In a first stage or operation, at least one shear initiation breakthrough opening is formed through the ultra-high strength material sheet at an interior location. A leading terminal end of each of at least two inclined shearing edges of an interior opening shearing tool is positioned in the at least one shear initiation breakthrough opening. The interior opening shearing tool is different from the breakthrough opening forming tool. In a second stage or operation, shearing of the material is initiated from the at least one shear initiation breakthrough opening by advancing the at least two inclined shearing edges of the interior opening shearing tool against the ultra-high strength material sheet and relative to a corresponding shearing tool.

The invention is to a device and method, for cutting a can blank in which case an end section of the can blank is severed. The can blank is moved by means of a conveyor arrangement at a constant speed about a first axis of rotation. Preferably, a laser beam is used as the cutting means. A deflecting arrangement deflects the laser beam to a focal point where the side surface of the can blank is located. Due the rotation of the can blank about its longitudinal axis, the axial end section of said can blank is severed. The focal point of the laser beam does not change relative to the longitudinal axis of the can blank during the laser cutting operation.

A hard disk drive desledder comprises a support and a cutting member. The support is configured to receive and to support a hard disk drive assembly that includes a hard disk drive and a sled. The cutting member has at least two cutting edges corresponding to respective portions of the sled. The cutting member is movable from a first position spaced apart from the support and a second position adjacent the support to cause the at least two cutting edges to cut portions of the sled to allow the hard disk drive to be removed from the hard disk drive assembly. Related desledding methods are also described.

A shearing implement for use with an excavator has a thumb having a grasping side and a cutting side and being pivotably attachable to the boom. A shearing blade member is pivotably attached to the cutting side of the thumb. A linear actuator has a first end attached to the shearing blade member and a second end attachable to the boom or the thumb so that extension and retraction of the linear actuator causes the shearing blade member to rotate relative to the thumb.

Provided are a method for splitting longitudinally an end part of a metal plate or a metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed; a metal part manufactured by such method; and a method for bonding such metal part. The present invention is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

A machine that applies both cutting and shearing action to casting-type metal debris and scrap (hereafter debris), and thus efficiently reduces both brittle and ductile metals to a useful size. The machine comprises a fixed anvil and a reciprocating jaw, the anvil defining an array of spaced anvil plates and the jaw defining a complementary array of spaced jaw V-shaped jaw bars whose upper and lower legs or lobes are alternately reciprocated in an arc into and out the anvil plate array.

An apparatus for manufacturing magnet segments constituting a field pole magnetic body formed by cleaving a magnetic body at a plurality of scheduled cleaving parts is provided. The apparatus includes placing tables on which a magnetic body having a coating applied to an outer surface thereof is placed, a pressing unit that cleaves the magnetic body by pressing the magnetic body from an opposite side of an incision at a scheduled cleaving part arranged between two of the placing tables, and a cutting unit that cuts the coaling of the magnetic body present at the scheduled cleaving part after the magnetic body is cleaved, by applying a moment in a direction opposite to a moment generated in the magnetic body between the two placing tables at the time of cleaving. Cleaving divides the magnetic body into a magnet segment and an uncleaved magnetic body.

A surgical rod scorer is provided. The surgical rod scorer includes a pair of elongated shaft members that are pivotably coupled to one another and movable from a spaced-apart configuration to an approximated configuration. Each of the shaft members includes a handle member that is configured for gripping by a user and jaw member that is configured to support respective first and second cutting assemblies thereon. The first and second cutting assemblies each include one or more cutting elements thereon configured and dimensioned to score surgical rod when the jaw members are in the approximated configuration and rotated about the surgical rod.

A sheet metal part (20) is produced from a starting sheet metal (27) and has at least one side edge (32) extending along the grain boundaries of the sheet metal material. Separating or breaking the starting sheet metal (27) at a separation location (28) is induced by forming a notch in the starting sheet metal or by cutting or scratching into the starting sheet metal. The starting sheet metal is clamped via a first portion (30) adjacently to the separation location (28). A second portion (31) disposed on the side of the separation location (28) opposite the first portion (30) is acted on to produce a bending moment M about a bending axis B at the separation location (28) and/or to produce a tensile force Z directed away from the separation location (28).
