Three-dimension process model file based on, with liquefaction, powdered, silk can viscous solid material（Such as metal, macromolecule material
Material etc.）, product is successively produced, which has the features such as being limited from part complexity, fully digitalization controls, thoroughly
Traditional manufacture forging, the pattern of machining have been overturned, the industrial mode of production of large-scale production line has been changed, has brought individual character
Change, low consumption, small lot, highly difficult etc. manufacture new concept and new paragon, have the huge meaning for inducing a new industrial revolution,
And the wheel of motor-car is to as motor-car critical component, having high technological requirement, the wheel of motor-car forges main still use at present
The mode made is manufactured, take turns in use once produce breakage both eliminated, if by 3D printing equipment application wheel pair system
Among making and repairing, high-precision, the integrated feature of 3D printing can just meet high request of the motor-car to wheel pair, such as open
Number it is CN105710371A, the time of disclosure is on June 29th, 2016, and entitled " a kind of train wheel plasma 3D printing remanufactures
The Chinese invention patent of device and method ", the equipment by monitoring system, plasma beam system of processing, to train wheel to be repaired
The three axis moving mechanisms and supply what train wheel to be repaired was placed that machining set-up, the drive machining set-up being machined out move
Horizontal stamp pad composition, plasma beam system of processing by plasma generator, print position adjusting apparatus, feeder and
Powder feeder forms；Monitoring system includes moving horizontally controller, temperature detecting unit, distance detection unit, printing distance adjusting
Controller and Rotation Controllers, temperature detecting unit form temperature control device with printing apart from adjustment control device；The present invention is set
Count that reasonable, easy to operate and efficient, using effect is good, without closed molding room, repair process directly under atmospheric environment into
OK, train wheel quality is good after reparation, and remediation efficiency is high, but this technical solution is using three similar to three-dimensional mechanical hand
As printhead and the mobile vehicle of reparation head, design feed in complicated and printing needs to connect by pipeline shaft moving device
Connect, be unfavorable for the scene of a large amount of consumptive material printings, meanwhile, for its process for wheel to integrally carrying out, difficulty of processing is big, if
Standby volume is also big, and the wheel face that the wheel cake of wheel pair is contacted with rail has high requirement, while also has abrasion to require, therefore
Wheel face need not be repaired in general reparation.
The content of the invention：
In order to solve deficiency of the prior art, the present invention provides a kind of method of the 3D printing for refractory metal part.
A kind of method of 3D printing for refractory metal part, it is characterised in that printing step includes as follows：
A. printer is started, in the 3D modeling for the enterprising row metal part of computer being connected with printer；
B. the amount of the data point reuse refractory metal powder obtained according to 3D modeling in step a, refractory metal powder is sprayed into and is fed
Area；
C. melt and spray：The electromagnetic valve adjusted on feed zone makes metal charge at the uniform velocity be melted in melt intracavitary, the liquid of melting
Metal is further melted under the high negative pressure effect between closed chamber and melt chamber by laminar flow plasma jet pipe to be then sprayed into
Enlarged portion；In enlarged portion, flow of liquid metal rapidly increases and is ejected on water-cooling base plate；
D. printing head controls movable spray on high-temperature plane base station by computer, finally obtains refractory metal part.
Refractory metal powder is injected into melt chamber in pulverulence by electromagnetic valve and is melted in the step c.
The operating temperature of the melt chamber is that scope is 1500-61700 DEG C.
The metal charge arrived involved in the step c is refractory metal.
