DETAILED DESCRIPTION

[0036] Example 1

[0037] See also Figure 1-Figure 8The present embodiment discloses a processing system and process for a natural gas thermal storage heating furnace component, wherein firstly, a processing system for a natural gas thermal storage heating furnace component is described, including a conveying device 1. In the present scheme, the conveying device 1 includes a conveying platform 110, which is in an elongated shape, and a plurality of conveying rollers 120 are arranged along the length direction of the conveying platform 110. The outer panels 5 of the thermal storage chamber are placed on the upper surface of the conveying rollers 120 for conveying. The elongated conveying platform 110 can simultaneously transport a plurality of thermal storage chamber outer panels 5. A cutting station 2, a first welding station 3, and a second welding station 4 are sequentially arranged above the conveying device 1 (that is, above the conveying platform 110) and along its conveying direction. The conveying device 1 can sequentially convey a plurality of thermal storage chamber outer panels 5 to the bottom of the cutting station 2, the first welding station 3, and the second welding station 4, so that the cutting and welding processes of the thermal storage chamber outer panels 5 can be completed on the same production line.

[0038] First, combine Figure 2 and Figure 3 As an implementation method provided in this embodiment, the hole cutting station 2 includes a hole cutting device 21. This solution adopts a plasma cutting machine to penetrate and cut a hole 51 on the surface of the outer plate 5 of the heat storage chamber. In this solution, the hole 51 is circular and needs to drive the plasma cutting machine for rotation cutting. The hole cutting station 2 also includes a first frame plate 22. A first motor 23 is installed at the bottom of the first frame plate 22. The output end of the first motor 23 is connected to a first gear 24, and it is meshed with a second gear 25. The lower end of the second gear 25 is connected to the hole cutting device 21, and the upper end is connected to the first bracket 2 6 is slidably connected to the first frame plate 22, an annular groove is provided on the first frame plate 22, the first bracket 26 is engaged with the annular groove and can rotate around the annular groove, when cutting the channel 51, the first motor 23 drives the first gear 24 to rotate, drives the second gear 25 to rotate through engagement, and then drives the hole cutting device 21 to rotate to complete the cutting, and it should be noted that within the rotating circumference of the hole cutting device 21, the conveying roller 120 is not set at this position on the conveying platform to avoid damage to the conveying roller 120, and a waste box 12 is set below this position, and the waste generated by the hole cutting can fall into the waste box 12.

[0039] On the basis of the above structure, since the side of the outer plate 5 of the heat storage chamber 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 is also meshed with the third gear 27, and the lower end of the third gear 27 is connected to an electric grinder 28 that can be lifted and lowered, and the upper end is slidably connected to the first frame plate 22 through the second bracket 29, and the second bracket 29 is also slidably installed in the annular groove of the first frame plate 22. The electric grinder 28 is lifted and lowered by driving components such as the motor, so that after the hole cutting is completed, the electric grinder 28 is controlled to descend and contact the outside of the channel 51, and a circle of the channel 51 is polished and smooth under the drive of the first motor 23.

[0040] In the above-mentioned hole cutting and grinding structure, the first gear 24 drives the second gear 25 and the third gear 27 to rotate circumferentially at the same time as the optimized design of the present invention, which has the advantages of good guidance and controllable working sequence, but it is easy to understand that the above-mentioned structure can also be implemented in other forms as long as the hole cutting and grinding operation of the present invention can be realized and the processing requirements can be 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. As an alternative means, the hole cutting device 21 can also have a liftable cutting head.

[0041] The design of the first welding station 3 is as follows: Figure 4 , the first welding station 3 includes a first welding device 31, which is used to weld the pipe seat 6 to the side of the hole 51, and the first welding device 31 is installed on the first driving assembly, and the first driving assembly is used to drive the first welding device 31 to move circumferentially, wherein the first driving assembly includes a second frame plate 32, and a second motor 33 is installed on 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, so that the welding end of the first welding device 31 is conveniently extended to the position where the pipe seat 6 is connected to the outer plate 5 of the thermal storage chamber, 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 outer plate 5 of the thermal storage chamber, and the first welding station 3 is for welding the pipe seat 6. When welding, the pipe seat 6 is placed above the hole 51, the first welding device 31 is started, and the second motor 33 is used to drive the first welding device 31 to rotate, and the welding is completed by rotating around the bottom of the pipe seat 6. Similarly, although not shown in the figure, the second motor 33 in this embodiment is also preferably installed on the lifting frame.

[0042] After the pipe seat 6 is welded, the air duct 7 is welded at the second welding station 4. The difference between this solution and the prior art is that, in order to solve the positioning problem during welding, the air duct 7 is welded first and then cut. Figure 5-Figure 7The 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 toward the position where the air duct 7 and the pipe seat 6 are connected. The cutting device 42 is laser cutting, and its output end extends toward the air duct 7. The second welding device 41 is used to weld the air duct 7 to 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 to the pipe seat 6 and the cutting of the air duct 7 both require one circle of rotation to complete, in order to maximize the spatial layout of the oil painting, the second welding device 41 and the cutting device 42 are installed together on the second driving assembly in this embodiment, and the second driving assembly can drive the second welding device 41 and the cutting device 42 to move circumferentially, so that the second welding device 41 and the cutting device 42 can rotate to complete the welding and cutting actions.

