Abstract
A device for changing a blade on shears, in particular for a rolled band, and to such shears in which a blade can be fixed to at least one blade support automatically by a tie bar pretensioned by a force accumulator. The device includes at least one adjusting element which can be actuated in order to release the blade from the blade support such that the tie rod is moved in an axial direction against the tie rod pretension. The adjusting element can be arranged on an outer face of the blade support or outside of the blade support.
Claims19
A device for changing at least one blade on shears, the blade being automatically securable on a blade carrier by a tie rod that is pretensioned by a force accumulator, the device comprising an adjusting member which, for releasing the blade from the blade carrier, is actuable so as to move the tie rod in an axial direction in a manner opposed to the pretensioning, wherein the adjusting member is arrangable on an outer side of the blade carrier or outside the blade carrier, wherein the adjusting member includes a hydraulic cylinder and an actuating pin that is movable in a direction of a longitudinal axis of the tie rod and can be brought into contact bearing with an end side of the tie rod either directly or indirectly, wherein the actuating pin is connected to a piston of the hydraulic cylinder, arranged to move the actuating pin.
