Description
Technical field
The present invention relates to increases material manufacturing technology field, substrate is reused in specifically a kind of increasing material manufacturing.
Background technique
Increases material manufacturing technology (also referred to as " 3D printing ") is based on Computerized three-dimensional CAD model, by the way of successively accumulating
Directly manufacture the method for three dimensional physical entity.In view of the superiority of increasing material manufacturing itself, occur all kinds of specific aim 3D at present
Printing technique is such as: precinct laser fusion, direct metal fusion sediment, the solidification of photosensitive resin selectivity, precinct laser sintering, 3D spray
Penetrating modes, the these types of 3D printing methods such as printing has the bottom plate depended on using substrate as 3D printing workpiece.Thus substrate table
The Pingdu in face and the depth of parallelism of substrate top and bottom directly affect 3D printing workpiece quality.
Below for industrially using relatively broad precinct laser fusion 3D printing technique at present, to illustrate substrate
Influence of the geometric tolerance to printing workpiece.
Precinct laser fusion process is will to be laid in substrate surface by metal powder material from level to level using scraper.It is logical
Control system control laser beam is crossed, the profile on powder according to workpiece in the section of this layer is scanned.Make the temperature of powder
Melting point is risen to, clinkering forms the initial section of workpiece.3D printing workbench declines the thickness of a powdering layer together with substrate therewith,
Powder is tiled to the upper surface of molded workpiece interface again by scraper, and is heated to being just below the powder clinkering point
A certain temperature controls laser beam by control system, then is scanned on powder according to the cross section profile of this layer, makes powder
Temperature rises to melting point and carries out clinkering again, and realizes and bond with following molded part.After the completion of this layer cross section clinkering,
3D printing workbench will decline the thickness of a powdering layer together with substrate again, and dusty material carries out again by scraper above flat
Paving carries out the clinkering of a new layer cross section, until completing entire workpiece.Entire 3D printing work is risen after workpiece printing finishes
Platform cleans up excessive powder and removes workpiece of the clinkering on substrate from 3D printing workbench together, cut by line or its
He separates workpiece and substrate process means.Most start substrate and 3D printing work when printing it can be seen from the above-mentioned course of work
The flat conditions for making the surface of platform are directly related to scraper in the packed uniform situation of the powdering layer of substrate surface.And 3D printing work
Make the smooth of platform to be determined by equipment, equipment manufacturer can disposably mix up during installation, but substrate is then different, and substrate is can be into
The row later period is machined or by workpiece printing person's self manufacture, is installed on 3D printing workbench by screw.Therefore substrate
By the flatness in powdering face, the depth of parallelism on substrate two sides by powdering surface and between 3D printing workbench binding face is to powdering layer
Packed uniform situation influence it is the most direct.And due to during increasing material manufacturing by preheating and laser sintered process high temperature
It influences, substrate surface can generate certain deformation quantity after the completion of printing every time, and cut the workpiece meeting of separation after printing from plate line
Workpiece pedestal or support are remained by powdering face in substrate, in order to achieve the purpose that the recycling of substrate can all carry out substrate again
Secondary milling is processed come the depth of parallelism of the flatness and upper and lower surface that guarantee the surface of substrate.
The prior art as shown in Figure 1, after the completion of the increasing material manufacturing, by mill, grind substrate by powdering face, make the flat of its face
Face degree reaches requirement；Then substrate is regard as datum level by the overturning of powdering face, milled, the binding face of mill and 3D printing workbench,
The flatness in face required for reaching and the depth of parallelism on two sides.It is bonded due to substrate by powdering face and with 3D printing workbench
The area on face two sides is larger (as shown in Figure 1), causes milling that man-hour requirement is added to use biggish milling cutter or grinding wheel, causes in this way
Coolant liquid is difficult at the point of a knife for being ejected into milling cutter completely when processing or grinding wheel and workpiece cut contact position, when causing cutting it is cooling not
Enough heat waste cutters reduce processing efficiency；The abrasion of milling cutter or grinding wheel cutter during the cutting process, also causes the phase of round-trip milling
The height in adjacent two positions face will be different；Working (finishing) area is larger to be also led to milling cutter or grinding wheel and cuts number back and forth and increase, and is made
Obtain the deformation of workpiece machined surface accumulation of heat；Working (finishing) area is larger to cause round-trip milling direction to be not easy to adjust consistency, will lead to
Adjacent position removes quantity of material and generates difference.
Thus existing substrate processing method, it is more difficult to the depth of parallelism for reaching required facial plane degree and two sides, especially with difficulty
Guarantee the depth of parallelism outstanding problem on substrate two sides.And the flatness of real estate and the depth of parallelism on two sides, directly influence each 3D
The uniform closely knit situation of powdering when printing.And the difficulty of processing of existing substrate, cause each process time too long and it is economical at
This is higher, reduces the service efficiency of substrate.
Secondly, substrate after the completion of 3D printing, is directly freely placed in above line ceding of Taiwan frame by the prior art manually, carry out
Line cuts the separation with substrate.Since substrate is freely to be placed in above line ceding of Taiwan frame manually, it is difficult to guarantee substrate and line ceding of Taiwan frame
Verticality and the depth of parallelism, therefore line cuts separation workpiece and substrate every time, can artificially be left remaining work on powdering face in substrate
Part pedestal and support, and lead to secondary grinding Milling Machining of the substrate to be carried out by powdering face.In this way make substrate to reusing
Time is too long, also reduces working efficiency, and then increase processing cost.
Existing substrate thickness is that 15mm (as shown in Figure 1) thickness is excessively thin, repeatedly repeatedly under the external forces such as sandblasting or
Moderate finite deformation amount is also easy to produce in the heated situation of laser.
