[0001] This application relates to the technical field of metal processing, and in particular to a welding apparatus based on H-beam processing. Background Technology

[0002] H-beams are an economical and efficient profile with an H-shaped cross-section. They offer advantages such as high bending resistance, simple construction, cost savings, and lightweight construction, and are widely used in construction, bridges, and machinery manufacturing. During the welding process of H-beams, the web and flanges need to be welded on both sides.

[0003] Existing H-beams are mainly welded using gantry-type submerged arc welding machines, referring to... Figure 1 The welding machine mainly consists of two parts: a support system and a welding system. Specifically, the support system includes two symmetrically arranged steel inclined support frames, which are in an inclined "L" shape. The welding system includes a portal truss and submerged arc welding equipment mounted on the truss. The truss can slide along the length of the H-beams via a track, and the welding equipment on the truss is arranged in two sets, allowing simultaneous processing and welding of the H-beams on both sets of support frames.

[0004] Regarding the aforementioned technologies, there are four welding points for H-beams. After each welding is completed, a crane is required in conjunction with manual operation to move or haul them. The entire process is time-consuming, labor-intensive, and poses safety hazards. Summary of the Invention

[0005] To facilitate the flipping of H-beam steel plates and improve processing efficiency, this application provides a welding device based on H-beam steel processing.

[0006] This application provides a welding device based on H-beam steel processing, which adopts the following technical solution: A welding device based on H-beam processing includes a support system, a welding system, and a reversing system; The support system includes a support base and inclined support frames. Multiple inclined support frames are spaced apart along the length of the support base, and the inclined support frames are symmetrically arranged on the support base. The reversing system includes a feeding platform, a first rotating disc, a second rotating disc, a vertical moving component, a horizontal moving component, a first rotating component, a second rotating component, and a limiting component. The feeding platform is disposed between two adjacent sets of inclined support frames, and is parallel to the width direction of the support base. The vertical moving component controls the vertical movement of the feeding platform. The horizontal moving component is disposed on the feeding platform and can drive the H-beam to reciprocate towards the center. The first rotating disc is disposed at both ends of the support base, and the first rotating component can drive the first rotating disc to rotate. The second rotating disc is rotatably disposed within the first rotating disc and is disposed on the left and right sides of the first rotating disc. The second rotating component can drive the second rotating disc to rotate. The first transfer tray has a first storage groove on each of its two side walls; the second transfer tray has a second storage groove on the side facing the H-beam, the second storage groove passes through both side walls of the second transfer tray, and the second storage groove is connected to the first storage groove; the horizontal moving component can drive the H-beam through the first storage groove and into the second storage groove, and the limiting component can prevent the H-beam from coming out of the second storage groove.

[0007] By adopting the above technical solution, the support base of the support system and multiple symmetrically arranged inclined support frames can provide stable support for the H-beams; the unloading platform of the reversing system, together with the up-and-down moving components, can move up and down, and the horizontal moving components can drive the H-beams to move back and forth towards the center. The first and second rotating discs are driven to rotate by the first and second rotating components, respectively. The first and second placement slots are connected to facilitate the movement of the H-beams, and the limiting components can prevent the H-beams from falling out. The whole system realizes automatic reversing of the H-beams during the welding process, avoiding the need for crane hoisting and manual operation after each welding, saving manpower and time, and eliminating safety hazards.

[0008] Optionally, the up-and-down moving component includes a positioning post, a first screw, and a first power source. The positioning post is respectively arranged on both sides of the support base along the width direction of the support base. The positioning post is provided with a first sliding groove for the unloading platform to move up and down. The first screw is rotatably mounted on the positioning post in the vertical direction, and the first screw is threaded through the unloading platform. The first power source is used to drive the first screw to rotate.

[0009] By adopting the above technical solution, the first screw is driven to rotate by the first power source, which enables the unloading platform to move smoothly up and down along the first sliding groove on the positioning column.

[0010] Optionally, the horizontal moving component includes a conveyor belt and a second power source. The conveyor belt is respectively arranged at both ends of the unloading platform along the length direction of the unloading platform, and the power source is also provided with two sets for controlling the rotation of the two conveyor belts respectively.

[0011] By adopting the above technical solution, the conveyor belts set at both ends of the unloading platform rotate under the drive of the second power source, which can drive the two H-beams to move back and forth towards the center at the same time, realizing the horizontal movement of the H-beams in the welding device. This provides a basis for the H-beams to enter the first and second storage slots to complete the reversing operation, avoids manual operation of the movement of the H-beams, and improves the efficiency and safety of the H-beam welding process.

