Description
Technical field
The invention belongs to increases material manufacturing technology field, and in particular to a kind of many galvanometers that can improve clarifying smoke effect are significantly
Face selective laser fusing equipment.
Background technology
Selective laser fusing is a kind of increases material manufacturing technology, and it uses galvanometer system to export high energy density laser beam, right
The metal powder layer for successively laying implements selective melting, and then completes the shaping of metallic element.Have benefited from above-mentioned operation principle,
Selective laser smelting technology has the series of advantages such as flexibility degree is high, properties of product are excellent, adaptability for materials is extensive, and can
Shaping conventional machining means are difficult to the labyrinth metal product for manufacturing.
In the selective laser smelting technology early stage of development, the selective melting of metal dust is generally only by shaking that a set of position is fixed
Mirror system is completed, and causes forming efficiency relatively relatively low, strongly limit the shaping breadth of equipment and the size of formable part.For
Make up the deficiency, team where inventor grind and propose " many galvanometer selective lasers melting method (CN102266942A,
CN104001915A) ", its basic ideas can be summarized by Fig. 1：Many set galvanometer systems are introduced in selective laser fusing equipment, and
Row arrangement is pressed, galvanometer combination is constituted；During Prototyping Metal Parts, synchronous sweeping is implemented in the combination of control galvanometer to metal powder layer
Retouch；If the effective irradiation region of galvanometer combination can not cover whole metal powder layer, first control galvanometer combination effective to its
Metal powder layer in irradiation zone implements synchronous scanning, then galvanometer combination is moved on the metal powder layer for not yet scanning
Side, final election area fusion process of laying equal stress on, until completing the selective melting of whole metal powder layer.By the above method, selective laser
The processing efficiency of smelting technology is obviously improved, and team where inventor and domestic and international other mechanisms also have developed one in succession
The many galvanometer big width laser selective melting equipments of series, metal powder layer lays the length and width and the three of formable metal parts of breadth
Dimension size has moved closer to even up to " rice " level.
It must be pointed out that in the fusion process of selective laser, metal powder layer top can be inevitably generated a large amount of
Flue dust.Only in time by clarifying smoke, the constant of incident laser beam energy density could be maintained and the clean and tidy of nacelle that work, and then
Ensure the stability of forming process.Therefore, the conventional laser selective melting equipment being either made up of a set of galvanometer system, or
New many galvanometer big width laser selective meltings equipment, its shaped region typically all passes through bleeding point, air taking port and contains to follow
The clarifying smoke main frame connection of ring blower fan and porous filter medium/liquid filtration media.During part forming, clarifying smoke
Host computer circulating fan by metal powder layer top the gas containing flue dust from bleeding point extract out, by porous filter medium/
After liquid filtration media is by filtrating smoke dust, then the gas without flue dust is re-fed into metal powder layer top via air taking port.
However, as shown in figure 1, generally only one group of the bleeding point of existing many galvanometer big width laser selective meltings equipment and air taking port,
And it is individually fixed in the front and rear both sides of metal powder layer.When Prototyping Metal Parts, position is fixed, bleeding point apart from each other with
Air taking port cannot generally produce stabilization, uniform air-flow above the larger metal powder layer of breadth so that clarifying smoke effect
Not satisfactory, thus caused shaping failure or product quality deteriorate case and emerge in an endless stream.
