Description

Technical Field

[0001] This invention relates to a method for processing a body. Background Technology

[0002] In the manufacture of housings for electronic devices, it is known that adhesives are used at the seams between housing components so that the housing formed by such joining is as airtight as possible. In this so-called polymer construction and joining technique, the adhesives are used selectively to provide different functions.

[0003] In addition to the previously mentioned function of achieving a seal of the housing relative to a medium such as a gas or liquid, such an adhesive can also be used to specifically dissipate heat from components arranged within the housing, that is, the adhesive supports heat dissipation away from such electronic components.

[0004] Another function of such sealing materials is to shield other electrical devices from electromagnetic radiation that could escape from the housing and affect or damage them. Furthermore, such adhesives can achieve so-called structural bonding of two or more mating components. This structural bonding forms a bond between the mating components, allowing them to be treated as a single element. Different adhesive systems are used to meet different tasks. This means, for example, using epoxy resin, polyurethane, or silicone for bonding. For the adhesive to reliably perform its intended function, it must remain continuously adhered to surfaces important for the sealing function. This required continuous stability is affected by environmental conditions. These include, for example, temperature fluctuations, overall air humidity, and various humidity loads depending on the application area. The environmental conditions of the grasslands differ from those of the North Atlantic coast. Thus, in comparing these two regions, daily temperature variations are significantly different, and overall, that is, humidity loads differ throughout the year, which also applies to the chemical dissolution process of metals. Therefore, the salty air at sea can cause significant dissolution damage to such shells, while grassland environments cause almost no dissolution damage. The following regions present additional challenges in preventing water from entering the shell: these regions experience frequent rainfall, or wading is a real possibility in normal use. For this reason, it is essential to ensure a good adhesive bond between the adhesive and the shell or shell components. To achieve a good adhesive bond, methods have so far included, for example, plasma activation treatment of plastic surfaces at atmospheric pressure. For example, the metal surfaces of the shell have mostly been treated using so-called wet chemical processes.

[0005] To date, commonly used wet chemical cleaning methods typically have only limited cleaning effectiveness. That is, organic contaminants, such as those already mentioned, cannot be completely removed from the surface of the substrate to be cleaned. This type of cleaning also only occurs at the surface, achieving a specific cleaning quality down to a depth of a few nanometers when using non-neutral cleaning agents. A disadvantage here is the associated high equipment costs, not only in the purchase of cleaning chemicals but also incurring additional costs for their disposal. The effect of this type of chemical cleaning is thus insufficient, allowing contaminants in the skin directly adjacent to the surface of a metal substrate, especially cast or rolled skins, to reappear on the substrate surface through existing pores, micropores, cracks, and microcracks that could not be completely cleaned or removed before. This movement of contaminants, if it occurs, is time-dependent. Therefore, these contaminants can re-reach the surface in a relatively short time, thus ensuring a limited seal even after the application of sealant and subsequent sealing of the casing.

[0006] When processing the surfaces of metals with spontaneous passivation properties, such as aluminum, chromium, nickel, titanium, zinc, and silicon, it is desirable to achieve a stable yet reactive oxide layer with as little residual contamination as possible. This residual contamination may be, for example, residues of organic compounds.

[0007] When machining metal surfaces, a particular challenge arises, especially when the spatial orientation of the surface is no longer described by a single plane but extends to all three dimensions of space. This includes, for example, the sealing surfaces of a housing or body, which can be characterized, for instance, by known geometries of grooves and tenons. Compared to the known flat, flange-like sections of a housing, the sealing surfaces of a housing are therefore relatively easily accessible to electromagnetic waves, preferably laser beams, whereas shapes based on the principles of grooves and tenons can only be achieved conventionally on small surface sections.

[0008] As known from the published document DE 10 2011 075 821 A1, the body is heated (warmed) by laser radiation and is thereby primarily cleaned, or the surface or contact surface of the body is melted. The body disclosed therein is a so-called brake disc, as is typical for modern motor vehicles. The surface of such brake discs, or the surface of the brake disc being processed there, is usually flat. Summary of the Invention

