Method and apparatus for applying uniaxial compression stresses to a moving wire

摘要

An apparatus and method for moving a wire along its own axis against a high resistance to its motion causing a substantial uniaxial compression stress in the wire without allowing it to buckle. The apparatus consists of a wire gripping and moving drive wheel and guide rollers for transporting the moving wire away from the drive wheel. Wire is pressed into a peripheral groove in a relatively large diameter, rotating drive wheel by a set of small diameter rollers arranged along part of the periphery causing the wire to be gripped by the groove.

1. A method for applying uniaxial compression stresses to a solid moving wire comprising the steps of:
moving said wire along an arcuate path; applying axial force at multiple gripping locations along the surface of the wire as it is moved along said arcuate path; providing resistance to said wire moving along said arcuate path said resistance provided by a remotely located wire deformation processing device in combination with said axial force on said moving wire to cause high uniaxial compression stresses in said wire and; moving said uniaxially compressed wire without additional axial force applied to said wire whereby said wire is supported from buckling as it moves along a guided path to said remotely located wire deformation processing device.
