Description

Technical Field

[0001] This invention belongs to the technical field of welding processing mechanisms, specifically relating to a gas-specific ultra-high temperature and high pressure metal flexible connection and welding processing mechanism. Background Technology

[0002] A gas-specific ultra-high temperature and high pressure metal flexible connection and welding processing mechanism is a key flexible connection component for conveying special gases under extreme working conditions (such as ultra-high temperature and pressure). It is made of high temperature resistant alloy material and processed by precision welding process. It has excellent sealing performance, fatigue resistance and corrosion resistance. It is widely used in high pressure pipeline systems in aerospace, energy and chemical industries to compensate for displacement and vibration and ensure safe and reliable gas transmission.

[0003] However, traditional devices still have the following problems when in use: Patent application publication number CN120023577B discloses an automatic welding processing equipment for thin-walled metal hoses. The operator adjusts the position of the positioning component and the slide block in the guide rail according to the position of the welding components. The positioning component and the clamping inner support component clamp and fix the metal hose and the connector respectively. The clamping inner support component clamps the connector and supports it inside the metal hose at the same time, so as to provide stable support for the welding position of the metal hose. This prevents the hose inside the connector from deforming and failing to fit with the inner wall of the connector when the connector is sleeved on the outside of the metal hose and the two are welded by the welding components, which would cause the welding point to deviate.

[0004] In the existing technology, when welding equipment welds a flange to a metal hose, it usually only fixes the position of the flange without effectively positioning the metal hose. When the rotating mechanism drives the flange and the metal hose to rotate, the metal hose is prone to shaking due to the lack of constraint, which leads to positional deviation or unstable welding trajectory during the welding process, affecting the uniformity and aesthetics of the weld and reducing the welding quality. Therefore, we need a special ultra-high temperature and high pressure metal flexible connection and welding processing mechanism for gas to solve the problem of unsecured metal hoses and to fix the metal hoses.

[0015] A gas-specific ultra-high temperature and high pressure metal flexible joint is realized based on a gas-specific ultra-high temperature and high pressure metal flexible welding processing mechanism. The gas-specific ultra-high temperature and high pressure metal flexible joint includes the following steps: S1: Placement and initial fixing: Place the metal hose body and flange to be welded in the rotating frame on the operating table, and use the fixing mechanism of the rotating frame to fix the flange. S2: Adjust welding angle: Start the motor on one side of the welding equipment body, adjust the angle of the operating table, so that the metal hose body, the flange to be welded position, and the welding gun body are at the optimal relative angle. S3: Start support mechanism: The water pump is turned on by the controller, so that the water in the cooling tank enters the bag through the buffer tank and hose. The bag expands and pushes the fixing plate to contact the inner wall of the metal hose body for support. The water pump stops after the pressure sensor detects that the pressure reaches the standard. S4: Adjust the heat dissipation mechanism: Rotate the threaded rod to drive the fixed seat one, the force rod and the force ring to move.

[0033] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1 to 15 This invention provides a technical solution for a gas-specific ultra-high temperature and high pressure metal soft welding processing mechanism: it includes a welding equipment body 1, a welding gun body 11 on the welding equipment body 1, an operating table 12 rotatably connected to the welding equipment body 1, a rotating frame 13 rotatably connected inside the operating table 12, a clamping mechanism on the rotating frame 13, a flange 15 in movable contact with the clamping mechanism, a metal hose body 14 fixedly connected inside the two flanges 15, a base 2 fixedly connected to the welding equipment body 1, a cooling box 21 fixedly connected to the outer wall of the top of the base 2, an installation hole with two connected sides on the base 2, a water pump 22 fixedly connected inside the installation hole, the input end of the water pump 22 penetrating and fixedly connected to the inside of the cooling box 21, a second fixed seat 29 fixedly connected to the inner wall of the rotating frame 13, and a support mechanism fixedly connected to the second fixed seat 29.

[0035] By starting the motor on one side of the welding equipment body 1, the angle of the operating table 12 can be adjusted so that the welding position and the position of the welding gun body 11 are at the optimal angle, which facilitates the operation of the welding gun body 11.

