  • Publication number: 20130298628
    Abstract: An apparatus and method for manufacturing using a hydroforming process. The apparatus includes: upper and lower molds; first and second axial punches which are disposed on opposite sides of the steel substance so as to be movable towards each other and which have front surfaces configured so as to be insertable into each other; first and second pressurization cylinders which move the first and second axial punches towards each other and insert them into each other, thus forming a sealing space defined by the first and second axial punches and a pressurization space defined by the steel substance and the first and second axial punches; and a control unit which, through an oil-pressure passage formed in at least one of the first and second axial punches, supplies fluid into the pressurization space to pressurize the steel substance, thus forming the large caliber product.

  • Patent number: 8308175
    Abstract: Provided is a tubular torsion beam for rear suspensions of vehicles, which is produced according to a more durable design capable of improving roll stiffness and roll strength of the tubular torsion beam. The tubular torsion beam is produced by pressure-forming a tubular steel member through hydroforming such that the tubular torsion beam has a cross-section varying along an entire length thereof, with opposite ends having a closed cross-section and mounted to respective trailing arms, a middle portion having a V-shaped open cross-section, and a transitional portion having a varying cross-section and connecting the middle portion to each of the opposite ends. During the process of manufacturing the tubular torsion beam, the opposite ends of the tubular steel member are fed using respective axial punches of a hydroforming machine, so that the opposite ends are thicker than the middle portion.
