and then, clamping the ith pipe bar to be subjected to ultrasonic flaw detection by a feeding pinch roll (2-4), and conveying the ith pipe bar to be subjected to ultrasonic flaw detection to an inlet clamp of the ultrasonic flaw detection equipment (1).
8. The transmission sorting method for ultrasonic flaw detection and eddy current flaw detection of a pipe and a rod material according to claim 6, wherein: in step 201, after the third sensor detects that the tail part of the pipe and bar subjected to ultrasonic flaw detection is separated from the outlet clamp holder of the ultrasonic flaw detection equipment (1), conveying the pipe and bar subjected to ultrasonic flaw detection to a blanking roller way (3-2) by a discharging pinch roll (3-5); after the fourth sensor detects that the pipe and rod material after the ultrasonic flaw detection is linearly moved in place along the blanking roller way (3-2), step 202 is executed.
9. The transmission sorting method for ultrasonic flaw detection and eddy current flaw detection of a pipe and a rod material according to claim 6, wherein: in step 202, when the unqualified pipe bar subjected to ultrasonic flaw detection is a pipe bar to be reworked, the pipe bar to be reworked is stirred to a material frame layer (3-4-2) to be reworked by a sorting stirring device (11), and the specific working process is as follows: the piston rod of the sorting driving cylinder (11-4) is retracted, the connecting rod (11-3) drives the stirring rod (11-2) to turn around the rotating shaft (11-5) anticlockwise until the stirring rod (11-2) is bridged on the blanking hole, so that the blanking hole is in a closed state, and at the moment, a pipe rod to be reworked slides on the tail end of the work frame layer (3-4-2) to be reworked through the stirring rod (11-2);
When the unqualified pipe rod subjected to ultrasonic flaw detection is a non-reworkable pipe rod, stirring the non-reworkable pipe rod to a non-reworkable material frame layer (3-4-3) by a sorting stirring device (11); the specific working process is as follows:
the piston rod of the sorting driving cylinder (11-4) stretches out, the connecting rod (11-3) drives the stirring rod (11-2) to turn around the rotating shaft (11-5) until the blanking hole is in an open state, at the moment, the non-reworkable pipe bar can fall onto the non-reworkable material frame layer (3-4-3) through the blanking hole and slide to the tail end of the non-reworkable material frame layer (3-4-3).
10. The transmission sorting method for ultrasonic flaw detection and eddy current flaw detection of a pipe and a rod material according to claim 6, wherein: in step 301, after the fifth sensor detects that the pipe and bar to be subjected to eddy current inspection is discharged in place, the third puller (13) conveys the pipe and bar to be subjected to eddy current inspection in place to the first conveying track (4);
in step 302, after the sixth sensor detects that the pipe bar to be subjected to eddy current inspection moves in place along the first transmission track (4), the pipe bar to be subjected to eddy current inspection enters the second transmission track (6) after passing through the open-close type transition door (5);
in step 303, after the seventh sensor detects that the pipe and bar to be subjected to eddy current inspection moves in place along the second conveying track (6), the pipe and bar to be subjected to eddy current inspection on the second conveying track (6) is conveyed to the transition material rack (16) by using a fourth shifter (15).
