Description

Technical Field

[0001] This utility model relates to the field of steel bar processing, and in particular to an automatic bending machine. Background Technology

[0002] Rebar processing machinery is used to process coiled and straight reinforcing bars into the lengths, bends, or assembly components required for reinforcing steel engineering installations. It mainly includes equipment for strengthening, straightening, bending, cutting, bending, component forming, and rebar splicing. Rebar assemblies include reinforcing cages, reinforcing trusses (such as triangular beams, wall panels, columns, and beams), and reinforcing mesh. During the rebar processing, bending machines are sometimes used to bend the reinforcing bars.

[0003] In the existing Chinese utility model publication CN220028492U, a rebar bending machine is disclosed, including a workbench. A first fixed plate is fixedly installed on the top surface of the workbench. A circular through hole is opened on one side of the first fixed plate. A hydraulic cylinder is fixedly sleeved on the inner wall of the circular through hole. A bending assembly is disposed at one end of the telescopic shaft of the hydraulic cylinder and is used to bend the rebar. The bending assembly includes a first moving plate, which is fixedly installed at one end of the telescopic shaft of the second fixed plate. A limiting groove is opened on the top surface of the first moving plate. Through the coordinated use of the workbench, the first fixed plate, the first support plate, the hydraulic cylinder, the first moving plate, the limiting groove, the first threaded hole, the fixed column, the threaded column, and the placement groove, the bending effect of the rebar can be achieved, and the bent rebar can be restored, avoiding the waste of excessively bent rebar.

[0004] Referring to the aforementioned rebar bending machine, it can only bend one rebar at a time, resulting in low bending efficiency. This is particularly problematic during construction when a large number of rebars need bending, as the low efficiency can severely impact project progress. Therefore, improving the efficiency of bending multiple rebars simultaneously is a crucial issue that needs to be addressed in the design of automatic bending machines. Utility Model Content

[0005] This invention provides an automatic bending machine to solve the problem of simultaneously bending multiple steel bars and improving the efficiency of steel bar bending.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides an automatic bending machine, including a support platform, and further comprising:

[0008] A rotating bending structure is mounted on a support platform;

[0009] A fixed structure is provided on the rotating bending structure and the support platform;

[0010] A limiting structure is provided on a fixed structure, and the limiting structure restricts the rotation of the fixed structure.

[0011] Preferably, two support plates are fixedly connected to the bottom side wall of the support platform, and a support frame is fixedly connected to the side wall of the support platform.

[0012] In this technical solution, the support plate supports a pair of support platforms.

[0013] Preferably, the rotating bending structure includes a support rod, a rotating circular plate, a rotating motor, and a rotating rod. The support rod is fixedly connected to the side wall of the support frame, and the rotating rod is rotatably connected between the support frames. The rotating rod passes through the side wall of the support platform, and two rotating circular plates are fixedly connected to the side wall of the rotating rod. The rotating circular plates are located between the support rod and the support platform. The rotating motor is fixedly connected to the side wall of the support rod, and the rotating end of the rotating motor is fixedly connected to the rotating rod.

[0014] In this technical solution, the rotation of the motor drives the rotation of the rotating rod, which in turn drives the rotation of the rotating circular plate, which in turn drives the rotation of the support plate.

[0015] Preferably, angle scale lines are engraved on the sidewalls of the two rotating circular plates.

[0016] In this technical solution, the angle of rotation can be observed by rotating the angle scale line on the circular plate, thereby determining the angle of the steel bar bending.

[0017] Preferably, a support plate is fixedly connected between the two rotating circular plates.

[0018] Preferably, the end of the support platform located between the two rotating circular plates is configured as an arc-shaped structure.

[0019] In this technical solution, steel bars of different thicknesses can be bent downwards along the arc-shaped sidewall of the support platform.

[0020] Preferably, the fixing structure includes an electric push rod, a lifting plate, a fixing block, a sliding sleeve, a sliding rod, and a spring. The electric push rod is fixedly connected to the top side wall of the support plate. The top of the electric push rod is fixedly connected to the lifting plate. Sliding sleeves are fixedly connected at equal intervals on the bottom side wall of the lifting plate. The sliding sleeves are slidably connected to the side wall of the support plate. A sliding rod is slidably connected inside the sliding sleeve. The bottom of the sliding rod is fixedly connected to the fixing block. A spring is fixedly connected between the fixing block and the support plate.

[0021] In this technical solution, the electric push rod shortens to drive the lifting plate to descend, the lifting plate drives the sliding sleeve to descend, the sliding sleeve drives the sliding rod to descend, and the sliding rod drives the fixed block to descend, so that the fixed block abuts against the steel bar. As the lifting plate continues to descend, the sliding rod slides into the sliding sleeve, and the spring is compressed. Depending on the thickness of the steel bar, the degree to which the sliding rod slides into the sliding sleeve varies.

[0022] Preferably, the fixing structure includes a threaded rod, a threaded sleeve, a limiting block, and a rubber pad. The threaded rod is fixedly connected to the top side wall of the fixing block. The threaded sleeve is threadedly connected to the threaded rod. The threaded sleeve and the support plate are slidably connected. The limiting block is fixedly connected to the top of the threaded sleeve. The limiting block is rotatably connected to the side wall of the lifting plate at equal distances. The rubber pad is fixedly connected to the top of the limiting block.

