Description
Technical field
The utility model relates to a kind of laser melting coating manufacturing, is specifically related to a kind of laser melting coating fast precise manufacturing installation based on laser milling.
Background technology
Laser melting coating is made, and is meant the laser processing straight forming of metal parts, during this technology adopts, the metal-powder supplied with synchronously of high power laser fusing, on deposition substrate, successively piles up and forms metal parts.This technological breakthrough traditional diamond-making technique remove the notion of moulding, adopt the method forming part that adds material, do not have the waste of material problem; Accessible material very extensively is specially adapted to the material that traditional method is difficult to moulding; Do not have interference during moulding between instrument and the workpiece, the geometrical shape of part is restricted hardly; Need not any mould during moulding, can significantly shorten the part manufacturing cycle, strengthen the product competition advantage, be particularly conducive to the production of complicated shape, multi-varieties and small-batch part; Institute's forming part density is high, has rapid solidification tissue signature, can satisfy directly to be suitable for requirement, in the preparation of space flight device, flight engine part and weapon part, has broad application prospects; Can prepare the part that FGM and different sites are made up of differing materials very easily through changing over type material in addition.Therefore, the preparation of high quality and low cost, shaping, the accurate manufacturing technology of the incorporate short flow process laser melting coating of processing have become the important development direction of advanced manufacturing technology.
Existing laser cladding forming part generally all adopts does not have the forming technique of support; Because supporting condition lacks; Profiled member mostly is straight wall or small inclination spare, and the complicated shape part at big skew back or outstanding angle possibly trickle even cave in moulding process because of gravity causes, and secondly laser melting coating manufacturing is as range upon range of adding type manufacturing processed; The pattern of each cladding layer is to be determined jointly by a plurality of processing parameters such as laser power, sweep velocity, powder feed rate, beam diameter, molten road and interlayer overlapping rates; Issuable disturbance in the unstable of any one factor or the range upon range of working cycle, all can cause cladding layer occur uneven with hang slag, if these uneven with hang that slag is untimely effectively to be disposed; Then cause manufacturing processed uncontrollable situation to occur easily, cause last difficult forming.
In order to guarantee that the laser melting coating manufacturing processed can continue to carry out; And reach required size of industrial applications and surface accuracy; Some technician utilize closed loop control system, and through online detection part height, thereby processing parameters such as regulating mechanism laser power, sweep velocity, powder feed rate are eliminated the uneven and extension slag that occurs in the forming parts process; But because inevitably there is hysteresis quality in system, thereby can not realize processing purpose fully.Some technician is through carrying out finished machined to part in moulding process with after the moulding completion; Yet the metal parts of straight forming increases because of quench solidification makes surface hardness, causes very difficulty of post-production; Complex-shaped part also needs anchor clamps to cooperate multiple clamping sometimes; Cause process period longer, even will account for more than 60% of whole manufacturing cycle, thereby limited the short flow process of laser melting coating finished parts, manufacturing, high-precision development fast greatly.
Summary of the invention
