Description

Technical Field

[0001] The utility model relates to the technical field of angle steel straightening, in particular to a straightening device for angle steel production. Background Technique

[0002] Angle steel, commonly known as angle iron in the industry, is a long strip of steel with two sides forming a right angle. Its material is usually ordinary carbon structural steel and low alloy steel. The angular structure gives it good supporting strength. Under the same supporting strength, angle steel is lighter in weight, consumes less materials, saves costs, is more flexible in construction, and occupies less space. Due to its high cost performance, angle steel is widely used in many fields such as building construction, bridges, tunnels, wire towers, ships, brackets, steel structures, etc., playing a role in supporting or fixing structures.

[0003] After the production of angle steel is completed, if it is subjected to extrusion or a large temperature difference, it is often prone to distortion and possible changes in the angle of the angle steel. In the cross-sectional direction, bending or tensile deformation may also occur due to uneven stress, and it needs to be corrected to be repaired and put into later use. Traditional angle steel straightening machines cannot well adapt to different sizes of angle steel, and there are also correction blind spots in the repair positions, with great limitations.

[0017] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0018] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: As shown in Figure 1 and Figure 2 , a straightening device for angle steel production includes: a rectangular platform 1 and a support structure 2. The support structure 2 is provided on the lower surface of the rectangular platform 1. A moving device 3 is provided on one side of the support structure 2, and the moving device 3 is connected to the support structure 2 through a connecting block 4. A rectangular mounting plate 5 is provided on the upper surface of the rectangular platform 1. A pair of symmetric rectangular blocks 6 are provided on the upper surface of the rectangular mounting plate 5, and the pair of rectangular blocks 6 are fixed to the rectangular mounting plate 5.

[0019] As shown in Figure 2 , corresponding grooves 7 are respectively formed through the vertical surfaces of the pair of rectangular blocks 6, and stoppers 8 are respectively installed on the upper surfaces of the rectangular blocks 6.

[0020] As shown in Figure 2 , a trapezoidal block 9 is provided on the upper surface of the rectangular mounting plate 5, and the trapezoidal block 9 is fixedly connected to the rectangular mounting plate 5. A trapezoidal moving block 10 is also provided on the upper surface of the rectangular mounting plate 5. The trapezoidal moving block 10 is slidably connected to the rectangular mounting plate 5, and a chute is also formed at the intersection of the rectangular mounting plate 5 and the trapezoidal moving block 10.

[0021] As shown in Figure 1 and Figure 2 , a U-shaped mounting frame 11 is provided on the upper surface of the rectangular mounting plate 5. A hydraulic telescopic rod 12 is provided on the vertical surface of the U-shaped mounting frame 11 away from the trapezoidal moving block 10. The hydraulic telescopic rod 12 penetrates through the U-shaped mounting frame 11 and is connected to the trapezoidal moving block 10. A groove 13 is formed on the upper surface of the rectangular mounting plate 5, and a movable limiting rod 14 is provided inside the groove 13. A moving block is also provided on the lower surface of the limiting rod 14, and the moving block is connected to the hydraulic telescopic rod.

[0022] As shown in Figure 1 , Figure 3 and Figure 4As shown, the mobile device 3 includes a U-shaped block 15. A moving groove 111 is provided on the upper surface of the U-shaped block 15. A driving motor 16 is arranged inside the moving groove 111. A threaded rod 17 is arranged on the circular surface of the driving motor 16. A moving block 18 penetrated by the threaded rod 17 is arranged on the rod body of the threaded rod 17. A cylindrical hole is provided at the intersection of the moving block 18 and the threaded rod 17. A threaded groove is provided on the arc surface inside the cylindrical hole. The threaded groove is in a meshing relationship with the thread on the threaded rod 17.

[0023] As Figure 1 and Figure 4 shown, an L-shaped loading frame 19 is connected to the upper surface of the moving block 18. A hydraulic pressing device 20 is penetrated through the upper surface of the L-shaped loading frame 19. The pressing block in the hydraulic pressing device 20 is composed of two rectangular blocks. A gap is left between the two pressing blocks, which can ensure that the vertical part of the L-shaped angle steel will not be affected by the pressing.

[0024] Working principle: When the device is working, first place the L-shaped angle steel on the rectangular mounting plate 5 by means of a robotic arm or manually. At this time, the position of the angle steel is such that the inner ring of the angle steel is in contact with the corresponding groove 7 and the upper surface of the rectangular block 6. Then start the hydraulic telescopic rod 12. At this time, because the hydraulic telescopic rod 12 penetrates the U-shaped mounting frame 11 and is connected to the trapezoidal moving block 10, the trapezoidal moving block 10 will move towards the position of the angle steel and finally clamp the angle steel. Then start the hydraulic pressing device 20. At this time, the L-shaped loading frame 19 is directly above the trapezoidal moving block 10 and does not need to move. After the hydraulic pressing device 20 completes the pressing, the trapezoidal moving block 10 is reset. At this time, this is only the first step. Then pick up the L-shaped angle steel by means of a robotic arm or manually and rotate it so that the vertical part of the L-shaped angle steel is above. Then place it on the upper surface of the rectangular block 6. Then start the hydraulic telescopic rod 12 and the limit rod 14 at the same time so that the two clamp the angle steel. Then, according to the degree of bending on the plane of the angle steel, start the driving motor 16 at this time, so that the moving block 18 moves. After the L-shaped loading frame 19 is directly above the position to be pressed, start the hydraulic pressing device 20 again to perform pressing and correction. If other surfaces need to be pressed, it is the same as above.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
