Abstract

The invention discloses a powder feeder capable of drying and preheating the powder based on the laser additive manufacturing and the powder feeding method. The powder feeder comprises an electrical element, a hopper and a ceramic heating tank, wherein the ceramic heating tank is used for drying and heating the powder; and the electrical element located at the lower part of the powder feeder comprises a control system (11) and a motor (13), and the control system (11) is connected to the motor (13). According to the powder feeder and the powder feeding method, the structure is simple, the timefor independently drying and preheating the powder is saved, and real-time preheating is realized. The quality of the powder fed into a melting tank is better, so that the good quality of a forming part is ensured.

Description

technical field [0001] The invention designs a powder feeding device for laser additive manufacturing, and in particular relates to a powder feeding device that can dry and preheat powder based on laser additive manufacturing. Background technique [0002] With the rapid development of laser additive manufacturing technology and its wide application in industrial fields such as aviation, automobile and metallurgy, the performance requirements for laser additive manufacturing equipment are also getting higher and higher. The powder feeding device of laser additive manufacturing is one of the main factors affecting the performance of laser additive manufacturing equipment. The commonly used powder feeder device is generally composed of electrical components below the powder feeder and a hopper above it. [0003] The existing powder feeding device can no longer meet the needs of laser additive manufacturing molded parts. Moisture in the powder can lead to problems such as pow...
