Description
Technical field
The present invention relates to a kind of fusion sediment 3D printing wire rod wiring device assemblies, belong to FDM (fused glass pellet) 3D
Printing field.
Background technique
3D printing technique, also referred to as AM(increasing material manufacturing), scientific research, industrial production and height are had been widely used at present
Smart point processing and other fields.The technology basic process are as follows: pre-designed by CAD(CAD) model, it is beaten using 3D
Print control system (computer) carries out sliding-model control to it, obtains one group of 2-D data information for corresponding to threedimensional model；So
3D printer is driven with 2-D data information afterwards, finally obtains complete 3D solid in such a way that lamination is accumulated.FDM printing
Technology belongs to extruded type 3D printing technique major class, is a kind of common and widely applied 3D printing technique.The technology is usually
Thermoplasticity wire rod is delivered to through wire feeding system and is squeezed out at spray head, is heated to half melt in the showerhead, then squeeze out and is being worked
3D solid is constructed on platform.
The thermoplasticity wire rod of mainstream includes: PLA(polylactic acid currently on the market), ABS(acrylonitrile-styrene plastics), PC
(polycarbonate), HIPS(high impact polystyrene) and PA(nylon) etc., it also include the function that a part is used for specific use
The wire rod of energyization.The primary diameters of wire rod have 1.75mm and 3.00mm, match with common FDM print system.
FDM is printed upon mold, handicraft model, component of machine etc. extensive use, but shaping speed is slower, line
Material consumption is big, so that it faces huge challenge in large-sized object during constructing.In addition, the more file printings of FDM also by
Gradually become the market demand, but current FDM is mainly single nozzle and double spray heads, meeting more file printings, there is also certain
It is difficult.And the key to solve the above problems is to can be realized easy flexible docking between FDM wire rod.General solution
Have and directly cut flat with wire tip, be attached by way of directly heating perhaps glue bonding then again with blade or
Sand paper carries out cutting polishing, to be adapted to FDM extruder head.This method is inconvenient, of poor quality at wire rod docking, is easily broken off,
Influence the quality of printed product.Have been reported that some tools for the docking of FDM wire rod at present, such as a kind of similar to vice
Heated jig can be realized wire rod docking, but its is inconvenient, and technical process is cumbersome, still needs at the docking of final wire rod
Want grinding process.Patent CN201610488811.X discloses a kind of FDM 3D printer consumptive material attachment device and its user
Method.The invention specifically includes dismountable first fixed part and the second fixed part, first fixed part and the second fixed part
Splicing constitutes the first passage and second channel passed through for 3D printing wire rod, first passage and second channel after being fixed together
Between for for heat wire rod butt end working region.Although the invention may be implemented preferable wire rod and connect, but wire rod
It is to be heated in the case where exposure at docking, using open fire or other heating methods, until fusing, finally needs hand
It is dynamic to be pushed into be cooled down in corresponding channel, also need the later period to be slightly trimmed in the wire rod connected suitably sized for FDM
Printing.Whole operation technique is relatively complicated, inconvenience be used as the matched tool of FDM printer, the heating method of open fire make its
There are security risks in use process.Further, since the melting temperature of different materials has differences, the party is utilized to limit
Method realizes wire rod docking not of the same race.
To sum up, now there is an urgent need to it is a kind of integration, tool FDM wire rod attachment device, while require it is easy to operate,
It is highly-safe, it can satisfy a variety of wire rod connection requests, be suitble to marketing application.
Summary of the invention
