Description

Technical Field

[0001] This utility model relates to the field of cold bending testing technology for reinforcing bars, and in particular to a workbench for a cold bending testing machine for reinforcing bars. Background Technology

[0002] The workbench of a cold bending test machine is an important component of cold bending test equipment for reinforcing bars. It is mainly used to place reinforcing bars and provide support and operating platform for bending tests. The workbench is usually equipped with a working plate and a clamping device to fix the reinforcing bars and ensure the accuracy of the bending test. Some workbench are also equipped with adjustable support rollers or pressure heads to adapt to the cold bending requirements of reinforcing bars of different specifications.

[0003] During rebar bending tests, the rebar cold bending testing machine generates a large amount of debris due to plastic deformation and fracture during the bending process. This debris easily accumulates on the worktable surface, in gaps, grooves, and at the connection points with the bending molds. However, because the worktable surface may have a complex structure or be tightly connected to other components, it may lack dedicated cleaning channels or convenient cleaning designs. This makes it difficult to remove the debris quickly and thoroughly. Long-term accumulation not only contaminates the worktable surface but also affects the stability of subsequent rebar placement and the accuracy of testing. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by proposing a workbench for a steel bar cold bending test machine, which enables rapid and efficient cleaning of debris, reduces the impact of debris accumulation on test accuracy and equipment operation, reduces the time and effort required for manual cleaning, and improves the convenience of cleaning and maintenance of the workbench.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a workbench for a rebar cold bending testing machine, comprising a cabinet, a frame, a cylinder, and a cleaning device. The frame is fixed to the upper surface of the cabinet, and the cylinder is fixed to the upper surface of the frame. The cleaning device is located at one end of the frame and includes a motor. The motor is fixedly connected to the frame, and a column is fixedly connected to the drive end of the motor. The end of the column away from the motor is rotatably connected to the frame. A sliding hole is provided on the surface of the frame, and a magnetic suction rod is slidably connected to the inner wall of the sliding hole. A traction belt is fixedly connected to one end of the magnetic suction rod, and the end of the traction belt away from the magnetic suction rod is fixedly connected to the column. By setting up the cleaning device, the magnetic force of the magnetic suction rod can automatically attract the debris generated by bending the rebar. Then, through the motor drive and the cooperation of the scraper, the debris is scraped off into the box, achieving rapid and efficient cleaning of debris, reducing the impact of debris accumulation on testing accuracy and equipment operation, reducing the time and effort of manual cleaning, and improving the convenience of cleaning and maintenance of the workbench.

[0006] Preferably, the magnetic suction rod is U-shaped, and a through hole is provided at the end of the cabinet near the magnetic suction rod. By using the magnetic suction rod, driven by a motor and pulled by a traction belt, it moves forward towards the test area, using its own magnetic force to attract debris generated by the bending of the reinforcing steel bars, thus quickly collecting debris from the workbench surface. Subsequently, during the resetting process, friction with the scraper causes the attracted debris to be scraped off and fall into the box through the through hole, completing the debris collection. This method of efficiently gathering dispersed debris through magnetic attraction solves the problem of inconvenient debris removal and improves the cleaning efficiency of the workbench.

[0007] Preferably, a circular groove is provided on one side of the cabinet, and a hook is inserted into the inner wall of the groove. A box is fixedly connected to the upper surface of the hook, and the box is located below the through hole.

[0008] Preferably, a spring is fixedly connected to one side of the magnetic suction rod, and the end of the spring away from the magnetic suction rod is fixedly connected to the frame; a scraper is fixedly connected to one side of the frame, and the scraper is sleeved on the magnetic suction rod. By setting the spring, when the motor drives the column to rotate in the opposite direction to release the traction belt, the spring loses its restraint and generates elastic force to squeeze the magnetic suction rod, pushing the magnetic suction rod to reset. During the reset process, the magnetic suction rod rubs against the scraper to scrape off and clean the debris, ensuring that the magnetic suction rod can return to its initial position for the next cleaning, and at the same time assisting in completing the reset action of the entire cleaning cycle.

