Then, the adjusting screw 1201 is controlled; by rotating the adjusting screw 1201, the lifting and lowering are adjusted, causing the limit seat 1203 to descend. The steel pipe is then placed in the limit groove 1204 at the bottom of the limit seat 1203, which fixes the steel pipe in place. The solenoid valve is then controlled via the control key, which in turn controls the hydraulic cylinder 8, allowing for arbitrary stopping positions of the hydraulic cylinder 8. The lifting frame 9... Adjust the connecting plate 10 up and down, start the motor 11, the motor 11 drives the cutting blade 14 to rotate, and cut the steel pipe during the descent. During the cutting process, after the cutting blade cuts the steel pipe, it is placed in the strip groove 4. Then the hydraulic cylinder 8 drives the cutting blade 14 to rise. Control the adjusting screw 1201 to lift the limit seat 1203 and separate it from the steel pipe. Control the motors at the rear of the first conveying device 2 and the second conveying device 3 respectively. The two motors drive the two drive shafts to rotate in opposite directions, so that the two conveyor belts 33 transmit in opposite directions, realizing the separate conveying of the pipe head and the pipe tail.