[0009] According to a first aspect of the invention, a method for processing a body is provided, wherein the body is shaped such that it has a first flat surface region and at least one additional surface region is formed. Furthermore, a device for providing electromagnetic waves, particularly a laser beam (energy applied by means of electromagnetic waves), is provided. The device has an optical unit, particularly a focusing lens, from which electromagnetic waves are emitted and the surface region is processed by means of the electromagnetic waves. Here, the additional surface region is shaped such that it has an orientation different from the flat surface region, for example, by arching. The flat surface region can be described, for example, in terms of its orientation by a normal vector, while the additional surface region can be described, for example, having at least one region whose surface has an orientation that can be described by a normal vector, wherein the normal vector of the additional surface region or the additional surface region points in a direction different from the normal vector of the flat surface region or the flat surface region. Furthermore, in order to process the flat surface region, the optical unit of the device for providing electromagnetic waves is brought to a position from which electromagnetic waves are projected onto the flat surface region. In this position, for example, the first position, a first angle is set between the central axis of the optical unit, particularly the optical axis, and the perpendicular (normal vector) of the flat surface area.

[0010] To process additional surface areas, the optical unit of the device for providing electromagnetic waves is positioned such that the electromagnetic waves are projected onto the additional surface area from this position, wherein a second angle, different from the first angle, is set between the central axis of the optical unit, particularly the optical axis, and the perpendicular line to the flat surface area. This changed position can also be referred to as the second position. The advantage of this approach is that, to achieve a surface well-processed for the intended purpose, a relatively large proportion of continuously well-processed surface area is obtained. Consequently, the time until the corresponding surface is significantly increased or prolonged due to metal dissolution processes, for example, penetration, is significantly extended. The corresponding housing components, or closed housings, are thus protected from environmental effects for a longer period, particularly concerning the internal protection of electronic components.

[0011] The processing principles mentioned here can include alterations to the coating or layers of the surface area. The processing can also remove components or dirt that are arranged or attached to the surface area. Furthermore, the arches of other surface areas can be shaped to be either concave or convex.

[0012] Here, the shape of the body can be achieved, for example, by bending, and especially by deep drawing. The shape can also be achieved by so-called prototyping, which includes casting, especially pressure casting.

[0013] The body can, for example, have a partially floor-like area, as is provided for a housing portion, such as a housing portion for a control unit of a motor vehicle, wherein the profile-like area is integrally connected to the plate-like area of ​​the body. Such a profile-like area of ​​the body can, for example, be a rib of the body, which serves, for example, to reinforce the body. The profile-like area of ​​the body can also be a rib for another purpose or, if necessary, for other additional purposes. Therefore, such a rib can also be, for example, a rib for forming a seal with a second body (second housing component), or a sealed housing, by arranging a sealing material between the housing component (body, first body) and another housing component (second body, second housing component). Here, the aforementioned profile-like area of ​​the body (first body) can also be referred to as a so-called "tenon." A typical corresponding mating element for the profile-like area (rib, tenon) can be, for example, a so-called groove ("groove and tenon") in the other body (second body). Here, the additional surface area can, for example, partially have an outer cylindrical sleeve shape (e.g., in a design as a tenon). Because another surface area, as part of the profile-like area of ​​the body, can also be constructed as a so-called groove, this surface area can also be constructed as an inner cylindrical sleeve-like surface or shape. Such profile-like areas, whether shaped as tenons or grooves, should extend at least segmentally along the so-called profile line according to this concept of the invention. Here, the profile-like area, whether shaped as a groove or a tenon, has a profile within a corresponding segment of its extension, which extends overlappingly (parallelly) at least for its specific segment within a specific length of the profile itself. This direction of extension is here the profile line (projection direction). An energy application unit for guiding electromagnetic waves to the surface of the body is provided, moving along the profile line. This has the advantage that the energy application unit can be guided or moved relative to the profile at constant intervals, thereby making the quality of the processed surface or the processed surface area more likely to be constant.

[0014] Within the framework of a particularly advantageous implementation, it has been shown that a second angle, differing from the first angle by 10° to 40°, is particularly advantageous.

[0015] According to another aspect of the invention, the device for providing electromagnetic waves is designed to process not only additional surface areas but also flat surface areas, wherein the optical units have the same settings, i.e., the same angular settings. This has the advantage that in this area of ​​the body being processed, only one setting of the optical units and one stroke or turn along the line (travel path) are required, thus eliminating the need for a second turn or second passage through the area. This represents a trade-off between achievable acceptable surface quality and the time required for processing.

