ADJUSTABLE TWIST BEAM TUBE FORMING DIE

摘要

A die 20 used to form a metal tube into a tubular twist beam part 22 having a U-shaped torsion section 66 is provided. The die 20 includes a punch 44 and side form blocks 34 which simultaneously engage a metal tube and form the metal tube into the tubular twist beam part 22. The form blocks 34 have a curved profile which depends on the desired profile of the tubular twist beam part 22 to be formed. The die 20 includes horizontal spacer blocks 38 and vertical spacer blocks 32 restricting movement of the punch 44 and form blocks 34. The spacer blocks 32, 38 can have various different dimensions and can be easily removed and replaced to adjust the closing position of the die 20 and thus form multiple tubular twist beam parts 22 each having a different dimension and different roll rate.
