A blind rivet setting device and method of setting a blind rivet. The device includes a housing; a pulling mechanism, arranged in the housing, that includes a chuck housing movable in a pulling direction and clamping jaws movable along a clamping distance in the chuck housing; an electric drive, structured and arranged to act on the chuck housing, that includes a control device; an electric battery structured and arranged as an energy source for the electric drive; and a spring structured and arranged in the chuck housing to apply a force to clamping jaws. For each clamping jaw, the chuck housing includes a guide path with a path base obliquely oriented to the pulling direction, and a back of each clamping jaw is supported against its respective path base over the clamping distance.

A feed assembly for a foot-pedal operated riveter and a method of using the same is disclosed. The feed assembly includes a rivet stop that has a tip that separates a lowermost fastener from a second from lowermost fastener when the riveter is in a non-operational position. This rivet stop prevents fasteners from sliding down a raceway on the feed assembly. When the riveter is moved into an operational position, the rivet stop moves out of the way and permits the second from lowermost fastener to slide into position for subsequent installation. The rivet stop thus enables automatic reloading of the riveter during operation.

A different material joining structure has: a first panel made of a first metal material; a second panel made of a second metal material that has a higher conductivity than that of the first panel, is different from the first metal material, and at least a part of which faces the first panel; and a rivet for joining the first panel and the second panel, wherein the rivet is made of the first material, and includes a head portion that is embedded in the second panel in a non-penetrating manner and a bottom portion that abuts on the first panel, and wherein a nugget portion as a joint portion is disposed between the first panel and the bottom portion, the nugget portion being formed by resistance welding the rivet to the first portion with the rivet disposed between the first panel and the second panel.

A mounting unit includes a mounting part for a mating surface of a basic structure which cannot be welded to the mounting part and a welding element fixed in a through-bore of the mounting part. The welding element corresponds to the bore and has a thickness at least as large as the mounting part. An annular groove is formed in the welding element. A part of the welding element bounding the groove on the outside forms a form-locking connection element expanded outward and fixing the welding element in the bore by a form-locking connection toward the mounting side. A central region radially within the annular groove is a welding surface for the mating surface, is aligned with or protrudes beyond a mounting-side edge region of the bore with an overhang and is aligned with or projects over the form-locking connection element. A production method is also provided.

A method for joining at least two structural parts includes a fitting step in which a joining element is driven into the first structural part while a residual material thickness is maintained, and a joining step in which the joining element driven into the first structural part is connected to the second structural part. The joining element has a hollow element shaft, which is driven into the first structural part, and an element head, which is welded or adhesively bonded to the second structural part.

A system and method of joining at least two workpieces together using a friction rivet and a friction rivet cap that are friction stirred together after a cutting tip or cutting feature on the friction rivet cuts through workpieces and is then bonded to the friction rivet cap, and wherein the friction rivet cap may be excluded if the friction rivet includes a hollow in the cutting tip, the hollow being flared after the friction rivets cuts through the workpieces to thereby create an integral rivet cap in the end of the friction rivet.

A battery disclosed herein includes: electrode bodies: an outer package which has an opening and which houses the electrode bodies, a sealing plate which seals the opening of the outer package and which has a through-hole and a recessed portion provided around the through-hole on a surface of a side opposing the electrode bodies; and a sealing member which seals the through-hole of the sealing plate. The sealing member has an inserted portion having been inserted to the through-hole and an enlarged diameter portion which extends from the inserted portion to inside of the outer package and which is formed with a larger diameter than the inserted portion. At least a part of the enlarged diameter portion is arranged inside the recessed portion of the sealing plate.

A localized annealing process and a part having localized areas with increased ductility produced by the process. The part is formed of hard material, tempered, and/or otherwise hardened such that it meets minimum hardness and ductility requirements. The part further includes localized areas that have increased ductility for workability, which could include various types of deformation. The localized annealing process includes providing a part with low levels of ductility and then annealing localized areas of the part for increased ductility that will need to be machined or attached to another formed part. The annealing process includes placing an electrode on either side of the localized area and generating electricity through the localized area. The material in the localized area is then heated from the electricity to form a more ductile physical structure.

The purpose of the present invention is to, after a through-hole is formed in a plurality of members between which a sealant is applied, rapidly and easily remove the sealant flowing into the through-hole. This through-hole forming method is provided with: a step (S2) in which a cutting tool rotates about the axis thereof, thereby forming a through-hole in a plurality of members between which a sealant is provided; and a step (S4) in which after the through-hole is formed, the cutting tool continues the rotation about the axis thereof for a predetermined time or a predetermined number of rotations, thereby removing the sealant flowing into the through-hole.
