[0025] The utility model provides the following technical solutions:

[0026] Embodiment 1

[0027] Combination Figures 1 to 5 A gas heating furnace for wheel hub forging comprises a heating furnace body 1, an exhaust passage 2 is fixedly connected to the top of the heating furnace body 1, a disassembly mechanism 3 is arranged outside the exhaust passage 2, and a sealing mechanism 4 is arranged on one side of the disassembly mechanism 3;

[0028] The disassembly mechanism 3 includes a fixed box 31, which is fixedly connected to the outside of the exhaust channel 2. A spring 32 is fixedly connected to the inner wall of the fixed box 31, one end of the spring 32 is fixedly connected to a rectangular plate 33, one side of the rectangular plate 33 is fixedly connected to a pushing frame 36, a connecting rod 34 is fixedly connected to the side of the rectangular plate 33 away from the pushing frame 36, a section of the connecting rod 34 away from the rectangular plate 33 is fixedly connected to a clamping block 35, one side of the pushing frame 36 is fixedly connected to a connecting block 37, a supporting block 38 is fixedly connected to the front of the exhaust channel 2, a connecting shaft 39 is fixedly connected to the top of the supporting block 38, and a dislocation block 301 is rotatably connected to the top of the connecting shaft 39.

[0029] Furthermore, the rectangular plate 33 is slidably connected to the inner wall of the fixed box 31, and a dislocation opening is provided inside the connecting block 37. The size of the dislocation block 301 is larger than the size of the dislocation opening, so that the dislocation block 301 can move through the dislocation opening.

[0030] Furthermore, a moving opening is opened on one side of the fixed box 31 close to the pushing frame 36 , and the pushing frame 36 passes through the moving opening and moves, so that the pushing frame 36 can move through the moving opening.

[0031] Furthermore, a round hole is opened on one side of the fixing box 31 close to the connecting rod 34 , and the connecting rod 34 passes through the round hole and moves, so that the connecting rod 34 can move through the round hole.

[0032] Embodiment 2

[0033] See also Figures 1 to 4 On the basis of the first embodiment, the sealing mechanism 4 further comprises a limit frame 41, the limit frame 41 is fixedly connected to the inner wall of the exhaust passage 2, a slider 42 is slidably connected to the inner wall of the limit frame 41, a sealing block 44 is fixedly connected to the front of the slider 42, a sealing cover 45 is fixedly connected to the front of the sealing block 44, and a purifier 43 is fixedly connected to the inner side of the slider 42, so as to further ensure the stability of filtering and purification.

[0034] Furthermore, the purifier 43 is fixedly connected to the back side of the sealing block 44 , and the sealing block 44 is movably connected to the front side of the exhaust passage 2 , so as to stably seal the inside of the exhaust passage 2 .

During the discharge process, the purifier 43 can filter and purify. Then, when the slider 42 needs to be disassembled and replaced, the push frame 36 can be pushed to move, so that the push frame 36 can drive the rectangular plate 33 to move and compress the spring 32, and the rectangular plate 33 drives the block 35 to disengage from the rectangular opening opened by the sealing cover 45 through the connecting rod 34, and cancels the limit of the sealing block 44. When the block 35 is completely moved out of the rectangular opening, the push frame 36 will also drive the connecting block 37 to completely penetrate the dislocation block 301, and then the dislocation block 301 is selected to rotate along the axis point of the connecting shaft 39, so that the dislocation block 301 and the dislocation opening opened by the connecting block 37 are dislocated, and then the push frame 36 can be limited, so that the block 35 cannot move, which is convenient for further disassembly and replacement of the sealing mechanism 4. During the disassembly process, good disassembly efficiency can be achieved, and the convenience of operation and use is enhanced.

[0037] When the limit on the sealing cover 45 is cancelled, the sealing block 44 can be pulled out from the outside of the exhaust channel 2, the sealing block 44 can be pulled out from the front of the exhaust channel 2, and the slider 42 can slide out from the inner wall of the limit frame 41, and the purifier 43 can be pulled out from the inside of the exhaust channel 2, and the purifier 43 can be disassembled. While achieving rapid disassembly, the sealing performance can be guaranteed by the mutual cooperation of the sealing block 44 and the sealing cover 45, and the slider 42 and the limit frame 41 ensure the stability of the limit sliding.