[0036] In Embodiment Two, based on Embodiment One, the support mechanism includes a fixed bracket 28. The outer wall of the fixed bracket 28 is fixedly connected to the inner wall of the fixed base 29. A buffer tank 23 is fixedly connected to the output end of the water pump 22. A flexible hose 24 is fixedly connected to the lower side of one side of the buffer tank 23. A fixed shell 6 is rotatably connected to the lower side of the outer wall of the fixed bracket 28. A cavity 63 is formed inside the fixed shell 6. The outer wall of one end of the flexible hose 24 is fixedly connected to the interior of the cavity 63. A flow channel 212 is formed inside the fixed bracket 28. A through hole 65 is formed at the lower side of the inner wall of the flow channel 212. The outer wall of one side of the through hole 65 is connected to the interior of the cavity 63, allowing flow... A connecting pipe 26 is connected through the upper part of the inner wall of the first tube 212. A bag 27 is fixedly connected to the outer wall of the fixed bracket 28. The outer wall of one end of the connecting pipe 26 is fixedly connected through the inside of the bag 27. A fixing plate 25 is fixedly connected to the outer wall of the bag 27. The outer wall of one side of the four fixing plates 25 is in movable contact with the inner wall of the metal hose body 14. A pressure sensor 211 is embedded in the outer wall of the fixing plate 25. Ball bearings 61 are fixedly connected to the inner walls of the upper and lower sides of the fixed shell 6. The inner ring walls of the two ball bearings 61 are fixedly connected to the outer wall of the fixed bracket 28. A sealing ring 62 is fixedly connected to the inner wall of the fixed shell 6. The inner ring walls of the three sealing rings 62 are in movable contact with the outer wall of the fixed bracket 28.

[0037] The setting of the fixing plate 25 and the bag 27 provides a support point for the metal hose body 14, which avoids the metal hose body 14 from shaking when rotating. Correspondingly, it prevents the metal hose body 14 from shifting position or the welding trajectory from being unstable during the welding process, which affects the uniformity and aesthetics of the weld, thereby improving the welding quality of the metal hose body 14 and the flange 15. In Example 3, based on Example 2, telescopic rods 210 are fixedly connected to the upper and lower sides inside the fixed bracket 28, and the outer wall of one end of the multiple telescopic rods 210 is fixedly connected to the outer wall of the other side of the fixed plate 25.

[0038] Since the telescopic rod 210 is composed of a fixed sleeve and a sliding rod, the movement path of the fixed plate 25 is limited by the cooperation of the sliding rod and the fixed sleeve, so as to prevent the fixed plate 25 from deviating during the movement. Since the movement path of the fixed plate 25 is stable and there will be no deviation, it can more stably support the metal hose body 14.

[0039] In Example 4, based on Example 3, a piston 52 is movably inserted into the inner wall of the top of the flow channel 212, and a pressure spring 51 is fixedly connected to the outer wall of the top of the piston 52. A cavity 3 is opened inside the fixed bracket 28 above the flow channel 212. The inner wall of the top of the cavity 3 is fixedly connected to the outer wall of one end of the pressure spring 51. A limit ring 5 is fixedly connected to the inner wall of the cavity 3. The outer wall of the bottom of the limit ring 5 is in movable contact with the outer wall of the top of the piston 52.

[0040] When piston 52 moves to limit ring 5, piston 52 stops moving. At this time, piston 52 is above telescopic tube 31. The water flow that enters cavity 3 then enters cavity 4 341 through telescopic tube 31. This intelligent water flow path switching mechanism automatically guides the water flow into a new heat dissipation path when the water flow can no longer provide support for the expansion of bag 27, providing the basic conditions for heat dissipation of fixed plate 25.

[0041] In Example 5, based on Example 4, a telescopic tube 31 is fixedly connected through the inner wall of cavity 3. The outer wall of one end of the four telescopic tubes 31 is fixedly connected through the upper part of the interior of the fixed plate 25. Cavity 4 341 is opened inside the fixed plate 25. A flow guide plate 34 is fixedly connected inside cavity 4 341. A cylindrical hole is opened at the bottom of the inner wall of cavity 4 341. A telescopic tube 2 33 is fixedly connected through the bottom of the cylindrical hole. A flow channel 2 32 is opened inside the fixed bracket 28 outside the flow channel 1 212. The outer wall of one end of the four telescopic tubes 2 33 is fixedly connected through the interior of flow channel 2 32. A through hole 2 66 is opened on the inner wall of one side of flow channel 2 32. Cavity 2 64 is opened inside the fixed shell 6. The inner wall of cavity 2 64 is fixedly connected through the outer wall of one end of through hole 2 66. A flexible hose 2 3 is fixedly connected through the inner wall of cavity 2 64. The outer wall of one end of flexible hose 2 3 is fixedly connected through the interior of the cooling box 21.

