摘要： An apparatus and method for fastening dissimilar metals like steel and aluminum utilizes a steel rivet and a spot welding machine. The rivet and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the rivet to penetrate the aluminum and weld to the steel layer. The fastener may be used to join stacks with several layers of different materials and may be used to apply a threaded socket or stud made from steel or titanium to an aluminum or magnesium alloy structure. Layers of non-conductive materials like plastic and ceramics may also be affixed to a conductive layer using the fastener made from a compatible material that extends through a pilot hole.

摘要： An apparatus and method for fastening dissimilar materials like steel, plastic and aluminum. A resistance welding fastener having multiple layers may be used with or without a sealant. The fastener may be used to form an aluminum covered steel laminate via a hemming pattern of attachment. The fastener may have a solid shaft or have an extended reach and have features for interacting with the welding electrode. A variety of electrode tips may be employed to cooperate with the fastener.

摘要： Provided is an element that allows being rigidly joined to a metal plate without adding a shape difficult to machine (a shape required for joining) in advance. An element 1 includes a flange-shaped part 2 and a columnar part 3 having a smaller diameter than the flange-shaped part 2. In a state where the columnar part 3 is inserted into an insertion hole 12 drilled in the metal plate 11, by applying pressure in an axial direction to deform and flow the metal plate 11 in a compression direction at the flange-shaped part 2 and to deform a part at a distal end edge of the columnar part 3 to expand in diameter to receive a deformed and flowed metal, so as to allow the element 1 to be joined to the metal plate 11 made of metal.

摘要： A self-clinching fastener for attachment to a plastically deformable metal substrate includes a body portion with a central axis, the body portion has an annular-shaped surface extending in a direction perpendicular to the central axis The annular-shaped surface includes a first annular face, a second annular face, and a third annular face. The third annular face lies on an imaginary horizontal plane. A punch portion extends from the body portion. A plurality of spaced apart lugs encircle the punch portion. The first annular face extends from an outer peripheral surface of the punch portion in a radially outwards direction, and the second annular face is radially disposed between the first annular face and the third annular face. One of the lugs declines to the second annular face.

摘要： A piercing nut according to the present invention includes an internal thread 11, a ring-shaped punching part 12, a ring-shaped groove 16, and a bearing surface 17. The internal thread 11 is formed at the center of a nut main body 10. The ring-shaped punching part 12 protrudes around the outer periphery of the internal thread 11. The ring-shaped groove 16 is formed around the outer periphery of the ring-shaped punching part 12. The bearing surface 17 protrudes around the outer periphery of the ring-shaped groove 16. The height h of the ring-shaped punching part 12 is equal to or lower than the height H of the bearing surface 17 in the opposite manner to the conventional technique.

摘要： An apparatus providing mating alignment between internal threading of a rivet nut and the external threading of the mandrel of an unclaimed installation tool before anchoring the rivet nut in a hole in a substrate, or the external threading of an unclaimed threaded fastener after anchoring in the substrate hole. The improvements include a bushing sleeve seated in a counterbore in the rivet nut, for guiding the external threading of the mandrel or fastener to the internal threading of the rivet nut. The sleeve also enables play during upset of the rivet nut, and provides visual confirmation whether the rivet nut has been properly anchored in the hole of substrate.

摘要： A rivet element for setting a thread into at least one component has a head portion which can be interlockingly brought into abutment with the component and a sleeve portion which can be inserted into an opening extending through the component and can be plastically deformed. The sleeve portion is provided with an internal thread into which a traction mandrel and/or a screw element can be screwed. The sleeve portion has a protruding rib structure on the outer circumference, the rib structure having at least one first support rib and at least one second support rib which extend in the longitudinal direction of the sleeve portion and are separated from one another by a recess. After the plastic deformation of the sleeve portion, the support ribs contact one another in order to allow a direct force flow between the head portion and the sleeve portion.

摘要： A method of producing a press-fit connection and to such a connection between a component and a fastening element. A head of the fastening element is pressed into an unpunched component without piercing it. A form fit acting in the axial direction is formed between the head and the component by material forming. For low press-in forces, the head has a central area projecting in the axial direction.

摘要： A multi-material boss, configured for fastening of a fastener thereto, being a feature of a the cast part, comprising a boss cylinder, an augmenting cylinder, and a filler metal layer is provided. The boss cylinder is made of the same material as the die cast part having a first hardness, and has a first interior. The augmenting cylinder is made of an augmenting material having a second hardness, is fixedly secured in the first interior of the boss cylinder, and has a second interior defined by a second cylindrical shaped wall, a base rim, and a second opening. The second hardness is greater than the first hardness.
