Problems solved by technology

This method is at a position far away from the suction port of the suction dust removal device. The smoke and splashes generated cannot be sucked away, and they still fall on the processing and forming area. If the wind speed is increased to blow away the smoke and splashes, it will Blow away the raw metal powder, affecting the additive work

Embodiment 1

[0028] Example 1: Please refer to figure 1 , image 3 and Figure 4 , this embodiment discloses a dust removal structure in a sealed cabin for additive manufacturing, which includes a hollow box body 2 and a moving support 7. The front side of the box body 2 is provided with an operation opening that communicates with the inside and outside of the box body. An opening and closing box door 8 is installed on the operation opening, a processing and forming platform 11 is provided on the bottom side of the inner cavity of the box body 2, and an air intake cover is installed in the inner cavity of the box body 2 through the moving support member 7 10. The horizontal position of the air intake cover 10 is adjustable. The air intake cover is provided with a suction port connecting the inside and outside of the air intake cover. The upper side of the box body 2 is provided with a mounting hole, and a laser generator is installed in the mounting hole. device 4, and the box body 2 is ...

Embodiment 2

[0038] Embodiment two: if figure 1 As shown, this embodiment discloses a dust-removing structure in a sealed cabin for additive manufacturing. A second linear motor 73 installed in parallel on the inner wall of the box body 2, a first linear motor 71 is installed between the movers of the two second linear motors 73, and the mover of the first linear motor 71 It is fixedly connected with the upper end of the vertical rod 72 , and the lower end of the vertical rod 72 is fixedly connected with the outer side of the air intake cover 10 .

[0039] The controller of the additive manufacturing machine controls the first linear motor 71 and the second linear motor 73 to work; the first linear motor 71 and the second linear motor 73 drive the intake cover 10 to move horizontally through the vertical rod 72, so that the intake cover 10 Real-time tracking close to the heat source action area and close enough.

Embodiment 3

[0040] Embodiment three: as image 3 As shown, this embodiment discloses a dust-removing structure in a sealed cabin for additive manufacturing. There are less than three electric telescopic rods 74, the upper end of the electric telescopic rod 74 is rotatably connected to the upper side of the inner cavity of the box body 2, and the lower end of the upper end of the electric telescopic rod 74 is connected to the outer side of the air intake cover 10 Rotational connection; the controller of the additive manufacturing machine separately controls the electric telescopic rods 74 to work together, so that the air intake cover 10 can track and approach the heat source action area in real time and is close enough, and the electric telescopic rods 74 work together to control the air intake cover 10 to move on a horizontal plane. Common means in the prior art, and the height adjustment of the air intake cover 10 is convenient.

Abstract

The invention discloses a dust removal structure in a sealed cabin for additive manufacturing. The dust removal structure comprises a box body with the hollow interior and a movable supporting piece,an operation opening communicating with the interior and the exterior of the box body is formed in the front side of the box body, a box door capable of being opened and closed is installed on the operation opening, and a machining forming platform is arranged on the bottom side of an inner cavity of the box body; an air inlet cover is installed in an inner cavity of the box body through the movable supporting piece, an air suction port communicating with the interior and the exterior of the air inlet cover is formed in the air inlet cover, an installation hole is formed in the upper side of the box body, a laser generator is installed in the installation hole, and an air purification box and a draught fan are installed on the upper side of the box body; and a through hole for communicating the interior and the exterior of the air inlet cover is formed in the air inlet cover. According to the dust removal structure in the sealed cabin for additive manufacturing, a dust suction device can track and approach a heat source action area in real time and is close enough to the heat source action area, smoke dust particles generated in the additive machining process are sucked away in time through the proper air pressure difference generated by the draught fan, and meanwhile raw material metal powder is not affected.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing machines, in particular to a dust removal structure in a sealed cabin for additive manufacturing. Background technique [0002] During the operation of the additive manufacturing machine, high-energy rays generated by laser or high-energy electronics and other equipment irradiate the processing and forming area (the processing and forming area contains raw metal powder) to form a small area of ​​heat source action area, which will produce metal oxidation. These substances spread in the form of smoke or splashes. If they fall on the processing and forming area, they will cause metal powder pollution, affect the mechanical properties and appearance of the additive manufacturing forming, and even cause the work task to fail midway. [0003] The existing dust removal method is to fix the suction dust removal device at a specific position near the processing and forming area, and the air...
