Definitions
- TITLE Method of manufacturing a tubular element and tubular element thus obtained.
- the present invention relates to a method of manufacturing a tubular element. It will find, for example, its application to constitute a front crossmember of a motor vehicle, designed deliberately hollow, so as not only to transversely reinforce the passenger compartment of the vehicle, but also to facilitate the installation of an air conditioning unit, in particular , and advantageously define one or more air ducts, such as defrosting the windshield and / or ventilating the passenger compartment of the vehicle.
- the sleepers of this type are constituted, in a known manner, by at least two half shells assembled together by means of two external longitudinal edges facing each other, coming from the two half shells, these longitudinal edges being joined together by specific means of mechanical connection, such as stapling, rivets, welding points, etc. ...
- the object of the present invention is to remedy these various drawbacks by proposing a method which is simple in its implementation and inexpensive.
- the invention relates to a method of manufacturing a tubular element, in particular a front cross member of a motor vehicle, capable of constituting at least one air duct, of the type comprising at least two half shells assembled on two external longitudinal edges. vis-à-vis, by punctual means of mechanical connection, characterized in that it also incorporates, the production of sealing means of said tubular element which are constituted by at least one continuous deformation, convex or concave, carried out simultaneously on each of the external longitudinal edges facing the two half-shells, in the vicinity of the mechanical connection means.
- FIG. 1 is a schematic representation in cross section of a cross member of a motor vehicle integrated into a dashboard
- FIG. 2 is a cross-sectional view of a cross member according to a first embodiment
- FIG. 3 is a schematic cross-sectional view of a cross member according to a second embodiment which may correspond to that of FIG. 1
- FIG. 4 is a view on an enlarged scale, in perspective of the assembly and sealing area of a cross member according to one of the examples of FIGS. 2 or 3.
- the method according to the invention applies to the manufacture of a tubular element in general.
- the method allows the production of a front crossmember 1 of a motor vehicle, which moreover is capable of constituting one or two air ducts.
- the cross member 1 constitutes a first defrost duct 3 and a second ventilation duct 4 whereas, according to a simplified example, shown in FIG. 2, the cross member only an air duct 2.
- the invention applies equally to one or the other of the cases.
- the cross-member 1A is constituted by two half-shells 5 and 6, assembled together by means of two external longitudinal edges 5a, 6a - 5b, 6b, made opposite and constituted in fact by extensions of the sides of the half shells 5 and 6. These are arranged relative to each other to define the air duct 2.
- the method according to the invention includes, in addition to the mechanical connection means which have just been mentioned, the production of sealing means 8 associated with said point mechanical connection means. These consist of at least one continuous deformation, convex or concave, carried out simultaneously on each of the external longitudinal edges 5a, 6a - 5b, 6b, facing each other, of the two half shells 5 and 6. These means of sealing are advantageously made in the vicinity of the mechanical connection means 7.
- sealing means 8 could be associated with any mechanical connection means, provided that they are punctual, are advantageously preferred mechanical connection means obtained in particular by stapling, by mechanical deformation known as "clinching" so that the continuous deformation, concave or convex 8, of the lateral edges 5a, 6a - 5b, 6b can be obtained simultaneously with said mechanical connection or clinching means 7, during a single stamping operation, while separating their respective function sealing and assembly.
- the concave or convex sealing deformation 8 produced on each of the external longitudinal edges 5a, 6a - 5b, 6b, of the two half shells 5 and 6 is obtained by means of a stamping punch, in particular in V (not shown), deforming said edges simultaneously to obtain two profiles 8a, 8b fitting perfectly together and of shapes corresponding to that of the punch.
- such a deformation provides, in addition to the desired tightness, increased rigidity in this zone, since the deformation 8 also constitutes a rib.
- the two half shells 5 and 6, constituting the tubular element or cross member 1 are obtained by stamping a sheet of steel, aluminum, magnesium, or other materials, in particular metallic, according to determined profiles and complementary.
- the tubular element 1A is a front crossmember of a motor vehicle, the half shells 5, 6 and an intermediate element 9 constituting it are shaped so as to define two air ducts 3 and 4, independent of one another, for example one for defrosting, the other for ventilation.
- Figure 3 differs essentially from that of Figure 2 in that an intermediate element 9 is interposed between the half shells 5 and 6, these edges ends 9a, 9b coming between the edges 5a and 6a on the one hand, and the edges, 5b, 6b, on the other hand, half shells 5 and 6.
- cross member 1A according to FIG. 2 comprising a single air duct 2
- cross member 1 according to FIG. 3 comprising two air ducts 3 and 4
- said cross member is designed so as to also receive any type of equipment such as, for example, an air conditioning unit 10, a speaker 11, etc.
