Ring piece automatic multi-frequency array ultrasonic nondestructive testing device and method

Abstract

The invention discloses an automatic multi-frequency array ultrasonic non-destructive testing device and method for ring parts. An array of multi-frequency probes on the end face, a multi-channel ultrasonic detector, an industrial computer, and a control cabinet; the array of multi-frequency probes on the outer circular surface includes multiple columns of probes with different frequencies, which are used to detect defects at different radial depths of rings, The end-face multi-frequency probe array includes multiple rows of probes with different frequencies, which are used to detect defects at different depths in the axial direction of the ring. The invention uses multi-frequency array probes to realize automatic layered detection of internal defects of ring parts, and has the advantages of high efficiency, simple operation, small detection blind area, high detection precision, strong adaptability and the like.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic non-destructive testing, and specifically relates to an automatic multi-frequency array ultrasonic non-destructive testing device and method for ring parts. It selects different frequency probes to detect defects in different depths of ring parts, and is suitable for internal defects of ring parts of different sizes. Quantitative detection. Background technique [0002] Ring products are widely used in wind power generation, power transmission, marine equipment, engineering machinery, light industrial machinery, metallurgical machinery and other industries. In service, they have the characteristics of frequent braking, repetition, large impact load, and withstand alternating stress. , requiring high strength, high toughness and good fatigue resistance. Ring rolling is currently the preferred technology for producing high-performance ring forgings. However, during the rolling process, various t...

Problems solved by technology

However, the problem is that the detection results of this method are easily affected by the operating experience and fatigue of the inspectors, and the detection efficiency is low, the missed detection rate is high, the detection blind area is large, and it is difficult to achieve quantitative detection of defects. How to improve the detection accuracy and detection efficiency, reducing detection blind spots, and simultaneously realizing the automatic quantitative detection of internal defects of rings is the key to the research of the present invention
