Taking-out and reassembling mechanism of forming cylinder block of 3D metal printer

Abstract

The invention relates to a taking-out and reassembling mechanism of a forming cylinder block of a 3D metal printer. The taking-out and reassembling mechanism comprises a cylinder block module, a piston module, a tray module, a positioning module, a lifting module, a driving module and a supporting frame, wherein the tray module is used for conducting coarse positioning on the cylinder block module during reassembling or carrying the cylinder block module during separation; the positioning module is used for accurately positioning the cylinder block module during reassembling; the lifting module is used for lifting the cylinder block module from the tray module to the positioning module to be positioned during reassembling in order to realize sealing of the forming cylinder block and a forming chamber, or is used for descending the cylinder block module from the positioning module to the tray module during taking out in order to realize separation of the forming cylinder block and the forming chamber; and the driving module is arranged on the supporting frame to move up and down, and is detachably connected to the piston module. According to the taking-out and reassembling mechanism, a forming cylinder can be moved to a taking station outside the equipment for powder cleaning and taking work, and the forming cylinder block can be quickly reassembled, so that secondary printing work can be quickly conducted.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a forming cylinder take-out and reinstallation mechanism of a 3D metal printer. Background technique [0002] Additive manufacturing technology is based on 3D CAD model data. By adding materials to layer-by-layer manufacturing, it is based on computer 3D design models, and uses high-energy beams to accumulate materials layer by layer through software layered discrete and numerical control forming systems. Finally, superposition and forming are made to create a physical product. [0003] Laser selective melting (SLM) is a method of direct forming of metal parts and is the latest development of additive manufacturing technology. This technology is based on the most basic idea of ​​rapid prototyping, that is, the "incremental" manufacturing method of layer-by-layer cladding, and directly forms parts with specific geometric shapes according to the three-di...

Problems solved by technology

However, due to the large amount of powder in the parts formed by 3D metal printing, if the powder is cleaned in the molding room, it will pollute the optical protection lens. At the same time, because the parts are printed on the substrate, it is inconvenient to disassemble the substrate, and the parts are too heavy. Therefore, It is necessary to develop a mechanism that can take out the forming cylinder together with the piston to the pick-up station outside the equipment to realize the work of cleaning the powder and reassembling the forming cylinder at the same time
