    Abstract: The hot stretch forming of sheet metal alloys, such as highly deformable aluminum alloy materials, is improved by using a lubricant comprising bismuth between the forming tool and the engaged surface of the sheet metal. A precursor of bismuth, such as bismuth subsalicylate, may be dispersed in a liquid and applied to the sheet metal before the sheet is heated to its forming temperature. Other lubricants such as boron nitride may be combined with the bismuth precursor. The precursor compound is decomposed to bismuth (or bismuth and carbon in the case of bismuth subsalicylate) which lubricates contact between the surface(s) of the sheet and the forming tool during forming and removal of the formed part from the tool.

    Abstract: The invention concerns components of food cans (1), can bodies (6), and ends fabricated starting from a stratified construction constituted by a foil of plastic material on each of the faces of which adheres a metal foil and their fabrication process. The components are characterized by the nature of the material, metal-polymer-metal construction and by the fact that ratio of the plastic thickness to the sum of the metal thicknesses is greater than 0.5. The fabrication process is drawing in one or several passes characterized preferably by the particular shape of the punch and of the die plates. The invention applies equally to the fabrication of food cans as to ends for food cans or for beverage cans.

    Abstract: Draw processing flat-rolled sheet metal substrate preselectively precoated on each surface with organic coating and draw lubricant into one-piece can bodies ready for assembly into sanitary packs free of any requirement for washing, organic coating or repair of organic coating after fabrication and before such direct usage. Selective organic precoating includes embodying a blooming compound which is made available as draw lubricant responsive to heat and/or pressure of draw forming; also, surface application of a draw lubricant after curing of the organic coating. Combined lubricant on each surface is verified before start of fabricating. Draw-forming of tensile strength sheet metal is controlled over side wall height by clamping solely between planar clamping surfaces and by interruption of draw to establish a flange at the open end of cup-shaped work product. Surface area of the cavity entrance zone for each die is preselected along with curved surface transition zone on draw punch in relation to sheet metal substrate starting gage. Nesting of curvilinear clamping surfaces of the prior art is eliminated during redraw of work product. The curved transition zone of cup-shaped work product is reshaped prior to redraw.

    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: New technology for fabricating a one-piece cup-shaped can body having a protective organic coating as formed. Such can body is formed free of side wall ironing from can stock comprising flat-rolled sheet metal substrate precoated with protective organic coating and forming lubricant. A plurality of successive diameter-reduction operations are carried out on a planar blank and cup-shaped work product under tension during which side wall height is increased and side wall substrate is decreased in thickness to provide controlled uniformity in side wall substrate thickness over about 85% to about 95% of side wall height for such can body. The fabricating tooling provides for a preselected clearance between a punch peripheral wall and a die cavity internal wall in each of such plurality of diameter-reduction operations to achieve a desired decrease in side wall thickness as the precoated substrate is moved into a die cavity by relative movement of its respective punch.
