Abstract
The invention discloses a medium temperature homogenization quenching device. Check rings enter a first chamber of a quenching bath from a work-piece inlet, are conveyed by a conveying mechanism to sequentially pass through a second chamber and a third chamber and are discharged from a work-piece outlet. In the quenching process, a liquid guide mechanism guides quenching media, with a low temperature, in the third chamber into the first chamber, the check rings firstly make contact with the media, with a low temperature, from the third chamber, the media enter the second chamber or the third chamber after being heated, and therefore the check rings make contact with the media with a low temperature after entering the first chamber. A blending mechanism achieves heat exchange among the first chamber, the second chamber and the third chamber. The medium temperature homogenization quenching device is reasonable in structural design, the temperature of quenching media in the quenching bath can be homogenized by simply modifying an existing quenching device, and therefore the check rings can always make contact with the media with a low temperature in the quenching bath.
