Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a rebar straightening device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project, which is the process of building various types of buildings. Reinforcing bars are commonly used in construction, and the amount of reinforcing bars used is very large. Before use or when recycling old and bent reinforcing bars, reinforcing bar straightening devices are needed to straighten the reinforcing bars.

[0003] For example, patent document CN221620664U discloses a rebar straightening device for building construction. It uses a first electric telescopic rod to move a lifting plate downwards, causing the straightening rollers between the connecting plates to initially straighten the rebar on the straightening table. The first and second straightening rollers then further straighten the rebar. However, since the straightening rollers, the first straightening roller, and the second straightening roller are all horizontally positioned, they can only straighten the rebar on a horizontal plane. That is, the rebar appears straight on a horizontal plane after straightening, but from a top-down view, it may still appear bent. Therefore, multiple straightening operations are generally required, resulting in insufficient effectiveness. Furthermore, the straightening rollers wear down over time, and the current rebar straightening device is not convenient for replacing the straightening rollers, making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a steel reinforcement straightening device for building construction in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A rebar straightening device for building construction includes a frame and a pulling mechanism. A vertical plate is fixed inside the frame, and the pulling mechanism is located behind the vertical plate. A through hole is opened in the middle of the vertical plate. A rotating mechanism is set on the vertical plate, and an adjusting mechanism is set in front of the rotating mechanism. A straightening mechanism is set in front of the adjusting mechanism. The straightening mechanism includes two hollow shells arranged symmetrically on the left and right. The opposite surfaces of the two hollow shells are recessed inward to form a receiving groove. A straightening roller is set in the receiving groove. A knob is rotatably connected to one side of the hollow shell. One end of the knob extends into the hollow shell and is fixed with an elliptical top wheel. Movable rods are symmetrically arranged on the upper and lower sides of the top wheel. The movable rods are slidably connected inside the hollow shell. A spring is fixed between the movable rod and the inner wall of the hollow shell. A limit sleeve is fixed to the end of the movable rod near the straightening roller. The limit sleeve can enter the receiving groove and fit on the upper and lower ends of the straightening roller.

[0007] Preferably, the rotating mechanism includes a first motor, which is fixedly connected to the rear side of the upright plate. The output shaft of the first motor is fixedly connected to a gear, which meshes with a gear ring. The gear ring is rotatably mounted on the front side of the upright plate, and the gear ring is coaxial with the through hole.

[0008] Preferably, a rotating ring is fixedly connected to the rear side of the gear ring, and an arc-shaped groove is provided on the front side of the upright plate. Both the rotating ring and the arc-shaped groove have T-shaped cross sections, and the rotating ring slides within the arc-shaped groove.

[0009] Preferably, the adjustment mechanism includes two adjustment blocks, which are respectively fixedly connected to the rear side of two hollow shells. A bidirectional lead screw and a guide rod are provided inside the adjustment blocks. The bidirectional lead screw is threadedly connected to the adjustment block, and the guide rod is slidably connected to the adjustment block. Connecting blocks are provided at both ends of the bidirectional lead screw and the guide rod. The bidirectional lead screw is rotatably connected to the connecting blocks, and the guide rod is fixedly connected to the connecting blocks. The connecting blocks are fixedly connected to the front side of the gear ring.

[0010] Preferably, a support plate is fixedly connected to the front side of the frame, and a guide cylinder is fixedly connected to the support plate. The guide cylinder is coaxial with the through hole, and the through hole is located on the front side of the correction mechanism.

[0011] Preferably, the material pulling mechanism includes two hydraulic cylinders, which are fixedly connected to the inner walls of the top and bottom of the frame, respectively. The output end of the hydraulic cylinder is fixedly connected to a roller frame, and a material pulling roller is rotatably connected inside the roller frame. A second motor is fixedly connected to one side of one roller frame, and the output shaft of the second motor is fixedly connected to the material pulling roller.

[0012] The beneficial effects are as follows: The straightening roller of this device can be detachably installed on the hollow shell. By rotating the knob, the two movable rods are moved away from each other, and the movable rods drive the limiting sleeve away from the straightening roller, thereby releasing the limiting of the straightening roller. In this way, the straightening roller can be easily removed and replaced with a new one. After the knob is released, the limiting sleeve will automatically limit the straightening roller, making the disassembly and installation of the straightening roller extremely convenient. By setting an adjustment mechanism to change the distance between the two straightening rollers, it can accommodate steel bars of different diameters. By setting a rotation mechanism to make the straightening roller rotate around the steel bar, the steel bar can be straightened comprehensively, and the steel bar can be straightened in one go, making it more convenient to use and with better straightening effect.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-8 As shown, a rebar straightening device for building construction includes a frame 1 and a pulling mechanism 6. The pulling mechanism 6 is used to pull the rebar to move. A vertical plate 2 is fixed inside the frame 1 by screws. The pulling mechanism 6 is located on the rear side of the vertical plate 2. A through hole 201 is opened in the middle of the vertical plate 2 for the rebar to pass through. A rotating mechanism 3 is provided on the vertical plate 2. An adjusting mechanism 4 is provided in front of the rotating mechanism 3. A straightening mechanism 5 is provided in front of the adjusting mechanism 4. The straightening mechanism 5 includes two hollow shells 501 arranged symmetrically on the left and right. The opposite surfaces of the two hollow shells 501 are recessed inward to form a receiving groove. A straightening roller 502 is provided in the receiving groove. The adjusting mechanism 4 is used to adjust the distance between the two straightening rollers 502 to accommodate rebars of different diameters. The rotating mechanism 3 is used to make the straightening rollers 502 rotate around the rebar. A knob 503 is rotatably connected. One end of the knob 503 extends into the hollow shell 501 and is fixed with an elliptical top wheel 504. The top wheel 504 has symmetrical movable rods 505 on its upper and lower sides. The movable rods 505 are slidably connected inside the hollow shell 501. A spring 506 is fixed between the movable rods 505 and the inner wall of the hollow shell 501. Under the elastic force of the spring 506, the movable rods 505 always press against the top wheel 504. When the top wheel 504 rotates, it will push the two movable rods 505 away from each other. A limiting sleeve 507 is fixed to the end of the movable rod 505 near the straightening roller 502. The limiting sleeve 507 can enter the receiving groove and fit over the upper and lower ends of the straightening roller 502. The limiting sleeve 507 installs the straightening roller 502 in the receiving groove of the hollow shell 501 and allows the straightening roller 502 to rotate freely.

