A portable, non-power operated cutting tool for cutting siding materials in a straight fashion without splintering or cracking. The cutting tool including a base with a cutting platform rotably connected to the base allowing the cutting platform to be set to cut siding at a range of angles from 0 to 180.

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).

An apparatus for improving the accuracy of machines which shear plate materials in general and sheet metals in particular. The apparatus comprises an indicator that is magnetically mounted to the shearing blade and extends downward toward the work table of the machine to give an indication of where the blade will pass through the metal.

A machine configured to form at least one whip from a length of cable according to some embodiments of the disclosure includes an input and an output defining a cable travel space being therebetween; a clamping assembly including a pad, and a first driving assembly configured to move the pad into the cable travel space and out of the cable travel space; and a cutting assembly including a cutting tool having at least one cutting edge, and a second driving assembly configured to move the cutting tool into the cable travel space and out of the cable travel space. In some embodiments, the machine further includes a saw assembly including a notching saw having a cutting edge configured to intersect the cable travel space, and a third driving assembly configured to drive the notching saw.

A control device according to some embodiments of the disclosure includes one or more motors directed by the control device to form whip(s) from a length of a cable by causing the cutting of the cable in accordance with specifications based at least in part on whip information. An interface communicates the whip information between the control device and a user device.

A drum cutting device, e.g., for shears adapted to cut flat metal products advancing along a direction substantially parallel to their direction of longitudinal extension, said device being adapted to cut said flat metal products transversely relative to their direction of advancement, wherein said device comprises at least one drum adapted to be rotated and diametrically delimited by a cylindrical surface containing a blade or knife which partially protrudes from said cylindrical surface, wherein said blade or knife is partially housed in a seat of said drum and extends longitudinally along a direction substantially parallel to the rotation axis of said drum, wherein said device comprises an adjustment wedge also housed at least partially in said seat of said drum, wherein the direction of extension of said wedge is substantially parallel to the rotation axis of said drum and the thickness of said wedge transversely to its direction of extension varies continuously along said direction of extension from a minimum thickness to a maximum thickness, wherein said wedge is positioned relative to said blade or knife so that the translation of said wedge parallel to its direction of extension in a first direction of translation results in a peripheral tangential translation of said blade or knife in a first direction of peripheral tangential translation, while the translation of said wedge in a second direction of translation opposite to the first one results in the peripheral tangential translation of said blade or knife in a second direction of peripheral tangential translation opposite to the first one, said device comprising translation means for the translation of said wedge in said two opposite directions of translation.

An apparatus for improving the accuracy of machines which shear plate materials in general and sheet metals in particular. The apparatus comprises an indicator that is magnetically mounted to the shearing blade and extends downward toward the work table of the machine to give an indication of where the blade will pass through the metal.

An auxiliary support device for a rolling-cut shear, including: a lower cutting table; a plurality of first hydraulic support cylinders, a plurality of support plates, a plurality of second hydraulic support cylinders shorter than the first hydraulic support cylinders, a slide plate, and a plurality of horizontal hydraulic cylinders. The lower cutting table includes a first front end including a first mounting groove, and a second mounting groove, and an inner plate. The bottom wall of the second mounting groove includes a plurality of first bolt holes and a plurality of first recesses. The inner plate is embedded in the second mounting groove through a plurality of bolts passing through the plurality of first bolt holes. The inner plate includes a plurality of second bolt holes and a plurality of second recesses. The plurality of support plates lean against the inner plate.

The present disclosure provides a reversible cutting tool to cut a material such as sheet metal on a press brake. The reversible cutting tool is further comprised of a handle portion to grip and move the cutting tool, wheels to allow the cutting tool to slide along the press brake, a blade portion to cut the material, and an adjustable cutting mechanism. The adjustable cutting mechanism allows the reversible cutting tool to pivot and cut the material in two different directions, and also allows the cutting tool to be set in a third storage position. In a preferred embodiment, the adjustable cutting mechanism is comprised of a channel on an underside of the cutting portion, the channel configured to receive a plunger, the plunger to slide between two opposed cutting positions and a storage position.
