It is adjusted.
Further, II pars infrasegmentalis nozzle molten metal of inner core output position uses rounding frustum structure, can be with
Molten metal heat loss is effectively reduced, ensures that temperature drop control is in a certain range when silk material sprays.
Further, one or more atmosphere protections are provided with above II section of nozzle molten metal output position of the inner core to lead to
Road, the oxidizing gas that can effectively reduce ejection molten metal enter melt liquid, ensure the quality of final formed metal element.
Further, II section of lower end for being located at I section of wrap of the wrap.
Further, I intersegmental part of the wrap is provided with cooling device, and the type of cooling is circulating cooling, can be effective
The heat for generating heating device and be transmitted to the heat of II section of inner core and quickly disseminate away, so that metal wire material is kept physics shape
State completely realizes continuous wire feed.
Further, II intersegmental part of the wrap is provided with heating device, and the mode of heating of heating device is that resistance adds
Heat or sensing heating, can quickly heat up to the state of melting by metal wire material.
The present invention solves that prior art high energy consumption, nozzle easily block, silk material squeezes out the technical problems such as difficulty.
