In forming face, and selectively sinter according to cross section profile information.Metal powder material banging at electron beam
Hit down and be sintered together, and the part formed with lower floor is bonding, piles up layer by layer, until whole part
All sinter.
The power spreading device of conventional electron beam rapidform machine, is mainly put down by dress powder case, Powder spreader, paving powder
Platform and formation cylinder composition.Paving powder platform is in the middle part of operating room, and Powder spreader is movably placed on paving powder platform
Surface.Dress powder case is in the top of operating room, and is hung on the top of paving powder platform.Formation cylinder is in work
Make the bottom of room, and be fixed on the lower surface of paving powder platform.The bottom of formation cylinder is provided with elevating lever, this liter
Fall bar is extended to outside operating room by movable sealing structure.
But, due to the impact of the factor such as gap and particle surface oxidation, metal powder between metal powder material particle
The electric conductivity of material can decline therewith.In electron beam Rapid Prototyping Process, the effect of electron beam can make
Part metals powder particles accumulation electronics and electronegative.Electronegative metal powder material particle has electronics again
When bundle is close, the effect of its Coulomb force will make electronegative metal powder material particle produce displacement, simultaneously
Push neighbouring metal powder material particle open so that metal powder material particle flies out to surrounding centered by beam spot,
Deviation its original piles up position, i.e. produces defeated and dispersed phenomenon (being commonly called as " blowing powder ").Defeated and dispersed phenomenon can cause work
Part forming dimension error, What is more is likely to result in shaping unsuccessfully.
Utility model content
Technical problem to be solved in the utility model is that the power spreading device of existing electron beam rapidform machine is deposited
The problem affecting component shaping in the defeated and dispersed phenomenon of metal powder material particle, it is provided that a kind of electron beam rapid shaping
