the SS01 uses a crown block or a lifting appliance to move the material to be detected onto a feeding rack (302), and the material on the feeding rack (302) can be transferred onto a conveying roller way (301) at one end of a first flaw detection device (1) through a walking beam (304);
SS02 transfers one end of the material to the compression roller assembly (4) through the conveying roller way (301), drives the pinch roller (406) to descend through the lifting device (409) and the cylinder (405), is matched with the lower supporting wheel (407) to bite the material, and drives the lower supporting wheel (407) to operate through the second motor (105) to drive one end of the material to pass through the centering assembly (6) to move into the rotating sleeve (5);
before detection, SS03 adjusts the space among three centering wheels (603) on the centering assembly (6) through the material specification to be detected, and simultaneously adjusts the height of the lifting table (103), so that the center point of the space formed among the three centering wheels (603) and the blocking head (708) are concentric with the material;
when one end of the SS04 material moves to the end of the blocking head (708), stopping the operation of the conveying roller way (301) and the second motor (105) can limit the position of the material;
the SS05 operates the first motor to drive the rotary sleeve (5) to rotate, flaw detection treatment can be carried out on the end part of the material through the wireless ultrasonic probe (502), and obtained data are transmitted into the upper computer for analysis;
after flaw detection of one end of the SS06 material is finished, the end part of the material is moved out of the first flaw detection device (1) through a conveying roller way (301), the material is moved onto the other conveying roller way (301) through a walking beam (304), and the other end of the material is moved into the second flaw detection device (2) in the same way to carry out flaw detection treatment of the other end;
the SS07 moves the detected material out of the second flaw detection device (2) through a conveying roller way (301) and transfers the detected material to a discharging bench through a walking beam (304).
