Abstract
A device is disclosed for stripping a cup-shaped metal can blank from the end of a reciprocable ram of a can ironing press. The device includes a plurality of stripper members circumferentially spaced apart about an axis aligned with the ram axis. Each of the stripper members is supported for pivotal movement about a corresponding axis transverse to the ram axis and is individually captured against axial, circumferential and radial displacement relative to the ram axis. Each stripper member includes a nose portion adapted to engage behind a can blank on the ram to strip the blank therefrom, and the nose is biased radially inwardly of the ram by a corresponding adjustable spring mechanism.
Claims22
A device for stripping a cup-shaped article from the end of a reciprocable ram comprising:
- stripper member support means having an opening therethrough to freely receive said ram and article, a plurality of stripper members circumferentially spaced apart with respect to the axis of said opening and each having an article engaging end pivotal radially of said opening axis, said stripper member support means including means defining a plurality of separate pockets each receiving a corresponding one of said stripper members in detached relationship with respect thereto, each said pocket alone confining said corresponding one of said stripper members axially, circumferentially and radially with respect to the axis of said opening and for pivotal displacement of said article engaging end of the corresponding stripper member radially inwardly and outwardly relative to said axis, and separate biasing means for each stripper member, said biasing means acting against the corresponding stripper member to bias the article engaging end thereof radially inwardly of said axis of said opening.
A device for stripping a cup-shaped article from the end of a reciprocable ram comprising:
- plate means having opposite sides and an opening therethrough to receive said ram and article, said plate means including means defining a plurality of circumferentially spaced apart pockets between said opposite sides and having inner ends communicating with said opening and outer ends spaced radially from said opening, each of said pockets including axially spaced apart radial end faces, circumferentially spaced apart side faces, and radially spaced apart inner and outer surfaces at said outer end, a radially pivotal stripper member in each of said pockets and detached with respect thereto, said stripper member being radially, axially and circumferentially confined in said pocket and including a first portion in said outer end of said pocket and a second portion extending radially from said first portion and through said inner end of said pocket, said first portion of said stripper member including means disposed between said inner and outer surfaces at said outer end of said pocket to radially confine said stripper member, said second portion of said stripper member including side walls facially engaging said side faces of said pocket to circumferentially confine said stripper member, and said first and second portions of said stripper member including axially spaced wall means facing said end faces of said pocket to axially confine said stripper member, said means on said first portion of said stripper member including means defining a stripper member pivot edge at said inner surface in the outer end of said pocket, said second stripper member portion having a stripper nose in said opening through said plate means, and individual spring means for each said stripper members, each said spring being supported by said plate means and acting against the corresponding stripper member to bias said stripper nose to pivot radially inwardly of said opening about said pivot edge.
