Problems solved by technology

Not only the workload is very heavy, but also there are inevitably detection blind spots, resulting in missed detection
All in all, the current level of non-destructive testing of large-scale die steel is still relatively backward, mainly due to key problems such as low detection efficiency, low detection accuracy and many human errors

Abstract

The invention discloses an automatic ultrasonic scanning method and device for die steel. As a mechanical hand mechanism, an ultrasonic probe, a work slot mechanism and a data processor are matched, in the whole scanning and detecting process, the mechanical hand mechanism executes a path designed in advance, under driving of a mechanical hand, the ultrasonic probe executes scanning and detecting tasks and feeds back data, the data is processed by the data processor in real time, obtained scanning results are displayed on a computer in real time, automatic ultrasonic scanning and detection of die steel is achieved, detection efficiency and detection accuracy are improved, and man-made detection errors are avoided. In addition, as a coupling agent circulating assembly is arranged, a coupling agent in the work slot mechanism is treated more scientifically and reasonably, cyclic utilization of the coupling agent is optimized, and the coupling effect is improved.

Description

technical field [0001] The invention relates to ultrasonic automatic flaw detection technology, in particular to an automatic ultrasonic scanning method and equipment for mold steel. Background technique [0002] Ultrasonic flaw detection is a method for inspecting parts defects by using ultrasonic energy to penetrate deep into the metal material and pass from one section to another section, reflecting at the edge of the interface to inspect parts defects. Inside the metal, when a defect and the bottom surface of the part are encountered, reflected waves will be generated respectively, and pulse waveforms will be formed on the fluorescent screen. Based on these pulse waveforms, the position and size of the defect can be judged. There are many wave modes when ultrasonic wave propagates in the medium, the most commonly used in inspection are longitudinal wave, transverse wave, surface wave and plate wave. Use longitudinal waves to detect defects such as inclusions, cracks, sh...
