    Abstract: New tooling technology for deep drawing one-piece can bodies from flat-rolled sheet metal can stock (58) which is precoated on both surfaces with an organic coating and draw lubricant. A draw die curved-surface cavity (122) entrance is formed using a radius of curvature (132) with a practical maximum of about five times nominal sheet metal thickness gage; and, preferably is formed about multiple radii of curvature (R.sub.L, R.sub.S, R.sub.L) to increase surface area (140) without increasing projection on the clamping plane. Die cavity wall (156) is tapered about 1.degree. to provide increasing cross section with increasing penetration of draw punch (160). Redraw die (90) has a sleeve-like configuration in a cross sectional plane which includes its central longitudinal axis (70); such configuration enables increase in production rate by enabling coaxial relative movement of such die into work product registry (98, 99) which position cups for redraw. The outer juncture (168) of such die sleeve is also formed about multiple radii of curvature (174, 180); and, the clamping space, between respective planar surfaces (96, 104) of die (90) and clamping ring (101) is tapered so as to decrease in vertical cross section in approaching die cavity (62).

    Abstract: Apparatus and method for coating the top surface of a high speed metal sheet with a thin film of lubricant having a uniform thickness. The apparatus includes a header assembly positioned above the moving sheet, a plurality of spray nozzles inclined at an angle relative to the oncoming sheet, and a solenoid operated valve to control flow of lubricant through each of the spray nozzles. The orifice of each nozzle is sized to produce a mist. The angle of inclination of the spray nozzles is sufficiently large so that the mist is generally sprayed above rather than toward the sheet. The method includes selecting a specific spray nozzle arrangement and adjusting the header assembly so that the span of the mist corresponds to the width of the metal sheet. An extremely thin and uniform thickness of lubricant film is formed on the sheet as the particles of mist settle onto the sheet. Waste of lubricant is minimized.

    Abstract: A precoated stock material for use in forming a drawn and ironed container and a method of forming such container is disclosed herein. The stock material initially has a layer of lubricant applied to one or both surfaces of the metal base with the lubricant consisting essentially of a fatty acid ester of a mono or polyhydric alcohol and having a distribution of less than 3 mg./in..sup.2. The method contemplates applying the layer of lubricant to a metal stock, such as aluminum, black plate or tinplate, cutting a disc from the metal stock, and transforming the disc into a drawn and ironed container without additional lubricant being applied to the tooling.
