Description
Technical field
The present invention relates to mechanical manufacturing field, refer in particular to a kind of laser-impact accurate forming method and device, it is applicable to the high efficiency of large-scale metal blank, complicated precision form, the fine structure that also is applicable to metal blank is shaped, be particularly suitable for conventional method and be difficult to the material forming that is shaped or can't be shaped at all, as titanium alloy, magnesium alloy materials etc.
Background technology
The metal blank Plastic Forming is processed main method as sheet material forming, has occupied crucial status in whole national economy, is widely used in production industries such as Aero-Space, shipping industry, automobile panel, electronics, instrument.At present, it is a lot of to be used for the sheet metal plastic molding method both at home and abroad, comprises punching press, explosive forming, contour peening, laser thermal stress shaping and laser impact forming etc.Traditional mould drawing is that sheet metal is placed on the mould, under the forcing press effect, at the inner internal force that makes it to be out of shape that produces of sheet material, when the effect of internal force acquires a certain degree, just obtain the part of certain shape, though simple to operate, the production efficiency height, it is long to produce time, processing flexibility is poor, die cost is big, the high deficiency of manufacturing cost, and the mold cold drawing is only applicable to mild-steel sheet (as 10F, 20,1Cr18Ni9Ti etc.), the good materials of plasticity such as aluminium alloy (as LY12M, LY12C etc.) and copper, but limited by forming limit.
Patent " the CONTOUR FORMIMG OFMETALS BY LASER PEENING " patent No.: the WO0105549 that HACKEL LLOYD of California, USA university and HARRIS FRITZ application is arranged by retrieval, this patent proposes to produce residual stress with laser hammering sheet metal surface, utilize residual stress to discharge again and produce little distortion shaping that little curvature is carried out, the accumulation of the little curvature by the each hammering of each point or implement repeatedly to impact in same point just can obtain larger sized bending.Its shortcoming is as follows: (1) is owing to being to utilize the strain that residual compressive stress takes place to produce bending, so deflection is little; (2) stress distribution that produces by the pointwise hammering is controlled large-area bending, and this is very difficult in actual applications; (3) moulding material and technology are single, are bending forming and rod member school shape to the metal material hammering.
The patent of invention " a kind of laser-impact accurate forming method and device " of people such as the domestic Zhang Yongkang of Jiangsu University application, license number: 01134063.0, this patent adopts high-performance laser-impact Precision Forming Technology, it directly utilizes the intense pulse laser bundle to impact the flexible lamina of surface of the work, make its top layer gasification ionization and form shock wave, because the shock wave pressure peak value that produces surpasses the MATERIALS ' DYNAMIC yield strength, this makes moulding material that obvious plastic deformation take place.This patent of invention provides a good idea for metal sheet profiled.Its shortcoming is as follows: (1) its in the laser impact forming process, the each amount of plastic deformation of plate is little, for high strength alloy steel with than heavy-gauge sheeting, deflection is littler, mainly is applicable to the shaping of thin plate.(2) because the each amount of plastic deformation of plate is little, lower for large-area forming efficiency; Large-area shaping aspect only depends on each generation plastic deformation to finish forming process, can produce the inhomogeneities between distortion, so surface flatness is affected.(3) because the impact forging process, the influence of factor such as the isoparametric fluctuation of laser energy can take place inevitably, produce the shaping amount such as problem such as excessive can't be revised.(4) because the reason of (3), also be difficult to finish the impact forging of complex part, carry out also unusual difficulty of precision form.(5) the difficult requirement of finishing large complicated precision workpiece shaping of its device.
