PROCESS FOR MANUFACTURING A LAMINATE OF STACKED METAL PARTS INCLUDING A MULTI-LAYER BLANKING PROCESS STEP

The invention relates to a process for manufacturing a laminate (17) from a number of sets (16; 16-1, 16-2, 16-s) of metal parts including a multi-layer blanking process step for cutting these sets (16; 16-1, 16-2, 16-s) from a layered basic material, whereof the constituent layers are interlocked by the local plastic deformation thereof inside the contour of the metal parts to be cut and whereby a bulge (4) is formed on the layered basic material and on the metal parts that are cut therefrom. According to the invention, in the multi-layer blanking process step, the sets (16; 16-1, 16- 2, 16-s) of metal parts are each provided with a hole (15) for receiving the bulge (4) of an adjacent set (16; 16-1, 16-2, 16-s) of metal parts in the laminate (17). 本发明涉及一种用于从多组(16；16-1、16-2、16-s)金属部件制造叠层(17)的方法，包括用于从层叠基材切割这些组(16；16-1、16-2、16-s)的多层冲裁工艺步骤，组成层通过其在待切割金属部件的轮廓内的局部塑性变形而互锁，并由此在层叠基材和从其切割的金属部件上形成隆起(4)。根据本发明，在多层冲裁工艺步骤中，金属部件的组(16；16-1、16-2、16-s)分别设置有用于接收叠层(17)中金属部件的相邻组(16；16-1、16-2、16-s)的隆起(4)的孔(15)。
