Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically a centering clamping type steel structure bending machine. Background Technology

[0002] A bending machine is a machine capable of bending thin plates. Its main structure includes a support frame, a worktable, and a clamping plate. The worktable is placed on the support frame and consists of a base and a pressure plate. The base is connected to the clamping plate via a hinge. The base comprises a housing, a coil, and a cover plate. The coil is placed within a recess in the housing, and the top of the recess is covered by the cover plate. In steel structure processing, it is frequently necessary to bend steel to meet the needs of different projects.

[0003] Currently, existing bending machines have certain shortcomings when processing steel structures: During the clamping and bending process, existing bending machines generally use symmetrical bending dies to ensure the workpiece is subjected to uniform force and automatically centered when clamped. However, during the centering and clamping of the steel structure, its two ends inevitably change position. Since the two ends of the steel structure are fixed, this causes wear on the steel structure, affecting the bending process and results. Therefore, there is an urgent need to design a centering clamping type steel structure bending machine to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a centering clamping steel structure bending machine to solve the problems mentioned in the background art.

[0012] Furthermore, the adjustment assembly includes four limiting slots on the workbench and the top of the equipment box, and movable blocks passing through the limiting slots are fixed on both sides of the bottom of the two movable seats. The bottom of each movable block is rotatably connected to a connecting rod. One end of two adjacent connecting rods is rotatably connected to the same push-pull seat. A synchronous hydraulic cylinder for adjusting the position of the push-pull seat is installed on the top inner wall of the equipment box.

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.

[0029] Please see Figures 1-6 In this embodiment of the utility model, a centering clamping type steel structure bending machine includes: a bending machine body and an equipment box 1 installed on the bending machine body. The bending machine body includes a frame 2 installed on the equipment box 1, and the top of the frame 2 is rotatably connected to the same rotating bracket 5. One end of the rotating bracket 5 is rotatably connected to one end of the frame 2 with a hydraulic cylinder 4. The other end of the rotating bracket 5 is rotatably connected to a lifting plate 6, and one end of the lifting plate 6 is slidably engaged with the other end of the frame 2. A bending knife 7 is installed at the bottom of the lifting plate 6, and the bending knife 7 is located above the center of the cutting groove 18.

[0030] Workbench 9 is installed on the top of equipment box 1, and a cutting groove 18 is provided in the middle of the top of workbench 9;

[0031] Two movable seats 8 are symmetrically distributed on the worktable 9 with the cutting groove 18 as the center.

[0032] An adjustment assembly, located inside the equipment box 1, is used to adjust the distance between the two movable seats 8. The adjustment assembly includes four limiting slots 12 on the workbench 9 and the top of the equipment box 1. Movable blocks 14 passing through the limiting slots 12 are fixed on both sides of the bottom of the two movable seats 8. Connecting rods 15 are rotatably connected to the bottom of each movable block 14. One end of each of the two adjacent connecting rods 15 is rotatably connected to the same push-pull seat 17. A synchronous hydraulic cylinder 13 for adjusting the position of the push-pull seat 17 is installed on the top inner wall of the equipment box 1. A hydraulic system 3 is provided at one end of the frame 2, and hydraulic cylinder 4 and synchronous hydraulic cylinder 13 are connected to the hydraulic system 3. The synchronous hydraulic cylinder 13 in the adjustment assembly pushes the push-pull seat 17 to move, and the connecting rods 15 drive the movable seats 8 to slide along the limiting slots 12 on the workbench 9, ensuring that the two movable seats 8 simultaneously and equally approach or move away from the cutting groove 18, thereby accurately adjusting the clamping position of steel structures of different widths and always keeping the steel structure in the center position of the equipment for clamping.

