Appl. No.:

12/941046

Inventors:

Damon Douglas Brink - Ventura CA, US

International Classification:

B21D 51/16

US Classification:

604264, 72324

Abstract:

A novel method to fabricate a needle includes stamping an elongated shape in a flat metal sheet. The elongated shape defines a longitudinal axis and two edges that are substantially parallel to the longitudinal axis. Each of the two edges includes an inward curve with relative alignment to create a relatively narrow neck. A longitudinal channel is formed to give the elongated shape a U-shaped cross-section in a plane normal to the longitudinal axis. The method includes punching through the neck with a punch that slides along a punching axis that intersects the longitudinal axis with an angle in the range 15 to 50. Alternatively the method includes coining a thinned region that spans the neck and may define a V-shape in a major plane of the flat metal sheet, and separating the elongated shape along the thinned region after coining.
