Abstract
A variable rake shear comprises a housing (8), a first blade (1) mounted in a first blade mounting (4), a second blade (2) mounted in a second blade mounting (3); and a control device (5) to control movement of one blade mounting to shear the material. Each blade mounting is movable in at least one dimension relative to the housing. One blade is an active blade (1) and the other blade is a passive blade (2). A rake adjustment mechanism (6a, 6b) for at least one of the mountings (3, 4) and the mounting (4) for the active blade (1) has a torque tube linkage mechanism (10, 11, 12).
Claims9
A method of operating a variable rake shear to shear material, the method comprising;
- mounting a first blade in a first blade mounting, mounting a second blade in a second blade mounting, wherein each blade mounting is movable in at least one dimension relative to the housing to move the blades toward and past each other for shearing;
- applying a rake angle to one of the first and second blade mountings;
- wherein one blade is an active blade and the other blade is a passive blade;
- connecting the first blade mounting of the active blade to a torque tube linkage mechanism configured for;
- and controlling movement of the first blade mounting of the active blade to shear the material.
