The driving mechanism 7 is drivably connected to the loading tray 3, and is used to drive the loading tray 3 to move in the vertical direction. When in use, an appropriate amount of quenching liquid is injected into the quenching tank 2, and the driving mechanism 7 is started to lift the loading tray 3, and the steel balls to be quenched are transferred to the loading tank 31 using professional handling equipment, and then the driving mechanism 7 is started to lower the loading tray 3, and the steel balls are immersed in the quenching liquid for quenching. The quenching liquid penetrates through the liquid permeable holes 32. The loading tray 3 can load multiple steel balls at the same time, and different steel balls are independent of each other, thereby improving the safety and efficiency of quenching.

[0041] Optionally, by Figure 1 As shown, in this embodiment, it also includes: an auxiliary lifting plate 4, a main lifting plate 6 and an adjustment mechanism 8. The loading plate 3 is fixed to the bottom of the auxiliary lifting plate 4 by a fixing rod 5, and the main lifting plate 6 is located directly above the auxiliary lifting plate 4. The adjustment mechanism 8 is installed on the main lifting plate 6 to adjust the height of the auxiliary lifting plate 4. The height of the loading plate 3 can be further adjusted by the adjustment mechanism 8 to ensure that the steel balls can be reliably immersed in the quenching liquid during processing.

[0042] Optionally, by Figure 1 As shown, in this embodiment, the driving mechanism 7 includes: a vertical plate 71, a top plate 72, a threaded column 73 and a No. 1 driving motor 74. The vertical plate 71 is fixed on the frame 1, the top plate 72 is fixed on the top of the vertical plate 71, the threaded column 73 is rotatably installed between the frame 1 and the top plate 72, and the threaded column 73 passes through the main lifting plate 6 and is connected to the main lifting plate 6 by threaded screwing. The No. 1 driving motor 74 is fixed on the top plate 72 to drive the threaded column 73 to rotate. The No. 1 driving motor 74 is started to drive the threaded column 73 to rotate. Under the action of the threaded screwing, the main lifting plate 6 drives the auxiliary lifting plate 4 to move in the vertical direction, and then drives the loading plate 3 to move in the vertical direction.

[0043] Optionally, by Figure 1 As shown, in this embodiment, the adjustment mechanism 8 includes: a vertical cylinder 81, the vertical cylinder 81 is fixed on the main lifting plate 6, and the piston rod of the vertical cylinder 81 passes through the main lifting plate 6 and is fixedly connected to the auxiliary lifting plate 4. The vertical cylinder 81 is started, and the height of the loading plate 3 is further adjusted by the vertical cylinder 81 to ensure that the steel balls can be reliably immersed in the quenching liquid during processing.

[0044] Preferably, by Figure 1 As shown, in this embodiment, it also includes: a No. 1 guide column 75, which is fixed between the frame 1 and the top plate 72 and passes through the main lifting plate 6, and is used to guide the main lifting plate 6 to improve the stability of the main lifting plate 6.

[0045] Preferably, by Figure 1 As shown, in this embodiment, it also includes: a second guide column 82, which is fixed on the auxiliary lifting plate 4 and passes through the main lifting plate 6, and is used to guide the auxiliary lifting plate 4 to improve the stability of the auxiliary lifting plate 4.

[0046] Preferably, by Figure 1 As shown, in this embodiment, an injection port 21 and a discharge port 22 are respectively fixed at the top and bottom ends of the outer side surface of the quenching tank 2. When in use, the injection port 21 and the discharge port 22 are respectively connected to a water pump, and the quenching liquid is injected into the quenching tank 2 through the injection port 21, and the used quenching liquid is drawn out through the discharge port 22 to facilitate replacement of new quenching liquid.

[0047] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, a stirring mechanism 9 is also included. The stirring mechanism 9 is located in the quenching tank 2, and the stirring mechanism 9 includes: a rotating column 91, a stirring rod 92 and a second driving motor 93. The rotating column 91 is rotatably installed in the quenching tank 2, and a plurality of stirring rods 92 are evenly fixed on the rotating column 91. The second driving motor 93 is fixed on the bottom surface of the frame 1 to drive the rotating column 91 to rotate. Because the new quenching liquid can generally be reused many times, during subsequent use, the quenching liquid will absorb the temperature of the steel ball. At this time, the temperature of the quenching liquid is uneven. Therefore, before the next quenching, the No. 2 driving motor 93 is started to drive the rotating column 91 to rotate, so that the plurality of stirring rods 92 rotate to stir the quenching liquid, so that the temperature of the quenching liquid is more uniform.

[0052] After quenching is completed, the first drive motor 74 is started to drive the threaded column 73 to rotate in the opposite direction, so that the loading plate 3 moves upward, the steel balls are separated from the quenching liquid, and the material can be unloaded;

[0053] Before the next quenching, the second drive motor 93 is started to drive the rotating column 91 to rotate, so that the multiple stirring rods 92 rotate to stir the quenching liquid, so that the temperature of the quenching liquid is more uniform;

[0054] The loading plate 3 of the utility model can load a plurality of steel balls at the same time, and different steel balls are independent of each other, thereby improving the safety and efficiency of quenching.
