Description

Technical Field

[0001] The utility model relates to the technical field of metal heat treatment, and more precisely to a quenching device for track links. Background Art

[0002] The quenching process is a commonly used heat treatment process. The treatment method is to heat the metal workpiece to a temperature above the critical temperature, hold it for a period of time, and then cool it at a rate greater than the critical cooling rate to obtain a product that meets the corresponding performance requirements. Currently, the quenching process is generally completed through a quenching tank. A quenching tank is a container for holding a quenching medium, and it can be divided into a quenching oil tank, a quenching water tank, a quenching brine tank, a quenching liquid tank, etc. according to the different quenching media. The workpiece to be quenched slides into the quenching tank for rapid cooling. Workpieces with a larger weight slide into the quenching tank at a faster speed, and it is easy to have situations such as bumping or jamming, resulting in workpiece damage, quenching tank damage, and affecting production efficiency. In addition, when the workpiece is quenched in the existing quenching tank, it is easy to cause an unsatisfactory quenching effect due to uneven heat distribution in the quenching medium; the increase in temperature of the quenching medium after long-term use will have an adverse effect on the quenching treatment effect; the oxide scale falling into the quenching tank will block the circulation system of the quenching tank.

[0003] A track link is a structure used to connect and transmit power in the crawlers of construction machinery such as excavators and bulldozers. It bears a large load and has a relatively large self-weight. In the processing process of track links, higher requirements are placed on their structural performance. The track links slide into the quenching tank at a faster speed and are prone to damage; the surface of the track links has many concave and convex surfaces, and it is even more likely to have a situation where the temperature of the quenching medium around the workpiece is uneven.

[0004] In summary, there is a need in the art to improve the quenching device for track links to prevent damage to the track links when they slide into the tank body, and at the same time improve the quenching treatment effect on the track links. Summary of the Utility Model

[0016] As Figure 2 shown is the top view of a quenching device for a track link of the present invention. Detailed implementation manners

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] As Figure 1 and Figure 2 shown, a quenching device for a track link of the present application includes a quenching tank 1, a falling channel 2, an anti-collision component 3, a high-pressure spraying component 4, a stirring component 5, a hoist 6, and a circulation component 7. The quenching tank 1 has a tank body 10 for containing a quenching medium. The falling channel 2, the high-pressure spraying component 4, and the hoist 6 are arranged in sequence. The falling channel 2 obliquely extends into the tank body 10. The anti-collision component 3 is combined and installed with the falling channel 2, and the opening and closing state of the falling channel 2 is controlled by the anti-collision component 3. The high-pressure spraying component 4 is arranged inside the tank body 10, and the high-pressure spraying component 4 is docked with the bottom end of the falling channel 2. The stirring component 5 is arranged inside the tank body 10, and the stirring component 5 is docked with the high-pressure spraying component 4. The hoist 6 obliquely extends out of the tank body 10, and the bottom end of the hoist 6 is docked with the high-pressure spraying component 4. The circulation component 7 is combined and installed with the quenching tank 1, and the circulation component 7 is communicated with the tank body 10.

[0019] The quenching device for the track link can buffer the track link when it falls through the anti-collision component 3, preventing damage caused by collision when the track link falls rapidly. The high-pressure spraying component 4 and the stirring component 5 are arranged inside the quenching device for the track link, which can improve the temperature uniformity of the quenching medium in the tank body 10 and effectively improve the quenching treatment effect and efficiency of the track link.

[0020] Specifically, the anti-collision component 3 includes a baffle that slides up and down under control. When the baffle moves downward, it blocks the falling channel 2 to block and buffer the falling track links. Then, when the baffle moves upward, the track links slide downward into the quenching medium in the tank 10 at a slower speed.

[0021] The high-pressure spraying component 4 has a structure that sprays simultaneously from above and below. The track links that slide into the tank 10 are located in the middle of the high-pressure spraying component 4. The track links are sprayed with the quenching medium simultaneously from above and below. By spraying from the upper part, the cooling speed is increased, and the hardenability of the track links is improved. By spraying from the lower part, the situation of yin-yang surfaces on the track links after quenching is prevented.

[0022] Preferably, two stirring components 5 are symmetrically arranged on the side of the high-pressure spraying component 4. The stirring component 4 has a liquid outlet spraying port facing the high-pressure spraying component 4, and sprays the quenching medium to the side of the track links, increasing the flow rate of the quenching medium around the track links, improving the hardenability of the track links, and at the same time improving the temperature uniformity of the quenching medium in the tank 10 and improving the quality of the quenching treatment.

[0023] The circulation component 7 includes a circulation pump. A filter screen is arranged at the liquid inlet of the circulation component 7 to prevent the scale in the tank 10 from entering the circulation component 7 of the quenching medium and causing blockage. Further, a cooling component is combined in the circulation component 7 to keep the temperature of the quenching medium in the tank 10 in line with the process requirements and ensure the effect of the quenching treatment.
