Description

[0001] Method for processing a workpiece

[0002] The present invention relates to the processing of a workpiece by punching and / or cutting between two tools that rotate about tool axes that are preferably parallel to each other. It relates in particular to the technical field of electric drives, especially the efficient production of high-performance electric drives.

[0003] Vehicles, especially land vehicles, aircraft and watercraft, are increasingly being powered entirely or partially by electricity.

[0004] Efficient electric drives are therefore becoming increasingly important.

[0005] The present invention is based on the objective of providing a component for an efficient electric drive, in particular of a vehicle, and / or a vehicle comprising the component, with the least possible effort; providing a method for manufacturing a component for an efficient electric drive, in particular of a vehicle, whereby this component can be provided with the least possible effort; and / or providing a processing means for manufacturing a component for an efficient electric drive, in particular of a vehicle, whereby this component can be provided with the least possible effort.

[0006] In particular, the component should be able to be provided with minimal effort, e.g. with regard to the required production equipment and / or production speed, and / or in good quality.

[0007] The component for an efficient electric drive can be, for example: an electric machine, wherein the electric machine can be, for example, an axial flux motor, a rotor arrangement, a stator arrangement, a coil arrangement, a coil device, a form element package, wherein the form element package can in particular be a form element package for a magnetic core, and a form element, wherein the form element can in particular be a form element for manufacturing a form element package for a magnetic core.

[0008] The processing equipment for manufacturing a component for an efficient electric drive can be, for example: a machining system, a tool arrangement, a tool, a machining unit and a machining counter unit.

[0009] The problem is solved according to the invention by the method for processing a workpiece in accordance with the relevant independent claim.

[0010] The method is a method for machining a workpiece, wherein the machining of the workpiece takes place between two tools which rotate about tool axes which preferably run parallel to each other, one of the two tools has a machining unit and the other of the two tools has a counter-machining unit, wherein the machining unit and the counter-machining unit together form a punching arrangement and / or cutting arrangement, and the machining of the workpiece in the punching arrangement and / or cutting arrangement is carried out by punching and / or cutting along a separation line defined by the punching arrangement and / or cutting arrangement such that a shaped element is formed and is incompletely or completely separated from the workpiece.

[0011] The process is not only suitable for manufacturing a component for an efficient electric drive. It is also particularly suitable for providing sheet metal for a wide variety of applications, e.g., for cylinder head gaskets. When a forming element is mentioned herein, this can refer in particular to a sheet metal forming element. The forming element, e.g., sheet metal forming element, can advantageously be a forming element for manufacturing a forming element package for a magnetic core, a battery cell housing element, in particular a battery cover element, a bipolar plate element and / or separator plate element for an electrochemical system, e.g., for a fuel cell system or an electrolysis system, a gasket or a component of a gasket, in particular a cylinder head gasket or a component of a cylinder head gasket, or a temperature control plate, e.g., a cooling plate, for example, for a plate heat exchanger.

[0012] It was found that the processing method according to the invention significantly reduces energy consumption and simultaneously increases processing speed considerably. Sheet metal is usually processed or stamped in presses, where large masses are moved for each individual processing or stamping operation. The energy required for this can be saved by the invention. Overall, approximately 95% of the energy required for stamping in a press can be saved, while at the same time the processing speed can be increased many times over.

[0013] The separation can be complete or incomplete.

[0014] For example, at least during punching and / or cutting, one or more bridges and / or predetermined breaking points may remain, as described in more detail herein.

[0015] The material to be processed can preferably be a flat material, in particular a metallic flat material, e.g. a sheet of metal.

[0016] The term "in particular" is used in this description and the attached claims preferably to describe optional features.

[0017] The tools rotate around tool axes. Preferably, the tool axes run parallel to each other. It can be advantageous if the workpiece is deformed before or during punching and / or cutting, forming a three-dimensional structure and / or a convex surface zone and / or a concave surface zone on the workpiece. It can be advantageous if the concave surface zone is elongated and / or defines a channel for guiding a fluid and / or if the convex surface zone defines a support zone.

[0018] It can be particularly advantageous if the workpiece is a sheet metal suitable for a laminated core of a magnetic core.

[0019] It can be advantageous if the sheet metal is electrical steel.

[0020] It can be advantageous if the sheet metal is coated.

[0021] The sheet metal can have a bonding layer and / or an insulating layer.

[0022] The sheet metal can be coated with a bonding material and / or insulating material.

[0023] The bonding layer may contain the bonding material.

[0024] The insulation layer may contain the insulating material.

[0025] Advantageously, the bonding layer and / or the bonding material can make it possible to connect several shaped elements together over a flat surface.

[0026] Advantageously, the insulating layer and / or insulating material between joined molded elements can serve to electrically insulate them. For example, two molded elements can be electrically insulated from each other by the insulating layer and / or insulating material.

[0027] Advantageously, the bonding and / or insulating layer can be a combined bonding and insulating layer that allows several shaped elements to be joined together over a surface while electrically insulating them from one another. Advantageously, the thickness of the sheet can be 0.02 mm to 1 mm, particularly 0.1 mm to 0.6 mm, e.g., 0.15 mm to 0.45 mm. The thickness of the sheet does not include the thickness of any additional layers, such as bonding or insulating layers, that the sheet may have.

[0028] Advantageously, the thickness of the layer, e.g., bonding layer and / or insulating layer, in particular the bonding and insulating layer, can be 2 pm to 50 pm, preferably 3 pm to 30 pm, e.g., 4 pm to 20 pm.

[0029] It can be advantageous if the sheet metal has a bonding layer and / or insulating layer on only one of the two main surfaces.

[0030] It can be advantageous if the sheet metal has a bonding and insulating layer on only one of the two main surfaces.

[0031] It can be advantageous if the workpiece is not reshaped and / or if no three-dimensional structure is formed on the workpiece.

[0032] It can be particularly advantageous if the workpiece is not embossed and / or no three-dimensional structure is embossed into the workpiece.

[0033] It can be advantageous if the two tools rotate in opposite directions around the tool axes, which preferably run parallel to each other.

[0034] The statement that the form element is separated from the workpiece can, in particular, mean that the form element is separated out of the workpiece.

[0035] The statement that the mold element is incompletely or completely separated from the workpiece can, in particular, mean that the mold element is partially or completely removed from the workpiece. It can be advantageous if the mold element is incompletely separated from the workpiece.

[0036] This may refer in particular to punching and / or cutting.

[0037] It can be advantageous if the shaped element is incompletely separated from the workpiece during punching and / or cutting along the separation line.

[0038] In particular, the processing of the workpiece in the punching arrangement and / or cutting arrangement can be carried out by punching and / or cutting along the separation line defined by the punching arrangement and / or cutting arrangement in such a way that the shaped element is formed and incompletely separated from the workpiece.

[0039] Advantageously, the machining unit can comprise an inner shearing unit, wherein the inner shearing unit has an inner shearing edge, and the machining counter unit can comprise an outer shearing unit, wherein the outer shearing unit has an outer shearing edge, and the two shearing edges define the parting line.

[0040] Advantageously, the inner shear edge and the outer shear edge can be offset from each other by a shear gap.

[0041] It can be advantageous if the shear gap has a shear gap width that, in a closed state of the punching and / or cutting arrangement, is 2 to 20%, e.g. 5 to 10%, of the sheet thickness.

[0042] It can be advantageous if the inner shearing unit has or is a cutting punch element.

[0043] It can be advantageous if the outer shearing unit has or is a matrix element.

[0044] It can be advantageous if the processing unit has an internal counter-holding element which, when the punching and / or cutting arrangement is closed, is moved towards the inner shearing unit during the closing movement, and / or if the processing unit has an external counter-holding element which, when the punching and / or cutting arrangement is closed, is moved towards the outer shearing unit during the closing movement.

[0045] It can be advantageous if, during punching and / or cutting along the parting line, the resulting shaped element is held by the inner counter-holding element on the inner shearing unit and / or pressed against the inner shearing unit, and / or the workpiece is held by the outer counter-holding element on the outer shearing unit and / or pressed against the outer shearing unit in a shaped element environment adjacent to the resulting shaped element.

[0046] Advantageously, by holding the forming element in the workpiece, it can be retained in the workpiece and / or it can be made more difficult for the element to break out or fall out of the workpiece.

[0047] For example, the inner counter-holding element, the outer counter-holding element, or both counter-holding elements together can help ensure that a partially separated shape element remains reliably embedded in the workpiece after punching and / or cutting. This can make it possible to selectively remove the partially separated shape element in a subsequent separation step, thus allowing, for example, the separate removal and collection of several shape elements of varying sizes that can form between the two tools in the workpiece.

[0048] It can be advantageous if the inner retaining element is an elastic element. For example, the inner retaining element can be made entirely or partially of an elastic material, such as rubber.

