The invention discloses a powder removing device, and belongs to the technical field of rapid forming and manufacturing. The powder removing device comprises a box body, a vibration table, an air inlet mechanism and an air exhaust mechanism, and an air inlet channel and an air outlet channel are formed in the box body; the vibration table is arranged in the box body, and a part to be subjected to powder removal is placed on the vibration table; the air inlet mechanism is arranged at the air inlet channel and used for conveying airflow into the box body so as to drive powder to move in the box body; and the exhaust mechanism is arranged at the air outlet channel and is used for exhausting gas containing powder in the box body. According to the powder removing device provided by the invention, the vibration table is arranged in the box body, and the part to be subjected to powder removal is arranged on the vibration table, so that powder can be thoroughly separated from the part to be subjected to powder removal through vibration; meanwhile, the air inlet channel and the air outlet channel are arranged on the box body, so that circulation of air between the outside of the box body and the inside of the box body is realized; and the air inlet mechanism and the air exhaust mechanism are arranged to exhaust gas containing powder in the box body, so that the powder removal efficiency is finally improved.
Description
technical field [0001] The invention relates to the technical field of rapid prototyping and manufacturing, in particular to a powder removing device. Background technique [0002] Compared with traditional manufacturing methods, additive manufacturing technology can obtain more precise and complex parts faster, which makes additive manufacturing technology popular. However, the cavities, supporting structures and reinforcing ribs of parts produced by additive manufacturing technology will be covered with a layer of powder. These powders are assembled with the parts and are prone to dust explosions in a closed environment. [0003] In the prior art, a high-pressure air gun is used to blow air on the surface of the parts to make the powder escape, but on the one hand, it not only pollutes the environment, but also makes it easy for workers to inhale the powder, causing damage to the human body; on the other hand, the high-pressure air gun can only blow away the powder. Powde...
