Tool Comprising Closed Periphery Deforming Passageway Patents (Class 72/467)
  • Patent number: 10131021
    Abstract: In a method for manufacturing a forging die with improved wear resistance, hot-work tool steel is obtained in which Al is added as a de-oxidizing agent during manufacture of the hot-work tool steel in a sufficient quantity such that it is only partially consumed during the de-oxidizing process, leaving Al in a range of greater than 0.015 weight percent after the de-oxidizing process. The forging die is shaped from the hot-work tool steel. By a subsequent nitriding process, a hardened surface is created on the forging die by heating in a nitriding atmosphere by interaction with the Al to improve a hardened surface on the hot-work forging die resulting in an improvement in wear resistance.

    Abstract: Modular extrusion die tools for extruding an extrudable material into an extruded article. In at least some embodiments, an extrusion die tool comprises a base, a sizing plate, a mandrel, and a die holder. When the sizing plate and mandrel are removably inserted into the base, and the base is removably inserted into the die holder, a billet of extrudable material may be injected under high pressure into the die tool. As it exits the die tool, the material is extruded into a desired shape. Because of the extreme forces to which the extrusion die tools are repeatedly subjected, some portions of the die tools can wear out relatively rapidly. Other portions, however, wear at a much slower pace. Consequently, certain portions of the die tool may need to be replaced more frequently than other portions. Because the extrusion die tools of the present invention are modular, the highly-worn portions of a die tool may be replaced without replacing the entire tool.

    Abstract: The exemplary embodiments provide a die set comprising a knockout punch and a necking die for necking-in a metal container preform. In an axial direction from front to back of the die, the die has an inwardly tapering in-feed surface, a forming radius, a generally cylindrical land having a die bore diameter, a discharge surface and a relief surface having a diameter larger than the die bore diameter. The land has an axial length of less than 0.1 inch. It is believed that such a length limits the number of metal contacts with the land (rebounds between the knockout punch and the land) to one or two as a metal container preform is necked in the die in conjunction with a knockout punch having a punch diameter that provides a gap between the knockout punch and the land. While the gap may be larger than the topwall thickness of the metal of the preform within the gap, it may alternatively be the same as, or smaller than, the thickness (by up to 10%), to effect re-resizing of the container wall.

    Abstract: A method to manufacture a steel die having a Physical Vapor Deposition wear resistant coating on a profile surface and a steel die formed thereby is disclosed. The steel die is subjected to quenching and tempering to achieve a Rockwell hardness in the range of about 40-45 Rc and then subjected to machining to form a profile surface. The surface is then subjected to Physical Vapor Deposition of a wear resistant coating that may be multiple layers of CrN, AlCrN, TiCrN, TiN, TiCN or TiAlN, and preferably is alternating layers of TiN—TiCN—TiN. The coating is applied at a sufficient thickness to impart wear resistance to the steel die. The steel dies are useful in sheet metal stamping operations.

    Abstract: Various embodiments of the present invention are directed to wire-drawing die assemblies. In one embodiment, a wire-drawing die assembly includes an assembly of at least three die segments. Each of the die segments includes an inner die surface comprising a superhard material. The inner die surfaces of the die segments form a die cavity. In another embodiment, a wire-drawing die assembly includes an assembly of die segments, each of which includes an inner die surface. The inner die surfaces of the die segments form a die cavity. Each of the die segments further includes two sidewalls, with the inner die surface extending between the two sidewalls. At least a portion of each of the two sidewalls may be oriented nonparallel relative to a wire-drawing axis of the die cavity.

  • Patent number: 7401486
    Abstract: A die through hole has an inside surface including a bell portion, an approach portion, and a bearing portion from the entrance side. The diameter of the approach portion is D1 on its entrance side and D2 on its exit side and gradually decreases from the entrance side to the exit side. The diameter satisfies Equation (1): 0.7?D2/D1<0.97. The die half angle of an inside surface where the diameter D3 is D2/0.97 is not less than the die half angle R2 of an inside surface nearer to the approach portion exit side than the inside surface where the diameter is D3. The axial distance LR from the inside surface where the diameter is D3 to the inside surface where the diameter is D2 satisfies Equation (2): 20?LR/((D3?D2)/2)?115. The through hole diameter at the bearing portion is fixed at D2, and the length is LB and satisfies Equation (3): 0.3?LB/D2?10.
