Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic field coupling test equipment, in particular to a slender pipe fixture tooling used for electromagnetic field coupling processing. Background Art

[0002] Energy is an important foundation for maintaining and promoting economic and social development. China is facing the challenge of energy development. Although fossil fuels are still the main source of energy, the environmental and health problems they bring are becoming increasingly prominent. Therefore, the demand for clean, efficient and safe energy has become more urgent. In this context, nuclear energy, as a resource-rich and low-carbon energy form, has attracted much attention. With the continuous growth of the economy and the continuous increase in electricity demand, it is crucial to enhance the contribution of nuclear power generation. As one of the important components of nuclear power plants, the performance of steam generators directly affects the efficiency and safety of nuclear power generation. Among them, nickel-based heat transfer tubes, as a key component of steam generators, are crucial for their thermal conductivity and high temperature and high pressure resistance. At present, the actual heat exchange efficiency of heat transfer tubes in use in my country is about 70% to 85% of the design value, and there is still considerable room for improvement.

[0003] Special energy field assisted manufacturing technology is a material strengthening technology that involves applying physical energy fields (such as electric fields, magnetic fields or acoustic fields, etc.) to the entire manufacturing life cycle of the processed metal or alloy, covering processes such as metallurgy, material modification, remanufacturing and damage repair. This technology uses the characteristics of physical energy fields to change the microstructure of the processed material, thereby achieving the purpose of regulating its material properties. Among them, electric field treatment and magnetic field treatment, also known as electromagnetic coupling treatment, are the most widely studied and have the highest practicality. Nickel-based alloys are ferromagnetic materials, and electromagnetic coupling treatment technology has a significant regulatory effect on them. In the experiment of using electromagnetic coupling technology to improve the thermal conductivity of nickel-based heat transfer tubes, the design of the fixture is a very important component. The fixture used in the traditional electromagnetic coupling treatment process needs to simultaneously realize the conduction of the electric field and the clamping of the processed parts, so as to perform electromagnetic coupling treatment on the parts clamped by the fixture.

[0004] However, the length-to-diameter ratio of nickel-based heat transfer tubes is relatively large. During electromagnetic coupling processing, the operator needs to adjust the clamping position of the fixture on the workpiece multiple times, which affects the efficiency of the coupling processing. In addition, as the clamping position changes, the center of gravity of the pipe fittings is uneven due to the inconsistent lengths on both sides of the fixture, which can easily cause the pipe fittings in the clamping position of the fixture to tilt and affect the electromagnetic coupling.

[0005] Therefore, it is necessary to provide a fixture design for electromagnetic coupling processing of slender pipes / rods (nickel-based heat transfer tubes) to solve the above technical problems. Utility Model Content

[0019] Furthermore, a second auxiliary supporting device is fixedly provided on the base at a side of the movable supporting device away from the first auxiliary supporting device, and a fourth clamping channel for the pipe to pass through and coaxial with the first clamping channel is opened on the second auxiliary supporting device.

[0020] Furthermore, balls are arranged on the inner walls of the third clamping channel and the fourth clamping channel, and the balls are in rolling contact with the outer wall of the pipe.

[0021] Furthermore, it also includes a temperature detection mechanism, which includes an infrared thermometer, and the infrared thermometer is arranged just below the electromagnetic clamping end.

DETAILED DESCRIPTION

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example 1

[0032] The present application embodiment discloses a slender pipe 8 fixture used for electromagnetic field coupling processing, referring to Figure 1 , including a base, on which a movable support device 2, an electromagnetic clamping end 1 and a first auxiliary support device 3 are sequentially arranged. Two electromagnetic clamping ends 1 are provided, and the two electromagnetic clamping ends 1 are arranged opposite to each other. A groove for fitting the outer wall of the pipe 8 is provided on the side facing each other of the two electromagnetic clamping ends 1. After the two electromagnetic clamping ends 1 are close to each other and abutted, a first clamping channel 11 for the pipe 8 to pass through is formed between the two electromagnetic clamping ends 1. The electromagnetic clamping ends 1 can conduct an electric field, and a magnetic field is formed by an additional electromagnetic device, so that the pipe 8 between the electromagnetic clamping ends 1 can be electromagnetically coupled.

