Description

Technical Field

[0001] This utility model belongs to the field of steel bar bending technology, and in particular relates to a steel bar bending machine for construction engineering. Background Technology

[0002] In construction work, steel bars need to be bent for binding. During the bending process, the steel bars need to be placed in the designated load-bearing position and then pressed into shape by pressing both ends. However, the surface of the steel bars is often covered with impurities and oxide layers. High-intensity pressing will leave impurities at the load-bearing position. These impurities will stick to the surface when subjected to pressure, which can easily damage the surface of the steel bars during subsequent bending. At this time, it is necessary to clean them. However, manual cleaning requires being close to the bending position of the bending machine, which is easy to accidentally touch and is quite dangerous, making it difficult to ensure work safety.

Detailed Implementation

[0025] In the following description, embodiments of the steel bar bending machine for construction engineering according to the present invention will be described with reference to the accompanying drawings.

[0026] Figure 1-5 This invention illustrates a steel bar bending machine for construction engineering according to an embodiment of the present invention. It includes a workbench 1, a base 6 fixedly mounted at one end of the top of the workbench 1, a bearing block 5 fixedly mounted at one end of the top of the base 6, a motor 7 fixedly mounted inside the workbench 1, an electric telescopic rod 8 slidably mounted at one end of the top of the motor 7, a toothed plate 9 fixedly mounted at one end of the top of the electric telescopic rod 8, a rotating rod 10 rotatably mounted on one side of the bearing block 5, a gear 11 fixedly mounted on one side of the rotating rod 10, and the gear 11 and the toothed plate 9 being meshed. The other side of the rotating rod 10... A movable plate 12 is fixedly installed, and a brush plate 13 is fixedly installed at one end of the top of the movable plate 12. The brush plate 13 cooperates with the bearing block 5. A scraper 19 is slidably installed on one side of the top of the base 6. A slider 17 is slidably installed inside the base 6. A steel cable 18 is installed on one side of the scraper 19, and the slider 17 and the scraper 19 are connected by the steel cable 18. A rotating shaft 16 is rotatably installed at one end of the bottom of the base 6. A crossbar 15 is fixedly installed in the middle of the rotating shaft 16. The crossbar 15 cooperates with the slider 17. A fixing block 14 is fixedly installed on one side of the toothed plate 9.

[0027] Specifically, the impurity cleaning structure automatically removes impurities adhering to the bending position, preventing them from sticking together and ensuring that subsequent rebar bending work can proceed normally without damaging the rebar surface. At the same time, no manual cleaning is required from workers, and the various components at the bending position are not touched, thus improving work safety.

[0028] A limiting block 22 is fixedly installed on one side of the base 6. The limiting block 22 has a slot in the middle that matches the toothed plate 9. The toothed plate 9 and the limiting block 22 are slidably connected.

[0029] Specifically, by setting the limit block 22, the displacement of the toothed plate 9 can be limited, so that the toothed plate 9 will not deviate during the movement, ensuring that the transmission effect is stable enough and improving the overall operational stability.

[0030] A spring 20 is installed on one side of the scraper 19, and a slot that matches the spring 20 is opened on one side of the base 6. The scraper 19 and the base 6 are connected by the spring 20. A pulley 21 is rotatably installed inside the base 6, and the pulley 21 matches the steel cable 18.

[0031] Specifically, by setting the spring 20 and the scraper 19, the position where the brush plate 13 is placed can be automatically cleaned while the brush plate 13 is cleaning, ensuring better cleaning effect. At the same time, the automatic retraction setting will not affect the normal placement of the brush plate 13.

[0032] A slot is provided on one side of the bottom of the base 6 to cooperate with the fixing block 14, and the fixing block 14 and the base 6 are slidably connected. The fixing block 14 cooperates with the crossbar 15.

[0033] Specifically, the groove at the bottom of the base 6 further limits the movement of the toothed plate 9 and the fixed block 14, making the limiting effect more stable and reducing friction, so that the fixed block 14 and the crossbar 15 are more effortless to contact.

