Compound angle cutting edge and method of using same

Номер: US0004002092A1
Автор: Smith; Billy R., Smith; Francis Moses

A novel compound angle cutting edge configuration on a die rule, slitter blade, hollow punches, shearing blades, etc. provides cleaner cuts on stock material with less tonnage, improved cutting and cleaner cuts. The die rule cutting edge includes a plurality of side by side notches on only one side of the cutting edge defining a plurality of equally spaced piercing points. A primary cutting edge extends from each piercing point substantially to a next adjacent piercing point and forms a compound angle with an imaginary line through the tips of the piercing points of between about one and fifteen degrees. In use, the cutting edges are axially pressed through stock material to cut blanks of predetermined configuration. The cutting action consists of the piercing points penetrating the material and then the primary cutting edges slicing the stock material from one penetration point, substantially linearly and unidirectionally, to the next adjacent penetration point.
