STRETCHING OF WIRE * ROD * PIPE AND LIKE BY STRETCHING NOZZLE USING MACRO SOUND

Document Type and Number:

Japanese Patent JPS53131264

Kind Code:

A

Abstract:

A method and apparatus are disclosed for the drawing of wire-like elements, such as, wires, rods, tubes, and the like. The method employs the use of macrosonics for deformation of the wire. The use of hydrodynamic lubrication together with the macrosonic drawing process substantially increases the permissible drawing speeds. Apparatus for performing the method includes a horn having a drawing die and a properly dimensioned channel for permitting hydrodynamic lubrication disposed therein.
