Description

Technical Field

[0001] This utility model relates to the technical field of quenching devices, specifically a stirring device for an isothermal quenching tank of high-speed tool steel. Background Technology

[0002] The heat treatment process for high-speed steel is relatively complex, requiring a series of processes including quenching and tempering. During quenching, the steel is first preheated to 800–850℃ (to avoid excessive thermal stress), then rapidly heated to the quenching temperature of 1190–1290℃ (the actual temperature varies depending on the grade). Afterward, it is cooled by oil, air, or gas. Stirring the quenching tank is a crucial step in the heat treatment process to ensure uniform mixing of the quenching medium, directly affecting the cooling effect and quenching quality of the workpiece.

[0003] A vertical stirrer for a quenching tank, disclosed in CN218842252U, includes a stirring assembly and a base assembly for mounting the stirring assembly. The stirring assembly includes a disc, an extension rod integrally formed on the outer wall of the disc, and a stirring motor mounted on the disc. A transmission shaft is coaxially mounted on the output shaft of the stirring motor, and a transmission assembly is movably mounted on the transmission shaft. A stirring shaft and stirring blades are mounted below the transmission assembly. By setting an adjustable transmission assembly and a disc that can be rotated by a rotating motor, the position of the stirring shaft can be flexibly adjusted, and the stirring blades can also rotate around the center of the top of the quenching tank during their rotation, effectively improving the stirring efficiency and facilitating use in the quenching tank.

[0004] However, the patent still has the following problems in actual use: the device can change the stirring position, but it is not convenient to adjust the stirring depth, resulting in poor stirring effect of the quenching liquid at the bottom of the quenching tank, making it difficult to maintain the overall uniform distribution of the quenching liquid, reducing the cooling effect and quenching quality of the subsequent high-speed steel, and thus has limitations.

[0005] Therefore, a stirring device for a high-speed tool steel isothermal quenching tank is proposed to solve the problems mentioned above. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stirring device for an isothermal quenching tank of high-speed tool steel, comprising a tank body and support legs fixedly installed at the bottom of the tank body, wherein cylinders are symmetrically fixedly installed on the outer side of the tank body;

[0008] An internal gear ring is fixedly connected to the telescopic end of the cylinder, and a cylinder is fixedly connected to the top of the internal gear ring.

[0009] Also includes:

[0010] A top plate is fixedly connected to the top of the cylinder, a servo motor is fixedly installed at the bottom of the top plate, a main gear is fixedly connected to the output end of the servo motor, a main stirring rod is fixedly connected to the bottom of the main gear, an annular disk is rotatably installed on the inner side of the cylinder, and multiple slave gears are rotatably installed at the bottom of the annular disk, the slave gears meshing with the main gear.

[0011] The gear is fixedly connected to a side stirring rod at the bottom, and a reciprocating screw is fixedly connected to the bottom of the side stirring rod. A collar is sleeved on the outside of the reciprocating screw.

[0012] The collar is threadedly connected to the reciprocating lead screw, and the same inner ring body is fixedly connected to the inner side of the collar. Vertical rods are symmetrically fixedly connected to the inner side of the inner ring body.

[0013] Preferably, there are at least two cylinders, and the output end of each cylinder is fixedly connected to the same internal gear ring, which is located above the groove.

[0014] Preferably, the servo motor is located at the bottom center of the top plate, a circular groove is formed in the center of the annular disk, the servo motor is located inside the circular groove, and a sliding plate is symmetrically fixedly connected to the outer ring of the annular disk.

[0018] Preferably, there are at least four horizontal bars, and the vertical bar is located below the main stirring rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a servo motor, main gear, main stirring rod, annular disk, vertical shaft, driven gear, side stirring rod, reciprocating screw, inner ring body, and vertical rod, the main stirring rod stirs the upper center position of the quenching liquid, the side stirring rod stirs the upper side position of the quenching liquid, and the vertical rod stirs the lower part of the quenching liquid, thereby achieving the stirring treatment of the entire internal position of the quenching liquid, maintaining the uniform mixing of the quenching liquid, and improving the cooling effect and quenching quality of high-speed steel. The specific details are as follows:

