Abstract

The invention discloses a mechanical shaft and a plasma rotation electrode powdering device and method, and relates to the field of metal powder preparation. The mechanical shaft and the device and method are used for solving the problems of difficulty in online adjustment of pressing force caused by a traditional spring pressing carbon brush device, non-uniform bar melting caused by poor high-speed rotation power supply and the like. According to the mechanical shaft, one end of a carbon brush penetrates through a hollow plunger to be electrically connected with the outside, the end face of the other end makes contact with a power supply shaft, and an insulating plate is bonded to the periphery of the end; a pipeline is connected with a servo power system and is used for exerting compressed air or hydraulic oil provided by the servo power system on the hollow plunger, so that the front end of the hollow plunger tightly presses the carbon brush; and the hollow plunger is of an annularhollow structure.

Description

technical field [0001] The invention relates to the technical field of metal powder preparation, and in particular to a mechanical shaft and plasma rotating electrode powder making device and method. Background technique [0002] Plasma rotating electrode process (English: plasma rotating electrode process, abbreviated as: PREP) technology is a metal powder preparation method based on the principle of high-speed rotary centrifugal atomization. The metal powder produced by this technology has high sphericity and good fluidity. , low impurity content, less satellite powder and other advantages, it has been widely used in powder metallurgy fields such as hot isostatic pressing (English: Hot Isostatic Pressing, abbreviated as: HIP), thermal spraying, porous catalytic packing, etc. due to its excellent performance. In recent years, with the development of national defense industry and aerospace technology, higher requirements have been placed on the quality and performance of ref...
