The automatic cooling device also includes:

[0031] The ventilation bracket 4 is rotatably mounted in the bellows body 1. The ventilation bracket 4 is through-set in the transverse and longitudinal directions. The side end of the ventilation bracket 4 is also circumferentially provided with a plurality of mounting grooves 5;

[0032] A positioning bracket 6 for positioning and placing the steel sample, wherein the positioning bracket 6 is provided in a plurality and is rotatably arranged in the mounting groove 5 via a rotating shaft 7;

[0033] A spring 8, one end of the spring 8 is fixedly connected to the lower portion of the positioning bracket 6, and the other end of the spring 8 abuts against the inner surface of the mounting groove 5;

[0034] A driving mechanism is used to drive the ventilation bracket 4 to rotate, and the driving mechanism is installed on the bellows body 1.

[0035] In this embodiment, the driving mechanism includes:

[0036] Cylinder 9, cylinder 9 is mounted on the outer side of bellows body 1 through mounting frame 10;

[0037] The gear ring 11 is fixedly mounted on the lower part of the ventilation bracket 4;

[0038] The rack 12 is slidably disposed in the bellows body 1 through a guide seat 13 , and the rack 12 is meshed with the gear ring 11 .

[0039] In this embodiment, when in use, the high-temperature steel sample to be cooled is placed in the bellows body 1 in a hoisting manner and directly placed on each positioning bracket 6. The positioning bracket 6 will flip outward around the rotating shaft 7. At this time, the spring 8 between the positioning bracket 6 and the inner surface of the mounting groove 5 is in a compressed state, and the steel sample can be quickly positioned on the ventilation bracket 4;

[0040] Then, a uniform airflow is introduced into the bellows body 1 through the air inlet 2 by the blower 3 to cool the steel sample in the bellows body 1, and at the same time, the cylinder 9 is started so that its output end drives the rack 12 to slide back and forth under the guidance of the guide seat 13, and then the ventilation bracket 4 is driven to rotate synchronously through the gear ring 11 meshing with the rack 12, so that the positioned steel sample is also in a reciprocating rotation state, thereby realizing automatic cooling of the high-temperature steel sample and avoiding the manual operation of the water cooling process, which is not only inefficient but also has safety risks such as burns and spattering.
