[0036] Embodiment 1

[0037] Refer to Figures 1 - 8, this embodiment discloses a processing system and process for components of a natural gas regenerative heating furnace. First, a processing system for components of a natural gas regenerative heating furnace is described, including a conveying device 1. In this solution, the conveying device 1 includes a conveying platform 110, which is strip-shaped, and a plurality of conveying rollers 120 are arranged along the length direction of the conveying platform 110. The regenerative chamber outer plate 5 is conveyed on the upper surface of the conveying rollers 120. The strip-shaped conveying platform 110 can transport multiple regenerative chamber outer plates 5 at the same time. Above the conveying device 1 (that is, above the conveying platform 110) and in sequence along its conveying direction, there are a hole-cutting station 2, a first welding station 3, and a second welding station 4. Through the conveying device 1, multiple regenerative chamber outer plates 5 can be sequentially conveyed directly below the hole-cutting station 2, the first welding station 3, and the second welding station 4, enabling processes such as cutting and welding of the regenerative chamber outer plates 5 to be completed on the same production line.

[0038] First, in combination with Figure 2 and Figure 3 , as an implementation manner provided in this embodiment, the hole-cutting station 2 includes a hole-cutting device 21. In this solution, a plasma cutting machine is used to penetrate and cut a hole channel 51 on the surface of the regenerative chamber outer plate 5. Moreover, in this solution, the hole channel 51 is circular, and the plasma cutting machine needs to be driven to rotate for cutting. Among them, the hole-cutting station 2 further includes a first support plate 22. A first motor 23 is installed at the bottom of the first support plate 22. The output end of the first motor 23 is connected to a first gear 24, and a second gear 25 meshes with it. The lower end of the second gear 25 is connected to the hole-cutting device 21, and the upper end is slidably connected to the first support plate 22 through a first bracket 26. An annular groove is opened on the first support plate 22. The first bracket 26 is clamped with the annular groove and can rotate around the annular groove. When cutting the hole channel 51, the first motor 23 drives the first gear 24 to rotate, drives the second gear 25 to rotate through meshing, and then drives the hole-cutting device 21 to rotate to complete the cutting. It should be noted that within the rotation circumference of the hole-cutting device 21, no conveying rollers 120 are provided at this position on the conveying platform to avoid damaging the conveying rollers 120, and a waste box 12 is provided below this position, so that the waste generated by hole-cutting can fall into the waste box 12.

[0039] Based on the above structure, since the side of the heat storage outer plate 5 facing the hole cutting device 21 is used to install the pipe seat 6, the hole cutting position needs to be polished. The first gear 24 also meshes with a third gear 27, and an electric grinding machine 28 capable of lifting is connected to the lower end of the third gear 27. The upper end is slidably connected to the first frame plate 22 through a second bracket 29. The second bracket 29 is also slidably installed in the annular groove of the first frame plate 22. The electric grinding machine 28 realizes lifting movement through components such as a driving motor. After the hole cutting is completed, the electric grinding machine 28 is controlled to descend and contact the outside of the hole 51, and under the drive of the first motor 23, the hole 51 is polished flat in a circle.

[0040] In the above hole cutting - grinding structure, driving the second gear 25 and the third gear 27 to rotate circumferentially simultaneously by the first gear 24 is an optimized design of the present invention, which has the advantages of good directivity and controllable working sequence. However, it is easy to understand that the above structure can also be realized in other forms as long as the hole cutting - grinding operation of the present invention can be realized and the processing requirements are met. In addition, in this embodiment, the first frame plate 22 is preferably designed as a liftable frame plate to improve the flexibility of adjustment. Similarly, as an alternative means, the hole cutting device 21 can also have a liftable cutting head.

[0041] Regarding the design of the first welding station 3 of this solution, in combination with Figure 4 , the first welding station 3 includes a first welding device 31 for welding the pipe seat 6 to the periphery of the hole 51. The first welding device 31 is installed on a first driving component, and the first driving component is used to drive the first welding device 31 to move circumferentially. Among them, the first driving component includes a second frame plate 32, and a second motor 33 is installed at the upper end of the second frame plate 32. The first welding device 31 is installed at the bottom of the second frame plate 32 and is eccentrically installed relative to the second motor 33, which is convenient for the welding end of the first welding device 31 to extend to the position where the pipe seat 6 is connected to the heat storage outer plate 5. And the first welding device 31 adopts a laser welding device, and the welding head extends to the contact position between the pipe seat 6 and the heat storage outer plate 5. The first welding station 3 is for welding the pipe seat 6. During welding, the pipe seat 6 is placed above the hole 51, the first welding device 31 is started, and the first welding device 31 is driven to rotate in cooperation with the second motor 33, and one - week rotation around the bottom of the pipe seat 6 is completed for welding. Similarly, although not shown in the figure, the second motor 33 in this embodiment is also preferably installed on a liftable frame plate.

