The air delivered to the inside of the main frame body 1 exchanges heat with the cooling liquid circulated in the serpentine circulating pipe 403, forms low-temperature air, and the wave-shaped baffle 405 also slows down the flow of air, so that the air delivered to the inside of the main frame body 1 by the fan 404 can stay longer and exchange heat with the cooling liquid more fully. Finally, the low-temperature air is delivered to the upper side of the main frame body 1 through the first through hole 406 and the second through hole 407, so as to cool the area above the main frame body 1, avoid the components in the driving mechanism 2 and the positioning mechanism 3 from being damaged due to overheating, and be suitable for conveying of the bearing hot forgings in a high-temperature environment.