[0043] Among them, the second driving assembly includes a third frame plate 43, and a third motor 44 is installed at the bottom of the third frame plate 43. The output end of the third motor 44 is connected to a fourth gear 45, and the fourth gear 45 is meshedly connected with an outer gear ring 46. The outer gear ring 46 is provided to replace the gear in order to facilitate the air duct 7 to pass through the middle of the outer gear ring 46. The upper end of the outer gear ring 46 is connected to a connecting rod 47. In this solution, at least two connecting rods 47 are provided, and the connecting rods 47 are slidably engaged with the third frame plate 43, that is, a ring-shaped end surface of the third frame plate 43 where the connecting rod 47 is installed is provided. The connecting rod 47 extends into the annular groove, which is consistent with the connection method between the first bracket and the annular groove, and can be snap-fitted with the annular groove and can also rotate along the annular groove. Secondly, a turntable 49 is connected to the lower end of the outer gear ring 46 through a support rod 48. At least two support rods 48 are also provided, and the second welding device 41 and the cutting device 42 are both fixedly connected to the turntable 49. When the third motor 44 is started, the fourth gear 45 is driven to rotate, and then the turntable 49 is driven to rotate through engagement with the outer gear ring 46, and finally the second welding device 41 and the cutting device 42 are driven to make circular motion.

[0044] like Figure 8 The figure shows a schematic diagram of the natural gas thermal storage heating furnace components after welding and cutting.

[0045] It should be noted that, since the present solution adopts the method of welding first and then cutting the air duct 7, the cutting position of the air duct 7 needs to be cut according to the required length, so 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, which is used to drive the cutting device 42 to rise and fall along the air duct 7, wherein the lifting assembly includes a telescopic cylinder 9 connected to the upper end surface of the third frame plate 43, and the upper end of the third frame plate 43 is connected to a telescopic rod 10. 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, the telescopic rod 10 is set to improve the balance and stability of the movement of the third frame plate 43, and drive the cutting device 42 to move to the cutting position of the required length of the air duct 7 for cutting.

[0046] In this solution, the air duct 7 is connected to the upper end of the pipe seat 6 by vertical feeding. A feeding device 8 is provided 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 connect with the pipe seat 6. The feeding device 8 includes a clamping feeding roller, which 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. In addition, a through hole 11 for the air duct 7 to pass through is opened in the middle of the third frame plate 43, such as Figure 6 shown.

[0047] Since the air duct 7 is relatively thin, the present embodiment adopts a method of welding first and then cutting, and can assist in positioning with the aid of the feeding device 8 during welding, thereby effectively solving the problem of poor positioning of thin tubes.

[0048] Example 2

[0049] This embodiment further provides a processing technology for a natural gas thermal storage heating furnace component on the basis of Embodiment 1. According to the processing system for the natural gas thermal storage heating furnace component introduced in Embodiment 1, this process specifically includes the following steps:

[0050] S1: The outer plate 5 of the heat storage chamber is conveyed to the bottom of the hole cutting station 2 via the conveying device 1, and the hole cutting device 21 and the first motor 23 are started to cut a hole 51 on the surface of the outer plate 5 of the heat storage chamber. The first motor 23 drives the hole cutting device 21 to rotate through the engagement of the first gear 24 and the second gear 25 to complete the circumferential cutting. After the cutting is completed, the first motor 23 and the hole cutting device 21 are turned off, and the electric grinder 28 is controlled to descend to contact with the hole 51 and started. At the same time, the first motor 23 is started to grind the hole 51 circumferentially. After the grinding is completed, the first motor 23 and the electric grinder 28 are turned off and the electric grinder 28 is driven to rise and reset.

[0051] S2: The conveying device 1 conveys the heat storage chamber outer plate 5 with the hole 51 to the bottom of the first welding station 3, places the pipe seat 6 at the hole 51 of the heat storage chamber outer plate 5, and keeps it coaxial with the hole 51, starts the first welding device 31 and the second motor 33, and the second motor 33 drives the first welding device 31 to rotate around the pipe seat 6 to weld it to the heat storage chamber outer plate 5, drives the first welding device 31 to weld around the bottom of the pipe seat 6 for a circle to complete the fixation, and after the welding is completed, drives the first welding device 31 to move to the rear side of the moving direction of the heat storage chamber outer plate 5 and turns off the second motor 33 and the first welding device 31.

[0052] S3: The conveying device 1 conveys the outer plate 5 of the heat storage chamber for welding the pipe seat 6 to the bottom of the second welding station 4, and the clamping feeding roller of the feeding device 8 conveys the air duct 7 downward to dock with the upper end of the pipe seat 6, and the second welding device 41 and the third motor 44 are started. The second welding device 41 is driven to rotate through the meshing of the fourth gear 45 and the outer gear ring 46, so that the third motor 44 drives the second welding device 41 to circle around the contact position between the pipe seat 6 and the air duct 7 for one circle, and the two are welded and fixed. After the welding is completed, the third motor 44 and the second welding device 41 are turned off.

[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, starts the cutting device 42 and the third motor 44, and drives the cutting device 42 to circle around the air duct 7 through the meshing of the gears, so as to cut the air duct 7. Figure 8 As shown, it is a schematic diagram of the completion of welding of the outer plate 5 of the heat storage chamber, 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 chamber outer plate 5 welded with the air duct 7 to the unloading station for unloading, completing the welding work of the heat storage chamber outer plate 5 and the air duct 7.

[0055] Moreover, this solution enables multiple heat storage room outer panels 5 to be processed simultaneously at different workstations. Therefore, the distance between the output end axes of the first motor 23 and the second motor 33 is not less than the length of the heat storage room outer panel 5, and the minimum distance between the output end axis of the second motor 33 and the center line of the outer gear ring 46 is not less than the length of the heat storage room outer panel 5. That is, it is ensured that after one heat storage room outer panel 5 is processed at this workstation and moved to the next workstation, the next heat storage room outer panel 5 can be moved to this workstation, and the two heat storage room outer panels 5 are processed synchronously at different workstations, thereby improving the processing efficiency of the heat storage room outer panel 5. Preferably, the above steps are automatically run by the program of the control system to achieve full process automation.
