Method and device for producing a prismatic battery cell container
The invention refers to a method and an apparatus (20) for manufacturing of a prismatic unilaterally open battery cell container (21). First an extruded container (41) is formed from a slug (38) by extrusion. The slug (38) consists of a uniform material. The extruded container (41) is then formed by a first ironing in a first ironing station (25) and by a second ironing in a second ironing station (28). During ironing the container is moved by a respective ironing ram (26, 29) only partly through an associated die tool (27, 30) and is reversed when reaching a reversal point (U). After the second ironing a remaining edge (82) of the obtained intermediate container (77) is separated, thereby the battery cell container (21) is obtained.
METHOD FOR FORMING A MOULDING AND MOULDING
A shaped part and a method for forming the shaped part from a lightweight metal or alloy by extrusion of a slug performed along a pressing axis. The shaped part is formed in at least one region with a deviation from a basic form that is rotationally symmetrical with respect to the pressing axis. The symmetry-deviating region extends over a wall portion of the shaped part that is formed by backward cup extrusion with a normal vector extending predominantly orthogonally in relation to the pressing axis. The same extruding operation forms a structure that surrounds the pressing axis, on a sheet-like base of the shaped part that adjoins the wall portion and has a normal vector extending predominantly in the direction of the pressing axis on the side thereof opposite from the wall portion. In a region of lowest wall thickness of the wall portion at the transition to the base, the quotient of this wall thickness in mm and an average curvature (1/r) in mm.sup.-1, formed at the transition, is greater than 0.03 and/or, in an at least predominant region of the base-wall transition when seen in the circumferential direction, the ratio of the wall thickness to the base thickness is less than 1.0.
Long cartridge case
A method and tooling for forming a cartridge case blank comprising backward extruding a tube from a length of wire stock in multiple backward extrusion steps with progressive tooling to obtain an intermediate blank that can be finish drawn without a preceding annealing step and which if otherwise not subjected to multiple backward extrusion steps, would require annealing prior to finish drawing to avoid tearing.
ALUMINUM ALLOY FOR IMPACT EXTRUDED CONTAINERS AND METHOD OF MAKING THE SAME
Novel aluminum alloys are provided for use in an impact extrusion manufacturing process to create shaped containers and other articles of manufacture. In one embodiment blends of recycled scrap aluminum are used in conjunction with relatively pure aluminum to create novel compositions which may be formed and shaped in an environmentally friendly process. Other embodiments include methods for manufacturing a slug material comprising mixtures of aluminum alloys for use in the impact extraction process, a container manufactured using the aluminum alloy in an impact extrusion process, and the container, wherein the material of the container is the aluminum alloy.

Metallic roll-on container
An aluminum roll-on container, and a method of manufacturing the same, retains a roller sphere for applying a product onto an external surface. The roller sphere can both rotate and move within the container, and a chamber is formed between the container and the roller sphere. In a first position of the roller sphere, the chamber forms a continuous volume with the interior volume of the container such that the chamber receives a product stored in the container volume. Then, in a second position, the chamber forms a continuous volume with the external environment such that rotation of the roller sphere transfers the product from the chamber to an external surface. A relationship between the roller sphere and an upper opening of the container allows the roller sphere to be pressed into the container and then retained in the container.

Method for fabricating non-planar magnet
A method for fabricating a non-planar magnet includes extruding a precursor material including neodymium iron boron crystalline grains into an original anisotropic neodymium iron boron permanent magnet having an original shape, wherein the original anisotropic neodymium iron boron permanent magnet has at least about 90 percent neodymium iron boron magnetic material by volume. The original anisotropic neodymium iron boron permanent magnet is heated to a deformation temperature. The original anisotropic neodymium iron boron permanent magnet is deformed into a reshaped anisotropic neodymium iron boron permanent magnet having a second shape substantially different from the original shape using heated tooling to apply a deformation load to the original anisotropic neodymium iron boron permanent magnet. The original anisotropic neodymium iron boron permanent magnet and the reshaped anisotropic neodymium iron boron permanent magnet each have respective magnetic moments substantially aligned with a respective local surface normal corresponding to the respective magnetic moment.
HYDRAULIC FORMING MACHINE AND METAL BALL FORMING MACHINE
A hydraulic forming machine, including a body provided with a feed inlet penetrating a first mounting surface, a cutting mechanism, a forming die, an ejector arranged on the forming die, and a driving mechanism. The forming die includes a movable die and a fixed die matched with each other. The cutting mechanism and the fixed die are provided on the first mounting surface of the body and respectively at two sides of the discharge end of the feed inlet. The movable die is arranged on the driving mechanism and driven by the driving mechanism to move close to or away from the fixed die in a direction perpendicular to the first mounting surface. The cutting mechanism is configured to cut a blank at an output end of the conveying inlet. The blank cut by the cutting mechanism is extruded between the fixed die and the movable die.
