Description

Technical Field

[0001] This utility model relates to the field of construction engineering equipment technology, specifically a high-efficiency steel bar bending machine for construction engineering. Background Technology

[0002] In construction engineering, rebar bending is a crucial process, requiring the rebar to bend into specific angles and shapes according to design requirements. Currently used rebar bending equipment suffers from the following drawbacks: First, it has limited functionality; most machines can only perform one of the bending or cutting functions, requiring multiple machines to work together to complete the entire rebar processing, resulting in a cumbersome and inefficient process. Second, the feed mechanism is inconvenient to adjust, making it difficult to adapt to the feeding needs of rebars of different diameters, and prone to slippage or unstable feeding. Third, the power transmission between the cutting and bending mechanisms is not well coordinated, leading to reduced processing accuracy. Fourth, it lacks an effective guiding mechanism, causing the rebar to easily deviate during feeding, affecting processing quality.

[0003] To address the aforementioned problems, this invention proposes a high-efficiency steel bar bending machine for building construction. By integrating feeding, cutting, and bending functions, and optimizing the adjustment mechanism and power transmission system, it improves the efficiency and accuracy of steel bar processing and adapts to the processing needs of steel bars of different specifications. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A high-efficiency steel bar bending machine for building construction includes a frame with a mounting plate vertically mounted on top. A feeding mechanism, a cutting mechanism, and a bending mechanism are arranged horizontally in a straight line on the mounting plate. The feeding mechanism includes a drive wheel and a drive motor, which is mounted on the mounting plate. A pressure wheel is rotatably mounted above the drive wheel. The output end of the drive motor is connected to the center of the drive wheel via a transmission shaft. The cutting mechanism includes an upper cutter head and a lower cutter head, which are offset, with the tip of the lower cutter head aligned with the side of the upper cutter head. The upper cutter head is fixedly mounted on the mounting plate, and the lower cutter head is connected to a telescopic mechanism for vertical up-and-down movement. The bending mechanism includes a support rod perpendicular to the mounting plate, with a bending pressure plate rotatably mounted on the outside of the support rod.

[0006] Preferably, the feeding mechanism is further provided with a guide mechanism on the side facing the input end. The guide mechanism includes two horizontal rows of guide wheels arranged vertically. The guide wheels are rotatably mounted on the mounting plate, and the reinforcing bar passes through the space between the two rows of guide wheels.

[0007] Preferably, the mounting plate is also provided with two sets of adjustment mechanisms. The clamping wheel and the guide wheel of the upper horizontal row are respectively set on the adjustment mechanism. The adjustment mechanism includes a mounting groove set on the top of the mounting plate, a crossbeam set on the upper part of the mounting groove, and sliding grooves set on the two inner side walls of the mounting groove. An adjustment plate is slidably set in the mounting groove, and the two sides of the adjustment plate are set in the sliding grooves. A threaded hole is set in the middle of the crossbeam. A screw is rotatably set on the top of the adjustment plate. The screw passes through the threaded hole and is threadedly connected to the threaded hole. A gripping part is set at the top of the screw.

[0008] Preferably, the output end of the drive motor is coaxially provided with a drive pulley, and the frame is also provided with a continuously variable transmission (CVT). The drive pulley is connected to the driven pulley on the input end of the CVT via a belt. The telescopic mechanism includes a connecting rod, which is connected to the bottom of the lower cutter head. A rotating shaft is arranged laterally on the frame, and a cam is provided on the rotating shaft. A contact frame is provided on the outside of the cam, and the other end of the connecting rod is connected to the top of the contact frame. A guide cylinder is provided on the outside of the connecting rod and is fixedly mounted on the frame. The output end of the CVT is provided with a second driven pulley, and the other end of the rotating shaft is provided with a third driven pulley. The second driven pulley and the third driven pulley are connected by a belt.

[0009] Preferably, the bending mechanism further includes a support frame, with a cylinder rotatably mounted on the top of the support frame, and the extended end of the cylinder rotatably connected to the top of the bending pressure plate.

[0010] Preferably, a discharge plate is provided below the cutting mechanism, and the discharge plate is inclined downward.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves integrated processing of steel bar conveying, cutting, and bending by sequentially arranging a feeding mechanism, a cutting mechanism, and a bending mechanism on the mounting plate. This eliminates the need to transfer steel bars between multiple machines, reduces process flow time, and improves processing efficiency.

[0012] The two horizontal rows of guide wheels in this utility model guide mechanism can provide stable guidance for the reinforcing bars, prevent the reinforcing bars from deviating during transportation, ensure that the reinforcing bars move in a straight line, and improve the accuracy of subsequent cutting and bending processes.

[0013] This utility model's adjustment mechanism uses a rotating screw to drive an adjustment plate to slide up and down along a groove, which can easily adjust the distance between the pressure wheel and the drive wheel, as well as between the upper and lower guide wheels, to adapt to the processing needs of steel bars of different diameters. The adjustment process is simple and quick, requiring no professional tools.

[0014] This invention uses a drive motor to provide power to both the feeding mechanism and the cutting mechanism. The cutting speed is adjusted by a continuously variable transmission, so that the feeding speed matches the cutting speed, avoiding problems such as incomplete cutting or waste of steel bars. At the same time, it simplifies the power system structure and reduces the equipment failure rate.

[0015] This utility model's bending mechanism uses a cylinder to drive the bending pressure plate to rotate around the support rod, which can precisely control the bending angle, ensure uniform bending force, and guarantee the bending quality of the steel bars. Compared with manual or hydraulic drive methods, it has a faster response speed and higher control precision.

