Description

Technical Field

[0001] The utility model relates to the technical field of shaft workpiece processing equipment, in particular to a quenching device for shaft workpiece processing. Background Art

[0002] Shaft workpieces are common and important parts in mechanical engineering. They are usually key components that support, transmit torque or convert motion forms. The design, manufacturing and processing of shaft workpieces are crucial to the performance and stability of the entire mechanical system. The basic structure of shaft workpieces usually includes shaft segments with different diameters, keyways, threads, undercuts, center holes, etc. These structural features enable shaft workpieces to meet different working requirements, such as bearing loads, transmitting power, and installing other components.

[0003] Quenching is a metal heat treatment process, which is to heat the metal workpiece to a certain appropriate temperature and keep it for a period of time, and then immerse it in a quenching medium for rapid cooling. Common quenching media are salt water, water, mineral oil, air, etc. Through quenching, the hardness and wear resistance of metal workpieces can be improved, their comprehensive mechanical properties can be enhanced, and some steels with special properties can obtain specific physical and chemical properties, such as enhancing their ferromagnetism or improving corrosion resistance. The quenching process is mainly used for steel parts, but it is also suitable for other metal materials such as aluminum alloys, copper alloys, titanium alloys, and other metal materials, as well as solid solution treatment or heat treatment with a rapid cooling process for materials such as tempered glass.

[0004] Shaft workpiece quenching is a metal heat treatment process for shaft parts. In this process, the shaft workpiece is heated to a certain temperature and then rapidly cooled to change its internal structure, thereby improving its hardness, wear resistance and fatigue resistance. The shaft workpiece is placed in a heating device, such as a quenching furnace or an induction heater, and heated to a predetermined temperature. This temperature usually depends on the type of material and the required performance. After reaching the predetermined temperature, the workpiece will be kept in the heating device for a period of time to ensure that the internal temperature of the material is uniform and the required phase change point is reached. Subsequently, the workpiece will be quickly transferred to a cooling medium, such as oil, water or gas, for rapid cooling. The cooling rate is crucial to the quenching effect. Too fast or too slow cooling may result in poor structure or performance. After quenching, the shaft workpiece is usually tempered to eliminate the internal stress generated during the quenching process and further improve its performance. Shaft workpiece quenching is widely used, especially in the manufacture of high-precision and high-load shaft parts, such as transmission shafts, support shafts, etc. in the fields of automobiles, machine tools, aerospace, etc. After quenching, the shaft workpiece can better resist wear, deformation and fracture, thereby improving the reliability and service life of the equipment.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Combination Figure 1 and Figure 2As shown, a quenching device for processing shaft workpieces includes a mounting frame 1, on which a fixing mechanism 2, a quenching mechanism 3 and a recovery mechanism 4 are provided. The fixing mechanism 2 is used to fix the shaft workpiece to be quenched and drive the shaft workpiece to move to the quenching position, and the fixing mechanism 2 has a quenching table 5 that moves in a vertical direction; the quenching mechanism 3 is used to quench the shaft workpiece; the recovery mechanism 4 is used to recycle the wastewater generated during the quenching process; when the shaft workpiece is quenched, the fixing mechanism 2 fixes the shaft workpiece to be quenched and moves it to the quenching table 5, at which time the quenching mechanism 3 performs a quenching operation on the shaft workpiece, and the wastewater generated during the quenching process is recycled by the recovery mechanism 4. Specifically, the design of the quenching device for processing shaft workpieces is very practical and efficient. The functions of its various parts are coordinated with each other, and the quenching operation of the shaft workpiece is completed together, and environmental protection and resource recovery are emphasized. The mounting frame 1 is the basic structure of the entire quenching device, which provides a stable installation platform for the fixing mechanism 2, the quenching mechanism 3 and the recovery mechanism 4, ensuring stability and safety during the quenching process. The main responsibility of the fixing mechanism 2 is to fix the shaft workpiece to be quenched, and to drive the shaft workpiece to move to the quenching position. Among them, the quenching table 5 is an important component, which moves in the vertical direction to adapt to shaft workpieces of different sizes and ensure that the shaft workpiece can maintain a stable position during the quenching process. The quenching mechanism 3 is responsible for quenching the shaft workpiece. After the shaft workpiece is moved to the quenching position by the fixing mechanism 2, the quenching mechanism 3 will start the quenching program and quickly cool the shaft workpiece to change its internal structure and improve hardness and wear resistance. Considering that wastewater will be generated during the quenching process, the establishment of the recovery mechanism 4 is particularly necessary. It can effectively collect the wastewater generated during the quenching process and recycle it, which not only reduces environmental pollution but also saves water resources. The entire quenching process is smooth and efficient. Through the coordinated work of the fixing mechanism 2, the quenching mechanism 3 and the recovery mechanism 4, the rapid quenching of the shaft workpiece and the recycling of wastewater are achieved. This design not only improves production efficiency, but also meets the requirements of modern industry for environmental protection and resource utilization.

