Description

Technical Field

[0001] This utility model relates to the field of steel structure manufacturing technology, and in particular to an integrated automatic welding and straightening machine for H-beams. Background Technology

[0002] H-beams are made up of two flanges and a central web. The H-beam automatic welding and straightening integrated machine combines traditional welding and straightening into one, integrating the work that originally required multiple machines on a traditional assembly line into one, thereby improving production efficiency and product qualification rate, reducing production costs, and saving space. The steps are to first connect one flange to the web to weld it into an inverted T shape, and then turn it over and weld it into an H shape.

[0003] The existing equipment has a relatively simple correction mechanism. When welding H-beams, it lacks correction support for the upper flange. As a result, when the upper flange is large, the existing correction mechanism is not stable enough and there is room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of correction support for the upper flange, which makes the existing correction mechanisms relatively unstable when the upper flange is large. Therefore, this invention proposes an integrated automatic welding and correction machine for H-beams.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic welding and straightening machine for H-beams includes a base, in which multiple rollers are rotatably arranged;

[0007] A welding mechanism is used to weld H-beam steel components, the H-beam steel including two flanges and a web between the two flanges. The welding mechanism is located on the top of the base and includes two welding guns, each of which is fixedly mounted on one end of the top of the base by a bracket.

[0008] A correction mechanism is used to correct and limit the H-beam steel components. The correction mechanism is set on the top of the base and includes two auxiliary rollers. A gantry frame is fixedly set on the top of the base. Outer cylinders are slidably set on the inner walls of both sides of the gantry frame. An inner rod is slidably set inside the outer cylinder. A U-shaped frame is rotatably set on one end of the inner rod. The two auxiliary rollers are respectively rotatably set in the two U-shaped frames. The auxiliary rollers cooperate with the bottom of the upper flange and the side of the web.

[0009] In one possible design, the correction mechanism further includes a square block, with a first square groove and a second square groove respectively opened on the side of the inner rod and the U-shaped frame that are close to each other. One end of the square block is slidably disposed inside the first square groove, and the other end slides into the inside of the second square groove. A connecting rod is fixedly disposed on one side of the square block and passes through the U-shaped frame. A threaded rod is rotatably disposed on the other side of the square block, and the threaded rod is threaded through the inner rod.

[0010] In one possible design, the inner rod has an inner cavity that is connected to a square groove. A sliding plate is slidably disposed inside the inner cavity, and one end of the sliding plate is fixedly disposed on one side of the square block. An insertion rod is fixedly disposed on one side of the sliding plate, and one end of the insertion rod slides through the inner rod. The outer cylinder has multiple insertion holes on one side, and all the insertion holes are matched with the insertion rod.

[0011] In one possible design, upright plates are fixedly installed on both inner walls of the base, and multiple horizontal limiting grooves are opened on one side of the upright plates, and the multiple horizontal limiting grooves cooperate with the insertion rod.

[0012] In one possible design, the correction mechanism further includes at least two first-side rollers, two second-side rollers, and two first-upper rollers. The two first-side rollers are respectively mounted on both sides of the top of the base via brackets, and each first-side roller engages with both sides of the lower flange. The two second-side rollers are respectively mounted on both sides of the top of the base via brackets, and each second-side roller engages with both sides of the web. The two first-upper rollers are respectively mounted on both sides of the top of the base via brackets, and each first-upper roller engages with both sides of the top of the lower flange.

[0013] In one possible design, the bottom inner wall of the gantry is provided with a second upper roller via a bracket, and the second upper roller engages with the top of the upper flange.

[0014] In one possible design, the outer wall of the second upper roller is provided with an annular groove, and the cross-section of the annular groove is V-shaped, and the annular groove is matched with the top of the web plate.

[0015] In this application, during actual use, the lower flange of the steel is conveyed to the rollers at the top of the base via a conveyor or other conveying mechanism. The web is placed on top of the lower flange, and the lower flange is limited by two No. 1 side rollers to ensure stable conveying. The No. 1 upper roller presses down on the top of the lower flange, and the web is conveyed by two No. 2 side rollers. The No. 2 upper roller at the top limits the top of the web of the inverted T-shaped steel through a V-shaped annular groove, achieving the effect of initial limiting and correction from the door, ensuring stable welding later. Welding work can be carried out at the connection between the lower flange and the web through welding guns on both sides. For H-shaped steel, the No. 2 upper roller fits against the top of the upper flange through its outer wall surface, thus cooperating in use.

[0016] When welding inverted T-shaped steel, the threaded rod can be rotated, causing the square block to move. One end of the square block disengages from the second square slot and enters the first square slot. At this point, the U-shaped frame is released from its fixed state, allowing the auxiliary roller to rotate and support the side of the web plate. The movement of the square block also moves the insert rod via the sliding plate, disengaging it from the insertion hole and the transverse limiting slot. The outer cylinder can then slide, and the inner rod can extend and retract, facilitating adjustment of the auxiliary roller's position. Afterward, simply reverse the threaded rod to re-engage one end of the square block into the second square slot, thus fixing the U-shaped frame. The insert rod will also move, re-engaging with the corresponding insertion hole and transverse limiting slot, thus re-fixing the inner rod and outer cylinder. When welding H-shaped steel, the same operation is performed, rotating the auxiliary roller upwards and supporting it against the bottom of the upper flange (e.g., Figure 2 ).

[0017] In this utility model, the automatic welding and straightening integrated machine for H-beams can adjust and support the welding process of H-beams at different stages through the auxiliary rollers of the straightening mechanism. This allows for the support and straightening of the upper flange while also adjusting and increasing the support for the web, thus solving the original problems and increasing its practicality.

[0018] In this utility model, the automatic welding and straightening integrated machine for H-beams, through the welding mechanism and the straightening mechanism, can realize the automatic welding and straightening functions of H-beams, which greatly improves production efficiency and reduces production costs.

