This invention realizes precise bendingcontrol, reduce cost, and increases efficiency.
Description
(1) technical field
The present invention relates to a kind of production method of three-dimensional objects of suitable for foldable forming.
(2) background technology
Since the eighties in 20th century, the extensive use in manufacturing industry along with computer-aided design and Computer-aided Machine processing, product has all had very great development from shape-designing to making, industrial products more and more develop to small lot, high accuracy and complex geometric shapes direction, and construction cycle, production cycle are shorter and shorter.Manufacturing industry is faced with the problem of " how doing sooner ".Traditional manufacture method more and more can not satisfy the needs of " how doing sooner ".And the method for tradition manufacturing three-dimensional objects (as metallic shield) has: 1) die stamping moulding process, its defective mainly are the die cost of great number and hand over the phase slowly that mould is not easy to change etc.; 2) the mechanical-moulded technology of photochemical etching, it than die stamping moulding further by combining of photochemical etching moulding process and die stamping moulding, shortens its friendship phase, and cost reduces.
The photochemical etching forming technique is based on the modern integrated manufacturing technology that grows up on the basis of technology such as microelectric technique, computer technology, new material technology and fine chemistry industry, develops rapidly at home after 95 years.But this technology development situation also only is confined to the planar metal thin-wall part so far, for example: aperture plate, various circuit lead frame, grating and fluorescent display screen display etc.To select this method for use for the metallic shield that need are three-dimensionally shaped, then only by other subsequent technique, just can finish finished product such as punch forming, mould molding etc., or simply select for use rapidform machine etc. just to be achieved, this has just increased cost far away, has prolonged the production time etc., cause this technology can only be confined in the product on plane, it is then powerless to face three-dimensional product.
(3) summary of the invention
Technical problem to be solved by this invention is to provide a kind of technology simple, can be used in the production method of the three-dimensional objects of suitable for foldable forming.
The production method of the three-dimensional objects of described suitable for foldable forming comprises:
(1) mask manufacture:
1. Computer simulation design is carried out design of Simulation and folding test emulation repeatedly according to product drawing or prototype to product, draws the data that etch partially parameter, method for designing of each bending part;
2. mask design, output are carried out integrated design to product, according to simulation result and design and etch partially, carry out mask output;
3. mask contraposition, correction are proofreaied and correct and contraposition mask;
(2) optical etching
1. with raw material metal after surface treatment, two sides roller coating photoresist, the oven dry;
2. mask and roller coating is good two-sided alignment of raw material, photoetching is developed then;
3. the good raw material that will develop are put into etching machine and are carried out etching, the demoulding then;
(3) manual bending and molding
The product that the demoulding is good is turned up by expert worker along etching partially line, obtains three-dimensional objects at last.
Production method of the present invention is specially adapted to produce metallic shield.Further, described three-dimensional objects is a metallic shield.
Further, described mask design adopts AutoCAD software that product is designed.
Because the raw material metal surface has impurity such as grease, dust, rust staining, thereby often need carry out surface treatments such as oil removing, rust cleaning to the raw material surface.A kind of degreaser component ratio of recommending is as follows:
NaOH (NaOH): 20～50g/L
Sodium carbonate (Na2CO3): 20～60g/L
JC2006 additive: 5～10g/L
Treatment temperature is recommended in 70～90 ℃, till the processing time eliminates down to oil.Above-mentioned JC2006 additive is a kind of neutral surface active agent, and its main component is a peregal.
The photoresist of raw material metal surface roller coating is 20～40 microns with thickness and is advisable the required thickness uniformity.Oven dry can be adopted following technology: the raw material metal of the good photoresist of roller coating is put into baking oven, and 70 ℃ of bake out temperatures, 15～30 minutes time, dry, take out cooling.
The two-sided alignment of raw material that above-mentioned photoetching is normally good with mask and roller coating put into exposure machine and exposed, and the time was generally 15～30 seconds.
Above-mentioned described development is generally carried out in developing machine, and solution ratio can adopt as follows: Na
2CO
3: 2～5g/L, BaCL
2: 0.2～0.5g/L, temperature is at 25～45 ℃, the time: 5～6 minutes.Usually the semi-finished product that developed are checked defective item must not flow into next process.
Above-mentioned etching solution for etching can adopt liquor ferri trichloridi, and its proportioning is as follows: water: 1000g/L, and ferric trichloride: 28～40g/L, temperature is 50～70 ℃.
Above-mentioned demoulding can adopt the alkali lye of following proportioning: NaOH 25g/L, 70～80 ℃ of temperature.
The three-dimensional objects that finally obtains generally detects again, packs at last to get final product.
Production method of the present invention has utilized the method for etching partially in the photochemical etching to locate bending start position and angle, realizes the accurate bending of product is controlled by double etched design.It is simple that this method is used to make three-dimensional objects (as metallic shield etc.), and cost is low, the efficient height.
