Abstract
The utility model discloses a defect simulation and comparison test cube for ultrasonic detection. A test cube is a steel cuboid, wherein the right half of the top surface of the test cube is a detection face; a defect groove inclined to the detection face is formed in the left half of the bottom surface of the test cube and inclined by 30 degrees relative to the bottom surface of the test cube; the cross section of the defect groove is in the shape of a parallelogram; the defect groove comprises a groove bottom, as well as a front groove wall and a rear groove wall which are opposite to each other, and a left groove wall and a right groove wall which are also opposite to each other; the groove bottom is a detected face and is an inwardly concave cambered surface; the left groove wall and the right groove wall are perpendicular to the bottom surface of the test cube; the front groove wall and the rear groove wall are inclined relative to the bottom surface of the test cube. The test cube brings convenience for researching and simulating the static return wave and dynamic flexural wave features of area natural defects, such as hot cracks and reheat cracks of steel forge pieces or weld joints, so that detection personnel can conveniently and quickly be competent with the methods for judging the positions, shapes and sizes of defects in the workpieces, as well as estimation of defect types, and accordingly, the talent training efficiency is greatly improved.
Description
Technical field
The utility model relates to ultrasonic detection technology field, particularly a kind of ultrasound examination defects simulation comparison test block.
Background technology
The ultrasound examination of A type pulse reflection is a kind of important and conventional lossless detection method, with respect to other conventional lossless detection methods, the ultrasound examination of A type pulse reflection requires the highest to individual skill quality, the result detecting is subject to individual level of skill and has the greatest impact, simultaneously the most difficult cultivation be also qualified A type pulse reflection ultrasound examination personnel.
A type pulse reflection ultrasound wave detects in actual mechanical process in reality, need to synchronously complete the evaluation of the detection of workpiece and conclusion, and this just needs testing staff to possess suitable experience.In actual A type pulse reflection ultrasound examination work, operating personnel's experience whether enrich the height that is determining to detect quality.The accumulation of A type pulse reflection ultrasound examination experience is mainly the accumulation of the ultrasonic echo perceptual knowledge that causes of defect (crackle, slag inclusion, pore etc.) possible in type, material, shape and the workpiece to workpiece.And this perceptual knowledge, in real work, is difficult to the high-frequency of the system of having an opportunity touch, thereby need the very long time this perceptual knowledge is accumulated and deepen with raising experience.
The research of ultrasonic detection comparison test block is mainly the research that flaw size equivalent proportion is right at present, if the patent No. is a kind of ultrasonic detection comparison test block of " 201120223298.4 ".Described in this patent, test block is steel rectangular parallelepiped, is equidistantly drilled with the flat-bottom hole of at least 5 different depths in test block bottom, and the flat-bottom hole degree of depth takes regular echelon to arrange by a side direction opposite side.When ultrasound examination instrument probe touches in test block after certain flat-bottom hole, on screen, will demonstrate Defect Equivalent and the degree of depth of this hole site, by the data and the situation comparison that will measure defect of this method reflection, just can accurately understand the concrete degree of depth of defect and the Defect Equivalent of detecting element.But this class comparison test block cannot allow testing staff have a perceptual understanding to the typical echo curve of defect and dynamic waveform envelope.
Some units collects the natural flaw of scrapping on member and is processed into test block research in addition, but defective locations, shape, size, the type in test block is all difficult to know in advance in this case, and defect collection difficulty is also very large.
Utility model content
The utility model has overcome above-mentioned the deficiencies in the prior art, a kind of ultrasound examination defects simulation comparison test block is provided, this test block can facilitate research simulation steel forgings or the fire check of weld seam and the bent wave characteristic of the echo Static and dynamic of reheat crack(ing) homalographic type natural flaw in laboratory, be convenient to testing staff and grasp fast the method for defective locations, shape, size in this type of workpiece of judgement and estimate the ability of sentencing defect type, the efficiency of personnel training is significantly improved.
The technical solution of the utility model is achieved in that
A kind of ultrasound examination defects simulation comparison test block, described test block is steel rectangular parallelepiped, the right half part of test block end face is detection faces, left-half in test block bottom surface offers towards the defect groove of detection faces direction inclination, described defect groove is 30 degree with respect to the angle of test block inclined bottom surface, the xsect of defect groove is parallelogram, described defect groove comprise bottom land and be oppositely arranged before, rear cell wall is with left, right cell wall, bottom land is for being subject to inspection face, bottom land is the cambered surface of indent, left, right cell wall is perpendicular to test block bottom surface, before, rear cell wall is with respect to test block inclined bottom surface.Defect groove is 30 degree with respect to the angle of test block inclined bottom surface, and the inclination angle design of 30 degree can be avoided because next a large amount of careless shape clutter is worn by the cell wall Deng Fei research circle of defect groove for the incident angle of at present conventional compressional wave oblique incidence ultrasonic probe.
Adopted principle of the present utility model and the beneficial effect of technique scheme to be:
The utility model, owing to having adopted technique scheme, can allow ultrasound examination personnel in shorter time, accumulate enough practical experiences, becomes a ripe testing staff and has greatly improved the efficiency of personnel training; The angle that defect groove tilts is the processing technology thereof standardization that the design of 30 degree both can make test block, can make again the detected face of artificial slot be positioned at the orientation that is conducive to examinations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model in embodiment.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: a kind of ultrasound examination defects simulation comparison test block, as shown in Figure 1, described test block 1 is steel rectangular parallelepiped, the right half part of test block end face is detection faces 2, ultrasonic probe 8 moves in detection faces 2, left-half in test block bottom surface 4 offers towards the defect groove 3 of detection faces 2 directions inclinations, and the angle that described defect groove 3 tilts with respect to test block bottom surface 4 is 30 degree.
The xsect of defect groove 3 is parallelogram, described defect groove 3 comprises bottom land 5 and the forward and backward cell wall 6a, the 6b that are oppositely arranged and left and right cell wall 7a, 7b, bottom land 5 is for being subject to inspection face, and the cambered surface that bottom land 5 is indent, left and right cell wall 7a, 7b are perpendicular to test block bottom surface 4, and the angle that forward and backward cell wall 6a, 6b tilt and tilt with respect to test block bottom surface 4 is 30 degree.
The present embodiment is mainly simulated fire check and the reheat crack(ing) homalographic type natural flaw of steel forgings or weld seam, and defect groove is examined the radian of face and can be selected as requested.Through Ultrasonic Detection echo curve signature analysis, its detection of echoes static curve is identical with performance graph and similar natural flaw echo character.
