Description
Technical field
The present invention relates to the manufacturing equipment of the fast mould shell in the advanced manufacturing field, particularly a kind of high-melting metal arc spraying intelligent manufacturing system.
Background technology
The metal arc spraying rapid die-manufacturing technology is a kind of mold making technology based on " duplicating "; It with a mock-up (or being called prototype) as master mold; With electric arc is thermal source,, and makes its injection, is deposited on the master mold surface the atomizing of the metallic substance of molten state through high velocity air; Form certain thickness compact metal shell, i.e. the mould shell.The mould shell has accurately copied the shape of prototype, has obtained required mold cavity, after accomplishing aftertreatment technologys such as reinforcement, the demoulding, polishing, can accomplish the quick manufacturing of mould.The manufacturing of electric arc spraying mould generally no longer needs additional machining after accomplishing, and just can directly be used for being shaped making.Also can carry out the numerical control precision work of few cutting output according to practical situation and needs, therefore, the electric arc spraying mold making technology comes down to a kind of " near-net-shape mold making technology ".
The metal spraying mould is standard with the master mold, and mold cavity size, geometric accuracy depend on master mold fully, and mold cavity surface and meticulous decorative pattern thereof once form simultaneously; So molding speed is fast, the manufacturing cycle is short, and cost is low; Have long die life simultaneously; Manufacturing cycle is about the half the of traditional digital control processing, and manufacturing expense can be saved more than 25% at least, becomes the important channel of new product development and small serial production.Mold surface finish is good; Technology is simple; Equipment requirements is low; Relatively be suitable for the quick manufacturing of injection mold, transfer mold, sheet-metal press working mould, complicated and have in blowing, plastic uptake, PVC injection, PU foaming and all kinds of injecting molding die of the various polyurethane products of meticulous decorative pattern in surface shape, the characteristic details that decorative pattern duplicates even can reach 5 μ m.
Oneself is widely used in industries such as aircraft, automobile, household electrical appliances, furniture, shoemaking, artistic handicraft using present this fast mould manufacturing technology.In the U.S. and coastal area of southeastern China, manufacturers has all adopted the electric arc spraying mould to produce on its automatic moulding production unit at the bottom of nearly all polyurethane shoe.In automobile making, can be used for producing wheel, automobile instrument panel, cushion, head cushion, spoiler, automotive trim ceiling etc.In recent years; The electric arc spraying mold making technology has begun to be used to make stamping die of automotive covering part; Spray material is different, and intensity, hardness, precision and the life-span of spraying mould also are not quite similar, thereby range of application also there are differences; The trial-production that is suitable for the automobile sample car that has, have in addition can on production line, substitute traditional steel die and produce.

The metal wire material that is used for electric arc spraying process can be divided into low melting material, fusing point material and materials with high melting point according to the height of fusing point.When making fast mould with arc spraying technology; The thickness of die cavity metal shell will be more than 3mm; After depositing on the master mold, the molten metal particles of middle and high fusing point can discharge more heat transfer; Make master mold generation thermal distortion, reduced the accuracy of repetition of mold cavity, and possibly cause metallic coating that warpage or cracking just take place when not reaching required thickness as yet; Low melting point metal or alloy wire are little to the heat affecting of master mold, can alleviate the influence of molten metal particles to master mold, reduce the master mold thermal distortion, improve the precision of mould, thereby low melting materials such as zinc, Babbitt metal are used for the making of fast mould morely.But the die life of this low melting material is lower; Can only be used for the short run trial production; If will improve the life-span of spraying mould, can on master mold, spray the thermotolerance of one deck low melting material with the enhancing master mold and then spray steel or the higher alloy of other intensity earlier; With the intensity of enhancing mould, thus the life-span of improving mould.
The arc spraying technology of HMP, high hardness material is realized than being easier on metal mother, but at the surperficial mfg. moulding die shell of nonmetal master mold, is had big difficulty on the technology.For example; Refractory metal such as carbon steel, steel alloy when spraying shell shrinking percentage, thermal stresses, porosity all bigger; Shell is easy to crack, warpage, peel off, and the mould shell is made difficulty, and processing parameter control is difficult to grasp; Distortion of mould shell and internal stress are all bigger, can't satisfy the industrial production needs.
The metallic coating of making HMP, high firmness can not rely on hand spray to realize; The temperature etc. of kinematic parameter, electric arc spraying process parameter and the coating and the matrix of nozzle all need accurately be controlled according to specific target in the spraying mould making process, and intelligent arc spraying system is the basic assurance that realizes HMP, high firmness metal arc spraying rapid die-manufacturing.
