A device by which thin-walled materials, such as labels and flat lids for containers, can be punched in micro or small quantities. The device includes a band steel cutting edge (11) that is elastically mounted in the punching direction. The matrix is likewise elastically held on the matrix plate perpendicular to the punching direction by virtue of a matrix seat (33) fastened to the region in the matrix plate (27) that is adjacent to the opening (29). On the matrix seat, an elastically deformable intermediate plate (47) is placed, and the matrix (55) is placed on the intermediate plate.

An example of a blanking die includes a blanking apparatus configured to form a series of at least two metallic blanks from sheet metal, and an ejection apparatus configured to eject a first one of the series of the metallic blanks out of the blanking die in a predetermined direction and a second one of the series of the metallic blanks out of the blanking die in said predetermined direction.

A method punches out a damper from a damper material set on a punching stage with use of a hollow punch so that the punched damper is positioned within a hollow inside of the punch while vibrating a member composing the punching stage on which the damper material is set at the high frequency. The damper material includes a viscoelastic body layer and the constraint layer laminated on the viscoelastic body layer and the viscoelastic body layer includes an attaching surface through which the damper material is detachably attached on the liner.

In a cutting die having a cutting chip, applied to a punch press, and cutting a work in collaboration with a cutting punch, a resistance member for guiding swarf generated during cutting of the work through the cutting chip and dividing it by giving resistance to it is provided around a scrap discharge hole so that the divided swarf does not remain in the scrap discharge hole but is discharged to an outside so as to prevent clogging by scrap.
