Abstract

The invention discloses a printing device of SLM equipment. The printing device comprises a base plate, a workbench and a printing circular truncated cone. Supporting columns are fixedly connected tothe four corners of the upper surface of the base plate, the workbench is fixedly connected to the upper surfaces of the supporting columns, a circular through hole is formed in the middle of the upper surface of the workbench, a material leaking hole is formed in the upper surface of the workbench and located at the right side of the circular through hole, and a material collecting box is fixedlyconnected to the right side of the upper surface of the base plate; the material leaking hole is communicated with a material collecting box through a material guiding hopper, and a hydraulic cylinder is fixedly connected to the middle of the upper surface of the base plate; and a powder scraping device comprises a mounting frame and a powder scraping knife, multiple sets of corresponding slidinggrooves are formed in the left side and the right side of the mounting frame in the horizontal direction, and adjusting plates are arranged in the sliding grooves in a sliding manner. According to the printing device of the SLM equipment, the problems that in the prior art, when a rotating part is machined, axial symmetry is difficult to meet, and workers need to clean redundant powder are solved; and the uniformity of powder scraping is improved in a multi-time powder scraping manner, and meanwhile accurate adjustment of the thickness of a powder layer can be achieved.

Description

technical field [0001] The invention relates to the technical field of SLM equipment, in particular to a printing device of the SLM equipment. Background technique [0002] Selective laser melting (SLM) metal 3D printing technology (Selective laser melting, SLM) uses a precise focus spot to quickly melt the pre-laid layers of metal powder, and can almost directly obtain functional parts with arbitrary shapes and complete metallurgical bonding. The density can reach nearly 100%. It is a rapid prototyping technology with great development prospects, especially in aerospace, medical, automobile, mold and other fields, which has extremely important application prospects. There is a powder spreading process in the SLM process, that is, after the powder is sent to the powder bed by the powder feeding mechanism, it is paved by the powder spreading device. This process directly affects the printing result. [0003] 3D printing is a kind of rapid prototyping technology, also known a...
