Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and particularly relates to an automatic pressure curing furnace for high-speed rail skateboards and a curing method thereof. Background Art

[0002] The high-speed rail skateboard is the source of power for high-speed rail and the only component connecting the high-speed rail and the high-voltage catenary. Due to the high operating speed and harsh operating conditions of high-speed rail, the self-performance requirements of high-speed rail skateboards are relatively high. The main performances of high-speed rail skateboards include resistivity, airtightness, impact resistance, friction performance, etc. The main production processes of high-speed rail skateboards include bending, punching, bonding, curing, assembly, etc. Among them, the quality of the curing performance of high-speed rail skateboards is the key factor affecting their bonding physical properties, resistivity and other performances.

[0003] In order to ensure the curing performance during the curing process of high-speed rail skateboards, it is usually necessary to apply a certain clamping force to the carbon strip and bracket of the high-speed rail skateboard bonded together through an artificial control clamping tool before curing, so that the carbon strip and bracket of the high-speed rail skateboard are stressed and bonded; however, during the curing process, the adhesive in the glue layer between the carbon strip and bracket of the high-speed rail skateboard will cure and shrink, resulting in a decrease in the overall thickness of the high-speed rail skateboard. Since the clamping degree of the clamping tool before curing is fixed, when the overall thickness of the high-speed rail skateboard decreases, the clamping force of the clamping tool on the high-speed rail skateboard will decrease or fail, resulting in a poor bonding effect between the carbon strip and bracket of the high-speed rail skateboard, and further affecting the curing performance of the high-speed rail skateboard. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic pressure curing furnace for high-speed rail skateboards and a curing method thereof to improve the curing performance of high-speed rail skateboards.

[0005] To achieve the above purpose, in the first aspect, the present invention provides an automatic pressure curing furnace for high-speed rail skateboards, including:

[0006] A furnace body, in which a bearing structure for carrying high-speed rail skateboards is arranged;

[0007] A heating device, arranged in the furnace body, for heating the high-speed rail skateboards;

[0008] A pressure applying device, installed on the furnace body, for applying pressure to the high-speed rail skateboards so that the high-speed rail skateboards are clamped between the pressure applying device and the bearing structure;

[0009] A pressure detection device, for detecting the real-time pressure value applied to the high-speed rail skateboards by the pressure applying device;

[0010] A control system is installed on the furnace body. The heating device, the pressurizing device, and the pressure detection device are all connected to the control system. The control system is used to control the heating device to heat the high-speed rail slide plate and to control the pressurizing device to apply pressure to the high-speed rail slide plate according to the real-time pressure value.

[0011] In the case of adopting the above technical solution, before curing, the pressurizing device can be controlled by the control system to apply pressure to the high-speed rail slide plate first, and then the heating device can be controlled by the control system to heat the high-speed rail slide plate for curing. During the curing process, the real-time pressure value applied by the pressurizing device to the high-speed rail slide plate can be detected by the pressure detection device, and then the control system can control the pressurizing device to apply pressure to the high-speed rail slide plate according to the real-time pressure value in real time, so that during the curing process, the control system can adjust the pressure applied by the pressurizing device to the high-speed rail slide plate in real time, thereby adjusting the clamping force received by the carbon strip and the bracket of the high-speed rail slide plate in real time. Furthermore, when the adhesive in the glue layer between the carbon strip and the bracket of the high-speed rail slide plate shrinks during curing, resulting in a reduction in the overall thickness of the high-speed rail slide plate, the control system can adjust the pressure applied by the pressurizing device to the high-speed rail slide plate in real time to ensure good clamping effect between the carbon strip and the bracket of the high-speed rail slide plate, and further ensure good bonding effect between the carbon strip and the bracket of the high-speed rail slide plate, thereby improving the curing performance of the high-speed rail slide plate. In addition, when the control system controls the heating device to heat the high-speed rail slide plate and controls the pressurizing device to apply pressure to the high-speed rail slide plate, the curing efficiency can be improved.

[0012] In some possible implementation manners, the control system includes a pressure program controller, which is connected to the pressure detection device. A preset holding pressure and a preset holding time are set in the pressure program controller. The pressure program controller is used to adjust the pressure value applied by the pressurizing device to the high-speed rail slide plate in real time according to the magnitude relationship between the real-time pressure value and the preset holding pressure to ensure that the pressure value applied by the pressurizing device to the high-speed rail slide plate is in a stable state. With this setting, the pressure program controller ensures that the pressure value applied by the pressurizing device to the high-speed rail slide plate is in a stable state, further improving the curing performance of the high-speed rail slide plate.