[0033] Each of the two movable seats 8 has a semi-circular groove 21 on one side, and a clamping seat 10 is movably installed on the inner wall of the semi-circular groove 21. The inner wall of the semi-circular groove 21 has equally spaced arc-shaped grooves 22, and the surface of the clamping seat 10 is equipped with multiple sliders 23 inserted into the arc-shaped grooves 22. The bottom of the sliders 23 and the bottom inner wall of the arc-shaped grooves 22 are equipped with a first spring 24. The cross-section of the sliders 23 and the cross-section of the arc-shaped grooves 22 are designed to be T-shaped. The opposite sides of the two clamping seats 10 have right-angle grooves 26 for placing steel structures. The bottom of the right-angle grooves 26 has equally spaced strip grooves, and the inner wall of each strip groove is rotatably connected to a support roller 27. A buffer component is provided on one side of each right-angle groove 26, so that the clamping seat 10 can better fit the surface of steel structures of different shapes, enhance the clamping effect, and make the entire clamping area better adapt to the deformation of the steel structure, avoiding wear at both ends of the steel structure.

[0034] Specifically, guide rods 19 are fixed to the inner walls of the limiting grooves 12, and guide holes for the guide rods 19 to pass through are provided on the movable blocks 14. First slide grooves 20 are provided at both ends of the bottom of the two movable seats 8, and a first slide rail 11 that fits against the inner wall of the first slide groove 20 is installed on the top of the worktable 9. A second slide groove is provided on the top of the push-pull seat 17, and a second slide rail 16 that fits against the second slide groove is installed on the inner wall of the top of the equipment box 1. Through the cooperation of the guide rods 19 with the guide holes, the cooperation of the first slide groove 20 with the first slide rail 11, and the cooperation of the second slide groove with the second slide rail 16, good guidance is provided for the movement of the movable seats 8 and the push-pull seat 17, improving the stability of the equipment during operation and reducing shaking and deviation.

[0035] Specifically, the buffer assembly includes a buffer groove 25 opened on one side of the right-angle groove 26, and a buffer seat 28 is inserted into the inner wall of the buffer groove 25. Second springs 29 are installed at equal distances on one side of the buffer seat 28 and the inner wall of the buffer groove 25. The buffer assembly can absorb impact force during clamping and processing, further protect the steel structure from damage, and improve the reliability of processing.

[0036] The working principle of this utility model is as follows: The steel structure to be bent is placed in the right-angle groove 26 between two clamping seats 10. The bottom of the steel structure is supported by the support roller 27. According to the width of the steel structure, the synchronous hydraulic cylinder 13 is activated. The synchronous hydraulic cylinder 13 pushes the push-pull seat 17 to move. The push-pull seat 17 drives the movable block 14 and the movable seat 8 to slide along the limiting groove 12 on the worktable 9 through the connecting rod 15. The distance between the two movable seats 8 is adjusted so that the clamping seat 10 clamps the steel structure at the center position directly above the cutting groove 18. At the same time, the clamping seat 10 slides in the arc groove 22 through the slider 23 and adaptively fits the surface of the steel structure under the action of the first spring 24. The buffer seat 28 in the buffer assembly also provides a certain buffer and adaptive clamping force to the side of the steel structure under the action of the second spring 29.

[0037] Then, the hydraulic cylinder 4 is started, pushing the rotating bracket 5 to rotate around its rotating connection point with the frame 2. The rotating bracket 5 drives the lifting plate 6 to slide down along one side of the frame 2. The bending blade 7 at the bottom of the lifting plate 6 then descends. Since the bending blade 7 is located above the center of the cutting groove 18, and the steel structure has been accurately centered and clamped above the cutting groove 18, the bending blade 7 can perform a precise bending operation on the steel structure. During the bending process, the support roller 27 can reduce the friction between the steel structure and the bottom of the right angle groove 26, and synchronously drive the clamping seat 10 to rotate when the positions of the two ends of the steel structure change, so that the entire clamping area can better adapt to the deformation of the steel structure, making it easier for the steel structure to rotate and deform to a certain extent during bending.

[0038] After bending is completed, hydraulic cylinder 4 retracts, driving rotating bracket 5 and lifting plate 6 to rise, causing bending knife 7 to leave the steel structure. Then, synchronous hydraulic cylinder 13 moves in the opposite direction, driving movable seat 8 to move away from each other, releasing the clamp on the steel structure, and the bent steel structure can be taken out.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