[0033] Reference Figure 2, a second clamping channel 21 for the pipe 8 to pass through and coaxial with the first clamping channel 11 is provided on the movable support device 2, and a clamping device for fixing the pipe 8 is provided on one side of the second clamping channel 21. The first auxiliary support device 3 is a door-shaped frame, and a third clamping channel 31 adapted to the shape of the pipe 8 and used to support the pipe 8 is provided on the top of the frame, and the third clamping channel 31 is coaxial with the first clamping channel 11. When the nickel-based alloy heat transfer tube is subjected to electromagnetic coupling treatment, the pipe 8 is passed through the first clamping channel 11 and the second clamping channel 21 at the same time, and the clamping device clamps and fixes the pipe 8. The two electromagnetic clamping ends 1 start from the end of the pipe 8 to perform electromagnetic coupling treatment on the pipe 8. After a section of the pipe 8 is processed, the pipe 8 is moved one way for a section, and the pipe 8 is continued to be processed. When the pipe 8 is moved a long distance, it passes through the third clamping channel 31. The movable supporting device 2 and the first auxiliary supporting device 3 support the pipe 8 on both sides of the electromagnetic clamping end 1, thereby ensuring the coaxiality of the pipe 8 in the first clamping channel 11.

[0034] The electromagnetic clamping end 1 includes a hydraulic push electrode head and a power transmission component. The hydraulic push electrode head is installed on the power transmission component. The material selected for the hydraulic push electrode head is brass, which has good conductivity, excellent heat dissipation and non-magnetic concentration characteristics. The nickel-based alloy heat transfer tube to be treated is clamped by two hydraulic push electrode heads, and a pulse electric field can be applied to the pipe 8 to be treated.

[0035] Specifically, the clamping assembly includes a clamping outer ring 22, a clamping rod 23, and a fixed block 24. The clamping ring is coaxially rotatably connected to the outer side of the second clamping channel 21 on the movable support device 2. The fixed block 24 and the clamping rod 23 are evenly spaced along the axial direction of the clamping ring in at least three groups. The fixed block 24 is rotatably connected to the clamping ring. One end of the clamping rod 23 is hinged to the movable support device 2, and the other end passes through the fixed block 24 and extends into the clamping ring to contact the outer wall of the pipe 8. The clamping rod 23 slides along its own length direction and is inserted into the fixed block 24. The movable support device 2 is provided with a driving component for driving the clamping outer ring 22 to rotate. After the clamping outer ring 22 is driven to rotate by the driving component, the fixed block 24 on the clamping outer ring 22 moves in a circle. During the movement, the fixed block 24 rotates, and the clamping rod 23 slides in the clamping block, so that the channel size formed by the ends of the three clamping rods 23 in the second clamping channel 21 becomes larger / smaller, thereby loosening / clamping the pipe fitting 8.

[0036] In the embodiment of the present application, the driving component is a hydraulic cylinder 25, the cylinder body of the hydraulic cylinder 25 is hinged to the movable support device 2, and the piston rod is hinged to the outer wall of the clamping ring. In other embodiments, the driving component can also be a driving motor, a coaxial gear ring is provided on the clamping outer ring 22, the clamping outer ring 22 is rotatably mounted on the movable support device 2, and the driving motor drives the clamping outer ring 22 to rotate forward / reverse through the gear.

