[0001] This application relates to the technical field of quenching of mechanical parts, and particularly relates to a quenching device for mechanical parts. Background Technique
[0002] Quenching is a heat treatment process. The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), hold it for a period of time to make all or part of it austenitized, and then quickly cool it at a cooling rate greater than the critical cooling rate to below Ms (or isothermally near Ms) for martensite (or bainite) transformation heat treatment process.
[0003] However, in actual applications, when most existing mechanical parts are quenched using quenching oil, impurities such as scale and rust on the surface of the mechanical parts will also enter the quenching oil during the quenching process, forming slag. Over time, as the slag accumulates continuously, it will lead to a continuous decrease in the cooling effect and service life of the quenching oil, and further reduce the quenching quality of the parts, which is not conducive to popularization and use.
[0004] Therefore, those skilled in the art have provided a quenching device for mechanical parts to solve the problems raised in the above background technique. Utility Model Content

Over time, as the slag accumulates continuously, it will lead to a continuous decrease in the cooling effect and service life of the quenching oil, and further reduce the quenching quality of the parts, which is not conducive to popularization and use, this application provides a quenching device for mechanical parts.
[0006] A quenching device for mechanical parts provided by this application adopts the following technical solution: It includes a quenching tank. The top of the left and right sides of the quenching tank is rotatably connected with a first transmission plate. The bottom side of each of the two first transmission plates is rotatably connected with a second transmission plate.

[0007] Preferably, springs are fixedly connected to the left and right sides of the quenching tank. The top ends of the two springs are fixedly connected with square plates. The two square plates are respectively slidably connected to the left and right sides of the quenching tank. The top sides of the two square plates and the bottom sides of the two first transmission plates are fixedly connected with pull rings.

[0011] In summary, this application has the following beneficial technical effects:
[0012] 1. By setting up the filter plate, the parts that need to be quenched are placed on the filter plate. The filter plate will move downward due to the weight of the parts. At this time, the placed parts will gradually be immersed in the quenching oil for quenching. When the parts are quenched and taken out, the filter plate will be moved upward and reset. At this time, the filter plate can filter out the oxide scale, rust and other impurities that fall from the quenching oil and drive the oxide scale, rust and other impurities to move upward and out of the quenching oil, making it convenient for workers to clean. At the same time, after cleaning impurities such as oxide scale and rust, the cooling effect of the quenching oil can be effectively ensured, the service life can be improved, the quenching quality of the product can be guaranteed, and it is conducive to promotion and use.
[0013] 2. By setting a spring, the filter plate moves downward under the influence of the weight of the parts. At this time, the first transmission plate and the second transmission plate will also flip over synchronously. When the parts are quenched and taken out, the rebound force of the spring drives the square plate to move downward and reset. The movement of the square plate cooperates with the pull ring and the wire rope to drive the first transmission plate to flip and reset. After the reset, the first transmission plate pulls the second transmission plate upward, and the second transmission plate drives the filter plate to move upward and reset, so that it is convenient for workers to clean the oxide scale, rust and other impurities remaining on the filter plate, effectively improving the convenience of use.

