Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding apparatus for processing metal steel structures. Background Technology

[0002] Currently, H-beams are produced by hot rolling and welding. Welding involves using hot-rolled or controlled-rolled steel plates or strips as raw materials, which serve as the web and flanges respectively. After the web and flanges are vertically limited, they are welded and fixed at their contact vertical position using submerged arc welding.

[0003] In existing technologies, for welded H-beams, static fixing and limiting are used, and then manual or welding robotic arms are used to weld the seams.

[0004] It has the following shortcomings: static positioning combined with manual or robotic arm welding cannot form a dynamic production line processing mode, resulting in low processing efficiency and a large space requirement for processing site.

[0005] Therefore, the present invention proposes a welding device for processing metal steel structures. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a welding device for processing metal steel structures.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A welding device for processing metal steel structures includes a gantry frame and multiple sets of linearly arranged support guides for supporting components. The inner side of the gantry frame is provided with multiple sets of dynamic limiting parts for dynamically limiting the web and flange of H-beams. Each set of dynamic limiting parts consists of two sets arranged symmetrically. The inner side of one of the gantry frames is provided with two sets of symmetrical welding parts for welding the web and flange welds. The dynamic limiting part includes a support frame fixed to the inside of the gantry, a side limiting wheel rotatably disposed on the side wall of the support frame, and a bottom limiting wheel rotatably disposed at the bottom of the support frame. The support frame is also provided with a driving component for synchronously driving the side limiting wheel and the bottom limiting wheel.

[0008] Preferably, the side limiting wheel and the driving component are driven by a transmission assembly. The transmission assembly includes an adjustment frame one disposed on the side of the support frame and an adjustment frame two disposed at the bottom of the support frame. The side limiting wheel and the bottom limiting wheel are rotatably connected to the adjustment frame one and the adjustment frame two respectively by a wheel axle one. The inner wall of the support frame is also rotatably connected to a transition shaft one and a transition shaft two. The wheel axle one connecting the side limiting wheel and the transition shaft one are driven by a bevel gear set one. The transition shaft one and the transition shaft two are driven by a bevel gear set two. The transition shaft two and the wheel axle one connecting the bottom limiting wheel are driven by a bevel gear set three.

[0009] Furthermore, the driving component is an electric motor, and the output shaft of the electric motor is connected to the end of the transition shaft one via a coupling.

[0010] Based on the aforementioned scheme, the dynamic limiting part further includes adjustment components for adjusting the lateral position of the side limiting wheel and for adjusting the longitudinal position of the bottom limiting wheel.

[0011] A preferred embodiment of the aforementioned scheme is as follows: the first bevel gear set is rotatably connected to the inner wall of the first adjusting frame, and one of the bevel gears of the first bevel gear set is axially slidably connected to the outer wall of the first transition shaft; the third bevel gear set is rotatably connected to the inner wall of the second adjusting frame, and one of the bevel gears of the third bevel gear set is axially slidably connected to the outer wall of the second transition shaft.

[0012] As a further aspect of the present invention: the connection between one of the bevel gears of the first bevel gear set and the outer wall of the first transition shaft, which can only slide axially, and the connection between one of the bevel gears of the third bevel gear set and the outer wall of the second transition shaft, which can only slide axially, are both achieved through a clearance fit between a key and a keyway.

[0013] Meanwhile, one side of the adjustment frame one is rotatably connected to a connecting rod one, and the top of the adjustment frame two is rotatably connected to a connecting rod two. The other ends of the connecting rod one and the connecting rod two are rotatably connected to the same adjustment block.

[0014] As a preferred embodiment of the present invention: the side wall of the support frame is fixed with a telescopic rod by bolts, and the telescopic end of the telescopic rod is rotatably connected to the side wall of the adjusting block.

[0015] Meanwhile, the welding part includes a support plate, and a welding head, a scraper and a feeding pipe are fixed on the bottom outer wall of the support plate. A feeder is connected to one side of the feeding pipe, and a welding material storage container is connected to the feeding side of the feeder.

