Description
Technical field
The present invention relates to a kind of bar ultrasound automatic detection flat-bottom hole reference block and preparation method, belong to Non-Destructive Testing
Technical field.
Background technology
In being detected to bar forging automatic ultrasonic, due to workpiece own specifications and detection and acceptance criteria requirement, for not
Same depth bounds allows the equivalent size of existing defects also different.Current bar ultrasound automatic detection can only be using automatic inspection
Instrument discovery defect is surveyed, scene cannot compare qualitative deficiency degree.To compare qualitative deficiency degree, also need using portable
Formula instrument, could complete to compare qualitative deficiency degree by single reference block.
The content of the invention
When carrying out automatic ultrasonic detection it is an object of the invention to provide a kind of bar, the same of bar material defect is being detected
When, so that it may compare a kind of ultrasound automatic detection flat-bottom hole reference block of bar and preparation method for quantifying defect level.
Technical solution
A kind of bar ultrasound automatic detection flat-bottom hole reference block, comprising test block body, in test block body and central shaft
At least provided with a flat-bottom hole at least one parallel parallel lines of line, with flat-bottom hole aperture corresponding section on test block body surface
It is provided with the scale of value with a scale.
A kind of bar ultrasound automatic detection preparation method of flat-bottom hole reference block, method is as follows：
Step 1) test block body is cut into at least two parts test block along the parallel of test block body central axis,
Step 2) at least one flat-bottom hole is had on tangent plane in test block body；
Step 3) by perforate after at least two parts test block test block docking, then joint surrounding using welding manner will
Integral test block is welded at least two parts test block again, and the scale of value with a scale is provided with the commissure of overall test block.
When the test block body is with diameter greater than 300mm, the integral examination two ends after welding are respectively equipped with clip.
Advantages of the present invention is as follows：
1st, multiple flat-bottom hole artificial defects of different depth and equivalent can be made in test block as needed, for bar
The detection demand of different acceptance criterias and products of different specifications, it is applied widely；
2nd, multiple flat hole sites are marked in test block end face vertical direction and scanning face horizontal slice binding site in test block
Bright position, and all directions position marks scale, the selection of artificial defect when being easy to detect；
3rd, flat-bottom hole reference block can be directly used for the judgement to finding defect in ultrasonic automatic detection；
4th, the reference block of bar automatic ultrasonic detection has good versatility.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Test block body 1 of the present invention uses partitioned organization, and preparation method is as follows：

Step 2) by step 1) at least to have at least one on the center line by tangent plane of two parts test block flat
Hole 2；
Step 3) by perforate after the test block of at least two parts docking, then will at least using welding manner in joint surrounding
Integral test block is welded in two parts test block again, and the scale 5 of value with a scale is provided with the weld seam 4 of overall test block.
The present invention for test block body 1 with diameter greater than 300mm when, in addition it is also necessary to after welding overall test block two ends difference
It is provided with clip 3.
Embodiment 1
Test block body 1 is cut into three parts on present invention edge and two parallel lines of the centerline axis parallel of test block body 1
Test block,
Step 2) in step 1) in cut three part test blocks, one is provided with center line of the top test block by tangent plane
Flat-bottom hole 2；Bottom test block is provided with two flat-bottom holes 2 on the center line of tangent plane；
Step 3) test block of perforate upper back and bottom test block are docked with middle part test block again respectively, combine integral again,
Then three part test blocks are welded by integral test block using welding manner again in joint surrounding, at the weld seam 4 of overall test block
It is provided with the scale 5 of value with a scale.
The present invention for test block body 1 with diameter greater than 300mm when, in addition it is also necessary to after welding overall test block two ends difference
It is provided with clip 3.
The present invention for bar ultrasound automatic detection reference block, according to acceptance criteria on reference block each subregion
It is required that the flat-bottom hole of processing different depth and different equivalent sizes, and in reference block end face to the depth and equivalent of artificial defect
Size is labeled.During detection, the artificial defect of different depth and equivalent is chosen in automatic tester according to acceptance criteria requirement
Sensitivity is adjusted on device, to finding that the gain of defect and wave height are compared with artificial defect in scanning, it is determined whether meet and test
Receipts standard.
