摘要： A method for producing highly dimensionally accurate, deep-drawn half shells with a base region, a body region and a flange region, includes firstly forming a pre-formed half shell from a blank and then shaping the pre-formed half shell into a finally formed half shell, wherein the pre-formed half shell has excess blank material due to its geometric shape and wherein, owing to the excess material during the shaping of the pre-formed half shell into its final shape the half shell is compressed into the finally formed half shell by at least one further pressing process. The method requires that the pre-formed half shell has excess blank material in a transition region between the body region and flange region.

摘要： A method for producing low-springback half shells made of a metal, in particular steel or a steel alloy, includes drawing in at least one drawing die a blank, such that the blanks have flange regions on the deep drawn body after the deep drawing. The flange regions are shaped by upsetting a corner substantially perpendicularly to a wall of the deep drawn region of the blank and the flange regions are subsequently trimmed in a shearing die, such that half shells without margins are produced.

摘要： A method for converting blanks by drawing in a tool with a ram, a die and a pressure pad wherein, converted blanks with high dimensional precision can be produced, includes feeding a blank with a plurality of bulges to the tool. In flange regions of the blank the pressure pad is moved in a first process step of the method into a first position, which corresponds to the height of the bulges of the flange region of the blank added to the blank thickness. In the first process step the blank is preformed in the tool using the ram and in a second process step the pressure pad and the ram are moved into the end positions, so that the blank is converted by the ram to the end form and the pressure pad smoothes the bulges of the flange regions of the blank.

摘要： The aim of the invention is to provide a method for controlling the flow of material when deep-drawing a workpiece, which better utilizes the drawing capacity of a workpiece and produces a better shape accuracy, particularly of the bottom of the drawn part. The aim is achieved by a method in which the deep-drawing process is performed incrementally and in which at least one bead is incorporated into the flange region of the workpiece prior to each increment of the deep-drawing process. Due to this, the shape accuracy of the bottom can be improved and material accumulations in the flange zone can be prevented.

摘要： 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.

摘要： A method for manufacturing a sheet metal blank, in particular a tailored blank, in which at least two metal sheets are connected to one another at their respective connecting edges, the two metal sheets displaying differing thickness is provided herein and allows in a simple manner an application-specific configuration of the region of transition from one metal sheet thickness to another metal sheet thickness. The method includes a step in which, prior to the connecting of the two metal sheets, at least the region of the connecting edge of the thicker of the two metal sheets is pressed to a predefinable thickness in a forming tool in such a way that the connecting edges of the metal sheets display substantially the same thickness.
