Abstract:
A method of operating a progressive die wherein the progressive die acts on a work piece having an elongated body with a blank at one end. The work piece is supported by a bandolier which is also formed in the progressive die. The progressive die acts on each blank.
Abstract:
A method of making bullets on a progressive die wherein the progressive dies acts on a work piece having an elongated body with blanks at each end. The work piece is supported by a bandolier which is also formed in the progressive die. The progressive die forms each blank into a bullet, effectively doubling the output of the progressive die relative to a progressive die that acts upon a work piece that supports, or is, a single blank.
Abstract:
A method of making flechettes employing the use of a progressive die which forms (a) wire that results in the flechette, and (b) strip material that results in a carrier for the finished flechettes. The carrier, which is a bandolier apparatus, is used for progressing the flechette through the progressive die at various forming stations. After forming of the flechette in the die is complete, the final flechette can be severed from the bandolier, or the flechette can remain intact with the bandolier for post-forming operations, such as coating/finishing. The bandolier is thus a novel approach to transporting the flechettes in both forming and post-forming processing.
Abstract:
A clamping jaw for gripping wire stock used in nail production machines includes a quick change system that allows efficient replacement of a removable tool insert. The clamping jaw includes a main body that is partially split so as to define a gap between first and second opposing clamping fingers having a recess portion there between for receiving and retaining the insert. The main body includes a top surface, a bottom surface, a central bore that extends between the first and second surfaces, and a countersunk cavity formed in the bottom surface. A tapered projection formed from the first and second clamping fingers extends into the countersunk cavity. A clamping member, having a tapered recess for receiving the projection, is positioned in the countersunk cavity. A fastener is tightened to draw the clamping member onto the projection to close the clamping fingers in order to grip the insert.
Abstract:
An apparatus and a process for continuously producing an assembly of headed fasteners of uniform length. The fasteners, fixed in either an equally spaced apart parallel relationship or in a contiguous parallel relationship, are produced by providing at least one strand of wire in straight and untwisted form, cutting the wire into headless fasteners of uniform length, transferring the headless fasteners onto a guide track in parallel, adjacent alignment, collating the headless fasteners to form a continuous web thereof, conveying the continuous web of headless fasteners into a clamping block and then forming a head from one end of the fasteners to form the headed fastener. The apparatus for producing the headed fastener assembly includes means for providing the wire in straight untwisted form, means for cutting the wire into headless fasteners, means for transferring the headless fasteners onto a guide track in parallel adjacent alignment, means for collating the fasteners a conveyor to convey the continuous web of headless fasteners to a head-forming means, and severing means for selectively cutting the continuous web to produce the assemblies or clips of headed fasteners.
Abstract:
An upsetting device for upsetting the ends of elongated workpieces such as wire pieces and the use of such a device in a wire-working nail press. The device includes an upsetting tool moveable forwards and backwards by means of an upsetting carriage. The upsetting tool is separate from the upsetting carriage and mounted to be displaceable in its direction of movement in its own longitudinal guide separately from the carriage guide. The upsetting tool also positively bears against the part of the upsetting carriage which acts on it.
