Description

Technical Field

[0001] This utility model relates to the field of steel bar bending technology, specifically a steel bar bending device for building engineering. Background Technology

[0002] Reinforcing bars are long, thin steel bars, including plain round bars, ribbed bars, and twisted bars. They are also one of the main building materials in construction projects, primarily bearing the tensile stress of concrete. In current building construction, reinforcing bars often need to be bent to ensure the stability of connections in areas such as building corners.

[0003] Chinese patent (authorization announcement number: CN 212664760 U, authorization announcement date: 2021.03.09) proposes a steel bar bending device for construction engineering. This steel bar bending device for construction engineering, through the arrangement of T-shaped groove, slider, stop block, fixing bolt, arc through groove and machine box, allows the slider to slide inside the T-shaped groove on the upper surface of the machine box and drive the stop block to move. The arc through groove increases the contact area between the stop block and the steel bar, so that the stop block can better restrict the movement of the steel bar and prevent the steel bar from breaking out. By tightening the fixing bolt, the slider can be fixed inside the T-shaped groove, achieving the effect of effectively restricting the steel bar and preventing the steel bar from breaking out.

[0004] When steel bars are bent, metal friction generates a large amount of metal dust, which can affect human health. However, the aforementioned steel bar bending device does not have a metal dust collection device, and the device does not have a warning mechanism for personnel approaching the bending area. Operators may accidentally touch the danger zone or approach the danger zone from a blind spot, which may lead to collisions or being ejected by the steel bars. Therefore, we propose a steel bar bending device for construction engineering. Utility Model Content

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a steel bar bending device for construction engineering, including a device body 1, a fixed column 14 fixedly connected to the middle of the top side of the device body 1, a plurality of clamping components installed on the top left side of the device body 1, a bending component installed on the top side inside the device body 1, a dust suction component installed on the top rear side of the device body 1, and a material blocking component installed on the top right side of the device body 1.

[0023] When using this steel bar bending device for construction projects, the steel bar to be bent is placed on the top of the equipment body 1, and the steel bar is clamped and fixed by the clamping component. Then, the bending component drives the bending action inside the top side of the equipment body 1, and the fixed column 14 serves as a support reference to achieve precise bending of the steel bar. The dust suction component is located on the top rear side of the equipment body 1, and removes the metal dust generated during the bending process by negative pressure to ensure a clean working environment. The material blocking component is installed on the top right side of the equipment body 1 to guide the positioning of the steel bar bending length and complete the steel bar bending operation in a coordinated manner.

[0024] The dust collection assembly includes a mounting plate 6, which is fixedly installed on the top rear side of the device body 1. A dust collection hopper 7 is installed on the front of the mounting plate 6. A collection cylinder 18 is fixedly installed on the rear side of the device body 1. A connecting pipe 8 is fixedly connected to the top of the collection cylinder 18. The input end of the connecting pipe 8 is fixedly connected to the top of the dust collection hopper 7. A negative pressure fan 20 is fixedly installed on the bottom side inside the device body 1. A negative pressure pipe 21 is fixedly connected to the input end of the negative pressure fan 20. The input end of the negative pressure pipe 21 is fixedly connected to the bottom of the collection cylinder 18. A filter cylinder 30 is provided inside the collection cylinder 18.

[0025] When in use, the dust collection component is fixed to the top rear side of the equipment body 1 by the mounting plate 6. The dust collection hopper 7 is located on the top of the equipment body 1, facing the area where the steel bars are bent. The negative pressure fan 20 is installed on the bottom side inside the equipment and is connected to the bottom of the collection cylinder 18 through the negative pressure pipe 21 to form a negative pressure airflow. When the negative pressure fan 20 is started, the airflow draws in metal dust through the dust collection hopper 7 and enters the collection cylinder 18 through the connecting pipe 8. The dust is intercepted by the internal filter cylinder 30, realizing efficient collection and discharge of dust.

[0026] The clamping assembly includes a sliding groove 3, which is located on the top of the device body 1. Sliding blocks 4 are slidably connected to the front and rear sides of the sliding groove 3. Rollers 5 are rotatably mounted on the top of the two sets of sliding blocks 4. A bidirectional screw 28 is rotatably inserted between the front and rear sides of the sliding groove 3. The two sets of sliding blocks 4 are threaded onto the bidirectional screw 28. A knob 29 is fixedly connected to the rear end of the bidirectional screw 28.

[0027] When the clamping assembly is in use, the sliding groove 3 is opened on the top of the equipment body 1, and the bidirectional screw 28 extends horizontally through the front and rear sides of the sliding groove 3. A knob 29 is fixed at one end. When the knob 29 is rotated, the bidirectional screw 28 rotates, driving the two sets of sliding blocks 4 to move towards or away from each other along the sliding groove 3. The roller 5 clamps or releases the steel bar placed on the top. The rotation of the roller 5 reduces the friction of the steel bar, ensuring stable clamping while reducing wear.

[0028] The bending assembly includes a rotating disk 26, which is rotatably mounted on the inner top side of the equipment body 1. A gear ring 27 is fixedly sleeved on the outer surface of the rotating disk 26. A bending block 10 is fixedly connected to the top of the rotating disk 26. An arc-shaped slide groove 9 is opened through the middle of the top side of the equipment body 1. A scale 15 is set around the arc-shaped slide groove 9 on the top side of the equipment body 1. The bottom of the bending block 10 is slidably connected to the arc-shaped slide groove 9. A drive motor 19 is fixedly mounted on the inner right side of the equipment body 1. A gear 22 is fixedly connected to the output shaft end of the drive motor 19. A rotating rod 23 is also rotatably mounted on the inner top side of the equipment body 1. A gear 24 and a gear 25 are fixedly sleeved on the top and bottom sides of the rotating rod 23, respectively. Gear 22 meshes with gear 25, and gear 24 meshes with gear ring 27.