[0023] In this technical solution, the lifting plate drives the threaded sleeve to descend, the threaded sleeve drives the threaded rod to descend, and the threaded rod drives the fixed block to descend, so that the fixed block abuts against the reinforcing bar. As the lifting plate continues to descend, the threaded rod moves into the threaded sleeve, and the threaded sleeve rotates as the threaded rod moves. Depending on the thickness of the reinforcing bar, the degree to which the threaded rod moves into the threaded sleeve varies.

[0024] Preferably, the limiting structure includes a fixed frame, a second electric push rod, a push plate, and a stop block. The fixed frame is fixedly connected to the top side wall of the lifting plate. The second electric push rod is fixedly connected at equal intervals on the top inner side wall of the fixed frame. The push plate is fixedly connected to the bottom of the second electric push rod. The stop block is fixedly connected at equal intervals to the bottom of the push plate.

[0025] In this technical solution, the electric push rod extends to push the push plate down, and the push plate pushes the clamping block down, so that the clamping block presses tightly on the rubber pad, causing the rubber block to sink downward, and restricting the rotation of the rubber pad by the clamping block.

[0026] Preferably, the position of the abutting block corresponds to the position of the rubber pad, and the abutting block has a triangular prism structure.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. The electric push rod shortens, causing the fixing block to descend and press against the reinforcing bar. As the lifting plate continues to descend, the sliding rod slides into the sliding sleeve, compressing the spring and moving the threaded rod into the threaded sleeve. Depending on the thickness of the reinforcing bar, the degree to which the sliding rod slides into the sliding sleeve and the threaded rod moves into the threaded sleeve varies. The electric push rod extends, pushing the clamping block downward, causing the clamping block to press tightly against the rubber pad. The clamping block restricts the rotation of the rubber pad, thus restricting the threaded rod and the fixing block. This allows the fixing block to press tightly against reinforcing bars of different thicknesses, simultaneously fixing reinforcing bars of different thicknesses.

[0030] 2. The rotating motor drives the rotating circular plate to rotate, which in turn drives the fixed structure to rotate. During the rotation, the fixed block presses down the steel bars of different thicknesses, causing them to bend downwards along the arc-shaped side wall of the support platform. The angle of rotation can be observed through the angle scale on the rotating circular plate, thus determining the bending angle of the steel bars. This facilitates the simultaneous bending of steel bars of different thicknesses and improves the efficiency of steel bar bending. Attached Figure Description

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0038] like Figure 1-4 As shown, an automatic bending machine includes a support platform 1, and further includes:

[0039] Rotary bending structure 3, which is mounted on support platform 1;

[0040] Fixed structure 4 is provided on the rotating bending structure 3 and the support platform 1;

[0041] A limiting structure 7 is provided on the fixed structure 4, and the limiting structure 7 restricts the rotation of the fixed structure 4.

[0042] Two support plates 2 are fixedly connected to the bottom side wall of the support platform 1, and a support frame 6 is fixedly connected to the side wall of the support platform 1.

[0043] Support plate 2 supports support platform 1.

[0044] The rotating bending structure 3 includes a support rod 301, a rotating circular plate 302, a rotating motor 303, and a rotating rod 304. The support rod 301 is fixedly connected to the side wall of the support frame 6. The rotating rod 304 is rotatably connected between the support frames 6. The rotating rod 304 passes through the side wall of the support platform 1. Two rotating circular plates 302 are fixedly connected to the side wall of the rotating rod 304. The rotating circular plates 302 are located between the support rod 301 and the support platform 1. The rotating motor 303 is fixedly connected to the side wall of the support rod 301. The rotating end of the rotating motor 303 is fixedly connected to the rotating rod 304.

[0045] The rotating motor 303 rotates, causing the rotating rod 304 to rotate, which in turn causes the rotating circular plate 302 to rotate, and the rotating circular plate 302 causes the support plate 2 5 to rotate.

[0046] Angle scale lines are engraved on the side walls of the two rotating circular plates 302.

[0047] By rotating the angle scale on the circular plate 302, the angle of rotation can be observed, thereby determining the angle of the steel bar bending.

[0048] A support plate 2 5 is fixedly connected between the two rotating circular plates 302.

[0049] The end of the support platform 1 located between the two rotating circular plates 302 is configured as an arc-shaped structure.

[0050] Steel bars of different thicknesses can be bent downwards along the arc-shaped sidewall of support platform 1.

[0051] The fixed structure 4 includes an electric push rod 401, a lifting plate 402, a fixing block 403, a sliding sleeve 404, a sliding rod 405, and a spring 406. The electric push rod 401 is fixedly connected to the top side wall of the support plate 5. The top of the electric push rod 401 is fixedly connected to the lifting plate 402. Sliding sleeves 404 are fixedly connected at equal intervals on the bottom side wall of the lifting plate 402. The sliding sleeves 404 are slidably connected to the side wall of the support plate 5. The sliding rod 405 is slidably connected inside the sliding sleeve 404. The bottom of the sliding rod 405 is fixedly connected to the fixing block 403. The spring 406 is fixedly connected between the fixing block 403 and the support plate 5.

