DETAILED DESCRIPTION

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

There is a gap between the transmission belt 20 and the flow partition 11 to avoid interfering with the operation of the transmission belt 20. The flow partition 11 divides the circulation channel into a bead discharge channel 102 and a reflux channel 103. The bead discharge channel 102 is on the upper side of the reflux channel 103. The bead inlet 101 and the bead discharge channel 102 are connected. After the steel balls enter the bead inlet 101 of the quenching pool 10, they will be taken out of the quenching pool by the transmission belt 20 through the bead discharge channel 102. The reflux block 12 divides the bead inlet 101 into a narrow channel 104, and the end of the reflux channel 103 is connected to the narrow channel 104. A part of the quenching liquid in the reflux channel 103 will return to the bead inlet 101 through the narrow channel 104, so that the quenching liquid in the bead inlet 101 participates in the circulation; the top of the conveyor belt 20 is higher than the top of the quenching pool 10 to facilitate the steel balls to leave the quenching pool 10; the top of the flow partition 11 is lower than the liquid level of the quenching pool 10, Figure 2 The mark a in the figure is a liquid level height that can be used as a reference, which can facilitate the communication between the bead discharge channel 102 and the reflux channel 103.

[0020] In one embodiment of the present application, preferably, Figure 1 , Figure 2 As shown, the bead inlet 101 and the narrow channel 104 are connected by a partition 13, and a through hole for reflux is provided on the partition 13; on the one hand, the partition 13 prevents the steel balls from falling into the narrow channel 104, and on the other hand, the refluxed quenching liquid can be more fully exchanged and circulated with the quenching liquid in the bead inlet 101 through the through hole; the partition 13 is inclined to facilitate the steel balls to roll toward the conveyor belt 20.

[0021] In one embodiment of the present application, preferably, Figure 1 , Figure 2As shown, the length of the surface of the reflux block 12 facing the drive belt 20 in the direction of movement of the drive belt 20 is greater than the distance between any two paddles 21; and when the drive belt 20 is running, there are always two paddles in conflict with the reflux block 12; in this way, when the quenching liquid is at the end of the reflux channel 103, a part of it is carried by the two paddles 21 to pass through the lower side of the reflux block 12, while the other part is driven and forced to pass through the narrow channel 104, so that the circulation of the quenching liquid is more complete.

[0022] In one embodiment of the present application, preferably, Figure 1 , Figure 2 As shown, the surface of the reflux block 12 facing the bead inlet 101 is inclined at a certain angle toward the bead discharge channel 102 to facilitate the balls to roll onto the transmission belt 20; the surface of the reflux block 12 facing the narrow channel 104 is vertically arranged to keep the overall width of the narrow channel 104 consistent, which is convenient for reflux of quenching liquid.

[0023] In one embodiment of the present application, preferably, Figures 1 to 3 As shown, a cooling liquid channel 105 is further provided in the quenching pool 10 for cooling the liquid in the reflux channel 103 .

[0024] In one embodiment of the present application, preferably, Figures 1 to 3 As shown, a filter plate 111 parallel to the flow partition 11 is fixedly disposed at the top of the flow partition 11. A dirt storage cavity 1101 is also disposed at the top of the flow partition 11. The top of the filter plate 111 is higher than the liquid level.

[0025] In one embodiment of the present application, Figure 1 , Figure 2 As shown, the distance between the top of the paddle plate 21 and the surface of the circulation channel it faces is always consistent, so that the paddle plate 21 can evenly move the quenching liquid; preferably, the distance is smaller than the height of the paddle plate 21 and larger than half the height of the paddle plate 21; in this way, when the paddle plate 21 drives the quenching liquid to circulate, on the one hand, it can achieve a sufficient driving effect, and on the other hand, it can increase the amount of quenching liquid entering the narrow channel 104, so that the quenching liquid in the bead inlet 101 can circulate more fully.

[0026] The wheel hub bearing steel ball processing quenching and cooling device provided by the utility model is cooled by the quenching liquid after the steel balls fall into the bead inlet 101, and part of the steel balls fall directly onto the transmission belt 20, and part of the steel balls fall onto the reflux block 12 and the partition plate 13 and then roll onto the transmission belt 20, and then the cooled steel balls are driven by the paddle plate 21 of the conveyor belt 20 to leave the quenching pool 10. At the same time, in the quenching pool 10, the quenching liquid is driven by the paddle plate 21 on the transmission belt 20 to circulate, and the hotter quenching liquid at the bead inlet 101 will be driven by the paddle plate 21, and after passing through the bead discharge channel 102, the reflux channel 103 and the narrow channel 104, it returns to the bead inlet 101 to cool the steel balls, so as to achieve the overall circulation of the quenching liquid in the quenching pool, and the circulation can keep the temperature of the quenching liquid as uniform as possible, so as to achieve a better quenching effect.
