摘要:
The invention relates to a method for creating an electrically conductive connection between an electric terminal device having a cavity, such as a cable shoe, and a sheet metal part. According to said method, a hollow fixing element is riveted to the sheet metal part to prevent torsion, thus producing an electrically conductive connection between the fixing element and the sheet metal part and the assembled component is then provided with an electrically non-conductive or poorly conductive protective coating, such as for example a lacquer coating or powder coating. Said method is characterised in that a receptacle for the electric terminal device is configured in the vicinity of the front face of the fixing element, to which the electric terminal device is attached, said receptacle preventing the torsion of the terminal device in relation to the fixing element and the sheet metal part and that a thread forming or cutting screw is screwed through the cavity of the electric terminal device into the hollow fixing element, said screwing action forming or cutting a thread. The invention also relates to a corresponding fixing element and an assembled component that is produced in this manner.

A functional element having a functional portion, a generally tubular rivet portion and a ring-like sheet metal contact surface is characterized in that features of shape are provided at the rivet portion for co-movement of the sheet metal part during the formation of the rivet bead, in particular at the free end of the rivet portion and/or at the radially outer side of the rivet portion, at least in the region adjacent the free end of the rivet portion. A component assembly comprising a functional element and a sheet metal part as well as a method for the attachment of a functional element to the sheet metal part are also claimed.

The invention relates to a method for producing hollow body elements (200), for example, nut elements which are applied to components which are normally made of steel (280), in particular, for producing hollow body elements having an essentially quadratic or rectangular external profile (202). Said method consists of cutting individual elements of a profile in the form of a profile rod (1) or a winding after holes (204) have previously been stamped in the profile, a threaded cylinder (206) is subsequently, optionally, formed using a follow-on composite tool (10) which consists of several working stations. The invention is characterized in that a penetrating process and a punching process are carried out in the working station. The invention also relates to hollow body elements (200), components, follow-on composite tools (10) and rolling mills (600, 602).

摘要:
A method for providing an electrically conductive connection between an electric terminal device having a cavity and a sheet metal part. A hollow fixing element is riveted to the sheet metal part to prevent torsion producing an electrically conductive connection between the fixing element and the sheet metal part. The assembled component is then provided with an electrically non-conductive or poorly conductive protective coating. A receptacle for the electric terminal device is configured near the front face of the fixing element, to which the electrical terminal device is attached. The receptacle prevents the torsion of the terminal device in relation to the fixing element. The sheet metal part and a thread forming or cutting screw is screwed through the cavity of the electric terminal device into the hollow fixing element to form or cut a thread. The invention also relates to a corresponding fixing element and an assembled component.

摘要:
A fixing element comprising a fixing section and a tubular stamped or riveted section in which the stamped or riveted section enable the fixing element to be placed on a metal part and the fixing section enables an object to be placed on the metal part. A bearing surface on a transition region between the fixing section and the stamped or riveted section extends in a radial or conical manner and optionally has torsional fixing features. The tubular stamped or riveted section free front end has a conical cutting surface which is divergent on the radially inner side in the direction of the free front end area and a rounded impact and traction surface on the radially outer side. The cutting, impact and traction surfaces meet at an annular edge on the free front end of the stamped or riveted section and are shaped to prevent shavings from occurring.

An element attachable to a sheet metal part by riveting, having a shaft part and a head part. The head part has at its side con-fronting the sheet metal part a ring recess which merges at the radially inner side into a cylinder section of the head part which merges into the shaft part and into a tubular rivet section which surrounds the shaft part in the region of the head part. The head part is disposed within a contact surface arranged radially outside of the ring recess and merges at the radially outer side via an at least approximately conical wall into the ring-like contact surface. At least one local recess and preferably a plurality of in particular uniformly distributed local recesses is or are provided in the conical wall of the ring recess and/or in an optionally present base surface of the ring recess.

The invention relates to a rivet nut (10) with a base part (12) and a cylindrical rivet section (14), the base part having a central threaded cylinder (16), an annular contact surface (18) that is coaxial to the threaded cylinder in a plane (20) perpendicular to the longitudinal axis (22) of the threaded cylinder, and that has an axially aligned annular groove (24), said groove being arranged radially inside the annular contact surface and radially outside the cylindrical rivet section and said groove blending, on the radially inner side, into the outer surface of the cylindrical rivet section, and antirotation ribs (42) being provided in the area of the annular groove. The invention is characterized in that the annular groove, when seen in an axial cross-sectional plane, has a U-shaped cross-section with a radially outer lateral wall (30) which is relatively steep and which has, at the steepest point (33), an inclination to the center longitudinal axis of the rivet nut in the range of approximately 45° to approximately −20°, preferably of approximately 30° to approximately 0°. The volume of the annular groove is chosen in such a manner that across a range of sheet thicknesses adapted to the respective thread size there is room for the volume of the respective folded region of the rivet section inside the annular recess (80) that is formed by molding the sheet part (60) into the annular groove of the element and that it does not project beyond the side (82) of the molded sheet facing away from the annular contact surface.
