Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0026] The laser selective melting two-way powder spreading device of the present invention includes a scraper mounting frame 1 , a scraper leveling frame 2 , a first scraper 4 and a second scraper 5 .

[0027] The scraper leveling frame 2 is used for scraper leveling, such as figure 1 As shown, it includes a front wall 21 , a rear wall 22 and two left and right side walls 23 , and the middle cavity part formed by the four walls is used to accommodate the scraper mounting frame 1 . There are two mounting bosses 24 extending outwards from the upper edges of the front wall 21 and the rear wall 22 respectively. Screw holes for fixing the scraper leveling frame 2 and screw holes 25 for leveling are distributed on the mounting bosses 24 . Screw holes for fixing the scraper mou...

Abstract

The invention discloses a two-way powder spreading device for laser selective melting, comprising a scraper mounting frame, a scraper leveling frame, a first scraper and a second scraper; the scraper mounting frame is detachably and fixedly sleeved in the scraper leveling frame, and The leveling frame is kept parallel in the horizontal direction; the scraper leveling frame has a leveling mechanism for leveling. The installation of the scraper and the second scraper; the first scraper and the second scraper are installed on both sides of the lower part of the scraper mounting frame in such a way that the upper surface is close to the horizontal installation surface and the inner surface is close to the vertical installation surface. Also disclosed is a laser selective melting device with the above-mentioned powder spreading device. The powder spreading device of the present invention can ensure the leveling accuracy, and it only needs to be leveled when the equipment is installed for the first time, and it does not need to be leveled again when the scraper is replaced later, which is simple and easy.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing equipment, and in particular relates to a two-way powder spreading device for laser selective melting, and also relates to laser selective melting equipment with the two-way 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 rapi...
