[0017] 2.

When the quenching agent 100 flows out, the heat can be dissipated into the air, which is beneficial to the rapid cooling of the quenching agent 100; when the quenching of the automobile leaf spring is completed, the staff can adjust the positions of the two automobile leaf spring placement racks 401 through two hydraulic cylinders B405, so as to realize the rapid removal of the automobile leaf spring after quenching. During the quenching process, the staff can take out the quenched automobile leaf spring, and then place the automobile leaf spring to be quenched in the automobile leaf spring placement rack 401, which saves the placement and removal time of the automobile leaf spring and improves the quenching efficiency of the automobile leaf spring; when the automobile leaf spring placement rack 401 moves, one of the circular guide tubes on the right 402 is separated from the arc-shaped pushing block 504. When one of the circular guide tubes 402 on the right is separated from the arc-shaped pushing block 504, the movable sealing frame 503 automatically moves to the right under the action of two reset springs B507, so that a row of circular holes B5011 is separated from a row of circular holes C5031. At this time, the quenching agent 100 in the heat sink 501 stops flowing out, ensuring that the quenching agent 100 in the heat sink 501 can flow into the automobile leaf spring quenching shell 102 under the guidance of the two rows of circular guide tubes 402, avoiding direct contact between the quenching agent 100 in the heat sink 501 and the leaf spring to be quenched, ensuring that the leaf spring to be quenched can be inserted into the quenching agent 100 together, so that the leaf spring after quenching is more consistent.
