Abstract
Metal 3D printing process needs to use glove box to be operated, but how to ensure that it is to ensure the key that can metal parts smoothly shape that pressure equilibrium inside and outside glove box is maintained during glove box use, the rupture of gloves can be otherwise caused, the printing-forming process of metal parts is influenceed.Thus, the device for maintaining pressure equilibrium inside and outside metal 3D printing process glove box is one of core apparatus of metal 3D printing process.The invention provides the device that pressure equilibrium inside and outside glove box is maintained during a kind of metal 3D printing, including the vacuum tank that is shaped for metal parts and the glove box equipped with gloves, also including the following device inside glove box：Two check valves of connection glove box and vacuum tank；For starting two the two of check valve metal strip cylinders.The device is able to maintain that during metal 3D printing pressure equilibrium inside and outside glove box such that it is able to use glove box normal safe.
Description
Technical field
The present invention relates to a kind of device, and in particular to one kind is for maintaining during metal 3D printing pressure inside and outside glove box
The device of balance.
Background technology
Metal 3D printing process needs to use glove box to be operated, but how to ensure to be tieed up during glove box use
It is to ensure the key that can metal parts smoothly shape to hold pressure equilibrium inside and outside glove box, can otherwise cause the rupture of gloves, shadow
Ring the printing-forming process of metal parts.Thus, the device of pressure equilibrium is inside and outside maintenance metal 3D printing process glove box
One of core apparatus of metal 3D printing process.
The content of the invention
For the pressure equilibrium maintained required for glove box during metal 3D printing and vacuum tank, the purpose of the present invention is
A kind of device for maintaining pressure equilibrium inside and outside glove box during metal 3D printing is provided, to solve the skill of metal 3D printing
Art problem.
According to a kind of device for maintaining pressure equilibrium inside and outside glove box during metal 3D printing that the present invention is provided,
Glove box including the vacuum tank shaped for metal parts and equipped with gloves, check valve, sealing inside glove box
Circle and metal strip cylinder；The check valve is used to connect glove box and vacuum tank；
The sealing ring is used for seal box；The metal strip cylinder is used to start two check valves.
Further, the number of the check valve is 2.
Further, it is provided with gloves groove in the glove box.
Further, the number of the hand gloves groove is 2.
Further, spring and small ball are provided with the check valve, small ball is withstood on metal strip cylinder by the spring
On.
The present invention has the advantages that：
This is used to maintain the device combination metal 3D printing selective laser of pressure equilibrium inside and outside glove box during metal 3D printing
Smelting technology, is able to maintain that during metal 3D printing pressure equilibrium inside and outside glove box such that it is able to use hand normal safe
Casing.
Brief description of the drawings
By reading reference picture 1, Fig. 2, Fig. 3, features, objects and advantages of the invention will become more apparent upon：
Vacuum tank and glove box interior view that Fig. 1 is provided for the present invention；
Vacuum tank and glove box junction check valve local structural graph that Fig. 2 is provided for the present invention；
The one-way valve structures figure that Fig. 3 is provided for the present invention.
Specific embodiment
Below in conjunction with Fig. 1 ~ 3, the present invention is described in detail, the invention discloses one kind for maintaining metal 3D to beat
During print inside and outside glove box pressure equilibrium device, it is disclosed by the invention for maintaining during metal 3D printing in glove box
The device of outer pressure equilibrium includes：For metal parts shaping vacuum tank, the glove box equipped with gloves, connection glove box with it is true
Two check valves 1 of empty van, the sealing ring for seal box, for starting two the two of check valve 1 metal strips circles
Post 4.The present invention realizes the function that pressure equilibrium inside and outside glove box is maintained during metal 3D printing in set of device, so that
Enabling to metal 3D printing process can smoothly complete.
During metal 3D printing, after glove box closing, the metal cylinder in Fig. 3 can push up open small ball 3, this
Sample can just realize the connection of vacuum tank and glove box to reach the balance of pressure inside and outside glove box by gas connection mouth.Work as hand
After casing is opened, metal cylinder extracts check valve 1, and spring 2 will rebound, and such glove box will separate with vacuum tank, from
And can normally use glove box.
Specific embodiment of the invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can within the scope of the claims make various deformations or amendments, this not shadow
Sound substance of the invention.