[0013] In some possible implementation manners, the pressurizing device includes a hydraulic station, a hydraulic pipe, a hydraulic cylinder, and a pressing member connected in sequence. The hydraulic cylinder is installed on the furnace body. The hydraulic station supplies fluid to the hydraulic cylinder through the hydraulic pipe. When the telescopic shaft of the hydraulic cylinder expands and contracts under the action of the fluid, it drives the pressing member to move and apply pressure to the high-speed rail slide plate;

[0014] The hydraulic station includes a hydraulic control valve, an oil pressure buffer tank, an oil pump, an oil pressure gauge, an oil pressure sensor, a hydraulic solenoid valve, and a hydraulic station control box. The pressure program controller is connected to the hydraulic station control box to control the pressure value applied by the pressing member to the high-speed rail slide plate to be in a stable state through the hydraulic station control box. With this setting, hydraulic pressurization can be achieved through the cooperation of the hydraulic station, the hydraulic pipe, the hydraulic cylinder, and the pressing member.

[0015] In some possible implementation manners, the bearing structure includes a clamping assembly. The clamping assembly includes an upper pressing member, a spring, and a lower pressing member. A spring groove is provided inside the upper pressing member, and the spring is located in the spring groove. The high-speed rail slide plate is located between the lower pressing member and the spring. When the upper pressing member and the lower pressing member move relative to each other, the lower pressing member presses the spring through the high-speed rail slide plate, causing the spring to deform. With such a setting, by pressing the high-speed rail slide plate against the spring, it is convenient to adjust the pressure received by the high-speed rail slide plate in real time through the spring.

[0016] In some possible implementation manners, a first positioning groove with an upward opening is provided at the upper part of the upper pressing member, and a second positioning groove with a downward opening is provided at the lower part of the lower pressing member. The high-speed rail slide plate is positioned within the first positioning groove and the second positioning groove, and the spring groove communicates with the first positioning groove;

[0017] When the lower pressing member moves into contact with the upper pressing member, there is a spacing between the high-speed rail slide plate and the bottom surface of the first positioning groove, and the spacing is a fixed value. With such a setting, the high-speed rail slide plate is limited by the first positioning groove and the second positioning groove, making the installation of the high-speed rail slide plate more stable; when there is a spacing between the high-speed rail slide plate and the bottom surface of the first positioning groove, it can prevent the surface of the high-speed rail slide plate from being damaged after contacting the bottom surface of the groove.

[0018] In some possible implementation manners, the bearing structure further includes a frame body, and a plurality of clamping assemblies are provided on the frame body;

[0019] There are a plurality of frame bodies, and the plurality of frame bodies are arranged in sequence in the vertical direction, and the plurality of clamping assemblies are arranged in a stacked manner in sequence in the vertical direction. With such a setting, multiple high-speed rail slide plates can be stacked and placed through the bearing structure, improving the operation efficiency.

[0020] In some possible implementation manners, it further includes a temperature detection device for detecting the real-time temperature value of the environment around the high-speed rail slide plate;

[0021] The control system is connected to the temperature detection device and is used to adjust the heating temperature of the heating device in real time according to the real-time temperature value. With such a setting, it is convenient to precisely control the temperature in the furnace.

[0022] In some possible implementation manners, there are a plurality of temperature detection devices, and the plurality of temperature detection devices are evenly distributed in the vertical direction. With such a setting, it is convenient to ensure the uniformity of the temperature in the furnace.

[0023] In some possible implementation manners, it further includes an exhaust device and a blast device. A partition cover is provided inside the furnace body. The high-speed rail slide plate is located inside the partition cover. The exhaust device is communicated with the inside of the partition cover, and the blast device is arranged outside the partition cover. Ventilation holes are provided on the partition cover; the air blown out by the blast device passes through the ventilation holes and flows into the inside of the partition cover, and is discharged through the exhaust device. With such a setting, it is convenient to ventilate the furnace.

