[0002] A bucket tooth quenching device is a specialized device for quenching bucket teeth (such as gears or tooth-shaped components in mining machinery and engineering machinery). Quenching involves rapidly heating to a specific temperature and then quickly cooling to improve the hardness and wear resistance of the metal material. Bucket tooth quenching devices are mainly used to improve the wear resistance of bucket teeth, extend their service life, and enhance their performance under heavy load conditions. For example, a bucket tooth quenching device disclosed in patent application number CN202321083218.9 relates to the field of bucket tooth processing. This bucket tooth quenching device includes a housing, with a slidingly connected partition plate inside the housing. A filter screen is installed inside the partition plate and is adapted to fit the partition plate. A sleeve is installed inside the housing, with a threaded rod inside the sleeve. A rotating block is rotatably connected to the top of the threaded rod, and the rotating block is fixedly connected to the filter screen. Multiple blades are fixedly connected to the outside of the sleeve.

[0003] The existing bucket tooth processing quenching device has a poor cooling effect on the quenching agent during use, and the temperature of the quenching agent is prone to rise during long-term use, which affects the quenching effect on the workpiece. In addition, the method of handling impurities generated during the quenching process is limited, and impurities are prone to affecting the quenching effect during long-term operation, thus reducing the quenching quality of the workpiece. Therefore, it is necessary to make improvements. Utility Model Content

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.

[0047] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0048] Example 1:

[0049] This application provides a bucket tooth processing quenching device, including: a base 1, and a quenching box 2 disposed on the base 1;

[0050] It also includes: a cooling box 3, which is mounted on the base 1 and located on one side of the quenching box 2, and contains an impurity treatment component 4 and a quenching agent cooling component 5; a quenching agent delivery pipeline 6, on which a delivery pump is connected in series, one end of which is connected to the top of the quenching box 2 and the other end is connected to the quenching agent cooling component 5; a quenching agent recovery pipeline 7, on which a recovery pump is connected in series, one end of which is connected to the bottom of the quenching box 2 and the other end is connected to the top of the cooling box 3; and a filter plate 8, which is detachably mounted in the quenching box 2 and located at the bottom of the quenching box 2.

[0051] The connection between the quenching agent recovery pipeline 7 and the quenching box 2 is located below the filter plate 8, and the impurity treatment component 4 is located above the quenching agent cooling component 5.

[0052] Moreover, both the delivery pump and the return pump are conventional pumps. The filter plate 8 can be detachably installed in the quenching chamber 2 in a conventional manner. For example, an insertion hole is provided on the side wall of the quenching chamber 2, which extends through to the inner wall of the quenching chamber 2. A plate seat is inserted into the insertion hole, and the inner end of the plate seat is located inside the quenching chamber 2 and connected to one side of the filter plate 8. A support plate is installed on the inner wall of the quenching chamber 2 on the side opposite to the insertion hole. The side of the filter plate 8 away from the plate seat can be placed on the support plate. The plate seat and the insertion hole can be sealed by a conventional sealing strip.

[0053] In this embodiment, during the bucket tooth quenching process, the bucket teeth awaiting quenching are placed in the quenching chamber 2. The bucket teeth are quenched by the quenching agent in the quenching chamber 2. During use, impurities generated during quenching can settle to the bottom under the action of gravity. Larger impurities are filtered by the filter plate 8 during the settling process. At the same time, the quenching agent recovery pipeline 7 transports the quenching agent containing fine impurities to the cooling chamber 3. The impurity treatment component 4 in the cooling chamber 3 can further treat the impurities in the quenching agent. Then, after being cooled by the quenching agent cooling component 5, the quenching agent is transported to the quenching chamber 2 by the quenching agent delivery pipeline 6, thereby realizing the circulation of the quenching agent. Compared with the prior art, this utility model can effectively improve the cooling effect of the quenching agent by setting the quenching agent cooling component 5, and improve the quenching quality of the bucket teeth by reducing the impurity content in the quenching agent.

[0054] Example 2:

[0055] This embodiment provides a bucket tooth processing quenching device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the impurity treatment component 4 further includes: a frustum-shaped shell 40, which is disposed in the cooling box 3 and divides the cooling box 3 into an upper cavity 30 and a lower cavity 31; a stirring motor 41, which is disposed inside the frustum-shaped shell 40 and has its drive end extending vertically upward through the frustum-shaped shell 40; a stirring part 9, which is disposed on the drive end of the stirring motor 41; a rotating ring 42, which is rotatably disposed on the platform of the frustum-shaped shell 40 and has a first drain hole 43; and a pressure plate 44, which is disposed on the rotating ring 42.

[0056] The frustum-shaped shell 40 has a second leak hole 45 on its platform. When the rotating ring 42 is in its natural state, the first leak hole 43 and the second leak hole 45 are separated. When the pressure plate 44 is under pressure, the rotating ring 42 can rotate around the central axis of the stirring motor 41 with a limited stroke and align the first leak hole 43 and the second leak hole 45.

[0057] Furthermore, a guide block is provided at the bottom of the rotating ring 42, and an arc-shaped guide groove is provided on the platform of the frustum-shaped shell 40. The arc-shaped guide groove is concentrically distributed with the stirring motor 41. An arc-shaped spring is installed in the arc-shaped guide groove. The guide block is slidably disposed in the arc-shaped guide groove. One end of the arc-shaped spring is connected to the guide block, and the other end is connected to the inner wall of the end of the arc-shaped guide groove. The pressure plate 44, the first leakage hole 43, and the second leakage hole 45 can each have several and are evenly distributed along the circumference of the stirring motor 41. The second leakage hole 45 is connected to the interior of the frustum-shaped shell 40.

