  • Patent number: 11020784
    Abstract: A method for producing a molded body of particularly steel, and including a hub and a bell-shaped lower part axially connected thereto, in which an inner contour is made in the lower part by non-cutting forming in a convex region. The inner contour includes of ball tracks and cage paths that are concave in the axial direction and arranged in a peripherally alternating manner, for receiving rolling bodies, the cage paths being shallower than the ball tracks. The hub is formed from a rotating round blank and reducing the thickness thereof using at least one pressure roller. The flat region of the round blank that radially connects to the hub is pressed onto contour segments of a rotating first inner contour tool, partially forming the inner contour using at least one axially and radially moving pressure roller to form a preform of the lower part. The fixed preform is pressed against contour segments of a second inner contour tool by a die of partial dies, fully forming the cage paths and ball tracks.

  • Patent number: 8495900
    Abstract: The device for satinizing and embossing packaging foils comprises at least two embossing rollers that are each provided with a toothing consisting of individual teeth, the pyramidal teeth having an essentially rectangular horizontal projection, and the sides of the teeth being essentially parallel and perpendicular, respectively, to the longitudinal axis of the embossing roller. In contrast to the prior art, the opening angle (?) between the radially aligned adjacent tooth flanks is smaller than the opening angle (?) between the axially aligned adjacent tooth flanks, and the tooth height in the radial direction, measured from the tooth tip to the tooth bottom, is greater than the tooth height in the axial direction measured from the tooth tip to the tooth bottom. This dimensioning and arrangement of the teeth provides an improved gearing with a reduced specific pressure as well as an improved processing of the paper part of the foil that results in its better folding, curling, and tubing behavior.

  • Publication number: 20120272703
    Abstract: The invention relates to a method for rolling strip-shaped rolling stock, in particular metal strip. This method is characterised substantially by the following procedure: the metal strip A exiting the pickling line passes through the two roll stands (3, 4) of the reversing roll stand, wherein the start of a subsequent metal strip B has already been welded to the strip end of the metal strip A before entering the pickling line (5), said start of the metal strip B is then rolled as well, specifically over a length corresponding to the wind-on length until tension is built up on the reel and likewise rims on the reversing reel (1), during the subsequent reversing the metal strip B is separated from the metal strip A such that the already rolled start of the metal strip B remains on the still unrolled remaining metal strip B, then the complete metal strip A is reverse-rolled.

    Abstract: There is provided a production method capable of forming spiral ribs stably by reducing troubles at the time of cold drawing for forming the spiral ribs on an internally ribbed steel tube. When the internally ribbed steel tube on which a plurality of stripes of spiral ribs are formed in the tube axis direction is manufactured by inserting a plug on which a plurality of stripes of spiral grooves are formed on the outer peripheral surface thereof into the tube to be worked subjected to chemical treatment and then performing cold drawing, drawing is performed with the plug preheated to 50 to 200° C., thus forming the spiral ribs on the internal surface of a blank tube. The chemical treatment preferably includes a pickling step of removing oxided scale and rust on the tube surface, a step of forming a zinc phosphate coat on the neutralized tube surface, and a step of forming a lubricating layer on the zinc phosphate coat.