[0049] It can be advantageous if the outer counter-support element is an elastic element.

[0050] The outer counter-holding element can, for example, consist entirely or partially of an elastic material, e.g., rubber.

[0051] It can be advantageous if, in the case of incomplete separation, a bridge and / or a predetermined breaking point remains, whereby the bridge and / or the predetermined breaking point connects the incompletely separated form element with the workpiece.

[0052] For example, the outer counter-holding element, the inner counter-holding element, or the counter-holding elements together can ensure that even a deliberately weak web and / or a deliberately weak predetermined breaking point can be created reliably and precisely during punching and / or cutting, without uncontrolled breakage. This, in turn, can contribute to requiring only minimal force during a subsequent separation operation in which the web and / or predetermined breaking point is selectively cut. Consequently, the resulting features produced by this process exhibit very few undesirable deformations that could otherwise occur during the separation operation.

[0053] It can be advantageous if the web and / or the predetermined breaking point is a first web and / or a first predetermined breaking point and, in the case of incomplete separation, a second web and / or a second predetermined breaking point remains, whereby the second web and / or the second predetermined breaking point also connects the incompletely separated form element with the workpiece.

[0054] It can be advantageous if, during incomplete separation, a third web and / or a third predetermined breaking point remains, whereby this third web and / or breaking point also connects the incompletely separated mold element to the workpiece. It can also be advantageous if, during incomplete separation, a fourth web and / or a fourth predetermined breaking point remains, whereby this fourth web and / or breaking point also connects the incompletely separated mold element to the workpiece.

[0055] A multiple of ribs and / or predetermined breaking points can be advantageous, as a mold element that is incompletely separated from the workpiece can remain attached to the workpiece at several different points via multiple ribs and / or predetermined breaking points.

[0056] It can be advantageous if the bridge and / or the predetermined breaking point, which remains after incomplete separation of the mold element from the workpiece, is created by weakening any material of the workpiece remaining in the area of ​​the bridge and / or the predetermined breaking point during the processing of the workpiece in the punching arrangement and / or cutting arrangement.

[0057] It can be advantageous if the material of the workpiece present in the area of ​​the bridge and / or the predetermined breaking point is weakened during the processing of the workpiece in the punching arrangement and / or cutting arrangement by forming a predetermined breaking zone in which the material of the workpiece is less thick than in an adjacent area of ​​the workpiece, and / or by forming at least two predetermined breaking sections spaced apart from each other along a predetermined breaking line.

[0058] The predetermined breaking point can preferably be created by tapering the material of the workpiece, e.g. by introducing, preferably pressing and / or embossing, a depression leading from a main surface of the workpiece into the workpiece.

[0059] The at least two predetermined breaking sections spaced apart along the predetermined breaking line can be formed in particular by piercing the material of the workpiece and / or by introducing a perforation into the material of the workpiece.

[0060] It can be particularly advantageous if the material of the workpiece present in the area of ​​the bridge and / or the predetermined breaking point is weakened during the processing of the workpiece in the punching arrangement and / or cutting arrangement by forming the predetermined breaking zone in which the material of the workpiece is less thick than in an adjacent area of ​​the workpiece, and by forming at least two predetermined breaking sections spaced apart from each other along a predetermined breaking line.

[0061] For example, the predetermined breaking point can be created by tapering the material of the workpiece and at the same time by piercing the material of the workpiece and / or introducing a perforation into the material of the workpiece.

[0062] It can be advantageous if, in a separation break zone

[0063] - at least one of the shearing units and / or at least one of the shearing edges is not continuous and / or

[0064] - at least one of the shear units and / or at least one of the shear edges has a shear edge interruption, wherein when the punching arrangement and / or cutting arrangement is completely closed, the bridge and / or the predetermined breaking point remains in the separation interruption zone.

[0065] Advantageously, a feature element edge can limit the area of ​​the feature element.

[0066] It can be particularly advantageous if, in several separation interruption zones spaced apart from each other along the separation line, at least one of the shear units and / or at least one of the shear edges is not continuous and / or

[0067] - each has at least one of the shear units and / or at least one of the shear edges a shear edge interruption, wherein when the punching arrangement and / or cutting arrangement is completely closed, one of several webs and / or predetermined breaking points spaced apart from each other along the edge of the form element remains in each of the separation interruption zones.

[0068] It can be advantageous if the dividing line defines a punched area and / or cut surface that determines the area of ​​the form element.

[0069] It is possible that the dividing line is interrupted in the area of ​​one or more webs and / or one or more predetermined breaking points. Nevertheless, the dividing line can define a punched surface and / or cut surface that determines the area of ​​the molded part. For the purpose of defining the punched surface and / or cut surface that determines the area of ​​the molded part, it can be assumed, in particular, that the dividing line is continuous even at any webs and / or predetermined breaking points that may be present. For example, two endpoints of the dividing line that lie at a web and / or a predetermined breaking point can be connected by a straight line, thereby interpolating the path of a dividing line in the area of ​​the web and / or the predetermined breaking point.

[0070] It can be advantageous if the workpiece is completely cut through along the separation line during punching and / or cutting, wherein the forming element is advantageously held in a punching and / or cutting recess created in the workpiece during punching and / or cutting by at least one counter-holding element, for example by the inner counter-holding element and / or the outer counter-holding element, or pressed back into a punching and / or cutting recess created during punching and / or cutting, and the incomplete separation of the forming element from the workpiece is thereby achieved.

[0071] In particular, the incomplete separation of the forming element from the workpiece can be achieved by means of a force-fit and / or press fit of the forming element in the punching recess and / or cutting recess.

[0072] It can be advantageous if the stamping surface and / or cutting surface has a projection zone and / or protrusion zone and / or nose zone, and the shaped element has a projection defined by the projection zone and / or a protrusion defined by the protrusion zone and / or a nose defined by the nose zone; and / or the stamping surface and / or cutting surface has at least one indentation zone and / or recess zone, and the shaped element has at least one indentation and / or recess defined by the at least one indentation zone and / or recess zone.

[0073] For example, the punching surface and / or cutting surface can have a square base shape, and the overhang zone and / or projection zone and / or nose zone can protrude from the square base shape.

[0074] For example, the design element may have a square base shape, and the overhang and / or projection and / or nose may extend beyond the square base shape.

[0075] For example, the indentation zone and / or recess zone can protrude into the square base shape.

[0076] For example, the indentation and / or recess can project into the rectangular base shape. The rectangular base shape can preferably be a right-angled shape.

[0077] It can be advantageous if the die-cutting surface and / or cutting surface has sides and side transition zones, e.g., corner zones.

[0078] - at least one of the pages lies between two page transition zones and / or connects two page transition zones and / or

[0079] - at least one of the side transition zones lies between two sides and / or connects two sides, wherein the dividing line at the side transition zones is curved in at least one section and at the sides is not curved or is less curved than in the at least one section in the side transition zones; wherein the form element has form element sides and form element side transition zones, e.g. form element corner zones, wherein

[0080] - at least one of the form element sides lies between form element side transition zones and / or connects two form element side transition zones, and / or

[0081] - at least one of the form element side transition zones lies between two form element sides and / or connects two form element sides, wherein the surface of the form element is bounded by a form element edge and the form element edge is curved in at least one edge section at the form element side transition zones and is not curved or is less curved in at least one edge section at the form element sides than in the at least one edge section in the form element side transition zones. A particularly strong curve of the dividing line and / or the form element edge can occur in each corner zone and / or form element corner zone, since a corner can be considered a particularly strong curve.

[0082] It can be advantageous if the stamped surface and / or cut surface has at least two overhang zones and / or at least two projection zones and / or at least two nose zones, and the shaped element has at least two overhangs defined by the overhang zones, at least two projections defined by the projection zone and / or at least two noses defined by the nose zone.

[0083] It can be advantageous if at least two of the side transition zones, e.g., at least two of the corner zones, are connected by a side, and in the two side transition zones connected by the side, at least one of the at least two overhang zones and / or the at least two projection zones and / or the at least two nose zones is present, wherein at least two of the form element side transition zones, e.g., at least two of the form element corner zones, are connected by a form element side, and in the two form element side transition zones connected by the form element side, at least one of the at least two overhangs and / or the at least two projections and / or at least one of the at least two noses is present.

[0084] It can be advantageous if at least one indentation zone and / or recess zone is present on at least one of the sides of the stamping surface and / or cutting surface, and if at least one indentation and / or recess is present on at least one of the form element sides of the form element.

[0085] It can be advantageous if the stamping surface and / or cutting surface has at least one indentation zone and / or recess zone, and the forming element has at least one indentation and / or recess defined by the at least one indentation zone and / or recess zone, and the stamping surface and / or cutting surface has at least one further indentation zone and / or recess zone, and the forming element has at least one further indentation and / or recess defined by the at least one further indentation zone and / or recess zone.

