Abstract
There is disclosed a shrink forming apparatus for rounding vehicular wheels and other annular workpieces. The apparatus includes a power actuated shrinker barrel assembly slidably retained for axial movement about the body of the apparatus. Rounding dies are connected to the shrinker barrel assembly for movement in a radial direction and engagement with the workpiece to perform a shrink forming operation. The apparatus further includes means for substantially eliminating the working clearance between the shrinker barrel assembly and the apparatus body during the shrink forming operation.
