[0001] The present invention relates to the technical field of flange welding, and particularly relates to a welding device and method for flange production. Background Art

[0002] In the production process of traditional integral flanges, a large amount of scrap is generated during the cutting of raw materials, resulting in material waste and significantly increasing production costs. In view of this, a production process of splicing and welding four arc-shaped plates has emerged. This process can greatly improve the utilization rate of raw materials and effectively reduce production costs. However, during the current splicing and welding process of four arc-shaped plates, the alignment of the arc-shaped plates mainly relies on manual operation. This not only requires workers to have rich operation experience, but also has a high labor intensity and low production efficiency. The accuracy of manual alignment is difficult to guarantee, seriously affecting the consistency of product quality. Moreover, in the pre-treatment stage before welding, the welding surface is mostly polished manually.

[0014] Beneficial effects of the present invention: (1) The present invention describes a welding device and method for flange production.

[0015] (2) The present invention describes a welding device and method for flange production. The arc plate moves under the drive of the driving assembly and is in compression contact with the grinding assembly, driving the grinding assembly to work and grind its own welding end surface. At the same time, the extrusion force of the arc plate is transmitted through the grinding plate, prompting the piston rod in the vibration assembly to move, driving the piston plate to slide in the piston cylinder, causing the piston cylinder to reciprocate up and down, thereby enhancing the grinding effect and making the welding surface smoother and flatter, meeting the welding requirements.

[0016] (3) In the welding device and method for flange production described in the present invention, when the arc plate moves to a specific position and is out of extrusion contact with the grinding plate, the first spring installed on the outside of the piston rod drives the piston plate to reset and move. At this time, the one-way air inlet valve of the air blowing cleaning assembly is closed, and the one-way air outlet valve is opened. The gas in the piston cylinder is ejected to blow away the debris and impurities generated by the grinding of the arc plate, thereby ensuring the cleanliness of the welding surface and improving the welding quality.

Detailed implementation manners

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0020] In order to facilitate the splicing and welding of flanges and improve the production efficiency of flange plates, as an embodiment of the present invention, as Figure 1-3 shown, a welding device and method for flange production according to the present invention includes a welding device, and a support platform 1 distributed around the welding device. The support platform 1 is horizontally arranged. A driving component for driving the arc-shaped plate to move is provided on the support platform 1. Support components are provided between adjacent support platforms 1. Grinding components are provided above the support components. A vibration component for driving the grinding component to vibrate is connected between the grinding component and the support component. A blowing and cleaning component is provided on one side of the grinding component.

[0021] During use, the arc-shaped plate to be welded is horizontally placed on the support platform 1. Subsequently, the driving component is started, and the driving component drives the arc-shaped plate to move on the support platform 1. During the movement, the end of the arc-shaped plate is in close extrusion contact with the grinding component. At this stage, the grinding component grinds the welding end face of the arc-shaped plate by virtue of the relative movement with the arc-shaped plate. At the same time, when the arc-shaped plate presses the grinding component, the vibration component works and drives the grinding component to perform reciprocating up and down movements, so as to enhance the grinding effect on the welding surface of the arc-shaped plate and ensure the welding quality of subsequent welding; During the period when the driving component drives the arc-shaped plate to move, the extrusion contact between the end of the arc-shaped plate and the grinding component also plays a role in position adjustment. The grinding component squeezes the arc-shaped plate, causing both ends of the arc-shaped plate to move along a specific track of the grinding component, thereby realizing the positioning and grinding of the arc-shaped plate. When the arc-shaped plate is driven to a specific position, both ends of the arc-shaped plate are separated from the grinding component. At this time, the air blowing and cleaning component works to comprehensively clean the welded surface of the arc-shaped plate that has been ground, effectively removing the debris and impurities generated during the grinding process, ensuring the cleanliness of the welded surface, and further improving the quality and effect of subsequent welding; As the driving component continuously drives the arc-shaped plate to move, when the end of the arc-shaped plate is accurately in contact with the end of the adjacent arc-shaped plate, a series of operations such as alignment, grinding, and grinding surface cleaning have been completed. At this time, the welding device starts to work to weld the adjacent arc-shaped plates, improving the efficiency of flange splicing welding and effectively enhancing the overall production efficiency of the flange plate.

