Description
Technical field
The present invention relates to the 3D printing technique field of material extrusion molding, and in particular to a kind of for material extrusion molding
From rolling 3D printing integrated nozzle.
Background technology
3D printing technique refers to printhead under program, and carrying out material filling according to the cross section information of current layer makes
Make, then quickly produce required part by adding up layer by layer again, because it can manufacture arbitrarily complicated part and possess preferably
The printing free degree, in industrial production and daily life increasingly have actual application value.
As an important branch in 3D printing field, the 3D printing of extrudable moulding material is increasingly learned both at home and abroad
The attention of person, because it possesses, can to prepare wide material ranges, the recyclable energy saving remanufactured of portion of material, part lightweight high-strength
The material characteristicses of degree, and be widely used in including Aero-Space, national defense and military, medical industry, industry spot and robot, clothes
Multiple fields including industry of being engaged in.And in order to improve the 3D printing of extrudable moulding material, printed material is carried out in itself both at home and abroad
Many performance improvements are even more more using chopped fiber, continuous fiber etc. except the continuous excavation and renewal crossed for new material
Plant strengthening material and the strength enhancing of printout in all directions is realized by the 3D printing of composite, so far, by planning
Every mechanical index has great lifting in the every individual layer of material after the printing of path.
And sophisticated one of heat block is simply installed at mostly for the 3D printing nozzle of traditional existing extrusion molding
Runner derived from simple material, its major function is forced to squeeze according to channel size when being the friction feeding in print procedure
Go out, and the shaping situation after extruding then be substantially dependent upon material in itself and printing technology parameter setting, and by the pressure of nozzle
Power influence is extremely faint.
Therefore to sum up, there is also problems with for it：
First, for extrusion molding material, although can substantially be carried by continuous fiber printing or chopped fiber pre-preg
Printing intensity of the high one integral piece in individual layer, can be not accomplish to be obviously improved for binding ability between layers.
Although the 2, traditional extrusion molding printing nozzle can be produced necessarily while material is extruded to moulding material
Surface pressing, but the inherent shortcoming of limitation and the design of its nozzle form make it that the surface pressing that it is produced is very little, therefore
Have a strong impact on product bulk density and Jie it is-micro--receive triple interface performances, so improving the bulk density of product and multiple boundary
Face performance, it is ensured that the overall performance of 3D printing material extrusion molding product is the problem that another must pull against.
The content of the invention
It is not enough present in above technology in order to overcome, it is used for material extrusion molding it is an object of the invention to provide one kind
From rolling 3D printing integrated nozzle, can be preferably to forming face progress interlayer performance and each interface performance improvement.
In order to achieve the above object, the present invention is adopted the following technical scheme that：
In a kind of rolling 3D printing integrated nozzle, including nozzle housing 1 certainly for material extrusion molding, nozzle housing 1
Portion is fixed with nozzle internals 4, and the tower spring 2 and ball 3 that nozzle internals 4 are arranged right below connect, and ball 3 is arranged on nozzle housing 1
Lower end.
Have on described nozzle housing 1 outside nozzle internals fixing screwed hole 104, the upper end of nozzle housing 1 provided with connection spiral shell
It is material ball entrance 101 inside line 102, the upper end of nozzle housing 1, the lower end of nozzle housing 1 is provided with material delivery outlet 103.
The material input hole 401 and material flowing therethrough groove 405 being communicated with inside described nozzle internals 4, nozzle internals 4
Be provided with and be used for limiting the spring annular groove 403 of the position of tower spring 2, and ball block seat 404, ball block seat 404 by with tower spring 2 and
Nozzle housing 1, which coordinates to install, forms a cavity volume, makes ball 3 in its inner rotation, the middle part of nozzle internals 4 is provided with and nozzle internals
Fixing screwed hole 104 passes through fit with nozzle internals fixing screwed hole using internals fixing screwed hole 402 in the internals of bolt cooperation
104 and internals on internals fixing screwed hole 402 so that material input hole 401, material flowing therethrough groove 405 in nozzle internals 4 and spray
Material delivery outlet 103 on mouth shell 1, which is located at this, is used for the same side from rolling 3D printing integrated nozzle of extrusion molding.
A kind of described rolling 3D printing integrated nozzle certainly for material extrusion molding, is attached to the integrated shower nozzle of 3D printing
Lower section, material then passes sequentially through material ball and entered by being in molten state under the temperature control system inside the integrated shower nozzle of 3D printing
Mouthfuls 101, material input hole 401, material flowing therethrough groove 405, outside material delivery outlet 103 to nozzle, eventually pass ball 3 in different bullets
The extruding under different power is realized under the elastic force effect of the tower spring 2 of property coefficient.
Beneficial effects of the present invention are：
Using a kind of rolling 3D printing integrated nozzle certainly for material extrusion molding of the present invention, ball 3 can be passed through
The characteristic of servo-actuated rolling effectively improves Coating combination performance, print density and the every interface performance of extrusion molding 3D printing,
It is extremely improved for traditional prints nozzle and performance boost, has most important for the 3D printing of extrusion molding material
Meaning.
