[0017] Compared with the prior art, the high-strength gear box with built-in reinforcing ribs of the alloy ball processing quenching device for aircraft blade surface shot blasting has the following beneficial effects:

[0018] 1、In the quenching process, uniform heating is the key factor to ensure the quality of alloy pellets. In the device, the rotation of the base plate drives the storage frame and the alloy pellets to rotate synchronously, so that the alloy pellets can uniformly receive heat radiation from the heating wires on the inner wall of the quenching furnace in all directions. The local overheating or overcooling phenomenon caused by static placement is avoided, the consistency of the overall temperature of the alloy pellets is ensured, and the formation of uniform austenite organization is helpful to lay a foundation for obtaining good quenching performance.

[0019] Since the alloy pellets are uniformly heated during rotation, the quenching conditions experienced by each alloy pellet are basically the same. This makes a batch of alloy pellets have high consistency in key performance indicators such as hardness, strength, toughness, etc. For alloy pellets used for shot peening on the surface of aircraft blades, such consistency of performance is crucial to ensure the stability and reliability of the surface quality of the aircraft blades after shot peening treatment, and to improve the service life and performance of the aircraft blades.

[0020] And during the heating process, the rotation of the alloy pellets promotes the full diffusion of the internal atoms. The continuous rotation of the base plate drives the alloy pellets, so that the atoms in different parts of the alloy pellets have more opportunities to be uniformly distributed, thereby accelerating the organization homogenization process. Uniform organization is conducive to the phase transition of different parts of the alloy pellets in the expected way during quenching cooling, so as to obtain ideal microstructure and further improve the comprehensive performance of the alloy pellets.

[0021] 2、The rotation speed of the base plate can be adjusted according to the material, size of the alloy pellets and specific quenching process requirements. The operator can accurately adjust the heating time and heating degree of the alloy pellets by controlling the rotation speed, so as to realize fine control of the quenching process. This controllability makes the device adapt to the quenching needs of different types of alloy pellets, improves the versatility and flexibility of the device, and meets the diversified production requirements.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] The utility model provides a kind of alloy ball processing quenching device for aircraft blade surface shot blasting as shown in Figures 1-4 The utility model provides a kind of alloy ball processing quenching device for aircraft blade surface shot blasting as shown in

[0029] The left side of quenching furnace main body 1 upper and lower end positions are respectively provided with motor bracket, and the upper side position of motor bracket is provided with hydraulic pump drive motor 3, and the lower side position of motor bracket is provided with oil pump 4;

[0030] The rear side of motor bracket upper and lower end positions is respectively provided with fixed frame 5, and the left side middle position of fixed frame 5 is provided with hydraulic sleeve rod 6, and the upper side position of hydraulic sleeve rod 6 is provided with hydraulic rod 7, and the connecting position of hydraulic rod 7 and cover 2 is provided with connecting frame 8;

[0031] The upper side position of connecting frame 8 is provided with rotating motor 9, and the output shaft of rotating motor 9 and the lower side connecting position of cover 2 are provided with rotating disc 12, and the middle inner side position of rotating disc 12 is provided with connecting hole 13;

[0032] The middle inner side bottom position of quenching furnace main body 1 is provided with chassis 15, and the upper side middle position of chassis 15 is provided with rotating rod 11, and the left and right side positions of rotating rod 11 are respectively provided with slot 14;

[0033] Hydraulic pump drive motor 3 and rotating motor 9 are respectively powered by connecting external power supply.

[0034] Hydraulic sleeve rod 6 and oil pump 4 are connected by pipeline, and oil pump 4 and hydraulic pump drive motor 3 are drivingly connected.

[0035] Hydraulic rod 7 can move up and down in hydraulic sleeve rod 6, and the inner wall of quenching furnace main body 1 is provided with heating wire.

[0036] Optionally, the operator can place the alloy pellets to be quenched on the external storage rack, and connect and fix the storage rack to the base plate 15 by bolt connection when quenching is performed.

