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 circumferentially constant wall thickness (t1, t2, t3) and forming the blank into the desired structural member (90).
