Abstract
The invention discloses a method for manufacturing additives based on synchronous spray and adhesion. The method includes the steps that according to the requirement for the appearance of a part to be formed, a three-dimensional model of the part to be formed is established, and hierarchical processing is conducted according to the machining direction; according to the requirement of the three-dimensional model for the number of base materials and adhesives, base material particles and the adhesives are placed in a powder feeder and an adhesive container respectively, compressed air directly carries the base material particles from the powder feeder without preheating and then conveys the base material particles to a base material spray gun, and meanwhile an adhesive spray gun is controlled to spray the adhesives to conduct adhesive solidification on the base materials; according to the shape of each layer section of the three-dimensional model, relative motion of the spray guns and a platform is controlled, and layer-by-layer multi-material controllable spray forming is conducted; after spray and adhesive forming of the part to be formed, a small number of particle materials which do not adhere to the surface and the internal structure are removed, and a final part to be formed is formed. According to the method, spray of the base materials and spray of the adhesives for adhesive solidification can be conducted at the same time, and the method has the advantages that the base materials are saved, cleaning is easy to conduct, energy is saved and emission is reduced.
Description
Technical field
The invention belongs to and increase material manufacturing technology field, particularly a kind of increasing material manufacture method of synchronous spraying and adhesive bonding.
Background technology
Increasing material manufacturing technology, to take metal, plastics and pottery etc. be primary raw material, forward labyrinth, multiduty integrated quick manufacturing direction development.Follow " multi-shell curing; cumulative layer by layer " know-why, according to mode curing in layer, common increasing material manufacturing technology can be able to be divided three classes: the first kind is light stationary, as stereolithography technology (SL), be subject to ultraviolet ray etc. irradiation scan, make photocurable liquid polymer because of photopolymerization, harden into thin layer; Equations of The Second Kind is thermosetting formula, comprises fuse Deposition Modeling (FDM), precinct laser sintering (SLS), electron beam melting (EBM), and the melting and refreezing of all take is basic principle admittedly, material is melted and be solidified togather formation thin layer; The 3rd class is mucosity type, as 3-D spraying binding (3DP), laminated solid body manufacture (LOM), is dusty material to be optionally bonded to as a whole, or will layer material along edge cuts, forms required cross sectional shape after bonding.
As mentioned above, the processing object narrow range of light stationary, is only applicable to photocurable liquid polymer, and must be equipped with the light emitters of corresponding wavelength or frequency; Thermosetting formula, because all material all will become process through solid-liquid-solid phase, causes change in volume large, and residual stress and distortion are large and need high power laser equipment, and cost is higher, and molten long-pending efficiency is low; Mucosity type is used laser cutting system possibly, and equipment cost is higher, should not control the spraying of bonding agent, though contact the material of bonding agent, can not reuse, and during cleaning, easily causes powder fly upward and be detrimental to health.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of increasing material manufacture method of synchronous spraying and adhesive bonding, take micro-, nano level metal, plastics or ceramic particle is base material, and the method that adopts two spray guns that spray respectively base material and bonding agent to be synchronized with the movement is manufactured complex-shaped part fast; Can realize and when spraying base material, spray bonding agent and binds and solidify, there is the base material of saving, be easy to clear up, energy-saving and emission-reduction.
To achieve these goals, the technical solution used in the present invention is:
An increasing material manufacture method for synchronous spraying and adhesive bonding, comprising:
1), according to the shape requirement of to be formed, build its threedimensional model, and carry out layering processing according to machine direction;
2) demand to base material and bonding agent quantity according to threedimensional model, substrate particles and bonding agent are positioned over respectively in powder feeder and bonding agent container, without preheating, Compressed Gas directly carries substrate particles in powder feeder, be delivered to base material spray gun, and control bonding agent spray gun and spray bonding agent simultaneously base material is binded and solidified;
3) according to the every layer cross section shape of threedimensional model, control the relative motion of spray gun and platform, the controllable spray that carries out many materials is successively shaped;
4), after to be formed injection bonding shaping, on cleaning Surface and internal structure, a small amount of not granular materials of bonding, forms final to be formed.
Described base material spray gun and bonding agent spray gun are controlled by isochronous controller, are synchronized with the movement, and substrate particles and bonding agent are injected on platform or cured layer simultaneously and instantaneous bonding is shaped.
The substrate material adopting comprises one or more of metallic particles, plastic grain and ceramic particle.
Compared with prior art, increasing material manufacture method based on synchronous spraying and adhesive bonding technology provided by the invention, the method that adopts base material spray gun and bonding agent spray gun to be synchronized with the movement is carried out the manufacture of part, can realize and when spraying base material, spray bonding agent and binds and solidify, there is the base material of saving, be easy to clear up, energy-saving and emission-reduction.