[0037] The cylinder body of the hydraulic cylinder 25 is connected to a hydraulic system, and the movement of the piston rod of the hydraulic cylinder 25 is controlled by the hydraulic system. There is a pressure gauge on the hydraulic clamping assembly. The magnitude of the clamping force can be transmitted to the host computer in real time through the relationship between the pressure gauge, torque and clamping force, so as to realize real-time adjustment of the hydraulic force. Specifically, the magnitude of the torque force applied to the clamping outer ring 22 can be known through the magnitude of the hydraulic pressure displayed by the hydraulic system, and the magnitude of the torque force and the clamping force on the clamping wheel 26 can be known through the balance relationship, so as to realize the monitoring of the clamping force and prevent the fixture from damaging the parts. At the same time, when the pipe 8 generates magnetically induced vibration during the electromagnetic coupling process of the pipe 8, the hydraulic system can be adjusted in real time according to the monitoring of the clamping force to adjust the clamping force.

[0038] Furthermore, the hydraulic system is provided with an anti-vibration device, which can be any one of a buffer, a shock absorbing valve, and a hydraulic damper provided in the hydraulic system oil circuit. The anti-vibration function of the hydraulic system is mainly achieved in the following ways:

[0039] 1. Buffer: The commonly used buffer in hydraulic system can absorb and buffer the shock and vibration in the mechanical system by introducing an adjustment device in the oil circuit. This adjustment device is usually composed of a piston, liquid and air;

[0040] 2. Shock absorber valve: The shock absorber valve in the hydraulic system can control the pressure and speed in the mechanical system by regulating the flow of liquid, thereby reducing vibration and impact;

[0041] 3. Hydraulic damper: Hydraulic damper slows down and suppresses the vibration and impact of mechanical system by introducing damping force in the hydraulic system.

[0042] Furthermore, one end of the clamping rod 23 extending into the clamping ring is rotatably connected to a clamping wheel 26, and the clamping rod 23 is in rolling contact with the outer wall of the pipe 8 through the clamping wheel 26. The material of the clamping wheel 26 is a non-metallic and highly elastic material, such as rubber, so that the clamping wheel 26 is non-conductive, so that only the electromagnetic clamping end 1 is conductive, and at the same time, the pipe 8 can be flexibly clamped to protect the parts from being damaged by clamping.

[0043] Furthermore, a track is provided on the base along the axial direction of the first clamping channel 11, the movable support device 2 is slidably connected to the track, and a driving member for driving the movable support device 2 to move is provided on the base. In an embodiment of the present application, the driving member includes a linear module 4 provided on the base, and the movable support device 2 is fixedly provided on a linear slide of the linear module 4. The linear module 4 can be a linear module 4 driven by a screw rod, or a linear module 4 driven by a synchronous belt. Through the linear module 4, after the clamping device is controlled by the host computer program to release the pipe 8, the movable support device 2 moves an end distance, clamps the pipe 8 again and drives the pipe 8 forward, thereby realizing continuous segmented feeding of the pipe 8 and improving the efficiency of electromagnetic coupling processing of the pipe 8.

[0044] Furthermore, a second auxiliary support device 5 is fixedly provided on the side of the movable support device 2 away from the first auxiliary support device 3 on the base. The second auxiliary support device 5 has the same structure as the first auxiliary support device 3. The first auxiliary support device 3 and the second auxiliary support device 5 are respectively located at the two ends of the base. The second auxiliary support device 5 is provided with a fourth clamping channel 51 for the pipe 8 to pass through and coaxial with the first clamping channel 11. When the movable support device 2 changes to clamp different positions on the pipe 8, the second auxiliary support device 5 supports the pipe 8, thereby improving the placement stability of the pipe 8 and ensuring the coaxiality of the clamping assembly on the movable support device 2 to clamp the pipe 8.

[0045] Furthermore, balls 6 are provided on the inner walls of the third clamping channel 31 on the first auxiliary supporting device 3 and the fourth clamping channel 51 on the second auxiliary supporting device 5. The balls 6 are in rolling contact with the outer wall of the pipe fitting 8. When the pipe fitting 8 is fed on the clamping tooling, the friction between the pipe fitting 8 and the balls 6 is reduced, and the outer wall of the pipe fitting 8 can be scratched on the surface, thereby providing better protection for the pipe fitting 8 when the clamped pipe fitting 8 is moved.

