a-
ncurve), need a large amount of tests, experimentation cost is very high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of hot die steel heat fatigue cracking vision inspection apparatus, this device can process rear judgement to hot die steel heat fatigue cracking and identify heat fatigue cracking, crackle geometric parameter is calculated, conveniently obtains
a-
ncurve.
Realizing the technical solution of the utility model is: a kind of hot die steel heat fatigue cracking vision inspection apparatus, is characterized in that: comprise thermal fatigue test apparatus and heat fatigue cracking vision inspection apparatus two parts;
Described thermal fatigue test apparatus comprises High Frequency Solid State power supply, sample, inductive coil, heating cooling and counting controller, spray equipment; Described heating cooling and counting controller is connected with High Frequency Solid State power supply, spray equipment respectively, and simultaneous connection is according to processor; Described High Frequency Solid State power supply connects inductive coil; Described sample is positioned over the heating zone of the inductive coil below spray equipment;
Described heat fatigue cracking vision inspection apparatus comprises illumination camera controller, data processor, LED light source, CCD camera; Described illumination camera controller is connected with LED light source, CCD camera respectively, and is connected to data processor simultaneously.
Described sample is positioned on lifting device, this lifting device by sample lifting in adding thermal potential or detecting position.
Described LED light source, CCD camera are at least two, aim at lifting from different perspectives in the sample of detecting position.
Sight line angle between described CCD camera is preferably 30 degree.
Described data processor is computing machine.
The beneficial effects of the utility model are:
1, to the judged result of surface of test piece crackle without the need to artificial cognition, crack length calculate and
a-
ncurve generates can full automation, so measuring period is shorter, efficiency is higher, also reduces and relies on the technology of operating personnel.
2, dynamic monitoring can be carried out to thermal fatigue course, utilize a small amount of sample just can set up a-N curve, considerably reduce experimentation cost
3, the mode owing to being optical measurement, so be a kind of non-cpntact measurement.
4, simple to operate, use under being convenient to test condition.
