The invention relates to a method and a device for producing a body of sheet metal stacks, said method comprising the following steps: a stack is first formed in a cavity (1) of a tool from several sheet metal parts (3) which have an identical contour in at least one area, wherein thermally curing adhesive layers are provided between the sheet metal parts (3). Subsequently, the sheet metal parts (3) are heated in order to cure the adhesive layers and to form the body of sheet metal stacks. The contour of the cavity (1) of the tool is in at least one part of the area of the identical contour of the sheet metal parts (3) exactly fitting with the contour of the sheet metal parts (3). Due to the material contact in this area and during heating of the sheet metal parts (3), a predominant part of the energy required for heating is introduced into each single sheet metal part (3) by means of the tool, thereby causing the curing of the adhesive layers. Advantageously, the sheet metal parts (3) are produced by punching and are introduced into the cavity (1) against frictional resistance between the tool and the sheet metal part (3). A first fluid is in particular fed into the tool in order to introduce thermal energy into the tool, which is in turn introduced into the sheet metal parts (3). |
