Wedge cutting
In manufacturing technology, wedge cutting refers to the division ( pressing apart) of a material using one or two wedge-shaped cutting edges. This procedure is standardized in DIN 8588.
Possible types
Wedge blade on anvil
In the variant of knife cutting , the material rests on a suitably hard base and is pushed apart by moving a single wedge-shaped cutting edge.
An example of use is cutting through self-adhesive labels on their backing paper, which should be damaged as little as possible; The aim is to make it easier to later lift the labels at the edge from the arched, typically protruding carrier. A cookie cutter cuts a piece out of a thin layer of soft dough. Typically, holes are punched in thin, soft materials, such as a leather belt or a truck tarpaulin, with punch pliers or punches .
Wedge edge on wedge edge
When biting, on the other hand, the workpiece is located between two opposing wedge-shaped cutting edges that are moved towards each other and thereby push the material apart.
Tools that use this principle are side cutters , monier pliers , nail clippers , lever end cutters and bolt cutters .
