Abstract
A knockout tool for forming a hole in a material, such as a sheet of metal, is provided. The knockout tool includes a body, a die mounted on a first end of the body, and a punch mounted on the second end of the body. A die plug is coupled to the first end of the body by a drive component, and a thrust bearing is positioned between the die and die plug such that at least a portion of the thrust bearing can rotate between the die and die plug. When the drive component is rotated in a first direction, the die plug and thrust bearing convert rotational movement of the drive component into linear movement and move the die into engagement with the punch.
Claims20
A knockout tool, comprising:
- a longitudinal axis;
- a body, comprising:
- a first end centered on the longitudinal axis;
- and
- a second end opposite the first end and aligned with the first end along the longitudinal axis;
- a die plug coupled to the first end of the body;
- a die coupled to the die plug;
- a thrust bearing positioned between the die plug and the die, wherein at least a portion of the thrust bearing can rotate between the die and die plug with respect to the longitudinal axis;
- a punch coupled to the second end of the body, the punch comprising a cutting end configured to be received in the die;
- and
- a drive component extending through the first end of the body and received in the die plug, the drive component configured to rotate with respect to the longitudinal axis;
- and
- wherein when the drive component is rotated in a first direction, the die plug and thrust bearing convert rotational movement of the drive component into linear movement and move the die into engagement with the punch along the longitudinal axis.

A hole forming tool, comprising:
- a longitudinal axis;
- a body, comprising:
- a first end centered on the longitudinal axis;
- and
- a second end opposite the first end and aligned with the first end along the longitudinal axis;
- a punch coupled to the second end of the body;
- a die coupled to the first end of the body and centered on the longitudinal axis, the die comprising:
- a first side facing away from the first end of the body and configured to receive the punch;
- and
- a second side opposite the first side along the longitudinal axis;
- a die plug coupled to the first end of the body;
- a thrust bearing positioned between the die plug and the second side of the die, wherein at least a portion of the thrust bearing can rotate between the die and die plug with respect to the longitudinal axis;
- a drive component extending through the first end of the body and received in the die plug, the drive component configured to rotate with respect to the longitudinal axis;
- and
- wherein, when the drive component is rotated in a first direction, the die plug and thrust bearing convert rotational movement of the drive component into linear movement such that the drive component moves axially along the longitudinal axis and moves the die into engagement with the punch.

A tool, comprising:
- a body, comprising:
- a first end centered on a longitudinal axis;
- and
- a second end opposite the first end and aligned with the first end along the longitudinal axis;
- a die plug positioned adjacent to the first end of the body;
- a die coupled to the die plug such that the die plug is positioned between the die and the first end of the body along the longitudinal axis;
- a thrust bearing positioned between the die plug and the die, wherein at least a portion of the thrust bearing can rotate between the die and die plug with respect to the longitudinal axis;
- a drive component extending through the first end of the body and received in the die plug such that the die plug is coupled to the first end of the body, the drive component configured to rotate with respect to the longitudinal axis;
- and
- a punch coupled to the second end of the body, the punch comprising a cutting end configured to be received in the die;
- and
- wherein, when the drive component is rotated in a first direction, the die plug and thrust bearing convert rotational movement of the drive component into linear movement such that the drive component moves the die plug, thrust bearing, and die axially along the longitudinal axis towards the punch.
