초록

A method of forming a housing which includes roll forming a steel tube radially inwardly with a plurality of rollers each having a rolling axis parallel to the longitudinal axis of the tube, the rollers compressing the tube and forming reduced diameter portions and enlarged diameter portions. The method then includes cutting the tube perpendicular to the longitudinal axis generally midway through an enlarged diameter portion and a reduced diameter portion, forming a plurality of mirror image preforms. Finally, the method includes cold working the preform...

1. A method of forming a housing, comprising the following steps: roll forming a steel tube radially inwardly with a plurality of rollers each extending perpendicular to a longitudinal axis of the tube, each roller having a rolling axis parallel to the longitudinal axis of the tube, the rollers compressing the tube and forming reduced diameter portions and enlarged diameter portions in the tube;cutting the tube perpendicular to its longitudinal axis generally midway through an enlarged diameter portion and a reduced diameter portion, thereby forming a pl...
