Abstract
The present invention belongs to the field of quick prototype technology, including the following steps: firstly, laying a layer of sheet material, then said layer is predivided into several small portion by cutting under the control of computer; adhesion bonding or connecting processes are adopted to make newly-laid layer sheet material firmly-fix on the formed body, cutting out profile of said layer by cutting under the control of computer, cutting off non-part portion; laying a layer of new sheet material again, repeating said operation until said working process is completed, finally removing lattice portion so as to obtain complete prototype part. Said invention can make prototype deformation small, and make the produced part process high accuracy and strength, can be used in field of large-size die manufacture technology.
Description
The invention belongs to rapid prototyping technology field, the improvement of the rapid prototyping technology that particularly continuous synusia is piled up.
The rapid prototyping technology (Rapid Prototyping Technology) that continuous in the world at present synusia is piled up is all being followed and is being unified principle, promptly, obtaining synusia is bonded to 3D solid according to the continuous layering geological information cutting foil (as paper, potsherd, sheet metal etc.) of part.Specific embodiment as shown in Figure 1, at first the layer overlay foil uses cutter (as laser, icking tool etc.) to cut out this layer profile then under computer control, non-part part all is chopped into fritter so that excision.After this layer is finished, repave the last layer foil, with method (as the heating pressurization) bonding or that connect, make firm being fixed on the molded body of one deck of newly spreading, cut the profile of this layer again, so repeatedly up to completion of processing.Remove the chopping part at last to obtain complete prototype parts.
In above-mentioned layering manufacture process,, just formed residual stress in inside when new layer 21 is deposited in when existing on the old layer 22.The generation of this residual stress is because new layer 21 all will be through the contraction process of supersolidification and cooling or the process that applies through periodically big pressure.So residual stress in the already present layer 22 and because the contraction of new layer 21 has just caused the bending between two-layer, as shown in Figure 2.But when type length during less than 400mm, this problem can manifest substantially, and increases when type is long, especially after type length surpasses 800mm, because the size of part is big more, the bond area of interlayer is just big more, and the Deformation control of the reliable bonding and prototype of sheet layer material is just difficult more.It is outstanding especially that distortion shown in above-mentioned just seems, it has not only influenced part precision intensity, and can have a strong impact on normally carrying out of manufacture process, causes making satisfactory prototype parts.
The objective of the invention is for overcoming the weak point of prior art, a kind of pre-segmentation fast prototype making process is proposed, on the basis of original technology, added the technical process of a pre-segmentation, make sheet layer material bonding reliable, the distortion of prototype is little, part precision height, the intensity of producing are big, RP technique can be applied in large mold and make the field, have vast potential for future development.
A kind of pre-segmentation fast prototype making process that the present invention proposes may further comprise the steps:
(1) first layer overlay plies of material;
(2) use cutter then under computer control, this layer is carried out pre-segmentation according to some grid configurations that configure;
(3) with method bonding or that connect make one deck of newly spreading through after the pre-segmentation firm be fixed on molded body
On;
(4) under computer control, cut out this layer profile with cutter then, non-part part all be cut into the grid fritter with
Be convenient to excision;
(5) after this layer is finished, the new plies of material of layer overlay again, (1)-(4) are so repeatedly up to completion of processing;
(6) remove redundance at last to obtain complete prototype parts;
Moulding material of the present invention can be foil such as paper, potsherd, plastic sheeting, sheet metal etc.Bonding way can adopt multiple modes such as pre-coated bonding agent, real-time adhesive-applying, mechanical connection.
Advantage of the present invention is: in new plies of material bonding with existing material layer or be connected before, new plies of material is pre-segmented into a plurality of fractions earlier with cutter.Since big moulding material by indirect be divided into some little parts (＜400mm), so just can control the distortion of part preferably, phenomenons such as bending crack appear no longer.
