  • Patent number: 10737308
    Abstract: A method of, and arrangement for, producing shaped hollow metal objects by a hot process. A metal hollow semi-finished-product with at least one opening is heated to a forming temperature and placed into a cavity, whose shape corresponds to the desired final external shape of the hollow object. Then the cavity is sealed and water and/or steam is introduced therein. After the final shape of the semi-finished-product is achieved, the semi-finished-product is removed. The cavity is formed by a split mould, whose opening's entry edge has an expanded portion, against which a sealing feature is oriented. The outer surface of the sealing feature is arranged to close against this expanded portion. The sealing feature is also provided with a means of supply of water and/or steam, and a tube through which the water and/or steam is supplied. This tube extends into the interior space of the semi-finished-product, and can be provided with nozzles.

  • Patent number: 9630230
    Abstract: A device and a method for forming by stamping a curved metal sheet. The device includes a punch made of deformable and substantially non-compressible material, a hammer configured to strike the punch along the longitudinal axis Z. A generator to generate a magnetic field configured to impart on the hammer a speed greater than a predetermined speed in the Z direction. The device further includes a matrix of predetermined shape, approximately rotationally symmetrical about the longitudinal axis Z. The punch is rotationally symmetrical about the longitudinal axis and configured to be disposed in front of the matrix. The punch has a longitudinal dimension in the same order of magnitude as its dimension perpendicular to the longitudinal axis Z.

  • Patent number: 9545657
    Abstract: A method of hydroforming a vehicle rail from an extruded aluminum tube includes the steps of positioning the extruded aluminum tube into a hydroforming die and partially closing the hydroforming die. Next is the step of applying a liquid under a first level of pressure to the extruded aluminum tube in the hydroforming die. This is followed by engaging an inner radius of a bend in the extruded aluminum tube with the hydroforming die before completely closing the hydroforming die and increasing the level of liquid pressure in the workpiece to a second level to form and hydro-pierce a part from the extruded aluminum tube.

  • Patent number: 9127444
    Abstract: An apparatus and method are shown for installing a metal transition end on an open end of a length of plastic pipe having an outer diameter and an inner diameter by placing a stiffener sleeve within the inner diameter of the plastic pipe at a point which is circumscribed by the metal transition end. An actuating sleeve, carried on the draw rod, allows the stiffener sleeve to be installed in a desired location within the open plastic pipe end by using the draw rod to first position the stiffener sleeve in the desired location. The metal transition end is provided with an internal relief groove which accepts any excess plastic material forced past the stiffener sleeve during the installation process.
