Description

Technical Field

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

[0002] Steel structure production refers to the process of manufacturing various steel structure components through steel processing and assembly. It is widely used in construction, bridges, machinery and other fields. Its production process mainly includes three major stages: raw material pretreatment, processing and manufacturing, and quality inspection. The raw materials are mostly hot-rolled steel plates and sections, which are first pretreated by rust removal and painting to enhance durability. In the processing stage, steel is processed into components such as beams, columns and trusses through processes such as cutting, welding, drilling and bending. Welding is the core process, which requires ensuring the strength of the joints. Complex components also require CNC machining to ensure accuracy. Production must strictly follow the design drawings and industry standards. Key links are controlled for quality through non-destructive testing and mechanical performance tests. Modern steel structure production uses a large amount of automated equipment, such as CNC cutting machines and welding robots, to improve efficiency and accuracy. After rust removal and painting, the finished products are transported to the site for assembly, finally forming a stable steel structure system with the advantages of high strength, fast construction and recyclability. When processing steel structures such as steel plates, steel plates are processed by cutting, welding, bending and stamping to make various key components.

[0003] Currently, when bending steel plates, especially thin steel plates, workers need to pick up the thin steel plate and place it under the bending plate to bend it. During the process, workers need to position the plate so that the rear end of the plate contacts the stop plate. However, this method can easily cause the plate to warp due to uneven force applied by the worker holding the rear end of the plate with one hand or on one side. This can lead to a certain degree of separation between the lower surface of the plate and the lower die, making it impossible to achieve a stable horizontal position and affecting the subsequent bending effect of the steel plate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bending device for steel structure production. It solves the problem that during operation, uneven force applied by workers when lifting the back end of the plate with one hand or on one side can easily cause the plate to warp, resulting in a certain degree of separation between the front and back or the rear end of the plate and the lower die, making it impossible to form a stable horizontal posture and affecting the subsequent bending processing effect of the steel plate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bending device for steel structure production, comprising a bending table, a lower die fixedly mounted on the upper surface of the bending table, an mounting frame fixedly mounted on the front surface of the bending table, the lower end of the mounting frame being open, and a bending plate being slidably mounted up and down inside the mounting frame; An auxiliary positioning mechanism is installed on the bending table.

Four mounting blocks are fixedly connected to the front surface of the baffle plate in a rectangular array. The four electric push rods are respectively fixedly installed on the distant surfaces of the four mounting blocks. The telescopic ends of the four electric push rods slide through to the adjacent surfaces of the four mounting blocks.

A baffle plate 7 is slidably installed on the upper surface of the bending table 1. Four mounting blocks 8 are fixedly connected to the front surface of the baffle plate 7 in a rectangular array. The four electric push rods 5 are respectively fixedly installed on the distant surfaces of the four mounting blocks 8. The telescopic ends of the four electric push rods 5 slide through to the adjacent surfaces of the four mounting blocks 8. The two limiting plates 6 are respectively fixedly installed on the telescopic ends of the two upper electric push rods 5 and the two lower electric push rods 5.

[0016] Furthermore, the auxiliary positioning mechanism also includes a slider 9, a first rectangular groove 10 is provided on the upper surface of the bending table 1, the slider 9 is slidably installed inside the first rectangular groove 10, the slider 9 is fixedly connected to the baffle plate 7, and an installation groove 11 is provided on the rear surface of the bending table 1.

[0017] Furthermore, the electric push rod 5 drives the two limiting plates 6 to move, so that the limiting plates limit the steel plate from the top and bottom. Combined with the front and rear positioning of the baffle plate 7, an effective positioning effect is formed, which effectively avoids the problem of steel plate tilting caused by uneven force when the operator holds the steel plate. This ensures the fit between the steel plate and the lower mold 2, guarantees the accuracy of the bending dimensions, improves the processing effect of the steel plate, and thus improves production efficiency.

[0018] Furthermore, a threaded rod 12 is rotatably mounted on the inner wall of the first rectangular groove 10. The threaded rod 12 is threadedly connected to the slider 9. A motor 13 is fixedly mounted inside the mounting groove 11. The output end of the motor 13 rotatably penetrates into the interior of the first rectangular groove 10. The motor 13 is fixedly connected to the threaded rod 12.

[0019] Furthermore, two second rectangular grooves 14 are formed on the upper surface of the bending table 1, and two electric push rods 5 on the lower side are respectively located inside the two second rectangular grooves 14.

[0020] Furthermore, a hydraulic component 15 is fixedly installed on the upper surface of the mounting frame 3, and the telescopic end of the hydraulic component 15 slides through into the interior of the mounting frame 3. The bending plate 4 is fixedly connected to the telescopic end of the hydraulic component 15.

[0021] Furthermore, guide plates 16 are fixedly connected to both ends of the bending plate 4, and guide grooves 17 are provided on the mounting bracket 3 at the positions corresponding to the guide plates 16. The guide plates 16 and guide grooves 17 are slidably connected internally.

[0022] Furthermore, the front ends of the adjacent surfaces of the two limiting plates 6 are both inclined.

[0023] Furthermore, motor 13 is a servo motor, and the output shaft of motor 13 is fixedly connected to the end of threaded rod 12 via a coupling.

[0024] Furthermore, the baffle plate 7 and the slider 9 are fixed together by welding.

[0025] Furthermore, the left and right surfaces of the slider 9 are in close contact with the inner wall of the first rectangular groove 10.

[0026] Further, the workers move the thin steel plate onto the bending table 1, aligning the front end of the steel plate with the V-groove of the lower die 2, and initially fitting the rear end against the front surface of the baffle plate 7, completing the basic positioning. At this time, the four electric push rods 5 in the auxiliary positioning mechanism are in a retracted state, and the two limit plates 6 are located on the upper and lower sides of the steel plate respectively. The distance between the limit plates 6 and the steel plate is adjusted by extending and retracting the electric push rods 5 to ensure that the steel plate does not shift in the vertical direction, ensuring that the steel plate is in horizontal contact with the surface of the lower die 2, forming a stable pre-positioning posture. After starting the equipment, the hydraulic component 15 on the mounting frame 3 drives the bending plate 4 to slide downward along the guide groove 17. The bending plate 4 gradually approaches the lower die 2 to perform the bending operation on the thin steel plate. While the steel plate is touched and pressure is applied, the motor 13 drives the threaded rod 12 to rotate in the first rectangular groove 10 through the drive component in the mounting groove 11. The slider 9, which is threaded to the threaded rod 12, drives the baffle plate 7 to slide backward. The two limit plates 6 move away from the steel plate synchronously under the action of the electric push rod 5, so as to avoid interference between the baffle plate 7 and the limit plate 6 and the steel plate during the bending process, and ensure that the bending action is carried out smoothly. After the bending plate 4 completes the bending action, it resets upward under the drive of the hydraulic component 15. Then, the motor 13 reverses and drives the baffle plate 7 to slide forward to the initial position. The electric push rod 5 drives the limit plate 6 to reset, and the worker can take out the bent thin steel plate to complete one bending processing cycle.