[0018] The following will be combined with the Figures 1-3 The technical solution of the present invention is clearly and completely described. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0019] The present application discloses a mechanical parts quenching device, referring to Figures 1-3 The bottom of the two second transmission plates 3 are rotatably connected to the same filter plate 4, and the interior of the quenching box 1 is filled with quenching oil. By setting the filter plate 4, the parts to be quenched are placed on the filter plate 4. The filter plate 4 will move downward under the influence of the weight of the parts. At this time, the placed parts will gradually be immersed in the quenching oil for quenching. When the parts are quenched and taken out, the filter plate 4 will be moved upward and reset. At this time, the filter plate 4 can filter out the oxide scale, rust and other impurities that fall from the quenching oil and drive the oxide scale, rust and other impurities to move upward and out of the quenching oil, thereby facilitating the workers to clean them. At the same time, after the oxide scale, rust and other impurities are cleaned, the cooling effect of the quenching oil can be effectively ensured, the service life can be improved, the quenching quality of the product can be guaranteed, and it is conducive to popularization and use.
[0020] When the filter plate 4 is in the state of being moved down, the filter plate 4 of Fig. 1 is in the state of being moved down, and the filter plate 4 of Fig. 2 is in the state of being moved down.
[0021] In the present application, the filter plate 4 is formed by a frame and foam filling; by setting the filter plate 4 to be formed by a frame and foam filling, the filter plate 4 itself has a certain buoyancy, so that the filter plate 4 can use its own buoyancy to speed up the reset speed while filtering, so as to facilitate subsequent use, thereby improving efficiency and saving time.
[0022] In this application, vertical grooves are provided on the inner walls of the left and right sides and the rear inner wall of the quenching tank 1. Vertical blocks 9 are slidably connected to the inner walls of the three vertical grooves. The three vertical blocks 9 are fixedly connected to the left and right sides and the rear side of the filter plate 4 respectively. By providing the vertical grooves and the vertical blocks 9, when the filter plate 4 moves up or down, the vertical grooves and the vertical blocks 9 cooperate with each other, enabling the filter plate 4 to move vertically in a horizontal state and preventing deviation, which may affect the filtering effect.
[0023] In this application, an observation hole is provided on the front side of the quenching tank 1, and a transparent glass 10 is fixedly installed on the inner wall of the observation hole. By providing the transparent glass 10, the quenching oil inside the quenching tank 1 can be observed by utilizing the light transmission of the transparent glass 10, facilitating timely replenishment or replacement of the quenching oil to ensure the effect of the quenching operation.
[0024] The standard parts used in this utility model can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the attached drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art. Additionally, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
[0025] The implementation principle of a mechanical parts quenching equipment in an embodiment of the present application is as follows: when in use, the parts to be quenched are placed on the filter plate 4, and the filter plate 4 will move downward due to the influence of the weight of the parts. At this time, the placed parts will gradually be immersed in the quenching oil for quenching operation. When the parts are quenched and taken out, the filter plate 4 is moved upward and reset. At this time, the filter plate 4 can filter out impurities such as oxide scale and rust that fall from the quenching oil and drive impurities such as oxide scale and rust to move upward and out of the quenching oil, thereby facilitating cleaning by workers. At the same time, after the oxide scale, rust and other impurities are cleaned, the cooling effect of the quenching oil can be effectively ensured, the service life is improved, the quenching quality of the product is guaranteed, and it is conducive to popularization and use. The filter plate 4 is affected by the weight of the parts and moves downward. At this time, the first transmission plate 2 and the second transmission plate 3 will also flip synchronously. When the parts are quenched and taken out, the rebound force of the spring 5 drives the square plate 6 to move downward. After the filter plate 4 is reset, the square plate 6 moves and cooperates with the pull ring 7 and the wire rope 8 to drive the first transmission plate 2 to flip and reset. After the reset, the first transmission plate 2 pulls the second transmission plate 3 to move upward, and the second transmission plate 3 drives the filter plate 4 to move upward and reset, so as to facilitate the workers to clean the oxide scale, rust and other impurities remaining on the filter plate 4, effectively improving the convenience of use. The filter plate 4 is made of a frame and foam cotton filling, so that the filter plate 4 itself has a certain buoyancy, so that it can use its own buoyancy to speed up the reset speed while filtering, so as to facilitate subsequent continued use, thereby improving efficiency and saving time. When the filter plate 4 moves up or down, the vertical groove and the vertical block 9 cooperate with each other to make the filter plate 4 horizontal and maintain vertical movement to avoid deviation affecting the filtering effect. The light transmittance of the transparent glass 10 can be used to observe the quenching oil inside the quenching box 1, so that the quenching oil can be replenished or replaced in time to ensure the quenching operation effect.
