Abstract

The invention discloses a base shaft type metal 3D printer. The base shaft type metal 3D printer comprises a machine frame, a powder cylinder is arranged in the middle of the machine frame, the machine frame is connected with a base shaft driving device, long-strip-shaped limiting through holes are correspondingly formed in the opposite sides of the machine frame and the powder cylinder, and a base shaft comprises a base shaft body and base shaft connecting shafts at the two ends; the base shaft is located in the powder cylinder, and the base shaft connecting shafts at the two ends of the baseshaft penetrate through the long-strip-shaped limiting through holes to be detachably and fixedly connected with the base shaft driving device; and sealing assemblies used for preventing metal powderin the powder cylinder from overflowing are arranged between the base shaft connecting shafts and the long-strip-shaped limiting through holes. The basic shaft type metal 3D printer is simple in structure and convenient to use, complex components such as a powder laying device and a powder scraping device are omitted, the requirements for machining symmetry and the like of some rotating components are well met, the quality of printed and machined products is guaranteed, and the temperature stress of workpieces in the printing process is controlled.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a base shaft type metal 3D printer. Background technique [0002] Metal 3D printers have the advantages of personalized design, rapid molding, and short manufacturing cycle. They are very suitable for the manufacture of small batches, personalized metal parts with complex surfaces and internal structures. In the process of 3D printing metal powders, high energy density The laser directly acts on the metal powder, and the laser scans rapidly, so that the metal powder is rapidly melted and then rapidly condensed. [0003] For example, Chinese patent application number: CN201910146552.6, discloses a metal 3D printer that is convenient for timely cooling, including a top plate, a support rod, a bottom fixing seat, an upper fixing seat, a first motor, a first screw rod, and a first rotating sleeve , the second motor, the second screw rod and the third motor, the bottom ...
