[0024] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1 , Figure 1 The present invention is a schematic structural diagram of a specific embodiment of the quenching device provided by the present invention in the working position.

[0026] The utility model provides a quenching device, comprising a quenching pool 1, a quenching mechanism 2 and a rotating mechanism 3. The interior of the quenching pool 1 is provided with a quenching medium. The interior of the quenching mechanism 2 is hollow and can accommodate a workpiece to be processed. The quenching mechanism 2 has a liquid inlet hole. The quenching mechanism 2 has at least a working position. When in the working position, the quenching mechanism 2 is located inside the quenching pool 1 and below a liquid level A of the quenching medium. The quenching mechanism 2 and the quenching pool 1 are connected through the liquid inlet hole. The rotating mechanism 3 is transmission-connected to the quenching mechanism 2. The rotating mechanism 3 is constructed to drive the quenching mechanism 2 to rotate.

[0027] The quenching device of the utility model changes the structure of the traditional quenching mechanism 2. The quenching mechanism 2 adopts an internal hollow form. The workpiece to be processed is located inside the quenching mechanism 2. When working, the quenching mechanism 2 is located inside the quenching pool 1 and below the liquid level A of the quenching medium. The quenching mechanism 2 and the quenching pool 1 are connected through a liquid inlet hole, and the quenching medium enters the quenching mechanism 2 through the liquid inlet hole. At the same time, the quenching device of the utility model is further provided with a rotating mechanism 3. The rotating mechanism 3 and the quenching mechanism 2 are transmission-connected. When quenching, the rotating mechanism 3 drives the quenching mechanism 2 to rotate, and the workpiece to be processed can continuously roll inside the quenching mechanism 2, so that each workpiece to be processed is fully in contact with the quenching medium, and the temperature of the quenching medium is made more uniform, thereby obtaining a better quenching effect than the traditional quenching device.

[0028] In addition, since the workpiece to be processed in the quenching device of the utility model is always in a tumbling state during the quenching process, the problem of insufficient contact is avoided, so more workpieces can be processed within a unit area, so that the loading capacity of the quenching mechanism 2 is larger, and more workpieces can be processed at one time, ensuring the heat treatment effect while greatly improving the processing efficiency.

[0029] The quenching medium may be oil or other liquid media.

[0030] Please refer to Figure 1-Figure 4 , Figure 2 for Figure 1 A schematic diagram of the structure of the quenching device from the second angle; Figure 3 for Figure 1 Schematic diagram of the structure of the quenching device at the discharge position; Figure 4 for Figure 1 Schematic diagram of the internal structure of the quenching mechanism in the quenching device.

[0031] The quenching device of the utility model also includes a feed transition bucket 4, a discharge transition bucket 5 and a lifting mechanism 6. The quenching mechanism 2 has a feed port 1 and a discharge port 0. The lifting mechanism 6 is arranged above the quenching pool 1. The lifting mechanism 6 is configured to drive the quenching mechanism 2 and the rotating mechanism 3 to move synchronously in the height direction, so that the quenching mechanism 2 is switched between the working position and the discharge position.

[0032] When the quenching mechanism 2 is in the working position, the feed transition hopper 4 is connected to the feed port I of the quenching mechanism 2. When the quenching mechanism 2 is in the discharging position, the quenching mechanism 2 is lifted above the liquid level A of the quenching medium, and the discharging transition hopper 5 is connected to the discharging port O of the quenching mechanism 2. The quenching mechanism 2 has a conveying mechanism 7 inside, and the conveying mechanism 7 is configured to convey the workpiece to be processed to the discharging transition hopper 5. The feed port I and the discharging port O form at least a portion of the liquid inlet hole.

