Abstract
A clamp piece is provided for interconnecting an inner grid to an outer frame of a frame assembly of a lower blanking tool of a carton die cutting machine. The clamp piece includes a plate member having inner and outer faces and a cavity formed therein for receiving a portion of the bar that makes up the inner grid. A bore extends between the inner face and the outer face of the plate member along an axis at an acute angle to the outer face. A screw extends through the bore and into the outer frame to interconnect the clamp piece to the outer frame. A clamping structure is positioned within the cavity and is movable between a clamping position for retaining the portion of the bar in the cavity of the plate member and a release position.
Claims25
A clamp device for attaching a bar of an inner grid to an outer frame for a lower blanking tool of a carton die cutting machine, comprising:
- a plate member defining a vertically extending inner face, an opposite vertically extending outer face, a horizontally extending upper face having a cavity formed therein for receiving a portion of the bar, and a bore extending between the inner face and the outer face along an axis at an acute angle to the outer face;
- and
- a wedge member pivotably disposed within the cavity and movable between a clamping position for retaining the portion of the bar in the cavity of the plate member and a release position, the wedge member including a clamping surface engageable with the bar with the wedge member in the clamping position.
A clamp device for attaching a bar of an inner grid to an outer frame for a lower blanking tool of a carton die cutting machine, comprising:
- a plate member defining inner and outer faces, the plate member having a cavity formed therein for receiving a portion of the bar and a bore extending between the inner face and the outer face along an axis at an acute angle to the outer face;
- and
- a clamping structure position within the cavity and movable between a clamping position for retaining the portion of the bar in the cavity of the plate member and a release position.
A frame assembly for a lower blanking tool of a carton die cutting machine, comprising:
- a rigid outer frame;
- an inner grid comprised of a plurality of lengthwise and crosswise extending bars;
- and
- a plurality of clamps attaching the bars to the outer frame, each clamp including:
- a plate member defining a vertically extending inner face, an opposite vertically extending outer face and, a horizontally extending upper face having a cavity formed therein for receiving a portion of the bar;
- and
- a wedge member pivotably disposed within the cavity and movable between a clamping position for retaining the portion of the bar in the cavity of the plate member and a release position.
