Problems solved by technology

The existing inflation and exhaust methods usually first extract the gas in the forming cavity, and then pass in the inert gas. The entire inflation and exhaust time is very long, which makes it more difficult to maintain a low-oxygen atmosphere in the forming cavity, which seriously affects The production process is interrupted, resulting in low production efficiency, high cost, and unnecessary waste of resources

Abstract

The invention provides an air inflation and exhaust system. The system comprises a sealing device which forms a forming cavity and a flexible device used for keeping and releasing the gas, wherein thesealing device is provided with a gas outlet, a gas inlet, a first through hole and a second through hole, the gas outlet is used for allowing the gas in the forming cavity to be discharged out of the cavity, the gas inlet is used for enabling the inert gas to enter the forming cavity through the gas inlet, the first through hole is used for allowing a part of a access device to be accommodatedin the forming cavity of the sealing device in a sealing mode, and the main body part of the flexible device is arranged in the forming cavity of the sealing device in a sealing mode through the second through hole; and the flexible device is provided with a gas inflation port and a gas extraction port which are used for allowing the gas to be fed and allowing the gas to be extracted respectively,and the gas inflation port and the gas extraction port are positioned outside the sealing device. The invention further provides additive manufacturing equipment and an air inflation and exhaust method.

Description

technical field [0001] The invention belongs to the technical field of laser additive manufacturing equipment, and in particular relates to an inflation and exhaust system, an additive manufacturing equipment including the inflation and exhaust system, and an inflation and exhaust method. Background technique [0002] Additive manufacturing technology, also known as 3D printing, according to the definition of the American Society for Experimental Materials (ASTM): Additive manufacturing (3D Printing) is designed with the help of three-dimensional digital models, through software layered discrete and numerical control molding systems, using laser beams, Metal powder, ceramic powder, plastic, cell tissue and other special materials are stacked and bonded layer by layer by electron beam and other methods, and finally superimposed and formed to produce a physical product. Laser melting deposition technology, as a kind of additive manufacturing technology, compared with tradition...