[0024] In some possible implementations, a heat insulation and heat preservation cover is sleeved outside the partition cover, and the air blowing device is used to blow air into the space between the heat insulation and heat preservation cover and the partition cover;

[0025] The heating device includes electric heating tubes located between the heat insulation and heat preservation cover and the partition cover. The air blown by the air blowing device passes through the electric heating tubes and is heated, then flows into the interior of the partition cover through the ventilation holes and is discharged through the exhaust device. With such a setting, it is convenient to heat the high-speed rail skateboard with hot air and improve the uniformity of heating.

[0026] In some possible implementations, the exhaust device includes an exhaust fan, an exhaust valve, an exhaust duct, and a purification and filtration box. The exhaust fan is connected to the exhaust duct, the exhaust valve is used to control the exhaust air volume in the exhaust duct, and the purification and filtration box is used to purify the air flow discharged from the exhaust duct;

[0027] The control system is connected to the exhaust valve and is used to control the exhaust air volume of the exhaust device through the exhaust valve. With such a setting, the purification and filtration degree of the exhaust device is improved.

[0028] In a second aspect, the present invention also provides a curing method for an automatic pressure curing furnace, including the automatic pressure curing furnace for high-speed rail skateboards provided in any one of the above solutions. The curing method includes:

[0029] Clamping the high-speed rail skateboard in the curing furnace;

[0030] Heating and curing the high-speed rail skateboard in the curing furnace;

[0031] According to the actual clamping force received by the high-speed rail skateboard during the curing process, the clamping degree of the high-speed rail skateboard is adjusted in real time so that the actual clamping force received by the high-speed rail skateboard remains stable during the curing process.

[0032] With the above technical solutions, since the automatic pressure curing furnace for high-speed rail skateboards in the present application is adopted, the curing performance of the high-speed rail skateboard can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] As Figures 1 to 6 shown, the present invention provides an automatic pressure-curing furnace for high-speed rail skateboards, which includes a furnace body 1, a heating device 2, a pressure-applying device 3, a pressure detection device, and a control system 4. A bearing structure 8 for carrying the high-speed rail skateboard 11 is provided inside the furnace body 1; the heating device 2 is arranged inside the furnace body 1 and is used for heating the high-speed rail skateboard 11; the pressure-applying device 3 is installed on the furnace body 1 and is used for applying pressure to the high-speed rail skateboard 11 so that the high-speed rail skateboard 11 is clamped between the pressure-applying device 3 and the bearing structure 8; the pressure detection device is used for detecting the real-time pressure value applied to the high-speed rail skateboard 11 by the pressure-applying device 3; the control system 4 is installed on the furnace body 1, and the control system 4 is connected to the heating device 2 and the pressure-applying device 3 and is used for controlling the heating device 2 to heat the high-speed rail skateboard 11 and for controlling the pressure-applying device 3 to apply pressure to the high-speed rail skateboard 11 according to the real-time pressure value. Among them, the pressure detection device is an existing sensor capable of detecting pressure.

[0048] In the case of adopting the above technical solution, before curing, the pressure applying device 3 can be controlled by the control system 4 to apply pressure to the high-speed rail skateboard 11 first, and then the heating device 2 can be controlled by the control system 4 to heat the high-speed rail skateboard 11 for curing. During the curing process, the real-time pressure value applied by the pressure applying device 3 to the high-speed rail skateboard 11 can be detected by the pressure detection device, and then the control system 4 can control the pressure applying device 3 to apply pressure to the high-speed rail skateboard 11 in real time according to the real-time pressure value, so that during the curing process, the control system 4 can adjust the pressure applied by the pressure applying device 3 to the high-speed rail skateboard 11 in real time, thereby adjusting the clamping force received by the carbon strip and the bracket of the high-speed rail skateboard 11 in real time. Furthermore, when the adhesive in the glue layer between the carbon strip and the bracket of the high-speed rail skateboard 11 cures and shrinks during the curing process, resulting in a reduction in the overall thickness of the high-speed rail skateboard 11, the control system 4 can adjust the pressure applied by the pressure applying device 3 to the high-speed rail skateboard 11 in real time to ensure good clamping effect between the carbon strip and the bracket of the high-speed rail skateboard 11, and further ensure good bonding effect between the carbon strip and the bracket of the high-speed rail skateboard 11, thereby improving the curing performance of the high-speed rail skateboard 11. In addition, when the heating device 2 is controlled by the control system 4 to heat the high-speed rail skateboard 11 and the pressure applying device 3 is controlled to apply pressure to the high-speed rail skateboard 11, the curing efficiency can be improved.