[0022] For the convenience of driving the arc-shaped plate to move, by way of example, as Figure 1 、 Figure 3 、 Figure 6 shown, the present invention further includes that the driving component includes an electric track 2 horizontally arranged on the upper surface of the support platform 1. A sliding seat 3 is slidably connected to the electric track 2. A plurality of groups of vertically arranged first adjusting rollers 4 are provided on one side of the sliding seat 3. The first adjusting rollers 4 are in extrusion contact with the outer side of the arc-shaped plate. The upper and lower ends of the first adjusting rollers 4 are rotatably connected to a support plate 5. One end of the support plate 5 away from the first adjusting rollers 4 is fixedly connected to one side of the sliding seat 3; an extrusion adjusting component is provided on the support platform 1 and is in extrusion contact with the inner side of the arc-shaped plate.

[0023] During use, place the arc-shaped plate to be welded on the electric track 2 of the support platform 1, turn on the driving device of the electric track 2, and make the sliding seat 3 start to slide on the electric track 2. As the sliding seat 3 slides, the first adjusting roller 4 on one side of the sliding seat 3 comes into extrusion contact with the outer side of the arc-shaped plate. Under the action of the first adjusting roller 4, the arc-shaped plate starts to move. Since the lower end of the first adjusting roller 4 is fixedly connected to the sliding seat 3 through the support plate 5, it can stably push the arc-shaped plate. During the movement of the arc-shaped plate, the extrusion adjusting component on the support platform 1 comes into extrusion contact with the inner side of the arc-shaped plate. When the arc-shaped plate moves to a certain position and comes into extrusion contact with the grinding component, the grinding component fine-tunes the position of the arc-shaped plate by extruding the arc-shaped plate, ensuring the stability and accuracy of the arc-shaped plate during movement, so that the arc-shaped plate can move to the appropriate welding position along the predetermined trajectory.

[0024] For the convenience of adjusting the position of the arc-shaped plate, exemplarily, as Figure 6 shown, the present invention further includes that the extrusion adjusting component includes a slot 6 symmetrically arranged on the upper surface of the support platform 1. A pressing block 7 is slidably connected in the slot 6. A vertically arranged second adjusting roller 8 is provided on the side of the pressing block 7 close to the first adjusting roller 4. Both ends of the second adjusting roller 8 are rotatably connected with a horizontally arranged connecting piece 9. The end of the connecting piece 9 away from the second adjusting roller 8 is fixedly connected to one side of the pressing block 7. A pressing spring 10 is fixedly connected between the side of the pressing block 7 away from the second adjusting roller 8 and the inner wall of the slot 6.

[0025] During use, start the electric track 2 and the sliding seat 3 to drive the first adjusting roller 4 to move and extrude the outer side of the arc-shaped plate, so that the arc-shaped plate starts to move. When the arc-shaped plate moves, the inner side of the arc-shaped plate will extrude the second adjusting roller 8. After the second adjusting roller 8 is stressed, it drives the pressing block 7 to slide in the slot 6 through the connecting piece 9. The pressing block 7 extrudes the pressing spring 10. The reaction force generated by the pressing spring 10 is fed back to the arc-shaped plate through the pressing block 7 and the second adjusting roller 8. Under the combined action of the first adjusting roller 4 and the second adjusting roller 8, the arc-shaped plate starts to be preliminarily positioned and moves along the predetermined direction, ensuring that the end gradually approaches the grinding component; During the flange production process, when the grinding assembly is in squeeze contact with the end of the arc plate, grinding and guiding are performed simultaneously; as the arc plate moves, the grinding assembly guides the end of the arc plate to move along a specific trajectory, during which the first adjusting roller 4 and the second adjusting roller 8 work closely together to provide stable support from the inside and outside of the arc plate, and play an auxiliary guiding role, effectively avoiding shaking or deviation of the arc plate during movement, and ensuring the stability and accuracy of the movement of the arc plate; with the help of the coordinated action of the first adjusting roller 4, the second adjusting roller 8 and the grinding assembly, the end position of the arc plate is continuously adjusted in the process of gradually approaching the adjacent arc plate, and finally, the end of the arc plate is precisely aligned with the end of the adjacent arc plate, ensuring the position accuracy of the subsequent welding operation and improving the quality of flange splicing and overall production efficiency.

