A base reformer assembly, and/or a base reformer roller die unit, includes a generally torpid chuck, a roller die, and a roller die unit actuating assembly. The roller die is movably disposed within the chuck. The roller die unit actuating assembly is structured to actuate the roller die. The roller die unit actuating assembly is operatively coupled to the roller die. Further, all elements of the roller die unit actuating assembly have a robust cross-sectional area.

A ram drive assembly for a can bodymaker includes a mounting assembly and a number of forming assemblies supported thereon, each including: a stationary assembly, having a die pack and a domer, and a moving assembly having a ram assembly and a cam follower assembly. The die pack defines a passage having a proximal and a distal end, with the domer disposed adjacent the distal end. The ram assembly includes a ram body having a proximal and a distal end, with the cam follower assembly coupled to the proximal end. The ram body is structured to reciprocate through the passage between a retracted and an extended position. The ram drive assembly includes: a cam having a body with a number of surfaces for engaging each cam follower assembly; and a motor having a rotating output shaft operatively coupled to the cam body for rotating the cam body.

Disclosed are a stamping method and a deep-drawing die for an aluminum alloy liner of a large-volume hydrogen storage cylinder, which solve that technical problem of low production efficiency of processing the aluminum alloy liner of the large-volume hydrogen storage cylinder by adopting strong spin and thinning of an aluminum tube in the prior art. The stamping method includes heating and stamping an aluminum ingot into a cup-shaped rough blank, then cold deep drawing the cup-shaped rough blank for thinning and lengthening into an aluminium alloy liner, and the deep-drawing die includes terrace die and thinning dies.

A bottle-shaped can in which flatness and circularity of a neck portion are improved. An upper incomplete thread portion is formed at an upper end of a thread. A height of the upper incomplete thread portion is shorter than an average height of the thread, and increases gradually toward the average height. A length of the upper incomplete thread portion between a first point and a second point is set in such a manner that an angle between a line drawn between the first point and a center point of the neck portion, and a line drawn between the second point and the center point of the neck portion falls within a range from 20 degrees to 60 degrees.

A system and method of manufacturing a metal vessel may include providing a preform being formed of work hardened aluminum. The preform may have an open portion, a closed portion, and body portion. A multiple segment mold may be closed around the preform. The multiple segment mold may include at least one projecting portion operative to partially deform the preform while closing the mold. The preform may be blow molded by causing a step-like change in pressure within the preform to cause the preform to take a shape defined by the mold when the mold is in the closed position. The molded preform may be removed from the mold.

A system and method of manufacturing a metal vessel may include inserting a preform into a mold that includes multiple segments, the preform being a work hardened metal. A pre-pressure may be applied to the preform at a first pressure level. The multiple segments of the mold may be closed, and the pressure being applied to the preform may be increased using a step function to a second pressure level after the mold is closed to cause the preform to take a shape defined by the mold.

A rotatable forming apparatus and a method for modifying a shape of a container. The rotatable forming apparatus includes a frame and a forming turret assembly. The forming turret assembly connects to the frame and includes a drive shaft, a fixed turret portion, a turret starwheel, an axially moveable turret portion and forming ram assemblies. The forming ram assemblies extend around and connect to the axially movable turret portion. Each of the forming ram assemblies includes cam followers, a forming die, a knockout tooling device and a drive cylinder. The cam followers are configured to follow a cam as the cam rotates. The forming die is operatively connected to the cam followers such that the forming die moves in the vertical direction while following the cam. The drive cylinder causes axial movement of the knockout tooling device and is configured to operate independently of the forming die.

An improved drinking can enables a user to have fluid return into the can after drinking The improved drinking can comprises a can body comprising a contoured bottom edge immediately adjacent to a bottom recess. The can body further comprising a can top mechanically coupled to a spout. Where the spout is shaped to funnel fluid back into the can body. The bottom recess is shaped to enable a first improved drinking can to sit upon a second improved drinking can where bottom recess covers can top. This protects the drinking area from becoming contaminated during shipment, storage, and display. The can body is covered with a mural where the mural is covered by a mural cover comprising a tab such that the mural cover can be removed by applying force to the tab displaying the mural.

The forming turret assembly includes a drive shaft, a fixed turret portion, a turret starwheel, an axially moveable turret portion and forming ram assemblies. The forming ram assemblies extend around and connect to the axially movable turret portion. Each of the forming ram assemblies includes cam followers, a forming die, a knockout tooling device and a drive cylinder. The cam followers are configured to follow the cam as the forming ram assemblies rotate around the stationary cam. The forming die is operatively connected to the cam followers such that the forming die moves in the vertical direction while following the cam. The drive cylinder causes axial movement of the knockout tooling device and is configured to operate independently of the forming die.

An expansion tool for expanding an article. The expansion tool includes a lead-in portion extending outwardly from a first end of the expansion tool and a first pilot portion extending from the lead-in portion. The first pilot portion has a first diameter. The expansion tool further includes a second pilot portion being generally parallel with the first pilot portion. The second pilot portion has a second diameter larger than the first diameter. The expansion tool further includes a forming portion bridging the first pilot portion and the second pilot portion. The forming portion is generally sloped. The expansion tool further includes an expansion portion extending from the second pilot portion toward a second end of the expansion tool. The expansion portion has a third diameter larger than the second diameter.
