Description
Technical field
It is flat with operation that the utility model is related to the recyclable laser melting coating of a kind of adjustable elevation angle, temperature-controllable, waste material
Table apparatus.
Background technology
Laser melting and coating technique is a kind of new surface risen with the development of high power laser 1970s
Modification technology, this technology is that alloy powder or ceramic powders with matrix surface are heated and melted rapidly under laser beam effect,
With method of the matrix material in a kind of rapid shaping of the face coat of metallurgical binding.Using laser melting and coating technique, it can obtain
The higher functor of arbitrarily complicated shape, good mechanical properties, dimensional accuracy, is adapted in small lot, the sophisticated functions customized
Applied on part.
Laser cladding forming technology is in automobile, the processing and manufacturing of Aero-Space strength member, maintenance, the life of Complex Different Shape part
Production, the rapid mold manufacture in research and development, have for fields such as the research and development manufactures of high-precision end weapon in military enterprise and widely should
With.
Compared with other surfaces reinforcement technique, the advantage of laser melting coating has：
(1) cooling velocity is fast, and laser melting coating belongs to rapid solidification, is readily obtained fine grained texture or produces equilibrium state institute
The cenotype that can not be obtained, such as non-steady phase, amorphous state；
(2) coating dilution rate is low, is combined with matrix in firm metallurgical binding or interface extension, by joining to laser technology
Several adjustment, can obtain the good coat of low dilution rate, and coating composition and dilution factor are controllable；
(3) heat input and distortion are smaller, during in particular by high power density quick cladding, and deformation can be reduced to part
In build-up tolerance；
(4) powder selection is almost without any limitation, particularly in low-melting-point metal surface cladding high-melting-point alloy；
(5) thickness range of cladding layer is big；
(6) constituency cladding can be carried out, material consumption is few, with remarkable cost performance；
(7) technical process is simple, it is easy to accomplish automation.
In laser cladding process, powder sprays through coaxial powder-feeding nozzle is sent to matrix surface, by absorbing laser energy
Fusing absorbs energy fusing with substrate and is collectively forming molten bath, and the scanning pattern that nozzle is controlled according to computer is run, and powder feeder is sent
Powder absorption luminous energy up to substrate surface constantly melts, then rapid solidification, so as to realize shaping manufacture, surface reconditioning etc..
In whole process, there are following several defects：
1. the workbench of cladding is irremovable during cladding, only by the position of mobile laser head to find
The origin position that cladding is started working, this regulation operation needs to adjust the position of laser head, it is necessary to meat by the handle of robot
Eye homing position and then progress origin calibration, if misoperation can cause laser head to strike process operation plane, damage and swash
Shaven head.Further, since the limitation of equipment, such as need cladding from the horizontal by certain angle workpiece when, because no support is set
Standby, this cladding operating process will be unable to carry out；
2. the temperature of laser melting coating is generally 1000 DEG C or so, when the number of plies of cladding is less, temperature sink is very fast, with
Thickness gradually increases, and temperature heat build-up phenomenon is also gradually seriously got up, and then cause the temperature and heat heap of workpiece top
Product is higher, and " collapsing " phenomenon occurs during cladding, influences molding effect；
3. when powder sending quantity and sweep speed reach certain value, the powder speed that laser head sprays is very fast, powder amount compares again
It is larger, the phenomenon of powder " splashing " at this moment just occurs, the powder that " splashing " goes out can not be collected again, and powder is largely unrestrained
Take.
