Method and apparatus for straightening of elongated workpieces |
摘要 |
A method of straightening elongated workpieces of circular or other cross section comprises subjecting a portion of the workpiece during its movement in longitudinal direction thereof to rotary bending forces so that successive curvatures of the workpiece in a zone trailing said portion in said direction gradually increase to thereby surpass the yield point of the material of the workpiece and in a zone leading said portion in said direction gradually decrease in such a manner that the decrease of the curvatures and the corresponding decrease of the plasticity of the workpiece occurs slower than the increase thereof, and an apparatus for carrying out the method.
