METHOD OF WHEEL MANUFACTURE FOR CORRECTING ROTATIONAL NON-UNIFORMITY OF A PNEUMATIC TIRE AND WHEEL ASSEMBLY, APPARATUS FOR PERFORMING SUCH METHOD AND THE RESULTING WHEEL |
摘要 |
<p>In an apparatus (50) for forming bolt and center-pilot mounting openings in vehicle wheels, particularly styled-disc vehicle wheels, a preformed rim and disc assembly is engaged and fixtured around the rim bead seat with the inboard disc face resting on a lower die assembly (82) and without plastic deformation to the rim or disc. An upper die assembly (52) having an array of bolt hole punches (56) is moved into piercing-and-coining engagement with the disc to form the bolt openings. Continued motion of the upper die assembly (52) pushes the disc and lower die assembly (82) into shearing engagement with a center punch (76) which forms the center-pilot opening.</p> |
