[0002] The quenching process of steel is to first heat the steel to above the critical temperature and keep it at this temperature for a period of time so that the steel is fully or partially austenitized. After the insulation process is completed, the steel is placed in a certain environment to allow the steel to be rapidly cooled at a rate greater than the critical cooling rate, causing a significant change in the performance of the steel, that is, a martensitic transformation. The purpose of quenching is to significantly improve the strength, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the different use requirements of various mechanical parts and tools.

[0037] A water tank 3, the water tank 3 is fixedly installed at the bottom of the housing 1, a water pump 33 is fixedly installed at the output end of the water tank 3, a water pipe 34 is fixedly installed at the output end of the water pump 33, and the output end of the water pipe 34 is fixedly installed at one side of the housing 1;

[0038] A water collecting frame 4, wherein the water collecting frame 4 is fixedly mounted on the bottom of the other side of the housing 1;

[0039] A filter assembly 5, wherein the filter assembly 5 is fixedly mounted at the bottom of the water collecting frame 4, and the filter assembly 5 comprises a first valve 51, a delivery pipe 52, a threaded ring 53, a storage pipe 54, a second valve 55, a filter pipe 56 and a filter screen 57. The first valve 51 is fixedly mounted at the bottom of the water collecting frame 4, the delivery pipe 52 is fixedly mounted at the top of the first valve 51, the threaded ring 53 is threadedly connected to the bottom of the outer side of the delivery pipe 52, the storage pipe 54 is fixedly mounted at the bottom of the threaded ring 53, the second valve 55 is fixedly mounted at the bottom of the storage pipe 54, one end of the filter pipe 56 is fixedly mounted inside the side of the delivery pipe 52, the filter screen 57 is fixedly mounted at one end of the inner side of the filter pipe 56, and the other end of the filter pipe 56 is fixedly mounted on the side of the water tank 3.

[0040] By installing a protective frame 11 on the top of the housing 1, splashing of the quenching solution can be reduced;

[0041] When the material storage tube 54 needs to be disassembled and cleaned, the user can close the first valve 51 and then rotate the material storage tube 54 so that the thread ring 53 is threadedly connected to the bottom of the outer side of the delivery tube 52, thereby disassembling and cleaning the material storage tube 54.

[0042] Support legs 12 are fixedly mounted around the bottom of the housing 1 .

[0043] Slide rods 24 are slidably connected to the interior of both ends of the support plate 22. The top of the slide rod 24 is fixedly installed on the bottom of the electric telescopic rod 21. The internal thread of the bottom of the slide rod 24 is connected to a positioning screw 25. The outer side of the positioning screw 25 is sleeved with a baffle 26.

[0045] A plurality of through holes are formed inside the supporting plate 22 and the surrounding plate 23 .

[0046] By opening a plurality of through holes, the liquid can flow smoothly inside the housing 1 during use, thereby increasing the quenching effect.

[0047] The working principle of the automatic quenching equipment for steel casting surface provided by the present invention is as follows:

[0048] When in use, the user places the steel casting to be quenched on the support plate 22, and then starts the electric telescopic rod 21 to extend the electric telescopic rod 21, driving the support plate 22 to move downward, so that the support plate 22 drives the steel casting to move to the inner side of the shell 1, and contacts the liquid inside the shell 1, so as to quench the steel casting.

[0049] When quenching is performed, the water pump 33 can extract the liquid inside the water tank 3 and then transport it to the inside of the outer shell 1, thereby circulating the liquid used for quenching inside the outer shell 1, and at the same time, the liquid inside the outer shell 1 will enter the inside of the filter assembly 5 through the water collecting frame 4, and then the filter 57 will filter the impurities in the discharged liquid, and then the filtered liquid will re-enter the inner side of the water tank 3, and the impurities will be accumulated on the inner side of the storage pipe 54. When it is necessary to clean the impurities inside the storage pipe 54, the user can open the second valve 55 to discharge the impurities stored in the storage pipe 54.

