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 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.
