A bending and forming device is disclosed having an operating head and its holder features a holder which is a multi part structure including a saddle for seating the head and a releasably connected gib, a limited portion of which is adapted to releasably bear on and hold the head to and for a rocking or rotative movement thereof on its seat. The head is preferably a cylindrical body having a groove the length of its outer peripheral surface, the bounding walls of which groove determine the operation to which the head may be applied. The retention device is connected to the saddle so as to enable an easy adjustment of its position to accommodate variation in the dimension of the operating head or wear of the related parts. In preferred embodiments the saddle affords a concentrated load bearing surface for the head provided by relatively narrow, adjacent and relatively spaced, longitudinally extended, strip-like bearings. Preferred embodiments also feature slip interfit parts of the saddle on the head which are used to limit and control the rotative or rocking movements of the head in the course of its operation.

Bending and forming apparatus comprises an anvil adapted for use in a press in conjunction with a die connected to an opposed portion of the press, to form and bend material interposed therebetween as the press closes during its cyclic operation. The anvil includes a plurality of elements each of which is normally fixed to form an extension of another by an embodied locking device. In its extended condition the anvil is a rigid unitized structure of substantially fixed length. The locking device is constructed and arranged to release to provide the elements as hard tooling of reduced length as bending and forming of the material worked thereby proceeds, to set the bent and formed configuration of the material worked. A trigger device is included for triggering the release of the locking device to provide for reduction in length of the anvil. The bending and forming apparatus provides hard tooling in both its original condition and when reduced in length.
