A method for profiling a profile body by cold forming a workpiece having a longitudinal axis and a cylindrical outer surface extended along the longitudinal axis. The workpiece carries out a rotation movement about the longitudinal axis and is machined by a tool in a multitude of successively executed reshaping engagements. The tool is held by a tool holder, to be rotatable about a tool axis. The tool holder is mounted in an orbiting body to be rotatable about a rotation axis, is driven into a rotation movement about its rotation axis, and is driven into an orbiting movement by the orbiting body. Rotation movement of the workpiece is synchronised with orbiting movement of the tool holder and rotation movement of the tool holder is synchronised with orbiting movement of the tool holder. The tool axis is different from the rotation axis.

The present invention relates to a forge rolling device (1) for the bending forge rolling of a component (2), in particular of a component blank, having a first forging roll (10) with a first axis of rotation (R), and a second forging roll with a second axis of rotation, wherein each of the forging rolls (10) has, on its surface (11), a forge rolling contour (12) that runs at least partially around its axis of rotation (R), said forge rolling contours (12) corresponding to one another, in order to form a component (2) passed between the forging rolls (10) in a passage direction (D). This forming can be bending with or without cross-sectional change. In this case, the forge rolling contours (12) are configured so as to bend the component (2), passed between the forging rolls (10), in at least one direction transversely to the passage direction (D) of the component (2), at least by means of one subregion (13) of the forge rolling contours (12). The present invention also relates to a method for the bending forge rolling of a component (2) and to a component (2) produced with the method according to the invention.

The present invention relates to a device for forming a round bar into variable shapes, comprising: a main body provided with a plate portion with a circular shape having a plate hole formed in a center thereof, having plate protrusions protruding to the plate portion in a radial shape, and a turn gear connecting portion formed at an outer circumference surface of the plate portion; a round bar forming portion coupled between the plate protrusions and having a slide mold seated on the plate portion and a forming roll coupled to the slide mold to rotate; and a turn gear having a donut shape, provided with a turn gear protruding portion with a circular arc shape having different diameters from a center in an inner surface thereof, and disposed between the slide mold and the turn gear connecting portion.

A method to improve the collapse resistance of metallic tubular products is disclosed. The method comprises identifying the types of stress that can be applied in order to change the residual stress profile of metallic tubular products, such as those that have completed a straightening process, and results in a residual stress profile that improves collapse resistance. The metallic tubular product is subjected to radial compression processing to control the residual stress profile and to enhance collapse resistance. The radial compression process may be used after the tubular product has been subjected to a straightening process.

A method of reshaping a cylindrical pipe to a ground screw foundation for attaching an object to the ground includes a drawing unit and a working tool having a plurality of press roll disks or press roll disk segments. The press roll disks or press roll disk segments are disposed radially around a longitudinal axis of a holder for the cylindrical pipe, and pivotably around shafts extending at a fixed distance to the longitudinal axis transversely and tangentially relative to the longitudinal axis. A cylindrical pipe is inserted into a holder. The cylindrical pipe or the working tool with the drawing unit is drawn such that a relative movement between the pipe and the working tool is created.

A method for producing an internally and/or externally toothed pot-shaped sheet metal part having teeth extending toward the pot center axis, wherein an un-toothed pot-shaped sheet metal part is inserted into a die and then, by means of a relative movement between the sheet metal part and associated profile rollers, a profile is rolled onto the pot-shaped sheet metal part by the profile rollers applied to the sheet metal part and thus alternating internal and external gear teeth are applied to the sheet metal part, wherein the profile rollers form the sheet metal part oriented radially from the inside toward the outside, in that the profile rollers roll along the inner circumference of the sheet metal part.

To minimize the setup times in the case of a tool changeover on rolls, the movement sequences are separated into transverse movements and vertical movements using a tool changeover system and method for changeover of at least one tool disposed on a roll shaft in a working position. In one aspect, the tool changeover system includes a tool changeover rack, a vertical transport and a transverse transport. A drawing frame separate from the tool changeover rack can be transported transversely separately with reference to the tool changeover rack. The tool changeover rack has a device for connecting with the vertical transport and a tool accommodation for accommodating the tool. The drawing frame has a device for connecting with the transverse transport and a device for connecting with the tool.

A workpiece executes a rotation movement about a longitudinal axis and is machined by a tool in a multitude of reshaping engagements, in which an active region of the tool comes into contact with the machining region. The tool is held by a tool holder. The tool holder is mounted in an orbiting body so as to be rotatable about a rotation axis and is driven to carry out a rotating movement about the rotation axis, and is driven to carry out an orbiting movement by the orbiting body. Rotation movement of the workpiece is synchronised with the orbiting movement of the tool holder and the rotating movement of the first tool holder is synchronised with the orbiting movement of the tool holder.
