The former is easy to program but has low efficiency and cannot be adapted to use in construction projects, while the latter can bundle steel bars for batch cutting, but its cutting distance cannot be controlled and loading and unloading are labor-intensive. Therefore, a steel bar cutting device for construction projects is designed. Summary of the Invention

The first reel and the second reel are rotatably connected to the vertical plate through a first rotating shaft and a second rotating shaft, respectively. A motor is provided on the rear side wall of the vertical plate and the motor is fixed to the first rotating shaft. A steel bar is connected between the first reel and the second reel. Hollow slots are provided on both the first reel and the second reel.

[0008] The adjustment mechanism includes a slide groove, which is formed on a vertical plate. A threaded sleeve is fixed on the vertical plate. A bolt is internally threaded onto the threaded sleeve. A sleeve is rotatably connected to the circumferential surface of the first rotating shaft. The bottom of the bolt is rotatably connected to the sleeve via a hinge. Limiting discs are fixed to both the front and rear side walls of the sleeve. The motor is mounted on the limiting disc located on the rear side. A rotating ring is fixed to the upper end of the bolt via multiple fixing rods.

[0009] The distance control mechanism includes a slide rail, on which a sliding sleeve is slidably connected. An infrared detector is fixed on the sliding sleeve, and the infrared detector and the reinforcing bar are on the same horizontal line. The slide rail is provided with distance scale.

[0010] Preferably, the cutting mechanism includes a cylinder, which is fixed to the frame. An upper cutter head is fixed to the lower end of the cylinder. A connecting plate is fixed to the rear side wall of the frame. A lower cutter head is fixed to the top of the connecting plate, and the lower cutter head matches the upper cutter head.

[0011] Preferably, a controller is provided on the top of the frame, and the controller is electrically connected to the cylinder and the infrared detector.

[0017] Preferably, the bolt is threaded with a nut, and the nut is positioned between the threaded sleeve and the swivel.

[0018] Preferably, both the bottom of the upright plate and the frame are fixed with triangular bases.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this solution, the entire rebar cutting equipment has a reasonable structure and ingenious design, changing the common cutting method, reducing noise and increasing efficiency. The semi-automatic setting of the device improves the efficiency of rebar cutting, saves manpower, and allows for controllable cutting distance. It is adaptable to rebars of different sizes and diameters, making it highly practical. This effectively solves the problems of existing rebar cutting equipment, which are mainly portable and bundled batch cutting types. The former is convenient but inefficient and unsuitable for construction projects, while the latter can bundle rebars for batch cutting, but the cutting distance is uncontrollable and loading and unloading are labor-intensive. In this invention, the rebar is first fed through the feeding mechanism in the device, inserted into the gap between the first and second reels. The motor output drives the rotation of the first reel, causing the first reel to rotate. The rebar is driven to the left to engage with the second reel, improving transmission stability. When the rebar sizes are different, the distance between the first and second reels needs to be adjusted. This adjustment can be made through an adjustment mechanism. By manually rotating the swivel, the entire bolt rotates within the threaded sleeve, and the bottom of the bolt rotates through the hinge shaft and the sleeve on the first rotating shaft, causing the entire first reel to rise or fall, thus changing the distance between it and the second reel and completing the adjustment. This adapts to rebars of different sizes. The rebar is driven to the left by the feeding mechanism and continues to be conveyed to the cutting mechanism. When it reaches the infrared detector in the distance control mechanism, the infrared detector detects whether the rebar has reached the designated distance. After the rebar reaches the designated distance, the infrared detector transmits an electrical signal to the controller, which then controls the cutting mechanism to cut the rebar.

