Description

Technical Field

[0001] The utility model relates to an H-shaped steel welding mechanism. Background Art

[0002] The H-beam production line includes an assembly station, a plurality of welding stations, and a correction station arranged in sequence. The web plate and two wing plate plates are preliminarily assembled and formed at the assembly station, then welded at the welding station, and finally corrected at the correction station. A welding mechanism is provided at the welding station. For example, in CN 212496195 U, the welding mechanism of the H-beam high-efficiency production line includes an input roller and an output roller. The H-beam is input from the input roller, transferred to the welding gun by a feeding trolley for welding, and the workpiece is flipped by an automatic flipping mechanism to realize automatic adjustment of the welding posture. After the welding machine is completed, it is transferred to the conveying roller for output by the feeding trolley. The disadvantages that still exist are: the production is carried out in a fully automatic manner, but the cost is relatively high; although fully automated production is achieved, the replacement of the workpiece during production or process requires relatively complicated procedures, and its welding efficiency still has room for improvement. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings of the existing H-beam welding mechanism, the utility model provides an H-beam welding mechanism with low cost and high welding efficiency.

[0004] The utility model solves the technical problem by providing a technical solution: an H-beam welding mechanism comprises a longitudinally arranged conveying roller, and welding devices are respectively arranged on both sides of the conveying roller, and the welding devices comprise:

[0005] A tire frame parallel to the conveying roller, the tire frame having a placing surface, and the H-beam workpiece is placed on the placing surface in a boat-shaped welding posture;

[0006] A vertical frame located outside the tire frame, the vertical frame being provided with a longitudinal drive mechanism and a longitudinal guide rail parallel to the tire frame;

[0007] A longitudinal moving frame slidably disposed on the guide rail, the longitudinal moving frame being connected to the longitudinal moving driving mechanism so that the longitudinal moving frame can move longitudinally along the longitudinal guide rail under the drive of the longitudinal moving driving mechanism;

[0008] A welding gun is arranged on the longitudinal moving frame.

[0009] Furthermore, the longitudinal moving frame is provided with a transverse track, a transverse moving frame is slidably provided on the transverse track, and the welding gun is provided on the transverse moving frame;

[0010] The longitudinal moving frame is also provided with a transverse moving driving mechanism, and the transverse moving frame is connected to the transverse moving driving mechanism so that the transverse moving frame can move transversely along the transverse track under the drive of the transverse moving driving mechanism.

[0011] Furthermore, the two sides of the tire frame are respectively provided with a placing surface, so that one tire frame can place two H-shaped steel workpieces; two groups of welding guns are arranged on the transverse frame, and the two groups of welding guns correspond to the two placing surfaces of one tire frame respectively.

[0012] When the utility model is in use, the H-shaped steel workpiece is input from the conveyor roller. During welding, the H-shaped steel component needs to be hoisted to the shelf surface of the tire frame by a crane, and then the welding gun is used to perform a boat-shaped welding operation on the butt joint of the web and the wing. During welding, the four butt joints on the front and back sides of the web and wing of the H-shaped steel component need to be welded. After each weld seam is welded, the H-shaped steel component needs to be hoisted by a crane to adjust its posture for boat-shaped welding. After welding is completed, the welded H-shaped steel component is hoisted to the conveyor roller by a crane and transported forward.

[0013] The beneficial effects of the utility model are as follows: when the H-shaped steel workpiece is transferred from the conveyor roller to the welding device for welding, a fully automatic mechanism is no longer used, thereby reducing the production cost; a conveyor roller is provided between the welding station and the workpiece, and the conveying of the workpiece is smoother; welding devices are provided on both sides of the conveyor roller, and the welding efficiency is higher.

[0017] A tire frame 3 is parallel to the conveying roller 1, and the tire frame 3 has a placing surface 4. After the H-beam workpiece is placed on the placing surface 4, it is in a boat-shaped welding posture.

[0018] A vertical frame 5 is located outside the tire frame 3 , and the vertical frame 5 is provided with a longitudinal driving mechanism and a longitudinal guide rail parallel to the tire frame 3 .

[0019] The longitudinal moving frame 6 is slidably arranged on the guide rail, and the longitudinal moving frame 6 is connected to the longitudinal moving driving mechanism so that the longitudinal moving frame 6 can move longitudinally along the longitudinal guide rail under the drive of the longitudinal moving driving mechanism. The longitudinal moving driving mechanism can be a gear rack mechanism, a drag chain mechanism, etc.

[0020] The welding guns 7 disposed on the longitudinal moving frame 6 have no limitation on the number of welding guns 7 , and may be one welding gun, or two welding guns or more welding guns.

[0021] When in use, the H-shaped steel workpiece is input from the conveyor roller 1. When welding, the H-shaped steel component needs to be hoisted to the shelf surface 4 of the tire frame 3 by a crane, and then the welding gun 7 is used to perform a boat-shaped welding operation on the butt joint of the web and the wing. When welding, it is necessary to weld the four butt joints on the front and back sides of the web and wing of the H-shaped steel component. After each weld, the H-shaped steel component needs to be hoisted by a crane to adjust its posture for boat-shaped welding. After welding is completed, the welded H-shaped steel component is hoisted to the conveyor roller 1 by a crane and transported forward.

[0022] In one embodiment, the longitudinal moving frame 6 is provided with a transverse track, a transverse moving frame 8 is slidably arranged on the transverse track, and the welding gun 7 is arranged on the transverse moving frame 8; the longitudinal moving frame 6 is also provided with a transverse moving drive mechanism, and the transverse moving frame 8 is connected to the transverse moving drive mechanism so that the transverse moving frame 8 can move laterally along the transverse track under the drive of the transverse moving drive mechanism, and at this time the welding gun 7 can move laterally to adapt to H-shaped steel components of different sizes.

[0023] In one embodiment, the two sides of the tire frame 3 are respectively provided with a placement surface 4, so that one tire frame 3 can place two H-beam workpieces; the transverse frame 8 is provided with two sets of welding guns 7, and the two sets of welding guns correspond to the two placement surfaces of one tire frame. At this time, during welding, the two H-beam components are hoisted to the two placement surfaces 4 by the crane, and the web and wing joints of the H-beam are welded by the two sets of welding guns. When welding devices 2 are respectively provided on both sides of the conveyor roller 1, four H-beam workpieces can be welded at the same time in one welding station, which greatly improves the efficiency.
