ABSTRACT:
The invention relates to a method for forming and manufacturing the automobile rear axle housing from an integral steel tube, and to the special equipment for using the said method. The method involves cutting a longitudinal through opening in the center of the steel tube, expanding the opening with an expanding device and after expansion, roll-pressing or pressing the tube wall into the required form. The equipment designed for using this method comprises an operable die set, tube end thrust unit, opening expansion unit, roll-press unit and press unit. The use of this invention for making the automobile rear axle housing will omit the welding process, improve product quality, reduce manufacturing cost and the investment for equipment.