[0012] Optionally, the first rotating assembly includes a positioning platform, a first rotating shaft, and a third power source. One end of the first rotating shaft is rotatably mounted on the positioning platform, and the other end is connected to the first rotating material tray. The third power source can drive the first rotating shaft to rotate.

[0013] By adopting the above technical solution, the first rotating shaft is driven to rotate by the third power source, which in turn drives the first rotating plate to rotate. This enables the H-beams to rotate and change direction at the first rotating plate. At the same time, the two H-beams can be swapped left and right, avoiding the need for crane hoisting and manual operation to flip or move them after each welding. This saves time and manpower and eliminates safety hazards.

[0014] Optionally, the second rotating component includes a drive wheel and a fourth power source. The drive wheel is rotatably disposed within the first rotating disk. The outer side wall of the second rotating disk is circumferentially provided with teeth. The drive wheel meshes with the teeth. The fourth power source can drive the drive wheel to rotate.

[0015] By adopting the above technical solution, and utilizing the meshing structure between the drive wheel and the outer side teeth of the second rotating disc, in conjunction with the fourth power source driving the drive wheel to rotate, the rotation of the second rotating disc can be precisely controlled, thereby controlling the rotation of the H-beam within the second rotating disc.

[0016] Optionally, the second transfer tray is also provided with a limiting component to restrict the H-beam from coming out. The limiting component includes a limiting block, a connecting rod and a fifth power source. Two limiting blocks are spaced apart. The connecting rod is connected between the two limiting blocks. The fifth power source can control the limiting blocks to slide towards the second storage groove and insert their ends into the second storage groove.

[0017] By adopting the above technical solution, when the H-beam is located in the second storage slot, the fifth power source can drive the limiting block to slide and insert into the second storage slot, thus preventing the H-beam from coming out of the second storage slot during rotation.

[0018] Optionally, multiple unloading platforms are spaced apart along the length of the support base, and the first transfer tray is respectively disposed at both ends of the support base.

[0019] Optionally, both ends of the support base are provided with adjustment seats, and the adjustment seats are provided with drive components for controlling the positioning platform to move toward or away from the support base.

[0020] By adopting the above technical solution, adjustment seats and a third driving component are set at both ends of the support base, which can control the positioning table to move towards or away from the support base, thereby adjusting the position of the first rotating material plate, so that the device can adapt to the welding requirements of H-beams of different lengths and specifications, and enhance the applicability and flexibility of the device.

[0021] Optionally, the drive assembly includes a second screw and a sixth power source. The adjustment seat has a second sliding groove for the lower end of the positioning table to be inserted and slid. The second screw is rotatably mounted on the adjustment seat and threaded through the positioning table. The sixth power source can drive the second screw to rotate.

[0022] By adopting the above technical solution, the second screw is driven to rotate by the sixth power source, which allows the positioning table to slide in the second sliding groove of the adjusting seat. This enables the positioning table to move towards or away from the support base, facilitating the adjustment of the relative position between the first transfer plate and the H-beam, thus better adapting to the welding requirements of different specifications of H-beams and improving the versatility and flexibility of the welding device.

[0023] In summary, this application includes at least one of the following beneficial effects: 1. By utilizing the reversing system, the need for overhead cranes to lift and manually operate the H-beams after each welding is eliminated, saving manpower and time; 2. By rotating and cooperating the first and second rotating discs, all four welding points of the H-beam can be welded. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a welding apparatus based on the processing of H-beams. (Refer to...) Figure 1 The welding device includes a support system 1, a welding system 2, and a reversing system 3. The support system 1 is used to support the H-beam and other parts of the entire device. The welding system 2 performs welding processing on the H-beam. The reversing system 3 can realize the automatic reversing of the H-beam, avoiding the trouble and safety hazards of manual operation.

[0027] Reference Figure 1 and Figure 2 In this embodiment, both the support system 1 and the welding system 2 are existing technologies. For ease of understanding, the relevant structures are briefly described below. The support system 1 includes a support base 11 and an inclined support frame 12. The support base 11 can be welded from steel, forming a rectangular frame structure, which serves as a support. The inclined support frame 12 is fixed to the support base 11 by welding. Multiple inclined support frames are spaced apart along the length of the support base 11 and symmetrically arranged on the support base 11 along its width. The inclined support frame 12 can be welded from steel pipes, forming an inclined "L" shape. Its function is to support H-beams and keep them in a stable position during welding. It is important to note that the inclined support frame 12 consists of two inclined rods. The inclined rod furthest from the other inclined support frame 12 has an inclination angle of 0-45°, preferably 30°; the other inclined rod has an inclination angle of 45-90°, preferably 60°, and the included angle between the two inclined rods is 90°.

