end of the drive motor 8 is provided with a first sprocket 9, the guide wheel 201 is provided with a second sprocket 10, and the first sprocket 9 and the second sprocket 10 are connected by a chain 11.
[0039] In this embodiment, the drive motor 8 is used to drive the two guide wheels 201 to rotate synchronously, thereby driving the steel bar. When in use, one end of the steel bar to be bent is placed in the positioning groove 3 of any guide wheel 201, the bending wheel 202 is driven downward, and the drive motor 8 is started. The drive motor 8 drives the guide wheel 201 to rotate, and the rotation of the guide wheel 201 drives the steel bar to continuously move along the bending wheel 202 to form an arc structure. Specifically, the first sprocket 9 rotates synchronously with the power shaft of the drive motor 8. The rotation of the first sprocket 9 drives the chain 11, so that the second sprocket 10 starts to rotate along with the first sprocket 9, synchronously driving the guide wheel 201, and driving the steel bar to continuously move on the guide wheel 201.
[0040] Preferably, the drive motor 8 is a servo motor, which controls the operation of mechanical components in a servo system and serves as an auxiliary motor for indirect transmission. A servo motor can control speed with high precision, converting voltage signals into torque and speed to drive the controlled object. The excellent control accuracy of servo motors makes them ideal materials for the drive motor 8, but the materials are not limited to the aforementioned servo motors; other materials with similar performance can also be used.
[0041] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, a reducer 12 is provided between the first sprocket 9 and the second sprocket 10 .
[0042] In this embodiment, the reducer 12 is a standalone component comprised of a gear drive, worm drive, or gear-worm drive enclosed within a rigid housing. It is commonly used as a reduction gear between the prime mover and the working machine. The reducer 12 converts the high-speed rotation of the drive motor 8 into the low-speed rotation of the bending wheel. While reducing the rotational speed, the reducer 12 significantly increases the torque of the output shaft. This enables the rebar bending mechanism 2 to easily handle the bending requirements of large-diameter, high-strength rebar.
[0043] Please refer to Figure 1-Figure 3In some implementations of this embodiment, the above-mentioned support mechanism 1 includes a base 101 and a workbench 102, a guide cylinder 13 is provided on the base 101, and a sliding column 14 adapted to the guide cylinder 13 is provided at one end of the workbench 102 close to the base 101. The sliding column 14 is slidably set in the guide cylinder 13, and an adjustment mechanism for tensioning the chain 11 is provided between the base 101 and the workbench 102.
[0044] In this embodiment, the base 101 and the work platform 102 cooperate with each other to address the situation where the chain 11 becomes loose after the rotating base 4 is adjusted. By adjusting the distance between the base 101 and the work platform 102, the chain 11 can be effectively tightened, preventing the chain 11 from separating from the first gear and the second gear, thereby improving the stable operation of the equipment. The adjustment mechanism is used to adjust and fix the distance between the base 101 and the work platform 102.
[0045] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, the above-mentioned adjustment mechanism includes an adjusting screw rod 15 that passes through the workbench 102. The screw rod passes through one end of the workbench 102 and is rotatably set on the base 101. The adjusting screw rod 15 is threadedly connected to the workbench 102. A driving handle 16 is set at the end of the adjusting screw rod 15 away from the base 101.
[0046] In this embodiment, the above-mentioned adjusting screw 15 is used to drive the adjusting screw 15 to rotate by hand, so that relative displacement occurs between the base 101 and the workbench 102, which is convenient for corresponding control according to adjustment requirements, greatly improving the convenience and stability of equipment operation.
[0047] When in use, the steel bars are placed on the two guide wheels 201 and the drive motor 8 is started. While the drive motor 8 is working, the bending wheel 202 is driven downward to make the strip steel bars or large-diameter steel bars into steel bars of the target diameter. When adjusting the diameter of the steel bars, the two symmetrically arranged rotating seats 4 are moved on the support mechanism 1, and the distance between the moving rotating seats 4 and the bending wheel 202 is kept consistent with the scale lines of the scale tape 7. Then the adjusting screw 15 is rotated to tighten the chain 11 and the machine can be restarted.
[0048] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
