Abstract
The invention discloses a laminated additive manufacturing method of composite materials, comprising the following steps: each thin-film material is pre-compounded through hot rollers to form a multilayer composite material; programmed cutting is carried out with a computer on a product which is required to be manufactured for layering and a cross section contour line of each virtual layer is extracted; the multilayer composite material is cut by a laser cutting system into a physical layer which has a consistent cross-sectional shape with the virtual layer; a lifting workbench declines to the height equal to the thickness of the multilayer composite material; physical layers on the lifting workbench are molten into one piece; and the above steps are repeated until the product which is required to be manufactured is formed. The laminated additive manufacturing method of composite materials requires no die-opening, thus saving die-open time and costs. The scale and lamination order of each thin-film material can be designed according to the need of product performance, and consistence of product performance is good. Different products can be cut from a same multilayer composite material. The method has high degree of automation. In addition, manufactured products are separated from each other, and product density is high.
Description
Technical field
The present invention relates to a kind of material manufacture method, particularly a kind of increasing material forming method of composite of increasing.
Background technology
At present, the application of composite is more and more extensive, and the molding mode of composite has multiple, and the forming method of conventional composite materials mainly contains Wrapping formed, hand pasting forming, pultrusion etc., and these forming method productive labor intensity are large, and cost is high.
The preparation method of tradition laminar composite is: the mould-compacting-temperature programming-demoulding-post processing of die sinking-mould and die preheating-coating releasing agent-cutting lamination composite material cloth-dress, this preparation method need to use vulcanizing equipment preheated mold, automaticity is poor, for the poor thermal conductivity of thicker goods molding compound, some goods part is too large, need the chronic of intensification, production control difficulty is larger; As the composite of mold pressing polyether-ether-ketone, very high to Design of Dies requirement, the too fast meeting that heats up makes to conduct heat inhomogeneous, produces internal stress, causes waste product; Temperature retention time conventionally need to be very long, also needs rear curing processing.On the other hand, in some composite material by adopting tradition pressing process, can produce a large amount of escaping gases, easily make goods produce the defects such as bubble, layering.Need PB repeatedly.In the time manufacturing and designing multiple part, after moulding, between each part, interconnect, need cutting and separating, after products solidifying, cutting can cause product in the time of cutting, to produce defect.
Therefore need to design one and do not need die sinking manufacture, production technology compares uniform and stable simultaneously, can produce the process of stand-alone product.
Summary of the invention
In view of this, the lamination that the object of this invention is to provide a kind of composite increases material manufacture method, with solve existing laminar composite manufacture a product need die sinking manufacture, production process control difficulty large, produce to such an extent that product interconnects defects such as needing cutting and separating.
The lamination of composite of the present invention increases material manufacture method, comprises step:
(1) with winder by each thin-film material rolling compound needs, and make each thin-film material be combined in advance multilayer materials with hot-rolling before winder;
(2) with computer, product to be prepared is carried out to program cutting layering, form each virtual level of composition product, the thickness of each virtual level is the thickness after multilayer materials compacting, and utilizes computer to extract the cross-sectional profiles line of each virtual level;
(3) the cross-sectional profiles line traffic control laser cutting track that laser cutting system extracts according to computer layering cuts out the physical layer consistent with virtual level shape of cross section on the multilayer materials above self-powered platform;
(4) self-powered platform that the has carried physical layer height equating with multilayer materials thickness that declines, after cutting, remaining multilayer materials moves forward, then repeating step (3);
(5) the each physical layer heat on self-powered platform is fused into one;
(6) repeating step (3) is to (5), until form the product of required preparation.
Further, the thin-film material described in step (1) comprises at least one in plastics PE, BOPP, PVA, PA, PVC, PC, TPU, PET, PTFE, PI, PEEK, phenolic resins and epoxy resin.
Further, the thin-film material described in step (1) also comprises at least one in glass fabric, carbon cloth, ceramic cloth, the rare Carbon Materials of Multi-layer graphite, Copper Foil.
Further, in step (5), adopt hot-rolling roll extrusion or laser sintered mode that each physical layer heat is fused into one.
Beneficial effect of the present invention:
1, the lamination of composite of the present invention increases material manufacture method, and its manufacture process does not need die sinking, has saved die sinking time and cost, has avoided that complex parts die sinking difficulty is large, the problem such as percent defective height in production process simultaneously.
2, the lamination of composite of the present invention increases material manufacture method, and designability is strong, can be according to the performance requirement of composite and product, design ratio and the overlay order of each thin-film material, and product each several part consistency of performance is good.
3, the lamination of composite of the present invention increases material manufacture method, and it can cut out different products on same multilayer materials, is conducive on a small scale, many kinds produce continuously, and automaticity is higher.
4, the lamination of composite of the present invention increases material manufacture method, and its product of making is separated from each other, and the product of having avoided existing manufacture method to make interconnects, and needs cutting and separating and cutting and separating properties of product to be had to the problems such as impact.
5, the lamination of composite of the present invention increases material manufacture method, merges because next layer entity layer of every cutting just carries out once heat, therefore can ensure that each physical layer is pressed very fine and closely, and product density is high, minimizing contractibility that can be very large.