[0052] The electric push rod 401 shortens, causing the lifting plate 402 to descend. The lifting plate 402 causes the sliding sleeve 404 to descend, which in turn causes the sliding rod 405 to descend. The sliding rod 405 causes the fixing block 403 to descend, so that the fixing block 403 abuts against the steel bar. As the lifting plate 402 continues to descend, the sliding rod 405 slides into the sliding sleeve 404, and the spring 406 is compressed. Depending on the thickness of the steel bar, the degree to which the sliding rod 405 slides into the sliding sleeve 404 varies.

[0053] The fixing structure 4 includes a threaded rod 411, a threaded sleeve 412, a limiting block 413, and a rubber pad 414. The threaded rod 411 is fixedly connected to the top side wall of the fixing block 403. The threaded sleeve 412 is threadedly connected to the threaded rod 411. The threaded sleeve 412 is slidably connected to the support plate 5. The limiting block 413 is fixedly connected to the top of the threaded sleeve 412. The limiting block 413 is rotatably connected to the side wall of the lifting plate 402 at equal distances. The rubber pad 414 is fixedly connected to the top of the limiting block 413.

[0054] The lifting plate 402 causes the threaded sleeve 412 to descend, the threaded sleeve 412 causes the threaded rod 411 to descend, and the threaded rod 411 causes the fixing block 403 to descend, so that the fixing block 403 abuts against the reinforcing bar. As the lifting plate 402 continues to descend, the threaded rod 411 moves into the threaded sleeve 412, and the threaded sleeve 412 rotates as the threaded rod 411 moves. Depending on the thickness of the reinforcing bar, the degree to which the threaded rod 411 moves into the threaded sleeve 412 varies.

[0055] The limiting structure 7 includes a fixed frame 701, an electric push rod 702, a push plate 703, and a stop block 703. The fixed frame 701 is fixedly connected to the top side wall of the lifting plate 402. The electric push rod 702 is fixedly connected at equal intervals on the top inner side wall of the fixed frame 701. The push plate 703 is fixedly connected to the bottom of the electric push rod 702. The stop block 703 is fixedly connected to the bottom of the push plate 703 at equal intervals.

[0056] The electric push rod 702 extends to push the push plate 703 down, and the push plate 703 pushes the clamping block 703 down, so that the clamping block 703 presses tightly on the rubber pad 414, causing the rubber block to sink downward, and restricting the rotation of the rubber pad 414 by the clamping block 703.

[0057] The position of the abutting block 703 corresponds to the position of the rubber pad 414, and the abutting block 703 has a triangular prism structure.

[0058] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. Steel bars of different thicknesses that need to be bent at the same angle are placed on the top side wall of the support platform 1 below the fixing block 403. The electric push rod 401 is activated, shortening it and causing the lifting plate 402 to descend. The lifting plate 402 then causes the sliding sleeve 404 and the threaded sleeve 412 to descend. The sliding sleeve 404 causes the sliding rod 405 to descend, and the threaded sleeve 412 causes the threaded rod 411 to descend. The sliding rod 405 and the threaded rod 411 drive the fixed block 403 to descend, so that the fixed block 403 abuts against the steel bar. As the lifting plate 402 continues to descend, the sliding rod 405 slides into the sliding sleeve 404, the spring 406 is compressed, and the threaded rod 411 moves into the threaded sleeve 412. The threaded sleeve 412 rotates as the threaded rod 411 moves. Depending on the thickness of the steel bar, the degree to which the sliding rod 405 slides into the sliding sleeve 404 and the threaded rod 411 moves into the threaded sleeve 412 varies.

[0059] Re-activate the electric push rod 702. The electric push rod 702 extends and pushes the push plate 703 down. The push plate 703 pushes the clamping block 703 down, so that the clamping block 703 presses tightly on the rubber pad 414, causing the rubber block to sink downward. The clamping block 703 restricts the rotation of the rubber pad 414, the rubber pad 414 restricts the rotation of the limiting block, and the limiting block restricts the rotation of the threaded sleeve 412, so that the threaded rod 411 is restricted, thereby restricting the fixing block 403. This makes it easier for the fixing block 403 to press tightly against the steel bars of different thicknesses, and to fix the steel bars of different thicknesses simultaneously.

[0060] When bending, the rotating motor 303 is started. The rotating motor 303 rotates, which drives the rotating rod 304 to rotate. The rotating rod 304 drives the rotating circular plate 302 to rotate. The rotating circular plate 302 drives the support plate 5 to rotate. The support plate 5 drives the fixed structure 4 to rotate. During the rotation, the fixed block 403 presses down the fixed steel bars of different thicknesses, so that the steel bars of different thicknesses are bent down along the arc-shaped side wall of the support platform 1. The angle of rotation can be observed by the angle scale line on the rotating circular plate 302, so as to determine the bending angle of the steel bars, which is convenient for the synchronous bending of steel bars of different thicknesses.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
