Description

A steel bar bending device and a steel bar cold bending processing method Technical Field

[0001] This invention relates to the field of building technology, specifically to a steel bar bending device. Background Technology

[0002] The mechanical bending of metal sheets, strips, and tubes into specific shapes and dimensions at room temperature using bending equipment is called cold bending. The advantages of cold bending are: it allows the production of various ultra-thin, ultra-wide, and complex-shaped profiles that cannot be produced by rolling; it saves metal materials; and it produces products with good mechanical properties. Commonly used cold bending methods include roll bending, pressure bending, drawing bending, and folding bending.

[0003] Rebar hoops are small building profiles cold-bent using bending equipment on construction sites. The most common type is the U-shaped hoop, open at both ends, with a typical length of 1-2 meters. To improve efficiency, construction workers often place 3-5 rebars at a time on the bending equipment for batch cold bending. However, existing bending equipment lacks auxiliary mechanisms to align and secure the rebars, making it difficult to align them within the same batch. This leads to movement between rebars during processing, resulting in significant dimensional differences and inconsistencies among the hoops formed in the same batch, causing inconvenience for subsequent construction. Furthermore, on construction sites, large quantities of rebar hoops are often stacked without proper securing mechanisms, making the stacks unstable, prone to tilting or even collapse, posing safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a steel bar bending device and a steel bar cold bending processing method, which aims to overcome the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rebar bending device includes a base with a worktable. A turntable is rotatably mounted on the worktable. A central column and an eccentric component are fixedly mounted on the turntable. A channel for vertically stacking multiple rebars is formed between the central column and the eccentric component. A limiting plate is fixedly mounted on the right side of the channel. The limiting plate has multiple strip-shaped guide grooves arranged vertically for abutting against the sidewalls of the rebars, and the strip-shaped guide grooves are aligned with the channel. A binding device is also provided between the limiting plate and the channel on the worktable. The binding device includes a material trough, a movable plate, and a cap. The material trough is used to vertically place the cap, and a discharge port is provided at the bottom of the material trough. The movable plate is movably mounted on the material trough for opening and closing the discharge port. A receiving groove is provided on the right side of the front end of the movable plate.

[0007] The aforementioned receiving groove includes a back plate, a rear limiting strip, and a front limiting strip. The front right side of the aforementioned movable plate is provided with a material discharge port. The aforementioned back plate for fitting the left end of the cap is fixed below the material discharge port on the movable plate. The rear end of the back plate is fixed with a rear limiting strip, and the front end is provided with a front limiting strip that can be rotated and opened and closed. The lower ends of the rear limiting strip and the front limiting strip are symmetrically provided with limiting protrusions for supporting the cap.

[0008] The right end of the cap has multiple vertically arranged butt grooves for inserting reinforcing bars.

[0009] Furthermore, the cap includes a plastic shell and multiple magnets. The plastic shell has multiple cylindrical bodies arranged vertically, and each cylindrical body is fixedly embedded with one of the aforementioned magnets. The plastic shell has protrusions integrally formed and symmetrically arranged at the four positions (top, bottom, front, and back) of each cylindrical body to form a mating groove. The end face of the protrusion facing the center of the cylindrical body is in contact with the side wall of the reinforcing bar. The two adjacent protrusions are connected to each other as a whole. The outer circumferential diameter of the cylindrical body is smaller than the diameter of the reinforcing bar, and the distance between the outer walls of the two symmetrical protrusions is smaller than the diameter of the reinforcing bar.

[0010] Furthermore, the distance between the centers of two adjacent cylindrical bodies is greater than the diameter of the reinforcing bar, but less than 1.2 times the diameter of the reinforcing bar.

[0011] Furthermore, the upper surface of the aforementioned movable plate is provided with a slide rail for moving and connecting the material trough, and a reinforcing plate is also provided between the back plate and the movable plate. The lower end of the material trough is provided with a left extension plate, and the left end of the back plate is fixedly provided with a connecting ear. The aforementioned left extension plate is fixedly provided with an electric telescopic rod, and the telescopic end of the electric telescopic rod is fixedly connected to the aforementioned connecting ear.

[0012] Furthermore, the upper and lower ends of the aforementioned front limit strip are connected to the front end of the back plate via damping pivots.

[0013] Furthermore, the lower end of the aforementioned material trough is provided with a right extension plate, which is fixedly connected to the aforementioned limiting plate.

[0014] Furthermore, a correction device is provided on the right side of the limiting plate on the worktable. The correction device includes a driving wheel and a driven wheel. The driving wheel and the two driven wheels are rotatably mounted on the worktable, and a second channel is formed between the two driven wheels and the driving wheel. The second channel is aligned with the strip guide groove.

