A flaw detection and processing system for a steel plate coiler

Abstract

A flaw detection and processing system for a steel pipe reel, which relates to the technical field of automobile exhaust pipe production equipment, including a pipe reel body, the pipe reel body has a unique pipe exit direction, and the pipe exit direction of the pipe reel body extends with flaw detection processing The flaw detection processing device includes a guide rail perpendicular to the pipe discharge direction of the coiler and a mover that can be moved on the guide rail through a walking device. device, surface quality inspection device and cutting device; the body of the coiling machine is also provided with a first encoder. The flaw detection and processing system of the steel pipe coiler can realize the flow flaw detection and processing of the welded seamless steel pipe. The invention has the advantages of good detection quality, comprehensive and rapid detection, high defect detection processing efficiency, high working precision, saving material waste, reducing labor intensity of workers, and high degree of automation.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipe production equipment, in particular to a flaw detection and processing system for a steel pipe coiler. Background technique [0002] In the process of producing seamless steel pipes for automobile exhaust pipes, manufacturers of automobile exhaust pipes usually use coiling pipes, pipe coiling machines, and grinding machines to bend thin steel strips into tubular shapes, and then perform grinding on both ends of the coils. Welding, the seamless steel pipe is formed by welding and grinding the weld seam. After welding, the weld seam of the seamless steel pipe will have defects such as low melting point slag inclusions and pores, and the exhaust pipe is always under high temperature and high pressure during the working process of the car. These defects, especially the defects on the surface of the pipe wall, are subject to stress during operation, and are prone to fatigue cracks, whic...

Problems solved by technology

This technical solution has the following disadvantages: First, the steel pipe is a thin-walled part, and the ultrasonic reflection surface is relatively close, so it is difficult for the ultrasonic flaw detection to form an effective echolocation for the defect; second, the spraying of flaw detection fluid may not completely cover the flaw detection surface, It will also lead to a decline in the effect of flaw detection; thirdly, corresponding processing cannot be carried out after flaw detection, and additional processing procedures are required or defective products are scrapped after production is completed, which is a serious waste; finally, manual screening and picking are required, with low automation and low efficiency. Low, labor intensity is high
