Change system shapes powdering doctor blade device.
Background technology
" 3D printing " technology, also referred to as increment manufacturing technology, result from the U.S. of the eighties of last century eighties, CAD (computers
Computer Aided Design), CNC (Digital Control), automatically control, the development of the technology such as laser is cause that it is produced, develop so far not
By 30 years." 3D printing " technology is light harvesting/machine/electricity, computer, numerical control and the new material that global advanced manufacture field is risen
In the manufacturing technology of one.In this field, the technological gap between China and World Developed Countries is smaller, is nearly seated at together
Run on line.Why it is referred to as increment manufacture, different according to material " removal " manufacturing process such as itself and traditional cutting, the technology is led to
Cross and successively accumulate the dispersed materials such as powder, liquid, thin slice, " naturally grow " is called that " 3D is beaten into 3D solid, therefore by popular
Print " technology.3D solid monolithic molding is changed into the superposition forming of some two dimensional surfaces by the technology, greatly reduces manufacture
Complexity.In theory, as long as the structural model that can be designed on computers, you can the application technology is without cutter, mould
And prototype is rapidly changed into kind under the conditions of complicated technology.At present, the technology is in national defence, Aero-Space, automobile, biology
The fields such as medical science, mould, casting, agricultural, household electrical appliances, industrial art, animation play an important role.
Following manufacturing development level is still one of key point of the national overall strength of measurement one, and future makes
Technology is made under the drive that the corresponding technologies such as Numeric Control Technology, computer, machinery, material develop, inevitable trend digitlization and intelligence
Change." 3D printing " technology is as digitlization among whole advanced manufacturing technology and the intelligent class more protruded, and it develops
Influence can be profoundly monolithically fabricated on manufacturing industry in different aspects.First, the application field of " 3D printing " technology will constantly expand
(range)；Secondly, " 3D printing " technology deepens continuously (depth) in the application of each application field；Furthermore, 3D printing skill

Embodiment
In order that technical problem, technical scheme and beneficial effect that the utility model is solved are more clearly understood, below
With reference to drawings and Examples, the utility model is further elaborated.It should be appreciated that specific implementation described herein
Example only to explain the utility model, is not used to limit the utility model.
With reference to Fig. 1-Fig. 3, the utility model provides a kind of precinct laser fusion system shaping powdering doctor blade device, including solid
Fixed board 1, movable support frame 2, elastic parts 3, scraper 4 and doctor blade holder 5；Wherein, elastic parts 3 includes spring 3.1, guide rail
3.2nd, sliding block 3.3 and jackscrew 3.4；
At least one spring 3.1 is fixedly mounted in the lower section of the side of movable support frame 2；In figure 3,3 springs are installed altogether；
The top assembling jackscrew 3.4 of the side of movable support frame 2；Mounting plate 1 is clamped between spring 3.1 and jackscrew 3.4；Jackscrew
3.4 elongation is adjustable, and then adjusts the decrement of spring 3.1；
The guide rail 3.2 of plumbness is also fixedly mounted in the side of movable support frame 2, and sliding block 3.3 is slidably sheathed on guide rail 3.2
On；Fixed plate 1 is fixedly connected with sliding block 3.3；
Scraper 4 is fixedly installed in the bottom of movable support frame 2 by doctor blade holder 5；The knife-edge part of scraper 4 has fillet, circle
Angle is used for when powdering scraper touches raised points, it is produced upward component.When scraper 4 touch raised points and produce to
On component when, promote the overall direction relative to fixed plate 1 along guide rail 3.2 of movable support frame 2 to pop up.
The powdering doctor blade device that the utility model is provided, its operation principle is：
Fixed plate 1 is scraped driving device for cutter with powdering and is assembled together, and driving device for cutter driving powdering scraper dress is scraped in powdering
Put overall during formation of parts surface progress powdering, the movement of 1 progress horizontal direction of fixed plate will not occur vertical
The motion in direction.When scraper 4 is touching raised points during powdering, upward component is produced；Upward component can be promoted
Movable support frame 2 is popped up relative to fixed plate 1.Herein, the effect of spring and jackscrew, makes movable support frame 2 relative to solid
Fixed board 1 has the free degree popped up；Also, the elongation of jackscrew can adjust, when jackscrew elongation is adjusted, bullet can control
