Description

Technical Field

[0001] This utility model relates to the field of wind turbine gear processing technology, and in particular to a carburizing and quenching device for wind turbine gear processing. Background Technology

[0002] The carburizing and quenching equipment for wind turbine gear processing is a precision device specifically designed for the heat treatment of gears in large wind turbines. It is mainly used to improve the hardness, wear resistance and fatigue strength of gear tooth surfaces through carburizing and subsequent quenching processes, thereby meeting the requirements for long-term stable operation of wind turbine gears under harsh working conditions.

[0003] The loading and unloading of workpieces, opening and closing of the housing, and temperature monitoring and adjustment in traditional carburizing and quenching equipment for wind turbine gear processing often require a large amount of manual intervention. Manual operation is not only slow, but also prone to errors or inconsistent processing times due to fatigue and negligence, resulting in low overall efficiency. In addition, traditional carburizing and quenching equipment for wind turbine gear processing usually lacks a coolant circulation system, and the cooled coolant is directly discharged, resulting in a huge waste of water resources. The waste coolant may contain oil, impurities, etc., and direct discharge will also cause environmental pollution.

[0004] Therefore, those skilled in the art have provided a carburizing and quenching apparatus for wind turbine gear processing to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a carburizing and quenching device for wind turbine gear processing. The automated design reduces manual operation, improving efficiency and safety. Furthermore, a water tank stores coolant, and a high-pressure pump pressurizes the coolant before spraying it onto the workpiece inside the quenching chamber, achieving rapid and uniform cooling. After use, the coolant flows back to the water tank through a drain pipe and is filtered as it passes through a filter plate, ensuring the recycled coolant remains relatively clean, maintaining the efficiency of the cooling system, and realizing water recycling.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A carburizing and quenching device for wind turbine gear processing includes a base plate, a carburizing box, and a quenching box. A protective shell is fixedly connected to the center of the surface of the base plate. A servo motor is fixedly connected to the inner bottom surface of the protective shell. The output end of the servo motor passes through the protective shell to the upper end of the protective shell and is fixedly connected to a support frame. An electric telescopic rod is fixedly connected to the lower surface of one side of the upper end of the support frame. A sealing cover is fixedly connected to the output end of the electric telescopic rod. A placement rack is fixedly connected to the lower surface of the sealing cover. A certain feature is provided on the lower end of one side of the base plate. A water tank has a filter plate fixedly connected to its upper inner wall, and a high-pressure pump fixedly connected to its outer wall on one side. The suction port of the high-pressure pump is connected to the inside of the water tank through a pipe, and the outlet of the high-pressure pump is connected to a connecting pipe. Both sides of the upper end of the connecting pipe penetrate the quenching box to both sides of the inside of the quenching box and are fixedly connected to multiple nozzles. A drain pipe is connected to the other side of the bottom surface of the quenching box. The lower end of the drain pipe penetrates the bottom plate to the upper end of the inside of the water tank, and the drain pipe is located above the filter plate.

[0008] Through the above technical solution, the direction is controlled by a servo motor, the support frame serves as a connector, and the electric telescopic rod is responsible for controlling the lifting stroke and speed. This allows the loading and unloading of workpieces, as well as the opening and closing of the box's sealing cover, to be completed automatically and precisely, reducing manual operation and improving efficiency and safety. The coolant is stored in a water tank, and the high-pressure pump pressurizes the coolant and sprays it onto the workpieces inside the quenching box through nozzles, achieving rapid and uniform cooling. After use, the coolant flows back to the water tank through a drain pipe and is filtered as it flows through a filter plate, ensuring that the recycled coolant is relatively clean, maintaining the efficiency of the cooling system, and realizing the recycling of water.

[0009] Furthermore, the lower end of the quenching box is fixedly connected to one side of the upper surface of the base plate, the lower end of the carburizing box is fixedly connected to the other side of the upper surface of the base plate, a heating wire is fixedly connected to the middle of the bottom surface of the carburizing box, and a heater, a temperature controller and a temperature sensor are fixedly connected to the outer wall of the front end of the carburizing box from one side to the other. The rear end of the temperature sensor penetrates through the carburizing box into the interior of the carburizing box.

[0010] The above technical solution achieves physical separation by fixing the carburizing chamber and the quenching chamber to both sides of the base plate. This helps prevent the carburizing atmosphere from interfering with the quenching process and facilitates separate operation and maintenance of the two chambers. A closed-loop temperature control system is formed by heating wires, heaters, temperature controllers, and temperature sensors. This system can accurately heat the carburizing medium and maintain it within the temperature range required by the process, ensuring the consistency and quality of the carburizing process. The temperature sensors provide real-time temperature data to the temperature controller, ensuring the timeliness and accuracy of the control.

[0011] Furthermore, positioning holes are provided at the four corners of the upper surface of the carburizing box and the quenching box, and positioning rods are fixedly connected at the four corners of the lower surface of the sealing cover. The outer wall of the positioning rod is tightly fitted with the inner wall of the positioning hole, and the lower surface of the sealing cover is tightly fitted with the upper surface of the carburizing box and the quenching box respectively.