[0016] As a preferred embodiment of the present invention, the support guide includes a roller frame supported by support legs and a plurality of support rollers rotatably connected to the inner side of the roller frame via roller shafts and used for supporting H-beams.

[0017] The beneficial effects of this invention are as follows: 1. The present invention, by setting a support guide as a support and then cooperating with the dynamic limiting part, enables the welding of H-beams to be carried out dynamically in an assembly line manner, thereby enabling dynamic connection with the preceding web and flange forming processes, and improving production efficiency.

[0018] 2. In this invention, by setting up a transmission assembly, the transmission action of bevel gear set one, bevel gear set two, and bevel gear set three is used to make the side limiting wheel and the bottom limiting wheel have a rigid transmission engagement, thereby ensuring that the conveying linear speed of the side limiting wheel and the bottom limiting wheel is completely consistent, ensuring that the conveying speed of the web and flange of the H-beam is completely consistent, thereby ensuring the accuracy of welding formation.

[0019] 3. In this invention, based on the limitation of the web and flange of the H-beam by setting side limit wheels and bottom limit wheels, an adjustment component is set up. The adjustment component can drive the adjustment frame one and adjustment frame two to make the side limit wheels adjust laterally and the bottom limit wheels adjust longitudinally. Thus, the position of the movable limit can be adaptively adjusted for H-beams of different sizes. At the same time, combined with the three-bar structure composed of connecting rod one, adjustment block and connecting rod two, which has two degrees of freedom, bidirectional adjustment can be achieved by using a telescopic rod as a single drive.

[0020] 4. The present invention uses roller support as a base and sets the support guide part as a unit linear array, so that the number of support guide parts can be selected according to the length of the H-beam being processed, thereby allowing the space occupation of the entire welding device to be adjusted accordingly.

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: A welding device for processing metal steel structures, such as Figures 1-6 As shown, it includes a gantry frame 3 and multiple sets of linearly arranged support guide parts 1 for supporting the components. The inner side of the gantry frame 3 is provided with multiple sets of dynamic limiting parts 4 for dynamically limiting the web and flange of the H-beam. Each set of dynamic limiting parts 4 is arranged in two symmetrical sets, and the inner side of one of the gantry frames 3 is provided with two sets of symmetrical welding parts 2 for welding the web and flange welds.

[0026] The dynamic limiting part 4 includes a support frame 9 fixed to the inner side of the gantry frame 3, a side limiting wheel 5 rotatably disposed on the side wall of the support frame 9, and a bottom limiting wheel 10 rotatably disposed at the bottom of the support frame 9. At the same time, the support frame 9 is also provided with a driving component 7 for synchronously driving the side limiting wheel 5 and the bottom limiting wheel 10.

[0027] When using this device, one flange of the H-beam can be laid flat on the support guide part 1, and then the web and flange are placed vertically. The side limiting wheel 5 and the bottom limiting wheel 10 are pressed to limit the movement. Then the driving component 7 drives the side limiting wheel 5 and the bottom limiting wheel 10 to rotate synchronously. The friction force can drive the web and flange of the H-beam to move linearly. When it moves to the position of the welding part 2, the two sets of symmetrical welding parts 2 weld the weld seam of the web and flange. After the welding is completed, the semi-finished product can be flipped over and welded again. Alternatively, two welding parts 2, gantry frame 3, and dynamic limiting part 4 can be set up, and the other flange can be welded after flipping. This achieves the welding and forming of the H-beam.

[0028] This device, by setting up a support guide part 1 as a support and then cooperating with the dynamic limiting part 4 for dynamic limiting, enables the welding of H-beams to be carried out dynamically in an assembly line manner, thereby dynamically connecting with the preceding web and flange forming processes and improving production efficiency.