[0016] In another embodiment, a surface area is not illuminated, at least not directly illuminated, between another surface area and a flat surface area. Such unilluminated surface areas are, for example, located in areas behind protrusions (edge ​​elements of tenons or grooves), and correspondingly, shielded areas. This type of shielded area is acceptable, especially when this shielded area, not processed by electromagnetic waves, is located in a zone less severely affected by environmental conditions or relatively far from external environmental conditions. Nevertheless, this area, which is shielded from direct radiation in any case and is not continuously directly irradiated (due to roughness), is still illuminated, however not in a continuous and coherent manner: reflections from other, for example, directly illuminated surface areas can result in illuminated shielded areas. This indirect illumination can cause a surface cleaning effect. At surfaces that are illuminated particularly intensely and indirectly (and, depending on the roughness, illuminated only very little directly and discontinuously), it is possible to achieve dispersed, discontinuous melting of surface segments or regions, which is particularly suitable for the tips of the roughness, where heat dissipation is significantly worse than at the valleys of the roughness.

[0017] According to another embodiment, a remelted surface (change of state) is generated in another surface region, and the surface that does not melt (especially does not melt continuously), that is, remains solid (does not change or remains in state), is illuminated. The advantage of this apparent disadvantage is that it allows for the selection of surfaces, or other surface regions, such that the continuously processed surface is particularly large, while the unmelted, solid-remaining surfaces of other surface regions are located where the lack of processing does not necessarily imply a disadvantage.

[0018] According to another aspect of the invention, the surface area is not directly illuminated between the two remelted surfaces of the additional surface area. This apparent disadvantage results in the advantage that a larger, continuous surface area, already illuminated and, in particular, already melted, can be created within the additional surface area, resulting in improved adhesion of the sealant over a significantly larger surface area, while the unilluminated surface area remains in a less damaged position, thus the advantage dominates.

[0019] According to another aspect of the invention, optical units on an additional surface region induce a circular motion of the energy transfer surface of electromagnetic waves, or in particular laser beams. This circular motion is superimposed with a linear motion over a larger area, wherein the circular motion guides electromagnetic waves, or in particular laser beams, from the additional surface region to a flat surface region and back. This design of the method and the motion of the electromagnetic waves has the advantage of enabling particularly thorough surface processing, and furthermore, this particularly thorough processing can be achieved in the first or only processing step.

[0020] To bring another surface area into a particularly advantageous position on the body, the optical unit pivots toward the edge of the body to set a second angle. For the purpose of setting the device so that the method can be executed accordingly, a flat surface area is referenced for setting. Here, it has proven particularly advantageous that the flat surface area of ​​the body is shaped as the bottom of the housing component. Thus, the housing component can be brought into a defined position in the machine with its bottom, flat surface area, and therefore the device can be easily set for the execution of the method. An alternative flat surface area of ​​the body can be, for example, a flange of the housing component, which is correspondingly shaped or already formed. Here, the back side of the flange, i.e., the surface opposite to, or parallel to, the flat surface area, can be received by the machine in a defined position.

[0021] As has already been shown, it is particularly advantageous that an additional surface area is constructed as part of the body's engagement profile, especially as part of a surface area constructed as a groove or as a so-called tenon.

[0022] Here, other surface areas can be, for example, arched outwards (convex), or arched inwards (concave), or have areas where inwardly arched and outwardly arched surface areas alternate. The advantage here is that such designed surface areas have a larger surface area compared to purely straight-extending surface areas, thereby allowing the material change process of the body metal to continue for a longer period.

[0023] For example, there are special design schemes for surface areas in the following situations: the surface area is constructed as part of the profile area so as to, on the one hand, obtain an increased surface area to resist damage caused by the effect of material change and breaking the bonding force, and on the other hand, to improve or enhance the holding force between interacting components.

[0024] Furthermore, a computer program is provided, configured to implement all the steps of one of the methods, or the computer program is programmed such that when implemented on a computer, it implements the method. A machine-readable storage medium is provided on which the computer program is stored, or in other words, a computer program for use in the method is stored on the machine-readable storage medium. Furthermore, a controller is configured such that all the steps of one of the envisioned methods, or method steps, are implemented, or in other words, the controller is programmed for use in the method as envisioned herein. Attached Figure Description

[0025] The invention will be explained in more detail with reference to the accompanying drawings, which are listed below. Wherein: Figure 1 A top view of the body of a housing component, for example, configured as an exemplary controller, is shown. Figure 2 Showing from Figure 1 The cross-section of the edge region of the body, Figure 3 Showing from Figure 1 Another cross-section of the other edge region of the body, Figure 4 Showing from Figure 1 Another cross-section of the other edge region of the body, Figure 5 This demonstrates the motion of electromagnetic waves, or their focal points, on the surface of the organism. Figure 6 The machined flange of the body is shown as an example. Figure 7 The cross-section of the combination of the body and another body is shown. Figure 8 The diagram shows a cross-section of a combination of the main body and another main body at a different location. Figure 9 A controller is shown, which is connected to a device for processing the body 10 via a data transmission line or data transmission device. Detailed Implementation