[0033] The traditional swing quenching device cannot realize the automatic output of the workpiece, and the working efficiency is low. The quenching device of the utility model is equipped with a feed transition bucket 4, a discharge transition bucket 5 and a lifting mechanism 6, and its working process is as follows:

[0034] In the non-working state, the quenching mechanism 2 is in the discharging position, and the quenching mechanism 2 is located above the liquid level A of the quenching medium;

[0035] During operation, the lifting mechanism 6 drives the quenching mechanism 2 and the rotating mechanism 3 to descend synchronously, and the quenching mechanism 2 is completely immersed in the quenching medium. The feed port 1 of the quenching mechanism 2 is connected with the feed transition bucket 4, and the quenching mechanism 2 is connected with the quenching pool 1 through the liquid inlet hole. The quenching medium enters the quenching mechanism 2 through the liquid inlet hole. The rotating mechanism 3 starts and drives the quenching mechanism 2 to rotate, waiting for the workpiece to be processed to enter;

[0036] The workpiece to be processed enters the quenching mechanism 2 from the feed transition hopper 4. The quenching mechanism 2 tumbles the workpiece to be processed at a set rotation speed. After the preset quenching time is reached, the quenching mechanism 2 stops rotating, and the lifting mechanism 6 drives the quenching mechanism 2 and the rotating mechanism 3 to rise synchronously, so that the quenching mechanism 2 is lifted above the liquid level A of the quenching medium, and the discharge port O of the quenching mechanism 2 is connected to the discharge transition hopper 5;

[0037] After the conveying mechanism 7 conveys the workpiece to be processed to the discharge transition hopper, the workpiece to be processed is discharged and waits for the next feeding.

[0038] It can be seen that the quenching device of the utility model is additionally provided with a feed transition bucket 4, a discharge transition bucket 5 and a lifting mechanism 6, which can realize automatic feeding and automatic output of the workpiece to be processed, thereby improving work efficiency.

[0039] In this embodiment, the feed transition hopper 4 and the discharge transition hopper 5 are both arranged in the quenching pool 1, the feed transition hopper 4 is connected to the inner wall of the quenching pool 1, the outlet end of the feed transition hopper 4 extends below the liquid level A of the quenching medium, and the discharge transition hopper 5 is connected to the open end of the quenching pool 1, and the outlet end of the discharge transition hopper 5 extends to the outside of the quenching pool 1. In this way, the relative positions of the feed transition hopper 4, the discharge transition hopper 5 and the quenching pool 1 are determined, ensuring that when the quenching mechanism 2 is in the working position, the feed transition hopper 4 and the feed port I of the quenching mechanism 2 are always connected, and when the quenching mechanism 2 is in the discharge position, the discharge transition hopper 5 and the discharge port O of the quenching mechanism 2 are always connected.

[0040] In practice, there is no limitation on the connection method between the feed transition hopper 4, the discharge transition hopper 5 and the quenching pool 1, such as welding and fixing.

[0041] Please continue to refer to Figure 4 In this embodiment, the feed port I and the discharge port O are located at the axial ends of the quenching mechanism 2, and the conveying mechanism 7 includes a spiral transmission shaft extending along the axial direction of the quenching mechanism 2. The axial end of the spiral transmission shaft extends to the discharge port O and has a spacing with the feed port I. When the rotating mechanism 3 drives the quenching mechanism 2 to rotate in a preset direction, the spiral transmission shaft can convey the workpiece to be processed to the discharge transition bucket 5.

[0042] The quenching mechanism 2 of the utility model can realize the quenching treatment of the workpiece to be processed, or allow the workpiece to be processed to be discharged from the discharge port O of the quenching mechanism 2 through the internal spiral transmission shaft combined with the forward and reverse control of the rotating mechanism 3; specifically, during quenching, the rotating mechanism 3 drives the quenching mechanism 2 to rotate in the forward direction, so that the workpiece to be processed only rolls inside the quenching mechanism 2, and the axial end of the spiral transmission shaft is spaced from the feed port I, so the workpiece to be processed will not escape from the feed port I; after quenching is completed, when the quenching mechanism 2 moves to the discharge position, the rotating mechanism 3 drives the quenching mechanism 2 to rotate in the reverse direction, so that the workpiece to be processed is discharged from the discharge port O under the action of the spiral transmission shaft, and then discharged through the discharge transition bucket 5.

[0043] It can be seen that the utility model realizes the transportation of the workpiece to be processed through the above spiral transmission shaft, has a simple structure and reduces costs.

[0044] Please continue to refer to Figure 1-Figure 3 The quenching device of the utility model also includes a lifting frame 8 and a fixed frame 9. The lifting mechanism 6 is installed on the fixed frame 9. The output shaft of the lifting mechanism 6 can be extended and retracted in the height direction. The output shaft of the lifting mechanism 6 is connected to the lifting frame 8. The quenching mechanism 2 and the rotating mechanism 3 are both installed on the lifting frame 8.