[0009] Preferably, the surface of the frame is provided with a shielding assembly, which includes a main acrylic plate rotatably connected to the frame; a secondary acrylic plate is rotatably connected to one end of the frame near the main acrylic plate. By providing the shielding assembly, the main and secondary acrylic plates can effectively block the splashing of debris during testing without affecting the observation of the experimental process, thus providing safety protection. At the same time, the fixing method of the baffle and the clamp ensures the stability of the shielding, protecting the safety of the operator and reducing debris spillage and environmental pollution.

[0010] Preferably, a stop bar is rotatably connected to the surface of the main acrylic plate, and a retaining sleeve is fixedly connected to the surface of the secondary acrylic plate. By setting the stop bar, it rotates and abuts against the retaining sleeve during testing, thereby fixing the main acrylic plate and the secondary acrylic plate to the frame surface. This ensures that the shielding assembly can stably shield the test area, without affecting the observation of the experimental process through the transparent acrylic plate, and can reliably provide protection when debris splashes, preventing the shielding assembly from loosening and causing protection failure.

[0011] Preferably, the main acrylic plate and the secondary acrylic plate are arranged symmetrically, and the stop bar is engaged with the retaining sleeve.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention features a cleaning device that uses the magnetic force of a magnetic rod to automatically attract debris generated by bending steel bars. Then, a motor-driven scraper scrapes the debris into a box, achieving rapid and efficient cleaning of debris. This reduces the impact of debris accumulation on testing accuracy and equipment operation, reduces the time and effort required for manual cleaning, and improves the convenience of cleaning and maintaining the workbench.

[0013] This invention, by setting up a shielding component, can effectively block the splashing of debris during testing without affecting the observation of the experimental process, thus playing a safety protection role. At the same time, the fixing method of the baffle and the sleeve ensures the stability of the shielding, which not only protects the safety of the operator, but also reduces the pollution of the environment by debris spillage.

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

[0017] Please see Figures 1-5 A workbench for a cold bending test machine for reinforcing bars includes a cabinet 1, a frame 2, a cylinder 3, and a cleaning device 4. The frame 2 is fixed to the upper surface of the cabinet 1, the cylinder 3 is fixed to the upper surface of the frame 2, a pressure rod 6 is fixedly connected to the drive end of the cylinder 3, and a clamp 5 is fixedly connected to the upper surface of the cabinet 1.

[0018] The cleaning device 4 is located at one end of the frame 2. The cleaning device 4 includes a motor 43, which is fixedly connected to the frame 2. A column 44 is fixedly connected to the drive end of the motor 43, and the end of the column 44 away from the motor 43 is rotatably connected to the frame 2. A sliding hole is formed on the surface of the frame 2, and a magnetic suction rod 42 is slidably connected to the inner wall of the sliding hole. A traction belt 46 is fixedly connected to one end of the magnetic suction rod 42, and the end of the traction belt 46 away from the magnetic suction rod 42 is fixedly connected to the column 44. By setting up the cleaning device 4, the magnetic force of the magnetic suction rod 42 can automatically attract debris generated by bending the reinforcing steel. Then, driven by the motor 43 and cooperating with the scraper 41, the debris is scraped off into the box 48, achieving rapid and efficient cleaning of debris. This reduces the impact of debris accumulation on testing accuracy and equipment operation, reduces the time and effort required for manual cleaning, and improves the convenience of cleaning and maintaining the workbench.

[0019] Specifically, the magnetic suction rod 42 is U-shaped, and a through hole 410 is provided at the end of the cabinet 1 closest to the magnetic suction rod 42. Driven by the motor 43 and pulled by the traction belt 46, the magnetic suction rod 42 moves forward towards the testing area, using its own magnetic force to attract debris generated by the bending of the reinforcing steel bars, thus quickly collecting debris from the workbench surface. During the resetting process, it rubs against the scraper 41, causing the attracted debris to be scraped off and fall into the box 48 through the through hole 410, completing the debris collection. This method of magnetic attraction efficiently gathers dispersed debris, solving the problem of inconvenient debris removal and improving the cleaning efficiency of the workbench.