[0046] Furthermore, a temperature detection mechanism 7 is included. In the embodiment of the present application, the temperature detection mechanism 7 includes an infrared thermometer. Specifically, a frame is installed on the base at the lower end of the two electromagnetic clamping ends 1, and the infrared thermometer is fixedly installed on the frame, located directly below the first clamping channel 11 between the two battery clamping ends. The infrared thermometer can transmit the temperature of the electromagnetic clamping end 1 to the host computer, and can realize real-time monitoring and early warning of the part temperature. When the temperature exceeds the warning value, the operator can stop the field processing in time to avoid damage to the pipe 8 caused by excessive temperature.

[0047] Example 2

[0048] The present application discloses a method for using a fixture for an elongated pipe 8 used in electromagnetic field coupling processing, comprising the following steps:

[0049] Step S1, installation. Install one end of the nickel-based alloy heat transfer pipe to be processed on the movable support device 2, and place the other end on the second auxiliary support device 5. Turn on the upper computer to control the linear module 4 to make the movable support device 2 return to one end close to the nickel-based heat transfer pipe, and then control the electromagnetic clamping end 1 to clamp the parts to complete the installation of the parts.

[0050] Among them, the specific material of the nickel-based alloy heat transfer tube of this scheme is 690 nickel-based alloy, with a size of Φ17.48mm (outer diameter) × 1.02mm (thickness) × 500mm (height). It is a tubular part with a relatively large length-to-diameter ratio. The nickel-based alloy heat transfer tube is made by smelting - forging - hot extrusion - cold processing - heat treatment.

[0051] Step S2, pretreatment. Start the electromagnetic coupling treatment device, and apply pulse electric field and pulse magnetic field to the pipe 8 through the two electromagnetic clamping ends 1 to perform electromagnetic coupling treatment on the material. The high-frequency and high-magnetic field strength pulse magnetic field is used to treat the magnetoplasticity of ferromagnetic metal materials. The pulse magnetic field weakens the binding ability between electron pairs, and the interaction force between dislocations and obstacles is weakened or eliminated, providing a driving force for the depinning of metal micro dislocations; then the high-frequency and high-voltage pulse electric field is used to treat the electroplasticity of metal materials. The pulse current mainly provides an electronic driving force for the movement of metal micro dislocations through the Joule heating effect, the skin effect and the pure electroplastic effect.

[0052] Step S3, segmented processing. First, control the electromagnetic clamping end 1 to loosen, and ensure that the clamping assembly on the movable support device 2 clamps the pipe 8, and then control the linear module 4 to drive the movable support device 2 to move (the moving distance is the width of the electromagnetic clamping end 1). Re-control the electromagnetic clamping end 1 to clamp the pipe 8, and repeat the above pretreatment process to process the pipe 8. Among them, the part that the movable support device 2 starts to clamp needs to be manually changed before the pretreatment work of this part can be carried out.

[0053] Step S4, clamping force detection and temperature monitoring. The magnitude of the torque force applied to the clamping outer ring 22 can be known through the magnitude of the hydraulic pressure displayed by the hydraulic system, and the magnitude of the torque force on the clamping wheel 26 and the magnitude of the clamping force can be known through the balance relationship, so as to monitor the clamping force and prevent the clamp from damaging the pipe 8. At the same time, when magnetic vibration is generated, the hydraulic system can be adjusted in real time according to the monitoring of the clamping force to adjust the clamping force.

[0054] The high-temperature infrared thermometer is fixed just below the electromagnetic clamping end 1. The high-temperature infrared thermometer can transmit the temperature of the electromagnetic clamping end 1 to the host computer, so as to realize real-time monitoring and early warning of the part temperature. When the temperature exceeds the warning value, the operator can stop the field processing in time to avoid damage to the curved parts caused by excessive temperature.
