摘要： In a punching processing method, a punch chip (29) having a roller shape is arranged in a punch chip holder (27) rotatable around the vertical axis and can be rotated around the horizontal axis. A die chip (47) having a roller shape is arranged in a die chip holder (65) rotatable around the vertical axis and can be rotated around the horizontal axis. Punching processing of a work is performed, in cooperation with the punch chip and the die chip, by moving the work (w) in the horizontal direction in a state in which the work is held between the punch chip and the die chip. Further, a roll forming die used in this punching processing method is also proposed. Accordingly, it is possible to perform various kinds of punching processings for a short time without causing any seam and easily perform processings of a circle and a curve in addition to processing of only a straight line.

摘要： A die unit for performing punching operations in cooperation with a punch unit is disclosed. The die unit includes a die body (3) formed with a die hole (5) extending in an axial direction for receiving a cutting edge of the punch body (17) , and with an upper surface portion (7) extending in a plane normal to the axial direction. The die unit also includes a projecting portion (11) formed along the perimeter of the die hole (5) on the upper surface portion (7) of said die body (3). With this die unit, punching operations can be performed on a workpiece without producing s burr that projects downwardly below the lower surface of the workpiece. Thus burr removing operations are dispensed with after the punching operations.

摘要： In a punching tool having a punch body (23), a punch driver (33) integral with the punch body, a punch head (45) disposed over the punch driver and struck by a striker (59), a punch guide (15) for guiding the punch body, a stripper plate (17) disposed under the punch guide, and a stripping spring (51) interposed between the punch guide (15) and the punch driver (33), the punching die further includes a first damping member (39) interposed between the punch guide (15) and the punch driver (33) so as to be elastically deformable within a predetermined deflection value. Owing to the presence of the first damping member (39), it is possible to reduce noise generated when the punch body (23) is returned upward by a strong urging force of the stripping spring (51) after work has been punched, thus preventing overall noise generated during punching processing.