[0086] It can be advantageous if the die-cutting surface and / or cut surface has a central section and two end sections adjoining the central section, wherein the two end sections each comprise two of the side transition zones, wherein the die-cutting surface and / or cut surface tapers in at least one of the two end sections towards the central section in a stepped and / or continuous manner, or tapers in each of the two end sections towards the central section in a stepped and / or continuous manner, and / or tapers in at least one of the two end sections towards the central section in a stepped and / or continuous manner, or tapers in each of the two end sections towards the central section in a stepped and / or continuous manner, and the forming element has a forming element central section and two forming element end sections adjoining the forming element central section.wherein the two end sections of the form element each comprise two of the side transition zones of the form element, wherein the form element tapers in at least one of the two end sections towards the central section of the form element in a stepped and / or continuous manner, or tapers in each of the two end sections towards the central section of the form element in a stepped and / or continuous manner, and / or tapers in each of the two end sections towards the central section of the form element in a stepped and / or continuous manner, or tapers in each of the two end sections towards the central section of the form element in a stepped and / or continuous manner.

[0087] It can be advantageous if the protrusion, projection, nose, separation interruption zone, indentation and / or recess is held in a corresponding area of ​​the punching and / or cutting recess in the workpiece by at least one counter-holding element, for example by the inner counter-holding element and / or the outer counter-holding element, or is pressed back into a corresponding area of ​​the punching and / or cutting recess created during punching and / or cutting, and the incomplete separation of the forming element from the workpiece is thereby achieved or promoted, in particular by means of the force-fit and / or the press fit, at the protrusion, projection, nose, separation interruption zone, indentation and / or recess.

[0088] It can be advantageous if the separation break zone is a separation break zone formed at the overhang zone or at one of the overhang zones, at the projection zone or at one of the projection zones, at the nose zone or at one of the nose zones, at the side or at one of the sides, at the side transition zone or at one of the side transition zones, at the corner zone or at one of the corner zones, at the middle section and / or at one of the end sections.

[0089] It can be advantageous if the bridge and / or the predetermined breaking point connects the incompletely separated mold element to the workpiece at the overhang or at one of the overhangs, at the projection or at one of the projections, at the nose or at one of the noses, at the mold element side or at one of the mold element sides, at the mold element side transition zone or at one of the mold element side transition zones, at the mold element corner zone or at one of the mold element corner zones, at the mold element middle section and / or at one of the mold element end sections.

[0090] It can be advantageous if the process includes a punching and / or cutting step in which the processing of the workpiece is carried out in the punching and / or cutting arrangement by punching and / or cutting, wherein in the punching and / or cutting step the incomplete separation of the shape element from the workpiece takes place, and includes a separation step in which the shape element, incompletely separated from the workpiece, is completely separated from the workpiece.

[0091] For example, in the separation processing step, the mold element that is incompletely separated from the workpiece can be completely separated from the workpiece by separating the web, the webs, the predetermined breaking point and / or the predetermined breaking points.

[0092] It can be advantageous if the workpiece and the incompletely separated mold element are fed to a mold element separation arrangement for complete separation of the mold element from the workpiece, and it can be advantageous if the separation processing step is carried out using the mold element separation arrangement.

[0093] It can be advantageous if the processing unit is a large processing unit, the counter-processing unit is a large counter-processing unit, and the punching arrangement and / or cutting arrangement is a large punching arrangement and / or large cutting arrangement.

[0094] It can be advantageous if the dividing line is a long dividing line, the punching and / or cutting takes place along the long dividing line, and the form element is a large form element, with one of the two tools having a small machining unit and the other of the two tools having a small machining counter unit, and the small machining unit and the small machining counter unit together forming a small punching arrangement and / or small cutting arrangement.

[0095] It can be advantageous if the processing of the workpiece in the small punching arrangement and / or small cutting arrangement is carried out by punching and / or cutting along a short separation line defined by the small punching arrangement and / or small cutting arrangement in such a way that a small shaped element is incompletely or completely separated from the workpiece.

[0096] The terms "large processing unit," "small processing unit," "large processing counter-unit," "small processing counter-unit," "large punching arrangement," "small punching arrangement," "large cutting arrangement," and "small cutting arrangement" each indicate that one of the two processing units, processing counter-units, punching arrangements, and / or cutting arrangements mentioned is larger than the other. The same applies to the large form element in relation to the small form element. Consequently, the long dividing line mentioned in connection with the large units, large arrangements, and the large form element is typically longer than the short dividing line mentioned in connection with the small units, small arrangements, and the small form element.

[0097] In particular, the terms "large" and "small" as well as "long" and "short" can be relative terms that say nothing about how much larger the large units, large arrangements and the large formal element can each be in relation to the small units, small arrangements and the small formal element.

[0098] It can be advantageous if one of the tools has a first machining unit and a second counter-machining unit, and the other tool has a first counter-machining unit and a second machining unit.

[0099] For example, the first machining unit can be the large machining unit, the first counter-machining unit the large counter-machining unit, the second machining unit the small machining unit, and the second counter-machining unit the small counter-machining unit.

[0100] For example, the first processing unit can be the small processing unit, the first counter-processing unit the small counter-processing unit, the second processing unit the large processing unit, and the second counter-processing unit the large counter-processing unit.

[0101] It can be advantageous if the large and small forming elements are incompletely separated from the workpiece, and it can be advantageous if the incomplete separation of the large and small forming elements is carried out as described herein in connection with the forming element mentioned therein. This can relate in particular to punching and / or cutting.

[0102] It can be advantageous if the large and small forming elements are incompletely separated from the workpiece during punching and / or cutting along the separation lines.

[0103] In particular, the processing of the workpiece in the punching arrangement and / or cutting arrangement can be carried out by punching and / or cutting along the separation lines defined by the punching arrangements and / or cutting arrangements in such a way that the large form element and the small form element are formed and incompletely separated from the workpiece.

[0104] It can be advantageous if the large mold element is wider and / or longer than the small mold element, and it can be advantageous if the large mold element is wider than the small mold element, and it can be particularly advantageous if the large mold element is wider but not longer than the small mold element; and / or if an extent of the large mold element measurable in a direction of extension, e.g., width direction, e.g., width of the large mold element, is greater than an extent of the small mold element measurable in a direction of extension, e.g., width direction, e.g., width of the small mold element.

[0105] When reference is made here to the length and width of the feature, the length can refer to the larger and the width to the smaller of two orthogonally measurable dimensions of the feature. In particular, the two dimensions can be measured orthogonally to a thickness of the feature that is measurable along a thickness direction.

[0106] The width and length of the molded element are measured including any overhangs, projections, and / or lugs that may be present. Indentations and / or recesses, if present, are not taken into account when measuring lengths and / or widths.

[0107] Advantageously, the length of a shape element can be considered to be the length of the smallest rectangle beyond which the shape element does not extend.

[0108] Advantageously, the width of a shape element can be considered to be the width of the smallest rectangle beyond which the shape element does not extend.

[0109] It can be advantageous if, in the separation processing step in which the incompletely separated form element is completely separated from the workpiece, particularly when separating the web, webs, predetermined breaking point and / or predetermined breaking points, a form element edge zone, e.g. form element fracture edge zone, or several form element edge zones, e.g. several form element fracture edge zones, are created.

[0110] It is possible that the feature edge at the feature edge zone, e.g. at the feature break edge zone, or at the feature edge zones, e.g. at the feature break edge zones, differs from the feature edge in a feature punching edge zone and / or feature cutting edge zone resulting from the punching and / or cutting in the punching operation step and / or cutting operation step.

[0111] A difference can be advantageous, in particular, in stronger edge elevations and / or edge depressions, which result from the separation of the web, the webs, the predetermined breaking point and / or the predetermined breaking points.

[0112] The marginal elevations and / or depressions mentioned herein may be, in particular, marginal elevations and / or depressions formed orthogonally to a normal which intersects the two main surfaces of the form element and at the same time orthogonally to a course of the form element edge at the respective form element edge zone, e.g. form element fracture edge zones.Whether there are pronounced edge elevations and / or edge depressions resulting from the separation of the web, the webs, the predetermined breaking point and / or the predetermined breaking points can be determined, for example, by comparing the edge elevations and / or edge depressions in the mold element break edge zone with the edge elevations and / or edge depressions in the mold element punch edge zone and / or mold element cut edge zone, whereby an evaluation, measurement and / or quantification of the edge elevations and / or edge depressions is carried out orthogonally to the normal, in the mold element break edge zone additionally orthogonally to the course of the mold element edge at the mold element break edge zone and in the mold element punch edge zone and / or mold element cut edge zone additionally orthogonally to the course of the mold element edge at the mold element punch edge zone and / or mold element cut edge zone.

