METHOD OF FORMING INTERNAL SCREW PROFILES ON HOLLOW THIN-WALLED BLANKS

摘要

A method of forming internal screw profiles on hollow thin-walled blanks, at which compression is carried out by an end working surface of a cylindrical deforming tool, whose angular velocity of rotation around its own axis is determined by the formula,where- angular velocity of rotation of the cylindrical deforming tool; - angular velocity of the blank; - radius of the blank;- average radius of the face of the cylindrical deforming tool.
