Summary of the invention
At the deficiency that existing quick building mortion exists, the utility model provides a kind of powder materials rapid forming system, and this system can improve the efficient and the quality of quick formation of parts.
A kind of powder materials rapid forming system that the utility model provides comprises processing space and laser scanning device, and wherein, processing space is made of left and right powder discharging device, protective glass, roller or scraper plate, working cavity, working cylinder and working cylinder piston; It is characterized in that: this system comprises two laser scanning devices at least, and the protective glass of equal number, and each laser scanning device is equally spaced, and described working cavity is the vacuum work chamber, keeps hermetic seal with the junction of other parts in the processing space.
The utility model system adopts many laser scanning heads, can improve the efficient of quick formation of parts.A same part is finished the time that the time ratio single sweep device that needs finishes with many scanning means and will be lacked.The utility model system can remedy the deficiency of cost that the logical protective gas of present powder materials rapid forming device brought, part quality, personal safety, environmental protection aspect.Adopt the vacuum forming environment, there is following advantage: first, can isolate extraneous atmosphere to the influence that dusty material is shaped, also can eliminate the influence of dusty material atmosphere that generates in the laser forming process, help the control of component in the powder materials rapid forming process; The second, adopt the vacuum forming environment, help eliminating spheroidizing, increase the wetability of material, improve the interaction of laser and material, thereby help the quick shaping of dusty material; The 3rd, help increasing the flowability of dusty material, help the dehydration and the degassing in the Reciprocity of Laser ﹠ Materials process.
In sum, the utility model system is fit to make fast metal parts, ceramic part, macromolecule part and composite material parts.
Description of drawings
Fig. 1 is the structural representation of the utility model system;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the schematic layout pattern of multi-laser probe device.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example.
As shown in Figure 1, the utility model system is made of processing space and the laser scanning device more than two or two.Wherein, processing space 7 is made of left and right powder discharging device 1,4, protective glass group 8, roller (or scraper plate) 14, working cavity 9, working cylinder 11 and working cylinder piston 12.
Laser scanning device is made of probe and the laser generator that is attached thereto.As shown in Figure 2, probe 2,3,5,6 is equally spaced in the top of working cylinder 11.Probe is realized focusing on, and laser scanning device realizes that the selective laser of dusty material is shaped fast.
For making their compact conformation, the installation dimension of probe and scan field dimension are arranged by the equidistant mode in subarea-scanning field.As illustrate shown in Figure 3ly, and scanning field 15 is a square, and it is divided into subregion A, B, C, D such as four, and scanning is finished by the probe 2,3,5,6 of correspondence respectively in each zone.Protective glass group 8 is made up of four protective glasses, they be positioned at probe 2,3,5,6 the laser beam eye point under, the equidistant installation realized subarea-scanning.Scanned by the wait subregion A of the protective glass below it to its correspondence by laser scanning head 2 emitted laser bundles, in like manner, laser scanning head 3,5,6 is responsible for subregion B, C, D such as scannings.The single laser scanning device of the many scanning means of many laser scans under computer control, and its two or more laser scanning devices can be realized synchronous scanning under computer control.When being shaped a part, each laser scanning device in the multi-laser scanner scans the different piece of the CAD 3D entity slicing layer of part simultaneously under computer control.When being shaped a plurality of part, each laser scanning device in the multi-laser scanner can scan the slicing layer of different parts respectively under computer control.
Dusty material is equipped with in left and right powder discharging device 1 and 4 inside, and its meal outlet communicates with working cavity 9.Roller 14 is positioned at working cavity 9 the insides, spreads powder by common electric machine control roller 14 along continuous straight runs of Frequency Converter Control as bidirectional-movement.From left powder discharging device 1 to right powder discharging device 4 or right powder discharging device 4 once spread powder one deck to left powder discharging device 1 every motion; Laser scanning device is provided with protective glass group 8 at the top of working cavity 9 between left and right powder discharging device 10 and 11.The number of protective glasses is identical with the number of laser scanning head in the laser scanning device in the protective glass group 8, and lay respectively at correspondence laser scanning head under.
Be provided with working cylinder 11 in the bottom of working cavity 9, be provided with working cylinder piston 12 in its working cylinder 11, working cylinder piston 12 is vertically moved up and down by independent step motor control.Working cavity 9 external vavuum pumps, the junction of other parts in working cavity 9 and the processing space keeps hermetic seal, forms the vacuum work chamber.The laser beam that laser scanning device sends acts on the powder to be processed of working cylinder piston 12 upper surfaces by protective glass group 8.Whenever process one deck, the distance of working cylinder piston 12 declines one layer thickness, among the figure, the part workpiece that 10 expressions have been processed; The unnecessary dusty material of 13 expressions.
Multi-laser in this kind device can be any one in carbon dioxide laser, YAG laser instrument, optical fiber laser, the ultraviolet laser.As the quick shaping carbon dioxide laser of macromolecule, pottery, sand dusty material, quick shaping the YAG laser instrument or the optical fiber laser of metal powder material.
The utility model system is two key components with the difference of existing powder materials rapid forming device; it is many probes of multi-laser device that the first changes present single laser single sweep device, and it two is that the working cavity that changes at present logical protective gas environment is the vacuum environment working cavity.
