Unipunch toolings offers sheet punching systems that are of press tooling to pierce sheets. Pierce of holes and cutting of corners and edges is achieved. Re-arranging the tools can alter the position of the holes. These systems operate on the principle that each unit [frame] carries a die and punch, which is interchangeable for size. Each unit is intended to punch one hole. Several units are employed together to punch multiple holes. The position of the units is shifted to achieve different patterns of punching. The edge and corner cutting units are designated as notching units. The tools require to be used in a press or press brake, which will give the power to cut. The units have their own stripping arrangement. Multiple punching of holes is achieved on account of common die and shut heights. The same tools are repeatedly used to punch different components.
