METHOD FOR MAKING TOOL FOR FORMING Russian patent published in 2005 - IPC

FIELD: plastic working of materials, preferably metals, possibly in machine engineering for making tools for forming processes.

SUBSTANCE: method comprises steps of preliminarily making of easy-to-work material model of one member of tool in scale 1:1; making concrete form for producing reinforced concrete at using said model as bottom of form; applying layer of liquid material containing filler onto model; placing reinforcement in concrete form; then filling form with concrete; after curing of concrete, removing form and applying liquid material onto working surface of formed member of tool; using formed first member of tool and additional concrete form for making second member of tool from concrete kind no less than 500 and using as filler quartz sand, basalts or gneisses.

EFFECT: simplified low-cost process of manufacturing forming tool.
