The invention discloses a spliced 3D printing powder cylinder with seal and explosion preventing functions. A bottom plate is included. A plurality of detaching cylinder bodies are arranged on the topof the bottom plate. A lead screw assembly penetrates through the middle portion of the bottom plate. The top end of the lead screw assembly extends into the detaching cylinder bodies and is connected with pistons located in the detaching cylinder bodies. Piston seal strips are arranged between the outer sides of the pistons and the inner walls of the detaching cylinder bodies. Piston cover plates are arranged on the tops of the pistons. A motor is fixedly arranged on one side of the bottom plate. An output shaft of the motor is sleeved with a driving wheel. The lead screw assembly is provided with a driven wheel matched with the driving wheel, and the driven wheel and the driving wheel are connected through a synchronous belt. The spliced 3D printing powder cylinder with seal and explosion preventing functions has the beneficial effects that compared with a traditional integral cylinder structure, the explosion preventing performance of the spliced 3D printing powder cylinder is effectively improved while the inner wall machining precision and seal performance are guaranteed.
Description
technical field [0001] The invention relates to the technical field of 3D printing powder cylinders, in particular to a spliced 3D printing powder cylinder with sealing and explosion-proof functions. Background technique [0002] 3D printing is a common name for additive manufacturing technology. It is a technology that uses data to accumulate material layer by layer to manufacture solid parts. Compared with traditional material removal technology, 3D printing technology can form parts with complex shapes, with high forming accuracy and material saving. . [0003] Among them, laser selective melting is one of the representative technologies of powder bed metal 3D printing, which is an advanced laser additive manufacturing technology developed based on the basic principle of SLS rapid prototyping technology. The three-dimensional digital model of the part is sliced and layered by special software, and after obtaining the profile data of each section, the high-energy lase...
