Description
Technical field
The utility model relates to 3D printing technique field more particularly to a kind of continuous extruded type ceramics 3D printing extrusion devices
Fixed structure.
Background technique
Ceramic material is with its lightweight, high intensity, high temperature resistant and the excellent speciality such as corrosion-resistant in aerospace, the energy, electronics
The fields such as information and biomedicine have obtained extensive and important application, but due to the unworkability of ceramics, in traditional handicraft
Shaping for complicated ceramic part becomes the critical issue for hindering high performance ceramic material application.Using advanced forming technology system
Making complex parts becomes the emphasis of recent ceramic material research field, wherein the appearance based on extrusion molding ceramics 3D printing technique
Very more concerns has been obtained, has been expected to solve the problems, such as that complicated shape ceramic part shapes.The technique is former based on discrete-accumulation
The rapid prototyping technology of reason, it, which can be not required to mold and tool, can be quickly obtained part.In forming process, it will prepare first
Ceramic paste be packed into barrel, ceramic paste under the action of extruding force from extruder head squeeze out, being deposited in can move down along Z axis
Dynamic table surface, extruder head are moved along the direction X-Y under control of the control system, are layering, and ultimately form ceramic system
Part.Wherein, extrusion device is the core of entire former, but extrusion system is seldom able to achieve continuous extrusion at present, forming compared with
Big components need biggish barrel, meanwhile, the reliability fixation of extrusion device determines extrusion quality.Therefore, how to realize
The reliability of extrusion device is fixed and is continuously squeezed out and is a technical problem that technical personnel in the field need to solve at present.
Utility model content
The utility model is to solve technical problem present in well-known technique and provide a kind of continuous extruded type ceramics 3D and beat
Print the fixed structure of extrusion device.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: a kind of extruded type
Ceramic 3D printing extrusion device includes: pedestal, front end fixing piece, conveying pipeline, fast joint, barrel front end retaining ring, barrel, barrel branch
Support fixing piece, piston, push rod and driving part.
Front end fixing piece and barrel support fixing piece are located on pedestal, on the fixed front end fixing piece of barrel front end retaining ring, material
Cylinder is by barrel support fixing piece support and clamps, and barrel front end holds out against barrel front end retaining ring；Push rod under the driving of driving part,
Piston is pushed to squeeze out the ceramic paste in barrel, conveying pipeline is connected with barrel by fast joint.
Preferably, the barrel support fixing piece cyclic structure fine-tuning using Automatic-clamping, position.
Preferably, the barrel baffle chamfer angle is identical as barrel toe angle.
Preferably, the barrel discharge end is connected with the ceramic paste conveying pipeline by the fast joint.
Preferably, the barrel support fixing piece uses two symmetrical structures.
The utility model has the advantages and positive effects of:
(1) barrel by barrel support fixing piece support and clamps, and barrel supports fixing piece can be micro- using Automatic-clamping, position
The cyclic structure of tune, on the one hand ensure that barrel and push-rod piston to neutrality, go on smoothly extrusion process, on the other hand make
Obtaining barrel has certain non-moving ability along axial direction, so that barrel is not with movement when push-rod piston pumpback.
(2) barrel front end retaining ring is fixed on the fixing piece of front end, ensure that the stability of barrel front end retaining ring.
(3) barrel front end holds out against barrel front end retaining ring, and barrel baffle chamfer angle is identical as barrel toe angle, reduces
The stress of barrel front end is concentrated, while ensure that the immovability of barrel, improve entire extrusion device stability and
Reliability.
(4) barrel discharge end is connected with ceramic paste conveying pipeline by fast joint, and quick-replaceable can be realized by squeezing out barrel, real
The continuous extrusion of existing material.
(5) two symmetrical barrel support fixing pieces ensure that the levelness of barrel and the distributing homogeneity of power.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, pedestal, 2, front end fixing piece, 3, conveying pipeline, 4, fast joint, 5, barrel front end retaining ring, 6, barrel, 7, material
Cylinder support fixing piece, 8, piston, 9, push rod, 10, driving part.
Specific embodiment
For the utility model content, feature and effect that can further appreciate that the utility model, the following examples are hereby given, and
It is described in detail with the accompanying drawings as follows:
As shown in Figure 1, a kind of extruded type ceramics 3D printing extrusion device provided by the utility model, including pedestal 1, front end
Fixing piece 2, conveying pipeline 3, fast joint 4, barrel front end retaining ring 5, barrel 6, barrel support fixing piece 7, piston 8, push rod 9 and driving
Component 10.
Front end fixing piece is connect by bolt with pedestal with barrel support fixing piece, and barrel front end retaining ring is bolted
It is fixed on the fixing piece of front end.The barrel for filling ceramic paste is put in barrel support fixing piece, barrel front end retaining ring is held out against,
Barrel supports fixing piece Automatic-clamping barrel, while finely tuning the position of barrel.Piston and push rod pass through interference fit connection, push rod
Under the driving of driving part, piston is pushed to squeeze out the ceramic paste in barrel with certain speed, ceramic paste is through discharging
Pipe reaches extruder head, and the ceramics of extrusion are layering, and dry solidification shapes in air.When the ceramic paste in barrel is complete
When extrusion, the connection of discharge nozzle and crossover sub is disconnected, the expects pipe more renewed realizes continuous extrusion molding.This extrusion device
Fixed structure has many advantages, such as reliability, stability, economy, and energy；Continuous extrusion molding, substantially increases the utility model
Versatility, save time and cost.
Although being described above in conjunction with preferred embodiment of the attached drawing to the utility model, the utility model is not
