[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a vacuum air quenching furnace for metal heat treatment with an adjustable damper includes a vacuum furnace 1, an exhaust pipe 5 is fixedly connected to the top of the vacuum furnace 1, a ventilation pipe 4 is fixedly connected to one side of the vacuum furnace 1, a rotating component is provided at the bottom of the ventilation pipe 4, a wind shield plate 3 is equidistantly rotatably connected to the inside of the ventilation pipe 4, a slide groove 9 is provided inside the ventilation pipe 4, a baffle 2 is slidably connected to the inside of the slide groove 9, a vertical plate 8 is fixedly connected to the top of the ventilation pipe 4, an adjustment component is provided on one side of the vertical plate 8, and a feed door 6 is rotatably connected to one side of the vacuum furnace 1.

[0022] First, when adjusting the size of the air inlet of the ventilation duct 4, the adjustment component on one side of the vertical plate 8 is started to drive the baffle 2 to move inside the slide groove 9, thereby blocking the air inlet of the ventilation duct 4. This can conveniently adjust the size of the air inlet, thereby increasing the flexibility of the device. Then, when adjusting the wind direction, the rotating component at the bottom of the ventilation duct 4 is started to operate, thereby driving multiple wind shields 3 to rotate, thereby adjusting the wind direction of the incoming air. Cooperating with the adjustment component can avoid the problem of being unable to adjust the wind direction and air volume of the incoming air, and being unable to flexibly process workpieces of different shapes and specifications, which affects the processing efficiency and quality, thereby increasing the practicality of the device.

The adjustment component also includes a fixed frame 16, which is fixedly connected to one side of the baffle 2. A protrusion 17 is fixedly connected to one side of the turntable 10, and the outer side of the protrusion 17 is slidably connected to the inner wall of the fixed frame 16.

[0024] When adjusting the size of the air inlet, the output shaft of the starting motor 7 is rotated to drive the turntable 10 to rotate and drive the protrusion 17 to slide inside the fixed frame 16, and then drive the baffle 2 to reciprocate inside the slide groove 9, so that the size of the air volume can be conveniently adjusted.

[0025] like Figure 1-Figure 4 As shown, the rotating assembly includes a gear 11, which is rotatably connected to the bottom of the ventilation pipe 4, and one end of the rotating shaft of the gear 11 is fixedly connected to one end of the rotating shaft of the wind shield 3. The rotating assembly also includes a fixed frame 15, which is fixedly connected to the bottom of the ventilation pipe 4, and the internal sliding connection of the fixed frame 15 is connected to the displacement plate 13, and the top of the fixed frame 15 is fixedly installed with a cylinder 14, one end of the movable rod of the cylinder 14 is fixedly connected to one side of the displacement plate 13, and one side of the displacement plate 13 is fixedly connected to a rack 12, and one side of the rack 12 is meshed with the outer side of the gear 11.

[0026] When adjusting the wind direction, the movable rod of the cylinder 14 is started to move, driving the displacement plate 13 to slide inside the fixed frame 15 and driving the rack 12 to move, thereby driving the multiple gears 11 to rotate and driving the multiple wind shields 3 to rotate, thereby adjusting the wind direction.

[0027] The utility model provides a vacuum air quenching furnace for metal heat processing with an adjustable air door, and the specific working principle is as follows: first, when adjusting the size of the air inlet, the output shaft of the starting motor 7 is rotated to drive the turntable 10 to rotate and drive the protrusion 17 to slide inside the fixed frame 16, and then drive the baffle 2 to move back and forth inside the slide groove 9, so that the size of the air volume can be conveniently adjusted. Finally, when adjusting the wind direction, the movable rod of the starting cylinder 14 is moved to drive the displacement plate 13 to slide inside the fixed frame 15 and drive the rack 12 to move, thereby driving multiple gears 11 to rotate and drive multiple wind shielding plates 3 to rotate, thereby adjusting the wind direction of the incoming air.
