Benefits of technology
The can making machine described in this patent has two motors that drive the main parts of the machine: the crank and the table. In traditional machines, these parts are connected, but in this new design, they are separate. This has two benefits. First, it makes it easier to change the distance between the table and the crank, which can be used to make cans of different heights without changing the top and bottom dead centers. Second, it makes it simpler to operate the machine.
Problems solved by technology
However, in the conventional can making machine, it was difficult to change an effective stroke of the processing table, and it was possible to make only cans of a constant drawing depth (processing height).
That is, it was not possible to flexibly respond to a demand for increasing the processing height, such as performing the drawing process deeper than the conventional can.
However, in this case, not only does the structure of the apparatus become complicated, but the crank radius also changes after the stroke adjustment, and the top dead center and the bottom dead center of the processing table change accordingly.
Accordingly, the adjustment workpiece is also cumbersome.

Embodiment Construction
[0043]Hereinafter, a can making machine 1 according to an embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, a can making machine 1 of the present embodiment is a so-called bottle necker which makes a bottle can (can) B of a desired shape, by performing various types of bottlenecking including die processing and rotary processing on a cylindrical body W having a bottomed cylindrical shape.
[0044]A cylindrical body W supplied as a workpiece to the can making machine 1 is a DI can subjected to drawing & ironing (DI) processing, printing and coating in a previous process. The DI can is formed in a bottomed cylindrical shape, by applying a cupping process (drawing process), a DI process (drawing and ironing process), a trimming process, a printing process, a coating process and the like to a disk-like blank punched out from a plate material such as an aluminum alloy material.
[0045]The cylindrical body W includes a cylindrical periphera...
