ABSTRACT:
An apparatus for punching of an angular steel profile comprises a feed conveyor and a discharge conveyor for the angular steel profile, a rigid frame portion, two punch carriages and at least one punch carriage positioning motor for moving the punch carriages mounted on the frame portion and a servomechanism for positioning at least one of the punch carriages according to the tolerances, particularly the angular tolerances, of the angular steel profile to be worked. The servomechanism for positioning the punch carriage has a compressively loaded roller sensor contacting on a reference surface of the angular steel profile and a signaling member operated by the roller sensor. The feed conveyor, the discharge conveyor and the punches are equipped for feeding and working a vertically oriented V-shaped angular steel profile. The angular steel profile to be worked is movable by the frame portion and the punch carriages with the help of a clamp member oriented vertically, traveling horizontally and gripping the angular steel profile in a channel through the working zone. The clamp member passes through a clamp slot connected to the working zone. An outer surface of the angular steel profile not to be worked by the punch is used as a reference surface.