[0026] exist Figure 1The diagram shows a top view of body 10. This body 10 can be, for example, part of the housing of an electronic or electrical device, particularly a controller for a motor vehicle. This body 10 has, for example, a flat surface area 13. This flat surface area 13 of body 10 can be, for example, shaped or already shaped as a flange 16 of a housing component. The flange 16 has a circumferential shape and, for example, forms one or more abutment surfaces, through which abutment surfaces provide a connection surface for, for example, another body that can also be constructed as a housing component. For this purpose, for example, a sealant can be applied to the flange 16 or surface area 13 to form a sealed joint with the corresponding mating part of the other housing component (see...). Figure 7 and 8 In addition to the flat surface region 13, there exists another surface region 21. This other surface region 21 has a different shape from the flat surface region 13. This other surface region 21 is used, for example, to form a structure (a structure composed of joined parts) by form-locking action or interaction, in conjunction with another body or another housing component, in which, in particular, the shape composition between the bodies plays a role, in addition to the adhesive action between the body 10, the bonded seal or sealant and the other body, such that, for example, if the adhesive force between the body and the seal and the seal and the body is partially lost, the force between the bodies can be transmitted through the existing shape design. Such another surface region can be constructed, for example, as a so-called tenon or a so-called groove, so that the force transmission is feasible through the form-locking in the frame of "groove / tenon connection". In addition, other feasible methods for transmitting force through form-locking are also obtained, which will be described later in this specification.

[0027] exist Figure 1 Different cross-sectional descriptions can be seen in the diagram. Therefore, line II-II shows the corresponding [section]. Figure 2 The diagram shows a cross-section, and the lines, or rather the markings IV-IV, indicate the corresponding... Figure 4 A cross-section of a portion of the body 10. Lines VI-VI show, as... Figure 6 The corresponding description of the cross-section shown is as follows.

[0028] exist Figure 1The image also shows dashed line 24, which, for example, is a type of travel line for a machining apparatus. The apparatus provided here for machining the body 10 should be an apparatus that processes the body 10 by means of electromagnetic waves. In particular, the electromagnetic waves, configured as a laser beam, are projected onto surface region 13 and also onto surface region 21, and are typically redirected such that the electromagnetic waves affect surface regions 13 and 21 within a width 27 (working width). Different schemes can be used to guide the provided electromagnetic waves: for example, there are known oscillations in which the electromagnetic waves are guided such that they induce a circular motion of the electromagnetic waves on surface region 21, and here especially its focal point. This small-scale circular motion is superimposed with a second linear motion over a larger area, wherein the second motion guides one or more electromagnetic waves along a defined line.

[0029] exist Figure 1 Furthermore, the optical unit 30 is shown in four different locations, in principle at two different angular positions. The optical unit 30 can be, for example, a focusing lens 33 from which electromagnetic waves are emitted. The optical unit 30 can have an axis 36, which is oriented, for example, toward and has been oriented, at a position where electromagnetic waves, especially laser beams, are projected onto surface region 13 or surface region 21. The axis 36 can also be, for example, a centrally located axis 36 that can be defined at a mechanical component of the optical unit 30. Thus, the focusing lens 33 can, for example, have a mechanically, especially centrally located axis, which is the same as the centrally located axis 36, especially the optical axis 36. The optical unit is part of a device 39 for providing electromagnetic waves 42. The corresponding device 39 is in Figure 9 It is shown in the middle.

