Description

Technical Field

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

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. They are widely used in large factories, stadiums, super high-rise buildings and other fields. In the production and processing of steel structures, it is necessary to produce steel structures of various shapes, which requires the use of bending machines.

[0003] In response to the aforementioned problem of steel structures being prone to swaying, CN219766467U discloses a bending device for steel structure processing, comprising a worktable, a fixed platform fixedly connected to the top left side of the worktable, a motor housing fixedly connected to the bottom end of the worktable, a bending platform provided on the top right side of the worktable, a fixing mechanism provided on the side of the fixed platform, and a heat dissipation mechanism fixedly connected to the side of the motor housing.

[0004] In the above scheme, the drive handle enables the drive wheel to rotate, which in turn drives the threaded rod to rotate. This causes the threaded slider to move the push rod, and the sliding block within the sliding groove allows the push rod to extend, facilitating the ejection of the fixing plate and thus securing the steel structure. This improves the fixing effect and ensures that the bending effect of the steel structure is not affected. However, this equipment is difficult to use for fixing high-strength steel, as the steel has a high springback force. The effect of using the fixing plate to eject the steel is limited. Prolonged use under load will cause the internal springs to wear and reduce their performance. To improve the clamping force on the steel, designing a bending device for steel structure processing has become an urgent problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0006] This utility model adopts the following technical solution: a bending device for steel structure processing, including a base, a mounting frame fixed on the surface of the base, a motor one fixed on the side of the mounting frame, a guide rod fixed on the output end of the motor one, a synchronous wheel one, a synchronous wheel two and a gear fixed on the surface of the guide rod, a rectangular tooth block meshing on the surface of the gear, a clamping plate fixed at one end of the rectangular tooth block, a bidirectional telescopic cylinder one fixed on the surface of the base, a fixing block two fixed on the surface of the bidirectional telescopic cylinder one, an electric telescopic rod fixed on the surface of the fixing block two, a bidirectional telescopic cylinder two fixed on the output end of the electric telescopic rod, and clamps fixed at both ends of the bidirectional telescopic cylinder two.

[0007] Preferably, an anti-slip block is fixed to the inner side of the clamping plate. Here, the anti-slip block is made of polyurethane material and is arranged at equal intervals, which can increase the friction between the high-strength steel and the clamping plate, thereby improving the clamping force of the equipment.

[0008] Preferably, the first synchronous pulley and the second synchronous pulley are connected by a synchronous belt, and a dustproof box is fitted over the surfaces of the first synchronous pulley, the second synchronous pulley, and the synchronous belt. Here, through the cooperation of the first motor, the first synchronous pulley, and the synchronous belt, the two clamping plates can move inward or outward simultaneously, allowing for the fixing of steel plates of different sizes.

[0009] Preferably, there are two sets of clamping plates, which are symmetrically distributed on the surface of the base. Here, the clamping plates further enhance the clamping effect on the steel plate, reducing the risk of detachment leading to bending errors.

[0010] Preferably, a toothed block is fixed to the surface of the clamp. Here, the toothed block can increase the friction between the steel and the clamp, further improving the clamping effect of the device.

[0011] Preferably, a second motor is fixed to the bottom of the base, a bending table is fixed to the output end of the second motor, a third motor is fixed to the surface of the bending table, a bidirectional threaded screw is fixed to the output end of the third motor, a fixing block is threadedly connected to the surface of the bidirectional threaded screw, and a bending column is fixed to the surface of the fixing block. Here, the second motor can bend the steel fixed on the bending table at different angles, which is convenient to operate. At the same time, the cooperation between the third motor and the bidirectional threaded screw can fix and limit the steel in the middle, preventing it from falling off during the bending process and causing bending errors.

[0012] Preferably, the surface of the bending column is provided with a knurled structure, a guide column is fixed inside the bending table, and a dust cover is fixed to the surface of the bending table. Here, the knurled structure can increase the friction between the bending column and the steel, maximizing the clamping effect of the bending equipment.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, through the cooperation of the motor, the synchronous pulley and the synchronous belt, the two clamping plates can move inward or outward simultaneously, which can fix steel plates of different sizes and achieve a preliminary clamping effect. The clamping effect of the equipment can be further improved by the bidirectional telescopic cylinder, the electric telescopic rod and the bidirectional telescopic cylinder.

