A 3D metal printer's forming cylinder take-out and return mechanism

Abstract

The invention relates to a forming cylinder take-out and reinstallation mechanism of a 3D metal printer, including a cylinder module, a piston module, a tray module, a positioning module, a lifting module, a drive module and a support frame; the tray module is used for reinstallation Coarse positioning of the cylinder module, or for receiving the cylinder module during separation; positioning module, used for precise positioning of the cylinder module during reassembly; lifting module, used for reassembling the cylinder module from the pallet module Lift up to position on the positioning module to realize the sealing of the molding cylinder and the molding chamber, or to lower the cylinder module from the positioning module to the tray module when taking it out, so as to realize the separation of the molding cylinder and the molding chamber; the drive module , installed on the support frame to achieve up and down movement, and detachably connected with the piston module. The invention can move the forming cylinder to the pick-up station outside the equipment to perform powder cleaning and pick-up work, and can quickly reassemble the forming cylinder, so that the secondary printing can be performed quickly.

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