[0042] Since the cavity 341 is located above the connection between the metal hose body 14 and the flange 15, it does not dissipate heat at the welded joint of the metal hose body 14 and the flange 15. Instead, it removes heat from the area above the welded joint of the metal hose body 14 and the flange 15. This localized heat dissipation method avoids the disorderly diffusion of heat to other parts of the metal hose body 14 and effectively controls the range of heat propagation. The design of this invention avoids heat dissipation at the welded joint and instead removes heat from the area above the welded joint, preventing the heat generated by high-temperature welding from being excessively transferred to the entire metal hose body 14, thereby protecting the welded joint and the overall structural integrity of the metal hose body 14.

[0043] In Example 6, based on Example 5, a circular hole is provided at the middle of the top of the fixed bracket 28. A nut 41 is fixedly connected inside the circular hole. A threaded rod 4 is threadedly connected inside the nut 41. A fixed seat 42 is rotatably connected to the bottom outer wall of the threaded rod 4. A force-bearing rod 43 is fixedly connected to the outer wall of the fixed seat 42. The outer wall of the force-bearing rod 43 slides through the interior of the cavity 3. A force-bearing ring 44 is fixedly connected to the opposite side of the two force-bearing rods 43. The outer wall of the bottom of the force-bearing ring 44 is in contact with the outer wall of the top of the piston 52.

[0044] As the force ring 44 moves away from the piston 52, the rotation of the threaded rod 4 can be stopped when the force ring 44 moves above the cavity. Through the cooperation between the threaded rod 4 and the force ring 44, the opening of the heat dissipation mechanism can be freely adjusted, making the heat dissipation mechanism flexible. The operator can decide whether to open the heat dissipation mechanism according to the on-site situation.

[0045] Example 7: A gas-specific ultra-high temperature and high pressure metal flexible connection is implemented based on a gas-specific ultra-high temperature and high pressure metal flexible welding processing mechanism from Examples 1 to 5. This gas-specific ultra-high temperature and high pressure metal flexible connection includes the following steps: S1: Placement and initial fixing: Place the metal hose body 14 and flange 15 to be welded in the rotating frame 13 on the operating table 12, and use the fixing mechanism of the rotating frame 13 to fix the flange 15. The flange 15 is fixed by the fixing mechanism of the rotating frame 13 to prevent the flange 15 from moving during subsequent operations and to ensure the stability of the relative position of the flange 15 and the metal hose body 14 during welding.

[0046] S2: Adjust the welding angle: Start the motor on one side of the welding equipment body 1, and adjust the angle of the operating table 12 so that the metal hose body 14 and the flange 15 to be welded and the welding gun body 11 are at the best relative angle. An optimal angle helps the welding gun body 11 better control the weld pool, resulting in a more uniform and aesthetically pleasing weld formation, reducing welding defects, and thus improving the welding quality between the metal hose body 14 and the flange 15. S3: Start the support mechanism: Turn on the water pump 22 through the controller so that the water in the cooling tank 21 enters the bag 27 through the buffer tank 23 and the hose 24. The bag 27 expands and pushes the fixing plate 25 to contact and support the inner wall of the metal hose body 14. After the pressure sensor 211 detects that the pressure reaches the standard, the water pump 22 stops. To prevent the metal hose body 14 from shaking and causing positional deviation or unstable welding trajectory during the welding process, which would affect the uniformity and aesthetics of the weld, and to ensure that the welding process can be carried out according to the predetermined trajectory and parameters, thereby improving the accuracy and consistency of the welding.

[0047] S4: Adjust the heat dissipation mechanism: Rotate the threaded rod 4 to drive the fixed seat 42, the force rod 43 and the force ring 44 to move. Move the force ring 44 to the top of the cavity 3 to open the heat dissipation mechanism, or move it to the top of the piston 52 to close the heat dissipation mechanism. When the cooling mechanism is not required, the force ring 44 is moved above the piston 52 and contacts the piston 52 to apply pressure to the piston 52, preventing the piston 52 from being blown open by the water pressure inside the bag 27. This increases the stability of the piston 52 and protects the relevant components of the cooling mechanism.