[0021] 2. In this solution, during cutting, the upper cutter head is driven downward by a cylinder to intersect with the lower cutter head, cutting the reinforcing steel bar between them. The controller, in conjunction with the cylinder and infrared detector, enhances the automation level of the device and saves manpower. The distance control mechanism, by sliding the sleeve onto the slide rail, controls the distance of the cut reinforcing steel bar. Combined with the scale on the slide rail, this further improves the ease of use. After adjustment, the locking bolt is threaded onto the sleeve by tightening the cap, thus fixing the distance of the sleeve and preventing accidental sliding. The plate effectively restricts the sliding position of the sleeve, preventing derailment. The two limiting grooves enhance the restraint on the reinforcing bars, preventing them from deviating during cutting. The feeding trough and arc-shaped guide plate allow the reinforcing bars to roll outwards after cutting, achieving semi-automatic feeding and saving manpower. Placing the right inner wall of the feeding trough and the left side wall of the lower cutter head on the same plane ensures that the cut reinforcing bars roll out of the feeding trough. The nut enhances the restraint on the adjusted bolt position. The two triangular bases fixed to the vertical plate and the bottom of the frame improve the stability of the entire device.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figure 1 - Figure 5 The present invention provides the following technical solution: a steel bar cutting device for construction engineering includes a frame (16), a cutting mechanism is provided on the frame (16), a distance control mechanism is provided on the left side of the cutting mechanism, a feeding mechanism is provided on the right side of the cutting mechanism, and an adjustment mechanism is provided on the feeding mechanism;

[0032] The feeding mechanism includes a first reel 3 and a second reel 5, which are symmetrically distributed. A vertical plate 1 is provided on the right side of the frame 16. The first reel 3 and the second reel 5 are rotatably connected to the vertical plate 1 through a first rotating shaft 6 and a second rotating shaft 7, respectively. A motor 9 is provided on the rear side wall of the vertical plate 1, and the motor 9 is fixed to the first rotating shaft 6. A steel bar 15 is connected between the first reel 3 and the second reel 5. Hollow slots 4 are provided on both the first reel 3 and the second reel 5.

[0033] The adjustment mechanism includes a slide 2, which is opened on the vertical plate 1. A threaded sleeve 10 is fixed on the vertical plate 1. A bolt 11 is connected to the internal thread of the threaded sleeve 10. The sleeve is rotatably connected to the circumferential surface of the first rotating shaft 6. The bottom of the bolt 11 is rotatably connected to the sleeve through a hinge. Limiting discs 8 are fixed on both the front and rear side walls of the sleeve. The motor 9 is set on the limiting disc 8 located on the rear side. A rotating ring 13 is fixed to the upper end of the bolt 11 through multiple fixing rods.

[0034] The distance control mechanism includes a slide rail 23, a sliding sleeve 24 is slidably connected to the slide rail 23, an infrared detector 25 is fixed on the sliding sleeve 24, and the infrared detector 25 and the steel bar 15 are on the same horizontal line. The slide rail 23 is provided with distance scale.

[0035] In a specific embodiment of the present invention, the entire rebar cutting device has a reasonable structure and ingenious design, changing the common cutting method, reducing noise and increasing efficiency. Simultaneously, the semi-automatic setting of the device improves the efficiency of rebar cutting, saves manpower, and allows for controllable cutting distance. It is adaptable to rebars of different sizes and diameters, making it highly practical. This effectively solves the problems of existing rebar cutting equipment, which are mainly portable and bundled batch cutting types. The former is easy to use but inefficient and unsuitable for construction projects, while the latter can bundle rebars for batch cutting, but its cutting distance is uncontrollable and loading and unloading are labor-intensive. In this invention, the rebar 15 is first fed through the feeding mechanism in the device and inserted into the gap between the first reel 3 and the second reel 5. The output of the motor 9 drives the rotation of the first reel 3, which causes the rebar 15 to rotate to the left. The second reel 5 improves transmission stability. When the size of the reinforcing bar 15 is different, the distance between the first reel 3 and the second reel 5 needs to be adjusted. The adjustment can be made through the adjustment mechanism. By manually rotating the rotating ring 13, the entire bolt 11 is driven to rotate in the threaded sleeve 10, and the bottom of the bolt 11 is rotated through the hinge shaft and the sleeve on the first rotating shaft 6, so that the entire first reel 3 rises or falls, thereby changing the distance between it and the second reel 5, thus completing the adjustment to adapt to reinforcing bars 15 of different sizes. The reinforcing bar 15 is transmitted to the left by the feeding mechanism to the cutting mechanism for further transmission. When it is transmitted to the infrared detector 25 in the distance control mechanism, the infrared detector 25 will detect whether the reinforcing bar 15 has reached the specified distance. After the reinforcing bar 15 reaches the specified distance, the infrared detector 25 will transmit an electrical signal to the controller 21, and the controller 21 will control the cutting mechanism to cut the reinforcing bar.

