Abstract

A forming assembly for use in a can bodymaker includes a stationary assembly and a moving assembly movably coupled to the stationary assembly. The stationary assembly and the moving assembly are a unified assembly that is structured to be selectively coupled to a mounting assembly body of the can bodymaker. The moving assembly is structured to be selectively coupled to a ram drive assembly of the can bodymaker and moved with respect to the stationary assembly thereby.

First claim

What is claimed is:

1. A forming assembly for use in a can bodymaker, the forming assembly comprising: a stationary assembly; and a moving assembly movably coupled to the stationary assembly, wherein the stationary assembly and the moving assembly are a unified assembly that is structured to be selectively coupled to a mounting assembly body of the can bodymaker, wherein the moving assembly is structured to be selectively coupled to a ram drive assembly of the can bodymaker and moved with respect to the stationary assembly thereby, wherein the stationary assembly comprises: a stationary assembly base; a die pack coupled to the stationary assembly base, the die pack having a proximal end and a distal end; and a domer coupled to the stationary assembly base adjacent the distal end of the die pack, wherein the stationary assembly base includes a generally planar member that is sized and configured to substantially correspond to a recess defined in a first surface of the mounting assembly body, wherein the planar member includes a number of guide pin passages defined in, and extending through, the planar member, and wherein the number of guide pin passages comprises a plurality of guide pin passages disposed in a pattern structured to correspond to a plurality of guide pin passages defined in the recess and extending through the mounting assembly body.

2. The forming assembly of claim 1 , wherein the stationary assembly further comprises:
a redraw assembly coupled to the stationary assembly base adjacent the proximal end of the die pack; and
a ram guide assembly coupled to the stationary assembly base adjacent the redraw assembly generally opposite the die pack.

3. The forming assembly of claim 2 , wherein the ram guide assembly comprises:
a housing defining a passage; and
a number of bearing assemblies disposed in the housing, the number of bearing assemblies being structured to support a ram body of the moving assembly.

4. The forming assembly of claim 3 , wherein the ram guide assembly further comprises a seal pack assembly structured to substantially remove bearing fluid associated with the number of bearing assemblies from the ram body.

5. The forming assembly of claim 1 , wherein the generally planar member includes a number of upwardly depending, generally planar supports.

6. The forming assembly of claim 1 , wherein the die pack comprises a number of dies, each die having a generally toroid body having a central opening sized and configured to iron and otherwise form a blank positioned on a ram body of the moving assembly into a can body.

7. The forming assembly of claim 6 , wherein the die pack further includes a blank feed assembly structured to position the blank adjacent the proximal end of the die pack.

8. The forming assembly of claim 1 , wherein the domer comprises a domer body includes a domed surface having a vertex disposed facing, and generally aligned with, a forming passage of the die pack.

9. The forming assembly of claim 1 , wherein the moving assembly comprises a ram body.

10. The forming assembly of claim 9 , wherein the moving assembly further comprises a cam follower assembly coupled to a proximal end of the ram body, the cam follower assembly structured to cooperatively engage a cam of the ram drive assembly.

11. The forming assembly of claim 9 , wherein the ram body comprises a punch coupled to a distal end of the ram body.

12. The forming assembly of claim 11 , wherein:
the ram body defines a cavity structured to be selectively in fluid communication with a pressure assembly structured to generate a positive and/or negative fluid pressure;
the distal end of the ram body includes a passage in fluid communication with the cavity; and
the punch includes an axially extending passage.

13. A can bodymaker comprising: a mounting assembly having a mounting assembly body; a ram drive assembly; and a forming system comprising a number of forming assemblies, each forming assembly comprising: a stationary assembly; and a moving assembly movably coupled to the stationary assembly and selectively engaged with the ram drive assembly, wherein the stationary assembly and the moving assembly are a unified assembly that is selectively coupled to the mounting assembly body, wherein the mounting assembly body comprises a number of recesses defined in a first surface of the mounting assembly body; and the stationary assembly comprises: a stationary assembly base including a generally planar member that is sized and configured to substantially correspond to one recess of the number of recesses defined in the first surface of the mounting assembly body; a die pack coupled to the stationary assembly base, the die pack having a proximal end and a distal end; and a domer coupled to the stationary assembly base adjacent the distal end of the die pack, and wherein each recess of the number of recesses has a number of guide pin passages extending therefrom through the mounting assembly body; the planar member includes a number of guide pin passages defined in, and extending therethrough, and when the planar member of the stationary assembly base is disposed in the recess each guide pin passage of the number of guide pin passages defined in the planar member align with a corresponding guide pin passage defined in the mounting assembly body.

14. The can bodymaker of claim 13 , wherein:
the mounting assembly further includes a number of forming assembly positioning assemblies, each associated with a respective forming assembly of the forming system, and
each positioning assembly is structured to move an associated forming assembly among a first position, wherein the associated forming assembly is disengaged with the ram drive assembly, and a second position, wherein the associated forming assembly is engaged with the ram drive assembly.
