Abstract

The utility model relates to a molding operation platform of a selectivity laser sintering device. The molding operation platform comprises a base and an aluminum plate which is paved on the base. Through holes or groove holes are evenly distributed in the aluminum plate, organic glass is injected into the through holes or the groove holes, and the aluminum plate is fixed on the base through screws. The molding operation platform of the selectivity laser sintering device is simple in structure and low in cost. The rigidity, the flatness and the operating temperature uniformity of the operation platform are improved, and the occurrence that the molding quality of a product is affected because of the deformation of the operation platform caused by thermal expansion and cold contraction is prevented.

Description

A kind of shaping work platform of selective laser sintering equipment
Technical field
The utility model relates to a kind of workbench, is specifically related to a kind of shaping work platform of selective laser sintering equipment.
Background technology
Selective laser sintering (being called for short SLS) technology is to utilize the principle of dusty material sintering under the laser irradiation, is piled into type under computer control layer by layer.The SLS process is to adopt powder-laying roller that one deck dusty material is tiled in the upper surface of molded parts, and the control laser beam scans at bisque according to the cross section profile of this layer, makes powder sintered and realizes bonding with following in type part.After a layer cross section sintering was intact, the descend thickness of a layer of workbench, stone roller is layer overlay powder uniformly densely in the above again, carried out the sintering of a new layer cross section, until finishing whole model.Thereby the locating effect of model has directly influenced Forming Quality in forming process.Yet the model of prior art is not fixed model in sintering process, and in addition, expanding with heat and contract with cold of workbench makes model generation displacement also can influence the SLS Forming Quality.Therefore, the shortcoming that exists in the prior art is necessary prior art is made improvements.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, provide a kind of simple in structure, cost is low, the shaping work platform of the selective laser sintering equipment of good forming effect.
The utility model is to realize by following technical scheme: a kind of shaping work platform of selective laser sintering equipment, described shaping work platform comprises a base and is layed in aluminium sheet on the base, evenly be laid with through hole or slotted eye on the described aluminium sheet, be perfused with lucite in described through hole or the slotted eye, described aluminium sheet is fixed on the base by screw.
Described aluminium sheet is that bottom side length is 280mm, and height is the cuboid of 15~20mm.
The aperture of described through hole is 5mm.
With respect to prior art, the utility model is by evenly being laid with through hole or slotted eye on aluminium sheet, dusty material can be covered with on through hole or slotted eye, when the ground floor of model sintering, lucite fusion in ground floor dusty material and through hole or the slotted eye, after the laser pulse, the lucite in ground floor dusty material and through hole or the slotted eye cools off simultaneously and is consolidated, and can not be shifted when making the model sintering.Because model and workbench metal covering have suitable contact area, metal is conducive to the rapid transmission of heat and is evenly distributed, thereby model internal stress anisotropy is reduced, and has increased intensity, and dusty material is in conjunction with tightr, and model is not easy cracking or distortion.This shaping work platform just needs to change in distortion or after having grown the difficult material dirt piece of removing, and cost is low, fabrication and installation are easy, long service life.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the shaping work platform of the utility model selective laser sintering equipment
The accompanying drawing identifier declaration:
1, base
2, aluminium sheet
3, through hole
4, screw
The specific embodiment
The shaping work platform of of the present utility model a kind of selective laser sintering equipment as shown in Figure 1, this shaping work platform comprises a base 1 and is layed in aluminium sheet 2 on the base 1, evenly be laid with through hole 3 or slotted eye on this aluminium sheet 2, be perfused with lucite in this through hole 3 or the slotted eye, this aluminium sheet 2 is fixed on the base 1 by screw 4.
Aluminium sheet 2 is 280mm for bottom side length, and height is the cuboid of 15~20mm.The aperture of through hole 3 is 5mm.Also can be perfused with lucite in this through hole 3 or the slotted eye, certainly also can pour into other and can realize organic material with dusty material fusion and difficult carbonization.The chemical name of lucite is polymethyl methacrylate, and the English PMMA that is called for short is formed by methyl methacrylate polymerization.
During the work of selective laser sintering equipment, model need be realized dish and disk stripping at workbench:
Last dish:
1, in Three-dimensional Design Software, adds complementary model base to three-dimensional model.The general height of model base is 2~3mm.
2, bed thickness height of shaped platform decline, the closely knit uniform dusty material of powder-laying roller layer overlay, this dusty material also is covered with on through hole 3 or slotted eye simultaneously.
3, laser pulse scans at dusty material, not only makes the dusty material fusion, and makes the lucite fusion in through hole or the slotted eye.After the laser pulse, the lucite in dusty material and through hole 3 or the slotted eye cools off simultaneously and is consolidated.The workbench bed thickness height that descends again, powder-laying roller is the closely knit uniform dusty material of layer overlay again.After the laser scanning multilayer, the model base of generation just is bonded together with aluminium sheet 2 securely, even and then be subjected to a bit rubbing unexpectedly in whole forming process also can not moving.
Disk stripping:
1, behind the intact last one deck powder material of laser scanning sintering, waits for 5~10 minutes.
2, make workbench rise to initial position.
3, the powder material around the cleaning model.
4, further clear up powder material on the model with vacuum cleaner, model and workbench are appeared.
5, make the perching knife edge of a knife facing to model finished product bottom, blade is pasting the workbench surface, and little hammer raps hilt continuously, and the edge of a knife is inserted between model finished product and the workbench gradually, until the two separation.Or directly the model finished product is upwards extracted, the bottom excess stock is removed in reprocessing.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