[0036] Specifically, the cutting mechanism includes a cylinder 22, which is fixed on the frame 16. An upper cutter head 18 is fixed to the lower end of the cylinder 22. A connecting plate 17 is fixed to the rear side wall of the frame 16. A lower cutter head 19 is fixed to the top of the connecting plate 17, and the lower cutter head 19 matches the upper cutter head 18.

[0037] In this embodiment: When cutting, the cutting mechanism drives the upper cutter head 18 to press down through the cylinder 22 and intersects with the lower cutter head 19 to cut the steel bar 15 that is transmitted between the upper cutter head 18 and the lower cutter head 19.

[0038] Specifically, a controller 21 is provided on the top of the frame 16, and the controller 21 is electrically connected to the cylinder 22 and the infrared detector 25.

[0039] In this embodiment, the controller 21 can work with the cylinder 22 and the infrared detector 25 to improve the automation level of the device and save manpower.

[0040] Specifically, the sliding sleeve 24 is threaded with a locking bolt 26, and a screw cap 27 is fixed on the locking bolt 26. The circumferential surface of the screw cap 27 is provided with anti-slip texture.

[0041] In this embodiment, the distance control mechanism can control the distance of the cut steel bar 15 by sliding the sleeve 24 onto the slide rail 23. In conjunction with the scale on the slide rail 23, the ease of use of the device can be further improved. After adjustment, the locking bolt 26 can be threaded onto the sleeve 24 and contact the slide rail 23 by turning the cap 27, thus fixing the distance of the sleeve 24 and preventing accidental sliding.

[0042] Specifically, a limiting plate 30 is fixed on the left side wall of the slide rail 23, and the limiting plate 30 matches the slide sleeve 24.

[0043] In this embodiment, the limiting plate 30 can effectively restrict the sliding position of the sliding sleeve 24 and prevent it from derailing.

[0044] Specifically, both the upper cutter head 18 and the lower cutter head 19 have a limiting groove 20 at one end, and both limiting grooves 20 are matched with the reinforcing bar 15.

[0045] In this embodiment, the setting of two limiting grooves 20 improves the limiting effect on the reinforcing bar 15 and prevents the reinforcing bar 15 from deviating during cutting.

[0046] Specifically, a feeding groove 28 is provided on the connecting plate 17, and an arc-shaped guide plate 29 is fixed on the front inner wall of the feeding groove 28, and the arc-shaped guide plate 29 is provided with a backward inclined arc.

[0047] In this embodiment, the setting of the feeding trough 28 and the arc-shaped guide plate 29 enables the steel bar 15 to roll outward through the feeding trough 28 and the arc-shaped guide plate 29 after the cutting mechanism has finished cutting, thereby realizing semi-automatic feeding and saving manpower.

[0048] Specifically, the right inner wall of the feed trough 28 and the left side wall of the cutter head 19 are on the same plane.

[0049] In this embodiment, placing the right inner wall of the feed trough 28 and the left side wall of the cutter head 19 on the same plane ensures that the cut steel bar 15 rolls out of the feed trough 28.

[0050] Specifically, a nut 12 is threaded onto the bolt 11, and the nut 12 is positioned between the threaded sleeve 10 and the swivel 13.

