The product of forming, Slice Software carry out slicing delamination, and part forming platform declines certain altitude, using power spreading device on platform
One layer of raw material powder is spread, forming first layer is scanned using heat sources such as laser；Platform continues to decline certain altitude, then powdering
It processes to form the second layer again with laser afterwards, so cycle is until form entire part.
Existing laser gain material manufacture powdering bed is using a formation cylinder mostly, and one supplies powder cylinder and scraper plate, leads to
It crosses after rising for powder cylinder and is scraped powder into moulding cylinder using scraper plate, can not only waste a part of powder in this way, but also to powder
Consolidation effect it is poor, this just affects the compactness of drip molding.In addition, traditional powdering bed does not have pre- hot function, rely solely on
Change the parameter regulations heat inputs such as energy and the sweep speed of laser, be unfavorable for taking into account forming, metallurgical quality and production efficiency.

The quality and production efficiency of material manufacture.
A kind of device of laser gain material manufacture powder bed, it is characterised in that including moulding cylinder, for powder case, electric-heat base board, electricity
Machine controller and gas shield cover etc.；Gas shield cover is located on moulding cylinder workbench, by moulding cylinder, for powder case, electric heating base
Plate is placed in gas shield cover；Plunger built in moulding cylinder, plunger base connection plunger drive screw, plunger driving screw rod and plunger
Driving motor is connected, and realizes that plunger moves up and down in moulding cylinder by electric machine controller；It is placed on workbench, leads to for powder case
It crosses for powder case drive screw and controls its straight reciprocating on workbench for powder cylinder driving motor；Electric-heat base board is placed in column
Plug top, passes through heating power supply and temperature controller adjusting control its temperature.
Further, when the confession powder case passes through moulding cylinder open top in table surface sliding process, raw material powder
End exits into moulding cylinder by the bottom gap for powder case；Raw material powder in moulding cylinder is by for raw material powder in powder case
Pressure is acted on and is compacted；With continuing to slide for powder case, the raw material powder layer in moulding cylinder is struck off to form powdering by edge
Layer.
Further, the plunger installed in the moulding cylinder is connect with plunger driving screw rod, and plunger driving screw rod is by column
Driving motor driving is filled in, the action of plunger actuation motor is controlled by electric machine controller, plunger is made to decline certain displacement every time,
So as to control the thickness of powdering layer in moulding cylinder.
Further, the electric-heat base board can adjust laser gain material and manufacture to the pre- heat effect of the generation of powdering layer
The heat input of journey improves forming, metallurgical quality and production efficiency.
Further, the gas shield cover forms enclosure space together with table surface, is opened up above protective cover
Laser beam entrance, side open up air inlet, and laser beam on powdering layer in moulding cylinder, is realized and swashed by laser beam inlet focus
Light increasing material manufacturing process.Argon gas, helium, nitrogen and its mixed gas are entered by air inlet in protective cover, avoid air to laser
The adverse effect of increasing material manufacturing process and product.
The main innovation point of the utility model is will to be combined into one for powder case and scraper plate, simple in structure, and by gravity
Raw material powder powdering is laminated real；Electric-heat base board temperature controllable helps to optimize the technological parameter of laser gain material manufacture, improve
The quality and production efficiency of laser gain material manufacture.
