Description

Technical Field

[0001] This utility model relates to the field of stadium construction technology, specifically to a steel bar cutting device. Background Technology

[0002] Sports stadiums are professional venues for sports training, competitions, and physical exercise. Foundation construction is a crucial stage in the construction of large-space structures like stadiums. It requires work such as foundation excavation, rebar tying, formwork erection, and concrete pouring, all based on geological survey reports and design requirements. The quality of foundation construction directly affects the stability and safety of the entire stadium and other large-space buildings. Therefore, rebar cutting equipment is necessary to cut the rebar during stadium construction.

[0003] Patent publication number CN218080172U discloses a steel bar processing device for stadium construction, including a cutting machine body and a conveying table fixedly connected to the cutting machine body. The cutting machine body is provided with a feeding section and a discharging section. Two cutting blades are slidably arranged on the cutting machine body, and both cutting blades are located between the feeding section and the discharging section. The cutting machine body is provided with a first driving component that drives the two cutting blades to slide in a direction that moves closer to or further away from each other.

[0004] To address the issue of workers needing to hold the rebar securely during rebar cutting, resulting in high labor intensity, existing technology uses a drive mechanism to press a sliding plate against one end of the rebar. The drive mechanism then moves the sliding plate a certain distance, bringing the rebar between the two cutters. The rebar is then clamped by a clamping mechanism, and the first drive component inside the cutting machine moves the two cutters closer together to cut the rebar. However, this method still suffers from the problem of the device being unable to determine the rebar cutting position and length in a timely manner, leading to low cutting accuracy and ultimately poor device performance. Utility Model Content

[0005] The purpose of this invention is to provide a rebar cutting device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A rebar cutting device includes a base, a cutting opening on the right side of the top surface of the base, a measuring mechanism on the left side of the base, a feeding mechanism in the middle of the top surface of the base, and a cutting mechanism on the right side of the top surface of the base.

[0008] The measuring mechanism includes a slide, a scale, and a limiting plate. The slide is located on the left side of the base. An elastic element is fixedly connected to the side of the slide. One end of the elastic element is fixedly connected to the surface of the limiting plate. Pointers are fixedly connected to both sides of the limiting plate.

[0009] A further improvement of this utility model is that: the scale is fixedly connected to the top surface of the base, one end of the pointer is slidably connected to the surface of the scale, a moving strip is fixedly connected to the side of the limiting plate, and one end of the moving strip is movably sleeved inside the base.

[0010] A further improvement of the present invention is that the feeding mechanism includes a fixed plate fixedly connected to the middle of the top surface of the base, a bracket fixedly connected to one side of the top surface of the fixed plate, a stepper motor fixedly connected to the top surface of the bracket, and the output shaft of the stepper motor extending to the bottom of the bracket and fixedly connected to a positioning wheel.

[0011] A further improvement of the present invention is that: a screw block is fixedly connected to the side of the fixing plate, a screw rod is threadedly connected to the inside of the screw block, one end of the screw rod extends to the top of the fixing plate and is rotatably connected to a fixing frame, and a movable wheel is rotatably connected to the top surface of the fixing frame via a rotating shaft.

[0012] A further improvement of this utility model is that a straight rod is fixedly connected to the side of the fixing frame, one end of the straight rod passes through the screw block, and the straight rod is movably connected to the screw block.

[0013] A further improvement of this utility model is that: the cutting mechanism includes a cutting frame fixedly connected to the right side of the top surface of the base; a hydraulic rod is fixedly connected to the middle of the top surface of the cutting frame; the telescopic end of the hydraulic rod extends to the bottom of the cutting frame and is fixedly connected to a connecting block; a drive motor is fixedly connected to the side of the connecting block; a cutting blade is fixedly connected to the output shaft of the drive motor; the cutting blade and the cutting opening are on the same vertical plane; a curved rod is fixedly connected to the side of the connecting block and above the drive motor; and a cleaning component is fixedly connected to one end of the curved rod.

