Abstract
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.
Claims13
A can body maker comprising:
- 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 pressing 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.
A frame for a drive mechanism provided in a can body maker having a ram shaft which has a punch provided at a front end portion thereof, a die in which a through hole into which the punch is inserted is formed and a cup-shaped body extruded by the punch is passed through the through hole to perform drawing processing and ironing processing on the cup-shaped body, a cup holder which presses the cup-shaped body against an end face of the die, and a drive mechanism reciprocating the ram shaft, to house the drive mechanism,
- wherein the drive mechanism has a reciprocating linear motion mechanism reciprocating the ram shaft,
- wherein the reciprocating linear motion mechanism has a housing in a cylindrical shape, and
- wherein the frame for a drive mechanism is formed by side plates, a bottom plate, a front plate, and a back plate being integrally fixed to each other, and a circular opening surrounding a circumferential surface of the housing to house the reciprocating linear motion mechanism is integrally formed in the back plate.
