Brief description of drawings
Referring now to accompanying drawing, only with the way of example embodiment of the present invention will be described in more detail, wherein:
Fig. 1 is the side view of accelerated model manufacturing equipment;
Fig. 2 is the plan view of Fig. 1 equipment, and
Fig. 3 is the side view of Fig. 1 and 2 equipment.
Preferred forms
With reference to accompanying drawing, accelerated model manufacturing equipment of the present invention represents with 10, and comprises a support platform 11, and its is provided with on the support rails 12 of parallel installation in vertical direction, platform has accurate rising and reduces mechanism, for example adopts electrically operated ball-screw (not shown).In Fig. 1 lower position, represented support platform with the chain-dotted line profile.
A planer-type superstructure 13 accurately is positioned at above the support platform 11, and has the horizontal guide rail 14 of the vertical X-axis that is supporting first slide 15, and slide itself has the horizontal guide rail 16 of the horizontal Y-axis that is supporting second slide 17.Therefore, in the superstructure zone, second slide 17 can move on to any position of being determined by X and Y coordinates on support platform 11 and loose structure sheet material 23.
A pair of cylinder 20 and 21 is located at the two ends of support platform 11.The conventional drive unit of cylinder 20,21 usefulness connects, and is respectively feed and haulage drum, is used for the loose structure sheet material is delivered to platform 11 continuously.Sheet material 23 is tensioned to predetermined value, be enough on support platform to keep tightening and not having waveform, but deficiency so that sheet material tear or extend.Required tensile force value will be determined according to the sheet material characteristic, and be realized by spring-loaded regulating wheel.
In this example, sheet material is low-density expanded polystyrene material, thickness 3mm.
Low-density expanded polystyrene material is inhomogeneous and inflammable, makes the cutting accuracy of laser instrument be restricted.But, for the use of contemplated finished product model, the disposable model of using during metal casting for example, required precision is not high.
Used adhesive is a hot melt adhesive, therefore must be provided with heater on glue spraying head 19.
Except sliding assembly 15,17, a floating device such as roller also have been installed, or illustrated brush or squeegee 25, it can move on horizontal guide rail 14 along X-direction, as representing with chain-dotted line among Fig. 1.
It is as follows as the equipment operation of the model of casting usefulness to make a model or object:
Then in the program of user input, for example under the control of a cover CAD program, first slide 15 that is contained on the portal frame and the sliding assembly of second slide 17 are moved.Operate lasers 18 under suitable power, and make it penetrate sheet material 23, fitly cut to the entire depth of sheet material, therefore intactly cut out one or several part from sheet material 23, and they are stayed on the platform 11.Close laser instrument 18 then, sliding assembly moves along cutting out part by projected route again, and this moment, glue spraying head 19 was started working.The part that cuts out is coated with or partly is coated with gluing.Glue can be limited in laser instrument and cut out near the scope in limit, also can cover whole surface, perhaps does right-angled intersection from the teeth outwards.If desired, can be followed by the laser beam gluing when cutting operation.
Utilize guide rail 12 to reduce support platform 11 gradually, reduce the thickness that surpasses a foam sheet 23. Operate cylinder 20 and 21 again, the useless sheet material that cut is moved on on the haulage drum 21, and other sheet material sent to from feed cylinder 20 cover support platform.The support platform 11 that raises gradually makes that the sheet material of gluing has cut out part to contact now and below the other sheet material.
Floating device 25 was smeared the upper surface of other sheet material 23, and other sheet material 23 is adhered on the glue that foam sheet on the support platform 11 cuts out part securely.
Operation and mobile laser instrument 18 cut other sheet material again.Importantly, the entire depth of control cutting carefully preventing from further to cut to the lower part that is cut out by laser instrument in the operation formerly, and guarantees to cut other sheet material.It should be understood that under the control of CAD program every synusia material can cut out different shapes.
Other adhesive spraying from the part that other sheet material cuts out, is reduced support platform once more, send sheet material to, raised platform, floating sheet material and the cutting of carrying out again are till finishing desirable model.Cut out not gluing of the top partly at last, support platform is reduced at utmost, to remove model.
When equipment begins to operate, and consider the lightweight character of loose structure foamed material, can take measures to make the part that cuts out first to locate, prevent that it is mobile on support platform 11, otherwise it may be to the adverse effect that is formed with of finished product model.Therefore umbo as spike can be set on platform 11, and it highly is substantially equal to the thickness of sheet material, arrives 5mm as 3mm.But indentation spike during beginning, avoiding tearing the sheet material of sending to first on platform, but after this spike remains on the operating position of rising.Or, can fully reduce platform, make that be fixed on spike on the platform is positioned at and avoids this under the original feed sheet material of tensioning and tear, raised platform makes its position facing to below the sheet material then.
It should be understood that can revise above-mentioned equipment and method with the way of example explanation is used for other porous sheet.For example, thicker porous sheet may be harder, thereby can adopt the sheet material feeder of any routine, is the vacuum type feeder as air suction type, and perhaps gravity bin stock feeder type is sent in discontinuous sheet material mode rather than in the mode of continuous coiled material.For other material, the laser instrument cutting can be cut by jet, plasma cuts or the heater strip cutting substitutes.In other words, higher thereby the heavier laser instrument of power if desired, may need to adopt fixed laser to substitute direct vertically arranged laser instrument by " flight optical " operation, that is to say, the chopped beam of laser instrument is provided by removable speculum and/or lens are formed on superstructure a system.
