A method of making steel fibers, preferably for use as a concrete additive, and for the supply thereof in making steel fiber concrete, characterized in that to form the steel fibers (2) first a sheet-metal strip (1) is notched either on one face or both faces so as to form steel-fiber wires (4) that are initially connected together by webs (5), and that further, for subsequently converting the webs (5) into thin easily mutually separable separation webs forming separation surfaces that are fracture-rough and low in burring upon separation, the steel-fiber strip is subjected to a flexing process in which each web (5) is subjected to multiple bending deformations about its longitudinal axis in such a way that incipient cracks are produced at the webs (5) due to fatigue fracture and thus the separation webs are produced.

A tool for removing a fastener head from a fastener includes a body that includes an alignment surface configured to couple substantially flush against a structural surface proximate the fastener head. A blade coupled to the body includes a tip configured to sever the fastener head from the fastener as the blade is moved in a first direction generally parallel to the alignment surface from a first blade position to a second blade position. The tool also includes a force transfer member coupled to the body for movement parallel to a longitudinal axis of the force transfer member. The longitudinal axis is oriented at an acute angle with respect to the first direction. The force transfer member is configured to move the blade from the first blade position to the second blade position in response to an impulse received by the force transfer member.

After a connecting rod for an engine is formed, it is broken or fractured at a fracture point to allow the connecting rod to assemble around a portion of a crankshaft. However, before fracturing the connecting rod, the connecting rod is provided with a layer of paint across the eventual fracture point such that when the connecting rod is fractured the paint extends across both sides of the fracture point. Also before fracturing the connecting rod, serial numbers or symbols are etched into the paint on either side of the eventual fracture point. These serial numbers are unique to that connecting rod, and have similar indicia on either side of the connecting rod. The combination of the paint and serial numbers increase the ability of an assembly worker to assure matching parts of an original connecting rod are re-attached during assembly about the crankshaft.

A shearing blade for a cutting device includes a main body that has a seat and a blade insert that is arranged on the seat and forms a cutting wedge, wherein the cutting wedge forms a cutting edge via a flank face and a pressure face at an angle to the flank face. The seat has at least one undercut face that acts in a direction transverse to the flank face. When the blade insert is inserted, the undercut face interacts with at least one form-closure face formed on the blade insert, whereby a form closure taking effect transversely to the flank face is established. The blade insert is fastened to the main body by at least one pin-shaped plug-in connection element, which is oriented perpendicular to the flank face and which is arranged in aligned holes in the main body and in the blade insert.

A shear bonding device and a shear bonding method of metal plates are disclosed. The shear bonding device may include: an upper shear bonding mold having more than one upper perpendicular tooth and more than one upper slanted tooth formed alternately on a front end surface thereof; a lower shear bonding mold overlapped with the upper shear bonding mold in a vertical direction by a predetermined width below the upper shear bonding mold, and having more than one lower perpendicular tooth corresponding to the more than one upper slanted tooth and the more than one upper perpendicular tooth corresponding to the more than one lower slanted tooth formed alternately on a front end surface confronting the upper shear bonding mold; an upper heating clamper including a front end surface contacting with the upper perpendicular tooth of the upper shear bonding mold and adapted to generate heat by receiving power from a power supply; a lower heating clamper including a front end surface contacting with the lower perpendicular tooth of the lower shear bonding mold and adapted to generate heat by receiving power from the power supply; upper and lower pressing cylinders moving the upper and lower shear bonding molds upwardly or downwardly so as to apply load; and upper and lower clamping cylinders moving the upper and lower heating clampers upwardly or downwardly so as to apply clamping force and load, wherein the metal plates are disposed between the upper shear bonding mold and heating clamper, and the lower shear bonding mold and heating clamper.

The various embodiments disclosed and pictured illustrate a hammer for comminuting various materials. The embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The hammer includes a connector end having a rod hole therein, a contact end for delivery of energy to the material to be comminuted, and a neck affixing the connector end to the contact end. The neck is formed with at least one neck recess therein. In other embodiments, one or more shoulders are positioned around the periphery of the rod hole for added strength. In still other embodiments, the contact end is configured with more than one contact surface.

A shearing implement for use with an excavator is disclosed. The shearing implement comprises 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.

A tool attachment system for demolition, recycling, and/or material processing applications wherein a platform is part of a jaw of a jaw set. A segment with working surfaces is attached to the platform such that the segment shields the platform from a workpiece. Additionally, the segment may be customized for a particular task thereby providing optimum performance.

An indexable piercing tip mounts to a nose portion of one of the jaws of a heavy-duty demolition shears so as to enclose and protect top, bottom, front, and two opposing side surfaces of the nose portion during use of the shears. The piercing tip has a first operative position in which a first set of piercing and shearing edges of the piercing tip are presented for use. When the first set gets dull or worn, the piercing tip can be rotated/indexed 180 degrees so as to present a second set of piercing and shearing edges of the piercing tip for use.