[0113] It can be advantageous if all element edge zones, e.g. element fracture edge zones, are formed on sections of the two element edges that cannot lie on top of each other, if the small element is arranged flat and parallel to the large element on the large element in such a way that the centers of gravity of both elements lie on top of each other.

[0114] This can be particularly helpful in preventing eddy current losses in electrical machines. It was found that, within the usual manufacturing tolerances, depending on the shape of webs and / or predetermined breaking points at the edge zones of molded elements, e.g., fracture edge zones, edge protrusions can occasionally occur that also extend slightly beyond one of the two main surfaces of the molded element.

[0243] For example, the feature can have: one feature edge zone, e.g., a feature break edge zone, or multiple feature edge zones, e.g., multiple feature break edge zones.

[0244] It may be advantageous if the form element is manufactured or available according to a process described herein, which includes the punching and / or cutting processing step and the separation processing step, using a processing unit and / or a processing counter-unit described herein.

[0245] It can be advantageous if the mold element edge zone, e.g., mold element fracture edge zone, or several of the mold element edge zones, e.g., several of the mold element fracture edge zones, are produced or available in the separation processing step by completely separating the mold element that was incompletely separated from the workpiece, in particular by separating the web, the webs, the predetermined breaking point and / or the predetermined breaking points.

[0246] It can be advantageous if the element edge at the element edge zone, e.g., at the element break edge zone, or at the element edge zones, e.g., at the element break edge zones, differs from the element edge in another zone of the element edge, where the other zone of the element edge can be, for example, a stamping edge zone and / or a cutting edge zone resulting from die-cutting and / or cutting.

[0248] The information provided in connection with the procedure for marginal elevations and / or marginal depressions may also apply in particular in connection with the form element.

[0249] For example, edge elevations and / or edge depressions in a feature fracture edge zone can be compared with any existing edge elevations and / or edge depressions in the other zone of the feature edge, whereby an evaluation, measurement and / or quantification of the edge elevations and / or edge depressions can be carried out orthogonally to the normal described in connection with the procedure, in the feature fracture edge zone additionally orthogonally to the course of the feature edge at the feature fracture edge zone and in the other zone additionally orthogonally to the course of the feature edge at the other zone.

[0254] It can be advantageous if the shaped element is not flat and / or has a three-dimensional structure; and / or has an embossing, where the embossing can be, for example, an embossed three-dimensional structure; and / or has a convex surface zone and / or a concave surface zone.

[0255] It can be advantageous if the concave surface zone is elongated and / or defines a channel for guiding a fluid.

[0256] It can be advantageous if the concave surface zone is elongated and / or defines a channel for guiding a fluid and / or the convex surface zone defines a support zone.

[0261] The object of the invention is achieved by the form element package according to the relevant independent claim. The form element package can, in particular, be a form element package for a magnetic core. Advantageously, this allows for the simple provision of an efficient electric drive, e.g., an efficient electric machine.

[0262] The component package comprises the following: components present in a layered composite, e.g. sheet metal components and / or components made from a sheet metal, wherein the sheet metal can be a sheet suitable for a laminated core of a magnetic core, e.g. electrical steel.

[0263] It can be advantageous if several or all of the shaped elements present in the layered composite are physically connected to each other via insulating layers, which electrically insulate the physically connected shaped elements completely or partially from each other.

[0264] All or part of the insulating layers, by which several of the shaped elements present in the layer assembly or all of the shaped elements present in the layer assembly are physically connected to each other, can, for example, be or be made from the connecting and / or insulating layer described herein in connection with the process.

[0265] It can be advantageous if at least one of the form elements of the form element package is a form element described herein.

[0266] It can be particularly advantageous if several of the form elements of the form element package are form elements described herein.

[0268] It can be advantageous if at least one of the two immediately adjacent features in the feature package is not flat and / or has a three-dimensional structure; and / or has an embossing, where the embossing can be, for example, the embossed three-dimensional structure; and / or has a convex surface zone and / or a concave surface zone.

[0269] It can be advantageous if the concave surface zone is elongated and / or defines the channel for guiding the fluid, with the channel running between the two immediately adjacent features in the mold assembly. This can, for example, enable the integration of temperature control, particularly cooling, into the mold assembly, where the fluid can be a temperature control fluid, particularly a cooling fluid. It can also be advantageous if the convex surface zone defines the support zone. If features in the mold assembly are immediately adjacent, this can particularly mean that no further feature, particularly no further sheet metal feature, is arranged between the immediately adjacent features. The immediate proximity of two features in the mold assembly does not preclude the existence of a layer between the two immediately adjacent features.An insulating layer and / or a bonding layer can be located between the two immediately adjacent molded elements to physically connect them. This layer can, for example, be a baked-on lacquer layer.

[0270] It can be advantageous if the two shape elements that are immediately adjacent in the shape element package are shape elements that have one shape element edge zone, e.g., a shape element break edge zone, or several shape element edge zones, e.g., several shape element break edge zones.

[0271] It can be advantageous if, in the feature package, no feature boundary zone, e.g., no feature break edge zone, of one of the two features is positioned in such a way that it overlaps or superimposes a feature boundary zone, e.g., feature break edge zone, of the other of the two features.

[0272] It can be advantageous if all feature edge zones, e.g., all feature break edge zones, of immediately adjacent features are offset from each other along the two feature edges of the two immediately adjacent features. In particular, it can be advantageous if all feature edge zones, e.g., all feature break edge zones, of the two features that are immediately adjacent in the feature package are offset from each other along the two feature edges of the two features that are immediately adjacent in the feature package.

[0273] This can advantageously reduce the risk of eddy current losses. If, as described, care is taken to ensure that the edge zones of molded parts, e.g., fracture edge zones, do not overlap or superimpose and / or are offset from each other within the molded part assembly of adjacent molded parts, unwanted electrical contacts that could otherwise occur between the edge zones, e.g., fracture edge zones, of immediately adjacent molded parts can be avoided with minimal effort.

[0276] It can be advantageous if indentations and / or recesses of several form elements, in particular several immediately adjacent form elements, of the form element package are completely or partially overlapped.

[0277] It can be particularly advantageous if the edges of features that run along the indentations and / or recesses of several features are wholly or partially overlapped within the feature set. This can be especially true for the edges of immediately adjacent features. It can also be advantageous if one of two features in the feature set is a large feature and the other is a small feature.

[0279] The small form element can in particular be a small form element described herein in connection with the process, the machining unit, the counter-machining unit, the tool, the tool arrangement and / or in connection with the machining system.

[0280] It can be advantageous if the large design element is wider and / or longer than the small design element.

[0281] It can be advantageous if the large shape element is wider than the small shape element.

[0282] It can be advantageous if the large design element is wider but not longer than the small design element.

[0283] It can be advantageous if the form element package tapers from a larger package end to a smaller package end in a stacking direction that is orthogonal to the main surface of the form elements and / or if at least one cross-section of the form element package is trapezoidal along a stacking direction that is orthogonal to the main surfaces of the form elements.

[0284] It can be advantageous if the cross-section of the element package is trapezoidal in at least one section along the stacking direction, which is oriented orthogonally to the main surfaces of the elements. This section of the cross-section can extend from an element of the element package located closer to the smaller end of the package to an element located closer to the larger end of the package.

[0291] It can be advantageous if the protrusions, projections and / or lugs of several features of the feature set overlap completely or partially and together make it difficult or impossible for the coil element to detach from the feature set, e.g., by slipping off, and it can be advantageous if the completely or partially overlapping protrusions, projections and / or lugs form a blocking zone and the blocking zone makes it difficult or impossible for the coil element to detach from the feature set, e.g., by slipping off.

[0292] It can be particularly advantageous if partially overlapping protrusions, projections and / or noses of several immediately successive shaping elements of the shaping element package along the stacking direction form a blocking zone and the blocking zone makes it difficult or prevents the coil element from detaching from the shaping element package, e.g. by slipping off.

[0293] The problem is solved according to the invention by the coil arrangement according to the relevant independent claim.

[0294] The coil arrangement can, in particular, be a coil arrangement for a rotor arrangement or for a stator arrangement of an electric machine. The electric machine can, for example, be an axial flux motor.

[0295] Advantageously, the coil arrangement allows for the simple and efficient electrical drive of an electric machine. The coil arrangement comprises several coil devices, as described herein, positioned around a coil arrangement axis, which can, for example, form a rotational axis of the electric machine.

[0296] It can be advantageous if, in at least one of the form element packages, the larger package end is turned away from the coil arrangement axis and the smaller package end is turned towards the coil arrangement axis, and / or in the form element packages of several coil devices, the larger package end is turned away from the coil arrangement axis and the smaller package end is turned towards the coil arrangement axis.

[0342] Identical or functionally equivalent elements are designated with the same reference symbols in all figures.