[0029] To solve the driver problem; such as Figure 3 As shown, the side limiting wheel 5 and the driving component 7 are driven by a transmission assembly 6. The transmission assembly 6 includes an adjustment frame 13 located on the side of the support frame 9 and an adjustment frame 2 19 located at the bottom of the support frame 9. The side limiting wheel 5 and the bottom limiting wheel 10 are rotatably connected to the adjustment frame 13 and the adjustment frame 2 19 respectively by a wheel axle 11. The inner wall of the support frame 9 is also rotatably connected to a transition shaft 14 and a transition shaft 2 17. The wheel axle 11 connecting the side limiting wheel 5 and the transition shaft 14 are driven by a bevel gear set 12. The transition shaft 14 and the transition shaft 2 17 are driven by a bevel gear set 2 15. The transition shaft 2 17 and the wheel axle 11 connecting the bottom limiting wheel 10 are driven by a bevel gear set 3 18. The driving component 7 is a motor 16. The output shaft of the motor 16 is connected to the end of the transition shaft 14 by a coupling.

[0030] When the motor 16 starts, it drives the transition shaft 14 to rotate, which in turn drives the wheel axle 11 to rotate through the bevel gear set 12, and finally drives the side limit wheel 5 to rotate. When the transition shaft 14 rotates, it drives the transition shaft 17 to rotate through the bevel gear set 15, and then drives the bottom limit wheel 10 to rotate through the bevel gear set 18 and the wheel axle 11, thus realizing the synchronous rotation of the side limit wheel 5 and the bottom limit wheel 10.

[0031] This device, by setting up a transmission component 6, utilizes the transmission action of bevel gear set 12, bevel gear set 2 15, and bevel gear set 3 18 to make the side limiting wheel 5 and the bottom limiting wheel 10 have a rigid transmission engagement, thereby ensuring that the conveying linear speed of the side limiting wheel 5 and the bottom limiting wheel 10 is completely consistent, ensuring that the conveying speed of the web and flange of the H-beam is completely consistent, thus ensuring the accuracy of welding formation.

[0032] To address applicability issues, the dynamic limiting part 4 further includes an adjustment assembly 8 for adjusting the lateral position of the side limiting wheel 5 and the longitudinal position of the bottom limiting wheel 10. Simultaneously, the first bevel gear set 12 is rotatably connected to the inner wall of the first adjusting frame 13, and one of the bevel gears of the first bevel gear set 12 is axially slidably connected to the outer wall of the first transition shaft 14. The third bevel gear set 18 is rotatably connected to the inner wall of the second adjusting frame 19, and one of the bevel gears of the third bevel gear set 18 is axially slidably connected to the outer wall of the second transition shaft 17.

[0033] One of the bevel gears in bevel gear set 12 is axially slidably connected to the outer wall of transition shaft 14, and one of the bevel gears in bevel gear set 18 is axially slidably connected to the outer wall of transition shaft 27. Both connections are achieved through clearance fit between a key and a keyway.

[0034] One side of the adjustment frame 13 is rotatably connected to a connecting rod 20, and the top of the adjustment frame 19 is rotatably connected to a connecting rod 23. The other ends of the connecting rod 20 and the connecting rod 23 are rotatably connected to the same adjustment block 21. The side wall of the support frame 9 is fixed with a telescopic rod 22 by bolts, and the telescopic end of the telescopic rod 22 is rotatably connected to the side wall of the adjustment block 21.

[0035] When the telescopic rod 22 extends, it can drive the adjusting block 21 to move. This causes the adjusting frame 13 to move laterally via the first connecting rod 20, and then the side limiting wheel 5 to move laterally. On the other hand, it causes the adjusting frame 19 to move longitudinally via the second connecting rod 23, and then the bottom limiting wheel 10 to move longitudinally. During the movement, the three-bar linkage structure consisting of the first connecting rod 20, the adjusting block 21, and the second connecting rod 23 has two degrees of freedom. This means that when the side limiting wheel 5 or the bottom limiting wheel 10 moves to fit against the web or flange, the telescopic rod 22 continues to extend, causing the bottom limiting wheel 10 or the side limiting wheel 5 to continue moving until it fits against the flange or web, thus completing the double-sided limiting.