[0048] S5: Complete welding and cooling cycle: Weld the metal hose body 14 and flange 15. The heat generated by welding is absorbed by the cold water in cavity 341. The cold water is circulated back to cooling box 21 through a series of channels to achieve continuous heat dissipation. The cold water circulates back to the cooling tank 21 through a series of channels. The movement of the water pump 22 keeps the cold water circulating, ensuring that the cold water can continuously remove heat, avoid heat accumulation, significantly improve heat dissipation efficiency, and provide a relatively stable temperature environment for the welding process.

[0049] The working principle and usage process of this invention are as follows: During operation, firstly, the metal hose body 14 and flange 15 to be welded are placed inside the rotating frame 13 on the operating table 12. Then, the flange 15 is fixed by the fixing mechanism set on the rotating frame 13. By starting the motor on one side of the welding equipment body 1, the angle of the operating table 12 can be adjusted so that the welding position and the position of the welding gun body 11 are at the optimal angle, which facilitates the operation of the welding gun body 11. The above are the conventional working principles of the welding equipment body 1, which will not be elaborated here.

[0050] This invention uses a controller to start a water pump 22, which delivers water from the cooling tank 21 to the buffer tank 23 via its output. Due to the fixed connection between the buffer tank 23 and the hose 24, after entering the buffer tank 23, the water flows through the buffer tank 23 into the hose 24, then through the hose 24 to the cavity 63, and finally through the through hole 65 into the flow channel 212. Because of the fixed connection between the flow channel 212 and the connecting pipe 26, and because the other end of the connecting pipe 26 is connected to the inside of the bag 27, the water flows into the bag 27 through the connecting pipe 26 after reaching the top of the flow channel 212. After water enters the bladder 27, it expands, which pushes the fixing plate 25 to contact and support the inner wall of the metal hose body 14. When the pressure received by the pressure sensor 211 reaches the preset value, it transmits the detected information to the controller. Upon receiving the signal, the controller immediately controls the water pump 22 to stop running. The setting of the fixing plate 25 and the bladder 27 provides a support point for the metal hose body 14, preventing the metal hose body 14 from shaking when rotating. Correspondingly, it prevents the metal hose body 14 from shifting position or the welding trajectory from being unstable during the welding process, which would affect the uniformity and aesthetics of the weld, thereby improving the welding quality of the metal hose body 14 and the flange 15.

[0051] It should be noted that the telescopic nature of hose 23 and hose 124 will not affect the adjustment of the angle of the metal hose body 14 driven by the operating table 12.

[0052] It should be noted that a miniature solenoid valve is fixedly connected to the outer wall of the fixed bracket 28 below the bag 27. One end of the miniature solenoid valve is fixedly connected to the lower part of the inner wall of the bag 27, and the other end is connected to the upper part of the inside of the flow channel 2 32. The solenoid valve is opened by the controller, so that the water inside the bag 27 flows into the inside of the flow channel 2 32, and finally is discharged into the inside of the cooling box 21 through the hose 2 3.

[0053] In this invention, telescopic rods 210 are fixedly connected to both the upper and lower ends of one side of the fixed plate 25, and the other end of the telescopic rods 210 is fixedly connected to the inside of the fixed bracket 28. Since the telescopic rods 210 are composed of a fixed sleeve and a sliding rod, when the pouch 27 expands and pushes the fixed plate 25 to move, the movement of the fixed plate 25 will cause the sliding rod to slide outward inside the fixed sleeve. Through the cooperation of the sliding rod and the fixed sleeve, the movement path of the fixed plate 25 is limited, preventing the fixed plate 25 from deviating during movement. Since the movement path of the fixed plate 25 is stable and there is no deviation, it can more stably support the metal hose body 14.

[0054] This invention allows the operator to rotate the threaded rod 4. Due to the threaded connection between the threaded rod 4 and the nut 41, the threaded rod 4 moves upward or downward along the threaded path of the nut 41 when it rotates. The rotational connection between the threaded rod 4 and the fixed seat 42 prevents the fixed seat 42 from rotating simultaneously. The upward or downward movement of the threaded rod 4 causes the fixed seat 42 to move accordingly. Furthermore, the fixed connection between the fixed seat 42 and the force-bearing rod 43 causes the force-bearing rod 43 to move the force-bearing ring 44 upward when the fixed seat 42 moves. This causes the force-bearing ring 44 to move away from above the piston 52. When the force-bearing ring 44 moves above the cavity 3, the rotation of the threaded rod 4 can be stopped. Through the cooperation of the threaded rod 4 and the force-bearing ring 44, the opening of the heat dissipation mechanism can be freely adjusted, giving the heat dissipation mechanism flexibility. The operator can then decide whether to activate the heat dissipation mechanism based on the situation on site.

