Precise proportioning powder feeding system and powder outlet amount and proportioning amount dynamic control method

Abstract

The invention relates to a precise proportioning powder feeding system and a powder outlet amount and proportioning amount dynamic control and detection method, and belongs to the field of synchronouspowder feeders in additive manufacturing and laser manufacturing. The system consists of a control computer, a control cabinet, powder feeders, powder amount detecting modules, powder amount controlmodules and a precise proportioning control module, wherein the powder feeders store and hold powder and convey the powder to a laser machining area; the powder amount detecting modules acquire precise powder amount output by the powder feeders in real time, and transmit powder amount data to the precise proportioning control module; and the powder amount control modules control the powder amountoutput by the powder feeders in real time, receive control information of the precise proportioning control module, and regulate the power outlet amount in real time. The precise proportioning controlmodule controls the powder feeding amount and the powder feeding proportioning amount dynamically in real time to achieve precise proportioning control. The precise proportioning powder feeding system and the powder outlet amount and proportioning amount dynamic control and detection method support mixed powder feeding of a plurality of materials, ensure precise proportioning control of various materials, and effectively improve the powder feeding precision, the continuity, the stability and the controllability.

Description

technical field [0001] The invention relates to the technical field of synchronous powder feeders. In particular, it relates to a powder feeding system for precise ratio control of various powders in laser cladding. Background technique [0002] The powder feeder is one of the core components in laser cladding processing equipment and 3D printing equipment. It delivers the set powder to the area to be processed according to the processing technology. The performance of the powder feeder directly affects the quality of the processed parts. Even a very small powder feeding deviation will cause major changes in the geometry, thickness, and surface smoothness of the parts. Therefore, in high-precision processing, the powder feeding system design is particularly important. Especially with the increasing application of gradient functional materials research and development, microstructure functional product manufacturing, precision repair, etc., a diversified powder feeding syst...
