2) Cutting: starting a hydraulic cylinder 58, driving the cutting unit 5 to move forwards along the first rail 52, starting a first motor 57, enabling the cutting blade 56 to rotate at a high speed, cutting the steel pipe, and automatically drawing the protection housing 12 from the chute 41 by the cut steel pipe; after the cutting is finished, the first motor 57 is turned off, the hydraulic cylinder 58 drives the cutting unit 5 to move backwards along the first rail 52, and the steel pipe continues to extend out for a certain distance to cut the next section;
3) And (3) transmission pipe: the steel pipe slides from the conveyor belt 7 and the rolling plate 71 to the circular groove opening of the frame 85, the lifting cylinder 24 is started to lift the baffle 241 to the two sides of the steel pipe, the fourth cylinder 25 is started to drive the sliding block 23 to move forwards along the second track 22, the steel pipe is pushed to correct the position of the steel pipe, the steel pipe is symmetrically placed in the circular groove opening, and after the steel pipe is symmetrical, the baffle 241 and the sliding block 23 are reset;
4) Chamfering: starting a second air cylinder 82, driving a pressure head 83 to press down, fixing a steel pipe positioned on a circular notch of a frame 85, starting a third air cylinder 89, driving a rotary lathe tool holder 84 to be close to the end part of the steel pipe, starting a second motor 82, rotating the lathe tool holder 84, and chamfering two ends of the steel pipe; wherein, according to the difference of the inner and outer chamfers, the turning tool 841 can be replaced;
5) Discharging: after chamfering, the rotary lathe saddle 84 stops rotating and retreats, the fifth cylinder 27 is started to drive the rotary rod 28 to rotate upwards, barbs at the end part of the rotary rod 28 pick out the steel pipes in the round notch, and the steel pipes slide out of the discharging groove plate 10.
By way of example, through the above steps, the unprocessed steel pipe in fig. 24 becomes a steel pipe with a regular outer chamfer in fig. 25.
While the foregoing describes illustrative embodiments of the present application so that those skilled in the art may understand the present application, the present application is not limited to the specific embodiments, and all applications and creations utilizing the inventive concepts are within the scope of the present application as long as the modifications are within the spirit and scope of the present application as defined and defined in the appended claims to those skilled in the art.