[0014] A further improvement of the present invention is that the cleaning assembly includes a cleaning frame fixedly connected to one end of the crank, the cleaning frame being sleeved on the outside of the cutting blade, a cleaning brush being fixedly connected to the middle of the inner side of the cleaning frame, and scrapers being fixedly connected to both ends of the inner side of the cleaning frame.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a rebar cutting device, which employs a measuring mechanism, a limiting plate, a pointer, a scale value, an elastic element, a moving strip, a slide groove, and a cutting opening. By pulling the limiting plate, the movement of the limiting plate causes the elastic element to stretch and generate elastic force, aligning one end of the rebar with the cutting opening, while the other end is pressed against the side of the limiting plate. When the feeding mechanism moves the rebar, the elastic element restores its elastic force, causing the limiting plate to spring back and remain pressed against one end of the rebar. As the limiting plate springs back, it causes the pointer to move. By using the initial position of the pointer and the scale value position it has moved to, the feed length of the rebar can be determined, thereby determining the cutting length of the rebar, improving the accuracy and precision of the cutting.

[0017] 2. This utility model provides a rebar cutting device, which employs a feeding mechanism, a fixed plate, a bracket, a positioning wheel, a stepper motor, a screw block, a screw rod, a straight rod, a fixed frame, and a moving wheel. By placing the rebar on the side of the positioning wheel and rotating the screw rod, the screw rod and the screw block engage threadedly, driving the fixed frame to move. The fixed frame then drives the moving wheel to move, and the positioning wheel clamps and limits the rebar. The straight rod ensures the smooth movement of the fixed frame. The stepper motor drives the positioning wheel to rotate, and the friction between the positioning wheel and the rebar drives the rebar to move, realizing the feeding and cutting of the rebar. It eliminates the need for manual holding of the rebar, improves cutting efficiency, and can adapt to rebars of different thicknesses, making it more adaptable.

[0018] 3. This utility model provides a rebar cutting device, which adopts the cooperation of a cutting mechanism, a cutting frame, a hydraulic rod, a connecting block, a drive motor, a cutting blade, a curved rod, a cleaning component, a cleaning frame, a scraper, and a cleaning brush. The drive motor drives the cutting blade to rotate, the hydraulic rod extends and drives the connecting block to move down, and the connecting block drives the cutting blade to move down, thereby using the cutting blade to cut the rebar. When the cutting blade rotates, the scraper can scrape off the debris attached to the surface of the cutting blade, and the cleaning brush cleans and removes the debris, ensuring the cutting effect of the cutting blade.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model provides a rebar cutting device, including a base 1. A cutting opening 2 is provided on the right side of the top surface of the base 1. A measuring mechanism 3 is provided on the left side of the base 1. A feeding mechanism 4 is provided in the middle of the top surface of the base 1. A cutting mechanism 5 is provided on the right side of the top surface of the base 1. The measuring mechanism 3 includes a slide 36, a scale 33, and a limiting plate 31. The slide 36 is located on the left side of the base 1. An elastic element 34 is fixedly connected to the side of the slide 36. One end of the elastic element 34 is fixedly connected to the surface of the limiting plate 31. Pointers 32 are fixedly connected to both sides of the limiting plate 31. The scale 33 is fixedly connected to the top surface of the base 1. One end of the pointer 32 is connected to the surface of the scale 33. The sliding connection is provided. A moving strip 35 is fixedly connected to the side of the limiting plate 31. One end of the moving strip 35 is movably sleeved inside the base 1. By pulling the limiting plate 31, the limiting plate 31 moves and causes the elastic element 34 to stretch and generate elastic force, aligning one end of the steel bar with the cutting opening 2, while the other end is pressed against the side of the limiting plate 31. When the feeding mechanism 4 moves the steel bar, the elastic element 34 restores its elastic force and causes the limiting plate 31 to spring back and always press against one end of the steel bar. When the limiting plate 31 springs back and moves, it causes the pointer 32 to move. Thus, the feed length of the steel bar is determined by the initial position of the pointer 32 and the scale value position on the scale 33 it moves to, thereby determining the cutting length of the steel bar.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the feeding mechanism 4 includes a fixed plate 41 fixedly connected to the middle of the top surface of the base 1. A bracket 42 is fixedly connected to one side of the top surface of the fixed plate 41. A stepper motor 44 is fixedly connected to the top surface of the bracket 42. The output shaft of the stepper motor 44 extends to the lower part of the bracket 42 and is fixedly connected to a positioning wheel 43. A screw block 45 is fixedly connected to the side of the fixed plate 41. A screw rod 46 is threadedly connected to the inside of the screw block 45. One end of the screw rod 46 extends to the top of the fixed plate 41 and is rotatably connected to a fixing frame 48. The top surface of the fixing frame 48 is rotated by a rotating shaft. The fixed frame 48 is connected to a movable rotating wheel 49. A straight rod 47 is fixedly connected to the side of the fixed frame 48. One end of the straight rod 47 passes through a screw block 45. The straight rod 47 and the screw block 45 are movably connected. By placing the steel bar on the side of the positioning rotating wheel 43 and rotating the screw 46, the screw 46 and the screw block 45 are threaded together, which drives the fixed frame 48 to move. The fixed frame 48 drives the movable rotating wheel 49 to move and the positioning rotating wheel 43 to clamp and limit the steel bar. The setting of the straight rod 47 ensures the smooth movement of the fixed frame 48. The positioning rotating wheel 43 is driven to rotate by the stepper motor 44. The friction between the positioning rotating wheel 43 and the steel bar is used to drive the steel bar to move, thereby realizing the feeding and cutting of the steel bar.

