Abstract: A device for producing at least partly closed profiles from a blank includes at least one first die and at least one second die which can be positioned opposite the first die. The first die has a cavity and two side walls, wherein the side walls and the cavity of the first die can be raised and lowered relative to one another. A U-punch is provided to produce a U-shaped cross-sectional shape of the blank with the first die. The second die of the device has a cavity for producing an at least partly closed cross-sectional shape from a U-shaped blank. The device also has at least one supporting core. The cavity of the second die has elongated side walls in the direction of the first die, with which, the side walls of the first die can be lowered relative to the cavity of the first die.

Abstract: The invention relates to a method for producing hollow profile-members having a longitudinal flange, wherein a plate which is arranged between the stamp and the first die being preshaped by introducing a stamp into a first die to form an U-shaped profile-member having a first member and a second member, and wherein the U-shaped profile-member being shaped with a second die to form an O-shaped profile-member having a longitudinal flange. In one aspect, the plate is preshaped to form the U-shaped profile-member, a longitudinal flange member portion is shaped in at least the first member and the longitudinal flange member portion is constructed during the shaping of the U-shaped profile-member to form an O-shaped profile-member substantially in a shape-retaining manner to form a portion of the longitudinal flange.

Abstract: A device for manufacturing profiles from a sheet includes at least one work station with a base plate and two die halves, wherein the die halves and the base plate extend in the longitudinal direction of the profile to be manufactured, and the die halves are arranged on the base plate movable relative to one another perpendicular to the longitudinal direction of the profile. A generic device and method for manufacturing profiles with which even heavily structured profiles can be economically produced with high flexibility, is provided by a punch for forming the sheet. The punch is movable perpendicular to the relative movement of the die halves and perpendicular to the longitudinal extension of the profile to be manufactured. The base plate has a die adapted to the punch, in which the sheet is formed, and the die of the base plate and the punch pertaining to it are exchangeable.

Abstract: A supporting core for using in a device for forming plates into a structured hollow profile and a method for producing structured hollow profiles from a plate, which on the one hand ensures an all-over support of the plate, and still enables the production of hollow profiles with a variable cross-section or a curved course, is provided by including individual supporting members, which when pushed together at least in part form as a surface an inner contour of the hollow profile to be produced and are interconnected by means of coupling elements, wherein the coupling elements allow the supporting members to be pulled-apart, and wherein the supporting members are interconnected in a hinged manner in the pulled-apart position.

Abstract: To produce hollow profiles from sheet-metal blanks, the invention uses at least two process steps to form said blanks into a slit profile which is subsequently welded to produce the finished welded profile. For this purpose a mandrel is used which cooperates with a first tool part in the first step, and with a second tool part in the second step, such as to form a gap with the recess of each tool part into which a portion of the sheet-metal blank is guided. Shaping the sheet-metal blank in at least two steps means that a mandrel that is a self-contained component and can therefore be moved by a simple control device can be used to support the sheet-metal blank while the slit profile is being created. This considerably reduces the equipment needed to produce the hollow profile. Moreover, forming the sheet-metal blank into the slit profile in at least two steps also considerably improves the reliability with which this shaping takes place.

Abstract: A method for producing a longitudinally welded hollow profile from a sheet metal blank having defined longitudinal edges, in which the sheet metal blank is initially preformed into an open seam profile with the aid of at least two tool parts allows for the economical production of accurately formed hollow profiles. This is achieved in that to produce the open seam profile, the sheet metal blank, by a change in the relative position of the tools parts, is placed freely around a mandrel positioned between the tool parts and extending in the longitudinal direction of the sheet metal blank, the outer shape of which mandrel determines the inner shape of the hollow profile to be produced, and in that the shaping of the open seam profile obtained is then completed in one or more stages in each case by a further change of the relative position of the tool parts.
