  • Patent number: 9630235
    Abstract: A roller hemming processing apparatus adapted to perform a hemming processing has a hemming die, on which a panel-like workpiece having a hemming flange portion on a periphery portion thereof, is positioned and supported, a roller hemming processing tool that is moved along a longitudinal direction of the hemming flange portion to bend the hemming flange portion at a root portion thereof while pressing the hemming flange portion toward the hemming die, and a nesting block disposed at a part of the periphery of the hemming die. The nesting block performs positioning of the workpiece by being brought into contact with the root portion of the hemming flange portion with which the workpiece is formed. The nesting block is elastically supported to be retractable in the pressing direction and to be swingably displaceable in the longitudinal direction of the hemming flange portion.

    Abstract: A method for producing an ultrathin-wall seamless metal tube, which employs a cold pilger mill of mechatronics drive type including a mechanism to give a feed and a turn angle to a tube material, utilizes a roll having a tapered groove whose diameter gradually increases or gradually decreases from an engaging entry side to a finishing exit side of a pair of rolls, and a tapered mandrel whose diameter similarly gradually increases from the engaging entry side to the finishing exit side to elongate the tube material by reducing a wall thickness while expanding a mid-wall diameter of the tube material. By giving amounts of a turn angle and/or a feed equivalent or nearly equivalent to the forward stroke to the tube material immediately before the start of a backward stroke, it is possible to achieve a further increase in the reduction-rate of rolling, a further reduction of wall thickness, and improvement of dimensional accuracy of the product.

    Abstract: In a roller hemming method for folding a flange erected from a workpiece by pressing a working roller against the flange and moving the working roller relative to the flange, the flange is folded by: a first temporary bending step of bending a tip-side portion of the flange into a state that the tip-side portion is inclined; a second temporary bending step of bending a remaining, base-side portion of the flange into a state that the base-side portion is inclined; and a full bending step of bending the thus-bent flange into a final shape so that the flange is into contact with a flange-proximate portion.

  • Patent number: 7895870
    Abstract: An exemplary embodiment of the invention provides a method for producing an ultra thin wall metallic tube by cold working method with significant wall thickness reduction. In a method for producing the metallic tube with a cold pilger mill according to the invention, cold rolling is performed while tube diameters are being expanded using rolls having tapered groove dies whose calibers increase from an engaging entry side toward a finishing exit side. In a method for producing the metallic tube with a drawing machine according to the invention, cold drawing is performed while the tube diameters are being expanded using a solid die whose calibers increase from an engaging entry side toward a finishing exit side and a plug of a tapered mandrel bar whose diameters increase from an entry side of the die toward an exit side. In the metallic tube producing method, a maximum diameter of the plug or tapered mandrel bar may be larger than an outside diameter of the mother tube.

  • Publication number: 20090288465
    Abstract: A method urges a blank along an axial direction between a movable bending tool and a stationary counter-tool and, while the blank is being moved forwards, of moving the bending tool from a neutral position, in which the blank is not bent, to a working position, in which the blank is bent to the desired bending centerline radius, the working position being rotated with respect to the neutral position by a given angle of rotation depending on the desired bending centerline radius. The method further includes urging the blank between a pair of shoes upstream of the bending tool so as to make the deformation of the blank easier, and the step of moving the bending tool from the neutral position to the working position is carried out by controlling at least two degrees of freedom of the movement of the bending tool in the plane defined by the axial direction and by a transverse direction perpendicular to the axial direction.

  • Publication number: 20090255312
    Abstract: Incoming tubes are turned and fed into a pilger mill by use of a single gearbox using a rotating dual track drive system. The dual track system holds the incoming tube while tube reducing (metal tube forming) occurs by the pilger tooling. When the pilger tooling is free of the incoming tube product, the dual track drive moves the tube into the pilger tooling by feeding an incremental amount of tube product. The dual track drive also indexes the incoming tube at the correct time and at a pre-determined amount. Additionally, the gearbox sub-assembly bumps the tube at a pre-determined time while the tube is free from the tooling.

  • Publication number: 20090217726
    Abstract: A hemming apparatus is provided for use with a robot in performing a hemming operation. The hemming apparatus comprises a support housing which mounts to a machine and has a pressurizable interior chamber having forward and rearward portions. A slide member includes a piston which is disposed in the chamber, and a plunger extends outwardly from the piston. Means are provided for attaching the housing to a nose having a central passageway. A bearing shaft is disposed within the central passageway, and means are provided for connecting the bearing shaft to the plunger. A hem roller is attached at the end of the bearing shaft. The rearward and forward portions of the chamber are connectible to a source of fluid pressure such that adjusting the chamber pressures moves the piston, thereby causing the bearing shaft to drive the hem roller into engagement with a work piece.

  • Patent number: 7516638
    Abstract: A portable hand tool includes a frame for guiding a sheet of material, e.g., sheet metal. A pair of shafts are spaced from each other and are selectively slideable relative to the frame to define a plurality of adjustment positions. A pair of rollers are respectively mounted to the shafts for deforming the sheet of material between the rollers. An adjustment rod is mounted to and extends outwardly from the frame. A support interconnects the shafts and an adjustment device is rotatably engaged with the support. A coupling device is disposed about the adjustment rod and is moveable between an engaged position and a disengaged position. In the engaged position, the coupling device couples the adjustment rod and the adjustment device to lock the shafts and rollers laterally relative to the frame. In the disengaged position, the shafts and rollers are slideable relative to the frame between the adjustment positions.
