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.
Claims9
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 a lamination (18) out of the sheet metal strip in a first position (20), wherein the lamination from the first position forms a stack of laminations,
- b) transporting the stack of laminations from the first positon into a second position (24) adjacent to the sheet metal strip (19) and applying at least one adhesive to an upper side of the stack of laminations in the second position,
- c) transporting the stack of laminations provided with the at least one adhesive from the second position (18) subsequently into a third position (25) underneath the sheet metal strip (19),
- d) punching a lamination (18) out of the sheet metal strip (19) in the third position (25) and placing the lamination from the third position under pressure onto the stack of laminations provided with the at least one adhesive in the third position (25) to add the lamination from the third position to the stack of laminations,
- e) transporting the stack of laminations from the third positon into a fourth position (26) adjacent to the sheet metal strip (19) and applying at least one adhesive onto an upper side of the stack of laminations in the fourth position,
- f) transporting the stack of laminations provided with the at least one adhesive from the fourth position subsequently into the first position (20) and punching out a lamination from the sheet metal strip in the first position and placing the lamination from the first position under pressure onto the stack of laminations provided with the at least one adhesive in the first position lying thereunder to add the lamination from the first position to the stack of laminations, and
- g) repeating steps b) through f) subsequently until the stack of laminations has a desired height.
