Abstract
The utility model relates to a fold defect reference block, and belongs to the technical field of ultrasonic flaw detection. The fold defect reference block comprises a reference block body (1), wherein the reference block body (1) is made of glass reinforced plastic, three arc-shaped grooves (2) which are parallel are formed in the bottom of the reference block body (1), and the diameters of the three arc-shaped grooves (2) gradually increase in sequence from left to right. The fold defect reference block is reasonable in structure and exquisite in design, and can be applied to ultrasonic detection of blades of wind driven generators.
Description
Technical field
The utility model relates to a kind of ultrasonic flaw detection briquette, specifically relates to a kind of wrinkle defect reference block, belongs to UT (Ultrasonic Testing) technical field.
Background technology
UT (Ultrasonic Testing) is to utilize ultrasonic energy to penetrate the depths of metal material, and while entering another cross section by a cross section, the feature that occurs to reflect in interface edge checks a kind of method of part defect, when ultrasonic beam passes to metal inside from piece surface by probe, while running into defect and part bottom surface, just there is respectively reflection wave, on video screen, form pulse waveform, according to these pulse waveforms, judge defective locations and size.But UT (Ultrasonic Testing) technology is applied in conventionally in the Non-Destructive Testing of metal (especially steel and products thereof) at present, also not for glass fiber reinforced plastics composite material, particularly be applied in the ultrasonic detection method on blade of wind-driven generator (fiberglass parts), also there is no corresponding calibration block.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of wrinkle defect reference block is provided, and it can be applied to the ultrasound examination of blade of wind-driven generator.
The purpose of this utility model is achieved in that a kind of wrinkle defect reference block, it comprises test block body, described test block body is made by fiberglass, and described test block body bottom offers three parallel deep-slotted chip breakers, and described three deep-slotted chip breakers from left to right diameter increase successively.
Described test block body is rectangular parallelepiped, and described test block body is of a size of 200mm * 60mm * 35mm.
The diameter of described three deep-slotted chip breakers is followed successively by 10mm, 20mm, 30mm.
Compared with prior art, the utlity model has following beneficial effect:
A kind of wrinkle defect reference block of the utility model, it is rational in infrastructure, designs ingeniously, can be applied to the calibration block in power-driven generator leaf ultrasound examination.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of wrinkle defect reference block of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Wherein:
Test block body 1
Deep-slotted chip breaker 2.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of wrinkle defect reference block of the utility model, it comprises test block body 1, described test block body 1 is rectangular parallelepiped, described test block body 1 is of a size of 200mm * 60mm * 35mm, and described test block body 1 is made by fiberglass, and described test block body 1 bottom offers three parallel deep-slotted chip breakers 2, described three deep-slotted chip breakers 2 from left to right diameter increase successively, and the diameter of described three deep-slotted chip breakers 2 is followed successively by 10mm, 20mm, 30mm.
The utility model is mainly for detection of whether having wrinkle defect in aerogenerator fiberglass blade and determining its depth and place.