[0015] Furthermore, both the driving wheel and the driven wheel are vertically arranged with multiple annular grooves for fitting against the sidewall of the reinforcing bar.

[0016] This invention also discloses a method for cold bending of reinforcing bars, which uses a reinforcing bar bending device with the structure described above to perform the following cold bending process on the reinforcing bars:

[0017] (1) Arrange multiple steel bars vertically into a steel bar group, and send the left end of the steel bar group into channel two from the right side of the straightening device. The driving wheel drives the steel bar group to move to the left, and the bent steel bar is straightened by the driving wheel and two driven wheels.

[0018] (2) The active wheel drives the steel bar group to move to the left, so that the left end of the steel bar group enters the strip guide groove of the limiting plate; at the same time, the movable plate of the binding device is moved forward, so that the cap inside the receiving groove is between the channel one and the strip guide groove.

[0019] (3) The drive wheel moves the steel bar group to the left, so that the left end of the steel bar group is inserted into the cap inside the receiving groove, and the drive wheel is paused;

[0020] (4) Move the movable plate of the binding device backward so that the front limit bar opens and the cap is removed from the receiving groove; continue to move the movable plate of the binding device backward so that the material drop port is located directly below the material outlet and the cap in the material trough falls into the receiving groove.

[0021] (5) The drive wheel moves the steel bar group to the left, so that the left end of the steel bar group enters channel one; when the left end of the steel bar group reaches the predetermined position, the turntable is rotated counterclockwise, and the eccentric part bends the steel bar group.

[0022] Furthermore, it also includes the following steps:

[0023] (6) Bend the reinforcing bars into reinforcing hoop;

[0024] (7) Remove the steel bar assembly from the equipment and manually attach another cap to the right end of the steel bar assembly.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] Firstly, the steel structure bending equipment of this invention is suitable for cold bending of reinforcing bars. The worktable is equipped with a binding device mainly consisting of a material trough, a movable plate, a receiving groove, and a cap between the limiting plate and the first channel. The movable plate and the receiving groove move the cap between the limiting plate and the first channel, allowing multiple vertically arranged reinforcing bars to be inserted into the cap. This achieves automatic alignment and fixation of the multiple reinforcing bars, forming a reinforcing bar group, thereby improving the consistency of the cold-bent reinforcing bars. Furthermore, during subsequent stacking of reinforcing bars, the cap can also serve as a binding and fixing component, securing the multiple reinforcing bars in the group to each other, strengthening the stability of the reinforcing bar stack, and allowing the stack to be stacked higher and more stably.

[0027] Secondly, in the binding device of the present invention, the receiving groove includes a back plate, a rear limiting strip and a front limiting strip. The rear limiting strip is fixedly provided at the rear end of the back plate, and the front limiting strip is provided at the front end in a way that can be rotated and opened and closed. The lower ends of the rear limiting strip and the front limiting strip are symmetrically provided with limiting protrusions for supporting the cap. After the steel bar group is inserted and fixed to the cap in the receiving groove, the cap can be disengaged from the receiving groove by moving the receiving groove backward. The structure is ingenious, realizes automatic feeding and insertion of the cap, and improves safety.

[0028] Thirdly, the aforementioned cap includes a plastic shell and multiple magnetic blocks. The plastic shell contains multiple vertically arranged cylindrical bodies. Each cylindrical body has integrally formed, symmetrically arranged protrusions at four positions (top, bottom, front, and back) to form mating grooves. The outer circumferential diameter of the cylindrical body is smaller than the diameter of the reinforcing bar, and the distance between the outer walls of the two symmetrical protrusions is smaller than the diameter of the reinforcing bar. This design ensures that the reinforcing bar assembly with the cap inserted can smoothly pass through channel one and guarantees stable insertion of the cap into each reinforcing bar in the assembly.

[0039] Specific embodiments of the present invention will now be described with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of the invention; however, those skilled in the art will be able to implement the invention without these details.

[0040] As shown in Figures 1 to 10, a rebar bending device includes a base 1 with a worktable 10. A turntable 2 is rotatably mounted on the worktable 10. A servo motor (not shown in the figures) is installed inside the base 1 to drive the turntable 2. A central column 21 and an eccentric component 22 are fixedly connected to the upper surface of the turntable 2, forming a channel 20 for vertically stacking multiple rebars a. The eccentric component 22 is a cylinder and is detachably fixed to the upper surface of the turntable 2 by screws or plug-in connections. During use, eccentric components 22 of different diameters can be replaced to adjust the width of the channel 20, making the device suitable for rebars a of different diameters. Similarly, the central column 21 of different diameters can also be replaced.

