    摘要: A punching die includes a punch body, a punch driver secured to the punch body, and a punch head provided for an upper portion of the punch driver. The punch head is struck by a striker. The punch die further includes a punch guide fitted to the punch body, a stripper plate disposed at a lower portion of the punch guide, a stripping spring interposed between the punch guide and a flange portion of the punch driver, and a elastically deformable damping member interposed between an upper surface of the punch driver and a lower surface of the punch head.

    摘要: A stripper device for a punching tool comprises: a gas cylinder (5) filled with a gas (7) having a cylinder head (27) and a cylinder end (17) attached to a lower end of the cylinder head airtightly; and a piston (9) having a punch head (11) and a piston rod (15); an axial movement restricting member (13, 201) for restricting an axial movement of the piston in the gas cylinder filled with the gas; and a rotational movement restricting members (31; 205, 203) for restricting a rotational movement of the piston in the cylinder body. A stripping force of the stripper device can be obtained by a resilient force generated whenever the gas is compressed by the piston within the gas cylinder for each punching operation. The punch assembly enables plate material of various thicknesses to be punched out without generating stripping miss. Further, when the stripper device is assembled with a punch body (19) as a punch assembly, the assembly length of the punch assembly can be adjusted finely by a stroke adjusting mechanism composed of a locating pin (41), locating holes (43) and thread engagement of the piston with the punch body.

    摘要: A punching tool for a press, includes: a punch guide (19) having a stripper plate (33) at a lower end thereof; a punch body (25) formed with a blade portion (27) at a lower end thereof and disposed within the punch guide movably up and down; a punch driver (37) having a piston rod (43) formed integral therewith and fixed to the punch body (25); a gas spring section (15) having a gas cylinder (45), the piston rod of the punch driver (37) being passed through the gas cylinder movably up and down, and a high pressure gas being filled in the gas cylinder to urge the punch driver (37) upward; and an annular elastic member (61) interposed between an upper surface of the punch guide (19) and a lower surface of the gas cylinder (45) of the gas spring section (15) to absorb shock generated when the stripper plate (33) attached to the punch guide (19) collides against work (W) during punching processing. The punching tool can reduce noise generated during punching processing and further to prevent a punching mark (scar) from being formed on the surface of the punched work.

    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.
