[0039] Working principle: The pipe to be cut is placed between the two belts 26 (the distance between the two belts 26 is adapted to the diameter of the pipe to be cut, and the distance between the two belts 26 is adjusted by starting the double-headed cylinder 202 to extend and retract its movable end, and the guide sleeve 22 slides along the guide rod 21 to adjust the distance between the two connecting plates 23, thereby changing the distance between the two belts 26), and the drive motor A28 drives the rotating shaft 24 to drive the pulley 25, so that the two belts 26 rotate in opposite directions at the same time (the left drive motor A28 reverses, and the right drive motor A28 rotates forward, that is, the left belt 26 rotates counterclockwise and the right belt 26 rotates clockwise The cutting blade 32 rotates and moves to the left along the right end of the pipe to cut the rear end of the pipe. The cutting blade 32 stops rotating and returns to the vertical state. The cut pipe is left on the groove 45 of the feeding plate 44 (when the pipe is cut on the groove 45, it is located on the same plane as the pipe between the belts 26, that is, the pipe does not move downward or offset at this time). The feeding plate 44 is dropped by the telescopic cylinder A47, so that the pipe falls on the inclined plate 42 and slides between the two support rollers 52 at the right end. The cut pipe is clamped by the clamping assembly (when clamping the pipe, the lifting cylinder A3 drives the support frame 54 to move downward, so that the clamping plate 56 is located on both sides of the pipe, and the driving motor in the support frame 54 drives the two rotating seats 55 to rotate in the opposite direction, so that the clamping plate 56 clamps the pipe, and the lifting cylinder A3 drives the support frame 54 to move upward, so that the pipe is removed from between the two support rollers 52, and the clamping assembly is moved to the next group of support rollers 52, so that the clamping plate 56 releases the pipe. At this time, the pipe is processed on the current group of support rollers 52), and the clamping assembly is slid to the corresponding position of the inner grinding mechanism 6 through the cylinder, and is loosened so that the pipe is located on the two support rollers 52 in the middle, and the pressing block 6 is pressed by the telescopic cylinder B62. 3 moves downward to press the pipe fitting (wherein the pressing block 63 is an arc-shaped plate that fits the curvature of the pipe fitting), drives the inner grinding roller 68 to rotate through the driving motor C67, and moves the inner grinding roller 68 backward to the inside of the pipe fitting through the sliding assembly to grind the inner wall of the pipe fitting; clamps the pipe fitting whose inner wall has been polished through the clamping assembly, slides the clamping assembly to the position corresponding to the outer grinding mechanism 7, and releases it so that the pipe fitting is located on the two supporting rollers 52 at the left end, drives the outer grinding roller 74 to rotate through the driving motor D73, and moves the outer grinding roller 74 downward to abut against the outer wall of the pipe fitting through the sliding assembly to grind the outer wall of the pipe fitting; clamps the pipe fitting whose outer wall has been polished through the clamping assembly, moves it to the leftmost end, and releases the clamping assembly so that the pipe fitting falls into the collection box.

An automated production method for pipe processing, characterized in that: The following steps are involved: S1: placing the pipe to be cut between the two belts (26), and making the two belts (26) rotate in opposite directions at the same time, driving the pipe to be cut to move backward until it contacts the top plate; S2: The cutting blade (32) is rotated one circle to cut off the rear end of the pipe, and the cut pipe is located on the groove (45) of the feeding plate (44); S3: The feeding plate (44) is lowered by the telescopic cylinder A (47), so that the pipe falls on the inclined plate (42) and slides between the two supporting rollers (52); S4: clamping the cut pipe by a clamping assembly, sliding the clamping assembly to a position corresponding to the inner grinding mechanism (6), and releasing the clamping assembly so that the pipe is located on two supporting rollers (52); S5: moving the inner grinding roller (68) back to the inside of the pipe fitting to grind the inner wall of the pipe fitting; S6: clamping the pipe with the inner wall polished by a clamping assembly, sliding the clamping assembly to a position corresponding to the outer polishing mechanism (7), and releasing the clamping assembly so that the pipe is located on two support rollers (52); S7: moving the outer grinding roller (74) downward to abut against the outer wall of the pipe fitting to grind the outer wall of the pipe fitting; S8: Clamp the pipe with polished outer wall by the clamping assembly, move to the leftmost end, release the clamping assembly and let the pipe fall into the blanking box (11).
