[0038] The placement seat 19 is provided on the adjustment mechanism, and the adjustment mechanism is used to adjust the height of the placement seat 19;

[0039] A sealing mechanism is provided on the cover plate 12;

[0040] The air-cooled quenching furnace 20 is arranged on the base 1 . A feed pipe 21 is provided on the top of the air-cooled quenching furnace 20 . The feed pipe 21 cooperates with a sealing mechanism.

[0041] In this embodiment, the lifting mechanism includes a first motor 3 arranged at the top of the bracket 2, and a threaded column 4 is provided on the output shaft of the first motor 3, and a threaded block 5 is threadedly connected to the threaded column 4, and a lifting rod 6 is provided on the threaded block 5 and is slidably installed on the bracket 2, and a lifting frame 7 is provided at the bottom of the threaded block 5.

[0042] In this embodiment, the rotating mechanism includes a second motor 8 arranged on the lifting frame 7, and a cover plate 12 is provided on the output shaft of the second motor 8, a rotating column 9 is provided on the top of the cover plate 12, and a slider 10 is provided on the top of the rotating column 9, an annular slide groove 11 is opened on the lifting frame 7, and the slider 10 is slidably installed in the annular slide groove 11.

[0043] In this embodiment, the adjustment mechanism includes a dual-axis motor 13 arranged on the cover plate 12, and a winding wheel 14 is fixedly mounted on the output shaft of the dual-axis motor 13, a rope 15 is wound around the winding wheel 14, and a pull ring 16 is fixedly connected to the bottom end of the rope 15.

[0044] In this embodiment, a movable column 17 is fixedly connected to the pull ring 16 , and a placement seat 19 is provided at the bottom end of the movable column 17 . A fixed column 18 is slidably installed on the top end of the movable column 17 , and the fixed column 18 is fixedly provided on the cover plate 12 .

[0045] In this embodiment, the sealing mechanism includes a sealing groove 22 opened at the bottom of the cover plate 12 and an annular block 24 arranged at the bottom of the cover plate 12. A first annular sealing strip 23 is provided on the inner wall of the sealing groove 22, and a second annular sealing strip 25 is provided on the inner side of the annular block 24. The first annular sealing strip 23 and the second annular sealing strip 25 are both sealed with the feed pipe 21.

[0046] In this embodiment, a high chromium alloy wear-resistant part is placed on the placement seat 19, and the first motor 3 is started. The first motor 3 drives the threaded column 4 to rotate. Since the threaded column 4 and the threaded block 5 are threadedly connected, and the lifting rod 6 slides on the bracket 2, the threaded block 5 will move vertically, and the threaded block 5 drives the lifting frame 7 to move vertically, thereby driving the rotating mechanism, the cover plate 12, the adjustment mechanism and the placement seat 19 to move into the air intake cold quenching furnace 20 until the feed pipe 21 is stuck in the sealing groove 22 and is in sealing contact with the first annular sealing strip 23. At the same time, the feed pipe 21 is in sealing contact with the second annular sealing strip 25. At this time, the start of the first motor 3 is stopped. The presence of the first annular sealing strip 23 and the second annular sealing strip 25 ensures the sealing performance.

[0047] When the position of the placement seat 19 needs to be adjusted, the second motor 8 can be started, and the second motor 8 drives the cover plate 12 to rotate. Because of the presence of the first annular sealing strip 23 and the second annular sealing strip 25, the sealing during rotation can be ensured. The cover plate 12 drives the adjustment mechanism and the placement seat 19 to rotate, and the height of the air-cooled quenching furnace 20 is adjusted.

[0048] When it is necessary to adjust the height of the placement seat 19 in the air-cooled quenching furnace 20, the dual-axis motor 13 is started, and the dual-axis motor 13 drives the winding wheel 14 to rotate, thereby tightening or releasing the rope 15, thereby driving the movable column 17 to slide on the fixed column 18, adjusting the relative position of the movable column 17 and the fixed column 18, and then adjusting the height of the placement seat 19 in the air-cooled quenching furnace 20, thereby ensuring uniform quenching and avoiding affecting the quenching quality.

[0049] During quenching, the air-cooled quenching furnace 20 quenches and tempers the high-chromium alloy wear-resistant parts on the placement seat 19, and uses 1-2 MPa nitrogen or a mixed gas of helium and nitrogen for cooling and quenching.
