Abstract

The invention discloses an inert atmosphere control device for laser forming and repair. A return air duct (13) is sequentially connected in series with a three-way valve (2) of an exhaust pipe, a dust filter (3), a diaphragm booster pump (4), a pressure gasholder (5), a three-way valve (7) of an air inlet pipe, a dehydrator (8), an argon purifier (9) and a water cooling jacket (10); an air intake pipeline (11) of the water cooling jacket is connected with a water cooling unit (10) and an atmosphere protective cover (1); an exhaust air duct (14) is connected with the three-way valve (2) of the exhaust pipe; both ends of an air intake duct (15) of the air storage tank are respectively connected with the three-way valve (7) of the air inlet pipe and the air intake pipeline (11) in a sealing way; and both ends of an air supplement pipeline (16) are respectively connected with a gas bottle (6) and the pressure gasholder (5). The invention causes work air in a laser forming and repairing process to be cyclically utilized, reduces use and exhaust of argon, saves the running cost, controls contents of oxygen and nitrogen up to 10 ppm in a working process, and ensures the quality of the laser forming and repair.

Description

1. Technical field [0001] The material processing field of the present invention is specifically an inert atmosphere control device for laser forming and repairing. 2. Background technology [0002] The metal raw materials used in laser three-dimensional forming technology and laser forming and repairing technology are mostly powder materials. The process of forming and repairing is: the laser molten pool moving according to the predetermined trajectory receives the fed powder, the powder is melted at high temperature, and the laser beam moves After opening, the original molten pool solidifies and continues to form a new molten pool, which is a process of point deposition and point formation. In the process of laser three-dimensional forming and repairing, it is the key to ensure the quality of forming and repairing to prevent the contamination of molten pool and avoid alloy oxidation. Therefore, laser three-dimensional forming and repair equipment need to be equipped with ...
