A cutting device capable of efficiently cutting an object with a simple configuration includes a grasp unit including a first grasper and a second grasper movable in an opening and closing directions to grasp the object, a cutting unit disposed side by side with the first and second graspers and moved in a cutting direction along the opening and closing directions to cut the object, and a position setter setting a cutting start position and a cutting end position based on respective positions of the first and second graspers that are grasping the object, respectively.

A torch support and guide apparatus for a plasma cutting torch, for assisting a user in beveling workpiece edges and in sectioning workpieces. The apparatus includes a main support body having a base plate and a pair of support arms extending upwardly from the base plate, the arms configured to support a handle therebetween. The base plate has a cutout notch formed therein to accommodate a clamp subassembly which includes a U-shaped swing member and a clamping bracket. The base plate has a substantially rectangular shape, and has a horizontally extending groove formed in an upper surface thereof. The apparatus also includes a fence with a guide portion and a slide arm integrally attached to the guide portion. The slide arm of the fence fits slidably in the groove of the base plate. A kit for constructing the apparatus and a method of using the apparatus are also disclosed.

The support device comprises: a pivoting arm arranged to be rotatably supported at a first end thereof by a base of the machine for rotation about a first axis of rotation oriented transversely to a longitudinal axis of the tube; a cylindrical roller mounted at a second end of the pivoting arm opposite to the first end with its axis oriented parallel to the first axis of rotation; a variable-profile support member rotatably mounted at the second end of the pivoting arm for rotation about a second axis of rotation parallel to the first axis of rotation; a first driving system arranged to control the angular position of the pivoting arm about the first axis of rotation; and a second driving system arranged to control the angular position of the support member about the second axis of rotation.

A stamping strip manufacturing system comprises a stamping machine forming terminals in a strip by stamping, a supply reel around which the strip to be stamped is wound for supplying the strip to be stamped to the stamping machine, and a recovery reel around which the stamped strip is wound for recovering the stamped strip. The system further includes an autonomous mobile robot on which a cutting tool and a welding tool are mounted. The autonomous mobile robot is adapted to cut off an unqualified strip segment of the stamped strip having an unqualified terminal by operating the cutting tool, and to weld two cut ends of the cut strip to each other by operating the welding tool.

Automated systems and methods for making cuts in large materials, particularly to trim and reduce the sizes of steel plates and slabs and produce therefrom one or more reduced-size pieces, optionally with the ability to reduce or avoid the need to perform a separate deburring operation on the materials after undergoing such cuts. Such a system includes multiple support units aligned in a longitudinal direction of a foundation and longitudinal and cross cutting units translatable in the longitudinal direction for performing, respectively, longitudinal and lateral cuts in a material. The support units are independently translatable in the longitudinal direction and each support unit has a crossmember that extends in the lateral direction, is adapted to at least partially support the material, and is operable to be raised and lowered in the vertical direction while the material is supported by the crossmembers.

A machine for separative machining of a plate-shaped workpiece by a processing beam. The machine has a first movement unit for moving the workpiece in a first direction, a second movement unit for moving a processing head in a second direction, two workpiece bearing supports for bearing the workpiece, and a parts chute. The two workpiece bearing supports are separated from each other by a gap that extends along the second direction. The parts chute is movable between a first chute position and a second chute position so as to move a cut-free workpiece part that has dropped into the gap, laterally away from the gap. The machine includes a receiving unit movable in the second direction, to receive the cut-free workpiece part at a transfer position and transport the workpiece part to one or more discharging positions of the machine along the second direction.

There are provided high power laser and laser mechanical earth removing equipment, and operations using laser cutting tools having stand off distances. These equipment provide high power laser beams, greater than kW to cut and volumetrically remove targeted materials and to remove laser affected material with gravity assistance, mechanical cutters, fluid jets, scrapers and wheels. There is also provided a method of using this equipment in mining, road resurfacing and other earth removing or working activities.

A plasma torch moves to a piercing position. The plasma torch generates a plasma arc and starts a piercing step at the piercing position. Whether the piercing step is completed is determined based on the arc voltage. The plasma torch is held at the piercing position in the horizontal direction from the start of the piercing step until the completion of the piercing step. The plasma torch is moved in a predetermined direction including at least the horizontal direction after the piercing step is completed.

A gantry-type thermal cutting system includes a gantry; a thermal cutting device located on the gantry; a cutting table having a grated steel sheet; and a waste hopper removably connected to the gantry. The gantry is configured to move bi-directionally in a first direction. The thermal cutting device is configured to move bi-directionally in a second direction, the first direction being orthogonal to the second direction. The waste hopper is configured to move synchronously with the gantry in the first direction. The waste hopper is positioned under the gantry to capture waste from a thermal cutting process performed by the thermal cutting device.

A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.