[0045] As configured above, the fixed frame 9 is used to fix the lifting mechanism 6, the output shaft of the lifting mechanism 6 is connected to the lifting frame 8, and the output shaft of the lifting mechanism 6 is retracted in the height direction, so that the lifting frame 8 can be lifted and lowered in the height direction. The quenching mechanism 2 and the rotating mechanism 3 are both installed on the lifting frame 8, thereby realizing the lifting and lowering of the quenching mechanism 2 and the rotating mechanism 3 in the height direction, and realizing the position switching of the quenching mechanism 2; at the same time, the quenching mechanism 2 and the rotating mechanism 3 are both installed on the lifting frame 8, and the relative positions of the two are fixed, thereby ensuring that the transmission connection between the quenching mechanism 2 and the rotating mechanism 3 is reliable.

[0046] Among them, the lifting mechanism 6 can be a power mechanism such as a hydraulic cylinder / air cylinder / electric cylinder that can produce linear displacement. The cylinder body of the hydraulic cylinder / air cylinder / electric cylinder is fixed to the fixed frame 9, and the push rod of the hydraulic cylinder / air cylinder / electric cylinder extends along the height direction. The push rod of the hydraulic cylinder / air cylinder / electric cylinder is connected to the lifting frame 8.

[0047] In practice, the fixing frame 9 may be directly connected to the quenching tank 1 to be fixed relative to the quenching tank 1 ; or, the lower end of the fixing frame 9 may be fixed to the ground to be fixed relative to the quenching tank 1 .

[0048] Please continue to refer to Figure 3 The quenching device of the present invention further includes a guide portion 10 and a matching portion 11. The guide portion 10 is arranged on the fixed frame 9 and extends along the height direction. The matching portion 11 is arranged on the lifting frame 8. The guide portion 10 and the matching portion 11 are slidably matched or rolling matched.

[0049] As configured above, the quenching device of the utility model realizes the guiding and positioning of the lifting frame 8 through the sliding or rolling cooperation between the guide part 10 and the matching part 11, ensuring that the lifting frame 8 always moves along the extension direction of the guide part 10 during the lifting process, thereby improving the position accuracy of the lifting frame 8 during the movement process.

[0050] The guide portion 10 may be a guide column, and the matching portion 11 may be a guide wheel, a guide slider, etc. The guide wheel and the guide column are in rolling cooperation, and the guide slider and the guide column are in sliding cooperation.

[0051] In practice, the guide column and the fixing frame 9 can be an integral structure or a separate structure, and then fixed together, such as by welding or by connecting members such as bolts. The matching portion 11 and the lifting frame 8 can be fixed by connecting members such as bolts.

[0052] Please refer to Figure 5 , Figure 5 for Figure 1 Schematic diagram of the structure of the quenching mechanism in the quenching device.

[0053] In the utility model, one or more hole groups are arranged on the peripheral wall of the quenching mechanism 2, and the plurality of hole groups are spaced apart along the circumference of the quenching mechanism 2. The hole groups include one or more hole portions a, and the plurality of hole portions a are spaced apart along the axial direction of the quenching mechanism 2, and the hole portions a form part of the liquid inlet hole.

[0054] In this way, the hole portion a arranged on the peripheral wall of the quenching mechanism 2 and the discharge port O together form a liquid inlet hole, and the quenching medium enters the interior of the quenching mechanism 2 through the liquid inlet hole, which can improve the liquid inlet efficiency.

[0055] Please continue to refer to Figure 1-Figure 3 In the utility model, the rotating mechanism 3 includes a rotating motor 31, two transmission wheels 32 and a transmission chain 33. The rotating motor 31 is installed on the lifting frame 8 and is located above the quenching mechanism 2. One of the transmission wheels 32 is connected to the output end of the rotating motor 31, and the other transmission wheel 32 is sleeved on the outer periphery of the quenching mechanism 2. The transmission chain 33 connects the two transmission wheels 32.

[0056] As configured above, the output end of the rotating motor 31 drives the corresponding transmission wheel 32 to rotate, and the transmission chain 33 connects the two transmission wheels 32. Under the connection of the transmission chain 33, the two transmission wheels 32 rotate synchronously, thereby realizing the rotation of the quenching mechanism 2.