[0026] In order to grind the welding end surface of the arc plate, for example, Figure 1 , Figure 3 , Figure 4 , Figure 7 As shown, the present invention also includes that the grinding assembly includes two groups of mounting plates 11 vertically arranged above the supporting assembly, and a plurality of groups of horizontally arranged gas spring rods 12 are detachably connected between the two groups of mounting plates 11, and a grinding plate 13 is detachably connected to one side of the mounting plate 11 away from the gas spring rod 12; a vibration assembly is connected between the two groups of mounting plates 11.

[0027] When in use, when the arc plate to be welded moves to contact with the grinding assembly under the action of the driving assembly, the end of the arc plate squeezes the grinding plate 13. At this time, the gas spring rod 12 will expand and contract to a certain extent according to the squeezing force of the arc plate, which plays a role in buffering and adjusting the contact strength between the grinding plate 13 and the arc plate. At the same time, the vibration assembly starts to work, driving the two sets of mounting plates 11 and the grinding plate 13 to do up and down reciprocating motion. In this process, the grinding plate 13, supported by the gas spring rod 12 and driven by the vibration assembly, continuously grinds the welding end surface of the arc plate to meet the surface treatment requirements before welding; When the arc plate squeezes the grinding plate 13, the grinding assembly generates a reaction force on the arc plate. The first adjusting roller 4 and the second adjusting roller 8 provide support from the inside and outside of the arc plate respectively. During the movement of the arc plate, they cooperate with the squeezing of the grinding plate 13 to effectively reduce the shaking or deviation of the arc plate.

[0028] In order to facilitate the piston cylinder 14 to move up and down, for example, Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 8As shown, the present invention further includes that the vibration assembly includes a piston cylinder 14 with both ends closed. Both ends of the piston cylinder 14 are hermetically and slidably connected to a piston rod 15 connected to the mounting plate 11. At both ends inside the piston cylinder 14, piston plates 16 hermetically and slidably connected to the ends of the piston rod 15 are provided. A first spring 17 is sleeved and connected outside the piston rod 15 between the mounting plate 11 and the piston cylinder 14; A vertically arranged sleeve 18 communicates with the lower side of the middle part of the piston cylinder 14. A horizontally arranged driving plate 19 is hermetically and slidably connected inside the sleeve 18. A vertically arranged driving rod 20 is fixedly connected to the lower surface of the driving plate 19. The lower end of the driving rod 20 is connected to the support assembly. An air outlet pipe 21 communicates with the lower side surface of the lower part of the sleeve 18. A second spring 37 is fixedly connected between the lower end of the sleeve 18 and the support assembly.

[0029] During use, the extrusion force applied by the arc-shaped plate is transmitted to the mounting plate 11 through the grinding plate 13, prompting the mounting plate 11 to squeeze the piston rod 15. The piston rod 15 is connected to the piston plate 16, driving the piston plate 16 to perform a sealed sliding movement inside the piston cylinder 14. Since the piston plate 16 maintains a tight sealed connection with the inner wall of the piston cylinder 14, the sliding of the piston plate 16 will cause a change in the gas pressure inside the piston cylinder 14; when the piston plate 16 moves, the gas pressure inside the piston cylinder 14 increases, and the driving plate 19 moves upward under the action of the gas pressure, further pushing the sleeve 18 upward. The upward movement of the sleeve 18 drives the connected piston cylinder 14, piston plate 16, piston rod 15, mounting plate 11, and grinding plate 13 to move upward together; When the sleeve 18 moves upward to a specific position, the air outlet pipe 21 at the lower part of the sleeve 18 is exactly located above the driving plate 19. At this time, the air outlet pipe 21 communicates with the inside of the piston cylinder 14, forming a gas discharge channel. As the piston plate 16 continues to move, the gas inside the piston cylinder 14 is discharged through the air outlet pipe 21, and the gas pressure inside the cylinder rapidly decreases. Under the elastic reset action of the first spring 17 and the second spring 37, the sleeve 18 and the connected piston cylinder 14 quickly move downward for reset; When the sleeve 18 resets and moves downward to a certain position, the communication between the air outlet pipe 21 and the inside of the piston cylinder 14 is cut off, and the gas discharge stops. At this time, as the arc-shaped plate continues to move and squeeze, the piston plate 16 moves again inside the piston cylinder 14, and the generated gas re-enters the sleeve 18 through the piston cylinder 14, squeezing the driving plate 19 again, triggering a new round of upward movement of the sleeve 18 and the piston cylinder 14; through the periodic gas pressure change, the up-and-down reciprocating movement of the piston cylinder 14 is realized. The reciprocating movement enables the grinding plate 13 installed on the mounting plate 11 to continuously grind the welded end face of the arc-shaped plate, providing a reliable surface treatment basis for subsequent high-quality welding operations.