[0049] In some embodiments, the control system 4 includes a pressure program controller, which is connected to the pressure detection device. A preset pressure holding value and a preset pressure holding time are set in the pressure program controller. The pressure program controller is used to adjust the pressure value applied by the pressure applying device 3 to the high-speed rail skateboard 11 in real time according to the magnitude relationship between the real-time pressure value and the preset pressure holding value, so as to ensure that the pressure value applied by the pressure applying device 3 to the high-speed rail skateboard 11 is in a stable state. Among them, the pressure program controller is an existing program controller for controlling pressure. The pressure detection device transmits the detected real-time pressure value to the pressure program controller. The pressure program controller compares the magnitude relationship between the real-time pressure value and the preset pressure holding value. When the real-time pressure value is greater than the preset pressure holding value, the pressure program controller controls the pressure applying device 3 to reduce the pressure value applied to the high-speed rail skateboard 11 and maintains the preset pressure holding time; when the real-time pressure value is less than the preset pressure holding value, the pressure program controller controls the pressure applying device 3 to increase the pressure value applied to the high-speed rail skateboard 11 and maintains the preset pressure holding time. With this structure, the pressure program controller ensures that the pressure value applied by the pressure applying device 3 to the high-speed rail skateboard 11 is in a stable state, further improving the curing performance of the high-speed rail skateboard 11.

[0050] Such as Figures 1 to 3As shown in the figure, the pressing device 3 includes a hydraulic station 34, a hydraulic pipe 31, a hydraulic cylinder 32, and a pressing member 33 that are connected in sequence. The hydraulic cylinder 32 is installed on the furnace body 1. The hydraulic station 34 supplies fluid to the hydraulic cylinder 32 through the hydraulic pipe 31. When the telescopic shaft of the hydraulic cylinder 32 expands and contracts under the action of the fluid, it drives the pressing member 33 to move and apply pressure to the high-speed rail slide plate 11. The hydraulic station 34 includes a hydraulic control valve, an oil pressure buffer tank, an oil pump, an oil pressure gauge, an oil pressure sensor, a hydraulic solenoid valve, and a control box of the hydraulic station 34. The pressure program controller is connected to the control box of the hydraulic station 34 to control the pressure value applied by the pressing member 33 to the high-speed rail slide plate 11 to be in a stable state through the control box of the hydraulic station 34. Among them, the pressing member 33 includes a connecting rod and a pressing plate perpendicular to the connecting rod. The connecting rod is connected to the telescopic shaft of the hydraulic cylinder 32. The hydraulic control valve is used to control the flow rate of the fluid. The oil pressure buffer tank is used to store the oil fluid. The oil pump is used to control the oil fluid transportation. The oil pressure gauge is used to display the pressure of the oil fluid. The oil pressure sensor is used to detect the pressure of the oil fluid. The pressure detection device in this embodiment is the oil pressure sensor. The hydraulic solenoid valve is used to control the flow and cut-off of the oil fluid. The control box of the hydraulic station 34 is used to control the detection and movement of each component. With this structure, hydraulic pressing can be achieved through the cooperation of the hydraulic station 34, the hydraulic pipe 31, the hydraulic cylinder 32, and the pressing member 33. The transportation control of the oil fluid can be achieved through the hydraulic control valve, the oil pressure buffer tank, the oil pump, the oil pressure gauge, the oil pressure sensor, the hydraulic solenoid valve, and the control box of the hydraulic station 34.

[0051] As Figures 1 to 6 shown, in some embodiments, the bearing structure 8 includes a clamping assembly. The clamping assembly includes an upper pressing member 82, a spring 84, and a lower pressing member 83. A spring groove is provided inside the upper pressing member 82. The spring 84 is located in the spring groove. The high-speed rail slide plate 11 is located between the lower pressing member 83 and the spring 84. When the upper pressing member 82 and the lower pressing member 83 move relative to each other, the lower pressing member 83 squeezes the spring 84 through the high-speed rail slide plate 11, causing the spring 84 to deform. Among them, the opening of the spring groove faces the lower pressing member 83. One side of the high-speed rail slide plate 11 contacts the lower pressing member 83, and the other side contacts the spring 84. With this structure, by pressing the high-speed rail slide plate 11 against the spring 84, it is convenient to balance the pressure applied by the pressing device to the high-speed rail slide plate 11, so that the high-speed rail slide plate 11 can adjust the pressure it receives in real time through the spring 84 during the curing process, thereby keeping the pressure received by the high-speed rail slide plate 11 stable and further improving the curing performance of the high-speed rail slide plate 11. At the same time, during the relative movement of the upper pressing member 82 and the lower pressing member 83, by continuously applying a supporting force to the high-speed rail slide plate 11 through the spring 84, the high-speed rail slide plate 11 can be made more stable.