[0030] exist Figure 1 As can be seen, the flat surface region 13 has a specific orientation symbolically indicated by the normal vector n13. This normal vector n13... Figure 1 The point is shown as n13 because the normal vector n13 is directed towards the center. Figure 1 The observer is shown. Reference is made here to the corresponding flat surface region of body 10. Figure 2 And the corresponding normal vector n13. For example, in Figure 1 As can also be seen, the other surface region 21 has this type of shape, such that the other surface region has a different orientation than the flat surface region 13. Figure 1 The orientation shown is symbolically indicated by the normal vector n21 of another surface region 21, which is shown in a direction different from the orientation of surface region 13 having normal vector n13, exemplarily here at the point at the center of optical unit 30. Figure 1Furthermore, it is shown that the optical unit 30 of the device 39 is brought to position P1 to provide electromagnetic waves 42, for example, to process a flat surface region 13. This position P1, which can also be referred to as a first position, is the position from which electromagnetic waves 42 are projected onto the flat surface region 13. For this purpose, in Figure 1 The example illustrates how a first angle α13 is set between the axis 36 of the optical unit 30 and the perpendicular n13 of the flat surface region 13. Figure 1 An angle a13 is set for the optical unit 30 and its position P1, which in this embodiment is a13 = 0° relative to the vertical line n13 (normal vector). Preferably, the position P1 of the optical unit 30 and the axis 36 is "near" the vertical line n13 in order to obtain the highest possible efficiency (high energy density / area of ​​the electromagnetic waves produced). On the other hand, when the angle a13 is not 0°, it is advantageous due to the potential for return radiation into the optical unit 30.

[0031] To process the additional surface area 21, the optical unit 30 of the device 39, which provides electromagnetic waves 42, is brought to position P2, from which the electromagnetic waves 42 are projected onto the additional surface area 21. This additional surface area 21 is visualized here as a rectangle as seen in the top view. The corresponding position P2, which can also be referred to as the second position, is shown in the area below the body 10. For comparison, the position P1 of the optical unit 30 is also shown in this area below. Here, these two positions P1 and P2 are shown for comparison at the same segment of line 24, which here corresponds to a straight line with the same orientation.

[0032] For position P2 between the axis 36 of the optical unit 30, particularly the optical axis, and the perpendicular n13 of the flat surface region 13, a second angle a21, different from the first angle a13, is set. The angle a13 in the first position P1 can, for example, lie in a plane defined by two axes: an axis extending perpendicularly to line 24 and located in the plane of surface region 13, and an axis passing through the perpendicular n13 (normal vector) of surface region 13. From this, position P2 can be defined by angle a21, which lies in this defined plane; see section positions II-II.

[0033] exist Figure 2 It can be seen from the corresponding to Figure 1 The cross-sectional view is shown in Figure II-II. The optical unit 30 is shown here exemplary and schematically in three different locations.

[0034] exist Figure 2Further characteristics of surface region 21 are shown. Surface region 21 shown there has a non-straight, curved curve 38 (in cross-section, a curved profile). This curve has different arches 40, 41. That is, in this case, there is a concave arch 40, and a concave arch towards the protrusion 57 is followed by not only a convex arch 41 but also a concave arch 40. Curve 38 finally ends with another convex arch 41. In other words, the other surface region 21 is partially arched outwards and / or partially arched inwards, or has been arched.

[0035] For example, in the case where a flat surface region 13 is vertically illuminated by the device 39, or its optical unit 30, i.e., the angle a13 between the axis 36 of the optical unit 30 and the vertical line n13 is a13 = 0°, a different second angle a21 should be set such that the second angle differs from the first angle a13 by an angle a21d between 10° and 40°. Figure 2 The diagram shows the angle range a21d, where the difference between angle a13 and angle a21 is represented, meaning a21d = a21. Furthermore, in... Figure 2 The position of optical unit 30 is shown (symbolically) in the middle, where it is pivoted to the maximum extent relative to the vertical line n13 compared to the two other optical units shown. A different second angle a21 of fifteen degrees is shown in this position of optical unit 30.

[0036] For example, by means of... Figure 2 , Figure 3 and Figure 4As can be seen from the diagram, the optical unit 30 has a processing width B30. Within the positions P1 and P2 occupied by the optical unit 30, the device 39 for providing electromagnetic waves 42 reaches not only the flat surface region 13 but also another surface region 21, so that the device 39 for providing electromagnetic waves 42 processes not only the other surface region 21 but also the flat surface region 13. Here, the optical unit 30 has the same position P2. By combining the processed geometry of the surface of the body 10 with the position P2 of the device 39, or rather its optical unit 30, it is possible to obtain not only the illuminated surface, that is, the surface reached by the electromagnetic waves 42, but also, very specifically, the optical unit 30 occupies a position P2 that is offset from position P1, in which position P1 the optical unit 30 is oriented with its axis 36 perpendicular to the surface 13 (plane). During processing, that is, during the method described, due to this different second position P2, a portion of the entire surface of the body 10 is not illuminated. This unilluminated area of ​​the surface is here represented as surface region 45, which can also be called a shielded area or a "dark" area. Indirect illumination of this shielded area can be achieved, as described above. Such surface area 45 can exist at different locations on the body 10. This will be discussed in more detail with reference to the figures described later. By combining the change in position P1 of the optical unit 30 with position P2 and the shape of the surface, not only is there a fully illuminated surface area on which electromagnetic waves 42 are projected perpendicularly or almost perpendicularly, but there is also a surface area 21 that is only partially illuminated.

