Description
Technical field
The present invention relates to the 3D printing technique fields of material extrusion molding, and in particular to a kind of for material extrusion molding
From rolling 3D printing integrated nozzle.
Background technique
3D printing technique refers to print head under program, carries out material filling system according to the cross section information of current layer
It makes, then quickly produces required part by adding up layer by layer again, since it can manufacture arbitrarily complicated part and possess preferably
Printing freedom degree, in industrial production and daily life increasingly have practical 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 can prepare that material ranges are wide, recyclable energy saving, the part lightweight remanufactured of some materials is high-strength because it has
The material characteristics of degree, and being widely used in includes aerospace, defense 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 itself is carried out both at home and abroad
Various performance improvements even more utilize staple fiber, continuous fiber etc. more except the continuous excavation and update crossed for new material
Kind strengthening material realizes the strength enhancing of printout in all directions by the 3D printing of composite material, so far, by planning
Every mechanical index has great promotion in the every single layer of material after the printing of path.
And the 3D printing nozzle of extrusion molding existing for tradition is simply installed at one of the tip of heat block mostly
Runner derived from simple material, major function are forced to squeeze according to channel size when being the friction feeding in print procedure
Out, and the forming situation after squeezing out then is substantially dependent upon the setting of material itself and printing technology parameter, and by the pressure of nozzle
Power influences extremely faint.
Therefore to sum up, it there are the following problems:
One, for extrusion molding material, although can obviously be mentioned by continuous fiber printing or staple fiber pre-preg
Printing intensity of the high one integral piece in single layer can be not accomplish to be obviously improved for binding performance between layers.
Although two, traditional extrusion molding printing nozzle can generate centainly moulding material while material squeezes out
Surface pressing, but the surface pressing that the inherent shortcoming of limitation and the design of its nozzle form generates it is very little, therefore
Bulk density and Jie-for seriously affecting product is micro--receive triple interface performances, so improve product bulk density and multiple interface
Performance guarantees that the overall service performance of 3D printing material extrusion molding product is the problem that another must overcome.
Summary of the invention
In order to overcome deficiency present in the above technology, the purpose of the present invention is to provide one kind to be used for material extrusion molding
From rolling 3D printing integrated nozzle, interlayer performance and each interface performance improvement preferably can be carried out to forming face.
In order to achieve the above object, the present invention adopts the following technical scheme that:
It is a kind of for material extrusion molding from rolling 3D printing integrated nozzle, including nozzle housing 1, 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 mounted on nozzle housing 1
Lower end.
There is nozzle internals fixing screwed hole 104 on the nozzle housing 1, connection spiral shell is equipped with outside 1 upper end of nozzle housing
Line 102,1 upper end of nozzle housing inside are material ball entrance 101, and 1 lower end of nozzle housing is equipped with material delivery outlet 103.
The material input hole 401 and material flowing therethrough slot 405 of connection are equipped with inside the nozzle internals 4, in nozzle internals 4
Equipped with being used to limit the spring annular groove 403 and ball block seat 404 of 2 position of tower spring, ball block seat 404 by with tower spring 2 and spray
Mouth shell 1 is coupled to form a cavity, rotates ball 3 inside it, is equipped in the middle part of nozzle internals 4 solid with nozzle internals
Threaded hole 104 is determined using internals fixing screwed hole 402 in the internals of bolt cooperation, passes through fit with nozzle internals fixing screwed hole
104 and internals on internals fixing screwed hole 402 so that material input hole 401, material flowing therethrough slot 405 in nozzle internals 4 and spray
Material delivery outlet 103 on mouth shell 1 is located at the same side from rolling 3D printing integrated nozzle for extrusion molding.
A kind of rolling 3D printing integrated nozzle certainly for material extrusion molding, installation to 3D printing integrate spray head
Lower section, material then pass sequentially through material ball and enter by being in molten state in the case where 3D printing integrates the temperature control system inside spray head
Mouthfuls 101, material input hole 401, material flowing therethrough slot 405, outside material delivery outlet 103 to nozzle, finally by ball 3 in different bullets
The lower extruding realized under different power of the elastic force effect of the tower spring 2 of property coefficient.
The invention has the benefit that
Using a kind of rolling 3D printing integrated nozzle certainly for material extrusion molding of the 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,
Traditional prints nozzle is extremely improved and performance boost, is had for the 3D printing of extrusion molding material most important
Meaning.