[0036] This device, based on the limitation of the web and flange of the H-beam by setting the side limiting wheel 5 and the bottom limiting wheel 10, can use the adjustment component 8 to drive the adjustment frame 13 and the adjustment frame 2 19 to make the side limiting wheel 5 adjust laterally and the bottom limiting wheel 10 adjust longitudinally. Thus, the position of the movable limit can be adaptively adjusted for H-beams of different sizes. At the same time, combined with the three-bar structure composed of the connecting rod 1 20, the adjustment block 21 and the connecting rod 23, which has two degrees of freedom, bidirectional adjustment can be achieved by using the telescopic rod 22 as a single drive.

[0037] To solve welding problems; such as Figure 5As shown, the welding part 2 includes a support plate 24. The bottom outer wall of the support plate 24 is fixed with a welding head 26, a scraper 27 and a feed pipe 28. A feeder 25 is connected to one side of the feed pipe 28, and a solder storage container is connected to the feed side of the feeder 25.

[0038] When the H-beam, which is in a limited position, moves to the welding section 2, the feeder 25 first delivers the solder from the solder storage container and sprays it onto the weld through the feed pipe 28. Then, as the H-beam moves, the scraper 27 smooths the solder, and then the welding head 26 performs arc welding.

[0039] In this embodiment, one flange of the H-beam can be laid flat on the support guide 1, and then the web and flange are placed perpendicularly. The telescopic rod 22 is then extended. When the telescopic rod 22 extends, it moves the adjusting block 21, thereby causing the adjusting frame 13 to move laterally via the first connecting rod 20, which in turn moves the side limiting wheel 5 laterally. Simultaneously, the adjusting frame 19 moves longitudinally via the second connecting rod 23, which in turn moves the bottom limiting wheel 10 longitudinally. During this movement, the three-bar linkage consisting of the first connecting rod 20, the adjusting block 21, and the second connecting rod 23 has two degrees of freedom. This allows the telescopic rod 22 to continue extending and moving the bottom limiting wheel 10 or the side limiting wheel 5 until it is in contact with the flange or web, completing the double-sided limiting. Then, the motor 16 is started. When the motor 16 starts, it can drive... The transition shaft 14 rotates, which in turn drives the wheel axle 11 to rotate via the bevel gear set 12, ultimately driving the side limiting wheel 5 to rotate. When the transition shaft 14 rotates, it drives the transition shaft 17 to rotate via the bevel gear set 15, and then drives the bottom limiting wheel 10 to rotate via the bevel gear set 18 and the wheel axle 11, achieving synchronous rotation of the side limiting wheel 5 and the bottom limiting wheel 10. This allows the web and flange of the H-beam to move linearly through friction. When the H-beam, which is dynamically limited, moves to the welding section 2, the feeder 25 first conveys the welding material from the welding material storage container and sprays it onto the weld through the feed pipe 28. Then, as the H-beam moves, the scraper 27 smooths the welding material, and then the welding head 26 performs arc welding. After welding, the semi-finished product can be flipped over and welded again. Alternatively, two welding sections 2, a gantry 3, and a dynamic limiting section 4 can be set up, and the other flange can be welded after flipping, thus achieving the welding and forming of the H-beam.

[0040] Example 2: A welding device for processing metal steel structures, such as Figure 6 As shown, in order to solve the support problem, this embodiment makes the following improvements based on embodiment 1: the support guide part 1 includes a roller frame 31 supported by a support leg 29 and a plurality of support rollers 32 rotatably connected to the inner side of the roller frame 31 by roller shafts 30 and used to support the H-beam.

[0041] In this embodiment, by using roller support as the basis and then setting the support guide 1 as a unit linear array, the number of support guides 1 can be selected according to the length of the H-beam being processed, thereby allowing for targeted adjustment of the space occupied by the entire welding device.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
