Abstract

Apparatus for forming the bolt openings and/or the center-pilot opening in a vehicle wheel that includes a circumferential array of locating jaws for engaging and locating the rim portion of the wheel. An upper die is reciprocable for forming at least one mounting opening on a first axis in the disc portion of a wheel engaged by the locating jaws. The locating jaws are movable between a first or outer position, and a second or inner position radially inward of the outer position and in which the locating jaws engage the rim portion of the wheel positioned within the locating jaws. A ring mechanism surrounds the first axis and is disposed for radial abutment by the mechanism for moving the locator jaws at the second or inner position of the locator jaws so as to define the second or inner position of the locating jaws concentrically with each other on a second axis, which may be either concentric with or eccentric to the first axis.
