Dimension-variable ring-shaped working flume structure for ultrasonic scanning of large-scale rings

Abstract

The invention discloses a variable-size annular working water tank structure for ultrasonic scanning of a large-scale ring piece. The structure comprises an inner wallboard piece and an outer wallboard piece, the inner wallboard piece and the outer wallboard piece are vertically installed on a bottom plate to define an inner polygonal barrel and an outer polygonal barrel, an annular container space with an opening in the upper portion is formed by the outer side of the polygonal barrel defined by the inner wallboard piece, the inner side of the polygonal barrel defined by the outer wallboard piece and the upper side of the bottom plate, a large annular piece can be placed in the annular container space, water is injected, the large annular piece is immersed in the water, and a water immersion focusing probe is used for conducting flaw detection on the large annular piece. A synchronous structure of the inner wallboard piece is located in the inner side of the polygonal barrel defined by the inner wallboard piece, and a synchronous structure of the outer wall plate is located in the outer side of the polygonal barrel defined by the outer wallboard piece. The surplus space of the working water tank is reduced, the water consumption is reduced, and the water injection efficiency is improved; and meanwhile, the volume size of the annular working water tank is adjustable, and the requirements of liquid (water) immersion ultrasonic flaw detection of large annular pieces with different specifications and size characteristics are met.

Description

technical field [0001] The invention belongs to the technical field of quality detection of large forgings, and in particular relates to a size-variable annular working water tank structure for ultrasonic scanning of large rings. Background technique [0002] Large ring parts (generally greater than 5 meters in diameter) are widely used in aviation, aerospace, energy, transportation and other fields, and these fields have higher requirements for the performance of ring parts. At present, the commonly used technologies for manufacturing large ring parts include ring rolling and so on. Large ring parts include thin-walled rings, special-shaped rings, thick-walled discs, etc. During the forming process, internal defects of the finished parts are often caused by internal defects of the blank material. For special-shaped rings, during the large-deformation high-speed rolling process, the deformation of different parts of the rings is different, and forging cracks are prone to oc...
