A manufacturing and fixing method of a cover removable from an opening of a metal sheet section comprising the steps: • Defining a perimeter of the opening, • Cutting two cutting lines cutting the perimeter of the opening, a stamping surface being thereby defined between the cutting lines, • Repeating step b) at least three times along the perimeter of the opening, a total of at least four stamping surfaces being thereby defined, • Stamping the at least four stamping surfaces in a direction perpendicular to the plane defined by the stamping surface in such a manner that there are at least two stamping surfaces stamped in opposite senses of said direction perpendicular to the plane defined by the stamping surface in an alternating manner among the stamping surfaces, • Cutting the perimeter of the opening, at least four fixing lugs being thereby defined, • Flattening the fixing lugs located in the section, thereby bringing them back to the starting plane of the stamping surface, • Flattening the fixing lugs located in the cover, thereby bringing them back to the starting plane of the stamping surface in such a manner that at least four connecting surfaces are defined, or on the cover or on the section or on another fixing lug in such a manner that the cover remains fixed to the section without any additional fixing means. And a cover manufactured and fixed according to said method

Provided is a different materials panel structure having reduced occurrence of displacement or warping of a joining section and having excellent external appearance of an outer panel (2). The different materials panel structure has: an outer panel comprising a first metal material; an inner panel (3) arranged on the lower surface side of the outer panel and comprising a second metal material having a higher fusion point than the first metal material; and a rivet (6) comprising the same material as the second metal material and comprising a head section and a shaft section. An outer panel comprises a hemmed section formed by folding a rim section and which supports the inner panel via an adhesive layer (9). The head section of the rivet remains on the outer panel surface. The shaft section of the rivet penetrates from the lower surface side of the hemmed section of the outer panel towards the inner panel. A tip of the shaft section is spot-welded to the inner panel and a protruding section (3a) is provided in the inner panel at a position corresponding to the rivet and protruding in the axial direction of the rivet. A heat insulation section (8) comprising the adhesive layer or the adhesive layer and a gap is formed between the protruding section after welding and the outer panel.

The invention provides a panel assembly comprising: - an inner panel 20 and an outer panel 10, wherein at least the outer panel is a metal panel, the panel assembly is formed by bending a flange portion 12 of the outer panel over a flange portion 22 of the inner panel (hem structure), and - a structural adhesive 30, which is between the flange portions of the inner and the outer panel and adheres the inner and the outer panel together, - wherein the geometry of the hem structure is adjusted to ensure that during further processing of the panel assembly through typical automotive production processes no liquid enters between facing surfaces of the panels and the adhesive.
摘要:
A hemming steel constructed to fold or hem a flange of an outer sheet metal panel onto an inner sheet metal panel has a forming face with a first, generally flat section and a second section inclined to the first section to provide a finished, hemmed flange having an outer portion closed or folded flat onto the inner sheet metal panel and an inner portion adjacent to the fold line which is inclined to the outer portion providing a reduced radius of the fold line bend. The second section of the hemming steel is preferably generally planar such that the inner portion of the hemmed flange is generally flat and provides an outer bend diameter along the fold line of the outer sheet metal panel which is less than three times the thickness of the sheet metal panel and may be approximately equal to or less than the thickness of the outer panel. The reduced bend diameter is believed to provide a smooth and fair fold line which has a more consistent appearance when viewed from different angles to improve the appearance of the panels of the vehicle body in assembly. Further, with the outer portion of the hemmed flange folded flat against the inner sheet metal panel, no sealing operation is required to prevent foreign material from collecting between the flange and inner panel. The angle at which the second section of the forming face is inclined relative to the first section can be changed to allow the location of the peripheral edge of the inner panel to be varied relative to the fold line.

The assembly (10) consists of at least one metal insert (14A, 14B, 14C) and one reinforcing sheet (12). The reinforcing sheet (12) contains reinforcing fibres longer than or equal in length to one centimetre. The metal insert (14A, 14B, 14C) comprises protrusions (22) shaped to traverse the sheet (12), passing between the reinforcing fibres, and to fold by plastic deformation, enclosing the reinforcing fibres when said protrusions are subjected to a longitudinal compression force.
摘要:
Die vorliegende Erfindung betrifft ein Befestigungselement 10 zur Anbringung an einem Bauteil 28, wobei das Befestigungselement eine in einem montierten Zustand an dem Bauteil anliegende Anlagefläche 14 aufweist. Ferner weist das Befestigungselement eine in dem montierten Zustand dem Bauteil zugewandte Aufnahmeausnehmung 12 auf. Die Aufnahmeausnehmung ist durch zumindest eine Seitenwand 16 und einem Bodenabschnitt 18 begrenzt. Die Seitenwand ist zumindest abschnittsweise mit zumindest einer in axialer Richtung des Befestigungselements wirksamen Hinterschneidung 26a, 26b, 26c versehen. Der Bodenabschnitt ist durchbrechungsfrei ausgebildet.

摘要:
Structural members (1, 2) are extruded with their respective abutted edge portions (14, 24) having a transverse cross-sectional configuration complementary shaped with locking tabs and undercut recesses. The tabs (18) of a first member (1) are interconnected by means of a unitary transversally extending and inwardly arcuated web (16), the web (16) being permanently deformed in a joining process by means of a deformation tool (3) forcing the outwardly projecting tabs (18) into a locking engagement with the second member (2).
