Description

A kind of method and its series 3D printing metal powder of increase and decrease material manufacture engraving knife die
Technical field
The invention belongs to cutting die molding fabrication techniques field, it is related to a kind of method of increase and decrease material manufacture engraving knife die and its is Column 3D printing metal powder, in particular to a kind of manufactured based on the increase and decrease material of metal 3D printing and high-precision automatic engraving technology are carved The method of icking tool mould and its serial 3D printing metal powder.
Background technique
Mold plays very important effect in contemporary industry production field, injection molding, blow molding, extrusion in industrial production, Die casting or the methods of forging and forming, smelting, punching press require mainly to pass through changing for physical state of the formed material using to mold Become the processing to realize article shape, is known as the title of " mother of industry ".Cutting die is more commonly used product in cross cutting industry, It is generally used for stamping out the shape of required die cutting product, outside printing packaging, plastics package, leather, toy, automobile, mobile phone Shell, flexible circuit board etc. have important application, product can be made to carry out efficient mass production by cutting die, avoided The inefficiency problem manufactured one by one.Cutting die be broadly divided into laser cutter mould, engraving knife die, aluminium sheet cutting die, etching cutting die, cutting die, Stripping cutting die etc., wherein engraving knife die and laser cutter mould are the most commonly used, and cutting die precision is higher, and service life is longer.Laser Cutting die mainly carries out high depth ablation to cutting die plate using the strong energy of laser, to achieve the purpose that install cutter.Swash Light-knife die cutter processes cutting die technique, and with designing, simple, error is small, work efficiency is high.Relative to laser cutter mould, graver The precision of mould is higher, can be controlled in ± 0.03MM, and the precision of laser cutter mould is in ± 0.1MM.Haveing excellent performance for engraving knife die, can It bears with high punching press number, and can repeatedly study for a second time courses one has flunked the knife edge.It but is knife because its precision is high, the advantages that being unlikely to deform Film forms preferable method.
Engraving knife die substrate is generally adopted by planar substrates, is produced by impacting one by one on machined material Operation, in order to further increase production efficiency, planar substrates are gradually replaced cylindrical base, i.e., in the arch of cylindrical base The knife edge is processed on face, this kind of engraving knife die is known as (dise knife), processes by way of rolling " printing " to rapidoprint Production, the working efficiency that roller operating efficiency significantly larger than impacts one by one.But the process time of engraving knife die compares laser cutter mould More 2 times or more are wanted, it includes the wire cutting of shape and the processing of material-dropping hole that traditional engraving knife die, which will carry out substrate wire cutting, is gone back later Carry out numerically-controlled machine tool roughing, numerically-controlled machine tool is according to designed cutting die model by knife edge part from entirely cutting come (can To be worked into knife line width as 0.5mm), even if the initial knife edge of the mold of cutting die can be highlighted on substrate in the form of embossment, it is The sharpness of the knife edge of later period finishing and the finish of knife edge side provide basis；Then need by working continuously to initial Engraving knife die carries out multiple vacuum high-temperature heat treatment, promotes the hardness of initial cutting die (not less than 50HRC)；Finally make again With numerical control machine tool, to treated, initial cutting die carries out retrofit, carries out last knife edge processing and forming, makes cutting die The knife edge is sharp, any surface finish, finally obtains engraving knife die finished product.Initial knife edge forming process is needed the region of non-blade position Fully erased, the removing of one side large area causes a large amount of wastes of material, and difficulty of processing is also therefore elongated with the period.Another party Face, it is poor that a large amount of cutting removing causes working environment.It simultaneously must be to initial in order to make cutting die reach ideal grade Cutting die carries out multiple high temp heat treatment, and the high-temperature heat treatment period is longer, and heat treatment process considerably increases engraving knife die Manufacturing cycle, heat treatment operation process is more stringent, increases difficulty to engraving knife die manufacturing process.
Metal 3D printing is the direction that have developed rapidly in recent years, very high using valence in having for material increasing field Value, many metal 3D printing equipment can produce strong cured type structure devices, stress member and functor at present, become 3D printing The technology of manufacture is most possibly directly used in field, application field spreads aerospace, health care, instrument manufacturing, electricity Sub-industry etc..Metal 3D printing is divided into Selective Laser Sintering (SLS), selective laser melting technology (SLM), directly gold Belong to exciting sintering technology (DMLS) and laser engineering purification molding (LENS), laser powder molding (LPF) etc..Wherein select Property laser melting process (SLM) with and laser engineering purification molding (LENS) metal 3D printing field achieve well at Effect, SLM are then to use superlaser by the way that powder body material laying on the table, and is heated the material to certain temperature Beam melts powder body material, and cladding material and matrix form very strong metallurgical bonding, and the powder body material not being scanned still at The powdered support as workpiece, after one layer of scanning is completed, workbench declines a layer height, and carries out next layer of powdering, weight The multiple above process is completed three-dimensionally shaped.Selective laser melting technology (SLM) precision with higher, compactness up to 100%, Suitable for complicated, high-performance metal device, and there is very high shaping speed and shaping efficiency.Laser engineering purification molding (LENS) different from selective laser melting technology (SLM), in laser engineering purification molding (LENS) technique, laser irradiation nozzle The powder stream of conveying, i.e. laser are worked at the same time with conveying powder, cladding material are sent directly into laser, therefore do not need SLM Workbench equipped with powder.LENS also possesses higher formed precision, and it is three-dimensional to be also applied for complicated high performance metal Molding, while can also guarantee preferable shaping efficiency.
Cladding layer cladding is set to exist by cladding principle adjustable high rigidity metal powder by metal 3D printing technique The initial knife edge is formed on substrate, then the initial knife edge that cladding layer is constituted is subjected to numerically-controlled machine tool finishing, engraving knife die can be completed Manufacturing process.Full-automatic high-precision control system is that the precision of engraving knife die provides a strong guarantee.Pass through metal 3D printing The initial knife edge that cladding is formed, which avoids, reduces cost of manufacture and fabrication cycle, reduces environmental pollution.The initial knife edge of cladding High rigidity characteristic, improve its hardness without carrying out the operation of multiple vacuum heat treatment, this process not only further shortens Process-cycle, but also processing cost is minimized.
A kind of manufactured based on the increase and decrease material of metal 3D printing and high-precision automatic engraving technology proposed by the present invention is carved The method of cutting die and its serial 3D printing metal powder are a kind of economic, efficiently, environmentally friendly engraving knife die manufacturing technology methods, are being protected While properties needed for demonstrate,proving cutting die, reduces wastage of material and fabrication cycle, avoid complicated for operation, operation difficulty mistake Big problem.More preferably method is provided for engraving knife die molding, possesses very high market application prospect and market price Value, and the manufacturing technology of engraving knife die is innovated with metal 3D printing using important in inhibiting.
