Description
Technical field
The invention belongs to selective laser fusing SLM device technical field, it is related to a kind of 3D printing for heavy parts and sets
It is standby.
Background technology
Selective laser fusing SLM is a kind of method of metalwork direct forming, is the latest development of RP technique.Should
Most basic thought of the technology based on Quick-forming, i.e., " increment " manufacture successively melted, according to three-dimensional CAD model directly into
Shape has metal dust in the part of geometry in particular, forming process to be completely melt, produces metallurgical binding.Use this technology can be with
The metal parts for the shape and structure complexity that the traditional machining means of shaping can not be manufactured, selective laser fusing SLM technologies
It is one of Main way of Laser Rapid Prototyping Technique application.
The equipment of existing SLM 3D printings is divided to two kinds, and a kind of is the equipment without independent pickup cabin, it is another be containing
The equipment in independent pickup cabin, both the above existing scheme has the following disadvantages：
(1) for the equipment in not independent pickup cabin, as shown in figure 4, mainly including Optical devices 1, formation cylinder 2, powdering
Device 3, powder feeder unit 4 and receipts powder device 5, shaping cabin 6, during its work, wherein, opticator 1 is uniformly fixed on shaping cabin 6
, there is a certain distance at top apart from laser sintered face.And parameter of this distance inside Optical devices is determined, usually exist
Within 800mm, so determine that the internal height in shaping cabin 6 can not be too high, when the workpiece height printed is smaller, workpiece
It lifting can enter to shape in cabin completely, and then it is taken out from shaping cabin 6.But it is too high to work as printed workpiece, higher than shaping
The inside maximum space height in cabin, workpiece can not lifting completely, complete lifting workpiece can directly impinge the light at the top of formation zone
Device is learned, is caused danger.Because the workpiece of printing is excessive, printing can not take out workpiece after terminating from shaping cabin.
(2) equipment for the addition of independent pickup cabin, as shown in figure 5, another independent pickup cabin 8 is used to take
One openable hatchcover 9 is arranged at part, the top of pickup cabin 8, during printing, formation cylinder part 2 and the shaping consistency from top to bottom of cabin 6, pickup
When, pickup cabin or formation cylinder are moved, formation cylinder portion is alignd with pickup cabin, pickup cabin hatchcover is opened, in the mistake of cleaning part
It can stretch, clear up, workpiece can be hung at the hatchcover of pickup cabin at the hatchcover of pickup cabin at the top of Cheng Zhong, lifting workpiece, workpiece
Go out.No longer there is the danger that workpiece bumps against opticator, while also allow the higher workpiece of equipment print over, but this scheme
Shortcoming be that addition pickup cabin adds equipment and raised the price and cost.
The content of the invention
It is an object of the invention to provide a kind of 3D printing equipment for heavy parts, solve present in prior art
The problem of being caused danger because of the too high easy shock formation zone top optical device of workpiece.
The technical solution adopted in the present invention is, for the 3D printing equipment of heavy parts, including shaping cabin, shaping cabin top
Portion, which offers to be fixed with notch both sides on two line slideways, line slideway at the top of notch, shaping cabin, is embedded with sliding block, sliding block
On be fixed with Optical devices, shaping cabin lower surface, which is fixedly installed in formation cylinder, formation cylinder, is provided with hoistable platform, in shaping cabin
Powder feeder unit is installed with the wall of side.
The features of the present invention is also resided in,
Shaping is also equipped with power spreading device in cabin.
Shaping cabin lower surface is also equipped with receiving powder device.
The direction that notch is just stretching out to workpiece, and the size of notch is more than the maximum cross-section for printing workpiece.
Optical devices are slided along line slideway, and two extreme positions of Optical devices movement are respectively that Optical devices are complete
Notch, Optical devices is covered completely to stagger notch.
The beneficial effects of the invention are as follows a kind of 3D printing equipment for heavy parts of the invention：
(1) it is due to that the Optical devices shaped at the top of cabin can be by straight line although shaping cabin internal height does not become
Behind guide rail is moved to, the top notch shaped at the top of cabin can be staggered completely, so that workpiece can stretch out from top notch
Shape cabin.So the present invention can be to cause equipment can be with the higher workpiece of print over, during cleaning or pickup, lifting
Workpiece, workpiece will not bump to engineering system, it is to avoid dangerous generation.
(2) during the higher workpiece of print over, it is not necessary to extra one independent pickup cabin of increase, equipment can fully be reduced
Volume and manufacturing cost.

Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
The 3D printing equipment for heavy parts of the present invention, as shown in figure 1, including shaping cabin 6, the top of shaping cabin 6 is opened
Provided with notch 12, the top of shaping cabin 6, which is fixed with the both sides of notch 12 on two line slideways 11, line slideway 11, is embedded with sliding block
13, Optical devices 1 are fixed with sliding block 13, the shaping lower surface of cabin 6, which is fixedly installed in formation cylinder 2, formation cylinder 2, is provided with lifting
Powder feeder unit 4 is installed with platform 10, the shaping madial wall of cabin 6.
Shaping is also equipped with power spreading device 3 in cabin 6.
The shaping lower surface of cabin 6 is also equipped with receiving powder device 5.
The direction that notch 12 is just stretching out to workpiece 7, and the size of notch 12 is more than the maximum cross-section for printing workpiece 7.
Optical devices 1 are slided along line slideway 11, and two extreme positions that Optical devices 1 are moved are respectively Optical devices
1 covers notch 12, Optical devices 1 completely staggers notch 12 completely.
The present invention is for the operation principle of 3D printing equipment of heavy parts：By Optical devices 1 in line slideway 11
It is upper movable, when Optical devices 1 are moved to above, that is, it is exactly that Optical devices 1 cover top notch 12 completely, such as Fig. 2 institutes
Show, now, Optical devices are print job status directly over print area, its printing type and beating shown in existing Fig. 4
Printing apparatus is identical, printed to be referred to as：Metal dust on laser projection to print platform is formed Optical devices.
After workpiece printing terminates, as shown in figure 3, behind Optical devices 1 are moved to by line slideway 11, with top slot
Mouth 12 staggers completely, it is necessary to by hoistable platform by the continuous lifting of workpiece until work during workpiece is cleared up and is taken out
Part carries away formation cylinder part completely, when workpiece is lifted to certain altitude, and workpiece can just be stretched out by top notch and be shaped
Cabin, while Optical devices will not be encountered.
After workpiece is cleared up or pickup terminates, before Optical devices 1 can be again moved back to by line slideway 11, due to straight line
Guide precision is higher, the state so Optical devices 1 can resume work immediately.
