Description

Technical Field

[0001] The utility model relates to the technical field of H-beam correction equipment, in particular to a correction device used for H-beam assembly welding. Background Art

[0002] The welding deformation of H-beam is mainly caused by the thermal stress and residual stress generated during the welding process. This deformation will seriously affect the performance of H-beam and may even cause structural instability. For example, after the H-beam is welded, its flange will bend inward or outward, and the existing flange correction mechanism is usually an upper and lower roller mechanism, which cooperates with the hydraulic system on the roller mechanism to squeeze the H-beam flange; however, this method of hydraulic mechanical correction from the upper and lower surfaces of the H-beam has some defects. Since the correction force output by the correction mechanism is from the upper and lower surfaces, it can only be used for H-beams with flanges bent outward.

[0003] Secondly, some existing correction mechanisms can solve the problem of limited correction range, such as using three rollers to synchronously clamp the flange of the H-beam, but in this way, after correcting one side of the flange, it is necessary to correct the flange on the other side again. Therefore, those skilled in the art hereby propose a correction device for H-beam assembly welding. Utility Model Content

[0023] Embodiment, a better technical solution for a correction device for H-beam assembly welding.

[0024] Including the following: Refer to the instruction manual Figure 1 As shown; it includes three conveyor support legs 1 and two brackets 2, a roller conveyor 6 is fixed on the top surface of the conveyor support leg 1, a roller frame 5 is movably provided on the upper surface of the roller conveyor 6, and an H-beam material 4 is clamped and transported on the side where the roller frame 5 and the roller conveyor 6 are close to each other; an H-beam flange correction component 3 is fixed on the top surface of the bracket 2, and the H-beam material 4 passes through the internal gap of the H-beam flange correction component 3.

[0025] Refer to the instruction manual Figure 2 As shown; the H-beam flange correction assembly 3 includes a left-right symmetrical L-shaped bent rod 31, which passes through and is fixed in the middle column 32 inside the L-shaped bent rod 31, and a hydraulic cylinder 37 which is symmetrically arranged at the upper and lower ends of the middle column 32, and the hydraulic telescopic rod of the hydraulic cylinder 37 is fixedly connected to a pressure block 38, a bearing 39 is fixed to the bottom surface of the pressure block 38, and an upper pressure roller 310 is rotatably connected inside the bearing 39.

[0026] Refer to the instruction manual Figure 2 As shown; two movable blocks 34 are movably sleeved on the upper and lower outer ring surface of the middle column 32, and the side of the movable block 34 close to the H-shaped steel material 4 is rotatably connected with the lower pressure roller 311; wherein, the lower pressure roller 311 and the upper pressure roller 310 are in contact with the flange surface of the H-shaped steel material 4 when they are close to each other; the upper and lower ends of the middle column 32 are fixed with a base 35, and the upper surface of the base 35 is fixed with a guide rail 36 at the front and rear positions, and the end of the guide rail 36 away from the base 35 passes through the pressure block 38 and is fixedly connected to the front and rear side walls of the hydraulic cylinder 37. A screw rod 33 is passed through the inner front side of the movable block 34, and four nuts are locked on the outer ring of the screw rod 33, and the side of the nuts close to each other contacts the upper and lower surfaces of the movable block 34.

[0027] Refer to the instruction manual Figure 1 As shown; the rear side wall of the bracket 2 is fixedly connected to the front side end face of the roller conveyor 6. The bottom surface of the L-shaped bent rod 31 is locked with the top surface of the bracket 2 by bolts. Figure 3 As shown; convex strips are fixed on the left and right sides of the upper surface of the roller conveyor 6 and the left and right sides of the upper surface of the roller frame 5.

When the bracket 2 and the conveyor support foot 1 are at the same height and the flange of the H-beam material 4 can pass through the gap between the upper pressure roller 310 and the lower pressure roller 311, the nut closest to the outer position on the screw rod 33 is screwed to a position away from the movable block 34, and the nut closest to the middle position is screwed with a wrench tool to push the movable blocks 34 away from each other, thereby forcing the lower pressure roller 311 to expand the flange of the H-beam material 4 in the up and down directions. At this time, the hydraulic cylinder 37 controls the pressing block 38 to move synchronously to pull the upper pressing roller 310 toward the upper and lower surfaces of the H-beam material 4, and until the upper pressing roller 310 contacts the upper and lower surfaces of the H-beam material 4. After the outer ring surfaces of the lower pressing roller 311 and the upper pressing roller 310 are kept parallel to the flange of the H-beam material 4, the H-beam material 4 passes through the gap between the lower pressing roller 311 and the upper pressing roller 310, thereby correcting and straightening the flange.

It is undoubted that 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.
