Embodiment 1

[0018] Such as figure 1 , figure 2 As shown, a cooling device for an automobile spindle includes a cooling tower 1, a cooling oil pool 2, and a cooling water pool 3. The cooling oil pool 2 includes a cooling oil pool body 201 and a cooling channel 202 arranged on the cooling oil pool body 201. The cooling Channel 202 is a spiral channel, the left end of cooling channel 202 communicates with cooling tower 1 through water inlet pipe 203, the right end of cooling channel 202 communicates with cooling water pool 3, cooling water pool 3 communicates with cooling tower 1, cooling tower 1, cooling channel 202 and cooling water pool 3 The levels of the three are lowered successively, and a water pump 4 is installed on the connecting pipe between the cooling water pool 3 and the cooling tower 1.

[0019] During specific work, the cooling water enters the cooling channel 202 from the cooling tower 1, and after cooling the cooling oil pool 2, it flows into the cooling water pool 3 to h...

Embodiment 2

[0021] The difference between this scheme and Embodiment 1 is that the levels of the cooling passage 202, the cooling water pool 3 and the cooling tower 1 are successively lowered, and the water pump 4 is installed on the water inlet pipe 203 between the cooling tower 1 and the cooling passage 202 . During specific operation, the cooling water is pumped into the cooling channel 202 by the water pump 4, and the cooling operation can be performed.

Abstract

The invention belongs to heat treatment cooling systems, and particularly discloses a cooling device of an automobile central spindle. The cooling device comprises a cooling oil pool and a cooling water pool. The cooling device further comprises a cooling tower. A cooling channel is arranged in the wall of the cooling oil pool. A water inlet of the cooling channel is communicated with the cooling tower, and a water outlet of the cooling channel is communicated with the cooling water pool. The cooling water pool is communicated with the cooling tower, and cooling water circulates in the cooling tower, the cooling channel and the cooling water pool. Compared with a traditional cooling device, no fan needs to be additionally arranged, and compared with air cooling, the cooling effect of water cooling is better. Meanwhile, due to the fact that the temperature of the water is about 50 DEG C during the tempering stage and larger than the temperature of cooling oil, the cooling water can firstly cool the cooling oil and then take away heat of the cooling oil, the cooling oil is exactly adopted as cooling media during the tempering stage after temperature rises, and no cooling medium needs to be additionally arranged.

Description

technical field [0001] The invention belongs to a heat treatment cooling system, in particular to an automobile core shaft cooling device. Background technique [0002] The car mandrel is an important part in the car, and its quality is related to the overall quality and safety factor of the car. In order to ensure the quality of the car mandrel, the car mandrel is usually heat treated before processing, mainly the car mandrel is quenched and tempered. The temperature of the automobile mandrel in the quenching operation is usually around 900°C, which is cooled by cooling oil, and the temperature of the cooling oil is about 40°C; the temperature of the car mandrel in the tempering operation is usually around 600°C, and the cooling water The temperature is around 50°C. In order to ensure the heat treatment quality of the automobile spindle, the temperature of the cooling oil and cooling water is not easy to fluctuate too much, so the cooling oil and cooling water must be coo...
