Abstract

A toolpack for a can bodymaker with a vertically oriented, reciprocating, elongated ram assembly is provided. The toolpack includes a tool pack housing assembly, a number of die spacers, a number of dies, and a compression device. The tool pack housing assembly defines a passage and includes an inner surface, an upper sidewall, a lower sidewall, a first lateral sidewall, a second lateral sidewall, a rear sidewall, and a door. The tool pack housing assembly passage extends generally vertically. Each die spacer structured to support a die and defining a central passage. Each die including a body defining a central passage. The die spacers and dies are disposed in said tool pack housing assembly. The compression device is disposed at said tool pack housing assembly lower sidewall and is structured to axially bias said number of die spacers.

First claim

What is claimed is:

1. A vertically oriented bodymaker tool pack comprising:
a tool pack housing assembly defining a passage and including an inner surface, an upper sidewall, a lower sidewall, a first lateral sidewall, a second lateral sidewall, a rear sidewall, and a door;
said tool pack housing assembly passage extending generally vertically;
a number of die spacers, each die spacer structured to support a die and defining a central passage;
a number of dies, each die including a body defining a central passage;
a number of die spacers and a number of dies disposed in said tool pack housing assembly;
a compression device disposed at said tool pack housing assembly lower sidewall, said compression device structured to axially bias said number of die spacers;
whereby said number of dies spacers and said number of dies are biased upwardly;
said tool pack housing assembly first lateral sidewall and said tool pack housing assembly second lateral sidewall include a front surface;
said door includes an inner surface;
said door structured to move between a first, open position, wherein said door provides access to said tool pack housing assembly passage, and a second, closed position, wherein said door inner surface is disposed immediately adjacent said first lateral sidewall front surface and said tool pack housing assembly second lateral sidewall front surface;
said door inner surface including a number of resilient bumpers, each said bumper aligned with one of said dies, each said bumper having a thickness sufficient so that, when said door is in said second position, each said bumper contacts one of said dies; and
wherein, when said door is in said second position, each said bumper contacts at least one of said dies and biases said die toward said tool pack housing assembly rear sidewall.

2. The bodymaker tool pack of claim 1 wherein:
each said die body including a generally circular outer surface;
each said bumper including a distal surface; and
wherein each said bumper distal surface is concave and has a curvature corresponding to said die body outer surface.

3. The bodymaker tool pack of claim 1 wherein:
said door includes a latch assembly;
said latch assembly including a latch base and a latch handle; and
said latch handle coupled to said first lateral sidewall, said latch handle including a cam member, said latch handle structured to move between an open, first position, wherein said latch handle does not engage said latch base, and a closed, second position, wherein said latch handle cam member engages said latch base.