[0028] The welding system 2 mainly includes a portal truss 21 and submerged arc welding equipment 22 installed on the truss. The portal truss 21 spans across the support base 11 along the width direction. Two sets of submerged arc welding equipment 22 are spaced apart on the portal truss 21. The portal truss 21 moves along the length direction of the support base 11 via a track, so that the two sets of welding equipment 22 can simultaneously weld two H-beams placed on the inclined support frame 12.

[0029] Reference Figure 2 and Figure 3 In this embodiment, the reversing system 3 includes a feeding platform 31, a first rotating disc 32, a second rotating disc 33, a vertical moving component 34, a horizontal moving component 35, a first rotating component 36, a second rotating component 37, and a limiting component 38. The feeding platform 31 is disposed between two adjacent sets of inclined support frames 12, and its length direction is parallel to the width direction of the support base 11. Multiple feeding platforms 31 are spaced apart along the length direction of the support base 11.

[0030] The vertical movement assembly 34 controls the vertical movement of the unloading platform 31. It includes a positioning post 341, a first screw 342, and a first power source 343. The positioning post 341 is positioned on both sides of the support base 11 along its width direction, and has a first sliding groove for the unloading platform 31 to move vertically. The first screw 342 is rotatably mounted on the positioning post 341 in a vertical direction and is threaded through the unloading platform 31. The first power source 343 can be a motor, which drives the first screw 342 to rotate. Because the first screw 342 is threadedly connected to the unloading platform 31, the unloading platform 31 moves vertically along the first sliding groove on the positioning post 341. Furthermore, a guide rod can be provided on the positioning post 341, which is vertically positioned and slides through the unloading platform 31.

[0031] In the initial state, the position of the unloading platform 31 is lower than the position of the inclined support frame 12, and the welding equipment 22 can weld the H-beam. After one side of the H-beam is welded, the first power source 343 can be started to move the unloading platform 31 upward, so that the H-beam can be removed from the inclined support frame 12 and changed from an inclined position to a horizontal position on the unloading platform 31.

[0032] A horizontal moving assembly 35 is mounted on the unloading platform 31 and can drive the H-beam to reciprocate towards the center. The horizontal moving assembly 35 includes a conveyor belt 351 and a second power source 352. The conveyor belt 351 is positioned at both ends of the unloading platform 31 along its length. Two sets of the second power sources 352 are also provided to control the rotation of the two conveyor belts respectively. The second power source 352 can be a motor, which drives the conveyor belt 351 to rotate, thereby achieving the horizontal movement of the H-beam. The conveyor belt 351 can be made of rubber to increase friction with the H-beam; it can also be made of metal to improve its durability.

[0033] In an optional embodiment, partition plates may be spaced apart on the surface of the conveyor belt 351, with the distance between two adjacent partition plates being greater than the width of the H-beam. This arrangement is intended to prevent the H-beam from slipping off the conveyor belt 351 when it is placed on the conveyor belt 351.

[0034] Reference Figure 2 and Figure 4 Along the length of the support base 11, a first rotating disk 32 is respectively disposed at both ends of the support base 11, and a first rotating assembly 36 can drive the first rotating disk 32 to rotate. Specifically, the first rotating assembly 36 includes a positioning platform 361, a first rotating shaft 362, and a second power source 352. The positioning platform 361 is disposed vertically and serves to support and raise the first rotating disk 32. One end of the first rotating shaft 362 is rotatably disposed on the positioning platform 361 by means of bearings or the like, and the other end is connected to the first rotating disk 32. The second power source 352 can drive the first rotating shaft 362 to rotate. The second power source 352 can be a motor, which drives the first rotating shaft 362 to rotate, thereby causing the first rotating disk 32 to rotate; the second power source 352 can also be composed of a motor, a sprocket, and a chain, which drives the first rotating disk to rotate through chain transmission.

[0035] Reference Figure 4 and Figure 5 The second rotating disk 33 is rotatably disposed within the first rotating disk 32 and is respectively disposed on the left and right sides of the first rotating disk 32. The second rotating assembly 37 can drive the second rotating disk 33 to rotate. The second rotating assembly 37 includes a drive wheel 371 and a third power source 363. The drive wheel 371 is rotatably disposed within the first rotating disk 32. The outer wall of the second rotating disk 33 is circumferentially provided with teeth 332. The drive wheel 371 meshes with the teeth 332. The third power source 363 can drive the drive wheel 371 to rotate. The third power source 363 can be a motor. The motor drives the drive wheel 371 to rotate. Because the drive wheel 371 meshes with the teeth 332 on the outer wall of the second rotating disk 33, the second rotating disk 33 rotates.