[0343] Fig. 1 schematically illustrates a method for processing a workpiece 100. The workpiece 100 is a flat material 102, in particular a metallic flat material 104, e.g. a sheet 106.

[0344] It can be advantageous if the sheet metal 106 is suitable for a laminated core of a magnetic core.

[0345] The machining of the workpiece 100 takes place between two tools 108. The two tools rotate around parallel tool axes 110.

[0346] One of the two tools 108 has a machining unit 112. The other of the two tools has a counter-machining unit 114.

[0347] The machining unit 112 and the counter-machining unit 114 together form a punching arrangement 116. The punching arrangement 116 can also be considered a cutting arrangement 118. This is particularly true if the lengths of the machining unit 112 and the counter-machining unit 114, measured in a circumferential direction of the tools 108, are very large compared to the circumferences of the tools 108.

[0348] To cover both punching and cutting, reference is made here to punching and / or cutting.

[0349] This is intended to cover, in particular, embodiments in which the lengths of the machining unit 112 and the counter-machining unit 114, measured in a circumferential direction of the tools 108, are very small compared to the respective circumference of the tools. In such cases, punching is generally performed.

[0350] This is intended to cover, in particular, embodiments in which the lengths of the machining unit 112 and the counter-machining unit 114, measured in a circumferential direction of the tools 108, are very large compared to the respective circumference of the tools. In such cases, cutting generally takes place.

[0351] The reference to punching and / or cutting is also intended to cover all intermediate embodiments in which not only punching and not only cutting takes place, but intermediate forms of both separation techniques occur.

[0352] The processing of the workpiece 100 in the punching arrangement 116 and / or cutting arrangement 118 is carried out by punching and / or cutting along a separation line defined by the punching arrangement 116 and / or cutting arrangement 118. The separation line is not visible in Fig. 1.

[0353] The punching and / or cutting along the separation line defined by the punching arrangement 116 and / or cutting arrangement 118 is carried out in such a way that a shaped element, which is also not shown in Fig. 1, is formed and is incompletely or completely separated from the workpiece 100.

[0354] Fig. 2 shows a schematic sectional view of a punching arrangement 116 and / or cutting arrangement 118, wherein the cutting plane and the two tool axes 110 lie in one plane. The machining unit 112 comprises an inner shearing unit 120, wherein the inner shearing unit 120 has an inner shearing edge 122.

[0355] The machining counter unit 114 comprises an outer shear unit 124, wherein the outer shear unit 124 has an outer shear edge 126.

[0356] The two shearing edges 122 and 126 define the dividing line 128.

[0357] In the example shown in Fig. 2, the inner shearing unit 120 is a cutting punch element 130 and the outer shearing unit 124 is a die element 132. The punching arrangement 116 and / or cutting arrangement 118 shown in Fig. 2 is a punching arrangement 116 and / or cutting arrangement 118 designed with a counter-holding element 134.

[0358] The processing counter unit 114 has an internal counter-holding element 136 which, when the punching arrangement 116 and / or cutting arrangement 118 is closed, is moved towards the internal shearing unit 120 during the closing movement.

[0359] Since one of the two tools 108 shown in Fig. 1 has the machining unit 112 and the other of the two tools 108 shown in Fig. 1 has the counter-machining unit 114, and since both the machining unit 112 and the counter-machining unit 114 rotate, not only is the inner counter-holding element 136 moved towards the inner shearing unit 120 during the closing movement, but the inner shearing unit 120 is also moved towards the inner counter-holding element 136 during the closing movement. This is a necessary consequence of the two opposing rotational movements performed by the machining unit 112 and the counter-machining unit 114.

[0360] In the punching arrangement 116 and / or cutting arrangement 118, which is shown schematically in Fig. 2, the counter-holding element 134 is guided in a guide 138. It is supported by elastic elements 140. The elastic elements 140 shown in Fig. 2 can, for example, be compression spring elements 142.

[0361] In the process for machining the workpiece 100, the molded element can be incompletely separated from the workpiece 100. This is illustrated, for example, in Fig. 3, which shows a molded element 144 that has been incompletely separated from the workpiece 100. In the case of incomplete separation, webs 146 and / or predetermined breaking points 148 can remain, with the webs 146 and / or the predetermined breaking points 148 connecting the molded element 144, which has been incompletely separated from the workpiece 100, to the workpiece 100.

[0362] Advantageously, during punching and / or cutting along the parting line 128, the resulting shaped element 144 can be held on the inner shearing unit 120 and / or pressed against the inner shearing unit 120 by the inner counter-holding element 136, which is shown in Fig. 2.

[0363] It can be advantageous if, by counter-holding and / or pressing against the inner shearing unit, the forming shape element 144 is held in the workpiece 100 and / or if breaking out or falling out of the workpiece element 144 is made more difficult.

[0364] For example, the inner counter-holding element 136 can make it more difficult and / or prevent a breakage of a web 146 and / or a predetermined breaking point 148.

[0365] Fig. 4 shows a schematic perspective sectional view of a section of an outer shearing unit 124. This could be a matrix element 132.

[0366] Fig. 4 illustrates a separation interruption zone 150 in which the outer shearing unit 124 and its outer shearing edge 126 are not continuous. In the separation interruption zone 150, the outer shearing edge 126 has a shearing edge interruption 152.

[0367] When the punching arrangement 116 and / or cutting arrangement 118 is completely closed, a web 146 and / or a predetermined breaking point 148 remains in the separation interruption zone 150.

[0368] Figure 5 shows perspective views of an inner shearing unit 120 and an outer shearing unit 124. It is clearly evident from Figure 5 that the inner shearing unit is a cutting punch element and its inner shearing edge 122 is a punch shearing edge 154. It is also clearly evident from Figure 5 that the outer shearing unit 124 is a die element 132 and its outer shearing edge 126 is a die shearing edge 156. In a specific section of the parting line 128 defined by the punching arrangement 116 and / or cutting arrangement 118, both shearing edges 122 and 126 each have a shearing edge interruption 152.

[0369] The shear edge interruption of the inner shear edge 122 is a punch shear edge interruption 158. The shear edge interruption 152 of the outer shear edge 126 is a die shear edge interruption 160. The two shear edge interruptions 152, 158 and 152, 160 together form a parting break zone 150.

[0370] When the punching arrangement 116 and / or cutting arrangement 118 is completely closed, a web 146 and / or a predetermined breaking point 148 remains in the separation interruption zone 150 between the resulting shaped element 144 and the surrounding workpiece 100.

[0371] A fully closed state of the punching arrangement 116 and / or the cutting arrangement 118 is indicated in Fig. 6.

[0372] Figures 7 to 10 show sections through Figures 5 and 6.

[0373] Figures 7 and 8 show the open state of the punching arrangement 116 and / or cutting arrangement 118, whereas Figures 9 and 10 show the closed state of the punching arrangement 116 and / or cutting arrangement 118.

[0374] The sections shown in Figures 7 to 10 can be seen in Figures 5 and 6. There, the sections corresponding to Figures 7 to 10 are indicated by the corresponding Roman numerals.

[0375] In contrast to Figs. 5 and 6, in Figs. 7 to 10 the workpiece 100 is also shown, and in Figs. 9 and 10 the resulting form element 144 is also indicated.

[0376] Furthermore, Figures 7 to 10 also show counter-holding elements 134. One of the two counter-holding elements 134 shown is an inner counter-holding element 136. The other of the two counter-holding elements 134 shown is an outer counter-holding element 162.

[0377] Figures 7 to 10 show punching arrangements 116 and / or cutting arrangements 118 formed by processing units 112 and processing counter units 114, wherein the processing unit 112 has an outer counter-holding element 162 which, when the punching arrangement 116 and / or cutting arrangement 118 is closed (Figures 9 and 10), is moved towards the outer shearing unit 124 during the closing movement.

[0378] In particular, Figures 9 and 10 show how the workpiece 100 is held and / or pressed against the outer shearing unit 124 by the outer counter-holding element 162 in a forming element environment 164 adjacent to the forming element 144 of the workpiece 100.

[0379] The cut shown in Fig. 10 is made through the separation interruption zone 150. It can be clearly seen that the workpiece 100 is not cut through in the separation interruption zone 150, whereas it is cut through along the separation line elsewhere (Fig. 9).

[0380] It is possible to create a ridge 146 and / or a predetermined breaking point 148, which remains after the incomplete separation of the forming element 144 from the workpiece 100, by weakening material 166 of the workpiece 100 present in the area of ​​the ridge 146 and / or the predetermined breaking point 148 during processing of the workpiece 100 in the punching arrangement 116 and / or cutting arrangement 118. Figures 11 to 14 illustrate various possibilities for such weakening of the material 166 of the workpiece 100 present in the area of ​​the ridge 146 and / or the predetermined breaking point 148.