[0019] In this invention, by adjusting the auxiliary rollers to different positions, the H-shaped steel and the initial inverted T-shaped steel can be supported and corrected accordingly. This solves the problem of the lack of support and correction effect on the upper flange in existing designs, while allowing for free adjustment and increasing its practicality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1 A welding and straightening integrated machine includes: multiple rollers rotatably arranged inside the base to facilitate the subsequent movement of steel materials; and a welding mechanism and a straightening mechanism are provided on the top of the base 1.

[0029] The welding mechanism includes two welding guns 2, which are fixedly mounted on one end of the top of the base 1 via brackets. The welding guns 2 are used to weld the joints between the flanges and the web of the H-beam.

[0030] The alignment mechanism is used to align and limit the welded H-beams. The mechanism includes a first side roller 3, a second side roller 4, and a first upper roller 5. Both first side rollers 3 are mounted on both sides of the top of the base 1 via brackets and engage with both sides of the lower flange of the H-beam. Similarly, both second side rollers 4 are mounted on both sides of the top of the base 1 via brackets and engage with both sides of the web of the H-beam. The two first upper rollers 5 are mounted on both sides of the top of the base 1 via brackets and engage with both sides of the top of the lower flange of the H-beam.

[0031] A gantry frame 8 is fixedly installed on the top of the base 1. A second upper roller 7 is also installed on the bottom inner wall of the gantry frame 8 via a bracket. The second upper roller 7 mates with the top of the upper flange of the H-beam. An annular groove is also provided on the outer wall of the second upper roller 7. The cross-section of the annular groove is V-shaped and mates with the top of the web of the H-beam.

[0032] Specifically, the lower flange of the steel is conveyed to the rollers on the top of the base 1 by a conveyor or other conveying mechanism. The web is placed on top of the lower flange. The lower flange will be limited by two No. 1 side rollers 3 to ensure stable conveying, and the No. 1 upper roller 5 will press down on the top of the lower flange. The web will be limited by two No. 2 side rollers 4 for conveying. The No. 2 upper roller 7 at the top will limit the top of the web of the inverted T-shaped steel through a V-shaped annular groove, achieving the effect of initial limit correction from the door, ensuring stable welding later. Welding work can be carried out at the connection between the lower flange and the web by welding guns 2 on both sides. For H-shaped steel, the No. 2 upper roller will fit against the top of the upper flange through the outer wall surface for cooperative use.

[0033] This application can be used in the field of steel structure manufacturing, or in other fields applicable to this application.

[0034] Example 2

[0035] refer to Figure 2-3 An improvement upon Example 1: An integrated automatic welding and straightening machine for H-beams, applied in the steel structure manufacturing field. The straightening mechanism further includes two auxiliary rollers 6. Outer cylinders 10 are slidably mounted on the inner walls of both sides of the gantry frame 8, and inner rods 11 are slidably mounted inside the outer cylinders 10. A U-shaped frame 9 is rotatably mounted on one end of one side of the inner rod 11, and the two auxiliary rollers 6 are rotatably mounted within the two U-shaped frames 9 respectively. By adjusting the auxiliary rollers 6, they can cooperate with the bottom of the upper flange or the side of the web of the H-beam to straighten and limit the H-beam.

[0036] Reference Figure 4The correction mechanism also includes a square block 13, a connecting rod 14, and a threaded rod 12. A first square groove 16 and a second square groove 15 are respectively formed on the side of the inner rod 11 and the U-shaped frame 9 that are close to each other. One end of the square block 13 is slidably disposed inside the first square groove 16, and the other end slidably extends into the second square groove 15. The connecting rod 14 is fixedly disposed on one side of the square block 13 and passes through the U-shaped frame 9. The threaded rod 12 is rotatably disposed on the other side of the square block 13 and is threaded through the inner rod 11.

[0037] Reference Figure 5 The inner rod 11 has an inner cavity 17 that communicates with the first square groove 16. A sliding plate 22 is slidably disposed inside the inner cavity 17, with one end of the sliding plate 22 fixedly disposed on one side of the square block 13. An insertion rod 21 is also fixedly disposed on one side of the sliding plate 22, with one end of the insertion rod 21 slidably penetrating the inner rod 11. The outer cylinder 10 has multiple insertion holes 20 on one side, each of which mates with the insertion rod 21.

[0038] Specifically, when the equipment welds the inverted T-shaped steel, the threaded rod 12 can be rotated, which will cause the square block 13 to move, so that one end of the square block 13 disengages from the second square groove 15 and enters the interior of the first square groove 16. At this time, the U-shaped frame 9 will be released from its fixed state, thereby rotating the auxiliary roller 6, so that the auxiliary roller 6 supports and limits the side of the web plate. When the square block 13 moves, it will drive the insertion rod 21 to move through the sliding plate 22, so that the insertion rod 21 disengages from the insertion hole 20 and the transverse limiting groove 19. At this time, the outer cylinder 10 can... The sliding inner rod 11 can be extended and retracted, facilitating the adjustment of the position of the auxiliary roller 6. Then, simply rotate the threaded rod 12 in the reverse direction so that one end of the square block 13 re-engages with the interior of the second square groove 15, thus fixing the U-shaped frame 9. The insertion rod 21 will also move and re-engage with the corresponding insertion hole 20 and horizontal limiting groove 19, thus re-fixing the inner rod 11 and outer cylinder 10. When the equipment needs to weld H-shaped steel, simply perform the same operation, rotating the auxiliary roller 6 upwards and supporting and limiting it against the bottom of the upper flange (e.g., Figure 2 ).

[0039] However, as is well known to those skilled in the art, the working principle and wiring method of the welding gun 2 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