[0037] Although it is expected that a remelted surface 48 will be formed in another surface region 21 at position P2, surface 51 is also illuminated, which is not melted or remelted, or not continuously melted or remelted, see [reference]. Figure 3 .according to Figure 3 It can also be seen that, in another surface area 21, between the two remelted surfaces 48 between points P1 and P2, or P3 and P4, the surface area 45 between points P2 and P3 is not illuminated. This shaded surface is immediately behind the tab 54. The other, already mentioned, unilluminated surface, as surface area 45, is behind the protrusion 57 between points P10 and P11. As per... Figure 3 As can be seen from the marked surfaces there, there is also a surface 51 (between P4 and P5) between the remelted surfaces 48 (between P3 and P4, or P5 and P6), which, although illuminated, does not melt. Furthermore, for example, in Figure 3In the image, on the right side of the protrusion 57, opposite to the optical unit 30, there is an unilluminated surface, which is designated as surface region 45. It can also be noted that this surface region 45 is located between two remelted surfaces 48 (P8 and P9, or P11 and P12), one of which, in particular, is immediately adjacent to surface 51 (P9 and P10), and this surface, though unmelted, is illuminated.

[0038] According to Figure 4 As can be seen, in accordance with Figure 1 The other contour of section IV-IV is obtained from the same point as for... Figure 3 Similar situations are shown and described. According to... Figure 4 There exists a remelted surface 48 and an unilluminated surface, i.e., a shaded surface, i.e., surface region 45, and an illuminated but unmelted surface 51. Regarding the optical unit 30 and its position P2 and angles a21, a13, and aA21d, and for... Figure 2 The situation described is the same. According to Figure 4 Different surface patterns can be observed. For example, two closely spaced remelted surfaces 48 are revealed, with two unmelted surfaces 51 arranged between them. Between these two surfaces 51, another surface is arranged, which serves as a shielding area for surface region 45. Furthermore, according to... Figure 4 A surface arrangement scheme is disclosed, in which two remelted surfaces 48 accommodate only one illuminated but unmelted or unmelted surface 51 between the two remelted surfaces. The additional surface areas also have concave arches followed by convex arches, the convex arches following the concave arches.

[0039] exist Figure 5 The image shows, with a significantly magnified view, the motion performed by one or more electromagnetic waves 42, particularly a laser beam. As previously mentioned, the device 39, or its optical unit 30, has a processing width B30. Within this processing width, the optical unit 30 induces a circular motion 60 of the electromagnetic waves 42, particularly the laser beam, on another surface region 21. This circular motion 60 is the circular motion of the energy transfer surface of the electromagnetic waves 42 with a small diameter D60. Through this superposition of motions, a spiral motion is generally performed. A second circular motion 63 guides the electromagnetic waves 42, particularly the laser beam, from the other surface region 21 to the flat surface region 13 and back.

[0040] exist Figure 1 , Figure 2 , Figure 3 and Figure 4As can be seen, the body has an edge 66, and the optical unit 30 pivots toward the edge 66 in order to set the second angle a21 and thereby occupy the position P2.

[0041] According to Figure 6 As can be seen, the flat surface region 13 of the body 10 is exemplary shaped as the flange 16 of the housing component 19.

[0042] Figure 7 The diagram shows a cross-section of the assembly of body 10 with another body 10 (housing component, cover). A sealing portion 50 (especially a sealing material) is placed between body 10 (especially its flange 16) and another body 10 (especially its flange 16). Such a cross-section is, for example, at the location marked VI-VI.

[0043] exist Figure 8 The diagram also shows a cross-section of the assembly of body 10 and another body 10 (housing component, cover). An additional surface area 21 with a curved shape is exemplarily constructed and shown therein at both bodies 10. A sealing portion 50 abuts against this curve, the sealing portion having its shape formed therein by a protrusion 57 of the other body 10. The lower body 10... Figure 8 The outline shown corresponds to the groove, and the outline shown on the upper body corresponds to the so-called tenon. Not only the groove but also the tenon is machined in the manner described above, that is, as described with respect to the accompanying drawings. The additional surface area 21 has therefore been constructed, or rather, constructed as part of the profile area.
