摘要： A machining method for three-dimensional open flow channel using high-speed arc discharge layered sweep, which arranges an axial line of an installation shaft of a tool electrode with six degrees of freedom to be perpendicular to an axial line of a to-be machined work piece in an arc discharge process, with the tool electrode sweeping in a closed path in a plane or a curved surface perpendicular to the installation shaft, wherein the path of the sweeping satisfies: a space of an enveloped space being formed by the tool electrode moving in the path and being coincident with a removed portion of the work piece does not exceed a preset machined cavity of the flow channel. The present invention is based on high-speed arc discharge of hydrodynamic arc breaking and realized layered milling and surface machining for three-dimensional open flow channels.

摘要： An electro-hydraulic combined device is provided. The electrical insulator is fixedly connected with a spindle shell; a top end of the electro-hydraulic joint supply base is fixedly connected with the electrical insulator; a connection port of the working fluid pipe and a binding post are arranged on the electro-hydraulic joint supply base; a bottom end of the electro-hydraulic joint supply base is provided with a terminal connection port; the connection port of the working fluid supplying pipe and the terminal connection port communicate with a fluid channel in the electro-hydraulic joint supply base; when the terminal connection port is snap-engaged with a top end of the terminal of electro-hydraulic joint supply pipes, the fluid channel in the electro-hydraulic joint supply base is communicated with a fluid channel in the terminal; the fluid channel in the terminal is further communicated with a flushing fluid container on an electrode shank for electro machining.

摘要： A metal additive manufacturing device is disclosed herein. The wire feeding mechanism in the protective bin can convey metal wires towards the substrate, the working medium filtration and circulation module conveys working mediums into the protective bin and discharges working mediums, the working medium between the metal wire and the substrate or between two metal wires is broken down, and plasma is generated and maintained; and under the action of high temperature of the plasma, the metal wires quickly melt to form the metal droplets. The rotating shaft drives the rotating arm to rotate. The working bin modules are disposed at both ends of the rotating arm. The droplets formed by the melting of the metal wires fly away from a melting area under the action of a centrifugal force, and the droplets reach the substrate or the surface of a machined workpiece, cool and solidify, and crystallize.
