Abstract
The utility model provides an inspection block of RB type. The structure of the inspection block is a culoid with the length less than 680mm, the width less than 375mm and the depth less than 60mm. A different amount of holes are arranged vertically in the middle of the inspection block. According to the need, curvatures which are normally smaller than 80mm are arranged on the upside and downside. Compared with the present technology, the utility model has the advantages of reasonable design, simple structure, high manufacture accuracy, wide testing scope and convenient use so that the utility model has very good promoting value in damage-free inspecting industry.
Description
1, technical field
The utility model relates to UT (Ultrasonic Testing) test block process technology, specifically a kind of RB class flaw detection test block.
2, background technology
At present, it is a lot of to be used for the test block kind that ultrasonic investigation uses, ubiquitous when not enough measuring accuracy not high, need repeated measurement, thereby strengthened tester's workload.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of measuring accuracy higher relatively RB class flaw detection test block.
The technical solution of the utility model is, test block is to be made of test block body and perforate, and the test block body is a length≤680mm, and is wide≤375mm, the rectangular parallelepiped of height≤60mm; Intermediate vertical at the test block body is drilled with the perforate that quantity does not wait, and upper and lower surfaces are provided with curvature, and radius-of-curvature is general≤80mm.
The utility model has the advantages that:
1) measures shear wave distance-amplitude curve;
2) the K value of inclino-probe;
3) adjust the shear wave sweep velocity;
4) adjust sensitivity;
4, description of drawings
Accompanying drawing 1 is the main TV structure synoptic diagram of RB class flaw detection test block;
Accompanying drawing 2 is plan structure synoptic diagram of RB class flaw detection test block;
Accompanying drawing 3 is the RB class flaw detection test block structural representations that have through hole.
Mark in the accompanying drawing is represented respectively; Test block body 1; Perforate 2; The face 3 of carving characters.
5, embodiment
Below in conjunction with accompanying drawing following detailed description the in detail done in RB class flaw detection test block of the present utility model.
As shown in drawings, RB class flaw detection test block of the present utility model, test block is to be made of test block body 1 and perforate 2, test block body 1 is a length≤680mm, and is wide≤375mm, the rectangular parallelepiped of height≤60mm; Intermediate vertical at test block body 1 is drilled with the perforate that quantity does not wait, and upper and lower surfaces are provided with curvature, and radius-of-curvature is general≤80mm.
Perforate 2 in the middle of the test block body 1 is blind hole or through hole.
The upper surface of test block body is the face of carving characters 3.The content of carving characters comprises test block title, trade mark, standard No., manufacturing numbering and manufacturing firm.The model of this test block can have following 16 kinds:
RB-1 CTRB-3
RB-2 DB-H1
RB-3 DB-H2
CSK-IIA GS test block
CSK-IIIA JIS-STB-A2
CSK-IVA RB-4
CTRB-1 WGT-2
CTRB-2 WGT-3
The purposes of RB class flaw detection test block of the present utility model is:
1) measures shear wave distance-amplitude curve;
2) the K value of inclino-probe;
3) adjust the shear wave sweep velocity;
4) adjust sensitivity;
Be compared with existing technology, have reasonable in design, simple in structure, easy to use, test specification is wide, can Test probe again can tester etc. characteristics, thereby, have good value for applications.
