[0002] Vacuum quenching refers to the process of heating a metal workpiece to above the critical temperature in a vacuum environment, and then rapidly cooling it after proper heat preservation. The principle is that the vacuum environment can effectively reduce the contact of the workpiece with the external gas during the heating and cooling process, avoid the occurrence of undesirable phenomena such as oxidation and decarburization, and thus better achieve precise control of the workpiece structure.

[0003] Reference to the authorized announcement number "CN101586225B" discloses a vacuum quenching method and a vacuum quenching device used therein, which records: "The parts to be quenched are loaded into a vacuum furnace tube for heating; during quenching, the furnace tube is turned over so that the tube mouth of the furnace tube is completely immersed in the water of the quenching tank, and the sealing flange is opened so that the parts are directly dropped from the furnace tube into the quenching liquid for quenching in a state isolated from the air. A turning mechanism is used to achieve rapid transfer, and the existing transfer time of 12 seconds is shortened to a transfer time of less than or equal to 3 seconds. During the heating and cooling process, the parts do not contact the air, successfully solving the problem of parts being contaminated by oxygen, hydrogen, carbon, and nitrogen. The ultimate vacuum in the cold state can reach 1.0×10-3Pa, and the working vacuum when kept at 950℃ can reach 3.2×10-3Pa. It also has the characteristics of simple operation, high degree of automation, and strong practicality." Technical problems.

[0049] When in use, the workpiece is placed on the top of the two first support frames 4, and then the blocking component 5 is opened, and the box body 1 is in an open state. The workpiece is driven to the inside of the box body 1 by controlling the driving component 6, and then the blocking component 5 is opened, and the box body 1 is in a closed state, and the vacuum exhaust module 2 is opened, and the inside of the box body 1 is in a vacuum state. The workpiece is driven to be inserted into the inside of the quenching component 7 by the setting of the driving component 6, and the workpiece is heated and cooled by the setting of the quenching component 7, thereby completing the quenching operation;

At the same time, the first fixing rod 11 is set to improve the stability of the first blocking door 12 moving between the two first groove plates 8.

[0053] When the first blocking door 12 moves to the top of the circulation port, it can easily drive the component 6 to bring the workpiece into or out of the inside of the box 1 through the circulation port.

A first movable plate 18 is arranged between the two second groove plates 14, and one side of the first movable plate 18 extends to the inner side of the second groove plate 14 and is threadedly connected to the second screw 16, and the other side of the first movable plate 18 extends to the inner side of the other second groove plate 14 and is slidably connected to the second fixed rod 17.

[0057] The driving assembly 6 also includes a third motor 19, a turntable 20, a driving transverse plate 21, a supporting vertical plate 22, a rotating right-angle plate 23, a fourth motor 24 and a rotating connecting plate 25. The third motor 19 is fixedly connected to the center position of the top of the first movable plate 18, and the output end of the top of the third motor 19 is fixedly connected to the turntable 20. The top of the turntable 20 is fixedly connected to the driving transverse plate 21, and both sides of the top of the driving transverse plate 21 are fixedly connected to the supporting vertical plates 22. The sides of the two supporting vertical plates 22 that are close to each other are rotatably connected to the rotating right-angle plate 23. One of the supporting vertical plates 22 is fixedly connected to the side away from the rotating right-angle plate 23 with the fourth motor 24, and the output end of the fourth motor 24 passes through the supporting vertical plates 22 and is rotatably connected to the corresponding rotating right-angle plate 23. The tops of the two rotating right-angle plates 23 that are close to each other are rotatably connected to the rotating connecting plate 25.

The rotating shafts 27 are fixedly connected to both sides of the movable plate 26, and the rotating shafts 27 are rotatably connected to the corresponding lower part of the rotating connecting plate 25. One end of the movable plate 26 is fixedly connected to multiple supporting plates 28, and the multiple supporting plates 28 are clearance-matched with the two first support frames 4. An extended supporting plate 29 is fixedly connected to the bottom of the movable plate 26. Guide grooves are provided on both sides of the extended supporting plate 29, and the end of the guide groove close to the supporting plate 28 is open.

[0059] Specifically: by turning on the fourth motor 24, one of the rotating right-angle plates 23 can be driven to rotate. When the rotating right-angle plate 23 rotates, the position where the rotating right-angle plate 23 is rotatably connected to the rotating connecting plate 25 can be driven to move with the fourth motor 24 as the center, thereby driving the rotating connecting plate 25 to move synchronously;

[0060] When the rotating connecting plate 25 moves downward, since the bottom of the rotating connecting plate 25 is rotatably connected to the rotating shaft 27, and the rotating shaft 27 can only move laterally with the moving plate 26, the rotating connecting plate 25 can be turned over, so that the moving plate 26 can be pushed to move toward the end away from the supporting vertical plate 22 by the rotating connecting plate 25.

[0061] When the movable plate 26 moves toward the end away from the supporting vertical plate 22, the extended support plate 29 at the bottom can be driven to move synchronously between the two fixed plates 30. At the same time, the guide grooves opened on both sides of the extended support plate 29 will wrap the outer side of the limiting column 31 through the opening position of the guide groove. The setting of the limiting column 31 and the guide groove can limit the movement of the extended support plate 29. At the same time, the setting of the extended support plate 29 can support the bottom of the movable plate 26 after it is extended, so as to further improve the stability of the support plate 28 in supporting the workpiece.

[0062] By turning on the second motor 15, the second screw 16 can be driven to rotate inside the second groove plate 14, so that the first movable plate 18 threadedly connected to the second screw 16 can be driven to move up and down between the two second groove plates 14. At the same time, the second fixing rod 17 can be set to improve the stability of the first movable plate 18 when moving;

[0063] After the workpiece is placed on top of the two first support frames 4, the support plate 28 can be controlled to extend between the two first support frames 4, and then the support plate 28 can be driven to move upward to lift the workpiece, and then the support plate 28 can be driven to move toward one end close to the support vertical plate 22 to drive the workpiece to move to the top of the support vertical plate 22;

[0064] By turning on the third motor 19 , the turntable 20 can be driven to rotate on the top of the first movable plate 18 , so that the orientation of the supporting plate 28 can be adjusted, making it easier for the supporting plate 28 to drive the workpiece to quench and move the workpiece out of the box body 1 .

[0065] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.
