Abstract

A connection rod coupling assembly includes a settable shape mounting second component having a lateral, primary axis and a bearing assembly including a bearing assembly body. The bearing assembly body includes a substantially cylindrical outer surface and a center axis. The bearing assembly body is coupled to the settable shape mounting second component in a non-aligned configuration. That is, the bearing assembly body center axis is offset from the settable shape mounting second component primary axis. Thus, the position of the bearing assembly body center axis is adjustable by repositioning the settable shape mounting second component relative to a settable shape mounting first component on a swing lever. The adjustment of the bearing assembly body, in turn, adjusts the range of the ram assembly and the ram assembly body.

First claim

What is claimed is:

1. A ram assembly for a bodymaker, said bodymaker including a reciprocating swing lever, said swing lever including a pivoting first end and a moving second end, said swing lever second end including a settable shape mounting first component, said ram assembly comprising:
an elongated ram body including a distal end;
a carriage, said carriage including a rotational coupling and a ram body mounting;
said ram body fixed to said carriage ram body mounting;
a connection rod, said connection rod including a first end and a second end;
said connection rod first end including a first rotational coupling;
said connection rod second end including a second rotational coupling;
said connection rod second end second rotational coupling is rotatably coupled to said carriage rotational coupling;
a connection rod coupling assembly, said connection rod coupling assembly structured to adjustably couple said connection rod first end first rotational coupling to said swing lever second;
wherein said connection rod coupling assembly includes a settable shape mounting second component and a bearing assembly; said settable shape mounting second component has a lateral, primary axis; said bearing assembly includes a bearing assembly body, said bearing assembly body includes a substantially cylindrical outer surface and a center axis; and said bearing assembly body center axis is offset relative to the settable shape mounting second component primary axis;
wherein said swing lever second end settable shape mounting first component includes two settable shape cavities, said settable shape mounting second component includes a first lug and a second lug, and each settable shape mounting lug is shaped to correspond to an associated settable shape cavity;
wherein said settable shape mounting second component includes a bearing mounting, said bearing mounting includes a generally cylindrical outer surface, said bearing mounting extends between said settable shape mounting lugs, and said bearing assembly body is coupled to said bearing mounting; and
wherein said ram assembly body distal end is disposed a selected distance from said swing lever second end.

2. The ram assembly of claim 1 wherein said settable shape mounting lugs have a mirrored shape.

3. The ram assembly of claim 1 wherein said settable shape mounting lugs are planar.

4. The ram assembly of claim 3 wherein said settable shape mounting lugs are regular convex polygonal lugs.

5. The ram assembly of claim 3 wherein said settable shape mounting lugs are octagonal lugs.

6. The ram assembly of claim 1 wherein:
said settable shape mounting lugs are planar;
said settable shape mounting second component bearing mounting includes a generally cylindrical first portion and a generally cylindrical second portion;
said settable shape mounting second component bearing mounting first portion extending from, and generally perpendicular to the plane of, the first lug; and
said settable shape mounting second component bearing mounting second portion extending from, and generally perpendicular to the plane of, the second lug.

7. The ram assembly of claim 6 wherein:
said first lug and said settable shape mounting second component bearing mounting first portion define a passage;
said settable shape mounting second component bearing mounting second portion defines a threaded bore;
said settable shape mounting second component includes a threaded fastener;
said settable shape mounting lugs are coupled by said settable shape mounting second component fastener; and
said bearing assembly body is coupled to said settable shape mounting second component bearing mounting.

8. A bodymaker comprising:
a reciprocating swing lever including a pivoting first end and a moving second end;
said swing lever second end including a settable shape mounting first component;
a ram assembly including an elongated ram assembly body, a carriage, and a connection rod;
said ram assembly body including a distal end;
said carriage including a rotational coupling and a ram assembly body mounting;
said ram assembly body is fixed to said carriage ram assembly body mounting;
said connection rod includes a first end and a second end;
said connection rod first end includes a first rotational coupling;
said connection rod second end includes a second rotational coupling;
said connection rod second end second rotational coupling rotatably coupled to said carriage rotational coupling;
a connection rod coupling assembly, said connection rod coupling assembly adjustably coupling said connection rod first end first rotational coupling to said swing lever second end;
wherein said connection rod coupling assembly includes a settable shape mounting second component and a bearing assembly; said settable shape mounting second component has a lateral, primary axis; said bearing assembly includes a bearing assembly body, said bearing assembly body includes a substantially cylindrical outer surface and a center axis; and said bearing assembly body center axis is offset relative to the settable shape mounting second component primary axis;
wherein said swing lever second end settable shape mounting first component includes two settable shape cavities, said settable shape mounting second component includes a first lug and a second lug, and each settable shape mounting lug is shaped to correspond to an associated settable shape cavity;
wherein said settable shape mounting second component includes a bearing mounting, said bearing mounting includes a generally cylindrical outer surface, said bearing mounting extends between said settable shape mounting lugs, and said bearing assembly body is coupled to said bearing mounting; and
wherein said ram assembly body distal end is disposed a selected distance from said swing lever second end.
