Description

The present invention relates to a can molding apparatus, and more particularly to a configuration for supplying compressed air, oil pressure, electric power, and processing oil to a molding tool arranged on a die table.

As a can body filled and sealed with contents such as beverages, a bottomed tubular can body having a can body (wall) and a can bottom (bottom) and a screw cap screwed to the open end of the can body. The bottle cans that have been made are known. The body of such a bottle can is squeezed diagonally so that the upper part is constricted, and a screw groove for screwing a screw cap is provided on the opening side.

When manufacturing such a bottle can, for example, a metal plate made of aluminum or an aluminum alloy is drawn into a cup shape (can base material), and then re-squeezed and side walls using a can molding apparatus. Is stretched by several stages of ironing. After adjusting the height of the can body thus obtained by trimming, printing is performed on the peripheral surface of the can body. After that, a bottle can is manufactured through a necking process in which the opening end side of the can body is drawn.

In the manufacture of such bottle cans, the bottle necker, which is a can molding apparatus used in the necking process, rotates a turntable in which a plurality of can body holding portions supporting the bottom side of the can body are arranged in an annular shape. Then, a plurality of necking dies arranged in an annular shape on the die table so as to face each can body holding portion are sequentially pressed against the opening end side of the can body held by the can body holding portion, and the steps are performed. (For example, refer to Patent Document 1).

Such a bottle necker compresses the inside of the can body through a core that supports the open end side of the can body from the inside when the necking die is pressed against the open end side of the can body to perform drawing processing. I'm sending air. As a result, the internal pressure inside the can body is increased, and deformation such as crushing of the can body due to an impact during processing of the can body is prevented.

Further, when drawing the opening end side of the can body, processing oil is supplied so as to prevent the can body from becoming hot due to plastic deformation and to cause smooth plastic deformation.
Further, electric power is supplied to the drive motor of the rotary processing tool that forms a screw groove for screwing the screw cap on the open end side of the can body.
Further, the flood control is supplied toward the hydraulic lock mechanism that fixes the die table to the rod that supports the die table.

Conventionally, these compressed air, processing oil, electric power, and oil pressure have been supplied to the necking die, the processing oil supply unit, and the hydraulic lock mechanism, respectively, via a supply path extending from the die table side.