[0042] After the welding of the pipe seat 6 is completed, the welding of the air duct 7 is carried out at the second welding station 4. Moreover, the difference between this solution and the prior art is that in order to solve the positioning problem during the welding process, the air duct 7 is welded first and then cut. Among them, in combination with Figures 5 - 7, the second welding station 4 includes a second welding device 41 and a cutting device 42. The second welding device 41 is a laser welding device, and its output end extends towards the connection position of the air duct 7 and the pipe seat 6. The cutting device 42 is a laser cutting device, and its output end extends towards the air duct 7. The second welding device 41 is used to weld the air duct 7 and the pipe seat 6. In this solution, the cutting device 42 is used to cut the welded air duct 7 according to the required size. Since the welding of the air duct 7 and the pipe seat 6 and the cutting of the air duct 7 both need to be completed by rotating one circle, in order to optimize the spatial layout to the greatest extent in this embodiment, the second welding device 41 and the cutting device 42 are jointly installed on the second driving assembly, and the second driving assembly can drive the second welding device 41 and the cutting device 42 to move circumferentially, enabling the second welding device 41 and the cutting device 42 to rotate and complete the welding and cutting operations.

[0043] Among them, the second driving assembly includes a third support plate 43, and a third motor 44 is installed at the bottom of the third support plate 43. The output end of the third motor 44 is connected to a fourth gear 45, and the fourth gear 45 is meshed with an external gear ring 46. The form of using the external gear ring 46 instead of a gear is to facilitate the air duct 7 to pass through the middle of the external gear ring 46. The upper end of the external gear ring 46 is connected to a connecting rod 47. In this solution, at least two connecting rods 47 are provided, and the connecting rod 47 is slidably clamped with the third support plate 43. That is, an annular groove is opened on the end face of the third support plate 43 where the connecting rod 47 is installed, and the connecting rod 47 extends into the annular groove, which is the same as the connection method between the first support and the annular groove, and can be clamped with the annular groove and can also rotate along the annular groove. Secondly, a turntable 49 is connected to the lower end of the external gear ring 46 through a support rod 48. At least two support rods 48 are also provided, and both the second welding device 41 and the cutting device 42 are fixedly connected to the turntable 49. When the third motor 44 is started, it drives the fourth gear 45 to rotate, and then drives the turntable 49 to rotate through the meshing with the external gear ring 46, and finally drives the second welding device 41 and the cutting device 42 to perform circular motion.

[0044] As Figure 8 shown, it is a schematic diagram of the components of the natural gas regenerative heating furnace after welding and cutting.

[0045] It should be noted that, since the air duct 7 in this solution is first welded and then cut, the cutting position of the air duct 7 needs to be cut according to the required length. Therefore, the cutting device 42 needs to be able to move in the vertical direction. Therefore, the second driving assembly is connected with a lifting assembly for driving the cutting device 42 to lift along the air duct 7. Among them, the lifting assembly includes a telescopic cylinder 9 connected to the upper end surface of the third frame plate 43, and a telescopic rod 10 is connected to the upper end of the third frame plate 43. By setting the telescopic cylinder 9, the third frame plate 43 can be driven to move up and down, and then the cutting device 42 can be driven to move up and down. At the same time, by setting the telescopic rod 10, the balance and stability of the movement of the third frame plate 43 can be improved, and the cutting device 42 can be driven to move to the cutting position of the required length of the air duct 7 for cutting action.

[0046] In this solution, the air duct 7 is docked with the upper end of the pipe seat 6 in a vertical feeding manner. A feeding device 8 is arranged above the second welding station 4, and the feeding device 8 can clamp the air duct 7 and drive the air duct 7 to move up and down to dock with the pipe seat 6. Among them, the feeding device 8 includes clamping and feeding rollers, and it can clamp the air duct 7 and drive the air duct 7 to move up and down to achieve docking with the pipe seat 6 and separation after cutting. Moreover, a through hole 11 for the air duct 7 to pass through is opened in the middle of the third frame plate 43, as Figure 6 shown.

