[0017] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0018] The following describes in detail, with reference to the accompanying drawings, a high-frequency induction hardening device for curved surfaces of pressure rollers according to an embodiment of the present invention.

[0019] Example 1 For easier understanding, please refer to Figures 1 to 4 An embodiment of a high-frequency induction hardening device for curved surfaces of pressure rollers provided by this utility model includes a housing 1 and an induction heater 4. One end of the housing 1 is provided with a conveying hole 3 that penetrates the housing 1, and a continuous processing mechanism is provided inside the housing 1. The continuous processing mechanism includes a conveyor roller 7, a water tank 14, a hollow plate 15, a nozzle 16, and a water pump 18. The conveyor roller 7 is rotatably connected inside the housing 1 and is located on one side inside the housing 1. The water tank 14 is fixedly installed on the other side inside the housing 1. The hollow plate 15 is fixedly installed on the side wall of the water tank 14. The nozzle 16 is installed inside the hollow plate 15. The water pump 18 is installed inside the water tank 14. The output end of the water pump 18 is connected to the nozzle 16 inside the hollow plate 15. A drain hole 19 is opened on one side of the housing 1. An induction heater 4 is fixedly installed inside the housing 1. The heating section of the induction heater 4 is located between the conveyor roller 7 and the water tank 14.

[0020] It should be noted that the conveying hole 3 provides a channel for the pressure roller to enter and exit. The conveying roller 7 can drive the pressure roller to move within the housing 1, so that the pressure roller passes through the heating section of the induction heater 4 and the cooling area of ​​the hollow plate 15 in sequence, realizing continuous quenching and cooling. The induction heater 4 can perform high-frequency induction heating on the curved surface of the pressure roller to complete the quenching. The cooling structure composed of the water storage tank 14, water pump 18, hollow plate 15 and nozzle 16 can cool the pressure roller in time after quenching. The drain hole 19 can drain the used cooling water to ensure the continuous operation of the device.

[0021] In some embodiments, such as Figure 4As shown, a protective frame 17 is fixedly installed inside the water storage tank 14, and a water pump 18 is fixedly installed inside the protective frame 17. The input end of the water pump 18 is connected to the water storage tank 14. A filling pipe 5 is fixedly installed on the top of the water storage tank 14. Several nozzles 16 are provided, and the several nozzles 16 are evenly distributed inside the hollow plate 15. The hollow plate 15 is an arc-shaped plate.

[0022] It should be noted that the protective frame 17 can protect the water pump 18, preventing it from being damaged by collisions or other factors during operation and ensuring its stable operation. The filling pipe 5 facilitates the replenishment of cooling water into the water storage tank 14, avoiding the impact of insufficient water on the cooling effect. Multiple evenly distributed nozzles 16 can spray cooling water more evenly on the curved surface of the pressure roller, improving the uniformity of cooling. The arc-shaped hollow plate 15 is adapted to the shape of the curved surface of the pressure roller, allowing the cooling water sprayed from the nozzles 16 to act more closely on the surface of the pressure roller, further improving the cooling effect.

[0023] In some embodiments, such as Figure 1 As shown, a servo motor 6 is fixedly installed on one side of the housing 1, a conveying roller 7 is fixedly installed at the output end of the servo motor 6, and a protective pad 8 is fixedly installed on the side wall of the conveying roller 7.

[0024] It should be noted that the servo motor 6 provides power for the rotation of the conveyor roller 7, and its speed can be precisely controlled, thereby accurately adjusting the conveying speed of the pressure roller to adapt to different quenching process requirements. The protective pad 8 is made of elastic material, which can avoid rigid contact between the conveyor roller 7 and the pressure roller, prevent the surface of the pressure roller from being scratched, and play a role in protecting the pressure roller.

[0025] Example 2 In some embodiments, such as Figure 2 As shown, an installation column 9 is fixedly installed between the induction heater 4 and the water storage tank 14. A spring 10 is fixedly installed inside the installation column 9. A movable column 11 is fixedly installed on the top of the spring 10. The movable column 11 is slidably connected to the inside of the installation column 9 through the spring 10. An installation plate 12 is fixedly installed on the top of the movable column 11. Several sensors 13 are fixedly installed inside the installation plate 12. A display and control integrated machine 2 is fixedly installed on one side of the housing 1.

[0026] It should be noted that sensor 13 is a contact temperature sensor. Sensor 13 can monitor parameters such as the temperature of the pressure roller after heating in real time and transmit the monitoring data to the display and control all-in-one machine 2. Based on this data, the display and control all-in-one machine 2 can adjust the heating power of the induction heater 4, the speed of the servo motor 6, and the water supply of the water pump 18, making the quenching process more precise and controllable. The cooperation between spring 10 and movable column 11 gives the mounting plate 12 a certain lifting space, which can adapt to pressure rollers of different diameters and ensure that sensor 13 can always maintain a suitable monitoring distance in contact with the surface of the pressure roller.

[0027] In this utility model, the induction heater 4, servo motor 6, water pump 18, sensor 13 and display and control integrated machine 2 are known components, and will not be described in detail here.

[0028] Working principle: In use, an appropriate amount of cooling water is first added to the water storage tank 14 through the filling pipe 5. The pressure roller to be quenched is placed on the conveying roller 7 through the conveying hole 3. The servo motor 6 is started, and the servo motor 6 drives the conveying roller 7 to rotate, thereby conveying the pressure roller into the housing 1. When the pressure roller passes through the heating section of the induction heater 4, the induction heater 4 works to perform high-frequency induction heating on the curved surface of the pressure roller. The heated pressure roller is then conveyed to the sensor 13. The sensor 13 monitors the temperature and other parameters of the pressure roller and transmits the data to the display and control all-in-one machine 2. Subsequently, the pressure roller is conveyed to the hollow plate 15. The display and control all-in-one machine 2 controls the water pump 18 to work according to the monitoring data of the sensor 13. The water pump 18 conveys the cooling water in the water storage tank 14 to the hollow plate 15, and then sprays it onto the curved surface of the pressure roller through the nozzle 16 to cool the pressure roller, thereby completing the quenching. The wastewater generated during the cooling process is discharged through the drain hole 19. The processed pressure roller is finally conveyed out of the housing 1. The whole process realizes the continuous and automated processing of the curved surface quenching of the pressure roller.

[0029] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
