Embodiment Construction

[0027] according to figure 1 The exemplary embodiment in FIG. 2 schematically shows a device 1 for carrying out the method or the stacking process according to the invention, in particular the stamping stacking process. The equipment 1 is used for stacking the punched out plate parts 2 into a plate group 3, the plate group according to figure 1 Further transport from the plant 1 is carried out by means of the conveyor belt 4 .

[0028] For this method, an electrical steel strip 6 is uncoiled from a reel 5 and has a polymerized adhesive layer over the entire surface, ie a thermally cured baking varnish, on both strip sides 7 , 8 . Sheet metal parts 2 are punched out of the bake-coated electrical steel strip 6 by means of a punching tool 9 designed as a sequential punching tool. This blanking can be (as is generally referred to) cutting, cutting off, breaking off, trimming, breaking off by pressing out, etc.

[0029] so external figure 1 It is known that the stamping tool 9 ...

Abstract

A device (1) and a method for connecting lamination parts (2) to form lamination stacks (3) are presented, in which lamination parts (2) are punched out of an electrical steel strip (6) by means of atleast one punching stage (17) which has a die (15) and a cutting edge (13) which interacts with the die (15), the punched-out lamination parts (2) are stacked and are at least cohesively connected toform multiple lamination stacks (3), wherein a separating element (22) is provided between at least one first lamination part (102) of the stacked lamination parts (2) and the following second lamination part (103) of the stacked lamination parts (2) in order to facilitate the separation of the cohesively connected lamination parts (2) into lamination stacks (3). To improve the reproducibility ofthe method with regard to the application of the separating element, it is proposed that, after the punching-out of the first lamination part (102) and before the punching-out of the second lamination part (103), the separating element (22), which, in accordance with the die geometry, is of smaller or identical form, is led to the die (15), is introduced into said die (15) and is thus provided onthe first lamination part (102).

Description

technical field [0001] The invention relates to a device and a method for joining sheet metal parts into a sheet metal group, wherein the sheet metal parts are punched out of an electrical steel strip by means of at least one stamping stage with a die and a cutting edge cooperating with the die. The punched sheet metal parts are stacked and at least materially bonded (stoffschlüssig) connected to form a plurality of sheet metal groups, wherein at least the first sheet metal part of the stacked sheet metal parts and the next second of the stacked sheet metal parts Separating elements are arranged between the second sheet-metal parts of a sheet-metal part in order to facilitate the separation of the integrally connected sheet-metal parts into sheet-metal groups. Background technique [0002] In order to be able to separate the pre-bonded or self-finally bonded sheet-metal parts into sheet-metal groups when punching the stack, it is known from the prior art (WO 2014 / 089593 A1) ...
