Definitions

  • the invention relates to a method for producing a lamellae consisting of superimposed lamellas according to the preamble of claim 1 and to an apparatus for carrying out such a method according to the preamble of claim 12.
  • the invention has the object of providing the generic method and the generic device in such a way that the slats can be reliably connected to each other regardless of the starting material and the stack density within the disk pack.
  • the lamellae can be firmly joined together in a simple, cost-saving manner, regardless of the material composition of the lamellae.
  • the material of the lamellae at the edge area is plastified locally by using the tool to locally heat the lamella so much that the lamellar material is plasticized. Then this plasticized material can be mixed by means of the tool between adjacent lamellae. This has the consequence that after the cooling of the plasticized material, the slat len firmly cohesively connected to each other.
  • the tool itself is chosen so that it is not soft or plasticized in this process itself. If the fins are made of silicon-aluminum strips, then the silicon content can be so high that the magnetic losses are low.
  • a simple and secure connection of the slats within the disk pack is obtained in an advantageous manner when the tool is moved over the height of the disk pack and is pressed with such a high force against the disk pack that the material of the slats is plasticized in the contact area with the tool .
  • the tool can be adapted with regard to the width of the weld seam which forms on the circumference of the disk pack. If this weld is to have only very small width, a correspondingly narrow tool is used. With the height and / or the duration of the contact pressure can be determined how deep the material of the slats is plasticized in the implementation of the method.
  • the tool is advantageously rotatably driven during one of the feed movement about its axis.
  • the plasticized material of adjacent lamellae is mixed together in a simple manner.
  • the tool is moved in the axial direction along the disk pack.
  • a weld seam extending in the axial direction is also produced on the disk pack.
  • the tool can also be moved at an angle obliquely over the height of the disk set, so that the resulting weld no longer runs axially, but has a slope.
  • the tool is stationary and is rotatably driven about its axis.
  • the disk pack is moved over its height relative to the stationary tool and in this case pressed with such a high force against the tool that the material of the blades is plasticized in the contact area.
  • the tool can be adapted with regard to the width of the weld seam forming on the circumference of the disk pack.
  • the feed motion of the tool can be very easily programmed via a controller.
  • a simple and time-saving method of operation results when the disc pack is processed with two or more tools.
  • the tools advantageously work simultaneously on the disk set, so that over the circumference of the disk set the required welds can be attached to the desired extent.
  • the tools are independently drivable. This makes it possible to selectively control the individual tools and, for example, to give them different feed paths.
  • the tools can also be provided within a stacking device, in which the lamellae are stacked to form the disk set.
  • the device according to the invention is characterized in that the at least one welding tool is rotatably driven about its axis and can be moved transversely to this axis of rotation during machining. During its feed movement, the tool is rotatably driven about its axis, whereby the high, required for plasticizing the fin material frictional heat is generated in the slats.
  • the tool is provided with an outer head which is rotatably driven about its axis.
  • an outer head which is rotatably driven about its axis.
  • a gear or a belt drive can be provided.
  • a center head is advantageously housed, which is rotatably or freely rotatably connected to the outer head.
  • the center head is taken by the rotating outer head.
  • the center head is adjustable in the axial direction of the outer head relative to the outer head and preferably rotatable.
  • This adjustment is achieved in a preferred embodiment by means of a spindle drive, through which the center head can be adjusted relative to the outer head.
  • a compact design of the tool results when the outer head and the center head are coaxial with each other.
  • FIG. 1 is a schematic representation in side view of an inventive device for punching lamellae to form a disk set
  • FIG. 3 is a schematic side view of a two-head friction stir tool
  • FIG. 6 shows the friction-stir tools and the disk pack according to FIG. 5 in FIG.
  • Fig. 7 is a plan view of a disk pack, the lamellas through
  • Friction stir welding are connected to each other,
  • FIG. 8 the disk pack of FIG. 7 in side view.
  • slats 2 (FIG. 8) are cut in a known manner from a metal strip (electrical strip) 1 or an electrical sheet, which are stacked to form a plate pack 3.
  • the disk set 3 is used for the production of rotors or stators of electric motors or generators.
  • the metal strip 1 is wound on a reel 4 which is rotatable about its axis.
  • the unwound from the reel 4 metal strip 1 is passed through a straightening apparatus 5, through which the metal strip 1 is directed for the subsequent punching process.
  • the metal strip 1 passes after the straightening apparatus 5 in a punch press 6, in which from the metal strip 1, the slats 2 are punched.
  • two or more bands 1 can be performed side by side, so that simultaneously from the individual metal bands 1, the slats 2 can be punched. Further, it is possible to punch the lamellae in the metal strip 1 not only in one lane, but also, for example, in two lanes.
  • the punch press 6 is provided with one or more corresponding punching tools 7.
  • the slats 2 stamped with them enter a shaft 8 into which the slats 2 are pressed immediately after punching.
  • the shaft 8 forms a receptacle and is formed in a known manner so that the slats 2 abut with its edge under friction on the inner wall of the shaft 8, so that they do not fall out of the shaft 8.
  • the punched fins 2 are set to a stack in the shaft 8.
  • the respective punched lamella 2 is pressed down onto the lamellae already located in the shaft.
  • Into the shaft 8 protrudes a (not shown) stamp on which the slats 2 are stacked to the disk pack 3.
  • the stamp is gradually moved down so that the respective punched lamella 2 are moved so far down into the shaft 8 can that the subsequent slat to be punched 2 can be reliably pressed into the slot 8.
  • each metal strip 1 is assigned a shaft 8, so that a plurality of plate packs can be stacked next to one another in the punching press 6 at the same time.
  • a transport device such as a rotary unit, promoted in the area above the shaft 8 and then pressed into the shaft 8 .
  • Such a transport device is particularly advantageous if the lamellae 2 are punched out of a metal strip 1 in adjacent tracks. Then the adjacent slats 2 can be transported with such a transport unit in the single shaft 8.
  • the slats 2 lying on top of one another in the disk pack 3 are firmly connected to one another.
  • the overlapping lamellae 2 are connected to each other transversely to their plane by a plasticizing process by partially plasticizing the lamellas 2 at the edge such that overlapping lamellae 2 are firmly bonded to one another after cooling of this material.

  • a radial annular shoulder 13 is formed at the transition between the center head 12 and the outer head 1 1, a radial annular shoulder 13 is formed.
  • the tool 9 ' is moved radially against the disk pack 3 until its end face 14 comes into contact with the jacket 15 of the disk pack.
  • the tool 9 ' is pressed with high axial force against the disk pack 3, wherein it is rotatably driven about its axis. Due to the friction between the flat end face 14 of the tool 9 'and the disk set 3, the material under the end face 14 heats up to just below the melting point of the material of the disk set 3. Due to this high temperature, the material of the disk set 3 is plasticized.
  • the rotating tool 9 ' is now moved in the height direction of the disk set 3, wherein the high axial force and the rotational speed are maintained.
  • the mixing movement of the tool results in a mixing of the tool Materials of superimposed slats 3 instead.
  • the material mixing is due to the fact that the tool 9 'carries out the feed movement with simultaneous rotational movement.
  • the feed rate is chosen so that in the region of the tool 9 ', the material of the superimposed slats 2 is soft. Due to the rotational movement, the materials of the overlapping lamellae 2 mix, so that after cooling of the plasticized material, the lamellae 2 within the lamella packet 3 are materially interconnected.
