Automatic flaw detector for pipe billet

TLDR: In this article, an automatic flaw detector for the pipe billet of seamless steel pipe was proposed. But the defect detection process was performed under the microcomputer control by matching with an eight-channel computerized ultrasonic flaw detector.

Abstract: The utility model relates to an automatic flaw detector for the pipe billet which is the equipment used for the online or off-line flaw detection for variable diameter bar materials and variable length bar materials of the pipe billet of seamless steel pipe, and the automatic flaw detector for the pipe billet can automatically work under the microcomputer control by matching with an eight-channel computerized ultrasonic flaw detector. The pipe billet conveying by a step feed machine, the rotation of the pipe billet and the walk of a probe carriage all adopt a planetary speed reducer for transmission. The utility model can adopt variable distance step feed mechanism, a cylindric type following cylinder, a crawler type creel stand, a rotary device, a combined type probe, a rocking arm type marking machine and a vertical type walking carriage. The probe can automatically lift, falling, automatically identifying the defect, and automatically marking. The defection speed can reach to 9 meters/ minute.