[0012] The above technical solution provides a preliminary positioning seal through the tightly fitting positioning rod and positioning hole, ensuring that the lower surface of the sealing cover can be pressed evenly and stably against the upper surface of the box, minimizing the gap between the sealing surfaces, and thus effectively preventing leakage of quenching liquid, carburizing atmosphere or other processing media in high temperature, high pressure or vacuum environments.

[0013] Furthermore, a PLC control panel is fixedly connected to the outer wall of the front end of the base plate, and anti-slip support legs are fixedly connected to the four corners of the lower surface of the base plate.

[0014] The above technical solution uses a PLC control panel to control the operation of the entire equipment, and anti-slip support legs to support the entire equipment, increase stability, and prevent slippage.

[0015] Furthermore, the quenching box is located at the lower end of the placement rack;

[0016] Through the above technical solution, this design allows the workpiece on the rack to be sent into the quenching box for quenching treatment during the operation process. Since the two are aligned, the workpiece can fall directly into the quenching box without additional alignment operations.

[0017] Furthermore, the upper surface of the water tank is in close contact with the lower surface of the base plate;

[0018] The above technical solution effectively prevents dust, moisture, or other small particles from entering the water tank through the gap between the base plate and the water tank by ensuring a tight fit, thus maintaining a clean internal environment.

[0019] Furthermore, a fixing plate is fixedly connected to the upper end of the connecting pipe on the side away from the middle of the quenching box, and the fixing plate on the side away from the middle of the quenching box is fixedly connected to both sides of the inner wall of the quenching box.

[0020] The above technical solution provides a stable support point for the connecting pipe through the fixing plate, so that the connecting pipe is fixed in the box, thereby improving its vibration resistance and displacement resistance.

[0021] Furthermore, an inclined plate is fixedly connected to the inner wall at the lower end of the quenching box;

[0022] The above technical solution uses an inclined plate to allow liquids and residues generated during the quenching process to flow naturally to the lowest point of the inclined plate by gravity, thereby discharging waste liquid or impurities and keeping the bottom of the box clean.

[0023] This utility model has the following beneficial effects:

[0024] This utility model proposes a carburizing and quenching device for wind turbine gear processing. Through automated design, it reduces manual operation, improves efficiency and safety, and provides coolant storage through a water tank. A high-pressure pump pressurizes the coolant and sprays it onto the workpiece in the quenching chamber through nozzles, achieving rapid and uniform cooling. After use, the coolant flows back to the water tank through a drain pipe and is filtered as it flows through a filter plate, ensuring that the recycled coolant is relatively clean, maintaining the efficiency of the cooling system, and realizing water recycling.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 , Figure 2 and Figure 5This utility model provides a specific embodiment: a carburizing and quenching device for wind turbine gear processing, including a base plate 1, a carburizing box 2, and a quenching box 3. A protective shell 103 is fixedly connected to the middle of the surface of the base plate 1. A servo motor 5 is fixedly connected to the inner bottom surface of the protective shell 103. The output end of the servo motor 5 passes through the protective shell 103 to the upper end of the protective shell 103 and is fixedly connected to a support frame 501. An electric telescopic rod 502 is fixedly connected to the lower surface of one side of the upper end of the support frame 501. A sealing cover 503 is fixedly connected to the output end of the telescopic rod 502. A placement rack 505 is fixedly connected to the lower surface of the sealing cover 503. A water tank 4 is installed at the lower end of one side of the base plate 1. A filter plate 401 is fixedly connected to the inner wall of the upper end of the water tank 4. A high-pressure pump 6 is fixedly connected to the outer wall of one side of the water tank 4. The suction port of the high-pressure pump 6 is connected to the inside of the water tank 4 through a pipe. The outlet of the high-pressure pump 6 is connected to a connecting pipe 601. Both sides of the upper end of the connecting pipe 601 penetrate the quenching box 3. Multiple nozzles 602 are fixedly connected to both sides inside the quenching chamber 3. A drain pipe 302 is connected through the bottom surface of the quenching chamber 3 to the other side. The lower end of the drain pipe 302 passes through the bottom plate 1 to the upper end inside the water tank 4. The drain pipe 302 is located above the filter plate 401. The direction is controlled by the servo motor 5. The support frame 501 serves as a connector. The electric telescopic rod 502 is responsible for controlling the lifting stroke and speed, so that the loading and unloading of workpieces and the opening and closing of the chamber sealing cover 503 can be completed automatically and accurately, reducing manual operation and improving efficiency and safety. The water tank 4 provides storage for coolant. The high-pressure pump 6 pressurizes the coolant and sprays it onto the workpieces inside the quenching chamber 3 through the nozzles 602, which can achieve rapid and uniform cooling. After the coolant is used, it flows back to the water tank 4 through the drain pipe 302 and is filtered when it flows through the filter plate 401, ensuring that the recycled coolant is relatively clean, maintaining the efficiency of the cooling system, and realizing the recycling of water.