[0041] As shown in Figures 1 to 10, a limiting plate 5 is fixedly installed on the right side of the channel 20 on the worktable 10. Five strip-shaped guide grooves 51 are vertically arranged on the front face of the limiting plate 5 to abut against the side wall of the reinforcing bar a, and the strip-shaped guide grooves 51 are aligned with the channel 20. Specifically, the limiting plate 5 is a steel plate, detachably fixed to the worktable 10 by screws. The limiting plate 5 limits the movement of the reinforcing bar a, causing the eccentric component 22 to rotate with the turntable 2, thus cooperating with the central column 21 to achieve cold bending of the reinforcing bar a. The number of strip-shaped guide grooves 51 includes, but is not limited to, five, and can be set according to the power of the servo motor, ensuring that the servo motor can smoothly bend multiple reinforcing bars a without overloading due to an excessive number of reinforcing bars a. Furthermore, the bending angle of the reinforcing bar a is determined by the rotation angle of the eccentric component 22 with the turntable 2. The length and position of the bent section of the reinforcing bar a are usually controlled by marking the surface of the reinforcing bar a beforehand, which is existing technology and will not be elaborated here.

[0042] As shown in Figures 1 to 10, a binding device 3 is also provided between the limiting plate and the channel 20 on the workbench 10. The binding device 3 includes a material trough 31, a movable plate 32, and a cap 4. The material trough 31 is used to vertically place at least one cap 4, and the bottom of the material trough 31 is provided with a discharge port 310.

[0043] In one specific embodiment, the lower end of the feed trough 31 is provided with a right extension plate 311, which is detachably fixed to the front end of the limiting plate 5 by means of screws or the like.

[0044] As shown in Figures 1 to 10, the bottom of the material trough 31 is movably provided with a movable plate 32 for opening and closing the discharge port 310, and the front right side of the movable plate 32 is provided with a receiving groove 33 for connecting to the discharge port 310.

[0045] As shown in Figures 1 to 10, in one specific embodiment, the receiving groove 33 includes a back plate 331, a rear limiting strip 332, and a front limiting strip 333. The movable plate 32 has a material discharge port 320 on its front right side. Below the material discharge port 32, the movable plate 32 has a back plate 331 fixed for fitting the left end of the cap 4. The rear end of the back plate 331 is integrally formed with the rear limiting strip 332, and the front end of the back plate 331 is rotatably and openably provided with the front limiting strip 333. The lower ends of the rear limiting strip 332 and the front limiting strip 333 are symmetrically provided with limiting protrusions 330 for supporting the cap 4.

[0046] Preferably, to reinforce the material trough 31, a reinforcing plate 34 is provided between the back plate 331 and the movable plate 32. The reinforcing plate 34 may include, but is not limited to, a triangular plate. Preferably, the movable plate 32, the back plate 331, and the reinforcing plate 34 are integrally formed metal plates.

[0047] As shown in Figures 1 to 10, the binding device 3 is also equipped with a drive mechanism for moving the movable plate 32. The drive mechanism includes, but is not limited to, an electric telescopic rod 35. A left extension plate 311 is integrally formed at the lower end of the material trough 31. A connecting ear 3311 is integrally formed or welded to the left end of the back plate 331. The electric telescopic rod 35 is fixed to the left extension plate 311 in a front-back orientation by screws or welding, and the telescopic end 351 of the electric telescopic rod 35 is fixedly connected to the connecting ear 3311.

[0048] As shown in Figures 1 to 10, in one specific embodiment, the upper surface of the movable plate 32 is provided with an integrally formed slide rail 321, and the movable plate 32 is movably disposed at the bottom of the material trough 31 via the slide rail 321. Of course, the movable plate 32 can also be assembled at the bottom of the material trough 31 by a linear sliding mechanism such as a ball bearing guide assembly, and no further restrictions are imposed here.

[0049] As shown in Figures 1 to 10, the right end of the cap 4 has multiple vertically arranged butt grooves 40 for inserting reinforcing bars a. In one specific embodiment, the cap 4 includes a plastic shell 41 and multiple magnet blocks 42. The plastic shell 41 has multiple cylindrical bodies 411 arranged vertically. Each cylindrical body 41 has integrally formed, symmetrically arranged protrusions 412 for forming the butt grooves 40 at four positions (top, bottom, front, and back). The end face of the protrusion 412 facing the center of the cylindrical body is a concave curved surface for fitting against the sidewall of the reinforcing bar a. Two adjacent protrusions 412 are connected to each other to strengthen the butt grooves 40.

[0050] More importantly, the outer circumferential diameter d1 of the cylindrical body 411 must be smaller than the diameter d2 of the reinforcing bar a, and the distance L1 between the outer side walls of the two symmetrical protrusions 412 must be smaller than the diameter d2 of the reinforcing bar a. This ensures that the outer contour of the entire cap 4 in the left-right direction is within the projection area of ​​the outer contour of the reinforcing bar a, ensuring that the reinforcing bar a with the cap 4 installed at the end can pass smoothly through the channel 20, and ensuring the stable insertion of the cap 4 and multiple reinforcing bars a.

