Abstract
The present invention relates to a kind of laser formation machines, it includes rack 1, feeding system 2, powdering hopper and kinematic system 3, blanking Material collecting box for harvesting, molding cylinder barrel and moulding cylinder piston motion drive system, and the optical system being made of laser, scanning galvanometer, reflection and focus lamp, it is characterised in that molding cylinder barrel is the scalable cylinder barrel of no less than two sections.Due to using telescopic moulding cylinder cylinder barrel, it thus may be implemented in the case of not increasing work top height and device height, increase the impulse stroke of molding the cylinder piston, to realize increasing processing part size, improve the operability and reliability of equipment.
Description
Technical field
The present invention relates to a kind of laser formation machines, specifically, are related to a kind of constituency selective laser sintering molding equipment, belong to
Increases material manufacturing technology field scope.
Background technique
Currently, 3D printing has been widely recognized and has applied, constituency selective laser sintering is one of 3D printing technique
Molding mode.The existing powder sintered molding machine of precinct laser mainly issues laser by laser, is expanded and is reflected with scanning galvanometer
It focuses in forming surface, selective laser sintering curing molding is carried out to part section, then form the cylinder piston and decline one layer, weight
As soon as being newly paved with a layer powder, part is completed the process by successively laser sintered solidification in this way, as production part size increases,
It not only requires moulding cylinder cross dimensions to increase, but also requires moulding cylinder piston stroke bigger, existing piston driving method has two
Kind, one is the electric pushrod drivings by being mounted below piston, and when this mode piston stroke is larger, this will lead to forming surface
Height is very high, and equipment is very high, inconvenient；Second is the driving of side lead screw, is may be implemented in this way when piston stroke is larger,
Forming surface still can be highly suitable, but need to be provided with the elongated slot to connect piston in moulding cylinder side wall, and elongated slot is sealed with steel band, in length
In time use process, steel band can damage and cause powder leakage, to influence the reliable and stable operation of equipment.If retaining second
Kind mode strong point overcomes its deficiency, it is convenient not only to make equipment operation in this way, and substantially increase equipment dependability.
Summary of the invention
The purpose of the present invention is to provide a kind of laser formation machine, which, which may be implemented in, does not increase forming surface and works
In the case of table surface height and device height, increase moulding cylinder piston stroke, to realize increasing processing part size, improves equipment
The purpose of operability and reliability.
Above-mentioned purpose of the invention, which is achieved in that, provides a kind of laser formation machine, it includes rack 1, feeding system
2, powdering hopper and kinematic system 3, blanking Material collecting box for harvesting, molding cylinder barrel and moulding cylinder piston motion drive system, and by laser
The optical system that device, scanning galvanometer, reflection and focus lamp form, the molding cylinder barrel are the scalable cylinder of no less than two sections
Cylinder, lateral expansion cylinder barrel can be placed in lateral expansion cylinder barrel, and every section cylinder barrel center line is overlapped, and piston 84 is installed on innermost
It is connected, can be driven by piston motion drive system in innermost flexible cylinder barrel in flexible cylinder barrel 83 and with the piston bracket 86 that is connected
Inside move up and down.
The telescopic molding cylinder barrel of no less than two sections, has the sealing of sealing element 82, in phase between two adjacent cylinder cylinder
There is cylinder barrel motion guiding device 85 between adjacent two cylinder barrels.
There is sealing element sealing between the piston 84 and innermost flexible cylinder barrel 83.
The piston, which is connected between bracket 86 and the flexible cylinder barrel 83 of most inner side, has cylinder barrel motion guiding device mobile as the two
Guiding.
Laser formation machine of the invention has following beneficial effect:
The laser formation machine thus may be implemented in due to using telescopic moulding cylinder cylinder barrel and not increase work top height
In the case of degree and device height, increase the impulse stroke of molding the cylinder piston, to realize increasing processing part size, improves and set
Standby operability and reliability.
Laser formation machine of the invention is described further with reference to the accompanying drawings and examples.

Specific embodiment
Shown in referring to Fig.1, which is two section telescoping cylinder cartridge forms.The flexible cylinder barrel 81 of outermost and work top and machine
Frame is fixed, and there is the sealing of sealing element 82 in upper end between the flexible cylinder barrel 81 of outermost and the flexible cylinder barrel 83 of most inner side, and there is cylinder barrel shifting in lower end
Action-oriented device 85 is oriented to, and piston is driven to stretch in most inner side by piston motion drive system and be moved up and down in cylinder barrel 83, this
Sample not only ensure that the reliable sealing of moulding cylinder, moreover, under identical work top altitudes, compared with usual single cylinder cylinder,
Piston stroke can be made to lengthen, the larger sized part in working height direction thus may be implemented.
Above-described is only the preferred embodiment of the present invention.It should be pointed out that coming for those of ordinary skill in the art
It says, under the premise of not departing from the principle of the invention and core concept, several modifications and improvements can also be made, be also considered as belonging to this
The protection scope of invention.
