Method of manufacturing structural components from tube blanks of variable wall thickness |
摘要 |
A method for forming a tubular structural member includes the steps of cold forming a tube blank (10) to have a longitudinally variable but circumferenfially constant wall thickness (t1, t2, t3) and forming the blank into the desired structural member (90). Preferably, the forming step involves hydroforming.
