Stamped wheel balancing weight

摘要

A wheel-balancing weight mounts to a wheel with a flange. The weight includes a body and a clip. The body is stamped by a punch to define a pocket within which an attaching portion of the clip resides. The defined pocket has a planar base and opposing side walls generally perpendicular to the base. The body as stamped by the punch includes a pre-stake for each side wall external to the pocket and adjacent the side wall, and an undercut for each side wall within the pocket and generally located at a juncture of the side wall and the base.

1. A wheel balancing weight for mounting to a wheel with a flange, the weight including a body and a clip, the body for providing a predetermined mass to the weight and the clip for securely grasping the flange to secure the weight thereto, the body being stamped at an attaching face thereof by a punch to define a pocket in the attaching face within which an attaching portion of the clip resides, the defined pocket having a planar base and opposing side walls generally perpendicular to the base, the body also being stamped by the punch to include a pre-stake in the attaching face for each side wall external to the pocket and adjacent the side wall, and an undercut for each side wall within the pocket and generally located at a juncture of the side wall and the base,
each pre-stake being defined in the body to include a formed ridge of material exterior to the pocket and immediately adjacent a respective side wall thereof, the ridge following the side wall and being bordered on a first lateral side thereof by such side wall and on a second lateral side thereof by a notch formed by a cutting edge of the punch, the notch having a V-formation in cross-section, including a relatively shallower wall proximate the side wall and a relatively steeper wall distal from the side wall.