[0028] The rotating mechanism 3 includes a first motor 301, which is fixedly connected to the rear side of the upright plate 2 by bolts. The output shaft of the first motor 301 is fixedly connected to a gear 302, which meshes with a gear ring 303. The gear ring 303 is rotatably mounted on the front side of the upright plate 2 and is coaxial with the through hole 201.

[0029] A rotating ring 304 is fixedly connected to the rear side of the gear ring 303 by screws. An arc-shaped groove 202 is provided on the front side of the upright plate 2. Both the rotating ring 304 and the arc-shaped groove 202 have T-shaped cross sections. The rotating ring 304 slides in the arc-shaped groove 202. The arc-shaped groove 202 supports the rotating ring 304 and ensures that the rotating ring 304 and the gear ring 303 can rotate.

[0030] The adjusting mechanism 4 includes two adjusting blocks 401, which are fixedly connected to the rear side of the two hollow shells 501 by screws. A bidirectional lead screw 402 and a guide rod 403 are provided inside the adjusting block 401. The bidirectional lead screw 402 is threadedly connected to the adjusting block 401, and the guide rod 403 is slidably connected to the adjusting block 401. Connecting blocks 404 are provided at both ends of the bidirectional lead screw 402 and the guide rod 403. The bidirectional lead screw 402 and the connecting blocks 404 are rotatably connected by bearings. The guide rod 403 is fixedly connected to the connecting blocks 404. The connecting blocks 404 are fixedly connected to the front side of the gear ring 303 by screws. When the bidirectional lead screw 402 rotates, it will drive the two adjusting blocks 401 to move relative to each other. The adjusting blocks 401 drive the hollow shells 501 to move, thereby adjusting the distance between the two straightening rollers 502.

[0031] A support plate 101 is fixedly connected to the front side of the frame 1 by screws. A guide cylinder 102 is fixedly connected to the support plate 101 by screws. The guide cylinder 102 is used to guide and limit the steel bar, so that the steel bar can be stably held between the two straightening rollers 502. The guide cylinder 102 is coaxial with the through hole 201, which is located on the front side of the straightening mechanism 5.

[0032] The material pulling mechanism 6 includes two hydraulic cylinders 601, which are fixedly connected to the inner walls of the top and bottom of the frame 1 by bolts. The output end of the hydraulic cylinder 601 is fixedly connected to a roller frame 602, and a material pulling roller 603 is rotatably connected inside the roller frame 602. A second motor 604 is fixedly connected to one side of one roller frame 602, and the output shaft of the second motor 604 is fixedly connected to the material pulling roller 603.

[0033] Working principle: During use, the reinforcing bar passes sequentially from front to back through the guide cylinder 102, between the two straightening rollers 502, through the through hole 201, and between the two pulling rollers 603. Rotating the bidirectional lead screw 402 drives the two adjusting blocks 401 to move closer together. The adjusting blocks 401 move the hollow shell 501, which in turn moves the two straightening rollers 502 closer together and presses down on the reinforcing bar. The hydraulic cylinder 601 drives the roller frame 602 to move, causing the two pulling rollers 603 to move closer together and clamp the reinforcing bar. The second motor 604 drives the pulling rollers 603 to rotate, pulling the reinforcing bar forward. The straightening rollers 502 straighten the reinforcing bar. During the straightening process, the first motor 301 drives the gear 302 to rotate, which in turn drives the gear ring 303 to rotate, causing the straightening rollers 502 to rotate around the reinforcing bar, thus achieving comprehensive straightening and a good straightening effect.

[0034] When the straightening roller 502 needs to be replaced, turn the knob 503. The knob 503 drives the top wheel 504 to rotate. The top wheel 504 pushes the two movable rods 505 away from each other, and the spring 506 is compressed. The movable rods 505 drive the two limiting sleeves 507 away from each other. The limiting sleeves 507 enter the hollow shell 501. At this time, the limiting sleeves 507 release the restriction on the straightening roller 502, and the straightening roller 502 can be directly removed from the hollow shell 501 and replaced with a new straightening roller 502. Loosen the knob 503, the spring 506 rebounds and pushes the movable rod 505 to reset. The movable rod 505 drives the limiting sleeves 507 to reset. The limiting sleeves 507 extend into the receiving groove of the hollow shell 501 and fit over the upper and lower ends of the straightening roller 502, completing the installation of the straightening roller 502.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