[0047] Since the pipe body of the air duct 7 is relatively thin, in this embodiment, the method of welding first and then cutting is adopted. During welding, good auxiliary positioning can be carried out with the help of the feeding device 8, thus well solving the problem of difficult positioning of thin pipes.

[0048] Embodiment 2

[0049] On the basis of Embodiment 1, this embodiment further provides a processing technology for components of a natural gas regenerative heating furnace. According to the processing system for components of a natural gas regenerative heating furnace introduced in Embodiment 1, this technology specifically includes the following steps:

[0050] S1: Transmit the regenerative outdoor plate 5 to the lower part of the hole cutting station 2 through the transmission device 1, start the hole cutting device 21 and the first motor 23 to cut out a hole channel 51 on the surface of the regenerative outdoor plate 5. The first motor 23 drives the hole cutting device 21 to rotate through the meshing of the first gear 24 and the second gear 25 to complete circumferential cutting. After cutting is completed, the first motor 23 and the hole cutting device 21 are turned off. Control the electric grinding machine 28 to descend to contact the hole channel 51 and start it. At the same time, start the first motor 23 to polish the circumference of the hole channel 51. After polishing is completed, turn off the first motor 23 and the electric grinding machine 28 and drive the electric grinding machine 28 to rise and reset.

[0051] S2: The conveying device 1 transports the heat storage outer plate 5 with the holes 51 drilled to the position below the first welding station 3, places the pipe seat 6 at the holes 51 of the heat storage outer plate 5, and keeps it coaxial with the holes 51. Start the first welding device 31 and the second motor 33. The second motor 33 drives the first welding device 31 to rotate around the pipe seat 6 to weld and fix it to the heat storage outer plate 5, drives the first welding device 31 to weld around the bottom of the pipe seat 6 for one circle to complete the fixation. After welding, drive the first welding device 31 to move to the rear side in the moving direction of the heat storage outer plate 5 and turn off the second motor 33 and the first welding device 31.

[0052] S3: The conveying device 1 transports the heat storage outer plate 5 welded with the pipe seat 6 to the position below the second welding station 4. The clamping and feeding rollers of the feeding device 8 convey the air duct 7 downward to be butted against the upper end of the pipe seat 6. Start the second welding device 41 and the third motor 44. Through the meshing of the fourth gear 45 and the external gear ring 46, drive the second welding device 41 to rotate, so that the third motor 44 drives the second welding device 41 to rotate around the contact position between the pipe seat 6 and the air duct 7 for one week to weld and fix the two. After welding, turn off the third motor 44 and the second welding device 41.

[0053] S4: The telescopic cylinder 9 of the lifting assembly drives the cutting device 42 to move to the position to be cut of the air duct 7. Start the cutting device 42 and the third motor 44. Through the meshing of the gears, the third motor 44 drives the cutting device 42 to rotate around the air duct 7 for one week to cut off the air duct 7. As Figure 8 shown, it is a schematic diagram of the heat storage outer plate 5 welded with the pipe seat 6 and the air duct 7. After cutting, the feeding device 8 drives the air duct 7 to move upward away from the cutting position.

[0054] S5: The conveying device 1 moves the heat storage outer plate 5 welded with the air duct 7 to the blanking station for blanking, completing the welding work of one heat storage outer plate 5 and the air duct 7.

[0055] Moreover, this solution can enable multiple heat storage outer plates 5 to be processed simultaneously at different stations. Therefore, the distance between the axes of the output ends of the first motor 23 and the second motor 33 is not less than the length of the heat storage outer plate 5, and the minimum distance between the axis of the output end of the second motor 33 and the center line of the external gear ring 46 is not less than the length of the heat storage outer plate 5. That is to ensure that after one heat storage outer plate 5 finishes processing at this station and moves to the next station, the subsequent heat storage outer plate 5 can move to this station, and the two heat storage outer plates 5 perform different station processing actions synchronously, improving the processing efficiency of the heat storage outer plate 5. Preferably, the above steps are automatically run through the program of the control system to achieve full-process automation.

[0056] As described above, it is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