[0051] In this embodiment, the setting of nut 12 improves the restriction effect on the position of the adjusted bolt 11.

[0052] Specifically, both the bottom of the upright plate 1 and the frame 16 are fixed with triangular bases 14.

[0053] In this embodiment, the two triangular bases 14 fixed to the bottom of the upright plate 1 and the frame 16 improve the stability of the entire device.

[0054] The working principle and usage process of this invention: In use, the reinforcing bar 15 is first fed through the feeding mechanism in the device, inserting it into the gap between the first reel 3 and the second reel 5. The output of the motor 9 drives the rotation of the first reel 3. The rotation of the first reel 3 causes the reinforcing bar 15 to move to the left to engage with the second reel 5, improving transmission stability. When the size of the reinforcing bar 15 is different, the distance between the first reel 3 and the second reel 5 needs to be adjusted. This adjustment can be made through an adjustment mechanism. By manually rotating the rotating ring 13, the entire bolt 11 rotates within the threaded sleeve 10, and the bottom of the bolt 11 rotates through the hinge shaft and the sleeve on the first rotating shaft 6, causing the entire first reel 3 to rise or fall, thus changing the rotation. The distance between the reel and the second reel 5 is adjusted to accommodate steel bars 15 of different sizes. The steel bars 15 are conveyed to the left by the feeding mechanism and then to the cutting mechanism. When they reach the infrared detector 25 in the distance control mechanism, the infrared detector 25 detects whether the steel bars 15 have reached the designated distance. After the steel bars 15 reach the designated distance, the infrared detector 25 transmits an electrical signal to the controller 21, which then controls the cutting mechanism to cut the steel bars. During cutting, the upper cutter head 18 is driven down by the cylinder 22 and intersects with the lower cutter head 19 to cut the steel bars 15 conveyed between the upper cutter head 18 and the lower cutter head 19. The controller 21 is configured to work in conjunction with the cylinder 22 and the infrared detector. The device 25 improves the automation level of the equipment and saves manpower. The distance control mechanism allows for the control of the distance of the cutting steel bar 15 by sliding the sleeve 24 onto the slide rail 23. Combined with the scale on the slide rail 23, it further improves the ease of use of the device. After adjustment, the locking bolt 26 can be threaded onto the sleeve 24 and contact the slide rail 23 by turning the cap 27, thus fixing the distance of the sleeve 24 and preventing accidental sliding. The limiting plate 30 effectively restricts the sliding position of the sleeve 24, preventing derailment. The two limiting grooves 20 improve the restraint effect on the steel bar 15, preventing it from deviating during cutting. The feeding groove 28 and the arc-shaped guide plate 29 ensure that the steel bar is cut after the cutting mechanism completes the cutting process. The reinforcing bar 15 rolls outward through the feeding trough 28 and the arc-shaped guide plate 29, achieving semi-automatic feeding and saving manpower. Placing the right inner wall of the feeding trough 28 and the left side wall of the cutting head 19 on the same plane ensures that the cut reinforcing bar 15 rolls out of the feeding trough 28. The nut 12 improves the restriction effect on the position of the adjusted bolt 11. The two triangular bases 14 fixed to the bottom of the upright plate 1 and the frame 16 improve the stability of the entire device. The entire reinforcing bar cutting equipment has a reasonable and ingenious structure, changing the common cutting method, reducing noise and increasing efficiency. Simultaneously, the semi-automatic setting improves the efficiency of reinforcing bar cutting, saves manpower, and allows for controllable cutting distances. It is adaptable to reinforcing bars of different sizes and diameters, making it highly practical.This technology effectively solves the problems of existing rebar cutting equipment, which are mainly portable and bundled batch cutting devices. The former is portable but inefficient and unsuitable for construction projects, while the latter can bundle rebar for batch cutting, but its cutting distance is uncontrollable and loading / unloading is labor-intensive.