[0035] Reference Figure 3 and Figure 6The lower end of the quenching chamber 3 is fixedly connected to one side of the upper surface of the base plate 1, and the lower end of the carburizing chamber 2 is fixedly connected to the other side of the upper surface of the base plate 1. A heating wire 202 is fixedly connected to the middle of the bottom surface of the carburizing chamber 2. A heater 203, a temperature controller 204, and a temperature sensor 205 are fixedly connected from one side to the other on the outer wall of the front end of the carburizing chamber 2. The rear end of the temperature sensor 205 penetrates through the carburizing chamber 2 into its interior. By fixing the carburizing chamber 2 and the quenching chamber 3 to the two sides of the base plate 1 respectively, physical separation is achieved, which helps to prevent the carburizing atmosphere from interfering with the quenching process and also facilitates the operation and maintenance of the two chambers separately. The heating wire 202, heater 203, temperature controller 204, and temperature sensor 205 together constitute a closed-loop temperature control system, which can accurately heat the carburizing medium and maintain it within the temperature range required by the process. To ensure the consistency and quality of the carburizing process, the temperature sensor 205 provides real-time temperature data to the temperature controller 204, ensuring timely and accurate control. Positioning holes 201 are provided at the four corners of the upper surface of the carburizing chamber 2 and the quenching chamber 3. Positioning rods 504 are fixedly connected to the four corners of the lower surface of the sealing cover 503. The outer walls of the positioning rods 504 are tightly fitted to the inner walls of the positioning holes 201. The lower surface of the sealing cover 503 is tightly fitted to the upper surfaces of the carburizing chamber 2 and the quenching chamber 3. The tightly fitted positioning rods 504 and the positioning holes 201 themselves provide a preliminary positioning seal, ensuring that the lower surface of the sealing cover 503 can be evenly and stably pressed against the upper surface of the chamber, minimizing the gap between the sealing surfaces and effectively preventing leakage of quenching liquid, carburizing atmosphere, or other processing media under high temperature, high pressure, or vacuum conditions.

[0036] Reference Figure 2 , Figure 3 and Figure 4A PLC control panel 102 is fixedly connected to the outer wall of the front end of the base plate 1. Anti-slip support legs 101 are fixedly connected to the four corners of the lower surface of the base plate 1. The PLC control panel 102 is used to control the operation of the entire equipment, and the anti-slip support legs 101 are used to support the entire equipment and increase stability to prevent slippage. The quenching box 3 is located directly below the placement rack 505. This design allows the workpiece to fall directly into the quenching box 3 for quenching treatment when it needs to be placed on the placement rack 505, as the two are aligned. No additional alignment operation is required. The upper surface of the water tank 4 is in close contact with the lower surface of the base plate 1. This close contact effectively prevents dust, moisture, or other small particles from entering the base plate. The gap between 1 and water tank 4 allows water tank 4 to enter the interior of water tank 4, keeping the interior environment of water tank 4 clean. The upper end of connecting pipe 601 is fixedly connected to the side away from the middle of quenching box 3 with fixing plate 603. The side of fixing plate 603 away from the middle of quenching box 3 is fixedly connected to both sides of the inner wall of quenching box 3. The fixing plate 603 provides a stable support point for connecting pipe 601, so that connecting pipe 601 is fixed in the box, improving its vibration resistance and displacement resistance. The lower end of the inner wall of quenching box 3 is fixedly connected to inclined plate 301. The inclined plate 301 is used to allow liquids and residues generated during quenching to flow naturally to the lowest point of the inclined plate 301 by gravity, thereby discharging waste liquid or impurities and keeping the bottom of the box clean.

[0037] Working Principle: First, the operator starts the equipment via the PLC control panel 102. The servo motor 5 drives the support frame 501, and the electric telescopic rod 502 raises the sealing cover 503 and the placement rack 505 below it, placing the gear to be processed on the placement rack 505. Then, the electric telescopic rod 502 extends, lowering the placement rack 505 along with the gear into the carburizing chamber 2 located directly below it. The sealing cover 503 then descends, precisely aligning with the positioning hole 201 on the upper surface of the carburizing chamber 2 via the positioning rod 504 on its lower surface and inserting it to ensure a tight seal between the cover and the chamber. At this time, the heating wire 202 and the heater 203 begin to work, and the temperature sensor 205 feeds back the real-time temperature to the temperature controller 204 to control the temperature of the carburizing medium. Once the set temperature is reached, the gear is carburized. After carburizing, the electric telescopic rod 502 retracts, removing the sealing cover 503, the placement rack 505, and the gear. Then, the servo motor 5 starts again, causing the support frame 501 to rotate 180°, and the gear is transferred to the top of the quenching box 3 on one side. At this time, the electric telescopic rod 502 extends again, lowering the placement rack 505 along with the gear into the quenching box 3 located directly below it. During the entire quenching process, the water tank 4 below the base plate 1 pressurizes the coolant through the high-pressure pump 6, and sprays it onto the gear surface inside the quenching box 3 through the connecting pipe 601 and the nozzle 602. The used liquid flows back to the water tank 4 through the drain pipe 302, is filtered by the filter plate 401, and is recycled. All parts of the equipment are centrally controlled through the PLC control panel 102, and the anti-slip support leg 101 ensures stable operation of the equipment.
