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.

A splitting apparatus includes: a lower mold configured to allow placement of a plate material on the lower mold and arranged on a first side with respect to a split target line of the plate material; an upper blade configured to be raised or lowered with respect to the lower mold; and a support member arranged on a second side with respect to the split target line of the plate material. The splitting apparatus is configured that, in a case where the upper blade is lowered with respect to the lower mold in a state where the plate material is supported by the lower mold and the support member, a cut is formed on the split target line of the plate material by the upper blade, a crack is formed in conjunction with formation of the cut, and the plate material is split along the split target line.

A sheet cutting and bending apparatus for cutting a wavy sheet and forming trapezoidal notches required for installation includes a base, two cutters at an end of the base, and a force applying mechanism for driving the two cutters. A knife of the cutters has no handle but just has a curved force receiving edge at the rear edge. The force applying mechanism has two rocker aims driven by a rocker rod and a force applying rod bridging between the two rocker arms for abutting a force receiving edge of the knife to produce a shear force and pushing the knife efficiently to cut two incisions at an edge of the sheet. In addition, a bending mechanism is linked with the force applying mechanism and provided for flipping a plate between the two incisions inwardly to form trapezoidal notches required for installation at the edge of the sheet.

Devices for cutting an aerial obstacle are provided. Such devices may comprise a mounting frame; an anchor point for attachment to a hoist; a cutter mounted to the mounting frame, the cutter having opposing cutting blades for engaging and cutting the obstacle when positioned therebetween; a power supply mounted to the mounting frame, the power supply providing power to the cutter for actuating the cutting blades; and a guiding frame extending from the mounting frame, the guiding frame providing an inner guiding surface for directing the obstacle to a position between the opposing cutting blades of the cutter. Methods of using such devices for cutting aerial obstacles, such as cables, beams and/or branches, are also provided herein.

An apparatus for cutting a profile, including: a cutter configured to make cuts on the profile having a first surface and a second surface, and having at least one rib on the first surface, wherein the cuts are made on the first surface of the profile; a first drive unit to drive the cutter forward and backward to and from the first surface of the profile; and a second drive unit to drive the cutter up and down along the first surface of the profile.

Cutting equipment for a metal strip includes a frame, and a feeding device, a fetching device and a cutting device. The cutting device includes a first pressing mechanism, a support platform, and a vacuum generating device, the first pressing mechanism is configured to press the strip, the support platform is provided with a through hole connected to the vacuum generating device. The vacuum generating device is configured to position the strip on the support platform, the first pressing mechanism and the support platform are movable up and down respectively to form a height difference between a first strip section located on the first pressing mechanism and a second strip section located on the support platform for cutting. The equipment can automatically cut metal strips, and is more reliable in the cutting operation and has a high cutting success rate.

A method and apparatus for forming and trimming an associated corner region formed from a flat plate. A die and a knife assembly includes a die that is movable in opposed reciprocating directions within a first plane. A support assembly for the corner region holds the corner region at oblique angle with respect to the plane.
