Description
Technical field
The present invention relates to a kind of technical field of laser processing, laser temperature pill spraying surface reinforcing field particularly, silicone oil restraint device and the method thereof at the uniform velocity continuously specifically in a kind of laser peening strengthening process, used.
Background technology
Laser temperature shot-peening, is a kind of novel surface strengthening treatment technology, can reach the surface strengthening effect better than mechanic shot peening.The surge pressure of induced with laser generally need to just can reach good shot blasting effect by the constraint of restraint layer.The most frequently used restraint layer of room temperature laser peening is flowing water, but flowing water can produce even vaporization of bubble at higher temperature, so the conventional flowing water restraint layer of laser peening can not be for laser temperature shot-peening.The surge pressure that how effectively to retrain induced with laser at higher temperature has become the focal issue of mechanical association area.The conventional constrained procedure of laser peening has flexible constraint and rigid constraint at present.
Flexible constraint, is mainly that the pressure that utilizes flexible media to produce laser peening retrains, and comprises flowing water constraint, high pressure gas constraint and flexible lamina constraint.Flowing water constraint, is at matrix surface, to manufacture the flowing water layer of one deck 1 ~ 5mm, utilizes flowing water layer percussion pressure to retrain.The patent application that for example patent No. is CN102212655A, a kind of laser shock method has been proposed, in laser-impact process, use moisture film as restraint layer, this constrained procedure can play to induced with laser pressure the effect of constraint at normal temperatures, but flowing water restraint layer is because lower boiling point is not suitable for the occasion that temperature is higher.Flexible lamina, to paste the flexible materials realization constraint with binding effect at matrix surface, the patent application that for example patent No. is CN1404954A, a kind of flexible lamina of processing for laser-impact has been proposed, the method utilizes silicon gel material to be made into flexible lamina, cover matrix surface and realize constraint, but there is following some deficiency: (1) silicon gel material at high temperature melts as liquid state, in laminating process, between pad pasting and matrix, be easy to enter air, so dissolve rear formation bubble, reduce binding effect; (2) laser-impact process applying plasma extreme temperatures, silicon gel material easily burns, and reduces binding effect, and security is not high.Gas constraint, to utilize high pressure that gas produces at material surface as constraint, the patent application that for example patent No. is CN102560079A, this patent application has proposed a kind of laser shock peening method and device thereof that high pressure gas are restraint layer of take, the method is to adopt high pressure gas continuous injection to matrix surface, induced with laser surge pressure is retrained, this method can play the effect of constraint at normal temperatures, but also there is following shortcoming: (1) high pressure gas is known from experience affects plasma body in the cohesion of matrix surface, reduce induced with laser surge pressure; (2) high pressure gas is known from experience the temperature that obviously reduces matrix surface continuously, thereby the method is not suitable for the occasion of laser temperature shot-peening.
Rigid constraint, is mainly by rigidity transparent medium, induced with laser pressure to be retrained, and is mainly glass at present, for example K9 glass.The patent application that for example patent No. is CN102492805A, a kind of method and apparatus that adopts the laser impact intensified metallic substance of deep cooling has been proposed, the method adopts K9 glass as restraint layer, induced with laser pressure to be retrained in laser-impact process, although this method can play binding effect under normal temperature and low temperature, but also there is following shortcoming: the surge pressure that (1) produces due to induced with laser is easily at generation stress concentration on glass, thereby cause on glass cracking even to be broken, reduce shot blasting effect; (2) K9 glass at high temperature can produce softening effect, more easily cracks even fracture, thereby causes the effect of shot-peening to reduce.
What relatively approach with the present invention is the patent No. patent application that is CN103143836A, in this patent application, utilize the flowable liquids of pump housing conveying as restraint layer, this method goes for the laser peening under normal temperature, but for laser temperature shot-peening, resistant to elevated temperatures transparent liquid is less, as conventional silicone oil, owing to thering is high viscosity, general vane pump is difficult to realize it to be carried, and high-power ram pump is expensive and adjust difficulty, is difficult to meet the production requirement of variant production.