[0015] 2. In this utility model, the distance between the two bending columns can be adjusted by the cooperation of the motor, the bidirectional threaded screw and the bending column, which can fix the bent steel and greatly improve the clamping effect of the equipment. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] Please see Figure 1-3This utility model provides a technical solution: a bending device for steel structure processing, including a base 1, a mounting frame 2 fixed to the surface of the base 1, a motor 3 fixed to the side of the mounting frame 2, a guide rod 4 fixed to the output end of the motor 3, a synchronous pulley 5, a synchronous pulley 6, and a gear 7 fixed to the surface of the guide rod 4, the synchronous pulley 5 and the synchronous pulley 6 being connected by a synchronous belt 15, and a dustproof box 26 covering the surfaces of the synchronous pulley 5, the synchronous pulley 6, and the synchronous belt 15. Through the cooperation of the motor 3, the synchronous pulley 5, and the synchronous belt 15, two clamping plates can be moved inward or outward simultaneously, allowing for the fixing of steel plates of different sizes. Rectangular tooth blocks 8 mesh with the surface of the gear 7, and a clamping plate 9 is fixed to one end of each rectangular tooth block 8. There are two sets of clamping plates 9. The clamping plates 9 are symmetrically distributed on the surface of the base 1. The clamping plates 9 further enhance the clamping effect on the steel plates and reduce the risk of bending errors caused by falling off. Anti-slip blocks 14 are fixed on the inner side of the clamping plates 9. The anti-slip blocks 14 are made of polyurethane material and are arranged at equal intervals. They can increase the friction between the high-strength steel and the clamping plates 9 and improve the clamping force of the equipment. A bidirectional telescopic cylinder 10 is fixed on the surface of the base 1. A fixing block 25 is fixed on the surface of the bidirectional telescopic cylinder 10. An electric telescopic rod 11 is fixed on the surface of the fixing block 25. A bidirectional telescopic cylinder 12 is fixed at the output end of the electric telescopic rod 11. Clamps 13 are fixed at both ends of the bidirectional telescopic cylinder 12. A toothed block 16 is fixed on the surface of the clamps 13. The toothed block can increase the friction between the steel and the clamps 13 and further improve the clamping effect of the equipment.

[0026] Example 2

[0027] Please see Figure 4 A second motor 17 is fixed to the bottom of the base 1. A bending table 18 is fixed to the output end of the second motor 17. A third motor 19 is fixed to the surface of the bending table 18. A bidirectional threaded screw 20 is fixed to the output end of the third motor 19. A fixing block 23 is threadedly connected to the surface of the bidirectional threaded screw 20. A bending column 21 is fixed to the surface of the fixing block 23. The second motor 17 can bend the steel fixed on the bending table 18 at different angles, which is convenient to operate. At the same time, the cooperation between the third motor 19 and the bidirectional threaded screw 20 can fix and limit the steel in the middle to prevent it from falling off during the bending process and causing bending errors. The surface of the bending column 21 is provided with a knurled structure. A guide column 22 is fixed inside the bending table 18. A dust cover 24 is fixed to the surface of the bending table 18. The knurled structure can increase the friction between the bending column 21 and the steel, and maximize the clamping effect of the bending equipment.

[0028] Working principle: When using this equipment, the user first needs to place the steel between the two sets of bending columns 21 and clamping plates 9, and then start motor 3. Motor 3 drives the synchronous wheel 5 and gear 7 on the guide rod 4 to rotate. The rotation of synchronous wheel 5 drives synchronous wheel 6 to rotate through synchronous belt 15. The rotation of gear 7 drives rectangular tooth block 8 to move left and right, driving the two sets of clamping plates 9 to move inward or outward. Then, start motor 17. The rotation of the bidirectional threaded screw 20 drives the bending column 21 on the fixed block 23 to move. The guide column 22 has a guiding function and can clamp the steel. Since the thickness of some steel is low, the clamping effect of the two clamping plates 9 alone is limited. The electric telescopic rod 11 can be started. The electric telescopic rod 11 drives the bidirectional telescopic cylinder 12 on the surface to move upward. Then, the bidirectional telescopic cylinder 12 can be started to control the distance between the two clamps 13. Alternatively, the bidirectional telescopic cylinder 10 can be started to control the distance between the two sets of clamps 13 according to the actual situation.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