[0023] Combination Figure 1 and Figure 2As shown, the quenching mechanism 3 includes a Gauss ring 6 sleeved on the shaft workpiece, and the outer ring of the Gauss ring 6 is sleeved with a water spray ring 7. Specifically, the design of this quenching mechanism 3 combines the Gauss ring 6 and the water spray ring 7 to achieve accurate quenching operation on the shaft workpiece. The Gauss ring 6 is sleeved on the shaft workpiece, and its main function is to use the Gauss magnetic field for induction heating. The magnetic field generated inside the Gauss ring 6 will act on the shaft workpiece, so that it can be quickly heated to the required quenching temperature locally or as a whole. This induction heating method has the advantages of fast heating speed, high energy utilization rate, and good heating uniformity, and is very suitable for quenching the shaft workpiece. The water spray ring 7 is sleeved on the outer ring of the Gauss ring 6, and its main function is to spray water for cooling. When the shaft workpiece reaches the quenching temperature under the action of the Gauss ring 6, the water spray ring 7 will start immediately and spray water on the shaft workpiece for rapid cooling. The design of the water spray ring 7 can adjust the water spray amount and water spray angle as needed to ensure that the shaft workpiece can be evenly and fully cooled during the quenching process, thereby obtaining an ideal quenching effect. This quenching mechanism 3 combines the two methods of induction heating and water spray cooling, and can realize the precise quenching operation of the shaft workpiece. It can not only improve the quenching efficiency and quality, but also reduce energy consumption and environmental pollution, which is in line with the development trend of modern industry. It should be noted that when using this quenching mechanism 3, the close cooperation and coordination of the Gauss ring 6 and the water spray ring 7 should be ensured. At the same time, it is also necessary to adjust the parameters such as the magnetic field strength of the Gauss ring 6 and the water spray amount of the water spray ring 7 according to factors such as the material, size and quenching requirements of the shaft workpiece to obtain the best quenching effect.

[0024] Combination Figure 1 , Figure 2 and Figure 3As shown, the quenching table 5 includes a vertically arranged mounting plate 5a, and mounting seats 5b are arranged at both ends of the mounting plate 5a. A servo motor 5c is relatively arranged on the mounting seat 5b, and a fixed block 5d is arranged at the output end of the servo motor 5c. Specifically, the design of this quenching table 5 is very clever, and fully considers the stability and flexibility requirements of the shaft workpiece during the quenching process. The mounting plate 5a is the main structure of the quenching table 5, which is arranged vertically and provides a stable installation foundation for other components. Mounting seats 5b are arranged at both ends of the mounting plate 5a. Such a design makes the entire quenching table 5 structure more stable and can withstand greater weight and impact. A servo motor 5c is relatively arranged on the mounting seat 5b, which is a key component for realizing the vertical movement of the quenching table 5. The servo motor 5c has the characteristics of high precision, high speed and high reliability, and can realize accurate control of the position of the shaft workpiece. Driven by the servo motor 5c, the fixed block 5d can move up and down, thereby driving the shaft workpiece installed on the fixed block 5d to move to the quenching position. The fixed block 5d is an important component for fixing the shaft workpiece. It can be adjusted according to the size and shape of the shaft workpiece to ensure that the shaft workpiece can maintain a stable position during the quenching process. At the same time, the fixed block 5d is connected to the output end of the servo motor 5c, so that the shaft workpiece can move with the drive of the servo motor 5c. The design of this quenching table 5 makes the movement of the shaft workpiece during the quenching process more flexible and precise. By adjusting the parameters of the servo motor 5c, the position of the shaft workpiece can be adjusted quickly and accurately, improving the efficiency and quality of the quenching operation. At the same time, the stability of the quenching table 5 is also effectively guaranteed, providing reliable support for the quenching of the shaft workpiece. In summary, the design of this quenching table 5 fully considers the actual needs of shaft workpiece quenching, has the advantages of simple structure, easy operation, good stability, etc., and is an indispensable and important equipment in shaft workpiece processing.