[0020] The tank is equipped with a servo motor, main gear, main stirring rod, annular disk, vertical shaft, driven gear, side stirring rod, reciprocating screw, inner ring body, and vertical rod. The tank is filled with quenching liquid, specifically ACR quenching liquid. The operator starts the servo motor, which drives the main gear and main stirring rod to rotate. The main stirring rod stirs the quenching liquid at its center, while the main gear drives the surrounding driven gears to rotate. The driven gears drive the vertical shaft to rotate, meshing with the inner gear ring. All three driven gears are mounted on the bottom of the same annular disk, causing them to revolve around each other. The wheel drives the side stirring rod and the reciprocating screw to rotate, and the side stirring rod and the reciprocating screw also revolve around the sun. The side stirring rod stirs the upper side of the quenching liquid, causing the reciprocating screw to drive the collar and the inner ring to revolve around the sun. Since the inner ring cannot rotate, the rotation of the reciprocating screw causes the collar to move back and forth in a straight line. The inner ring will revolve around the sun and move up and down. The inner ring will drive the vertical rod to revolve around the sun and move up and down. The vertical rod stirs the lower part of the quenching liquid, thereby achieving the stirring treatment of the entire internal position of the quenching liquid, keeping the quenching liquid mixed evenly, and improving the cooling effect and quenching quality of high-speed steel.

[0021] By setting up a cylinder, internal gear ring, cylinder, slide plate, and chute, during subsequent quenching, the cylinder extends, causing the internal gear ring to rise. The operator can then remove the fixing bolts between the internal gear ring and the cylinder to disassemble the component, thus facilitating the subsequent quenching operation of high-speed steel. When the vertical shaft and the driven gear revolve, the vertical shaft drives the annular disk to rotate, and the annular disk drives the slide plate to rotate. The slide plate slides inside the chute, maintaining the stable revolution of the vertical shaft and the driven gear, thereby maintaining the revolution and stirring treatment of the side stirring rod and maintaining the uniformity and stability of the stirring of the quenching liquid.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 7 The present invention provides a technical solution: a stirring device for a high-speed tool steel isothermal quenching tank, comprising a tank body 1 and support legs 2 fixedly installed at the bottom of the tank body 1, and cylinders 3 symmetrically fixedly installed on the outer side of the tank body 1.

[0032] An internal gear ring 4 is fixedly connected to the telescopic end of cylinder 3. A cylinder 5 is fixedly connected to the top of the internal gear ring 4. There are at least two cylinders 3, and the output end of cylinder 3 is fixedly connected to the same internal gear ring 4. The internal gear ring 4 is located above the tank 1. During subsequent quenching, cylinder 3 extends and drives the internal gear ring 4 to rise. The operator can remove the fixing bolts between the internal gear ring 4 and cylinder 3 to remove the component, which facilitates the subsequent quenching operation of high-speed steel.

[0033] A top plate 6 is fixedly connected to the top of the cylinder 5. A servo motor 7 is fixedly installed at the bottom of the top plate 6. A main gear 8 is fixedly connected to the output end of the servo motor 7. A main stirring rod 9 is fixedly connected to the bottom of the main gear 8. An annular disk 10 is rotatably installed on the inner side of the cylinder 5. Multiple slave gears 14 are rotatably installed at the bottom of the annular disk 10. The slave gears 14 mesh with the main gear 8.

[0034] The servo motor 7 is located at the bottom center of the top plate 6. A circular groove is opened in the center of the annular disk 10, and the servo motor 7 is located inside the circular groove. The outer ring of the annular disk 10 is symmetrically and fixedly connected with the sliding plate 11.

[0035] There are at least three slide plates 11. A groove 12 is provided on the upper inner side of the cylinder 5. The slide plates 11 are slidably connected to the groove 12. A vertical shaft 13 is fixedly connected to the top of the gear 14. When the vertical shaft 13 and the gear 14 revolve, the vertical shaft 13 drives the annular disk 10 to rotate, and the annular disk 10 drives the slide plates 11 to rotate. The slide plates 11 slide inside the groove 12, keeping the vertical shaft 13 and the gear 14 revolve stably, thereby maintaining the revolve stirring treatment of the side stirring rod 15 and maintaining the uniformity and stability of the stirring of the quenching liquid.

[0036] A side stirring rod 15 is fixedly connected to the bottom of the gear 14, and a reciprocating screw 16 is fixedly connected to the bottom of the side stirring rod 15. A collar 17 is sleeved on the outside of the reciprocating screw 16.

