Abstract

The invention discloses a selective laser melting single-tool bothway powder paving device which comprises a powder hopper, a feeding box, a scraper and a position sensor. The position sensor is in communication connection with a control system, starting and stopping of falling are controlled through the control system, and work is sensitive; a first rotating shaft and a second rotating shaft which are driven by a motor are arranged on the two sides of the feeding box, so that a stopping belt is driven to move, a falling opening is formed in the stopping belt and moves to a first feeding channel or a second feeding channel, powder falls to the left side or the right side of the scraper, meanwhile, a brush block is arranged on the inner wall of an installing hole, remaining powder on the stopping belt can be swept into the channels, and influences on movement of the stopping belt and work of the powder paving device are avoided. The powder paving device is sensitive in work and simple in structure, main structures are arranged outside the feeding box, checking is easy, and maintenance and replacement are facilitated.

Description

technical field [0001] The invention relates to the technical field of laser forming, in particular to a laser selective melting single-knife bidirectional powder spreading device and also relates to a laser selective melting equipment with the powder spreading device. Background technique [0002] Laser selective melting (SLM) is a method of direct forming of metal parts, and it is the latest development of rapid prototyping technology. This technology is based on the most basic idea of ​​rapid prototyping, that is, the "incremental" manufacturing method of layer-by-layer cladding. According to the three-dimensional CAD model, parts with specific geometric shapes are directly formed. During the forming process, the metal powder is completely melted to produce metallurgical bonding. Metal parts with complex shapes and structures that cannot be manufactured by traditional machining methods are one of the main directions for the application of laser rapid prototyping technolog...
