Abstract (en)

A can body maker includes a ram shaft extending in a front-rear direction, a punch disposed at a front end portion of the ram shaft, a reciprocating linear motion mechanism connected to a rear end portion of the ram shaft to reciprocate and linearly move the ram shaft in the front-rear direction, a die having a through hole into which the punch is inserted, a cup holding mechanism which presses a cup-shaped body against an end face in which the through hole of the die opens, and a cup holder drive mechanism that oscillates the cup holding mechanism in the front-rear direction, wherein the cup holder drive mechanism has a cam structure and is disposed directly below the cup holding mechanism.