[0025] Combination Figure 1 , Figure 2 and Figure 3As shown, a sliding block 5b1 is provided on the back of the mounting plate 5a, and a groove 1a is provided on the mounting frame 1, and the groove 1a is slidably connected to the sliding block 5b1. Specifically, in the design of the quenching table 5, the sliding block 5b1 on the back of the mounting plate 5a is slidably connected to the groove 1a on the mounting frame 1. This detail design further enhances the stability and reliability of the quenching table 5. The setting of the sliding block 5b1 enables the quenching table 5 to move vertically and smoothly on the mounting frame 1. When the servo motor 5c drives the fixed block 5d to move up and down, the mounting plate 5a and the sliding block 5b1 on the back thereof will slide along the groove 1a. This sliding connection method not only ensures the smoothness of the movement of the quenching table 5, but also limits its moving direction, preventing the quenching table 5 from deflecting or shaking during the movement. The design of the groove 1a provides a track for the sliding block 5b1 to move, ensuring that the sliding block 5b1 can move along a predetermined path. The depth and width of the groove 1a are precisely calculated to ensure that the sliding block 5b1 can be tightly embedded therein to achieve a stable sliding connection. This sliding connection method also makes the installation and removal of the quenching table 5 more convenient. When the quenching table 5 needs to be replaced or repaired, the quenching table 5 can be easily removed from the mounting frame 1 by simply removing the sliding block 5b1 from the groove 1a. In summary, the sliding connection design between the sliding block 5b1 and the groove 1a not only improves the stability of the quenching table 5, but also facilitates its installation and removal. This design reflects the precise control of details and the high attention to practicality, which helps to improve the efficiency and quality of quenching operations.

[0026] Combination Figure 1 , Figure 2 and Figure 3As shown, the mounting frame 1 is provided with an electric cylinder 1b, and the output end of the electric cylinder 1b is fixedly connected to the sliding block 5b1. Specifically, the electric cylinder 1b is provided on the mounting frame 1, and the output end of the electric cylinder 1b is fixedly connected to the sliding block 5b1. This design further improves the moving efficiency and precision of the quenching table 5. As an efficient and precise driving device, the electric cylinder 1b can provide a stable and powerful driving force for the sliding block 5b1. When the electric cylinder 1b is started, its output end will push the sliding block 5b1 to move along the groove 1a, thereby driving the entire quenching table 5 to move up and down. Compared with the traditional driving method, the electric cylinder 1b has a higher response speed and more accurate positioning ability, which can realize the rapid and precise adjustment of the position of the quenching table 5. In addition, the driving force of the electric cylinder 1b can be accurately adjusted by the control system to adapt to shaft workpieces of different sizes and weights. This flexibility enables the quenching device to cope with more types of shaft workpiece quenching requirements, improving the versatility and practicality of the equipment. At the same time, the fixed connection method between the electric cylinder 1b and the sliding block 5b1 also ensures the stability and reliability between the two. This connection method can effectively prevent displacement or falling off due to vibration or impact during the quenching process, ensuring the stability and safety of the quenching operation. In summary, the fixed connection design of the electric cylinder 1b and the sliding block 5b1 not only improves the movement efficiency and accuracy of the quenching table 5, but also enhances the stability and reliability of the equipment. This design makes the quenching device more efficient, accurate and safe, and helps to improve the quality and efficiency of the quenching of the shaft workpiece.

