ABSTRACT:
A DIN rail cutter and punching apparatus for cutting a DIN rail to a selected length and for punching at least one mounting slot therethrough at a desired angular orientation comprises a shear for cutting the DIN rail and a punch and die set which is operatively coupled for operation in unison with the shear. The DIN rail cutter comprises a shear for cutting the DIN rail and is arranged for removably receiving a cutting die for accommodating any of a plurality of cutting dies for cutting different shapes of DIN rail. A rotating punch and die set for punching a DIN rail at any of a plurality of angular orientations comprises a punch mounting block; a punch rotatably mounted in the punch mounting block; a die mounting block and a die rotatably mounted in the die mounting block; the punch mounting block and the die mounting block are mounted for relative movement so as to advance and retract the punch into an out of engagement with the die. An interlocking member releasably interlocks with the die for preventing rotation thereof. A release arrangement releases the interlocking member in response to advancement of the punch into engagement with the die such that rotation of the die can only be achieved with the punch in engagement therewith to thereby positively maintain alignment between the punch and the die without regard for the angular orientation of the punch and die relative to a workpiece.
