Description
Technical field
The utility model relates to the mould in a kind of metalworking technology field, specifically is a kind of diamond composite coating drawing mould with multi-layer film structure.
Background technology
Drawing mould is the most critical link that cable products is produced, directly influence raising and raw-material effective saving of relevant industries production efficiency and product quality, metal drawing and strand system are the most general processing technologys of metal material, wire drawing die, pressing mould and other various drawing moulds is power cables, metallic article, the crucial mould that industries such as building pipe are commonly used, applied range, market capacity is big, this occupies quite great proportion in the tool and mould field its mould manufacturing, go up the traditional carbide alloy drawing mould that extensively adopts yet produce at present, mould is very easy to wearing and tearing, life-span is short, the mould loss is big, production efficiency is low, and draw and strand system product surface quality poor, particularly the sectional dimension precision is difficult to guarantee, causes waste of raw materials serious, has seriously restricted the technological progress of conventional industries and the further raising of industry benefit.And because tungsten is again a kind of strategic materials, the consumption of a large amount of mould Hardmetal materials directly causes the waste of national strategy material tungsten resource.
Characteristics such as high temperature resistant, wear-resistant, anti-oxidant, corrosion-resistant and good elevated temperature strength that engineering ceramic material has just are applied in many fields of in the past using carbide alloy at present.Along with the impact strength and the fracture toughness of advanced ceramics increases substantially, be hopeful to develop into the desirable alternative mould of carbide alloy drawing mould most.Chemical vapor deposition diamond film has a series of excellent properties, it has very near the hardness of natural diamond, high elastic modelling quantity, high thermal conductivity, low excellent properties such as coefficient of friction, low thermal coefficient of expansion and chemical stability, thereby is with a wide range of applications in the tool and mould field.For the non-oxidized substance structural ceramics, as carborundum (SiC), silicon nitride (Si
3N
4) etc., the strong carbide that is typical strong covalent bond combination forms material, be similar to adamantine tetrahedral structural unit, on above-mentioned ceramic matrix, the CVD diamond nucleation density is big, with diamond coatings good associativity is arranged, compare with carbide alloy, the ceramic material thermal coefficient of expansion is less, the graphitization of urging of not having Co again influences, therefore, and on ceramic matrix material, obtain the diamond coatings that bond strength significantly improves than carbide alloy easily, thereby efficiently solve this technical barrier of anchoring strength of coating.Therefore a kind of innovative idea is exactly the advantage in conjunction with ceramic die and diamond thin, adopt chemical gaseous phase depositing process, at the diamond coated film of drawing mould bore area, preparation ceramic base diamond coatings drawing mould is in order to service life of prolonging traditional moulds, enhance productivity and improve the quality that product is made in drawings, strand.Simultaneously to raw-material saving such as copper with to reduce the consumption of tungsten resource also significant.
The CVD diamond mixes the electric conductivity that boron element not only can improve film, and a spot of boron element joins in the diamond and can also improve quality and surface topography by film, increase along with boron doping concentration, the average grain size of film reduces, and planar defect density obviously descends, thereby has improved quality of diamond film.The adding of boron element has significantly changed adamantine forming core speed, suitable boron doping concentration significantly increases diamond film speed, this patent is a raw material with acetone and hydrogen, with the trimethylborate is doped source, preparation boron-doped diamond film composite coating has important function for increase diamond film speed, refinement diamond thin crystal grain, reduction film internal stress, raising film quality.
Find through retrieval prior art, number of patent application 200810044524.5, publication number CN101280423A, put down in writing a kind of " manufacturing method of small aperture diamond coating drawing die ", adopt on the vertical direction and arrange heated filament, after heated filament passes nib, stretching with the taper weight, high temperature spring buffering gravity; Adopt the uniform anchor clamps fixed mould of hoop, the interlock effect of the uniform anchor clamps of hoop is positioned on the heated filament direction mold axis of different profile specifications, and uniform in addition anchor clamps have the effect of even cooling, and the quality of diamond coatings and uniformity are guaranteed.But the prior art adopts substrate to remain WC-Co cemented carbide substrate material, because Co urges graphitizing and influence factors such as carbide alloy and diamond thin thermal expansion coefficient difference, make and exist bigger thermal stress in the diamond coatings, cause between diamond thin and the matrix material bond strength to be still waiting to improve, because substrate remains carbide alloy, exists the pressure that tungsten, cobalt resource consumption and manufacturing cost improve constantly equally.
