  • Patent number: 8240184
    Abstract: 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.

  • Patent number: 8042368
    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.

  • Publication number: 20110200766
    Abstract: A hollow profile that has improved handling ability and a good ability to be attached to other components and a method for producing the hollow profile. In the method for producing a hollow profile having at least two half shell sheets, a first half shell sheet is applied to a first side of web plate along two axially running joint edges of the first half shell sheet, a second half shell sheet is applied to a second side of the web plate along two axially running joint edges of the second half shell sheet, and then the joint edges of the half shell sheets are subsequently joined to the web plate. An edge section of the web plate projects beyond the contact area of at least one joint edge so that at least one flange is formed for attaching other components. The hollow profile formed has two half shell sheets and a web plate disposed between the half shell sheets, which can form part of a vehicle body.

  • Publication number: 20110094283
    Abstract: 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.
