Adjustable domer door for can bodymaker

A domer arrangement for use in supporting a domer die in a can bodymaker, the domer arrangement comprising:

• a subframe structured to be coupled to a frame of the can forming machine, and
• a domer assembly comprising:
• a domer door comprising a first end and a second end opposite the first end, the domer door being structured to have the domer die coupled thereto between the first end and the second end;
• a first spacer member having a first face and a second face opposite and spaced a first thickness from the first face, the first face of the first spacer member engaged with the subframe and the second face of the first spacer member engaged with the domer door at or about the first end of the domer door;
• a second spacer member having a first face and a second face opposite and spaced a second thickness from the first face, the first face of the second spacer member engaged with the domer door at or about the second end of the domer door and the second face engaged with the subframe;
• and
• a fastening arrangement rigidly coupling the domer door to the subframe such that the domer door is secured at a predetermined positioning relative to the subframe dependent on the thickness of each of the first and second spacer members,
• wherein the fastening arrangement comprises:
• a first swing bolt having a first end and a second end opposite the first end, the first end being pivotably coupled to the subframe and the second end having a threaded portion extending therefrom toward the first end;
• a second swing bolt having a first end and a second end opposite the first end, the first end being pivotably coupled to the subframe and the second end having a threaded portion extending therefrom toward the first end;
• a first threaded nut threadingly engaged with the threaded portion of the first swing bolt;
• and
• a second threaded nut threadingly engaged with the threaded portion of the second swing bolt, and
• wherein when the first threaded nut and the second threaded nut are each tightened on the respective threaded portions of the first and second swing bolts, the domer door is secured at the predetermined positioning dependent on the thickness of each of the first and second spacer members.

A can forming machine comprising:

• a frame;
• an operating mechanism coupled to the frame and structured to reciprocally move a ram body between a first retracted position and a second extended position;
• a ram body comprising an elongated body with a longitudinal axis and a distal end;
• a punch disposed at the distal end of the ram body;
• a die assembly coupled to the frame and having at least one die with an opening therein and a longitudinal axis;
• the punch positioned to move generally horizontally through the die opening with said ram body longitudinal axis and said die assembly longitudinal axes being substantially aligned;
• and
• a domer arrangement comprising:
• a subframe structured to be coupled to a frame of the can forming machine;
• a domer assembly comprising:
• a domer door comprising a first end and a second end opposite the first end, the domer door being structured to have the domer die coupled thereto between the first end and the second end;
• a first spacer member having a first face and a second face opposite and spaced a first thickness from the first face, the first face of the first spacer member engaged with the subframe and the second face of the first spacer member engaged with the domer door at or about the first end of the domer door;
• a second spacer member having a first face and a second face opposite and spaced a second thickness from the first face, the first face of the second spacer member engaged with the domer door at or about the second end of the domer door and the second face engaged with the subframe;
• and
• a fastening arrangement rigidly coupling the domer door to the subframe such that the domer door is secured at a predetermined positioning relative to the subframe dependent on the thickness of each of the first and second spacer members;
• and
• a hinge arrangement, wherein the domer door is pivotably and slidably coupled to the subframe at or about the first end thereof via the hinge arrangement,
• wherein:
• the hinge arrangement comprises an upper hinge pin and a lower hinge pin axially aligned with, and spaced from the upper hinge pin;
• the first end of the domer door comprises an upper cylindrical recess extending downward from a top surface of the domer door and a lower cylindrical recess extending upward from a bottom surface of the domer door axially aligned with the upper cylindrical recess;
• a lower portion of the upper hinge pin is positioned within the upper cylindrical recess of the first end of the domer door and an upper portion of the upper hinge pin is positioned within an elongated slot defined in the subframe;
• and
• an upper portion of the lower hinge pin is positioned within the lower cylindrical recess of the first end of the domer door and a lower portion of the lower hinge pin is positioned within another elongated slot defined in the subframe.