[0055] Before fixing the metal hose body 14, if the heat dissipation mechanism needs to be turned on, the force ring 44 can be moved to the top of the cavity three. If the heat dissipation mechanism does not need to be turned on, the force ring 44 can be moved to the top of the piston 52 and contact the piston 52, thereby applying pressure to the piston 52 and preventing the piston 52 from being blown open by the water pressure inside the bag 27, thus increasing the stability of the piston 52.

[0056] When the force-bearing ring 44 is above the cavity three, water flows through the flow channel 212 into the interior of the connecting pipe 26, and then through the connecting pipe 26 into the interior of the bladder 27. After the bladder 27 is fully inflated, as the water continues to flow into the flow channel 212, the water inside the flow channel 212 can no longer enter the interior of the connecting pipe 26. At this time, the water will push the piston 52 upward, and then the piston 52 will move upward, applying a compressive force to the pressure spring 51. The pressure spring 51 is compressed by the compressive force, thereby causing the piston 52 to slide upward into the cavity three. When the piston 52 moves to the limit ring 5, the piston 52 stops moving. At this time, the piston 52 is located above the telescopic pipe 31. At this point, the water flowing into cavity three enters cavity four 341 through telescopic tube one 31. This intelligent water flow path switching mechanism automatically guides the water flow into a new heat dissipation path when the water flow can no longer provide support for the expansion of the bag 27, providing a basic condition for the heat dissipation of the fixing plate 25. The water flows along the path of the diversion plate 34 set inside cavity four 341, thereby driving the heat on the fixing plate 25, avoiding the heat of the metal hose body 14 from being transferred to the fixing plate 25. The heat on the fixing plate 25 is carried away by cold water, reducing the heat damage to the fixing plate 25, and correspondingly extending the service life of the fixing plate 25, reducing the maintenance cost and replacement frequency of the fixing plate 25.

[0057] This invention utilizes the contact between the fixing plate 25 and the metal hose body 14. When cold water flows inside the cavity 341, it not only absorbs heat from the fixing plate 25 but also carries away heat from the metal hose body 14 in contact with the fixing plate 25. The cavity 341 is located above the connection between the metal hose body 14 and the flange 15, preventing heat dissipation at the welded joint. The heat carried away is limited to the area above the welded joint. This localized heat dissipation method avoids the disorderly diffusion of heat to other parts of the metal hose body 14, effectively controlling the range of heat propagation. The design of this invention avoids heat dissipation at the welding point, instead removing heat above the welding point to prevent excessive heat from the high-temperature welding from being transferred to the entire metal hose body 14. This protects the overall structural integrity of the welding point and the metal hose body 14. Metal materials are prone to creep, fatigue, and other damage in high-temperature environments, leading to decreased strength and shortened lifespan. By timely removing heat above the welding point between the metal hose body 14 and the flange 15, the temperature of this part is reduced, reducing thermal damage to the metal hose body 14 material and slowing down the aging process of the material, thereby extending the service life of the metal hose body 14.

[0058] In this invention, when the cold water moves downward inside the cavity 341, it enters the telescopic tube 33 through the cylindrical hole. Due to the through connection between the telescopic tube 33 and the flow channel 32, the water flows into the interior of the flow channel 32 through the telescopic tube 33, and then enters the interior of the cavity 64 through the through hole 66 provided below the flow channel 32. Finally, it is discharged into the interior of the cooling tank 21 through the hose 3. The movement of the water pump 22 causes the cold water to circulate, ensuring that the cold water can continuously remove heat, avoiding heat accumulation, and significantly improving heat dissipation efficiency.

[0059] By setting up a fixed shell 6 and a ball bearing 61, the present invention keeps the fixed shell 6 stationary when the fixed bracket 28 rotates due to the rotational connection between the fixed shell 6 and the fixed bracket 28. This solves the problem that the second hose 3 and the first hose 24 need to rotate with the fixed bracket 28, eliminates the risk of torsional damage, and extends the service life of the second hose 3 and the first hose 24.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
