Abstract

The invention discloses a powder cleaning equipment for laser selective melting parts, which comprises a powder cleaning box and a control mechanism arranged outside it. The powder cleaning box is a sealable cavity, which includes a rotating shaft, a turning platform and an ultrasonic vibration platform. The two ends of the rotating shaft are respectively fixed on the two opposite side walls of the box; The middle part can be flipped around the rotating shaft; the ultrasonic vibration platform is fixed on the flipping platform, and a first fixing unit is arranged on its upper surface; the control mechanism is connected with the rotating shaft and the ultrasonic vibration platform. It also includes a horizontal rotating platform, an air gun purging mechanism, a powder collecting mechanism, an inert gas protection mechanism and a dust cleaning mechanism. Through the cooperation of the above-mentioned various mechanisms and the control mechanism, the present invention can completely realize the all-round cleaning of the powder on the parts without dead ends, which not only saves labor, but also has zero pollution to the surrounding environment, which greatly protects the health of the operator, and has a wide range of applications. High cleaning efficiency.

Description

Technical field [0001] The invention relates to the technical field of laser selective melting and direct manufacturing, in particular to a powder cleaning equipment for laser selective melting of parts. Background technique [0002] Additive Manufacturing (AM) technology is a technology that uses the gradual accumulation of materials to manufacture solid parts. Compared with the traditional material removal-cutting technology, it is a "bottom-up" manufacturing method. In the past two decades, AM technology has achieved rapid development, such as "Rapid Prototyping", "3D Printing", and "Solid Free-form Fabrication". Law expresses the characteristics of this technology from different sides. [0003] Selective Laser Melting (SLM) direct manufacturing technology, also known as metal 3D printing technology, is the cutting-edge technology of additive manufacturing. Before processing, first use professional data processing software to slice and discretize the CAD model of the part and ...
