Definitions
- the invention relates to a method for packaging at least 2 lamellae from a composite material by deepening and pressing the lamellae arranged one on top of the other, a lamellae package produced by this method and its use.
- Packing is the joining of individual layers, so-called lamellae, to a package.
- lamellae an ordered stack of slats arranged one on top of the other is formed, which are arranged so that they cannot be moved relative to one another.
- packaging is used in the manufacture of electric motors.
- stator and rotor lamellae are often punched out and packaged in a mechanically automated manner.
- the object of the present invention was to provide a simple packaging method which overcomes the disadvantages of the prior art.
- processes for processing thin electrical steel strips are to be made available.
- the possibility should be created to produce packages with the existing tools in order to avoid time-consuming changes in the process steps in the manufacturing process and in subsequent uses.
- the invention therefore relates to a method for packaging at least 2 lamellae from a composite material by deepening and pressing the lamellae arranged one on top of the other, since the composite material comprises a 1st and a 2nd electrical steel layer and a plastic layer arranged between them.
- the electrical steel layer is also referred to as electrical steel, electrical sheet or sheet metal.
- the plastic layer is also referred to as a polymer layer or polymer layer.

- the upper lamellae When packaging in the sense of the invention, the upper lamellae are deepened, ie an enforcement is generated by means of pressure from a stamp. As a result, at least one loading area of a lamella is pressed down, that is, moved into an underlying plane. The upper and the lower slat, possibly several slats, are pressed together. If necessary, enforcement is also generated by several slats.
- the penetration of a lamella has a depth that is greater than the thickness of an electrical steel layer. Preferably the same or at most essentially the thickness of a lamella. In another alternative, the depth of enforcement is less than the thickness of an electrical steel layer.
- enforcement has a depth in this alternative essentially 40%, 50% or more of the thickness of an electrical steel layer. Essentially, this means that there is a maximum deviation of 50%, 40%, 30%, preferably 20%, particularly preferably 10%, in particular 5%, 3%, 2% or 1% between two values.
- the packaging according to the invention takes place in a tool during a punching process and is also referred to as punch packaging.
- the present invention also relates to a method for stamping in a stamping step, that is to say a single stamping stroke of the composite material, which comprises a 1st and a 2nd electrical steel layer and an intermediate plastic layer, characterized in that the composite material is made available and
- punching is carried out in one punching step by means of a stamp and a die.
- the punching according to the invention is essentially based on the following steps or consists of:
- Breaking through the sheets that is also the at least one sheet arranged below it, which is not in direct contact with the punch;
- the lower sheet is cut less from the lower side through the die wall.
- the fraction is characterized in that here the separation of the sheet metal parts is usually occurs at the grain boundary, while grains of the metal structure are also cut and damaged in the cut portion and plastic deformations are introduced.
- top and bottom are also defined: top means stamp side and bottom means die side.
- top means stamp side and bottom means die side.
- the punched edge of the 2 sheets of the composite material have different ratios of the cut to fraction.
- the ratio of the cut to the fractional fraction in the respective punched edge in the upper plate is larger than in the lower plate.
- the lower sheet preferably has a fraction of at least 30%, 40%, 50%, 52%, 54%, 56%, 58%, particularly preferably 60%, 61%, 62%, 63%, 64%, in particular 65% , 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75% or more.
- the ratio of cut to breakage is determined by determining the height of the cut area and the height of the breakage area on the punched edge on the basis of grain damage, for example using a microscope, and comparing them to one another.
- a lamella in the sense of the invention is a semi-finished product which emerges directly from a stamping process without any further work step.
- a cutting process in particular shear cutting, is referred to as punching, which is carried out by means of a punch and a die; if necessary, further aids such as guides, holders, wipers, etc., which do not directly intervene in the cutting process of the sheet, are used.
- the composite material is available as a starting material in the form of coils or boards.
- the individual slats are stacked on top of one another before being packaged.
- the lamella can have a complicated outline. This is characterized by a self-contained polyline, which represents a coherent sequence of line segments, with at least 2 straight line segments of different lengths and, if appropriate, at least one curved line segment or combinations thereof.
- the semi-finished products have a relatively large area as an additional feature, preferably an area larger than 15 cm 2 , 20 cm 2 25 cm 2 , particularly preferably larger than 40 cm 2 , 50 cm 2 , in particular 75 cm 2 or 100 cm 2 and preferably smaller than 10,000 cm 2 , particularly preferably smaller 1000 cm 2 , in particular smaller 500 cm 2 , 250 cm 2 , 200 cm 2 .

- the composite material has a minimum yield strength in the longitudinal direction at room temperature of 310 to 510 MPa and a maximum tensile strength of 400 to 640 MPa and a minimum elongation at break A80 of 7 to 32% measured in accordance with DIN EN ISO 6892-1 and one Hardness Hv5 from 130 - 250.
- the material has an anisotropy at PI, 0; 400 Hz in the range from 6 to 17%.

- the composite material By using the composite material, not only can the structure-borne noise in the electric motor be significantly reduced, but also, for example, by varying the thickness of the electrical steel sheet used, either a further cost advantage and / or an increased efficiency of the electric motor or generator can be generated.
- the composite prevents and / or dampens the vibrations generated at their source. This prevents transmission to the housing and neighboring components.
- the structure-borne sound generated by the electric motor but also the air sound generated by the housing is significantly reduced. As a result, there is a reduction in the acoustic emission of the entire electric motor.
- the specific magnetic reversal losses of electrical steel sheets depend very much on the thicknesses or the cross section of the sheets used. As a rule, the smaller the layer thickness of the electrical steel, the lower the eddy current losses and thus the specific magnetic losses. In particular at high electrical frequencies, the magnetic reversal losses increase disproportionately.
- two electrical strips of the same quality with a thickness of 0.25 mm can be glued together compared to a monolithic electrical steel strip with a thickness of, for example, 0.5 mm. In relation to an engine type, this can either significantly increase the efficiency of the engine or enable the construction of a smaller engine with the same efficiency. The latter would bring a weight advantage. Furthermore, the use of an electrical tape of lower quality is also possible.
- the composite materials themselves, as well as the components made from them come into contact with various, sometimes very aggressive, oils that can attack the polymer layer and thus lead to damage to the polymer layer and even delamination. It is therefore desirable that the polymeric layer is resistant to such industrial oils.