[0058] In this embodiment, after the quenching agent enters the cooling box 3 through the quenching agent recovery pipe 7, the quenching agent first enters the upper cavity 30 and accumulates there. During the quenching operation, the stirring motor 41 is started, which drives the quenching agent in the upper cavity 30 to move. As the quenching agent accelerates its rotation, impurities in the quenching agent move to the edge of the upper cavity 30 under the action of centrifugal force, and eventually gradually settle to the bottom edge of the frustum-shaped shell 40 under the action of gravity. At the same time, the pressure plate 44 is subjected to pressure as the quenching agent accelerates its rotation, and under the action of pressure, it drives the rotating ring 42 to rotate. After the rotating ring 42 rotates, the first leakage hole 43 and the second leakage hole 45 are aligned, thereby connecting the upper cavity 30 with the interior of the frustum-shaped shell 40. The central part of the quenching agent enters the interior of the frustum-shaped shell 40 through the first leakage hole 43 and the second leakage hole 45. Compared with the prior art, this utility model can effectively treat the impurities contained in the quenching agent, thereby reducing the impact of impurities on the quenching operation and improving the quenching effect of the bucket teeth.

[0059] Example 3:

[0060] This embodiment provides a quenching device for gear teeth processing. In addition to the technical solutions of the above embodiments, it also has the following technical features: the quenching agent cooling component further includes: a guide funnel 50, which is disposed at the bottom of the frustum-shaped shell 40; a conveying coil 51, which is disposed in the lower cavity 31; a cooling water inlet pipe 52, which is disposed on the side wall of the cooling box 3 and communicates with the lower cavity 31; and a cooling water outlet pipe 53, which is disposed on the side wall of the cooling box 3 and communicates with the lower cavity 31.

[0061] One end of the conveying coil 51 is connected to the outlet of the guide funnel 50, and the other end is connected to the quenching agent conveying pipeline 6.

[0062] In this embodiment, the quenching agent that enters the frustum-shaped shell 40 continues to move downwards and is guided into the delivery coil 51 by the guide funnel 50. At the same time, the cooling water inlet pipe 52 and the cooling water outlet pipe 53 work together to fill the lower cavity 31 with external cooling water and completely surround the delivery coil 51. During the process of the quenching agent moving through the delivery coil 51 to the quenching agent outlet pipe, the quenching agent exchanges heat with the cooling water, thereby reducing the temperature of the quenching agent. Compared with the prior art, this utility model can effectively reduce the temperature of the quenching agent and prevent the temperature of the quenching agent from rising during long-term use, without the need for frequent replacement of the quenching agent.

[0063] Example 4:

[0064] This embodiment provides a bucket tooth machining quenching device. In addition to the technical solutions of the above embodiments, it also has the following technical features: the stirring part 9 further includes: a fixed stirring plate 90, which is disposed at the drive end of the stirring motor 41, and has two plates that are symmetrically distributed radially along the drive end of the stirring motor 41; a movable groove 91, which is disposed at the outer end of the fixed stirring plate 90, and has an elastic telescopic rod 92 disposed in the movable groove 91; and a movable stirring plate 93, which is inserted into the movable groove 91.

[0065] The movable stirring plate 93 can move radially along the drive end of the stirring motor 41, and one end of the elastic telescopic rod 92 is connected to the movable stirring plate 93, while the other end is connected to the inner wall of the movable tank 91.

[0066] Moreover, the elastic telescopic rod 92 can be a conventional structure, such as consisting of a fixed rod and a movable rod. The fixed rod has a groove to accommodate the movable rod, and a spring is installed in the groove. The movable rod is movably inserted into the groove. One end of the spring is connected to the movable rod, and the other end is connected to the inner wall of the groove. The damping rod 94 can cover a rod with a piston cavity 940 and a piston rod 943. A piston plate 941 is installed in the piston cavity 940. Several damping holes 942 are opened on the piston plate 941. One end of the piston rod 943 is connected to the piston plate 941, and the other end passes through the piston cavity 940 and is connected to the movable stirring plate 93. The piston cavity 940 is filled with a damping medium.

[0067] In this embodiment, after the stirring motor 41 starts, as the rotation speed increases, the centrifugal force on the movable stirring plate 93 gradually increases, eventually overcoming the tension of the elastic telescopic rod 92 and moving outward from the movable slot 91. This increases the stirring force-bearing surface of the stirring part 9. By setting the movable stirring plate 93, the stirring part 9 has a smaller stirring force-bearing surface during the starting phase of the stirring motor 41, effectively reducing the starting load of the stirring motor 41 and reducing the phenomenon of starting overload of the stirring motor 41. At the same time, by setting the damping rod 94, when the piston plate 941 moves under the drive of the piston rod 943, it forms small hole damping through the damping hole 942 in cooperation with the medium. This prevents the movable stirring plate 93 from vibrating due to the elastic telescopic rod 92 during the unfolding and resetting process, thus improving the activity stability of the movable stirring plate 93.

[0068] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