[0027] Combination Figure 1 , Figure 2 and Figure 3As shown, the recovery mechanism 4 includes a recovery tank 4a arranged at the bottom of the mounting frame 1, a water pump is arranged in the recovery tank 4a, and the output end of the water pump is fixedly connected to the water spray ring 7. Specifically, the design of the recovery mechanism 4 cleverly combines the recovery tank 4a and the water pump, realizing the effective recovery and reuse of the wastewater generated during the quenching process. The recovery tank 4a is arranged at the bottom of the mounting frame 1, below the quenching operation, so that the wastewater generated during the quenching process can be smoothly flowed into the recovery tank 4a. The recovery tank 4a has a certain volume and can accommodate a certain amount of wastewater, thereby ensuring that the wastewater will not overflow or flow around when the quenching operation is carried out. The water pump arranged in the recovery tank 4a is the core component of the recovery mechanism 4. The water pump extracts the wastewater in the recovery tank 4a through its powerful pumping capacity, and transports the wastewater to the water spray ring 7 through its output end. This design allows the wastewater to be recycled, which not only saves water resources, but also reduces production costs. The water spray ring 7 is fixedly connected to the output end of the water pump to ensure that the wastewater can flow into the water spray ring 7 stably and continuously. During the quenching process, the water spray ring 7 uses the recycled waste water to cool the shaft workpiece. Since the waste water may contain some impurities or heat generated during the quenching process, this will also affect the cooling effect to a certain extent. However, by reasonably designing the structure and water spraying method of the water spray ring 7, this effect can be effectively reduced to ensure the quenching quality. In addition, in order to ensure the quality and reuse effect of the recycled waste water, it is also possible to consider setting a filtering device in the recovery tank 4a to perform preliminary filtering on the waste water and remove large particles of impurities therein. At the same time, regular cleaning and maintenance of the recovery tank 4a and the water pump are also important measures to ensure the normal operation of the waste water recovery system. In summary, the recovery mechanism 4 realizes the effective recovery and reuse of quenching waste water through the combined design of the recovery tank 4a and the water pump, which not only saves resources but also reduces costs, and meets the requirements of modern industry for environmental protection and sustainable development.

[0028] Combination Figure 1 , Figure 2 and Figure 3As shown, a filter screen 4b is provided inside the recovery tank 4a. Specifically, it is a very practical and necessary improvement measure to provide a filter screen 4b inside the recovery tank 4a. The existence of the filter screen 4b can effectively filter out impurities and particulate matter in the wastewater, ensure the cleanliness of the recycled water, and then ensure the cooling effect when it is reused. Specifically, when the wastewater generated during the quenching process flows into the recovery tank 4a, the filter screen 4b will quickly intercept and retain large particles of impurities in the wastewater, such as metal debris, oxides, etc. If these impurities are pumped in by the water pump and transported to the water spray ring 7, they may block the water spray hole, affecting the water spray effect and quenching quality. Through the filtering effect of the filter screen 4b, the purity of the recycled water can be ensured, thereby ensuring the normal operation of the water spray ring 7 and the smooth progress of the quenching operation. In addition, the design of the filter screen 4b also needs to take into account the factors of easy cleaning and replacement. Since impurities in the wastewater may gradually accumulate on the filter screen 4b, resulting in a decrease in the filtering effect, the filter screen 4b needs to be cleaned regularly. At the same time, when the filter screen 4b is damaged or the filtering effect cannot meet the requirements, a new filter screen 4b should be replaced in time to ensure the continuous and effective operation of the wastewater recovery system. In summary, the arrangement of the filter screen 4b inside the recovery tank 4a is an important measure to ensure the effect of wastewater recovery and reuse. It can not only improve the cleanliness of the recovered water and ensure the smooth progress of the quenching operation, but also extend the service life of equipment such as the water spray ring and reduce maintenance costs.

[0029] Combination Figure 1 and Figure 2As shown, the mounting frame 1 is provided with a control system. Specifically, in the quenching device, the control system provided on the mounting frame 1 is the core of the entire device, which is responsible for coordinating and managing the work of each part to ensure the smooth progress of the quenching process. The control system usually includes two parts: hardware and software. The hardware part may include circuit boards, sensors, actuators, etc., which are responsible for receiving and sending signals and executing control commands. The software part is responsible for processing these signals and accurately controlling and adjusting each part according to preset programs and parameters. Through driving devices such as servo motors 5c and electric cylinders 1b, the control system can accurately control the up and down movement of the quenching table 5 to ensure that the shaft workpiece can be accurately moved to the quenching position. The control system can set parameters such as quenching time and temperature, and implement quenching operations on the shaft workpiece through devices such as Gaussian rings 6 and water spray rings 7. During the quenching process, the control system can also monitor the quenching state in real time to ensure that the quenching effect meets the requirements. By controlling the switch and flow of the water pump, the control system can realize the effective recovery and reuse of wastewater. At the same time, the control system can also monitor the state of wastewater in the recovery tank 4a, and promptly remind the operator to clean and replace it. The control system also has fault monitoring and alarm functions, which can detect and handle equipment failures in a timely manner to ensure the continuity and stability of the quenching process. In short, the setting of the control system makes the operation of the quenching device easier, more accurate and more reliable, and improves the quality and efficiency of quenching. At the same time, by continuously optimizing and upgrading the control system, the performance and function of the equipment can be further improved to meet higher production needs.