[0381] For example, as illustrated in Figs. 11 and 12, at least two mutually spaced predetermined breaking sections 170 can be formed along a predetermined breaking line 168, in particular by piercing the material 166 of the workpiece and / or by introducing a perforation 172 into the material 166 of the workpiece 100.

[0382] For example, several mutually spaced predetermined breaking sections 170 can be created along a predetermined breaking line 168 by piercing the material 166 of the workpiece and / or by introducing a perforation 172 into the material 166 of the workpiece with piercing elements 174, which are shown by way of example in Fig. 11. Fig. 11 shows a shear edge interruption 152, which is essentially similar to the shear edge interruptions 152 shown in Figs. 4 to 6, wherein piercing elements 174 in the form of piercing teeth 176 are formed within the shear edge interruption 152. The piercing elements or piercing teeth together form a perforation arrangement 178. When using a shear edge interruption 152 shown in Fig. 11 instead of the shear edge interruptions 152 shown in Figs. 4 to 10, perforations 172 can be produced as shown in Fig. 12.

[0383] In this process, a predetermined breaking zone 180 can be formed in which the material 166 of the workpiece 100 is less thick than in an adjacent area 182 of the workpiece 100.

[0384] Advantageously, the predetermined breaking zone can be created by tapering the material 166 of the workpiece 100, e.g. by introducing, preferably pressing and / or embossing, a depression 186 leading from a main surface 184 of the workpiece 100 into the workpiece 100.

[0385] Fig. 15 shows two further tools 108. The tools 108 can rotate about parallel tool axes 110, which are not shown in the section shown in Fig. 15. Machining of a workpiece 100, which is also not shown in Fig. 15, can take place between the two tools 108.

[0386] One of the two tools 108 shown in Fig. 15 has a machining unit 112. The other of the two tools 108 shown in Fig. 15 has a counter-machining unit 114. The machining unit 112 and the counter-machining unit 114 together form a punching arrangement 116 and / or cutting arrangement 118.

[0387] The processing of a workpiece in the punching arrangement 116 and / or cutting arrangement 118 is carried out by punching and / or cutting along a separation line defined by the punching arrangement 116 and / or cutting arrangement 118 in such a way that a shaped element is formed and is incompletely or completely separated from the workpiece.

[0388] The machining unit 112 comprises an inner shearing unit 120. The inner shearing unit 120 is a cutting punch element 130. The machining counter unit 114 comprises an outer shearing unit 124. The outer shearing unit 124 is a die element 132. The two shearing edges of the two shearing units 120 and 124 define the parting line in a manner similar to that illustrated by way of example in Figures 4 to 10.

[0389] The processing counter unit 114 has an internal counter-holding element 136 which, when the punching arrangement 116 and / or cutting arrangement 118 is closed, is moved towards the internal shearing unit 120 during the closing movement.

[0390] The processing unit 112 has an outer counter-holding element 162 which, when the punching arrangement 116 and / or cutting arrangement 118 is closed, is moved towards the outer shearing unit 124 during the closing movement.

[0391] Advantageously, the inner counter-holding element 136 can be a die-side punch counter-holding element 188.

[0392] Advantageously, the outer counter-holding element 162 can be a die-side counter-holding element 190.

[0393] It can be advantageous if the inner counter-holding element 136 is an elastic element 191, e.g. a rubber element 192.

[0394] It can be advantageous if the outer counter-holding element 162 is an elastic element 191, e.g. a rubber element 192.

[0395] To make the belonging of the various units and elements to the processing unit 112 or to the processing counter unit 114 more clearly visible, the two tools 108 and the two units, i.e. the processing unit 112 and the processing counter unit 114, are shown spaced apart from each other.

[0396] Fig. 16 shows the processing unit 112 and the counter-processing unit 114 of the punching arrangement 116 and / or cutting arrangement 118 shown in Fig. 15. In Fig. 16, the two sides of the processing unit 112 and the counter-processing unit 114, which are facing each other in Fig. 15, are facing the viewer.

[0397] The processing unit 112 shown in Fig. 16 is a processing unit for processing a workpiece 100, wherein a form element 144 can be formed from the workpiece 100 with the processing unit 112 and can be incompletely separated from the workpiece.

[0398] The processing can be carried out, for example, according to a method indicated in Fig. 1, whereby the workpiece can be, for example, a workpiece shown there.

[0399] The machining unit 112 shown in Fig. 16 has an inner shearing unit 120. The inner shearing unit 120 is a cutting punch element 130. The inner shearing unit 120 has an inner shearing edge 122.

[0400] The machining unit 112 shown in Fig. 16 also has an outer counter-holding element 162. The outer counter-holding element 162 is a die-side counter-holding element 190.

[0401] The processing unit 112 shown in Fig. 16 also has a separation interruption zone not shown in the figure for generating a web and / or a predetermined breaking point, wherein the web and / or the predetermined breaking point connects a form element, which can be produced from the workpiece with the processing unit 112, to the workpiece.

[0402] The separation interruption zone can, for example, be one of the separation interruption zones 150 described in connection with Figures 4 to 14. It can be advantageous if the inner shear edge 122 is not continuous in the separation interruption zone 150, for example as shown in Figures 11 and 13.

[0403] Advantageously, the processing unit 112 shown in Fig. 16 can have a material weakening unit 194 in the separation interruption zone 150. The material weakening unit 194 can enable a weakening of the material 166 of the workpiece 100 at the web 146 and / or at the predetermined breaking point 148.

[0404] An alternative material weakening unit 194 is shown in Fig. 13.

[0405] With the material weakening unit 194 shown in Fig. 13, a predetermined breaking point 180 can be formed in which the material 166 of the workpiece 100 is thinner than in an adjacent area 182 of the workpiece 100. For example, the predetermined breaking point 180 can be created by tapering the material 166 of the workpiece 100, e.g., by introducing, preferably by pressing and / or embossing, the material weakening unit 194 from a main surface 184 of the workpiece 100 into the workpiece 100. For this purpose, the inner shearing unit 120 shown in Fig. 16 can be configured in a separation interruption zone 150, for example, as shown in Fig. 13 for the inner shearing unit with material weakening unit 194 shown there.

[0406] Advantageously, a predetermined breaking line 168 can be defined with the material weakening unit 194, which the processing unit 112 from Fig. 16 can have, which has several mutually spaced predetermined breaking sections 170, wherein the material weakening unit 194 can advantageously have a piercing element 174, e.g. a piercing tooth 176, which enables piercing of the material 166 of the workpiece 100 and / or the introduction of a perforation 172 into the material 166 of the workpiece 100.

[0407] Advantageously, a material weakening unit 194 of the processing unit 112 shown in Fig. 16 can have several spaced-apart piercing elements 174, and the piercing elements 174 can form a perforation arrangement 178, whereby the perforation 172 can be introduced into the material 166 of the workpiece 100. This is clearly shown in Figs. 11 and 12. Fig. 11 additionally shows piercing elements 174, e.g., piercing teeth 176, which can act on a workpiece 100 in the opposite direction, e.g., from above. The interaction of the piercing elements 174 of different perforation arrangements 178 acting from above and from below can result in the perforation 172 shown in Fig. 12.

[0408] Alternatively or additionally, a material weakening unit 194, as shown in Fig. 13, can have a wedge-shaped material weakening element 196. It can be advantageous if the predetermined breaking zone 180, shown in Fig. 14, can be formed (in / with?) the wedge-shaped material weakening element 196 and / or if the material of the workpiece 100 can be tapered from a main surface 184 of the workpiece 100 into the workpiece 100 by pressing and / or embossing the wedge-shaped material weakening element 196. In the processing unit 112 shown in Fig. 16, a punched surface 198 and / or cut surface 200, which determines the area of ​​the forming element 144, is defined by the inner shear edge 122. The die-cut surface 198 and / or cut surface 200 has a projection zone 202. The projection zone 202 also represents a protrusion zone 204, which can also be considered a nose zone 206.

[0409] The die-cutting area 198 and / or cutting area 200 has sides 208 and side transition zones 210. The side transition zones 210 can be considered corner zones 212 of the die-cutting area 198 and / or the cutting area 200.

[0410] Pages 208 are located between two page transition zones 210. Pages 208 connect two page transition zones 210.

[0411] Each page transition zone 210 lies between two pages 208 and connects the two pages 208.

[0412] Fig. 16 clearly shows that the inner shear edge 122 is curved at least in one section at the side transition zones 210 and is not curved at least in one section at the sides 208.

[0413] Fig. 16 shows that the die-cut surface 198 and / or cut surface 200 has four overhang zones 202. Two of the side transition zones 210 are connected by one of the four sides 208. In each of the two side transition zones connected by the side, there are two overhang zones.

[0414] The four overhang zones are located in the four lateral transition zones.