[0016] The inclined unloading plate below the cutting mechanism of this invention can automatically guide the cut steel bars to the collection area, avoiding the accumulation of steel bars inside the equipment, reducing manual cleaning time, and improving operational safety.

[0022] like Figures 1-4 As shown in this embodiment, a high-efficiency rebar bending machine for building construction includes a frame 1, which is welded from structural steel and has sufficient structural strength and stability. A mounting plate 2, made of high-strength steel plate, is vertically welded to the top of the frame 1, serving as the mounting base for various functional mechanisms.

[0023] In this embodiment, a feeding mechanism 3, a cutting mechanism 4, and a bending mechanism 5 are arranged sequentially from left to right on the mounting plate 2, forming a linear processing production line. The feeding mechanism 3 includes a drive wheel 31 rotatably mounted on the mounting plate 2 via a bearing seat and a drive motor 32 that provides power. The drive motor 32 is a variable frequency motor, which is fixed to the frame 1 by bolts. Its output end is connected to the center key of the drive wheel 31 via a transmission shaft 34. A pressure wheel 33 is arranged above the drive wheel 31. The pressure wheel 33 is mounted on the adjusting plate 74 of the adjusting mechanism 7 via a wheel axle. During operation, the steel bar is clamped between the drive wheel 31 and the pressure wheel 33 and is conveyed forward as the drive wheel 31 rotates under the action of friction.

[0024] In this embodiment, a guide mechanism 6 is provided on the left side of the feeding mechanism 3. The guide mechanism 6 includes two rows of guide wheels 61. The guide wheels 61 are rotatably mounted on the mounting plate 2 or the adjusting plate 74 via axles. The upper row of guide wheels 61 is also mounted on the adjusting mechanism 7. The reinforcing bar passes between the two rows of guide wheels 61 to ensure that the reinforcing bar enters the feeding mechanism 3 along a predetermined trajectory.

[0025] In this embodiment, the mounting groove 71 of the adjusting mechanism 7 is formed on the top of the mounting plate 2. The crossbeam 72 is fixed to the top of the mounting groove 71 by bolts. The two sides of the adjusting plate 74 are embedded in the sliding grooves of the mounting groove 71 and can slide up and down along the sliding grooves. The lower end of the screw 76 is rotatably connected to the top of the adjusting plate 74 through a bearing, and the upper end passes through the threaded hole of the crossbeam 72 and is provided with a gripping part 77. When the gripping part 77 is rotated, the screw 76 drives the adjusting plate 74 to move up and down, thereby adjusting the height of the pressure wheel 33 and the upper row of guide wheels 61.

[0026] In this embodiment, the upper cutter head 41 of the cutting mechanism 4 is fixed to the mounting plate 2 by bolts, and the lower cutter head 42 is connected to the top end of the connecting rod 431 by bolts. The connecting rod 431 passes through the guide cylinder 15, which is fixed to the frame 1 by a bracket and guides the connecting rod 431. The lower end of the connecting rod 431 is welded to the contact frame 14, which is sleeved on the outside of the cam 13. The cam 13 is keyed to the rotating shaft 12, which is mounted on the frame 1 via a bearing seat.

[0027] In this embodiment, the output end of the drive motor 32 is also keyed to a drive pulley 8. The drive pulley 8 is connected to the driven pulley 11 at the input end of the continuously variable transmission (CVT) 9 via a belt 10. The CVT 9 is fixed to the frame 1 with bolts, and its output end driven pulley 16 is connected to the driven pulley 17 at the other end of the rotating shaft 12 via a belt 10. During operation, the drive motor 32 drives the CVT 9 and the rotating shaft 12 to rotate via belt drive. The cam 13 rotates with the rotating shaft 12, and pushes the connecting rod 431 up and down through the contact frame 14 to realize the cutting action of the lower cutter head 42. The cutting frequency can be changed by adjusting the CVT 9. The CVT and control technology are both existing technologies and will not be described in detail here.

[0028] In this embodiment, the support rod 51 of the bending mechanism 5 is welded to the mounting plate 2, the bending pressure plate 52 is rotatably sleeved on the outside of the support rod 51 via a bushing, the support frame 53 is welded to the frame 1, the cylinder body of the cylinder 54 is rotatably connected to the top of the support frame 53 via a pin, and the piston rod end of the cylinder 54 is rotatably connected to the ear plate at the top of the bending pressure plate 52 via a pin. When the piston rod of the cylinder 54 extends or retracts, it drives the bending pressure plate 52 to rotate around the support rod 51, bending the steel bar to the required angle.

[0029] In this embodiment, the unloading plate 18 below the cutting mechanism 4 is made of steel plate. One end is fixed to the mounting plate 2 by bolts, and the other end is inclined to the outside of the frame 1. The cut steel bars fall on the unloading plate 18 and slide down the inclined surface into the collection basket.

[0030] The working principle of the above technical solution is as follows: In use, the height of the clamping roller 33 and the upper guide roller 61 is adjusted according to the diameter of the rebar via the adjusting mechanism 7. One end of the rebar is inserted through the guide mechanism 61 and fed through the feeding mechanism 3 to the cutting mechanism 4 and the bending mechanism 5. The drive motor 32 is started, and the rebar is conveyed forward under the action of the drive roller 31 and the clamping roller 33. When the rebar reaches the preset length, the drive motor 32 stops conveying, and the lower cutter head 42 of the cutting mechanism 4 moves upward to cooperate with the upper cutter head 41 to cut the rebar. If bending is required, before or after cutting, the cylinder 54 is activated to drive the bending pressure plate 52 to rotate, bending the rebar to the set angle. The processed rebar slides out and is collected via the unloading plate 18. The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