[0020] Specifically, a circular groove is provided on one side of the cabinet 1, and a hook 49 is inserted into the inner wall of the circular groove. A box 48 is fixedly connected to the upper surface of the hook 49, and the box 48 is located below the through hole 410.

[0021] Specifically, a spring 47 is fixedly connected to one side of the magnetic suction rod 42, and the end of the spring 47 away from the magnetic suction rod 42 is fixedly connected to the frame 2; a scraper 41 is fixedly connected to one side of the frame 2, and the scraper 41 is sleeved with the magnetic suction rod 42. By setting the spring 47, when the motor 43 drives the column 44 to rotate in the opposite direction to release the traction belt 46, the spring 47 loses its restraint and generates elastic force to squeeze the magnetic suction rod 42, pushing the magnetic suction rod 42 to reset. During the reset process, the magnetic suction rod 42 rubs against the scraper 41 to scrape off and clean the debris, ensuring that the magnetic suction rod 42 can return to its initial position for the next cleaning, and at the same time assisting in completing the reset action of the entire cleaning cycle.

[0022] Specifically, a shielding assembly 45 is provided on the surface of frame 2. The shielding assembly 45 includes a main acrylic plate 451, which is rotatably connected to frame 2. A secondary acrylic plate 452 is rotatably connected to one end of frame 2 near the main acrylic plate 451. By setting up the shielding assembly 45, the main and secondary acrylic plates 452 can effectively block the splashing of debris during the test without affecting the observation of the experimental process, thus playing a safety protection role. At the same time, the fixing method of the baffle 453 and the clamp 454 ensures the stability of the shielding, which not only ensures the safety of the operator but also reduces the spillage of debris and environmental pollution.

[0023] Specifically, a stop bar 453 is rotatably connected to the surface of the main acrylic plate 451, and a retaining sleeve 454 is fixedly connected to the surface of the secondary acrylic plate 452. By setting the stop bar 453, it rotates and abuts against the retaining sleeve 454 during testing, thereby fixing the main acrylic plate 451 and the secondary acrylic plate 452 to the surface of the frame 2. This ensures that the shielding assembly 45 can stably shield the test area, without affecting the observation of the experimental process through the transparent acrylic plate, and can reliably play a protective role when debris splashes, preventing the shielding assembly 45 from loosening and causing the protection to fail.

[0024] Specifically, the main acrylic plate 451 and the secondary acrylic plate 452 are symmetrically arranged, and the stop bar 453 is engaged with the sleeve 454.

[0025] The working principle of this utility model is as follows: By setting up the cleaning device 4, when the surface of the cabinet 1 needs to be cleaned after the test, the motor 43 is started. The motor 43 drives the column 44 to rotate. While the column 44 is rotating, the traction belt 46 is wound up. As the traction belt 46 is continuously wound up, the magnetic suction rod 42 moves forward and approaches the test area. Under the action of magnetic force, the debris is attracted to the surface of the magnetic suction rod 42. Then the motor 43 drives the column 44 to rotate in the opposite direction. The spring 47 is released and squeezes the magnetic suction rod 42 to reset. When the magnetic suction rod 42 resets, it rubs against the scraper 41. The scraper 41 scrapes off the debris on the surface of the magnetic suction rod 42 and drops it into the through hole 410. After passing through the through hole 410, it falls into the box 48, completing the cleaning.

[0026] By setting the shielding component 45, during the test, the main and secondary acrylic plates shield the surface of the frame 2, and the rotating stop bar 453 abuts against the clamp 454 to fix the acrylic plates. Since the acrylic plates are transparent, the entire experimental process can be seen, and at the same time, it can provide effective protection when debris is splashed.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
