Description
One, affiliated technical field
The invention belongs to the advanced manufacturing technology field, relate to Rapid tooling, the mould manufacturing method that particularly a kind of metal spraying and brush plating combine based on rapid prototyping technology.
Two, background technology
Rapid die-manufacturing (Rapid tooling-RT) is exactly the technology of die manufacturing that utilizes rapid shaping technique (rapidprototyping-RP) production mould prototype or master mold.Present RT technology mainly concentrates on two big research directions: one is direct rapid die-manufacturing (direct rapidtooling--DRT), and one is indirect rapid die-manufacturing (indirect Rapid tooling--IRT).
Directly Rapid tooling does not rely on the traditional moulds manufacturing process, is subjected to extensive attention.Relatively typical method has: sintering method of impregnation, sheet metal layered manner, the long-pending method of Metal Melting etc.Be subjected to the restriction of moulding material and technology, directly the molding method also is in the laboratory research stage substantially, can only be used for making the less test mould of some volumes.
Rapid tooling has two kinds of die-manufacturing methods indirectly: first kind is that the prototype made from the RP method is model (plastics, a wax etc.), combine with the traditional moulds manufacturing process, produce mould by this model with methods such as casting method, electrode moulding, metal sprayings, second kind is to produce casting mold (sand mold or shell mould) by the RP technology, again by foundry engieering with these sand molds or shell mould production mould.Indirect rapid die-manufacturing method is relatively more flexible, applied range, can make the mould of multiple material, is the main path that realizes RT at present.Be divided into three major types by mold materials, i.e. nonmetal mould, semimetal mould and metal die.
1) nonmetal mould mainly contains: silicon rubber mould, epoxy resin mould, this class mould can be obtained by the RP prototype system of directly turning over.
2) metal die generally obtains in conjunction with processes such as sintering infiltration, casting, electric machining by the RP prototype.
3) the semimetal mould generally forms metal thin shell by electroforming or door metal spray-coating method, carries out the process acquisition of reinforcement then with nonmetallic materials or composite.The metal spraying mould making process is to adopt plasma spraying or arc spray process spray metal thin shell on RP prototype or RP prototype are turned over the stage die of system, carries out reinforcement with resin, metallic composite then, obtains injection mould or sheet-metal press working mould.
Nonmetal mould low cost of manufacture, cycle based on the RP technology are short, and being used for new product development under some specified conditions has good effect, but because the restriction of the mechanical property of materials, it is of limited application.Based on the general more complicated of manufacturing process of the metal die of RP technology, cost is also high, also is difficult to the manufacturing of large mold at present.By contrast, applied widely, characteristics such as cost is low, suitable manufacturing large mold that the semimetal mould has have the good engineering practical value.
Metal spraying by electric arc is compared with other plasma spray technologies such as plasma spray, flame-sprayings, have that equipment investment is few, technology is simple, production efficiency is high, energy savings, to advantage such as the matrix thermal output is little, applied widely, in recent years, in the mould manufacturing, be subjected to extensive attention.The method of metal spraying by electric arc molding is manufactured on the cycle for big-and-middle-sized mould and the cost aspect has very big advantage.Refractory metal is because the cooling shrinkage factor is easy to cracking greatly, curling is difficult in the moulding of prototype surface attachment, effective, the technical maturities of low-melting-point metal spraying molding such as the pseudo-alloy of Zn or Zn-Al, but coating hardness is too low, has had a strong impact on the scope of application of spraying mould.
The brush coating technology is an Applied Electrochemistry deposition principle, at the surface strengthening technology of the selected position of the surface of the work that can conduct electricity fast deposition appointed thickness coating.By surface preparation one deck brush coating, can greatly improve performances such as the hardness, intensity of component surface, wear-resisting, anti-corrosion and resistance to high temperature oxidation at parts.
Electric arc spraying deposition efficiency height, but coating hardness is low; The brush plating can obtain the coating of high strength and high rigidity, but deposition velocity is low.
