The present invention makes it possible to obtain a fine finish along a trim line in a plate material while preventing scoring between a floating cutter and a main trimming press upper. A floating cutter unit is provided with: a floating cutter for cutting scrap from a plate-shaped material, said floating cutter being attached to and used in a trimming press processing device that cuts scrap from a plate material along a trim line Tr and that additionally cuts scrap along a scrap cut line Sc; a holder set for holding the floating cutter so as to be movable in the direction of an axial center O; a spring that is brought into contact with the tail end surface of the floating cutter and that applies reaction force to the floating cutter; and a pair of cutters that are attached to the holder set and positioned on both sides of the floating cutter along the trim line Tr.

Floating cutter unit and trimming press processing device

The present invention increases the positional accuracy of a floating cutter unit with respect to a press upper die for main trimming. A floating cutter unit is provided with: a floating cutter for cutting scrap from a plate-shaped material, said floating cutter being attached to and used in a trimming press processing device that cuts scrap from a plate-shaped material along a trim line Tr and that additionally cuts scrap along a scrap cut line Sc; a spring that is brought into contact with the tail end surface of the floating cutter and with a holder set for holding the floating cutter so as to be movable in the direction of an axial center O, and that applies reaction force to the floating cutter; and a guide member that is attached to the holder set, brought into contact with the floating cutter, and used to guide movement in the direction of the axial center O.

A trimming press working apparatusincludes a trimming meansfor cutting a plate materialalong a trimming linewhich divides a product portionfrom a non-product portionin the plate material; a scrap cutting meansfor cutting the non-product portionalong scrap severing lineseach intersecting the trimming lineto make the non-product portioninto a plurality of scrap pieces; and a padfor pressurizing and restraining the product portionof the plate material
