Method for the production of a stack of laminations
In a method for manufacturing lamination stacks of controlled height in a tool, starting material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.

Method for the production of a stack of laminations
In a method for manufacturing lamination stacks of controlled height in a tool, starting, material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.

A method and tool for producing workpieces with small corner radii in relation to the cutting thickness and with greatly reduced draw-in by precision cutting in a precision cutting tool includes clamping the workpieces between two tool parts consisting of a respective top and bottom cutting dies and of a top and a bottom cutting punch. The workpiece is machined in a one-stage arrangement in at least two successive cutting sequences in different cutting directions with the following partial steps: (A) cutting out a semifinished product, matched to the workpiece geometry, in a first cutting operation in a vertical working direction with slight draw-in, and (B) finish cutting of the semifinished product, produced in step (A), in at least one further cutting operation in a working direction opposed to step (A), wherein the draw-in of partial step (A) is filled again at least in the corner region.
A method for the reinforcement of a wall region of a three-dimensional attachment for high torque loads, wherein, a plate with a substantially evenly curved outer contour is cut out of a flat strip and the plate is formed and fine blanked into a pot-shaped body with projections and/or impressions and/or indentations and/or recesses and/or sinks and/or holes and/or pivots by a forming and fine blanking tool including die, counter-die, die plate, V-shaped projection and pressure plate, whereby a circular edge for a toothing is formed at the body. Hinge attachments with a much higher safety with regard to fracture of the wall region between the edge with an inner toothing and the pot-shaped body of the hinge attachment are producible in a cost-effective way. The thickness of the wall region between the edge and the pot-shaped body of the attachment by a purposeful material shifting with at least a two-staged cold-extrusion process in respectively opposite flow directions angular to the die movement is reinforced in such manner that the purposeful material shifting in the wall region approximately equalizes the runoff of material caused by the forming.
