Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Example 1

Referring to fig. 1-5, a quenching device comprises a shell 1, wherein a lifting component 2 is arranged on one side of the top of the shell 1, a cooler 3 is arranged on one side of the shell 1 away from the shell, sealing blocks 4 are arranged on one side, close to the shell 1, of two connecting pipes of the cooler 3, the two sealing blocks 4 penetrate through the shell 1, and a coil pipe 5 is arranged between the two connecting pipes of the cooler 3 in the shell 1; the coil pipe 5 is positioned in a cavity between the protective cover 6 and the shell 1, and the protective cover 6 is provided with a plurality of flow holes 10.

The shell 1 is provided with two connecting channels (the connecting channels are arranged corresponding to the two connecting pipes 3 of the cooler 3), the two sealing blocks 4 penetrate through the connecting channels of the shell 1, and the sealing blocks 4 enable the two connecting pipes of the cooler 3 to be in sealing fit with the connecting channels of the shell 1, so that quenching medium added in the shell 1 is prevented from leaking from the connecting pipes of the cooler 3.

By arranging the protective cover 6, mechanical parts needing quenching can be prevented from contacting with the coil pipe 5 arranged in the shell 1 after entering the shell 1, so that the damage probability of the coil pipe 5 is reduced, and the coil pipe 5 is protected.

The cooler 3 is controlled by a control switch arranged outside, so that the cooling liquid in the coil pipe 5 flows, and after the quenching medium in the shell 1 is cooled by the cooling liquid in the coil pipe 5, the cooling speed of the quenching medium in the shell 1 is increased, thereby reducing the time required by quenching mechanical parts in the shell 1.
