When the bar 48 is detected and conveyed out of the flaw detection table 3, when the lifting oil cylinder of the blanking conveying frame 2 is lifted, the lifting support 8 and the fixed support 9 are at the same height, the bar 48 sent out of the flaw detection table 3 is received, then the lifting oil cylinder is lowered, the bar-shaped conveying plate 7 is inclined, and a worker can conveniently detach the bar 48 from the bar-shaped conveying plate 7; the worker can cut out the defective portion according to the mark on the surface of the bar 48 and put the bar 48 without the defective portion in stock for use.
