[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model discloses a bending device for steel structure production.
[0025] This utility model provides a bending device for steel structure production, as shown in Figures 1-3, including a bending base 1. The device is characterized in that a support plate 2 is fixedly provided at the lower end of the inner wall of the bending base 1. First rotating grooves 3 are provided on both sides of the support plate 2. A rotating rod 4 is rotatably provided within the first rotating grooves 3. A push plate 5 is fixedly sleeved on the rod wall of the rotating rod 4. A pushing bending mechanism for driving the push plates 5 is provided at the lower end of each push plate 5. The pushing bending mechanism includes a hydraulic cylinder 11, which is fixedly located at the bottom of the inner wall of the bending base 1. A connecting block 12 is rotatably provided at the end of the output shaft of the hydraulic cylinder 11 via a shaft pin. A guide frame 13 slides through the interior of the connecting block 12. The guide frame 13 is a U-shaped guide frame and is fixedly located at the bottom of the push plate 5.
[0026] An electric push rod 6 is fixedly installed on the top of the inner wall of the bending base 1. A positioning frame 7 is fixedly installed at the end of the output shaft of the electric push rod 6. The positioning frame 7 is U-shaped and has chamfered angles on both sides of the lower end. A second rotating groove 8 is opened on both sides of the lower end of the positioning frame 7. A crossbar 9 is rotatably passed through the second rotating groove 8. A positioning plate 10 is fixedly sleeved on the wall of the crossbar 9. An angle indicator 17 is fixedly installed on the outer wall of the positioning frame 7.
[0027] In order to quickly adjust the setting angle of the positioning plate 10 according to the bending requirements and thus control the bending angle, as shown in Figures 1-3, an angle adjustment mechanism for adjusting the rotation angle of the positioning plate 10 is provided between the two positioning plates 10. The angle adjustment mechanism includes an adjusting screw 14, an mounting plate 15 is fixedly provided on the upper side of the inner wall of the positioning frame 7, the adjusting screw 14 is rotatably disposed in the mounting plate 15, and a slider 16 is threadedly sleeved on the rod wall. A fixing plate 18 is fixedly provided on the side of the mounting plate 15 near the adjusting screw 14. Support rods 19 are fixedly inserted inside both the slider 16 and the fixing plate 18. A connecting plate 20 is rotatably sleeved between two adjacent support rods 19, and a rotating block 21 is fixedly provided on the top of the adjusting screw 14.
[0028] Operating method: First, place the steel structure to be bent on the support plate 2. Adjust the angle adjustment mechanism according to the required bending angle. By rotating the rotating block 21, the adjusting screw 14 will be rotated. Since the adjusting screw 14 is threadedly connected to the slider 16, and the slider 16 is connected to the fixed plate 18 through the support rod 19 and the connecting plate 20, when the adjusting screw 14 is rotated, the slider 16 will move along the axial direction of the adjusting screw 14. As the slider 16 moves, the connecting plate 20 will drive the support rod 19 connected to it to change position, thereby causing the positioning plate 10 fixed on the crossbar 9 to rotate around the crossbar 9. The included angle between the two positioning plates 10 will change accordingly. During the adjustment process, the required angle of the positioning plate 10 can be accurately adjusted by observing the angle indicator 17 on the outer wall of the positioning frame 7.
[0029] After the angle adjustment is completed, start the electric push rod 6. The output shaft of the electric push rod 6 extends and pushes the positioning frame 7 downward to make the positioning plate 10 close to the steel structure. When the positioning plate 10 contacts the steel structure, stop the electric push rod 6.
[0030] Next, the hydraulic cylinder 11 in the bending mechanism is activated. The output shaft of the hydraulic cylinder 11 extends and drives the connecting block 12 to move through the shaft pin. Since the guide frame 13 is fixed to the bottom of the push plate 5 and slides inside the connecting block 12, the movement of the connecting block 12 drives the guide frame 13 and the push plate 5 to rotate along the rotating rod 4. The push plate 5 gradually moves closer to the steel structure and applies a pushing force to it. During the process of the push plate 5 pushing the steel structure, the steel structure will be restricted by the positioning plate 10 and bend according to the angle set by the positioning plate 10.
[0031] After bending is completed, first retract the output shaft of the hydraulic cylinder 11 to drive the push plate 5 back to the initial position, then start the electric push rod 6 to raise the positioning frame 7 and remove the positioning plate 10 from the bent steel structure. Finally, take out the bent steel structure to complete one bending operation. If bending work at different angles is required, repeat the above steps of adjusting the angle and bending.
[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