[0415] The explanations given for the machining unit 112 in Fig. 16 also apply accordingly to the machining counter-unit 114, which is also shown in Fig. 16. The main differences between the machining counter-unit 114 shown below in Fig. 16 and the machining unit 112 shown above in Fig. 16 are that the machining counter-unit 114 has an outer shearing unit 124 instead of the inner shearing unit 120 and an inner counter-holding element 136 instead of the outer counter-holding element 162. The outer shearing unit 124 is a die element 132. The inner counter-holding element 136 is a die-side punch counter-holding element 188. Advantageously, the die-side punch counter-holding element 188 can also be an elastic element 191, e.g., a rubber element 192. Fig.Figure 16 illustrates, using the processing unit 114, that the punching surface 198 and / or the cutting surface 200 has a central section 214 and two end sections 216 adjoining the central section 214, wherein the two end sections each comprise two of the side transition zones, wherein the punching surface 198 and / or cutting surface 200 taper continuously towards the central section 214 in the two end sections 216.

[0416] The section shown between the broken lines added below in Fig. 16 can be considered, for example, as a middle section 214. The two sections adjoining the two broken lines can be considered as end sections 216.

[0417] The inner shearing edge 122 and the outer shearing edge 126 are only minimally offset from each other in the punching arrangement 116 and / or cutting arrangement 118 shown in Fig. 15. The parting line runs along the inner shearing edge and the outer shearing edge.

[0418] By having the punched surface 198 and / or cut surface 200 have the overhang zone 202 and / or the projection zone 204 and / or the nose zone 206, a shaped element 144 is formed which has an overhang 218 defined by the overhang zone 202 and / or a projection 220 defined by the projection zone 204 and / or a nose defined by the nose zone 206. Fig. 18 shows three shaped elements 144 arranged one above the other in perspective, each having four overhangs 218, projections 220 and noses 222. The smaller shaped elements 144 shown below in Fig. 18 can be produced with correspondingly smaller cooperating machining units 112 and machining counter-units 114. Fig. 17 shows an example of a smaller machining unit and an associated smaller machining counter-unit.

[0419] If the die-cutting surface 198 and / or cutting surface 200, unlike the examples in Figures 16 and 17, additionally has indentation zones and / or recess zones, then, for example, one of the form elements shown in Figure 18 can be produced, which additionally has indentations 224 and / or recesses 226 defined by the indentation zone and / or recess zone. Advantageously, if the die-cutting surface 198 and / or cutting surface 200 is designed with respect to sides 208, side transition zones 210, and corner zones 212 in the same or a similar way as shown in Figures 16 and 17, form elements 144 can be obtained that have form element sides 228, form element side transition zones 230, e.g., form element corner zones 232.

[0420] Advantageously, as shown in Fig. 18, at least one of the form element sides 228 can lie between two form element side transition zones 230 and / or connect two form element side transition zones 230.

[0421] Advantageously, as also shown in Fig. 18, at least one of the form element side transition zones 230 can lie between two form element sides 228 and / or connect two form element sides 228.

[0422] Advantageously, the surface of the molded element 144 can be bounded by a molded element edge 234, and the molded element edge 234 can be curved at least in one edge section at the molded element side transition zones 230, and at least in one edge section on the molded element sides can be straight or less curved than in the at least one edge section in the molded element side transition zones 230. In the examples shown in Fig. 18, the molded element edge 234 is straight at least in one edge section on the molded element sides 228.

[0423] The form elements 144 shown in Fig. 18 each have four projections 218, which can also be understood as protrusions 220 and / or noses 222.

[0424] The indentations 224 and / or recesses 226 shown in Fig. 18 are each located on one of the form element sides 228 of the form element 144.

[0425] If the conditions described in connection with Fig. 16 regarding the central section 214 and the end sections 216 apply to the stamping surface 198 and / or the cut surface 200, a forming element 144 can be obtained which, as indicated in Fig. 18, has a forming element central section 236 and two forming element end sections 238 adjoining the forming element central section 236, wherein the two forming element end sections 238 each comprise two of the forming element side transition zones 230, and wherein the forming element 144 tapers continuously towards the forming element central section 236 in each of the two forming element end sections 238.

[0426] The web 146 and / or the predetermined breaking point 148 or the webs 146 and / or the predetermined breaking points 148 can connect a mold element 144 that is incompletely separated from the workpiece 100, for example at the projection 218 or projections 218, at the protrusion 220 or projections 220, at the nose 222 or noses 222, at the mold element side 228 or mold element sides 228, at the mold element side transition zone 230 or mold element side transition zones 230, at the mold element corner zone 232 or mold element corner zones 232, at the mold element middle section 236 and / or at one of the mold element end sections 238 or at both mold element end sections 238, to the workpiece 100.

[0427] Possible positions at which webs 146 and / or predetermined breaking points 148 can connect a form element 144, which is incompletely separated from the workpiece 100, to the workpiece 100 are indicated by added arrows on the form elements shown in Fig. 18.

[0428] Naturally, separation interruption zones 150 can be present at corresponding locations of a punching arrangement 116 and / or a cutting arrangement 118.

[0429] Figure 19 shows that the method can comprise a punching and / or cutting step and a separation step. In the punching and / or cutting step, the workpiece 100 can be processed in the punching arrangement 116 and / or cutting arrangement 118 by punching and / or cutting, wherein in the punching and / or cutting step, the shaped element can be incompletely separated from the workpiece 100. In the separation step, the shaped element 144, which is incompletely separated from the workpiece 100, can be completely separated from the workpiece 100. This can be achieved, in particular, by separating the web 146, the webs 146, the predetermined breaking point 148, and / or the predetermined breaking points 148. Figure 19 illustrates this process.Figure 19 also shows that the workpiece 100 and the mold element 144, which is incompletely separated from the workpiece 100, can be fed to a mold element separation arrangement 240 for the complete separation of the mold element 144 from the workpiece 100.

[0430] Advantageously, the separation processing step can be carried out using the form element separation arrangement 240.

[0431] For example, the workpiece 100 can be conveyed in a conveying direction 242, after passing through the punching processing step and / or the cutting processing step, into the form element separation arrangement 240.

[0432] The machining units 112 and the machining counter-units 114 shown in Fig. 19 are only schematically indicated on the two tools 108. Only individual machining units and machining counter-units are provided with corresponding reference numerals. A machining unit is a large machining unit 244. A machining counter-unit 114 is a large machining counter-unit 246. The punching arrangement 116 and / or cutting arrangement 118, which is defined by the large machining unit 244 and the large machining counter-unit 246, represents a large punching arrangement 248 and / or a large cutting arrangement 250.

[0433] A processing unit 112 is a small processing unit 252. A processing counter unit 114 is a small processing counter unit 254. Together, the small processing unit 252 and the small processing counter unit 254 constitute a small punching arrangement 256 and / or a small cutting arrangement 258.

[0434] Fig. 16 shows an example of a larger machining unit and a larger machining counter-unit. Fig. 17 shows an example of a smaller machining unit and a smaller machining counter-unit. The large machining unit 244 and large machining counter-unit 246 shown in Fig. 19 can, for example, be designed in the same way as shown in Fig. 16. The small machining unit 252 and small machining counter-unit 254 shown in Fig. 19 can, for example, be designed as shown in Fig. 17. The machining of the workpiece 100 in the small punching arrangement 256 and / or small cutting arrangement 258 can be carried out by punching and / or cutting along a short separation line defined by the small punching arrangement 256 and / or small cutting arrangement 258, such that a small shaped element 260 is incompletely separated from the workpiece.

[0435] The processing of the workpiece 100 in the large punching arrangement 248 and / or large cutting arrangement 250 by punching and / or cutting along a long separation line defined by the large punching arrangement 248 and / or large cutting arrangement 250 can be carried out in such a way that a large form element 262 is incompletely separated from the workpiece 100.

[0436] Fig. 18 shows at the bottom an example of a small form element 260 and at the top an example of a large form element 262.

[0437] Figure 19 clearly shows that in the illustrated process, large form elements 262 and small form elements 260 are incompletely separated from the workpiece 100. This applies to the punching and / or cutting operations performed between the two tools 108. Only in the separation operation, which is carried out by means of the form element separation arrangement 240, are the large form elements 262 and the small form elements 260 completely separated from the workpiece 100.

[0438] For example, a large mold element 262 obtainable by the method shown in Fig. 19 can be wider and / or longer than the small mold element 260 obtainable by this method.

