Abstract
A multiple segment steel rule die is provided comprising a base plate having one or more channels formed therein, cutting rules secured in the channels, scoring rules secured in the channels, and at least one counter plate for cooperating with the base plate. The counter plate has slots formed therein for receiving the scoring rules. The base plate and the at least one counter plate are removably fixed to opposite heads of a press to facilitate operation of the steel rule die. The multiple segment steel rule die produces at least two blanks from stock material during a pressing operation.
Claims22
A multiple segment steel rule die comprising:
- a base plate having one or more channels formed therein;
- cutting rules secured in the channels;
- scoring rules secured in the channels;
- and
- at least one counter plate for cooperating with the base plate, the counter plate having slots formed therein for receiving the scoring rules,
- wherein the base plate and the at least one counter plate are removably fixed to opposite heads of a press to facilitate operation of the steel rule die, the multiple segment steel rule die producing at least one blank from stock material during a pressing operation.
A multiple segment steel rule die comprising:
- a plate for mounting on a first surface of a press, the plate having one or more narrow channels formed therein;
- steel cutting rules secured in some of the narrow channels, the steel cutting rules substantially defining perimeters of blanks to be cut by the steel cutting rules;
- steel scoring rules secured in the remaining channels, the steel scoring rules residing substantially inside the perimeters;
- a steel backing plate for mounting on a second opposing surface of the press;
- and
- a sectional multiple segment steel counter plate for cooperating with the plate and for mounting on the steel backing plate, the sectional multiple segment steel counter plate having slots formed therein for receiving the steel scoring rules during a pressing operation, the sectional multiple segment steel counter plate having at least two separate pieces.
A press having opposing first and second surfaces, the press comprising:
- a multiple segment steel rule die formed from a base plate having a plurality channels formed therein, the base plate being removably mounted on the first surface;
- steel cutting rules secured in the channels;
- steel scoring rules secured in the channels;
- a steel backing plate removably mounted on the second surface;
- and
- at least one steel counter plate attached to the steel backing plate for cooperating with the multiple segment steel rule die, the steel counter plate having slots formed therein for receiving the steel scoring rules.
