[0035] Another technical problem to be solved by the present invention is to provide a chamfering method for a pipe end chamfering machine for a steel pipe, comprising the following steps: Steel pipe feeding The steel pipe to be chamfered is placed on the conveyor belt 391, and after being placed, it is transported by the conveyor belt 391 to the middle position corresponding to the mounting plate 35, and the mounting plate 35 is controlled to move, so that the upper fixing plate 37 and the lower fixing plate 36 clamp the steel pipe, and the loading operation is completed; Chamfering After the steel pipe is clamped, the disc 41 is controlled to move toward the two ends of the steel pipe, and the chamfering knife 493 is further controlled to contact the end of the steel pipe, and the rotary chamfering operation is performed as the disc 41 rotates.

When the steel pipe contacts the lower fixed plate 36 inside the mounting plate 35, the first electric push rod 38 works and pushes the upper fixed plate 37, so that the upper fixed plate 37 squeezes the steel pipe on the lower fixed plate 36 to form a clamping effect. Then, the above operation is repeated to control the movement of the mounting plate 35 until the axis of the steel pipe and the axis of the disc 41 are at the same height position. After the steel pipe is clamped, in order to improve the stability of the mounting plate 35, the third motor 498 works and pushes the control plate 383, the control plate 383 drives the rack 384 to move, the rack 384 drives the first gear 385 to rotate, the first gear 385 drives the second bidirectional threaded rod 381 to rotate, the second bidirectional threaded rod 381 drives the two long plates 398 to move towards each other, and after the long plate 398 moves, it drives the contact plate 399 to move and fit tightly to the mounting plate 35, forming a clamping effect, thereby further improving the stability of the mounting plate 35, and correspondingly ensuring that the steel pipe can be processed in a stable environment; After the fourth electric push rod 482 works, it pushes the movable plate 481, and the movable plate 481 drives the square rod 43 to move, and the square rod 43 drives the first sleeve 44 and the turntable to move synchronously, and the first sleeve 44 drives the frame plate 42 to move, and the distance between the frame plate 42 and the turntable remains unchanged, then the third motor 498 works and drives the third bidirectional threaded rod 497 to rotate, and the third bidirectional threaded rod 497 drives the two moving blocks 496 to move towards or away from each other, and after the moving block 496 moves, it drives the second pull rod 499 to flip, and after the second pull rod 499 flips, it pushes the adjusting plate 48, prompting the adjusting plate 48 to move horizontally, and after the adjusting plate 48 moves, it drives the extension plate 495 to move, and after the extension plate 495 moves, it also drives the first pull rod 494 to flip, and after the first pull rod 494 flips, it pushes the adjusting block 492 The second gear 484 drives the third gear 485 to rotate, and the third gear 485 drives the second sleeve 45 to rotate, and the second sleeve 45 drives the square rod 43 to rotate, and the square rod 43 drives the turntable to rotate. It can be seen from the above connection relationship that the chamfering knife 493 revolves around the square rod 43 at this time, so as to perform synchronous chamfering processing on the two ends of the steel pipe, which is more efficient than the method of processing only one end of the steel pipe at a time. Finally, after the chamfering process is completed, repeat the above similar steps and place the processed steel pipe on the conveyor belt 391, so that the processed steel pipe can continue to be conveyed for unloading, and the next steel pipe to be processed can be conveyed to the processing position for processing. Compared with manual loading and unloading, it saves more manpower.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