[0057] In practice, it is also feasible that the two transmission wheels 32 mesh with each other. In this case, there is no need to set the transmission chain 33. Of course, by realizing the transmission connection of the two transmission wheels 32 through the transmission chain 33, the size of the transmission wheel 32 can be reduced, and the height distance between the rotating motor 31 and the quenching mechanism 2 can be increased, so that when working, the quenching mechanism 2 is completely immersed in the quenching medium, and the rotating motor 31 is located above the liquid level A of the quenching medium, ensuring the normal operation of the rotating motor 31.

[0058] In addition, in practice, the transmission chain 33 can also be in the form of a transmission belt or the like.

[0059] Please continue to refer to Figure 2 The quenching device of the present invention also includes a support portion 12 arranged on the lifting frame 8, the support portion 12 is close to the lower side of the quenching mechanism 2, and the support portion 12 includes a rotatable support wheel 121, and the peripheral wall of the support wheel 121 is in rolling contact with the peripheral wall of the quenching mechanism 2.

[0060] As configured above, the support portion 12 can play a supporting role for the quenching mechanism 2, and the support portion 12 includes a rotatable support wheel 121, and the peripheral wall of the support wheel 121 is in rolling contact with the peripheral wall of the quenching mechanism 2, which can reduce the friction of the support wheel 121 during the rotation of the quenching mechanism 2 and ensure the smooth rotation of the quenching mechanism 2.

[0061] Depend on Figure 2 and Figure 3It can be seen that in this embodiment, the number of the support parts 12 is four, two of which form a support assembly, and the two support parts 12 in the same support assembly are located on both sides of the radial direction of the quenching mechanism 2, and the support assemblies are distributed at intervals along the axial direction of the quenching mechanism 2. It can be understood that in practice, the number of support assemblies is not limited, such as the number of support assemblies can be more than two.

[0062] Please continue to refer to Figure 4 and Figure 5 In this embodiment, the quenching mechanism 2 includes a column section 21 and a cone section 22 connected to both axial ends of the column section 21 , and the diameter of the cone section 22 gradually decreases in a direction away from the column section 21 .

[0063] It can be seen that the lower wall surface of the cone section 22 extends upwardly and obliquely away from the column section 21. During feeding, the workpiece to be processed can enter the interior of the column section 21 along the wall surface of the cone section 22 under the action of gravity. The workpiece to be processed has sufficient power to slide toward the direction close to the discharge port O, thereby avoiding that all the workpieces to be processed are piled up at the feed port I, thereby increasing the loading capacity of the workpieces to be processed in the quenching mechanism 2. During quenching, the wall surface of the cone section 22 can also play a blocking role, preventing the workpiece to be processed from escaping from the feed port I.

[0064] The quenching method of the quenching device of the utility model comprises the following steps:

[0065] Switch the quenching mechanism 2 to the working position, so that the feed port 1 of the quenching mechanism 2 is connected to the feed transition hopper 4, and the quenching medium in the quenching pool 1 enters the quenching mechanism 2 through the liquid inlet hole;

[0066] The quenching mechanism 2 is controlled to rotate forward, and the workpiece to be processed is transferred from the feed transition hopper 4 to the inside of the quenching mechanism 2, so that the workpiece to be processed rolls inside the quenching mechanism 2. After the preset quenching time is reached, the quenching mechanism 2 is controlled to stop rotating;

[0067] The quenching mechanism 2 is switched to the discharging position, and the quenching mechanism 2 is controlled to rotate in the reverse direction, and the workpiece to be processed is conveyed to the discharging transition hopper 5 through the conveying mechanism 7 and then discharged.

[0068] In practice, the above-mentioned preset quenching time and the rotation speed of the quenching mechanism 2 can be set according to the heat treatment requirements of different products.

[0069] Among them, in the above quenching method, the quenching mechanism 2 is first controlled to rotate forward, and then the material is fed. In practice, it is also feasible to feed the material first and then control the quenching mechanism 2 to rotate forward. Of course, the quenching mechanism 2 is first controlled to rotate forward, and then the material is fed. In terms of process, the temperature of the quenching medium is more uniform, and the workpiece to be processed is fully in contact with the quenching medium during the process of entering the quenching mechanism 2, and the quenching effect is better, which is a more preferred technical solution.

[0070] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