[0034] The top of the workbench 1 has material drop troughs 4 on both sides, and a ventilation pipe 23 is provided on one side inside the material drop trough 4, which is connected to the outside.

[0035] Specifically, by setting up ventilation pipe 23, an external air pump can be connected to collect impurities inside the ventilation pipe 23, eliminating the need for manual cleaning by staff and improving overall safety.

[0036] The base 6 has a slot inside that mates with the slider 17, and an arc-shaped slot inside that mates with the crossbar 15.

[0037] Specifically, the slot inside the base 6 ensures that the movement of the slider 17 is limited and will not deviate, while providing sufficient rotation space for the crossbar 15 and preventing obstruction of its rotation.

[0038] Working Principle: When using this utility model, the user places the reinforcing bar on top of the bearing block 5, then activates the support frame 2. Under the action of the hydraulic structure, it is pressed down. At this time, the top of the bearing block 5 is subjected to greater pressure during the bending process, and impurities will adhere due to the pressure. After bending is completed, the reinforcing bar is removed, and then the motor 7 is activated, causing the motor 7 to drive the electric telescopic rod 8 to move upward. When the electric telescopic rod 8 moves upward, it drives the toothed plate 9 to move upward. When the toothed plate 9 moves upward, the gear 11 meshing with the toothed plate 9 rotates, thereby driving the rotating rod 10 to rotate. When the rotating rod 10 rotates, it drives the movable plate 12 to rotate around the rotating rod 10. When the movable plate 12 moves, it drives the brush plate 13 to rotate around the bearing block 5. At this time, the metal bristles clean the bearing block 5. It should be noted that if the adhesion strength is large, the electric telescopic rod 8 can be driven to move back and forth multiple times to achieve complete cleaning. At this time, the bearing block Impurities inside the 5 are affected by the brush plate 13 and fall from both sides of the support block 5, and then fall into the material trough 4. At this time, the impurities inside the material trough 4 can be collected by an external air pump connected to the ventilation pipe 23. At the same time, a few impurities may adhere to the inside of the brush plate 13 during operation. When the brush plate 13 is placed, they fall to one side of the top of the base 6. When the movable plate 12 retracts to its original position, the toothed plate 9 moves, which drives the fixed block 14 to move down. When the fixed block 14 moves down, the fixed block 14 squeezes the crossbar 15. At this time, the crossbar 15 on one side is squeezed, and the slider 17 on the other side is lifted by the crossbar 15 rotating around the rotating shaft 16. At this time, the slider 17 moves up and pulls the steel cable 18 to drive the scraper 19 to retract. As mentioned above, when the brush plate 13 starts cleaning, the spring 20 loses its compression and automatically pops out, so that the scraper 19 cleans the placement position of the brush plate 13 and pushes the residue into the material trough 4.

[0039] Furthermore, the impurity cleaning structure, through automatic brushing, removes impurities adhering to the bending position, preventing them from sticking together and ensuring the subsequent rebar bending work proceeds normally without damaging the rebar surface. Simultaneously, manual cleaning is unnecessary, avoiding contact with various components at the bending position and improving work safety. The limiting block 22 ensures the displacement of the toothed plate 9 is limited, preventing deviation during movement and ensuring stable transmission, thus improving overall operational stability. The spring 20 and scraper 19 automatically clean the area where the brush plate 13 is placed while the brush plate 13 is cleaning, ensuring cleaning efficiency. The effect is better, and the automatic retraction setting will not affect the normal placement of the brush plate 13. The slot opened at the bottom of the base 6 further limits the movement of the toothed plate 9 and the fixed block 14, making the limiting effect more stable and reducing friction, making it easier for the fixed block 14 and the crossbar 15 to contact. By setting the ventilation pipe 23, the impurities inside the ventilation pipe 23 can be collected by connecting an external air pump, eliminating the need for manual cleaning by staff and improving overall safety. The slot opened inside the base 6 ensures that the movement of the slider 17 is limited and will not deviate, while providing sufficient rotation space for the crossbar 15 and not obstructing the rotation of the crossbar 15.

[0040] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model lies in optimizing and combining existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology without involving improvements to the internal software of the hardware.