[0052] As Figures 4 to 6As shown, in some embodiments, a first positioning groove with an upward opening is provided in the upper part of the upper pressing member 82, and a second positioning groove with a downward opening is provided in the lower part of the lower pressing member 83. The high-speed rail slide plate 11 is positioned within the first positioning groove and the second positioning groove, and the spring groove communicates with the first positioning groove; when the lower pressing member 83 moves into contact with the upper pressing member 82, there is a spacing between the high-speed rail slide plate 11 and the bottom surface of the first positioning groove, and the spacing is a fixed value. In the initial state, the distance between the upper pressing member 82 and the lower pressing member 83 is greater than the thickness of the high-speed rail slide plate 11. Among them, protrusions are provided on the opposite sides of the upper part of the upper pressing member 82, and the first positioning groove is formed by the cooperation of the two protrusions with the upper surface of the upper pressing member 82. Protrusions are provided on the opposite sides of the lower part of the lower pressing member 83, and the second positioning groove is formed by the cooperation of the two protrusions with the lower surface of the lower pressing member 83. The opening width of the spring groove is smaller than the width of the bottom surface of the first positioning groove. With this structure, the high-speed rail slide plate 11 is limited by the first positioning groove and the second positioning groove, making the installation of the high-speed rail slide plate 11 more stable; when there is a spacing between the high-speed rail slide plate 11 and the bottom surface of the first positioning groove, it can prevent the surface of the high-speed rail slide plate 11 from being damaged after contacting the bottom surface of the groove.

[0053] In some possible implementation manners, the bearing structure 8 further includes a frame body 81, and a plurality of clamping components are provided on the frame body 81; there are a plurality of frame bodies 81, and the plurality of frame bodies 81 are arranged in sequence in the vertical direction, and the plurality of clamping components are arranged in layers in sequence in the vertical direction. Among them, the pressing device can apply pressure to the plurality of upper pressing members 82 at the uppermost part of the bearing structure 8 at the same time, so as to apply pressure to the plurality of clamping components arranged in layers in the vertical direction in sequence. With this structure, compared with the method of manually controlling the clamping tooling to clamp the high-speed rail slide plate 11 in the prior art, in this embodiment, a plurality of high-speed rail slide plates 11 can be placed simultaneously through the bearing structure 8, and when placing, it is only necessary to place the high-speed rail slide plate 11 between the lower pressing member 83 and the spring 84, which greatly improves the operation efficiency. In addition, four corner limiting blocks are further included on the upper pressing member 82 and the lower pressing member 83 at the four corner positions. By positioning with the four corner limiting blocks, the stacked bearing structure 8 can be made more stable.

[0054] As Figure 2 shown, the curing furnace in this embodiment further includes a temperature detection device for detecting the real-time temperature value of the environment around the high-speed rail slide plate 11; the control system 4 is connected to the temperature detection device for adjusting the heating temperature of the heating device 2 in real time according to the real-time temperature value. Among them, the temperature detection device can be a thermocouple 7. With this structure, the real-time temperature value of the environment around the high-speed rail slide plate 11 is detected by the temperature detection device, which is convenient for accurately controlling the temperature in the furnace and further improving the curing performance of the high-speed rail slide plate 11.

[0055] As Figure 2As shown, exemplarily, a plurality of temperature detection devices are provided, and the plurality of temperature detection devices are evenly distributed in the vertical direction. With this structure, when a plurality of high-speed rail skateboards 11 are stacked in sequence, the real-time temperature values at multiple positions in the vertical direction can be detected simultaneously by a plurality of thermocouples 7, and then the heating device 2 can be controlled to perform heating, which is convenient for ensuring the temperature uniformity in the furnace.

