  • Patent number: 4640116
    Abstract: A press for converting ends for cans and the like is provided with a conveyor extending sideways through the press to carry shells for processing into can ends along an end converting path. Upper and lower conversion tooling is located along the end converting path at the top and bottom of the conveyor, defining a plurality of stations on opposite sides of the center of the tooling for working progressively on shells moved by the conveyor along the end converting path. First and second tab tooling, auxiliary to the main tooling means, is located on opposite sides of the conveyor extending transversely thereof and defining a tab forming path which bridges the end converting path. Opening tabs are formed from a strip of metal stock fed through the tab tooling and the strip with completed tabs is guided in a loop from the tab tooling back to a staking and attachment station on the end converting path for removal from the strip and attachment to the shells.

  • Patent number: 4631950
    Abstract: A progressive forging machine is disclosed in which a tool pack is removably mounted on the machine to facilitate tool changeovers and the like. The tool pack includes tool carriers guided in bearings on the tool pack for reciprocating movement by a bolster mounted on the machine frame. Because the tools are guided by the tool pack itself, inaccuracy of bolster alignment does not adversely affect the position of the tooling. The tool pack also provides a shear, a transfer, strippers, and kickouts for both the dies and the tools. The drives for the various components on the tool pack are provided on the main machine frame and are either automatically connected during installation of the tool pack or are easily connected at the time of such installation. Because the tooling is guided by the tool pack itself, deflections within the main machine frame created by forming loads do not adversely affect tooling alignment.

  • Patent number: 4627265
    Abstract: A conversion system for converting plain container end pieces into easy-open end pieces in a single press includes multiple slides, all driven by the press and carried within the confines of the press frame but independently adjustable and controllable. At least one of the slides carries conversion tooling and the other carries tab forming tooling and is arranged adjacent the conversion tooling so that the tab strip may be fed into the conversion tooling for attachment of the tabs to the end pieces by the conversion tooling. High speed feed rolls having helical gripping grooves are also provided to feed plain end pieces to the conversion tooling for forming and for attachment of the tabs.

  • Patent number: 4627264
    Abstract: A cam actuated ejector is provided with a shell press having a crankshaft for reciprocating a slide to which die tooling is mounted and having a forming station in which the die tooling forms a part to be ejected. The ejector includes a kicker bar slidably received within a recess in the press and which is in close proximity to and substantially coplanar with a part to be ejected. The kicker bar is positively reciprocated by a cam assembly that is synchronously engaged with the crankshaft, which operates the press slide, such that an end of the kicker bar cyclically moves at a first rate of movement from a first position outside the forming station to an intermediate position wherein the end contacts a part to be ejected.

  • Patent number: 4626157
    Abstract: In a metal can at least one component having an edge portion forming part of a seam is made from pre-laminated plate comprising a metal substrate with a polymeric film bonded over the whole of one or both of its sides. An aerosol valve cup is made from such plate with its underside having such a polymeric layer, and is secured to the can body in a seam by conventional mechanical deformation, such as swaging, so as to compress the polymeric layer in the seam. This provides a satisfactory seal without the need for any additional sealing material within the seam.

  • Patent number: 4626158
    Abstract: A triple seam for assemblying a bottom to a container body, and a process for forming the triple seam. The process comprises the step of forming an axially extending seaming structure comprising a plurality of layers belonging to adjoining edges of the body and bottom. One of the adjoining edges includes a first layer and a contiguous overfolded second layer having an axial length less than the axial length of said first layer to increase the number of layers in a first axial section of the seaming structure. The process also includes the step of lamination rolling the seaming structure to a uniform width. A hook-shaped profile is formed in said body edge as a preliminary step in this process.

  • Patent number: 4622837
    Abstract: The conduit bending tool of this invention has on its body a pair of pads which are spaced apart in the direction lengthwise of the arcuate bending shoe and which define recesses that open to one side of the body wherein end portions of a straight cylindrical spirit level vial are closely receivable. Cement on a surface of each recess that embraces the vial partway around it secures the vial in place. The pads and recesses are defined by one of the two main mold elements that form the body, which have their parting place on a plane of symmetry in the body, and the vial is installed by simply inserting it into the recesses.

  • Patent number: 4621964
    Abstract: In the formation of a valve mounting assembly for aerosol containers and the like, an aerosol valve mounting cup including a projecting central cylindrical body with an outwardly directed annular channel about the end thereof, an annular planar gasket deformably receivable within the channel, and apparatus for positioning the gasket in the channel. The inner periphery of the gasket defines a diameter substantially less than that of the cylindrical body whereby forceable engagement of the gasket about the body and into the channel outwardly deforms the inner peripheral portion of the gasket into a sleeve-like configuration intimately engaged with the cylindrical body thereabout, the remainder of the gasket seating within and conforming to the annular channel. Engagement of the gasket into the channel utilizes a gasket receiving bushing with a longitudinally moveable inserter therein which forces the gasket into the channel as the apparatus moves over a mounting clip.

  • Patent number: 4621514
    Abstract: To form a commutator segmental ring, an intermediate stage commutator ring (4) is formed from a flat strip (1) of commutator material which is bent into essentially cylindrical tubular shape to form a blank (2) having a gap or crack (3) adjacent the ends of the strip. The commutator ring, upon forming of the commutator, is severed into commutator segments. The gap or crack of the blank is aligned with a ridge or rib in a forming punch press to form a groove within the essentially cylindrical tubular blank (2) so that, when the intermediate stage commutator ring (4) is made, a cylindrical portion (5) already dimensioned for the intermediate segmental ring and a flange portion (6) are made, with a groove in alignment with the gap or crack obtained during cold-flowing of the metal in the press by the guidance afforded by the rib or ridge in the gap or crack of the cylindrical tubular blank.

  • Patent number: 4616497
    Abstract: A method of uniformly rotopeening the inside walls of metallic tubes to a desired final peening intensity by means of at least one rotatable peening flapper is disclosed herein. The method generally comprises the step of simultaneously rotating and orbiting the flapper within the tube while maintaining a selected stand-off distance between the inner edge of the flapper and the inside wall of the tube. The angular speed of the flapper and the stand-off distance are selected so that the slope of the curve defined by peening intensity over time is substantially flat in the vicinity of the desired final peening intensity. The method is particularly useful in uniformly and accurately peening the inside walls of the heat exchange tubes anchored in the tubesheet of a nuclear steam generator in order to relieve tensile stresses in the walls of these tubes which might otherwise lead to stress corrosion cracking in the tube walls.
