    Abstract: A device and a method of using the device for construction of baffles that may be used in suppressors or solvent traps for firearms out of metal cups sold as engine block freeze plugs. The device has a bottom die, a top die and an alignment cylinder. The metal cup is transformed into a baffle by placing the metal cup on the bottom die, placing the bottom die inside the alignment cylinder, placing the top die inside the alignment cylinder, and applying compressive forces to the bottom die and top die. A hole may be drilled in the center of the baffle by placing a drill bit into a top die center hole completely penetrating through the top die and coaxial thereto, and drilling through the baffle, the drill bit passing into a bottom die center hole penetrating at least partially into the bottom die and coaxial thereto.

    Abstract: A tool for forming a shaped product has a support body that is fabricated from a first material, such as for instance cast iron. The first material defines a first portion of a forming surface of the tool and has a feature supported thereon. The feature has a layer of a second material that is supported on the first material of the support body, a layer of a third material that is supported on the layer of the second material and a layer of a fourth material that is supported on the layer of the third material. The layer of the fourth material, such as for instance a tool steel alloy, defines a second portion of the forming surface of the tool. During use the first portion of the forming surface and the second portion of the forming surface cooperate to form a desired shape of the shaped product.

    Abstract: The present invention provides a method for manufacturing a steel plate-shaped component which can increase the yield and the working efficiency. When a steel plate-shaped component (1) such as a pole parking is manufactured, a steel disk-shaped initial material (10) is vertically placed in a cavity (41) of a dice (40) of a cold forging die so that the thickness direction of the initial material (10) is perpendicular to a pressing direction. The initial material (10) is pressed through cold forging against the peripheral side portion (11) by a punch (42) while the initial thickness of the initial material (10) is maintained substantially as it is, whereby an approximate component (20) approximating the plate-shaped component (1) is obtained. Subsequently, a margin portion (25) of the approximate component (20) is removed, whereby a half-finished product (30) is obtained.

  • Patent number: 7836740
    Abstract: The axle straightening press has a female jaw and a male jaw each with a rectangular shape, a mating surface, and a transverse half channel. The dowels of the male jaw fit into holes in the female jaw upon a diagonal line on the mating surface. Preferably, the press has two identical jaws, inverted, and closed upon each other. Each jaw has a generally rectangular shape with a mating surface, a dowel, a transverse half channel, and a hole. The half channel is less than one tenth the thickness of said jaw and has flared ends for shaping the head of an axle into a cone. A Cub Scout places an axle in the channel between the jaws and strikes the press with a hammer. Removing the axle from the press, the Cub Scout places a wheel on the axle, and installs the axle upon a model car.

  • Publication number: 20100107718
    Abstract: The invention provides a die set comprising an annular necking die and a knockout punch for necking-in a metal container, and a method of necking. In the method, in at least one necking-in step, the metal container is both reduced in diameter and the container wall is redrawn to minimize circumferential irregularities of wall thickness and/or circumferential rippling of the container wall caused by the reduction of diameter. The die of the die set is provided with a redraw surface to achieve this redrawing effect.

  • Publication number: 20100107719
    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.

  • Publication number: 20100000287
    Abstract: The invention is a multi-mode hammering machine that operates in a rigid mode, a flexible power hammer mode and a machine press mode to contour, shape and form sheet metal products. In all three modes, a ram is linearly stroked toward and away from a fixed die by a common ram drive assembly that includes a lever drive assembly and a reciprocating lever. The lever drive assembly moves in a rigid non-flexing manner. The reciprocating lever includes a rigid mode and a flexible mode. A conversion pin is used to engage one and simultaneously disengage the other. The lever drive assembly includes a control link that interfaces with a stroke adjustment mechanism. The gap adjustment mechanism is located at the fulcrum of the reciprocating lever. Both stroke length and gap are adjusted independently during the operation while the ram is cycling.

    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.
