Abstract:
A diamond wire cutter (100), using an adjustable length pulley system, a diamond wire saw (1), and a movable pulley cart (10), can perform a through-cut of complete sections of a structure such as a tubular (200) subsea by fitting a chain about an outer surface of the structure, securing the chain to the movable pulley cart and using the chain to move or otherwise guide the movable pulley cart about the outer circumference of the structure to cut while using a diamond wire (50) to effect a cut between the movable pulley cart and the diamond wire saw (1).
Abstract:
A winder unit (1) for winding cutting line (41), for vehicle glazing panel removal, has a rotatable spindle shaft (61) for winding the cutting line (41) and a ratchet device (90) mounted to the spindle shaft (61) by means of a one-way rotational bearing or clutch (75). Typically the ratchet device (90) has a component mounted to rotate in unison with the one-way rotational bearing or clutch. The improvement provides a rotational directional control providing 2 one-way rotational control devices in concert.
Abstract:
Extrudate 10 materials that are in a formable and/or collapsible state present multiple challenges for cutting into lengths, particularly when the extrusion profile Includes one or more openings 12 (e.g., running the length of the extrudate 10). The invention is directed at apparatus, devices, systems and methods for cutting the extrudate 10. A cut 64 (e.g., and initial cut) into the extrudate 10 is performed using an ultrasonic knife 27 that vibrates at one or more frequencies. Preferably the cut using the ultrasonic knife 27 is a partial cut 64. A further cut through the extrudate 10 may be made using a secondary cutting tool such as a wire cutter 68, The secondary cutting tool preferably creates a final cut 66 through the extrudate profile, for cutting a part to a length. The ultrasonic knife 27 preferably travels In the horizontal direction at a rate faster than the extrudate 10 while cutting.
Abstract:
The invention relates to a method for monitoring for wire breaks while hard solids are cut by means of a span of wire, wherein the solid is guided through the span of wire, and a direct current is conducted by the span of wire. The direct current produces a voltage across the span of wire. The voltage is monitored by a sensor, which interrupts the cutting process when a voltage-deviation signal caused by a wire break is received. The invention further relates to a wire saw for carrying out said method and to the use of the method and/or of the wire saw to cut hard, preferably brittle solids, preferably metals and semimetals, preferably mono- and polycrystalline silicon crystals, ceramics, sapphire, and germanium.
Abstract:
A dispensing system for dispensing cutting wire to be used in a glazing panel cut out procedure has a mounting device with a docking station for docking a wire store device. The wire store device mounts on the docking station in order to dispense the wire. The mounting device can have a rotary means operable to pay out cutting wire from the system. The rotary means is controllable to adjust the applied torque required to operate the rotary means.
Abstract:
A device for cutting a length of pipe includes a clamp portion for clamping around a length of pipe and a bow moveable with respect to the clamp portion that retains a loop of diamond embedded wire. The device further includes a feed for driving the bow with respect to the clamp portion and a detector for detecting bending of the wire and a control responsive to the detector for controlling feed rates. The device is made of modular parts and has synchronizing arms for clamping around a length of pipe. In one embodiment, the wheels are retained in enclosures with slots through which the cutting wire passes.