[0050] Compared with the related art, the automatic quenching equipment for steel casting surface provided by the present invention has the following advantages:

[0051] Beneficial effects:

[0052] The housing 1, the protection frame 11, the mounting frame 2, the electric telescopic rod 21, the support plate 22, the enclosure 23 and the slide rod 24 cooperate with each other. When in use, the steel casting to be quenched is placed on the support plate 22, and then the user moves away from the housing 1. Then, the electric telescopic rod 21 is extended, so that the support plate 22 drives the steel casting to move to the inner side of the housing 1, so that the liquid inside the housing 1 has the effect of quenching the steel casting, which can avoid the user holding the steel casting for quenching, thereby increasing safety;

[0053] In addition, by cooperating with each other, structures such as the filter component 5, the water tank 3 and the water pump 33, when in use, the liquid after the quenching can enter the inner side of the filter component 5, and then the liquid is filtered, and then transported to the inner side of the water tank 3 for subsequent use. After filtering, the user only needs to open the second valve 55 to process the collected impurities, which is convenient and quick to operate.

[0054] Second embodiment

[0055] Please refer to Figure 6 , Figure 7 and Figure 8Based on the automatic surface quenching equipment for steel castings provided in the first embodiment of the present application, the second embodiment of the present application proposes another automatic surface quenching equipment for steel castings. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0056] Specifically, the difference of the automatic surface quenching equipment for steel castings provided in the second embodiment of the present application is that, in the automatic surface quenching equipment for steel castings, semiconductor refrigeration plates 63 are fixedly installed on the front and back sides of the inner side of the water tank 3, and multiple heat sinks 64 are fixedly installed on the sides of the two semiconductor refrigeration plates 63, and the multiple heat sinks 64 are respectively fixedly installed on the front and back sides of the water tank 3.

[0060] By covering the outer side of the plurality of heat sinks 64 with a fixing frame 6, the heat sink 64 can be protected when in use.

[0061] The semiconductor cooling sheet 63 is the core component of semiconductor cooling. It uses the Peltier effect of semiconductor materials. When current passes through a couple composed of different semiconductor materials, heat can be absorbed and released at both ends of the couple, thereby achieving the purpose of cooling.

[0062] The heat sink 64 is mainly used to dissipate the heat generated by the hot end of the semiconductor cooling plate. During the semiconductor cooling process, one end of the semiconductor cooling plate 63 absorbs heat to achieve cooling, while the other end releases heat. The heat sink increases the contact area with the air and improves the heat dissipation efficiency, so that the heat at the hot end is quickly dissipated to the surrounding environment;

[0063] The fan 62 assists the heat sink 64 in dissipating heat by accelerating the air flow to take away the heat on the heat sink 64. The speed and air volume of the fan 62 can be adjusted according to the cooling demand to ensure a good heat dissipation effect.

[0064] The working principle of the automatic quenching equipment for steel casting surface provided by the present invention is as follows:

[0065] During use, when the temperature inside the water tank 3 is high, the user can start the semiconductor refrigeration sheet 63 and the fan 62, so that the fan 62 blows air to the heat sink 64, thereby dissipating the heat of the heat sink 64 and allowing the semiconductor refrigeration sheet 63 to cool the liquid in the water tank 3.

[0066] Compared with the related art, the automatic quenching equipment for steel casting surface provided by the present invention has the following advantages:

[0067] Beneficial effects:

[0068] By cooperating with each other, structures such as the semiconductor refrigeration sheet 63, the heat sink 64 and the fan 62, when in use, the fan 62 can blow air to the heat sink 64, so that the semiconductor refrigeration sheet 63 can cool the liquid in the water tank 3, thereby increasing the quenching effect on the steel casting.

[0074] When in use, the user can observe the inner side of the shell 1 through the high-temperature glass 71, and after the observation, the user can rotate the door body 72, so that the door body 72 rotates on the front of the installation frame 7 until the door body 72 rotates to the front of the high-temperature glass 71, thereby protecting the high-temperature glass 71.
