Abstract
In order to provide a balanced bent lip disc, the applicant routinely had issues with rippling at an outer circumference edge of the lip. Due to the geometries involved in a 3½ inch disc bent to provide an outer lip of ½ inch at 45 degrees, 0.1145 of excess circumference is created thereby providing a ripple effect. The applicant discovered that simultaneously embossing the lip while bending the lip could reduce this rippling effect (and the outer circumference at the edge) by at least 75 if not 90 or 95% of a non-embossed lip bent in the same manner.
Claims19
A method of forming a rotationally balanced disc with an angled outer lip comprising the steps of:
- a) providing a round disc blank;
- b) bending the disc blank to provide the angled outer lip at a predetermined angle at a transition relative to a center disc portion;
- and
- while bending the disc blank, simultaneously embossing a pattern into the lip in a single step with the bending step, thereby reducing a radial edge length at an outer edge of the outer lip by removing at least 75% of extra material at the outer edge created by the bending step over a non-embossed lip bent in the same manner while providing a rotationally balanced disc with the outer edge at the outer lip being round.
The method of 1 wherein the step of providing the disc blank further comprises providing one of cutouts and a central bore in the disc blank.
