Abstract
In a method for producing stacks of laminations, in which at least one adhesive is applied onto annular laminations with at least one application head and laminations are stacked into a stack of laminations, the lamination is rotated about its axis in the application area of the application head and/or the application head is moved about the axis of the lamination in order to apply the adhesive onto the lamination. A system for carrying out the method features at least one punching tool, with which laminations are punched out of a sheet metal material, wherein at least one station for cleaning and/or for activating and/or for applying an adhesive onto the laminations is arranged downstream of the punching tool.
Claims14
A method for producing stacks of laminations, in which the laminations are punched out of a sheet metal strip and at least one adhesive is applied onto the laminations with at least one application head, wherein the laminations provided with the at least one adhesive are stacked into a stack of laminations, the method comprising:
- a) punching the lamination (18) out in a first position (20),
- b) transporting the lamination (18) into a second position (24) adjacent to the sheet metal strip (19), in which the at least one adhesive is applied,
- c) transporting the lamination (18) subsequently into a third position (25) underneath the sheet metal strip (19),
- d) punching the next lamination (18) out of the sheet metal strip (19) at the height of the third position (25) and placing the next lamination under pressure onto the lamination (18) provided with the at least one adhesive in the third position (25),
- e) transporting the thusly created partial stack into a fourth position (26) adjacent to the sheet metal strip (19), in which the at least one adhesive is supplied onto the partial stack,
- f) transporting the partial stack subsequently into the first position (20), in which the next lamination (18) is punched out and placed under pressure onto the partial stack lying thereunder, and
- g) repeating steps a) through f) subsequently until the stack of lamination has the desired height.
A system for carrying out a method for producing stacks of laminations, in which at least one adhesive is applied onto annular laminations with at least one application head and laminations are stacked into a stack of laminations, the method comprising:
- rotating the lamination (5, 6) about its axis (17) in the application area of the application head (7) and/or moving the application head (7) about the axis (17) of the lamination (5, 6) in order to apply the adhesive;
- wherein the system features at least one punching tool, with which laminations are punched out of a sheet metal material,
- wherein the system is characterized in that at least one station (4a, 8, 9) for cleaning and/or for activating and/or for applying the at least one adhesive onto the laminations (5, 6, 18) is arranged downstream of the punching tool (4).
