Abstract

The first stage of the punching operation is done using a spherical punch (11) over the conventional circular die orifice (4). This forms the spherical seating (36) and the beginning of the slug (3a). The second stage is done over a larger diameter die orifice with a matching punch and removes the slug, leaving a clearance hole. This type of hole is utilized in commercial vehicle wheels where the base of the wheel nut has a spherical form for self centring action.
