Abstract
A ram that is utilized in high speed apparatus for forming elongated one piece metal can bodies from shallow cups is constructed by metallurgically bonding either a nose piece to a body or a tail piece to a body, the body constructed from a single integral piece having an elongated thin walled tube section with either a tail piece section or a nose piece section for connection to a drive means.
Claims22
A lightweight ram for high speed apparatus that produces relatively elongated can bodies by driving relatively shallow cups through a ring type die means, said ram including:
- a nose piece constructed to mount and operatively position a punch on said ram;
- a body constructed from a single integral piece having an elongated thin-walled tube section with a front end and tail piece section adapted for connection to a drive means that reciprocates the ram along its longitudinal axis;
- said nose piece, said tube section and said tail piece section being in axial alignment, with said tube section interposed between said nose piece and said tail piece section;
- a metallurgical bond fixedly securing said nose piece to said tube section at said front end and extending forward thereof.
A lightweight ram for high speed apparatus that produces relatively elongated can bodies by driving relatively shallow cups through a ring type die means, said ram including:
- a nose piece, a body and a tail piece, in which the ram consists of two elements which are metallurgically bonded together to form a unitary structure;
- the nose piece constructed to mount and operatively position a punch on said ram;
- the body having an elongated thin-walled tub section;
- the tail piece constructed for connection to a drive means that reciprocates the ram along its longitudinal axis;
- and
- said nose piece, said body and said tail piece being in axial alignment, with said body interposed between said nose piece and said tail piece.