Summary of the invention
The present invention is to overcome the shortcomings of in the above-mentioned prior art and provide a kind of increasing material manufacturing and reuse substrate, including phase
Mutually parallel substrate is by powdering face and workbench binding face, it is characterised in that the workbench binding face setting at least three is convex
Platform, on the substrate on be provided with counter sink, the counter sink is used for the fixed installation of substrate and 3D printing workbench.
Further, the counter sink is located on boss.
Preferably, there are four the boss, four right angles of the workbench binding face are separately positioned on.
Further, the thickness of the substrate increases by 50%~100% relative to conventional substrate.
Preferably, the thickness of the substrate increases by 60%~80% relative to conventional substrate.
Preferably, the thickness of conventional base plate is generally 10-20mm, and substrate thickness of the invention (including boss) is 15-
40mm, it is further preferred that being 16-36mm.
The repeated using method of substrate is reused based on a kind of increasing material manufacturing, it is characterised in that the following steps are included:
Step 1, after the completion of increasing material manufacturing, obtained by cutting separating base plate and workpiece by powdering face, make the flat of its face
Face degree reaches requirement；
Step 2 regard substrate as datum level by the overturning of powdering face, what planarizing process and 3D printing workbench fitted

Step 3, the 3D printing table surface that the surface of boss after processing is completed is fitted in 3D printing equipment, with tight
Substrate is anchored on 3D printing workbench by firmware；
Step 4, material powder are tiled in substrate by powdering face, to realize that powdering is uniformly closely knit when 3D printing, more preferably
Guarantee 3D printing workpiece quality.
Further, the cutting mode in step 1 is chosen as the conventional cutting mode such as laser cutting, wire cutting.
Further, it is preferable to be cut to cut tooling line using fixed substrate line.
Specifically, fixed substrate line described in step 1 cuts tooling, including be bonded with substrate substrate fitting stationary plane,
Fixed mechanism, the fixed mechanism are bonded for substrate fitting stationary plane with the surface of substrate boss.
Specifically, the fixed mechanism includes fixed screw holes, fixed spoke, clamping screw, passes through the clamping screw
Fixed spoke and line ceding of Taiwan frame is set to be linked to be entirety.
Further, the mode of planarizing process described in the step 2 is chosen as milling and/or grind.
Specifically, step 1 middle line, which cuts separating base plate, and workpiece is obtained reaches the flatness in its face by powdering face to want
It asks method particularly includes: substrate boss face is fixed on substrate fitting stationary plane, alignment plane side is corrected by using dial gauge
Method controls so that the flatness and verticality of substrate and line ceding of Taiwan frame are within 0.05 millimeter of the margin of tolerance, so that line be made to cut
Cutting wire adhesive substrates by powdering face directly cut separation workpiece and substrate, obtained substrate be in by the flatness allowance of powdering
Within 0.05 millimeter.
Since the boss (such as Fig. 4) that substrate manufacture of the present invention comes out certain altitude uses substrate binding face relative to existing
(such as Fig. 1), area greatly reduces, and boss integral face of the present invention is caused to be more easily implemented the flatness in face.Because of boss of the present invention
(such as Fig. 4) integral face causes to process relative to the reduction of existing substrate binding face (such as Fig. 1) and the reduction of overall processing area
When can be using smaller milling cutter or grinding wheel, coolant liquid can be easier to be ejected into milling cutter point of a knife or grinding wheel and work compared with prior art
Part cuts contact position, so that greatly reducing when cutting to the loss of cutter, improves processing efficiency.Milling cutter or grinding wheel are in cutting process
The reduction of middle tool wear is also beneficial to the consistency of the height in the adjacent two positions face of round-trip milling.Process entire area
Reduce, the number for being also advantageous for milling cutter or the round-trip milling of grinding wheel is reduced, and can effectively reduce the deformation of workpiece machined surface accumulation of heat.
Overall processing area reduces, and is also easier to adjust round-trip milling direction, guarantees that workpiece surface goes the consistency in material direction, make past
It returns adjacent position removal quantity of material and keeps identical.
So boss (such as Fig. 4) of the present invention is more easily implemented the flatness on surface.
Fixed substrate line of the present invention cuts tooling (as shown in Figure 6), is fixed by the way that substrate boss face is fixed on substrate fitting
The form in face enables the flatness and verticality of substrate and line ceding of Taiwan frame to control within the margin of tolerance by playing table.To
It pastes wire cutting silk and is directly cut separation workpiece and substrate by powdering face with substrate, obtained substrate is by the plane of powdering
Tolerance is within claimed range.The more existing mode cut without using the direct line of tooling of such mode, more can directly guarantee that line is cut
The precise degrees of plane.And cut tooling using fixed substrate line of the present invention, the substrate that line is cut out by powdering face, will not be artificial it is residual
Workpiece pedestal and support are stayed, so that substrate directly reaches the standard of reusing by powdering face.Therefore it has been subtracted pair compared with the prior art
By powdering facing cut, grinder part remnants pedestal and support link, the time that substrate reuses is shortened, improves work effect
Also reduce processing and fabricating cost while rate.
Completion of processing is cut when substrate of the present invention cuts tooling (such as Fig. 6) mode line by invention fixed substrate line by powdering face
Afterwards, four small areas on the surface of processing boss are gone again as benchmark face by powdering face using substrate.Boss is easily achieved due to aforementioned
(such as Fig. 4) flatness reason, and substrate is more easily implemented by the depth of parallelism between powdering face and boss face, and mill, mill amount
Very small process time is also very short.
So substrate is by the depth of parallelism between powdering face and boss face, it is as shown in Figure 1 relative to existing used substrate
Substrate is more easily implemented by the depth of parallelism in powdering face and substrate binding face two sides.
