摘要： The invention relates inter alia to a method for cutting a workpiece, in particular a blank or a component, comprising the following steps: inserting the workpiece into a cutting device, wherein the cutting device comprises a first tool half having at least one workpiece holder and at least one first cutting means, which comprises a first cutting edge and a contact surface, and a second tool half having at least one second cutting means having a second cutting edge and a contact surface, clamping the workpiece by means of the workpiece holder and the contact surface of the second cutting means, cutting the workpiece by means of the cutting means, the workpiece undergoes, prior to cutting, both a first prebending, which is produced substantially in the opposite direction counter to the cutting direction, and thereafter a second prebending in the cutting direction.

摘要： A coil slitting tool in the form of a rotary serrator knife for use on coil slitting machines comprises a plurality of serration undulations disposed on one or more faces about the outer periphery. The rotary serrator knife tool may comprise a concentrically located bore about an inner diameter for mounting on an arbor and may further incorporate a keyway. The rotary serrator knife may be formed from an assembly comprising, a central rotary disk about which mount one or more removable inserts comprising the serration undulation portion. The one or more removable inserts may comprise serration undulations on one side or two sides and mount substantially to the perimeter of a mounting disk by use of fasteners.

摘要： A cutting method using a stamping press according to the present disclosure is a method to cut a workpiece that is configured from a first metal sheet and a second metal sheet joined at a weld portion and that has a heat-affected zone around the weld portion, in which the workpiece is cut using a punch. The punch includes a flat portion and a projecting portion projected more toward the workpiece than a flat portion of the punch. The workpiece is positioned with respect to the punch at a position such that the projecting portion starts cutting at least at one out of the heat-affected zone or the weld portion before the flat portion cuts the workpiece. The workpiece is then cut by moving the punch and a die relative to each other in this state of positioning so as to shear across the weld portion on the workpiece.

摘要： The present disclosure proposes a tool for shear cutting, wherein the tool has a lower blade, a hold-down device and an upper blade, wherein the lower blade has a pressure-loaded surface and a cutting surface, wherein it is possible for a workpiece to be arranged between the hold-down device and the contact surface, wherein the upper blade is movable in relation to the lower blade along a cutting direction predetermined by the cutting surface, wherein a contour profile of the lower blade has a jagged elevation at the transition from the cutting surface to the pressure-loaded surface.

摘要： An apparatus for cutting off concrete, wooden, and/or metal piles, casing, conductor pipe and other metal tubulars, uses a metal frame and a metal blade linearly moveable within the frame, the blade being hydraulically and/or pneumatically driven to puncture and then slice and split through the metal being cut off, the cutting surface of the blade having a removable, centralized puncture point located essentially at the projected intersection between two concave cutting surfaces.

摘要： A rotary cutting apparatus includes a pair of cutting tools each having a cutting blade along a tip end of its outer peripheral portion having a mountain-shaped cross section, and cuts a cylindrical material into pieces with a predetermined width by sandwiching the cylindrical material between the cutting blades so the cutting blades are respectively placed on inner and outer peripheries of the cylindrical material, and relatively rotating and moving the pair of cutting tools along an entire circumference of the cylindrical material. A second imaginary line connecting an axial center of the cylindrical material and an axial center of the inner peripheral-side cutting tool is shifted in a circumferential direction of the cylindrical material about the axial center of the cylindrical material with respect to a first imaginary line connecting the axial center of the cylindrical material and an axial center of the outer peripheral-side cutting tool.

摘要： First and second dies can be coupled to a pair of arms on a threaded rod cutting machine. The first die has a body with a front face, a rear face, a side face extending between the front face and the rear face, and a first threaded recess in the first side face and configured to receive a threaded rod to be cut. Crests and troughs of the first thread are aligned with troughs and crests of the threaded rod when the first die engages the rod. The second die has a body with a front face, a side face extending between the front face and the rear face, and a second threaded recess in the side face and configured to receive the threaded rod. Crests and troughs of the second thread are axially offset from troughs and crests of the threaded rod when the second die engages the rod.
