[0002] Quenching is a heat treatment process method that heats steel to above the critical temperature, keeps it warm for a certain period of time, and then cools it at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite. Quenching is the most widely used process method in steel heat treatment. At present, in the manufacture of bearing steel balls, in order to improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the bearing balls, it is necessary to use a quenching tank to carry out the quenching activity of the bearing steel balls;

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 As shown:

[0028] A bearing ball quenching device comprises a workbench 1 and a mounting box 2 symmetrically fixedly connected to the bottom surface of the workbench 1.

[0029] In this implementation scheme: the existing disclosure (announcement) number: CN216107083U discloses a bearing ball quenching device; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the above-mentioned design is in use, as the number of processed steel balls increases, the temperature of the quenching liquid will gradually increase with the quenching process, and the above-mentioned device is not provided with a cooling device, so that the quenching effect of the quenching liquid on the balls is reduced, and after the quenching of the balls is completed, the balls need to be salvaged from the quenching liquid, which is inconvenient to collect and reduces the production efficiency of the balls." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a circulation component 3 and a feeding component 4 are added to the application document.

[0030] More specifically:

[0031] like Figure 1-Figure 4 As shown:

[0032] In combination with the above content, the circulation component 3 includes a quenching chamber 38 opened inside the workbench 1, and a plurality of groups of conveying rails 33 with a semicircular structure are fixedly connected inside the workbench 1. A circulation pipe 31 with a U-shaped structure is fixedly connected to the bottom surface of the workbench 1, and one end of the circulation pipe 31 is connected to the quenching chamber 38. A plurality of groups of heat dissipating fins 34 are fixedly connected to one side of the surface of the circulation pipe 31, and one end of the heat dissipating fins 34 is located inside the circulation pipe 31, and the other end of the heat dissipating fins 34 is located outside the circulation pipe 31. A circulation pump 32 is installed on the side of the workbench 1, and the output end and input end of the circulation pump 32 are respectively connected to the circulation pipe 31 and the quenching chamber 38.

[0033] In this embodiment: when the bearing ball quenching device is in use, the balls enter the quenching chamber 38 along the conveying rail 33, so that the balls are immersed in the quenching liquid, and the balls are cooled by the quenching liquid. At the same time, starting the circulation pump 32 can drive the quenching liquid in the quenching chamber 38 to flow, thereby improving the cooling effect on the balls. Then, the quenching liquid that absorbs heat will be transported to the inside of the circulation pipe 31, and the heat will be dissipated through multiple sets of heat dissipating fins 34, thereby cooling the quenching liquid and realizing the recycling of the quenching liquid.

[0034] Going further:

[0035] like Figure 1-Figure 4 As shown:

[0036] In order to improve the cooling effect on the quenching liquid, in an optional embodiment: a plurality of groups of fans 36 are installed inside the installation box 2; a dustproof net 35 is installed on one side of the installation box 2 close to the fan 36 by bolts; two groups of guide blocks 39 with a trapezoidal structure are fixedly connected to the upper surface of the workbench 1; a plurality of groups of dividing plates 37 are fixedly connected to the upper surface of the workbench 1, and the position of the dividing plates 37 corresponds to the conveying rail 33.

[0037] In this embodiment: when the heat dissipation fins 34 are being used for heat dissipation, starting the fan 36 can speed up the air flow on one side of the heat dissipation fins 34, thereby improving the cooling effect of the heat dissipation fins 34 on the quenching liquid. The dustproof net 35 can prevent external dust from entering one side of the heat dissipation fins 34 and affecting the heat dissipation effect of the heat dissipation fins 34. The guide block 39 can guide the balls, and the dividing plate 37 can separate and transport multiple groups of balls, thereby improving the quenching effect on the balls.

[0038] More specifically:

[0039] like Figure 1-Figure 4 As shown:

[0040] In combination with the above content, a feeding assembly 4 is provided on the surface of the workbench 1, and the feeding assembly 4 includes a rotating roller 42 rotatably connected to the workbench 1, and a plurality of groups of push plates 41 in a circular array are fixedly connected to the surface of the rotating roller 42, and the position of the push plates 41 corresponds to the conveying rail 33, and a synchronous wheel 2 45 is fixedly connected to one end of the rotating roller 42, and a motor 44 is installed on the side of the surface of the workbench 1 close to the synchronous wheel 2 45, and a synchronous wheel 1 43 is fixedly connected to the output end of the motor 44, and the synchronous wheel 1 43 and the synchronous wheel 2 45 are connected by a synchronous belt; a plurality of groups of hole grooves are opened on the surface of the push plate 41.

[0041] In this embodiment: when quenching the bearing balls, the guide block 39 transports the balls and separates the balls through the dividing plate 37, then the motor 44 is started to drive the synchronous wheel 1 43 to rotate, and the synchronous wheel 1 43 will drive the synchronous wheel 2 45 to rotate through the synchronous belt, and then drive the rotating roller 42 to rotate, so that multiple groups of push plates 41 push each ball separately to avoid the balls being close to each other and affecting the cooling effect of the balls, thereby improving the cooling effect of the quenching liquid on the balls. As the rotating roller 42 rotates, the push plate 41 will transport the cooled balls to the side of the guide block 39 for unloading, thereby completing the quenching of the balls.

[0042] It should be noted that the motor 44 , the circulation pump 32 and the fan 36 are all electrically connected to an external power source through wires.

[0043] Working principle: When quenching the bearing balls, the guide block 39 transports the balls and separates the balls through the dividing plate 37, then the motor 44 is started to drive the synchronous wheel 1 43 to rotate, and the synchronous wheel 1 43 will drive the synchronous wheel 2 45 to rotate through the synchronous belt, and then drive the rotating roller 42 to rotate, so that multiple groups of push plates 41 push each ball separately to avoid the balls from sticking to each other and affecting the cooling effect of the balls, thereby improving the cooling effect of the quenching liquid on the balls. As the rotating roller 42 rotates, the push plate 41 will transport the cooled balls to the side of the guide block 39 for unloading, completing the quenching of the balls. Fire, during the ball cooling process, starting the circulation pump 32 can drive the quenching liquid in the quenching chamber 38 to circulate, thereby improving the cooling effect on the balls, and then the quenching liquid that absorbs heat will be transported to the inside of the circulation pipe 31, and the heat will be dissipated through multiple groups of heat dissipation fins 34, thereby cooling the quenching liquid and recycling the quenching liquid, and starting the fan 36 can accelerate the air flow on one side of the heat dissipation fin 34, thereby improving the cooling effect of the heat dissipation fin 34 on the quenching liquid, and the dustproof net 35 can prevent external dust from entering one side of the heat dissipation fin 34 and affecting the heat dissipation effect of the heat dissipation fin 34.

[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
