[0051] The synchronous chamfering mechanism 19 includes a support platform 191, a fifth telescoper 192, a first rotary motor 193, a plurality of second rotary motors 194, and a plurality of chamfering cutters 195.

[0056] Working principle: First, roll the large-sized pipe flange and push it into the feeding box 1 from the feeding port 6. The first telescopic device 4 extends, and the first flat pressing plate 5 pushes the pipe flange into the feeding channel 3. The first telescopic device 4 retracts, creating space at the feeding port 6 for the next feeding. This process is repeated to achieve continuous feeding. Secondly, the third telescopic device 15 extends, and the third flat pressing plate 16 pushes the pipe flange that has slid from the feeding channel 3 to the first transition port 7 into the transition slide rail 13. At this time, the fourth telescopic device 17 extends, and the fourth flat pressing plate 18 blocks the second transition port 12. The fourth flat pressing plate 18 and the third flat pressing plate 16 clamp the pipe flange. Then, the vision camera 22 captures the pattern and characteristics of the screw holes, and the first rotary motor 193 rotates to compensate for the position deviation between the chamfering tool 195 and the screw holes, enabling the multiple chamfering tools 195 to align with the multiple screw holes on the pipe flange. The fifth telescopic device 192 pushes the first rotary motor 193 and other structures closer to the pipe flange. At this time, the first rotary motor 193 slides along the slideway 21, and the second rotary motor 194 rotates to drive the chamfering tool 195 to rotate. The chamfering tool 195 extends into the screw holes and chamfers the screw holes, thereby completing the synchronous chamfering of multiple screw holes. After the processing is completed, the first rotary motor 193 and the multiple second rotary motors 194 stop rotating, and the fifth telescopic device 192 retracts to drive the first rotary motor 193 and other components to reset. Finally, the fourth telescopic device 17 retracts, and the fourth flat pressing plate 18 moves away from the second transition port 12 and resets. The third telescopic device 15 continues to extend, and the third flat pressing plate 16 acts on the pipe flange and pushes it from the second transition port 12 into the discharge channel 9. Subsequently, the third telescopic device 15 retracts to drive the third flat pressing plate 16 to reset. The second telescopic device 10 extends, and the second flat pressing plate 11 pushes the pipe flange into the discharge channel 9. The second telescopic device 10 retracts, creating space at the second transition port 12 for the next discharging. This process is repeated to achieve continuous discharging. The pipe flange is heated by the induction heater 23 during the discharging process in the discharge box 8 and insulated in the discharge channel 9, thereby completing the heat treatment operation. The pipe flange after insulation is discharged one by one from the discharge port 14.
