Description

Powder collecting tank for metal 3D printer

Technical Field

The utility model belongs to the technical field of 3D prints, specifically relate to a powder collection tank for metal 3D printer.

Background

With the development of technologies, 3D printing technologies are increasingly used. When metal 3D printing is carried out, metal powder needs to be uniformly tiled and then selectively melted by laser.

In the powder paving process, in order to ensure the uniformity and reliability of the powder paving, the amount of the supplied powder is greater than the actual required amount when the powder is paved every time, and the powder of the redundant part can be pushed to the recovery tank by the powder paving scraper to fall and be recovered.

In addition, when metal selective laser melting is performed, it is necessary to fill inert gas into the apparatus and discharge oxygen from the apparatus.

Most of the existing collecting tanks are directly made of metal, the material level of powder collection in the bottle cannot be conveniently observed, in addition, the inner cavity of the collecting tank becomes a dead zone of equipment, oxygen in the collecting tank cannot be smoothly discharged, and the printing quality is easily influenced.

Disclosure of Invention

The utility model provides a metal 3D is powder collection tank for printer ensures that the metal 3D printer can be smooth when carrying out the washing gas operation will collect the interior oxygen outgoing of jar, the collection condition of metal powder in the observation collection jar that simultaneously can be convenient.

In order to realize the technical purpose, the utility model discloses a technical scheme is: a powder collecting tank for a metal 3D printer comprises a collecting tank body, wherein the collecting tank body is composed of a square tank body, a feeding hole and a handle, the feeding hole is formed in the top of the square tank body, the handle is arranged on one side face of the tank body, the handle is hollow and communicated with the bottom of the tank body, an air inlet with an upward opening is formed in the upper portion of the handle, a long-strip-shaped observation opening is formed in the other side face of the tank body in the height direction, a pressing plate presses glass and a sealing gasket to seal the observation opening, and the sealing gasket is arranged between the observation opening and the glass.

The utility model has the advantages that: the utility model provides a metal 3D is powder collection tank for printer enables the smooth oxygen outgoing with the collection tank of metal 3D printer when carrying out the scrubbing operation when using, the collection condition of metal powder in the observation collection tank that simultaneously can be convenient.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the powder collection tank for the metal 3D printer comprises a collection tank 1, wherein the collection tank 1 is composed of a tank body 1a, a feed port 1b and a handle 1c, the tank body 1a is a square tank body, the top of the tank body is provided with the feed port 1b, the handle 1c is arranged on one side surface of the tank body 1a, the handle 1c is hollow and communicated with the bottom of the tank body 1a, the upper part of the handle 1c is provided with an air inlet 1D with an upward opening, the other side surface of the tank body 1a is provided with a long strip-shaped observation port 1e along the height direction, a pressure plate 4 presses a glass 3 and a sealing gasket 2 to seal the observation port 1e, and the sealing gasket 2 is arranged between the observation port 1e and the glass.

When the device is used, the feeding port 1b is connected with a discharging port (not shown in the attached drawing) of the metal 3D printer, the air inlet 1D is connected with an inert gas pipe (not shown in the attached drawing), and when the metal 3D printer is used for gas washing operation, inert gas enters the collecting tank 1 from the air inlet 1D to wash the air in the collecting tank and is discharged upwards; when metal powder is collected, the powder falls into the collection tank 1 through the feed port 1b, and the internal powder collection condition is observed through the glass 3.
