PROCESS FOR PRE-FORMING CYLINDRICAL TUBES INTO TUBULAR MEMBERS HAVING SHARP CORNERS |
摘要 |
A method of forming a tubular member with portions having finished corners formed in a hydroforming operation by initially forming a pre-form that includes sharp corners. The pre-form includes bulges of the tube material between the sharp corners that flow toward the intended corner locations as the tubular member is hydroformed. The bulges may be external ribs or internal recesses.
