Abstract: PROBLEM TO BE SOLVED: To hold a stable condition under a specified high temperature by providing at least one coating including tin and zinc, and constituting the coating from mixing crystal of tin and zinc. SOLUTION: A parts 1 is a solid bolt, and is provided with a shaft 2 having a fastening part 4, and the fastening part 4 consists of a male screw 3. A head 5 is arranged adjacently to the shaft 2, a welding part 6 is arranged in an end part region which is far from the shaft 2, and the welding part 6 is provided with a conical welding surface 7. The parts 1 is provided with a coating 8 composed of mixing crystal of tin and zinc, the coating 8 is formed in the whole of parts, its thickness is set to 2 to 20 mm, especially, it may be set to about 8 mm. The coating 8 is stabilized at a high temperature, especially, at about 300 deg.C, and the other member is arranged on the fastening parts. As a result, heat treatment of this unit is made possible. Conductivity of the coating 8 is not completely influenced, or it is influenced in an inconspicuous degree, and the parts 1 is used on an electric contact part. Since the material of the coating 8 does not melt in a welding material of a fusing condition, it does not have the influence on the strength of the welding part.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for rivet-connection or punching-out, particularly, precisely performing the rivet-connecting or the punching-out process. SOLUTION: In the method for the rivet-connection of the punching-out by using the rivet-connection or the punching-out apparatus, with which a pick-up device 4 and a male type die guided with the pick-up device, are provided and both can be shifted to a female type die or a working material, and the female type die is connected with this apparatus through a reaction structural body 9, a relative shifting between the pick-up device 4 and the reaction structural body 9 is measured with a first sensor 1 and a relative shifting between the reaction structural body and the male type die, is measured with a second sensor 2, and the depth of the rivet-connection or the punching-out, is adjusted with two measured values. A related device can quickly and accurately detect the working material, or can perform the precise punching-out or the rivet- connection at a constant prescribed depth, regardless of the change of the quality of a material or the other parameter causing the deformation of the reaction structural body 9 during punching-out process.

Abstract: PROBLEM TO BE SOLVED: To provide a method to a remove a pierced rivet mounted to a tubular and axis symmetrical object to be worked and an apparatus therefor. SOLUTION: A punched piece left in a pierced rivet when mounting the pierced rivet is removed by a tool, further, a mandrel with thread is screwed into the pieced rivet while forming a substantially continuous another screw thread. Successively the mandrel is pulled against a pressing force of a receiving base placed on the tool, the pieced rivet is pulled out from the work by the mandrel with the thread.

Abstract: A process and device are disclosed for joining by punching and riveting. At least two layers (4, 5) are pressed by a holding-down clamp (1) against the die-plate (3). For joining the layers (4, 5), a rivet, in particular a semitubular rivet (8), is pressed through at least the layer (4) facing the semitubular rivet (8) by a riveting die (2), is deformed in the lower layer(s) (5), forming a closure head, and is then upset. The holding-down clamp is connected to the riveting die (2) by a coupling unit (6) in such a way that during punching and riveting coupling between the holding-down clamp (1) and the riveting die (2) can be altered between a substantially rigid coupling state and an uncoupled state.

Abstract: The machine has a riveting die in a sleeve. The sleeve is raised until at least an upper cutting edge of a rivet is laid bare, the axis of the die moves along a track concentric around the axis of the rivet. The die is moved towards the rivet parallel to the central rivet axis and widens the upper cutting edge radially, so that the edge conically expands the rivet hole in the upper components and forms the rivet connection.

Abstract: A holding clip (1) has two sprung shanks (4,3) linked at their base (2). The top of the shank bears a head (7,10) separated from a projecting ratchet (8,11) by a gap (6,9). the shanks bend when inserted in a drill hole (15,16), causing the notches to partially overlap and allowing their passage through the hole. An assembly tool may be used which enables the clip to be inserted in eg. vehicle bodywork panels.