[0030] Exemplarily, such as Figure 1 、Figure 3 As shown, the present invention further includes that the support assembly includes a number of groups of support legs 22 vertically arranged on the lower surface of the support platform 1. A horizontally arranged arc-shaped fixing plate 23 is fixedly connected between adjacent support legs 22. The lower end of the driving rod 20 is fixedly connected with a connecting seat 24. The lower surface of the connecting seat 24 is detachably connected with a support seat 25. Both sides of the support seat 25 are fixedly connected with the inner side of the corresponding arc-shaped fixing plate 23.

[0031] During use, a number of groups of support legs 22 are vertically installed on the lower surface of the support platform 1 to provide a stable support foundation for the entire device; between adjacent support legs 22, an arc-shaped fixing plate 23 is horizontally and fixedly connected to form a stable frame structure, enhancing the overall stability of the support assembly; the lower end of the driving rod 20 is fixedly connected with the connecting seat 24 to ensure the firmness of the connection, enabling the power of the driving rod 20 to be effectively transmitted to the connecting seat 24, and at the same time ensuring the stability of the up and down movement of the sleeve 18.

[0032] Exemplarily, as Figure 1 、 Figure 4 、 Figure 7 As shown, the present invention further includes that the piston cylinder 14 is fixedly connected to the side of the gas spring rod 12 through a connecting plate 26. A number of groups of positioning holes 27 are provided on the connecting plate 26. A number of groups of positioning rods 28 corresponding to the positioning holes 27 are provided on the upper surface of the arc-shaped fixing plate 23. The positioning rods 28 pass through the positioning holes 27 and are slidably connected to the positioning holes 27.

[0033] During use, when the vibration assembly drives the piston cylinder 14 to move, the positioning rods 28 slide along the positioning holes 27 to limit the movement trajectory of the piston cylinder 14, preventing the grinding assembly from shifting, shaking, etc. during movement, and ensuring that the piston cylinder 14 stably drives the grinding plate 13 to grind the arc-shaped plate with the assistance of the gas spring rod 12.

[0034] To facilitate the cleaning of the grinding and welding surface of the arc-shaped plate, exemplarily, as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, the present invention further includes that the air blowing and cleaning assembly includes a one-way air outlet valve 29 and a one-way air inlet valve 30 connected to both ends of the piston cylinder 14. The one-way air outlet valves 29 are commonly connected to a horizontally arranged connecting pipe 31. One side of the connecting pipe 31 is detachably connected to a spray pipe 32. The end of the spray pipe 32 away from the connecting pipe 31 is connected to an inclined jet nozzle 33.

[0035] When in use, during the operation of the flange welding device, when the arc plate gradually approaches and squeezes the grinding plate 13 under the action of the driving assembly, the grinding plate 13 is subjected to the squeezing force, and the force is transmitted to the mounting plate 11 connected thereto, thereby driving the piston rod 15 to move, so that the piston plate 16 moves in the piston cylinder 14. At this time, the outside air is sucked into the piston cylinder 14 on the side of the piston plate 16 close to the piston rod 15 through the one-way air inlet valve 30; As the arc plate continues to move, when the arc plate reaches a specific position, it will break away from the extrusion contact with the grinding plate 13. At this time, the first spring 17 rebounds to drive the piston plate 16 to reset. During the reset process of the piston plate 16, the gas is transported to the connecting pipe 31 through the one-way air outlet valve 29; the gas enters the air injection pipe 32 along the connecting pipe 31, and finally sprays from the inclined air injection nozzle 33 onto the polished welding surface of the arc plate, blowing away the debris and impurities generated during the grinding process, so that the welding surface remains clean, the quality of the welding surface is improved, and the overall quality of the flange welding is guaranteed.

[0036] In order to facilitate the welding operation on the curved plate, for example, Figure 1 , Figure 2 As shown, the present invention also includes that the welding device includes a base 34 arranged between a plurality of groups of support platforms 1, a mechanical arm 35 is provided above the base 34, and a welding gun 36 is detachably connected to the mechanical arm 35.

