The invention discloses a
powder spreading device for rapid forming equipment. The device mainly comprises a quantitative
powder conveying device, a movable
silo, a movable arm, a movable frame and the like. The quantitative
powder conveying device is used for supplying powder to the movable
silo. Whether the powder falls down or not is controlled through a rotating sheet. According to the section of parts, the movable
silo does regular
translational motion within a working plane under the drive of the movable arm and the movable frame, and a scraper on the silo can realize dynamic powder spreading. By combining the movable arm and the movable silo with the movable frame, defining the powder within the area of the parts and adjusting the magnitude and the position of spread powder according to the change of the section of the parts, not only can the amount of the used powder is greatly saved, but also the powder spreading speed is high; and the structural design of the powder spreading device is simple, the powder spreading device is convenient to disassemble and assemble, the realization is easy, the cost is lower and the powder spreading device has an important application value to the improvement of the overall technical level of a
powder bed quick forming technology.
