The invention relates to large-format selective laser melting (SLM) equipment of a multi- galvanometer, which comprises an SLM forming table, wherein the SLM forming table is divided into four uniform forming areas, respective separate galvanometer systems are respectively arranged above the forming areas, galvanometer components in all of the galvanometer systems are respectively in control connection with respective corresponding galvanometer motion controllers, all of the galvanometer motion controllers are in control connection with a central controller, so as to form parts which cannot be manufactured by the traditional SLM equipment, and additionally, the processing efficiency of the parts is increased.
Description
Technical field
The present invention relates to the rapid shaping technique field, particularly a kind of many galvanometers large format selective laser melting SLM equipment.
Background technology
Selective laser melting SLM is a kind of method of metalwork straight forming, is the latest development of rapid shaping technique.This technology is based on the basic thought of rapid shaping, i.e. " increment " manufacture of successively cladding, and according to the part that the three-dimensional CAD model straight forming has geometry in particular, metal dust melts fully in the forming process, produces metallurgical binding.Adopting the metal parts that traditional machined means can't produced shape and structure complexity, is one of main direction of using of rapid laser-shaping technique.Have the following advantages:
(1) can directly make the terminal metal product, need not any aftertreatment technology or simple surface treatment, select directly to process the part that can directly use by simple CAD moulding and material, greatly shortened product development cycle;
(2) can obtain having the entity of nonequilibrium state supersaturated solid solution and even tiny metallographic structure, density almost can reach 100%, and the part machinery performance is suitable with the Forging Technology gained;
(3) use the laser instrument with high power density, with the very little laser beam processing metal of hot spot, so that the metal parts that processes has very high dimensional accuracy (reaching 0.1mm) and good surface roughness (Ra 30～50 μ m);
(4) because laser spot diameter is very little, therefore can melt with lower power dystectic metal, so that come finished parts to become possibility with the metal dust of single component, and also the metal dust kind that can Gong select has also been expanded greatly;
(5) be fit to the workpiece of various complicated shapes, especially being fit to inside has the complicated abnormal shape structure, such as cavity, three-dimensional grid and the complex part that can't make with conventional method.
But the shaped region of existing selective laser melting SLM former is 250mm * 250mm to the maximum, and the size restrictions of shaping sample is larger, has also limited selective laser melting SLM equipment applying in industrial quarters simultaneously.And the laser cladding equipment of large format has larger forming dimension, but its forming accuracy is relatively poor, need to make the secondary machine and add just and can come into operation, and has virtually increased process time and the cost of part.
Summary of the invention
The invention provides a kind of many galvanometers large format selective laser melting SLM equipment, comprise selective laser melting SLM shaping table top, this selective laser melting SLM shaping table top is divided into uniform four shaped regions, each shaped region top is provided with separately independently galvanometer system, galvanometer parts in each galvanometer system connect with each self-corresponding galvanometer motion controller phase control respectively, and all galvanometer motion controllers all connect with the central controller phase control.Avoid forming accuracy relatively poor, need to make the secondary machine and add just and can come into operation, virtually increased the process time of part and the defective of cost.Thereby the part that traditional SLM equipment that can be shaped can't be made has improved the working (machining) efficiency of part simultaneously.
For achieving the above object, technical scheme of the present invention is:
A kind of many galvanometers large format selective laser melting SLM equipment, comprise selective laser melting SLM shaping table top 6, this selective laser melting SLM shaping table top 6 is divided into uniform four shaped regions, each shaped region top is provided with separately independently galvanometer system, galvanometer parts in each galvanometer system connect with each self-corresponding galvanometer motion controller 5 phase control respectively, and all galvanometer motion controllers 5 all connect with central controller 7 phase controls.
Described galvanometer system comprises X-axis galvanometer 1 and the Y-axis galvanometer 2 that arranges according to laser beam 4 incident directions separately, and X-axis galvanometer 1 and Y-axis galvanometer 2 have consisted of described galvanometer parts, is provided with flat field condenser lens 3 in the laser beam exit direction of galvanometer parts.
By under galvanometer motion controller 5 the synchronized Coordinative Control of 7 pairs four of central controllers, laser beam is by four shaped regions top each self-corresponding X-axis galvanometer 1 and Y-axis galvanometers 2, and finishes scanning motion at shaped region separately at last through each self-corresponding flat field condenser lens 3.This selective laser melting SLM former scheme adopts 4 galvanometer parts to work simultaneously, the shaped region area of plane is four times of common selective laser melting SLM equipment, working (machining) efficiency also is four times of common selective laser melting SLM equipment, can adapt to the shaping demand of large-scale part.Control system can the auto Segmentation shaped region, with 4 shaped region collaborative works, has improved the structural strength of drip molding.
