A powder feeding device for laser cladding machine

Abstract

The invention discloses a powder feeding device for a laser cladding machine, which comprises a casing, a pollination mechanism and a quantitative mechanism, the side of the casing is fixedly connected with a hose seat, and a Pneumatic conveyor. In the present invention, the powder material to be used is stored through the first material storage tank and the second material storage tank. During the powder feeding process through the first powder feeding chamber and the second powder feeding chamber, the movable plate is driven by the pneumatic expansion joint to The powder in the connection chamber is quantified. When the second powder feeding chamber is filled, the powder in the second powder feeding chamber can be conveyed through the pneumatic feeder, and then the powder to be used is passed through the hose The powder feeding function is achieved by ejecting from the nozzle. This device can convey different powder materials separately and has a good quantitative effect and high powder feeding efficiency; the powder ejected through the nozzle covers the objects to be clad, which can be used with The printing cladding process is suitable, and the powder spraying effect is good.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a powder feeding device for a laser cladding machine. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is a cutting-edge advanced technology involving physics, chemistry, materials science and engineering, computer science and technology, control science and engineering, mechanical engineering, biomedicine and engineering. Manufacturing Technology. Powder-feeding laser 3D printing technology is a new advanced manufacturing technology developed by combining rapid prototyping technology and synchronous feeding laser cladding technology. It uses high-energy laser beams to locally melt the metal surface to form a molten pool, and simultaneously Raw materials are sent into the molten pool synchronously to form a new metal layer that is metallurgically combined with the base metal and has a very low diluti...