[0030] Example 3

[0031] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the cutting mechanism 5 includes a cutting frame 51 fixedly connected to the right side of the top surface of the base 1. A hydraulic rod 52 is fixedly connected to the middle of the top surface of the cutting frame 51. The telescopic end of the hydraulic rod 52 extends to the lower part of the cutting frame 51 and is fixedly connected to a connecting block 53. A drive motor 54 is fixedly connected to the side of the connecting block 53. A cutting blade 55 is fixedly connected to the output shaft of the drive motor 54. The cutting blade 55 and the cutting opening 2 are on the same vertical plane. A curved rod 56 is fixedly connected to the side of the connecting block 53 and above the drive motor 54. A cleaning component 57 is fixedly connected to one end of the curved rod 56. The cleaning assembly 57 includes a cleaning frame 571 fixedly connected to one end of the crank 56. The cleaning frame 571 is sleeved on the outside of the cutting blade 55. A cleaning brush 573 is fixedly connected to the middle of the inner side of the cleaning frame 571. Scrapers 572 are fixedly connected to both ends of the inner side of the cleaning frame 571. The cutting blade 55 is rotated by the drive motor 54. The hydraulic rod 52 extends and drives the connecting block 53 to move down. The connecting block 53 drives the cutting blade 55 to move down, thereby using the cutting blade 55 to cut the steel bar. When the cutting blade 55 rotates, the scraper 572 can scrape off the debris attached to the surface of the cutting blade 55, and the cleaning brush 573 cleans and removes the debris, ensuring the cutting effect of the cutting blade 55.

[0032] The working principle of this rebar cutting device will be explained in detail below.

[0033] like Figure 1-5 As shown, during use, align one end of the rebar with the cut 2, place the rebar on the side of the positioning wheel 43, rotate the screw 46, the screw 46 and the screw block 45 are threaded together, driving the fixing frame 48 to move. The fixing frame 48 drives the moving wheel 49 to move and the positioning wheel 43 clamps and limits the rebar. The other end of the rebar abuts against the side of the limiting plate 31. The stepper motor 44 drives the positioning wheel 43 to rotate. The friction between the positioning wheel 43 and the rebar drives the rebar to move. When the rebar moves, the elastic element 34 restores its elasticity and drives the limiting plate 31 to spring back and always abut against one end of the rebar. When the limiting plate 31 springs back and moves, it drives the pointer 3. 2. The pointer 32 is moved to determine the feed length of the steel bar by using the initial position of the pointer 32 and the scale value position on the scale 33. After reaching the required cutting length, the cutting blade 55 is rotated by the drive motor 54. The hydraulic rod 52 extends and moves the connecting block 53 downward. The connecting block 53 moves the cutting blade 55 downward, thereby cutting the steel bar with the cutting blade 55. When the cutting blade 55 rotates, the scraper 572 can scrape off the debris attached to the surface of the cutting blade 55. The cleaning brush 573 cleans and removes the debris. Then, the stepper motor 44 is started to continue rotating and driving the steel bar to continue to be fed. The cutting is carried out again in the above manner.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
