Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat steel horizontal bending technology, and more specifically, to a flat steel horizontal bending machine. Background Technology
[0002] Horizontal bending of flat steel is a common metal processing technique, primarily achieved through specific mechanical equipment, such as a flat steel horizontal bending machine. During operation, the flat steel is placed on the machine's worktable, and pressure generated by a power system, transmitted through a transmission device, acts on the flat steel, causing it to undergo plastic deformation in the horizontal direction. This process offers numerous advantages: it allows for precise control of the bending angle and radius, ensuring processing accuracy and greatly meeting the dimensional requirements of various engineering projects for flat steel bending. Furthermore, it boasts high processing efficiency, enabling the rapid completion of large-scale flat steel bending tasks and significantly improving production progress. It is widely used in the construction industry for creating bent connectors in steel structure buildings.
[0003] When flat steel is bent, rusted parts often detach and fall onto the machine. During bending, as the flat steel deforms under stress, the already weak bond between the rust and the substrate is further weakened. Especially at the bending points, stress concentration makes it easier for the rust to peel off the surface of the flat steel. These detached rust fragments are scattered throughout the bending machine as the flat steel moves and the machine operates, such as on the worktable, between transmission components, and on the die surface. Rust on the machine affects its cleanliness, making the working environment cluttered; furthermore, rust fragments may enter the machine's precision transmission components, affecting the machine's operational accuracy and lifespan, and may even cause machine malfunctions, increasing maintenance costs and downtime.

[0023] A connecting pipe 10 is fixedly connected to the top of the airflow control box 9, and the connecting pipe 10 is connected to the second air pipe 6. A hydraulic motor 11 is fixedly connected to the bottom of the operating platform 2, and the hydraulic motor 11 is connected to an external hydraulic pump. A movable seat 12 is rotatably connected to the top of the operating platform 2, and the bottom of the movable seat 12 is fixedly connected to the output shaft of the hydraulic motor 11. A bending seat 13 is fixedly connected to the top of the movable seat 12, and an extrusion table 14 is fixedly connected to the top of the bending seat 13. The extrusion table 14 is circular. A support seat 15 is fixedly connected to the top of the movable seat 12, and a moving block is slidably connected to the top of the movable seat 12. 16. A first threaded rod 17 is rotatably connected to the movable block 16. The first threaded rod 17 is located inside the support base 15. The first threaded rod 17 and the support base 15 are connected by a threaded engagement. A limit assembly is provided on the top of the operating table 2. The limit assembly includes a fixed seat 18 fixedly connected to the top of the operating table 2. The fixed seat 18 is L-shaped. A movable seat 19 is slidably connected to the fixed seat 18. A roller 20 is rotatably connected to the inner side of the movable seat 19. A second threaded rod 21 is connected to the fixed seat 18 by a threaded engagement. The end of the second threaded rod 21 is rotatably connected to the outer wall of the movable seat 19.
[0024] The working principle of this flat steel horizontal bending machine is as follows: The flat steel is placed on the upper surface of the bending seat 13 and is clamped between the moving block 16 and the extrusion table 14. Air pressure is supplied to the cylinder 4 through the first air pipe 5. The telescopic end of the cylinder 4 drives the fixed plate 7 to move downward, pressing the flat steel. By controlling the rotation of the hydraulic motor 11, the moving seat 12 is driven to rotate. The moving seat 12 drives the moving block 16 to make a circular motion. When the moving block 16 moves, it applies horizontal pressure to the flat steel. The roller 20 on the limiting component limits the flat steel. When the moving block 16 moves, the flat steel is gradually bent and presents a horizontally bent state, thus completing the horizontal bending of the flat steel.
[0025] After the flat steel is bent, the cylinder 4 is pressurized through the second air pipe 6, causing the cylinder 4 to move the fixed plate 7 upward, relieving the pressure on the flat steel. During this process, as the fixed plate 7 moves upward, the push block 72 is pressed by the protrusion 71, causing the push block 72 to overcome the elastic force of the spring 75 and move in the direction of the spring 75, so that the air hole 73 and the air passage 74 are connected. The airflow in the second air pipe 6 passes through the connecting pipe 10, the air passage 74 and the air hole 73, and is blown out from the air outlet pipe 76. The airflow passes over the upper surface of the operating table 2, cleaning the rust particles on the bending seat 13 and the upper surface of the operating table 2, preventing rust from entering the mechanical moving parts of the bending machine and causing damage to the bending machine.
[0026] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
