Description
Technical field
This utility model relates to increasing material manufacturing technology field, a kind of for increasing the digitized spray that material manufactures
Penetrate shower nozzle.
Background technology
Increasing material manufacture is to utilize computer that cad model is separated into series two-dimensional section figure in one direction,
Then the fast method of molding is piled up according to information successively surface.In order to reduce slicer error, generally take
Less slice thickness, the traditional method being improved formed precision by thinning lift height does not only result in shaping speed
Significantly decline, the reduction of moulded products mechanical strength, the technical difficulty of molding is also greatly improved.Molding essence
Degree, speed, cost seriously govern the application popularization increasing material manufacture forming method.In order to solve formed precision
Improve the shaping speed caused and decline problem, it is achieved shaping speed and the Synchronous lifting of formed precision, it would be highly desirable to open
Send the novel injection head that can solve the problems referred to above.
Utility model content
The purpose of this utility model is the deficiency existed for prior art described above, it is provided that a kind of structure
Simply, digitized easy to use injection shower nozzle, digitized injection can be realized in increasing material manufacture process and beat
Print, it is achieved non-homogeneous jet printing, it is achieved shaping speed and the Synchronous lifting of formed precision and non-homogeneous ladder
The increasing material of degree material manufactures.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of for increasing the digitized injection shower nozzle that material manufactures, including micro-nozzle, nozzle hold assembly and injection
Driver part, nozzle hold assembly includes being set in the micropin deck outside the tube wall of micro-nozzle and seat board, micro-
Gluing jet drive parts between pin deck and seat board, micro-nozzle passes from described micropin deck, micro-nozzle
The sheathed lock sleeve in end.
Above-mentioned is a kind of for increasing the digitized injection shower nozzle that material manufactures, and described jet drive parts are that piezoelectricity is made
Dynamic device.
Above-mentioned a kind of for increasing the digitized injection shower nozzle that material manufactures, the tube wall of described micro-nozzle and seat board it
Between be provided with positioning sleeve, be provided with lower positioning sleeve between tube wall and the micropin deck of micro-nozzle.
Above-mentioned is a kind of for increasing the digitized injection shower nozzle that material manufactures, and it is single that described piezoelectric actuator connects control
Unit.
Compared with prior art, this utility model has the following advantages:
1, the tube wall of outside grand drive force micro-nozzle is utilized to move back and forth, by the shearing of miniflow boundary region
The outside grand driving force of viscous force transmission and energy, it is achieved the trace injection of liquid or powder body；The method need not
Micro-embedding microcircuit, it is not necessary to substantial amounts of micro-devices, realizes normality with micro-nozzle self low reynolds number characteristic
Lower closure state；
2, the trace injection realized is digitized injection, and injection frequency, emitted dose size can be adjusted by program
The state modulator such as joint driving voltage.
This utility model can be used for increasing the non-homogeneous injection of same slicing layer during material manufactures, and borderline region uses relatively
High frequency and less emitted dose, the biggest emitted dose in centre, thus realize shaping speed and formed precision
Synchronous lifting and non-homogeneous functionally gradient material (FGM) increasing material manufacture.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model embodiment 1；
Fig. 2 is the schematic diagram of this utility model embodiment 2.
Detailed description of the invention
Embodiment 1
As it is shown in figure 1, a kind of for increasing the digitized injection shower nozzle that material manufactures, micro-nozzle 1 loads micropin card
Seat 5, is being axially and radially located by lower positioning sleeve 6, lock sleeve 7 is being clamped in micropin deck 5, micro-
Pin deck 5 is gluing in piezoelectric actuator 4, and piezoelectric actuator 4 is gluing in seat board 3, piezoelectric actuator 4 by
External control unit controls, and loads upper positioning sleeve 2, support micro-nozzle 1 auxiliary positioning in seat board 3 hole.
During use, the material (liquid or powder body) for molding loads micro-nozzle 1, to piezoelectric actuator 4
Apply pulsed driving voltage, under piezoelectric effect effect, at low level → high level stage, piezoelectric actuator 4
Expand, drive micropin deck 5, micro-nozzle 1 tube wall to accelerate to advance, under boundary region acts on, liquid in pipe
(or powder body) advances with tube wall, the slow pi/2 of phase place.When high level → low level, piezoelectric effect disappears,
Actuator bounces back, and produces backward acceleration, and tube wall reduces and accelerates to retreat, and now liquid (or powder body) exists
Still maintenance advance trend under inertia force effect, produces shearing force, when reaching to be enough to overcome liquid in boundary region
Body tension force, and between tube wall, produce Relative sliding motion, thus realize the pulse fortune of liquid in pipe (or powder body)
Dynamic, to the mouth of pipe, overcome mouth of pipe resistance and liquid tension (or powder body bridge joint power), it is achieved trace sprays.
Under normality, in the micro-pipe of low reynolds number, boundary layer resistance, liquid tension (or powder body bridge joint power) etc. act on
Under, keep liquid in pipe (powder body) not flow, micro-nozzle is in normally off.
Embodiment 2
Single injector 1 shown in Fig. 1 is replaced, it is possible to achieve array sprays with array micro spray mouth, as in figure 2 it is shown,
Array micro spray mouth locks in hopper 41 with screw thread, sealing ring 61 seal, and hopper is bonded in cover plate 31, cover plate
31 gluing and piezoelectric actuators 21, piezoelectric actuator 21 is gluing in seat board 11, above-mentioned droplet jet driving side
Formula is not limited to Piezoelectric Driving, and the energy of all inputs is made with grand type of drive with Digital Control, the energy of input
For outer tube wall, the drop digital driving injection realized by miniflow boundary region belongs to this patent category.
Described in detail above of the present utility model preferably it is embodied as, it will be appreciated that the common skill of this area
Art just can make many modifications and variations according to design of the present utility model without creative work.Therefore,
All those skilled in the art according to this utility model on the basis of prior art by logical analysis, reasoning or
