ABSTRACT:
A shearing arrangement for cutting moving bars in which two counter-rotating knife drums are rotatable in shear stands. These stands are spaced from each other and are located on a base plate. They are connected to each other above the knife drums by a disconnectable yoke. Both knife drums are mounted directly in the shear stands which are each of single-piece construction. The shear stands are inserted into the base plate and are connected to the base plate by quick-disconnect couplings. The quick-disconnect couplings between the shear stands and the base plate may be in the form of press rods, and the base plate may have lateral inclined guide surfaces or prisms for the shear stands. The knife drum is connected to its drive by an easily disengageable coupling which has a hydraulically shifted clutch sleeve.
