DEVICE FOR PREPARATION AND FEED OF PASTE IN TUBULAR ELECTRODE-TOOL

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to device intended for mixing fine metal powders with fluids to paste state and feeding paste into tubular electrode-tool to be used in electric erosion hardening. Proposed device comprises container with loose material carrier made up of encased auger, fluid feed branch pipe and paste discharge appliance. Elastic envelope is secured at auger case end. Auger tip is brought inside elastic shell to interact therewith. Paste discharge appliance is made up of curved tube with one end arranged with clearance above container bottom while opposite end is brought out of container and jointed to tubular electrode-tool. ^ EFFECT: higher quality of mixing fine metal powders with surfactant fluids. ^ 3 cl, 1 dwg