[0037] The top of the vertical shaft 13 is rotatably connected to the annular disk 10. The driven gear 14 is located inside the internal gear ring 4. There are no fewer than three driven gears 14, and the driven gears 14 are meshed with the internal gear ring 4.

[0038] The collar 17 is threadedly connected to the reciprocating lead screw 16. The inner side of the collar 17 is fixedly connected to the same inner ring body 18, and the inner side of the inner ring body 18 is symmetrically fixedly connected to the vertical rod 20.

[0039] The interior of tank 1 is filled with quenching liquid, which is ACR quenching liquid. The operator starts the servo motor 7, which drives the main gear 8 and the main stirring rod 9 to rotate. The main stirring rod 9 stirs the quenching liquid at the center of the top. The main gear 8 drives the surrounding driven gears 14 to rotate. The driven gears 14 drive the vertical shaft 13 to rotate. The driven gears 14 mesh with the internal gear ring 4. The three driven gears 14 are rotatably mounted on the bottom of the same annular disk 10, so that the driven gears 14 will also revolve. The driven gears 14 drive the side stirring rod 15 and the reciprocating screw 16 to rotate.

[0040] The side stirring rod 15 and the reciprocating screw 16 also revolve. The side stirring rod 15 stirs the upper side of the quenching liquid, causing the reciprocating screw 16 to drive the collar 17 and the inner ring 18 to revolve. Since the inner ring 18 cannot rotate on its own axis, the rotation of the reciprocating screw 16 causes the collar 17 to move back and forth in a straight line. The inner ring 18 will revolve and move up and down. The inner ring 18 drives the vertical rod 20 to revolve and move up and down. The vertical rod 20 stirs the lower part of the quenching liquid, thereby achieving the stirring treatment of the entire internal position of the quenching liquid, keeping the quenching liquid mixed evenly, and improving the cooling effect and quenching quality of high-speed steel.

[0041] The collar 17 is located below the side stirring rod 15. The number of collars 17 is the same as that of the driven gear 14. The inner side of the inner ring body 18 is symmetrically fixedly connected with crossbars 19. The end of the crossbar 19 away from the inner ring body 18 is fixedly connected to the vertical rod 20. There are no fewer than four crossbars 19. The vertical rod 20 is located below the main stirring rod 9.

[0042] Working principle:

[0043] Before using this type of high-speed tool steel isothermal quenching tank stirring device, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 7 As shown, the interior of tank 1 is filled with quenching liquid, specifically ACR quenching liquid. The operator starts the servo motor 7, which drives the main gear 8 and the main stirring rod 9 to rotate. The main stirring rod 9 stirs the quenching liquid at its upper center position. The main gear 8 drives the surrounding driven gears 14 to rotate, which in turn drives the vertical shaft 13 to rotate. The driven gears 14 mesh with the internal gear ring 4, and the three driven gears 14 are rotatably mounted on the bottom of the same annular disk 10, causing them to revolve. The vertical shaft 13 drives the annular disk 10 to rotate, which in turn drives the sliding plate 11 to rotate. The sliding plate 11 slides inside the chute 12, maintaining stable revolution of the vertical shaft 13 and the driven gears 14. The driven gears 14 drive the side stirring rod 15 and the reciprocating screw 16 to rotate. The reciprocating screw 16 also revolves around the quenching liquid, and the side stirring rod 15 stirs the upper side of the quenching liquid, causing the reciprocating screw 16 to drive the collar 17 and the inner ring 18 to revolve. Since the inner ring 18 cannot rotate on its own axis, the rotation of the reciprocating screw 16 causes the collar 17 to move back and forth in a straight line, and the inner ring 18 to revolve and move up and down. The inner ring 18 drives the vertical rod 20 to revolve and move up and down, and the vertical rod 20 stirs the lower part of the quenching liquid, thereby achieving the stirring treatment of the entire position inside the quenching liquid, keeping the quenching liquid mixed evenly, improving the cooling effect and quenching quality of high-speed steel. During subsequent quenching, the cylinder 3 extends and drives the internal gear ring 4 to rise. The operator can remove the fixing bolts between the internal gear ring 4 and the cylinder 3 to remove the component, thus facilitating the subsequent quenching operation of high-speed steel.

[0044] Although the present invention 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 invention should be included within the protection scope of the present invention.