[0029] When the bending assembly is in use, the drive motor 19 meshes with the gear 25 at the bottom of the rotating rod 23 through the gear 22, driving the rotating rod 23 to rotate. The gear 24 at the top of the rotating rod 23 meshes with the gear ring 27, amplifying the output torque of the drive motor 19 and driving the rotating disk 26 and the bending block 10 to rotate synchronously. The bottom of the bending block 10 is slidably connected in the arc-shaped slide groove 9 on the top side of the equipment body 1, and can move along the arc-shaped slide groove 9 to adjust the bending angle. The scale 15 is used to precisely control the bending position and realize precise bending operations at different angles.

[0030] The material blocking assembly includes a slide rail 11, which is fixedly installed on the top right side of the equipment body 1. A sliding plate 31 is slidably mounted on the slide rail 11. A baffle 33 is fixedly connected to the top left side of the sliding plate 31. A bolt 32 is threaded through the top of the sliding plate 31. The bottom end of the bolt 32 abuts against the top side of the slide rail 11. A scale 16 is also provided on the top side of the slide rail 11.

[0031] When using the baffle assembly, loosen the bolt 32 to slide the sliding plate 31 along the slide rail 11, adjust the baffle 33 to the preset position, and then tighten the bolt 32 to fix it. It is used to position the bending length of the reinforcing bar. The scale 16 on the top side of the slide rail 11 can help to accurately adjust the position of the baffle 33.

[0032] An infrared sensor 12 and an alarm 13 are installed on the top front side of the equipment body 1. The infrared sensor 12 monitors the activity range of personnel near the top front side of the equipment body 1 in real time. When it detects that the operator is approaching the dangerous area of ​​bending operation, it immediately sends a signal to the control system, triggering the alarm 13 to sound an alarm and warn the personnel to evacuate.

[0033] A temperature sensor 17 is installed on the outer surface of the fixed column 14 to monitor the temperature change of the contact area between the steel bar and the fixed column 14 in real time during the bending process. When the temperature rises abnormally, the temperature sensor 17 transmits the signal to the control system, which automatically adjusts the speed of the drive motor 19 or stops the operation.

[0034] The device body 1 is equipped with four casters 2 at the bottom corners, providing stable support and flexible movement capability.

[0035] Working principle: When using this steel bar bending device for construction engineering, the steel bar to be bent is placed on the top of the equipment body 1. The sliding groove 3 is opened on the top of the equipment body 1. The bidirectional screw 28 passes horizontally through the front and rear sides of the sliding groove 3, and a knob 29 is fixed at one end. When the knob 29 is rotated, the bidirectional screw 28 rotates, driving the two sets of sliding blocks 4 to move towards each other along the sliding groove 3. The rollers 5 clamp the steel bar placed on the top. The rotation of the rollers 5 reduces the friction of the steel bar, ensuring stable clamping while reducing wear. Subsequently, the drive motor 19 communicates with the rotating part of the machine through gear 22. The gear 25 at the bottom of the moving rod 23 meshes, driving the rotating rod 23 to rotate. The gear 24 at the top of the rotating rod 23 meshes with the gear ring 27, amplifying the output torque of the drive motor 19 and driving the rotating disk 26 and bending block 10 to rotate synchronously. With the fixed column 14 as the support reference, the steel bar is accurately bent. The bottom of the bending block 10 is slidably connected in the arc-shaped slide groove 9 on the top side of the equipment body 1. It can move along the arc-shaped slide groove 9 to adjust the bending angle. The scale 15 is used to precisely control the bending position and realize the precise bending operation at different angles.

[0036] During the rebar bending process, the mounting plate 6 is fixed to the top rear side of the equipment body 1, the dust collection hopper 7 is located on the top of the equipment body 1, directly facing the rebar bending area, and the negative pressure fan 20 is installed inside the bottom side of the equipment. It is connected to the bottom of the collection cylinder 18 through the negative pressure pipe 21 to form a negative pressure airflow. When the negative pressure fan 20 is started, the airflow draws in metal dust through the dust collection hopper 7 and enters the collection cylinder 18 through the connecting pipe 8. The dust is intercepted by the internal filter cylinder 30, realizing efficient collection and discharge of dust. By removing the metal dust generated during the bending process through negative pressure suction, the working environment is kept clean.

[0037] Before bending the steel bar, loosen the bolt 32 so that the sliding plate 31 can slide along the slide rail 11. After adjusting the baffle 33 to the preset position, tighten the bolt 32 to fix it. This is used to block and position the bending length of the steel bar. The scale 16 on the top side of the slide rail 11 can help to accurately adjust the position of the baffle 33 and complete the steel bar bending operation together.

[0038] Furthermore, during the bending process of the steel bars, the infrared sensor 12 monitors the activity range of personnel near the top front side of the equipment body 1 in real time. When it detects that the operator is approaching the dangerous area of ​​the bending operation, it immediately sends a signal to the control system, triggering the alarm 13 to issue an alarm and warn the personnel to evacuate.
