  • Patent number: 11898628
    Abstract: A device for cold working pipe elements has two or more cams, each having a gear which meshes with a pinion to turn all of the cams. Each cam has a cam surface with a region of increasing radius and may have a region of constant radius extending around a cam body. Each cam also has a traction surface extending around a cam body. A region of reduced radius in each cam surface is aligned with a gap in the traction surface of each cam. The regions of reduced radius and gaps provide clearance for insertion and removal of the pipe element between the cams to form a circumferential groove when the cams are rotated.

  • Patent number: 11897017
    Abstract: A hybrid method for forming a material blank includes placing a material blank to be deformed between a die and a blank-holder. The material blank is deformed by stamping using at least one punch in order to obtain a pre-stamped material blank. A cavity, wherein, on one hand, the at least one punch having pre-stamped the material blank and, on the other, at least one pair of electrodes are located, is filled with liquid. The pre-stamped material blank is placed in contact with the liquid of the cavity, and at least one electrical discharge is generated between the at least one pair of electrodes in such a way as to deform the pre-stamped material blank against the die.

  • Patent number: 11883867
    Abstract: The invention relates to a device for rolling, in particular for stepped rolling, of rolling stock with at least one pair of rolls and at least one linear drive arranged downstream of the pair of rolls in the rolling direction, which together with the pair of rolls can apply tensile stress to the rolling stock, and with means for detecting the tensile stress. In order to enable an improved method of flexibly rolling stock, the rolling device is characterized by means for detecting the tensile stress and by a control device for controlling the drive power of the linear drive as a function of the tensile stress detected, in order optionally to vary the tensile stress applied to the stock or to keep the tensile stress constant as the drive speeds behind the roll gap change. The invention also relates to a method of rolling the rolling stock using such a device.

  • Patent number: 11865600
    Abstract: A hollow preform impact extruded from a metal billet to produce a progressing wall at a transition wall thickness. An axially forward portion of the progressing wall is ironed by extrusion past an extrusion point to form a sidewall portion of a lesser thickness. Extruding is stopped while some of the billet remains to form the closed bottom end. The preform has a bottom portion, a sidewall portion and a transition wall portion extending between the bottom portion and the sidewall portion. The transition wall portion is thicker than the sidewall portion and can be formed into at least part of the rim of an expansion shaped container. An impact extrusion punch has a central axis, an axially forward, impact surface for impacting metal to be extruded, a transition region for directing material displaced by the impact surface and a rear extrusion point for ironing material extruded past the transition region.

  • Patent number: 11833562
    Abstract: Dual-stage multi-roll leveler embodiments of the general inventive concept include independent sets of first stage work rolls and second stage work rolls, with each set of work rolls including one or more upper work rolls disposed above one or more lower work rolls. An adjustable but equal entry side-to-exit side gap is present between the upper and lower work rolls of each work roll set. An exemplary dual-stage leveler removes shape defects and coil set and/or curl from a moving strip material through a combination of work roll gap adjustment and first and/or second stage work roll bending. Because there is no feathering out of work roll penetration in either stage, differential roll speed and the problems associated therewith are eliminated.
