A turret punch machine is disclosed having upper and lower turrets each equipped to carry a plurality of tools. The turrets carry a plurality of modules projecting from a central turret section in spoke-like fashion. The modules on the upper turret are each adapted to carry one or more punching tool assemblies and the modules on the lower turret are each adapted to carry one or more die tools. The modules are attached to and rotate with the turret by interfitting connections adjacent the modules' inner peripheries, the modules being easily detachable from the turrets to allow quick tool and/or module change.

Modular turret punch press

A punching device includes a fixed frame adapted to support punch means in alignment with a ram. An assembly of the punch, a guide and stripping sleeve and a stripping spring is removable as a unit and such assembly includes means by which such assembly is retained together, especially during handling away from the frame of the punching device. To this end, the punch has a radial opening, such as a circumferential groove, in which there is disposed a friction member, such as of plastic, which has an interference fit with the interior of the stripping sleeve.

Punching device with punch retainer

Tooling for use in a punching device, the tooling being a punch and stripping guide assembly, comprises a stripper sleeve guiding a punch having a threaded end encircled by a stripping spring which is preloaded by a threaded punch head secured thereto, the threaded end and the threaded head having hexagonal axial openings in which a locking rod of corresponding cross-section is disposed.