[0439] In the separation processing step, in which the partially separated molded element 144 is completely separated from the workpiece 100, a molded element edge zone 264 or several molded element edge zones 264 can be formed, particularly when separating the web 146, the webs 146, the predetermined breaking point 148 and / or the predetermined breaking points 148. Fig. 20 shows a molded element 144 that has two molded element edge zones 264. The form element edge zones are form element break edge zones 266. The form element edge 234 differs at the form element edge zone 264, i.e. at the form element break edge zone 266, from the form element edge 234 in a form element punching edge zone 268 and / or form element cutting edge zone 270 resulting from the punching and / or cutting in the punching operation step and / or cutting operation step.One difference lies in the more pronounced edge ridges 272 and edge depressions 274, which result from the separation of a predetermined breaking point 148. The edge ridges 272 and edge depressions 274 shown in Fig. 20 can be obtained in this or a similar manner, for example, by separating a perforation 172. Fig. 12 shows such a perforation. However, the perforation shown in Fig. 12 has a number of predetermined breaking sections 170 that does not correspond to the number of edge ridges in Fig. 20 resulting from such predetermined breaking sections 170.

[0440] Advantageously, as illustrated in Fig. 19, a large mold element 262 and a small mold element 260, which are incompletely separated from the workpiece 100, can be completely separated from the workpiece 100 in different mold element separation zones 276. Alternatively or additionally, a large mold element 262 and a small mold element 260, which are incompletely separated from the workpiece 100, can be removed and / or collected from the workpiece in different mold element discharge zones 278 and / or mold element collection zones 280.

[0441] It can be advantageous if the mold element separation zones 276 are spatially separated from each other. It can be advantageous if the mold element discharge zones 278 are spatially separated from each other. It can be advantageous if the mold element collection zones 280 are spatially separated from each other.

[0442] Fig. 21 shows a tool 108 for machining a workpiece 100. The tool 108 is suitable, for example, for carrying out a method described with reference to the preceding figures.

[0443] The tool 108, shown in Fig. 21, has a plurality of machining units 112. Only some of the machining units are provided with a reference numeral. From the perspective view of the tool 108, it is clearly evident that the tool 108 is annular and hollow cylindrical.

[0444] The tool 108 can be rotated about an indicated tool axis 110.

[0445] The machining units 112 are arranged radially outside the tool 108. It is clearly evident that the tool 108, shown in Fig. 21, has machining units 112 of different sizes. For example, one of the larger machining units 112 designated with reference numerals can be considered a large machining unit 244, and one of the machining units designated with reference numerals 112 can be considered a small machining unit 252.

[0446] The processing units 112, 244, 252 are only schematically indicated in Fig. 21.

[0447] It is not apparent from Fig. 21 that these processing units 112, 244, 252, for example, may have one or more features of the processing units mentioned in connection with the figures already described.

[0448] Fig. 21 shows that the small machining unit 252 is arranged radially outside the tool 108, offset from the large machining unit 244.

[0449] Figures 1 and 19 each show tool arrangements 282 for punching and / or cutting a workpiece 100. The tool arrangements 282 shown there each have two tools 108 which can be rotated about parallel tool axes 110 so that the workpiece 100 can be machined between the tools 108.

[0450] Figure 19 clearly shows that each of the two tools 108 can have the machining units 112, and each of the other two tools 108 can have the counter-machining units 114. Each machining unit 112 forms a punching arrangement 116 and / or cutting arrangement 118 with each counter-machining unit. To enable the desired interaction of each machining unit with a counter-machining unit, the two tools 108 can be rotated synchronously in opposite directions about the two tool axes 110.

[0451] Fig. 19 also shows a machining system 284 for punching and / or cutting a workpiece 100.

[0452] The machining system 284 comprises the tool arrangement 282 and the feature separation arrangement 240. Using the tool arrangement 282, a feature 144, in particular a large feature 262 and a small feature 260, can be formed from the workpiece 100, incompletely separated from the workpiece.

[0453] By means of the mold element separation arrangement, the mold element 144, which is incompletely separated from the workpiece, can be completely separated from the workpiece. In particular, by means of the mold element separation arrangement 240, the two or more mold elements 144, 260, 262, which are incompletely separated from the workpiece, can be completely separated from the workpiece.

[0454] Fig. 22 shows a form element package 286. It is a form element package 286 for the magnetic core 288 which is also shown.

[0455] The form element package 286 comprises form elements 144 arranged in a layered composite 290. All form elements 144 are sheet metal form elements 292. They are form elements 144 made from a sheet 106. The sheet 106 is a sheet suitable for a sheet metal package 294 of a magnetic core 288, for example, an electrical steel sheet 296.

[0456] All the shaped elements 144 present in the layered assembly 290 are physically connected to one another via insulating layers (not shown). The insulating layers electrically isolate the physically connected shaped elements 144 from each other, either completely or partially.

[0457] The form elements of the form element package 286 shown in Fig. 22 have form element edge zones 264. The form element edge zones 264 are only indicated in Fig. 22. The form element edge zones 264 are form element fracture edge zones 266.

[0458] None of the form elements shown in Fig. 22 has a form element edge zone 264 or a form element fracture edge zone 266 that overlaps or is superimposed on a form element edge zone 264 or a form element fracture edge zone 266 of an immediately adjacent form element 144.

[0459] For example, as shown in Fig. 22, all form element edge zones 264, e.g. all form element fracture edge zones 266, of immediately adjacent form elements 144 can be offset from each other along the form element edge 234.

[0460] Figure 22 clearly shows that the projections 218, protrusions 220, and lugs 222 of the form elements 144 of the form element assembly 286 partially overlap and together make it difficult or impossible for a coil element 298, which can be attached to the form element assembly 286 and is only schematically indicated in Figure 22, to detach from the form element assembly 286, e.g., to slip off. The partially overlapping projections 218, protrusions 220, and lugs 222 each form blocking zones 300 over which the coil element 298 cannot be moved without damage.

[0461] Areas of the form element package 286 covered by the coil element 298 are partly shown with dashed lines.

[0462] Areas of the coil element 298 covered by the form element package 286 are also partly shown as dashed lines.

[0463] Indentations 224 and recesses 226 of several form elements 144 of the form element package 286 shown in Fig. 22 are superimposed.

[0464] Figure 22 clearly shows that the form elements 144 depicted therein are of different sizes. If the form elements 144 of the form element package 286 are considered in pairs, one of the two form elements 144 can always be considered a large form element 262 and the other of the two form elements 144 a small form element 260. The form element package 286 shown in Figure 22 tapers in a stacking direction 302, which is oriented orthogonally to the main surfaces of the form elements, from a larger package end 304 to a smaller package end 306.

[0465] A cross-section of the form element package 286 shown in Fig. 22 along the stacking direction 302 is trapezoidal.

[0466] Figure 22 at the bottom right shows a schematic representation of an electric machine 308. The electric machine 308 is an axial flux motor 310.

[0467] The electric machine 308 can be used to fully or partially power a vehicle (not shown in Fig. 22). The vehicle can be, for example, a land vehicle, e.g., a road vehicle, or an aircraft, e.g., an airplane.

[0468] Advantageously, the electric machine 308 can have a stator arrangement 312 and / or a rotor arrangement 314.

[0469] One of these two arrangements, stator arrangement 312 or rotor arrangement 314, can, for example, be designed as shown in a simplified schematic representation in Fig. 22.

[0470] Fig. 22 shows a roughly simplified perspective view of a section of a coil arrangement 316.

[0471] For example, a stator arrangement 312 of the electric machine 308 can have the coil arrangement 316.

[0472] The coil assembly 316 comprises several coil devices 318. The coil devices 318 are positioned around a coil assembly axis 320. The coil assembly axis 320 is a rotation axis 322 of the electrical machine 308. In the element packages 286 of the coil devices 318, the larger package end 304 faces away from the coil assembly axis 320, and the smaller package end 306 faces the coil assembly axis 320. Fig. 23 shows a simplified schematic cross-section through one of the coil devices 318. The distances between the elements 144 of the element package 286 are exaggerated.

[0473] Fig. 23 also shows the coil element 298 attached to the form element package 286. A magnetic field can be generated with the coil element 298.

[0474] Figure 23 clearly shows that the coil element 298 has an annular conducting zone 321. The annular conducting zone 321 extends around the form element package 286. An electric current can be conducted through the conducting zone 321. The magnetic field can be generated by the electric current. The coil element 298 defines a center line 323 extending through the annular conducting zone 321. In Figure 23, the center line 323 points towards the viewer.

[0475] A smallest distance 324 of the central line 323 to the guide zone 321 is larger than the smallest distances of all other lines that extend through the coil element 298.

[0476] The main surfaces 184 of the form elements 144 of the form element package 286 are aligned parallel to the central line 323.

[0477] In all coil devices 318 shown in Fig. 22, the center lines 323, which are not shown in Fig. 22, are each aligned parallel to the coil arrangement axis 320.

[0478] The section shown in Fig. 23 is a section made centrally by a coiling device 318, offset from the blocking zones 300 shown at the top of Fig. 22. Therefore, the blocking zones 300 are not visible in Fig. 23. Reference numeral list
