Description
Technical field
The utility model belongs to metal 3D printing technique field, and in particular to a kind of metal 3D printing powder preheating device.
Background technique
Most basic thought of the metal 3D printing technique based on rapid shaping, i.e., " increment " manufacture of layer-by-layer cladding, root
There is the part of geometry in particular according to three-dimensional CAD model straight forming, metal powder is completely melt in forming process, generates metallurgy
In conjunction with.It is laser fast shaping using the metal parts for the shape and structure complexity that traditional machining means can not manufacture
The Main way of technical application it.
In order to improve the residual stress generated in material forming process by uneven temperature field, common method is to adding
The good drip molding of work carries out subsequent heat treatment, and such part can then undergo the process for first cooling down and heating up afterwards.However, in above-mentioned cooling
In the process, there is deformation, sticks up by the even feelings such as cracking in the building that inside parts are likely to occur stress release and cause power mouth work good
Condition increases the risk for producing substandard products, waste product.Most of all, situations such as deforming, sticking up by even cracking is often in part forming
It just has already appeared in the process, such method controls internal stress in forming process due to lacking, and can not fundamentally solve to ask
Topic.
Summary of the invention
The purpose of this utility model is to provide a kind of metal 3D printing powder preheating device, the powder preheating device heats
Transmission efficiency is high, and preheating is uniform.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is：A kind of metal 3D printing powder preheating
Device, including casing wall pre-heating system and bottom plate pre-heating system, wherein casing wall pre-heating system includes formation cylinder, along formation cylinder outer wall height
Equally distributed N number of heat-insulated cylinder for heating ring and covering formation cylinder bottom and surrounding, the bottom plate pre-heating system packet on degree direction
Include thermal insulation board, the support plate that is mounted on right above thermal insulation board, underface are equipped with heating plate and then install again on the supporting plate
Bottom plate.
Further, annular side's chamber is provided with above support plate, it is intracavitary that heating plate is placed in the party.
Further, thermal insulation board lower part is connected with piston rod, and substrate is mounted on plate upper surface, and metal powder is layered on base
Plate upper surface.
The utility model is also characterized by：The temperature of heating plate reduces with the increase of printing part height, heats ring
It is successively opened from top to bottom with the increase of printing part height, and heating temperature is sequentially reduced from top to bottom.
The utility model has the beneficial effects that：A kind of metal 3D printing powder preheating device, the powder preheating device heat
Transmission efficiency is high, and preheating is uniform.
