Description
Technical field
The utility model belongs to laser forming technical field, and in particular to a kind of selective laser fusing hilted broadsword two-way powder laying dress
It sets.
Background technology
Selective laser fusing SLM is a kind of method of metalwork straight forming, is the latest development of rapid shaping technique.It should
Most basic thought of the technology based on rapid shaping, i.e. " increment " manufacture of successively cladding, according to three-dimensional CAD model directly at
Type has the part of geometry in particular, and metal powder is completely melt in forming process, generates metallurgical binding.Using traditional machine
The metal parts for the shape and structure complexity that manufacturing process can not manufacture is the Main way of rapid laser-shaping technique application
One of.
Existing selective laser fusing SLM device is divided into two kinds of unidirectional powdering and two-way powder laying in the way of powdering.Wherein,
Unidirectional powdering equipment is needed using twin-tub form, powdering scraper across two cylinders, and only shot.It is spreading every time
Before powder, then scraper executes powdering firstly the need of initial position is moved to.This powdering mechanism efficiency is low, and it is long to expend the time
And powdering effect is limited by single powder supply amount.
Nowadays, fusing SLM device in selective laser has used more efficient two-way powder laying device, this one kind to set mostly
Standby only to retain a formation cylinder, power spreading device carries out two-pass powdering.According to the quantity for using scraper, existing two-way powder laying device
Single doctor mode device and double doctor mode device two types can be further divided into again.Wherein, in double doctor mode devices
Between there are one Chu Fenqu, during powdering, left side scraper is responsible for powdering to the right, and right scraper is responsible for powdering to the left.In addition,
SLM device working chamber side arranges that a powder supply cabin is used to supplement the powder in the areas Chu Fen.Different from unidirectional power spreading device, this confession
What powder device was taken is falling type powder supply.Another list doctor mode device passes through in inside one idler wheel of arrangement or ratchet
The direction of rotation of control idler wheel or ratchet achievees the purpose that two-way powder falling, or independent in equipment working chamber both sides arrangement two
Powder supply cabin, in the independent powder falling in both sides.
Either hilted broadsword pattern or double-pole pattern, are required for more complicated structure that could realize two-way powder laying.For
Hilted broadsword pattern or the idler wheel or ratchet that need two individual powder falling cabins or individual motor is needed to drive it internal turn
Dynamic, this makes equipment forming doors structure become increasingly complex, also proposes requirements at the higher level for the air-tightness of equipment；Meanwhile idler wheel
Or the driving of ratchet can introduce more mechanical driving devices again, and equipment manufacturing costs is caused to further increase.
For double-pole pattern, it is difficult to be adjusted to the problem of same level degree there are both sides scraper, this can cause to spread twice in succession
The effect of powder has differences, and can also exist on the forming of part influences；Moreover, double scraper powdering structures are often more in powdering execution
Primary clear powder can be just executed after secondary, thus all contain in the powder of the most of powderings of workbench it is certain it is laser sintered after
Bulky grain powder, therefore the powder being laid with is contaminated powders, this can not only influence the forming of part, but also scraper can be caused to scratch..