[0051] As shown in Figures 1 to 10, in one specific embodiment, each cylindrical body 411 is fixedly embedded with a magnet block 42 by means of gluing or snap-fitting. The magnet block 42 is used to attract the reinforcing bar a, thereby reinforcing the connection between the caps 4 and the caps 4. Preferably, the end face of the magnet block 42 facing the reinforcing bar a is higher than that of the cylindrical body 411, ensuring that the magnet block 42 is in contact with the reinforcing bar a and facilitating the replacement of the magnet block 42.

[0052] As shown in Figures 1 to 10, the center-to-center distance L2 between two adjacent cylindrical bodies 411 is greater than the diameter of the reinforcing bar a, so that multiple reinforcing bars a can be arranged in a compact manner. For a more compact arrangement, the center-to-center distance L2 between two adjacent cylindrical bodies 411 is less than 1.2 times the diameter of the reinforcing bar a.

[0053] As shown in Figures 1 to 10, in one specific embodiment, the upper and lower ends of the front limit bar 333 are rotatably connected to the front end of the back plate 331 via a damping pivot 36. Alternatively, the front limit bar 333 can also be rotatably connected to the front end of the back plate 331 via a pin and torsion spring.

[0054] As shown in Figures 1 to 10, in one specific embodiment, the worktable 10 is rotatably provided with at least one driven guide wheel at the front end of the limiting plate 5, and the driven guide wheel is used in conjunction with the limiting plate 5 to better stabilize the reinforcing bar a.

[0055] As shown in Figures 1 to 10, a correction device 6 is also provided on the right side of the limiting plate 5 on the worktable 10. The correction device 6 includes a driving wheel 61 and driven wheels 62. One driving wheel 61 and two driven wheels 62 are rotatably mounted on the worktable 10. A servo motor (not shown in the figure) for driving the driving wheel 61 is installed inside the base 1. The driven wheels 61 are arranged in a triangular pattern, and the two driven wheels 62 and the driving wheel 61 are aligned in a straight line, forming a channel 2 60. Furthermore, channel 2 60 is collinear with the strip guide groove 51.

[0056] As shown in Figures 1 to 10, in one specific embodiment, both the driven wheel 62 and the driving wheel 61 are vertically arranged with multiple annular grooves for fitting against the side wall of the reinforcing bar a.

[0057] This invention also discloses a method for cold bending of reinforcing bars, wherein reinforcing bar a is cold bent using any of the above-described reinforcing bar bending equipment as follows:

[0058] (1) Arrange multiple steel bars a vertically into a steel bar group, and feed the left end of the steel bar group into the channel 2 60 from the right side of the straightening device 6. The steel bar group is driven to move to the left by the driving wheel 61, and the bent steel bar a is straightened by the driving wheel 61 and the two driven wheels 62.

[0059] (2) The active wheel 61 drives the steel bar group to move to the left, so that the left end of the steel bar group enters the strip guide groove 51 of the limiting plate 5; at the same time, the movable plate 32 of the binding device 3 moves forward, so that the cap 4 inside the receiving groove 33 is between the channel 20 and the strip guide groove 51.

[0060] (3) The drive wheel 61 drives the steel bar group to move to the left, so that the left end of the steel bar group is inserted into the cap 4 inside the receiving groove 33. The cap 4 is used to align and fix each steel bar a in the steel bar group, and then the drive wheel 61 is paused.

[0061] (4) Move the movable plate 32 of the binding device 3 backward, and open the front limit bar 333 by relying on the cap 4, so that the cap 4 is separated from the receiving groove 33; continue to move the movable plate 32 of the binding device 3 backward, so that the material drop port 320 is located directly below the material outlet 310, and the cap in the material groove 31 automatically falls into the receiving groove 33 under the action of gravity.

[0062] (5) The active wheel 61 drives the steel bar group to move to the left, so that the left end of the steel bar group enters the channel one; when the left end of the steel bar group reaches the predetermined position, the turntable is rotated counterclockwise, and the steel bar group is bent by the eccentric part.

[0063] Furthermore, it also includes the following steps:

[0064] (6) Repeat steps (1)-(5) to bend multiple steel bars a into steel bar hoops; if the right end of the steel bar group has already detached from the straightening device 6 during the last cold bend, the steel bar group needs to be manually moved to the left. Of course, the driven guide wheel can also be changed to an active guide wheel to provide the power for the steel bar group to move to the left when the right end of the steel bar group detaches from the straightening device 6.

[0065] (7) Remove the steel bar assembly from the equipment and manually attach another cap to the right end of the steel bar assembly.

[0066] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
