Abstract: Beverage can manufacturing apparatus is provided in the form of a set of N necking stations S1, S2 . . . SN for progressively necking a beverage can body having a diameter greater than or equal to 2.8 inches to result in an open end designed to receive a first standard end. The necking stations are constructed such that a subset of the necking stations Si . . . Sj, where 1?i<j<N, progressively neck the beverage can body to result in an open end designed to receive a second standard end for the beverage can. The diameter of the first standard end is less than the diameter of the second standard end. For example, the first standard end is say a 202 standard end and the second standard end is a 209, 204, or a 206 standard end. Alternatively, for example, the first standard end could be a 206 end and the second standard end could be a 209 standard end.

Abstract: A method for cold expansion of a hole formed in a work piece. The method comprises providing a body comprising at least a cylindrically shaped part having an inner hole in axial direction of the body. The body further comprises along its circumferential direction a plurality of members which are movable in radial direction of the body, such that the outer diameter of the cylindrical part of the body can be changed.

Abstract: The invention relates to a method for extracting a die (4) from a hollow object (11) having several grooves (16, 17) arranged opposite one another on the surface of the inner sheath whereby the longitudinal axes thereof extend crosswise relative to the corresponding longitudinal central planes (i.e. cross-grooves), whereby said die (4) is part of a tool (10) having a matrix (1) for forming the hollow object (11) and several other die segments (9a, 9b) arranged opposite one another relative to the central axis (2) thereof. Each of said die segments has an outer ridge (21a, 21b); in order to form the hollow object, said die segments (9a, 9b) are expanded into a working position, whereby the ridges (21a, 21b) are fitted into corresponding grooves (16, 17), and extracted after the hollow object (11) has been formed.

Abstract: An oil pan includes an oil reservoir and a pair of side walls facing the reservoir. A bulge is formed in each side wall. Each bulge defines an oil sub chamber connected to the oil reservoir. The bulges are formed integrally with the side walls by deforming the side walls outward. In other words, the bulges are not fastened to the side wall but are part of it. The oil pan is therefore easily and inexpensively formed by pressing. Further, since there is no joint between each bulge and the side wall, the oil pan has improved strength and durability.

Abstract: An apparatus for reducing the diameter of an open end of a container is claimed. The apparatus comprises a housing having a longitudinal axis. A die is supported in the housing about the longitudinal axis. A radially expandable pilot member is also supported in the housing. The radially expandable pilot member is selectively moveable between a contracted position and an expanded position relative to the longitudinal axis. The radially expandable pilot member comprises a plurality of forming members. A method which utilizes the apparatus is also claimed.

Abstract: A device for embossing metal pipe is disclosed. The device includes a core having a plunger hole and a plurality of core pass through holes perpendicular to the plunger hole. The device also includes a plunger for moving through the plunger hole to push the punches in the core pass through holes selectively away in a direction perpendicular to the axis of the core.

Abstract: In order to obtain uniform pressing force applied to a workpiece by an ironing die and easily disengage the workpiece after completing plastic working for the workpiece, a forming machine for performing the plastic working for the workpiece has a base pedestal, a forming punch provided on the base pedestal, and an annular ironing die arranged over the forming punch. The forming punch comprises a main punch body, six punch collets to be engaged with the main punch body and separated from each other at equal angles, a metal sleeve externally fitted to the main punch body and the punch collets, and a holder for holding the metal sleeve.

Abstract: The present invention generally relates to an external cylindrical or conic section shaped fixture which is tightly fit around the same shaped workpiece prior to expansion forming to a final dimension. During expansion forming, the external fixture is also deformed and is therefore designed for one-time use. The external cylindrical or conic section shaped fixture of the present invention is particularly useful for expansion forming of workpieces which contain brazed lap joints. The external fixture restrains, out-of-plane joint rotation and reduces the stress concentrations existing near the lap joints. Additionally, the external fixture provides additional load carrying capability to allow better load distribution during expansion forming. No change is required to the expansion forming machinery or the inner expander dies (jaws) with use of the present invention.