[0037] When in use, after confirming that the arc plate has completed preliminary processes such as positioning, grinding and cleaning, and the position of the welding gun 36 has been adjusted appropriately, the welding device is started, and the robotic arm 35 drives the welding gun 36 to move according to the preset welding path and parameters to perform welding operations on adjacent arc plates, thereby completing the splicing and welding operations of the flange.

[0038] The present invention also provides a flange production welding method, which uses the above-mentioned flange production welding device and comprises the following steps: S1, placing multiple sets of arc-shaped plates on the support platform 1, and driving the arc-shaped plates to move closer together and assemble into flange plates through the driving components; S2, grinding the welding end surface of the arc plate by a grinding assembly while the arc plate is approaching; S3, after the arc plate welding end surface is polished, the arc plate welding end surface is cleaned by using an air blowing cleaning component; S4. After the arc plates are brought close to each other, the arc plates are welded to their end surfaces by a welding device.

[0039] When the present invention is used, the arc plate to be welded is horizontally placed on the electric track 2 of the support platform 1 to ensure that the arc plate is in a stable position in preparation for subsequent movement and processing; The driving device of the electric track 2 is turned on, and the slide 3 slides on the electric track 2. The first adjusting roller 4 on one side of the slide 3 is pressed and contacted with the outer side of the arc plate to push the arc plate to move. At the same time, the extrusion adjustment component on the support platform 1 starts to work, and the inner side of the arc plate squeezes the second adjusting roller 8. The second adjusting roller 8 drives the extrusion block 7 to slide in the slot 6 through the connecting piece 9. The extrusion spring 10 generates a reaction force to assist the arc plate in preliminary positioning and move along the predetermined direction, so that its end gradually approaches the grinding component; When the grinding assembly is in squeeze contact with the end of the arc plate, grinding and guiding are performed simultaneously; as the arc plate moves, the grinding plate 13 guides the end of the arc plate to move along a specific trajectory. During this process, the first adjustment roller 4 and the second adjustment roller 8 cooperate closely to provide stable support from the inner and outer sides of the arc plate, and play an auxiliary guiding role, which effectively avoids the arc plate from shaking or deflecting during movement, and ensures the stability and accuracy of the movement of the arc plate; with the help of the synergistic effect of the first adjustment roller 4, the second adjustment roller 8 and the grinding assembly, the end position of the arc plate is continuously adjusted in the process of gradually approaching the adjacent arc plate, and finally, the end of the arc plate is accurately aligned with the end of the adjacent arc plate, ensuring the position accuracy of the subsequent welding operation; When the end of the arc plate squeezes the grinding plate 13, the gas spring rod 12 expands and contracts according to the squeezing force, and adjusts the contact force between the grinding plate 13 and the arc plate. During the grinding process, the squeezing force applied by the arc plate is transmitted through the grinding plate 13, so that the piston rod 15 drives the piston plate 16 to slide in the piston cylinder 14, causing the gas pressure in the piston cylinder 14 to change. When the gas pressure in the piston cylinder 14 increases, the driving plate 19 moves upward, pushing the sleeve 18 to move upward, and driving the piston cylinder 14 and other components to move upward together; when the sleeve 18 moves up to a specific position, the air outlet pipe 21 is connected to the inside of the piston cylinder 14, and the gas is discharged. Under the action of the first spring 17 and the second spring 37, the sleeve 18 and related components reset and move downward, and this cycle is repeated to achieve the up and down reciprocating movement of the piston cylinder 14, thereby enhancing the grinding effect; As the arc plate moves, when it reaches a specific position and breaks away from the extrusion contact with the grinding plate 13, the first spring 17 rebounds and drives the piston plate 16 to return to its original position. At this time, the one-way air inlet valve 30 is closed, and the one-way air outlet valve 29 is opened. The gas in the piston cylinder 14 enters the connecting pipe 31 through the one-way air outlet valve 29, and then passes through the air jet pipe 32 and the air jet nozzle 33 to the welding surface of the arc plate after grinding, blowing away debris and impurities to ensure that the welding surface is clean; Under the continuous drive of the driving component, when the end of the arc-shaped plate comes into exact contact with the end of the adjacent arc-shaped plate, a series of operations such as alignment, grinding, and cleaning of the grinding surface have been completed. After the position of the welding torch 36 is adjusted appropriately, the welding device is started. The robotic arm 35 drives the welding torch 36 to move according to the preset welding path and parameters, and performs welding operations on the adjacent arc-shaped plates to complete the splicing and welding operations of the flange.
