  • PATENTEDJUN 1 7 I975 SHEET PATENTEDJUN 17 ms SHEET FIG. 8
  • PATENTEDJUN 17 m5 SHEET 1 HORIZONTAL CAN IRONING PRESS This invention relates to the art of can making and, more particularly, to an improved forming press for making seamless can bodies.
  • the present invention is particularly suited for making seamless can bodies from metal, such as aluminum or steel, and, accordingly, will be described with particular reference thereto. It will be appreciated, however, that the invention is capable of broader application and could be used for making seamless can bodies or similar articles from a variety of materials.
  • seamless metal can bodies are often produced by deep drawing a circular metal blank into a cupshaped member which is subsequently redrawn or ironed to elongate and thin the side wall of the blank to desired dimensions. Generally, the bottom wall of the blank is then domed axially inwardly of the side wall and the side wall is trimmed to the desired height to produce a can body having the required final size and configuration.
  • Such machines include a frame supporting at least one ram or punch for horizontal movement along a linear path between first and second positions.
  • One or more ironing rings are supported by the frame in the path of movement of the punch and between the first and second positions thereof, whereby a can blank introduced onto the end of the punch moves through the ironing ring or rings during movement of the punch from the first to the second position to achieve ironing of the side wall of the blank.
  • Such machines further generally include a doming assembly which is aligned with the punch and supported by the frame for engagement by the punch and a can blank thereon when the punch reaches its second position. The doming assembly and punch cooperate to achieve doming of the end wall of the can blank. Following such doming, the punch is returned to its first position, the can blank is stripped from the punch during initial return movement thereof, and the formed can is removed from the machine.
  • the present invention is directed to a machine of the foregoing character and in which certain of the operating components of the machine provide for improved performance, ease of assembly and adjustment, increased useful life and increased operating efficiency.
  • a can blank ironing press which includes a slide supported by the press frame for reciprocating movement to simultaneously displace a punch or punches between first and second positions relative to the frame.
  • the frame is provided with squared-off gibbing on laterally opposite sides thereof to receive squared-off guide bars mounted on the sides of the slide.
  • squared-off gibbing and support bar structure provides a simplified support bearing arrangement for the slide, and the slide guide rods add desirable stability and support for the slide during reciprocating movement thereof and especially during movement of the punch and a can blank thereon through the ironing rings.

  • the coupling member on the slide is adapted to be rotated relative to the punch to achieve threaded engagement or disengagement therebetween.
  • rotation of the coupling member is achieved by a drive gear arrangement including a drivable shaft exposed relative to the slide and rotatable relative thereto by a crank or the like, whereby the punch can be quickly assembled or disassembled from the slide to facilitate maintenance or replacement operations.
  • a unique ironing ring assembly including one or more ironing rings is provided for the punch of an ironing press.
  • the axis of each ironing ring is adjustable laterally and vertically relative to the corresponding punch axis, and the ironing ring support is adjustable relative to the press frame about a vertical pivot axis at one end of the ring support.

  • the vertical axis about which the ring support member is pivotal intersects the horizontal punch axis.
  • the pivot axis is disposed adjacent one end of the ring support member and thus pro vides for laterally aligning the ironing ring axis with the punch axis.
  • a doming assembly is provided for each punch member of an ironing press and is supported at a location for engagement by the punch member and a can blank thereon following the ironing operation.
  • the doming assembly is mounted on a horizontal sup port member extending transversely of the punch axis, and one end of the support member is interconnected with the frame for pivotal movement about a vertical axis.

By releasing the secured end of the support member, the latter can be swung horizontally to one side of the frame, whereby the doming assembly is readily accessible for maintenance purposes or the like.
  • a further feature of the present invention resides in the provision of a two punch ironing press with a pocketed discharge wheel supported by the frame for rotation about a horizontal axis.
