Abstract:
The present disclosure relates to a process for the blanking of metal parts (10; 11). According to the present disclosure a double layered basic material (51) with two preferably essentially identical, mutually stacked individual layers (50) is placed and clamped partly between a blanking die (80) and a blank holder (70) and partly between a blanking punch (30) and a counter punch (40) that are moved relative to the blanking die (80) and the blank holder (70) over a distance corresponding to at least a thickness of the double layered basic material (51) whereby two blanked parts (10; 11) are cut and separated from the double layered basic material (51).

The present disclosure relates to a process for the blanking of metal parts (10;11). According to the present disclosure a multi-layered basic material (51) with a number of mutually stacked, preferably essentially identical, individual layers (50) is placed and clamped partly between a blanking die (80) and a blank holder (70) and partly between a blanking punch (30) and a counter punch (40) and wherein the blanking punch (30) and the counter punch (40) that are moved relative to the blanking die (80) and the blank holder (70) over a distance corresponding to at least a thickness of the multi-layered basic material (51) whereby several blanked parts (10; 11) are cut and separated from the multi-layered basic material (51).
Abstract:
Embodiments of the present invention include methods and an apparatus to fabricate heat treated laminations (61) such as for high-speed rotors of electrical machines. A method, for example, includes heat treating a steel material, cutting a lamination pattern in the steel material to define a plurality of laminations (61), and bonding sets (31) of the plurality of steel laminations (61).
Abstract:
The invention relates to a heat treatment for the annealing of blanked metal parts (1; 10; 11), in particular of metal parts (1; 10; 11) obtained in a multi-layer blanking process from a multi-layered basic material (51) with a number of mutually stacked individual layers (50). According to the invention, the annealing heat treatment is limited to the cut surfaces (CS1) of the metal parts (1; 10; 11). In particular, the annealing heat treatment is limited to specific areas (SA1) of the cut surfaces (CS1) of the metal parts (1; 10; 11) where a functional magnetic field is present during use of the metal parts (1) in a lamination (3) of an electrical device.

Abstract:
A test/inspection apparatus (10) for dies for electrical use, in particular for dies for cutting magnetic metal plates adapted to be stacked or superimposed one on the other to define layered packs for use in electrical machines, comprising interaction means with special functions (20) or mechanical elements of a cutting die (21), which enable/disable one or more cutting elements of said die, said apparatus being coupled to the cutting die (21) for testing it off a cutting press.
Abstract:
Bleche (11, 12, 13, 21, 22, 23) werden verbunden, indem in Bleche (11, 12, 13) eines ersten Stapels (1) ein Loch (4) eingebracht wird, und ein Bereich (31, 32, 33) von Blechen (21, 22, 23) eines zweiten Stapels (2) in einer Stapelrichtung (110) verformt wird. Dabei kann sich der verformte Bereich (31, 32, 33) derart plastisch deformieren, dass eine Verspannung des verformten Bereichs (31, 32, 33) mit mindestens einem darunter liegenden Blech (11, 12, 13, 21, 22) entsteht. Vorzugsweise weist das Loch (4) eine Form mit mittig reduzierter Breite (41) auf.
Abstract:
The present invention relates to a process for the simultaneously blanking of metal parts from a multi-layered basic material (51) composed of a number of mutually stacked, preferably essentially identical, individual layers (50). Prior to such blanking of the metal parts, the multi-layered basic material (51) is provided with an interlock (1) by the local plastic deformation thereof between a press-locking punch (101) and an anvil (103), whereby the individual layers (50) are mutually fixated in all three spatial dimensions. According to the invention, the interlock (1) is provided to the multi-layered basic material (51) outside the (virtual) contour of the metal parts (10) to be blanked.
