A spin-roll formed one-piece field core shell formed from a blank disc of sheet metal. The one-piece field core has an outer annular ring integral to and encircling a center axis of the disc and extending from a bottom external surface in a direction that is perpendicular to the bottom surface of the disc and parallel to the center axis of the disc. The core has an inner annular ring integral to and encircling a center axis of the disc, the inner annular axis is spaced radially inward from the outer annular ring and extends from the bottom external surface in a direction that is perpendicular to the bottom surface of the disc and parallel to the center axis of the disc. The one-piece field core also contains a mounting flange that encircles a center axis of the disc and extends in a perpendicular direction to a top external surface of the disc and parallel to the center axis of the disc. The mounting flange includes a bore that extends from the top of the mounting flange to the bottom external surface of the disc.

A method for forming a hub having blind bore with an elevated blind bore face is provided. The blind bore face is elevated relative to the upper surface of an annular disc from which the hub is integrally formed, by first displacing metal radially inward from the upper surface toward the center of the disc to form an elevated surface with a hole therethrough, and second displacing metal radially inward, again from the upper surface toward the center of the disk, to form a hub which incorporates a blind bore having an elevated surface. A blind bore hub formed by the foregoing method is also provided.

Blind bore hub and method of forming

A method for forming a hub having blind bore is provided. The blind bore hub is formed integrally with a solid circular disc by displacing metal radially inward from the upper surface toward the center of the disc to form a hub, and then punching a bore opening through the center of the hub to provide a blind bore therein. A blind bore hub formed by the foregoing method is also provided.

A tool support and monitoring assembly for a press. The tool includes upper and lower die shoes, back-up plates, and upper and lower die tooling. The die tooling is secured to the back-up plate and includes a first surface facing the back-up plate and an opposite second surface. The back-up plate defines an air plenum which is connected to a pressure monitoring device. The die tooling defines a plurality of small bores which communicate with the air plenum. The bores extend from the first surface toward the second surface of the die tooling. The pressure monitoring device detects air pressure in the air plenum and bores, and shuts down the press to prevent a subsequent stroke when a pressure drop indicative of tool failure is detected.
