[0019] Working principle: The first hydraulic cylinder 5 can be supported by the support 4. There is no need to fix the first hydraulic cylinder 5 inside the furnace body 1. The first hydraulic cylinder 5 can be used at room temperature, which can prevent the high temperature of the induction coil 14 in the furnace body 1 from being transmitted to the first hydraulic cylinder 5 and causing damage to the sealing ring of the first hydraulic cylinder 5. The sealing and normal operation of the first hydraulic cylinder 5 can be guaranteed. First, the hydraulic rod of the second hydraulic cylinder 10 is controlled to retract and open the insulation cover 2. Then, the gear coupling components to be processed are placed on the support plate 15. Then, the hydraulic rod of the second hydraulic cylinder 10 is controlled to retract. After the push rod 17 is reset, it stops supporting the insulation cover 2. The insulation cover 2 can be closed by its own weight. Then the hydraulic rod of the first hydraulic cylinder 5 is controlled to extend. The hydraulic rod of the first hydraulic cylinder 5 can adjust the height of the scissor frame 16 through the straight rod 6. The scissor frame 16 will The parts are lifted into the induction coil 14, and the induction coil 14 can quench the parts of the coupling. Since the distance between the two push rods 17 is greater than the width of the support plate 15, the push rod 17 can be prevented from interfering with the lifting and lowering activities of the support plate 15. After the parts of the coupling are quenched, the staff controls the hydraulic rod of the first hydraulic cylinder 5 to retract. The hydraulic rod of the first hydraulic cylinder 5 can drive the scissors frame 16 to reset through the straight rod 6, and can drive the gear coupling parts to descend. The hydraulic rod of the second hydraulic cylinder 10 is controlled to retract again. The hydraulic rod of the second hydraulic cylinder 10 can push the unloading plate 18 through the bent rod 11. The unloading plate 18 can push the coupling parts after heat treatment to move. During the movement of the unloading plate 18, the two push rods 17 can be driven to move. When the two push rods 17 move, they contact the insulation cover 2 and can synchronously push open the insulation cover 2, so that the material can be automatically unloaded through the insulation cover 2.

[0020] The operating principle of the scissor frame 16 is: the hydraulic rod of the first hydraulic cylinder 5 pushes the straight rod 6 to move, the straight rod 6 pushes the first slider 163 to slide, the first slider 163 pushes the first support rod 161 and the second support rod 162 to rotate relative to each other, thereby pushing the support plate 15 to rise and fall. At this time, the second slider 166 slides at the bottom of the support plate 15.
