  • Patent number: 5794483
    Abstract: A fin forming device folds fin material into a plurality of corrugations by creating a fold radius at each fold. The device comprises a substantially rectangular plane of metal having a front side, and an opposing back side. The perimeter of the plane is defined by a top edge which is applied to the fin material to form the fold radius, a bottom edge, and a pair of opposing side edges. Initially, each of the edges has a substantially similar thickness. An angled surface is created on at least one side of the plane, commencing in an interior area of the plane below the top edge of the plane and terminating at the top edge of the plane. This creates an angled blade surface along at least a portion of the top edge of the plane. The angled blade surface has a narrower thickness than the initial edge thickness.

  • Patent number: 5557835
    Abstract: The invention concerns a method for riveting a packet (50) of sheets (51,52) by means of unannealed aluminum rivets made from an alloy harder than that of the relatively soft AD rivets in common use; this method is characterized by the fact that the expansion of the head to be formed at the shank end (58,59) of the rivet during the riveting process is controlled by a snap-tool (62) which encloses the shank end (58,59) at first loosely. When the expansion of the head diameter approaches D=1,5 d (with d the rivet diameter), i.e., the limit above which cracks form in the head, the tool (62) prevents further deformation and forces the material of the head to deflect towards the central portion of the rivet shank (57) which subsequently expands and widens the hole (53) sufficiently to make the riveted joint last considerably longer. The good loosely and, later in the process, tightly fitted enclosing of the shank end (58,59) by the snap-tool (62) allows the riveting to be done manually.

  • Patent number: 5291772
    Abstract: An electrical connector crimping tool has a head with a stationary anvil and a movable ram. The anvil has two angled contact surfaces for contacting a connector. The ram has a front with a pyramid and angled side portions. The pyramid is suitably sized and shaped such that the angled side portions of the ram can contact the anvil angled contact surfaces to stop forward advancement of the ram without the pyramid contacting the anvil.

  • Patent number: 5007268
    Abstract: An edge-finishing device comprises a drive unit (L), a holder (M) and a notched tip (N). The tip combines a number of geometric features known as land radius (Y), flank faces (K), flank radii (I) and root radius (J). Typical useage of the device requires a tip to be fitted into the holder, the tip being then offered against the workpiece using the flank faces for guidance. The land radius determines the contact area. The tip impacts against the workpiece and bends the protrusions over. The flank radii then beat the protrusions thin enough for them to break off or be driven off. The tip continues to impact until the finished edge conforms to the root radius.

  • Patent number: 4805495
    Abstract: A bolt head reforming tool for extracting bolts that have had their head stripped such that they cannot be removed with a wrench. A hollow tool has a central opening which has a lower portion large enough to pass over the head of the bolt and an inner portion which is smaller than the head of the bolt such that the tool can be driven onto the head of the bolt with a hammer such that the smaller portion cuts the head of the bolt to reform it to its original position. The tool may have a staggered inside cutting edge so that as the tool is driven further onto the head of the bolt, a third inner surface also cuts the head of the bolt. The outer surface of the tool is formed such that a wrench can be connected thereto so as to turn the tool and the bolt to thus remove the head.

  • Patent number: 4630463
    Abstract: A die particularly adapted to drive a rivet, where the head of the rivet has a relatively steep circumferential side surface. The die engages the rivet head in a manner that initially the middle portion of the die driving surface exerts substantial force into the shank portion of the rivet, after which the die driving surface comes in greater overall driving engagement with the entire rivet head. Further, the die has a circumferential lip which limits lateral movement of the die relative to the rivet head.

  • Patent number: 4249408
    Abstract: This invention provides a method for cold extruding 18% nickel maraging steel to form an article of manufacture, such as a sub projectile blank for the manufacture of cannon rounds which includes performing a series of cold extrusion operations on an extrusion blank with a tapered punch to produce a combination forward extrusion and backward extrusion. On the first cold extrusion operation a tapered hole is formed in the extrusion blank and the extrusion blank is elongated. Subsequent cold extrusion operations progressively elongate both the extrusion blank and the tapered hole. The punch and die geometry are such that the tapered hole is elongated by penetration of the punch into the blank and additionally backward extrusion of the material around the punch. Additionally, as the tapered hole becomes increasingly longer, a floating punch is employed wherein at least a portion of the punch is supported by the walls of the tapered hole.
