Description
Technical field
The present invention relates to 3D printer technology field, particularly relate to a kind of 3D printer piezo jets.
Background technology
3D printing technique originates from the RP technique (RapidPrototyping, RP) occurred the eighties in 20th century.RP technique, also known as free forming technology (FreeformManufacturing, FM).Its general principle belongs to addition manufacture (AdditiveFabrication, AF), neither adopt traditional machining tool and mould, according to three-dimensional computer Computer Aided Design (CAD) model of workpiece, under the control of the computer by free forming machine direct forming 3 D workpiece.It combines the multiple advanced technologies such as CAD, numerical control, material, is a kind of subversive manufacturing technology.Its general principle is, computer software is utilized to carry out hierarchy slicing process to cad model, obtain the two-dimensional silhouette information of each bed boundary, G-code control routine is generated according to profile information, fast forming machine is according to control command, and stratified sedimentation material, forms a series of two-dimensional section lamella, last fast forming machine makes mutually to bond between lamella and lamella, by these thin slices progressively laminated structure be piled into 3 D workpiece entity.Because addition autofrettage is by the three-dimensional conversion to two dimension, the shaping of workpiece is made to become simplification, only need the man-hour of traditional machining 30%-50% and the cost of 20%-35%, just directly can make complicated 3 D workpiece, cause huge repercussion in machinery manufacturing industry.
At present, the cavity inner wall in printer in piezo jets is vulnerable to corrosion, thus causes reduce the service life of piezo jets.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of 3D printer piezo jets.
The present invention is achieved through the following technical solutions:
A kind of 3D printer piezo jets, comprise piezo jets body, cavity is offered in described piezo jets body, the inwall of described cavity is coated with an anticorrosive coat, and liquid inlet is offered on the outside cylinder side of pressure head head body, the bottom surface of pressure head head body is provided with shower nozzle hole, the upper end of described piezo jets body is provided with heat resistant glass plate, and the upper surface of described heat resistant glass plate is provided with lower electrode sheet, the upper surface of described lower electrode sheet is provided with piezoelectric patches, the upper surface of described piezoelectric patches is provided with upper electrode sheet.
As the preferred technical solution of the present invention, described heat resistant glass plate is that transparent material is made, and the thickness of heat resistant glass plate be 3mm ?5mm.
As the preferred technical solution of the present invention, described lower electrode sheet is identical with the thickness of upper electrode sheet.
As the preferred technical solution of the present invention, the thickness of described anticorrosive coat be 1mm ?2mm.
Compared with prior art, the invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, by being provided with anticorrosive coat on the cavity inner wall of piezo jets body, the antiseptic property of piezo jets can be improved, by being provided with heat resistant glass plate, the heat-proof quality of piezo jets can being improved, by being provided with piezoelectric patches between upper electrode sheet and lower electrode sheet, its piezoelectric effect can be improved.
