Description

Technical Field

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

[0002] A bending device used for steel structure processing is an industrial equipment specifically designed for cold or hot bending of structural components such as steel profiles and plates. Its core function is to apply enormous force to cause the tough steel to undergo plastic deformation at a predetermined position, thereby obtaining the specific angle or curve shape required by the design.

[0003] In traditional bending processes, the positioning and clamping of workpieces often rely on manual operation or simple mechanical stops. Traditional methods cannot make quick and accurate adaptive adjustments according to workpiece size and bending requirements, and rely too much on the experience of operators, thus introducing human error. Utility Model Content

[0004] The purpose of this utility model is to provide a bending device for steel structure processing, which solves the problems of inaccurate positioning and insecure clamping.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a bending device for steel structure processing, including a base, a push rod at one end of the base along its length, an oil spray tank on one side of the push rod, a positioning block for pressing the workpiece above the base, and an air spray can at the other end of the base along its length.

[0006] Furthermore, the base is provided with symmetrically arranged processing channels for accommodating workpieces of different sizes. The bending parts of the processing channels are provided with replaceable bending plates with bending surfaces of different shapes.

[0007] Furthermore, the positioning block is connected to the drive motor and is driven to rotate by the drive motor. The positioning block is provided with an adjustable positioning block, and the positioning block is connected to an extension rod, which is driven by a positioning pneumatic cylinder.

[0008] Furthermore, the push rod is connected to a push pneumatic cylinder, which drives the workpiece. The output end of the push pneumatic cylinder is connected to a push rod, and the front end of the push rod is provided with a limiting plate. The height of the limiting plate is not higher than the lower surface of the workpiece after it is placed.

[0009] Furthermore, the oil spraying barrel is equipped with an oil storage tank inside, and the oil storage tank is connected to an oil spray nozzle through a pipeline for spraying lubricating oil onto the surface of the workpiece.

[0010] Furthermore, the jet can is disposed on a rotating base, which is located beside the base. An air storage tank is provided on the rotating base, and the air storage tank is connected to a jet nozzle. The jet nozzle sprays towards the bending area of ​​the workpiece.

[0011] This utility model has the following beneficial effects: (1) The present invention uses the processing channels symmetrically arranged on the base to allow the I-shaped steel or square steel to be placed in and to be initially centered and positioned naturally, which restricts its horizontal freedom and provides a reference for subsequent processing, thus solving the problem of inaccurate positioning.

[0012] (2) This utility model uses a drive motor to adjust the overall angle of the pressure block so that it can contact the I-shaped steel or square steel of different shapes or requirements in the best posture. Then, the positioning cylinder drives the adjustable positioning block to provide stable and controllable downward pressure. This pneumatic method has constant pressure, which can ensure that the workpiece is firmly fixed in the whole bending process, avoid the displacement problem caused by insufficient clamping force, and solve the problem of poor clamping in the prior art.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 As shown, this utility model is a bending device for steel structure processing, including a base 1, a push rod 3 at one end of the base 1 along its length direction, an oil spray tank 4 on one side of the push rod 3, a positioning block 2 for pressing the workpiece on the top of the base 1, and an air spray can 5 at the other end of the base 1 along its length direction.

