Abstract

The invention relates to a model rod for bar automatic-rotation supersonic wave detection. The model rod comprises a cylindrical rod, the upper end of a side of the rod is provided with a blind hole, the middle of the rod in the rear of the blind hole is provided with a central cross bore, the rear side of the central cross bore is provided with a surface short shallow groove on the upper surface of the rod, the rear side of the surface short shallow groove is provided with a subskin cross bore which is located on the upper surface of the rod, the rear side of the subskin cross bore is provided with a surface long deep groove located on the upper surface, the rear side of the surface long deep groove is provided with a central cross bore located at the middle of the rod, the rear end of the central cross bore is provided with a cross bore close to the surface which is located at the lower part of the rod, and a part close to the rear end of the rod is provided with a central cross bore located at the middle of the rod. The model rod has the characteristics of a normative shape, reasonable man made destroy arrangement, clear identification, simple structure, comprehensive functions, operation easiness, accurate verification, safety, practicability and no maintenance.

Description

technical field [0001] The invention belongs to the technical field of metallurgical product quality detection, and relates to a sample rod for automatic rotating ultrasonic detection of rods and a use method thereof. Background technique [0002] Water immersion automatic rotary ultrasonic testing is an efficient and accurate internal quality testing process for round bars. The process testing equipment includes automatic ultrasonic testing equipment, sample bars for equipment verification, supporting bar conveying platforms, loading and unloading rollers and Sorting agency. The inspection procedure is: according to the specifications and quality requirements of the rods to be inspected, the reference sample rods are used to calibrate the detection equipment (including probe calibration and sensitivity setting), and then the automatic detection of the rods through the rods is carried out. Among them, the reference sample rod for equipment debugging is the key reference par...
