The above document still has shortcomings. When in use, the heating treatment of the non-standard chain is achieved by a heating gun, and then the rotating rod is driven to rotate by the motor, and then the placement table is driven to rotate by the rotating rod to achieve uniform rotation of the non-standard chain during the heating process, so that the non-standard chain is heated evenly during the heating treatment. However, when the placement table rotates, the chain is easily caused to fall off due to centrifugal force, and it is not convenient to position the chain when the chain is heat treated, so that the heat treatment device cannot heat treat the chain. At the same time, the coolant is discharged from the drain outlet after a round of cooling operation, resulting in a waste of resources and inconvenience for recycling the coolant.

[0037] Coolant circulation phase:

[0038] The coolant sprayed by the sprinkler 13 passes through the through hole in the horizontal plate 2 and falls onto the filter 406. The filter 406 filters the impurities in the coolant. The filtered coolant enters the water tank 401 and then continues to be extracted by the water pump 12 through the water pipe 402. After the chain 11 is cooled, the protective door under the box body 1 is opened, and the bracket 405 is lifted. The bracket 405 drives the filter 406 and the long board 404 to move, and the long board 404 is separated from the bracket 403. The bracket 405, the filter 406 and the long board 404 are taken out to clean the filter 406 to avoid clogging of the filter 406.