[0056] As Figures 1 to 4 shown, in some embodiments, the curing furnace further includes an exhaust device 5 and a blower device 6. A partition cover 10 is provided inside the furnace body 1. The high-speed rail skateboard 11 is located inside the partition cover 10. The exhaust device 5 is in communication with the inside of the partition cover 10. The blower device 6 is arranged outside the partition cover 10, and ventilation holes are provided on the partition cover 10; the air blown out by the blower device 6 flows into the inside of the partition cover 10 through the ventilation holes and is discharged through the exhaust device 5. With this structure, it is convenient to ventilate the furnace.

[0057] As Figures 1 to 4 shown, in some embodiments, a heat insulation and heat preservation cover 9 is sleeved outside the partition cover 10, and the blower device 6 is used to blow air into the space between the heat insulation and heat preservation cover 9 and the partition cover 10; the heating device 2 includes electric heating tubes located between the heat insulation and heat preservation cover 9 and the partition cover 10. The air blown out by the blower device 6 is heated by the electric heating tubes and then flows into the inside of the partition cover 10 through the ventilation holes and is discharged through the exhaust device 5. With this structure, it is convenient to heat the high-speed rail skateboard 11 by hot air and improve the heating uniformity. Among them, the heat insulation and heat preservation cover 9 is composed of heat preservation materials. Exemplarily, the furnace body 1 is composed of a frame, a 2-mm iron plate and heat preservation materials.

[0058] In an alternative manner, the exhaust device 5 includes an exhaust fan, an exhaust valve, an exhaust duct and a purification and filtration box. The exhaust fan is connected to the exhaust duct. The exhaust valve is used to control the exhaust air volume in the exhaust duct. The purification and filtration box is used to purify the air flow discharged from the exhaust duct; the control system 4 is connected to the exhaust valve and is used to control the exhaust air volume of the exhaust device 5 through the exhaust valve. Among them, the exhaust valve may include a butterfly valve and a servo motor. With this structure, the purification and filtration degree of the exhaust device 5 is improved. Exemplarily, the exhaust duct can be formed by sheet metal processing of 0.5-mm-thick snowflake iron, and the purification and filtration box can be welded by 2-mm steel plates. The inside of the purification and filtration box can use filter cotton and carbon particles as air purification fillers.

[0059] In a second aspect, the present invention also provides a curing method for an automatic pressure curing furnace, including the automatic pressure curing furnace for high-speed rail skateboards provided in the above embodiments. The curing method includes:

[0060] Clamping the high-speed rail skateboard 11 in the curing furnace;

[0061] Heating the high-speed rail skateboard 11 in the curing furnace for curing;

[0062] According to the actual clamping force received by the high-speed rail skateboard 11 during the curing process, the clamping degree of the high-speed rail skateboard 11 is adjusted in real time, so that the actual clamping force received by the high-speed rail skateboard 11 during the curing process remains stable.

[0063] In the case of adopting the above technical solution, before curing, the control system 4 can first control the pressurizing device 3 to apply pressure to the high-speed rail skateboard 11, and then control the heating device 2 to heat the high-speed rail skateboard 11 for curing through the control system 4. During the curing process, the pressure detection device can detect the real-time pressure value applied to the high-speed rail skateboard 11 by the pressurizing device 3, and then the control system 4 can control the pressurizing device 3 to apply pressure to the high-speed rail skateboard 11 according to the real-time pressure value in real time, so that during the curing process, the control system 4 can adjust the pressure applied to the high-speed rail skateboard 11 by the pressurizing device 3 in real time, thereby adjusting the clamping force received by the carbon strip and the bracket of the high-speed rail skateboard 11 in real time. Furthermore, when the adhesive of the glue layer between the carbon strip and the bracket of the high-speed rail skateboard 11 cures and shrinks during the curing process, resulting in a reduction in the overall thickness of the high-speed rail skateboard 11, the control system 4 can adjust the pressure applied to the high-speed rail skateboard 11 by the pressurizing device 3 in real time, ensuring good clamping effect between the carbon strip and the bracket of the high-speed rail skateboard 11, and further ensuring good bonding effect between the carbon strip and the bracket of the high-speed rail skateboard 11, thereby improving the curing performance of the high-speed rail skateboard 11. In addition, when the control system 4 controls the heating device 2 to heat the high-speed rail skateboard 11 and controls the pressurizing device 3 to apply pressure to the high-speed rail skateboard 11, the curing efficiency can be improved.