[0037] In this embodiment, quenching is a heat treatment process that changes the microstructure of a metal material by heating, holding and rapid cooling, thereby obtaining the desired performance. For alloy pellets, they are mainly made of alloy materials composed of multiple metal elements. During quenching, the alloy pellets are first heated to a specific temperature, so that the atoms in the alloy pellets have enough energy, and the crystal lattice structure changes. When a certain temperature is reached (different due to different alloy compositions), the microstructure of the alloy pellets is transformed into austenite, which is called austenitizing. Austenite has good plasticity and low strength. In the austenitic state, keep for a period of time to allow the microstructure of the alloy pellets to be fully homogenized, and prepare for subsequent quenching and cooling. Then, the alloy pellets are rapidly cooled. Due to the extremely fast cooling speed, the austenite cannot be transformed into other more stable microstructures, but is transformed into martensite. Martensite has high hardness and high strength, thereby improving the hardness and wear resistance of the alloy pellets.

[0038] When using the device, the operator can place the alloy pellets on the storage rack, which can be connected and fixed to the base plate 15 inside the quenching furnace body 1 by bolt connection or other suitable connection methods. Ensure that all equipment connections are normal, and that the hydraulic pump drive motor 3 and the rotating motor 9 have been connected to an external power source.

[0039] Start the hydraulic pump drive motor 3, and the motor 3 drives the oil pump 4 to work. The oil pump 4 delivers oil to the hydraulic sleeve rod 6, and the oil pressure pushes the hydraulic rod 7 to move upward in the hydraulic sleeve rod 6. Since the upper end of the hydraulic rod 7 is welded to the connecting frame 8, and the connecting frame 8 is connected to the cover 2 by bolts, the upward movement of the hydraulic rod 7 drives the connecting frame 8 and the cover 2 to move upward together, thereby opening the furnace opening of the quenching furnace body 1.

[0040] After the cover 2 is opened, the storage rack with the alloy pellets is connected and fixed to the base plate 15 by the established connection method. After placing, start the hydraulic pump drive motor 3 again, and operate in reverse to make the hydraulic rod 7 move downward in the hydraulic sleeve rod 6, drive the cover 2 to descend, until the cover 2 closes the quenching furnace body 1, and the heating metal wire is turned on to heat.

[0041] Once the alloy shot reaches the specified quenching temperature and is held at that temperature for a sufficient period, the heating wire is turned off, and heating is stopped. By opening the cover 2, the alloy shot is rapidly exposed to air or placed in a specific cooling medium (such as oil or water) for rapid cooling, promoting the transformation of austenite into martensite and completing the quenching process. After quenching, the hydraulic pump drive motor 3 is restarted to raise the hydraulic rod 7 and open the cover 2. Subsequently, the quenched alloy shot, along with the storage rack, is removed from the chassis 15, completing the entire alloy shot processing and quenching process.

[0042] like Figures 1-4 As shown, the rotating motor 9 is connected to the connecting frame 8 by bolts. A fixing rod 10 is provided at the connection position between the output shaft of the rotating motor 9 and the rotating disk 12. The fixing rod 10 is connected to the connecting frame 8 and the output shaft of the rotating motor 9 by thread. The rotating rod 11 is connected to the connecting hole 13 inside the rotating disk 12 by inserting through the slot 14. The upper end of the rotating rod 11 has a through hole for the fixing rod 10. The chassis 15 is connected to the rotating rod 11 by welding. The chassis 15 can drive the rotating rod 11 to rotate by the rotating motor 9. The upper end of the hydraulic rod 7 is connected to the connecting frame 8 by welding. The connecting frame 8 is connected to the cover 2 by bolts.

[0043] Preferably, the device can transmit power by starting the rotating motor 9 after the alloy pellets are placed inside the quenching furnace body, through its connection structure with the connecting frame 8. The output shaft of the rotating motor 9 drives the connected components, thereby causing the rotating disk 12 to rotate. Since the rotating rod 11 is connected to the rotating disk 12 through a special connection structure, the rotation of the rotating disk 12 drives the rotating rod 11 to rotate. Because the base 15 is welded to the rotating rod 11, the rotating rod 11 drives the base 15 to rotate together, thereby driving the storage rack fixed on the base 15 to rotate. Simultaneously with the rotation of the storage rack, the heating wire inside the inner wall of the quenching furnace body 1 is activated to heat the alloy pellets placed on the storage rack, ensuring uniform heating to reach the temperature required for austenitization, and maintaining this temperature for a certain period to achieve fully homogenized microstructure.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