[0018] The base 1 is provided with symmetrically arranged processing channels 11, and the bending part of the processing channel 11 is provided with a replaceable bending plate 12, the bending plate 12 having a bending surface of different shapes. Before processing, the I-beams or square steel are placed in symmetrically arranged processing channels 11. The processing channels 11 are set according to different national standard sizes. During bending operations, the appropriate processing channel 11 and bending plate 12 can be selected according to the size of the workpiece, so that the workpiece can move along the path of the processing channel 11 during the bending process to form the required structural shape. This design enhances the versatility and adaptability of the device, effectively reduces the mold replacement and adjustment time, and improves processing efficiency and consistency of bending shape. The positioning block 2 is connected to the drive motor 21 and is driven to rotate by the drive motor 21. The positioning block 2 is provided with an adjustable positioning block 22, and the positioning block 22 is connected to an extension rod, which is driven by the positioning pneumatic cylinder 23. Among them, the drive motor 21 drives the positioning block 2 to rotate to a predetermined angle to adapt to different processing postures. Then, the positioning pneumatic cylinder 23 drives the adjustable positioning block 22 to move up and down through the extension rod, thereby accurately pressing or releasing the workpiece, so that the I-shaped steel avoids the structure of swaying up and down during the processing and bending process. At the same time, it presses the connecting wings of the I-shaped steel or square steel, so that the I-shaped steel or square steel will not tear due to the angle deviation, effectively ensuring the stability of the workpiece during the bending process and improving the processing accuracy and operation efficiency. The push rod 3 is connected to the push pneumatic cylinder 31, which drives the workpiece. The output end of the push pneumatic cylinder 31 is connected to the push rod 32. The front end of the push rod 32 is provided with a limiting plate 33. The height of the limiting plate 33 is not higher than the lower surface of the workpiece after it is placed. The oil spraying tank 4 has an oil storage tank 42 inside, and the oil storage tank 42 is connected to an oil spray nozzle 41 through a pipeline for spraying lubricating oil onto the surface of the workpiece. The lubricating oil in the oil storage tank 42 is delivered to the oil nozzle 41 through the pipeline and sprayed evenly on the surface of the workpiece before bending. This pushes the pneumatic cylinder 31 to drive the push rod 32 forward to the position of the limit plate 33, thereby smoothly pushing the workpiece to the bending station. This lubrication effect can significantly reduce the friction between the material and the mold during bending, effectively prevent the workpiece surface from being scratched or cracked, improve the bending forming quality and surface finish, and at the same time reduce processing resistance and mold wear, thus extending the service life of the equipment. The air tank 5 is set on the rotating base 51, which is located next to the base 1. The rotating base 51 is provided with an air storage tank 52, which is connected to an air nozzle 53. The air nozzle 53 sprays towards the bending area of ​​the workpiece. The gas storage tank 52 pressurizes the cold air and ejects it through the jet nozzle 53. The rotating base 51 can adjust the angle of the jet nozzle 53 so that the cold air is sprayed onto the workpiece bending area and cools the workpiece placed on the base 1. This directional cooling function can cool the base 1 and the workpiece before processing, while cleaning up the residual debris on the working position and cooling down before spraying lubricating oil to achieve the safety performance of the processing system. Specifically, the steel structure workpiece to be processed is placed on the base 1, and the push rod 3 pushes the workpiece forward to the bending station. The positioning block 2 presses down to fix the workpiece. During the bending process, the oil spray tank 4 sprays lubricating oil onto the bending area of ​​the workpiece to reduce friction and deformation. After the bending is completed, the air spray can 5 sprays water to cool the bending area to quickly set the shape and improve the material properties. This utility model integrates pushing, pressing, lubrication and cooling functions into one, which can effectively improve the bending processing accuracy, surface quality and production efficiency, and extend the service life of the mold.

[0019] In use, the processed I-beam or square steel is placed in front of the processing channel 11. Then, the jet can 5 placed on the rotating base 51 is opened, and the cold air stored in the air tank 52 is sprayed out through the jet nozzle 53. Then, the oil nozzle 41 sprays the lubricating oil stored in the oil tank 42 of the oil spraying barrel 4 onto the surface of the workpiece and the processing channel 11. Then, the push cylinder 31 is driven to push the push rod 32 to push the workpiece onto the processing channel 11. When the workpiece moves to the processing channel, the bending plate 12 with a suitable angle is placed at the bending point. At the same time, the drive motor 21 on the positioning block 2 drives the angle, and the positioning block 22 is pressed down onto the upper surface of the workpiece by the positioning cylinder 23. Then, the workpiece is pushed to complete the bending.