[0036] Furthermore, a first storage groove 321 is provided on both side walls of the first transfer plate 32; a second storage groove 331 is provided on the side of the second transfer plate facing the H-beam. The second storage groove 331 passes through both side walls of the second transfer plate 33 and is connected to the first storage groove 321. At the same time, the heights of the first storage groove 321 and the second storage groove 331 are adapted to the height of the H-beam. When both the first transfer plate 32 and the second loading plate are in a horizontal state, the conveyor belt 351 can drive the H-beam through the first storage groove 321 and into the second storage groove 331.

[0037] A limiting member 38 is disposed within the second transfer tray 33 to prevent the H-beam from escaping the second storage slot 331. The limiting member 38 includes a limiting block 381, a connecting rod 382, ​​and a fourth power source 372. Two limiting blocks 381 are spaced apart, and the connecting rod 382 connects the two limiting blocks 381. The fourth power source 372 controls the limiting blocks 381 to slide towards the second storage slot 331 and insert their ends into the second storage slot 331. The fourth power source 372 can be a cylinder, with its extension shaft connected to the connecting rod 382, ​​allowing the cylinder to push the limiting blocks 381 to move. Initially, the limiting blocks 381 and the connecting rod 382 are both housed within the second transfer tray 33. When the H-beam enters the second storage slot 331, the cylinder drives the limiting blocks 381 to move and insert into the second storage slot 331, securing the H-beam between the two limiting blocks 381 and preventing it from escaping.

[0038] Preferably, a guide slope can be provided on the side wall of the two limiting blocks 381 that are close to each other, so as to facilitate the insertion of the H-beam into the two limiting blocks 381. At the same time, the limiting members 38 can be symmetrically arranged in two sets on the upper and lower sides of the second storage groove 331 according to the actual space.

[0039] Reference Figure 2 and Figure 4 In an optional embodiment, the distance between the two first rotating discs 32 can be adjusted to accommodate H-beams of different lengths. Specifically, both ends of the support base 11 are provided with adjusting seats 4, and the adjusting seats 4 are equipped with a drive assembly 5 for controlling the positioning platform 361 to move towards or away from the support base 11. The drive assembly 5 includes a second screw 51 and a sixth power source 52. The adjusting seat 4 has a second sliding groove for the lower end of the positioning platform 361 to be inserted and slid. The second screw 51 is rotatably mounted on the adjusting seat 4 and threaded through the positioning platform 361. The sixth power source 52 can drive the second screw 51 to rotate. The sixth power source 52 is usually a motor, which drives the second screw 51 to rotate. Since the second screw 51 is threadedly connected to the positioning platform 361, the horizontal movement of the positioning platform 361 is achieved. Similarly, a guide rod can also be provided in the second sliding groove on the adjusting seat 4. The guide rod slides through the lower end of the positioning platform 361, thereby improving its movement stability.

[0040] The implementation principle of a welding device based on H-beam processing in this application embodiment is as follows: When welding H-beams, two H-beams are first placed on the left and right sets of inclined support frames 12 respectively, and the welding equipment 22 is driven by the portal truss 21 to perform synchronous welding; the following refers to Figure 6 The diagram shows the welding position of the H-beams located on the left inclined support frame 12. After the first connection 101 on the first surface of the H-beams is welded, the first power source 343 is started to drive all the unloading platforms 31 to move upward, so that the two H-beams fall on the unloading platforms 31. After reaching the specified height, the second power source 352 is started to drive the two H-beams to move towards the middle first rotating plate 32 at the same time, and drive the two H-beams to move into the first placement slots 321 on both sides of the first rotating plate 32, and into the second placement slots 331. Then the fifth power source 383 is started to drive the limiting block 381 to slide to both sides of the H-beams. Then the fourth power source 372 is started to drive the second rotating plate 33 to rotate, drive the H-beams to rotate 180°, unlock the limiting piece 38, and move in the opposite direction to send the H-beams back to the inclined support frame 12. At this time, the second connection 102 on the second surface of the H-beams can be welded. After welding is completed, the H-beam is fed into the second storage slot 331 again through the unloading platform 31 and limited again by the limiting member 38. At this time, the third power source 363 is started to drive the first rotating plate 32 to rotate, the two H-beams interchange positions and rotate 180°. Then, the H-beam is fed onto the inclined support frame 12 again through the unloading platform 31. At this time, the third connection 103 on the first surface of the H-beam can be welded. Finally, the second rotating plate 33 rotates circumferentially once to weld the fourth connection 104 on the second surface. The welding device of this application can be used to process H-beams, and the welding of the four joints of the H-beams can be completed in sequence through the reversing system 3 without the need for manual assistance.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
