6 Method of manufacturing fasteners US109638 1998-07-02 US5957777A 1999-09-28 Jayajit Singh; Naresh Ummat
The invention relates to a method of manufacturing fasteners such as self-piercing rivets, self-piercing studs, plugs, inserts, etc.. In such method a blank is provided and said blank is subjected to a rolling process causing material of the blank to flow radially towards said central axis and axially so as to axially lengthen the blank, with said predetermined geometry of said finished fastener being formed by said rolling process. In addition, a mandrel can be used to precisely define the geometry of the fastener. Fasteners made by the method of the invention are much cheaper than fasteners made by conventional upsetting and extrusion processes. Furthermore, the fasteners made by the method of the invention generally have the advantage of superior grain flow and closer manufacturing tolerances.

16 Forging method of conductive piece JP10252882 1982-06-14 JPS58218341A 1983-12-19 UCHIMOTO KOUKICHI
PURPOSE:To forge a conductive piece of high quality and high accuracy by shifting a pressure punch and a die to the side opposite to a notched groove and deforming a metallic bar between the pressure punch and a fixed knock pin. CONSTITUTION:The inserting part 19 of a knock pin 17 is inserted from the side opposite to the notched groove of a die 11 to the penetrated hole 12 of the die 11, and a metallic bar 23 cut to specified length is inserted into the hole 12 from notched groove side by a guide punch 21. A pin 17 is retreated by required distance by this insertion and fixed at the position P. Under this condition, the punch 21 is replaced by a pressure punch 22, and the end face 22a of the punch 22 is brought into contact with the side 11a of the die 11 to close the notched groove 13 of the die 11. The punch 22 is extruded and moved with the die 11, and the metallic bar 23 is deformed between the punch 22 and pin 17, and a conductive piece 14 in which a flat plate is attached to the end of solid handle 15 is formed. Then, the die 11 is elastically returned to an original position by a spring 27, and the conductive piece 14 is pushed out from the die 11, by the pin 17.
17 Manufacture of composite contact or rivet die JP860082 1982-01-22 JPS58125331A 1983-07-26 NUMAI YOSHINORI
PURPOSE:To prevent generation of burrs, and to make the thickness of a contact metal uniform, by treating under heating a prism-shaped composite contact material in a nonoxidizable atmosphere of a prescribed temperature, before forming said material and finishing it to a rivet die. CONSTITUTION:For instance, a prism-shaped composite contact material 2 is manufactured by cutting a composite contact bar material 1 which has clad a contact metal 1b on both the upper and lower surfaces of a base metal 1a, and furthermore has clad a contact metal 1c on both its upper and lower surfaces. Subsequently, this contact material 2 is treated under heating at a temperature of 300-500 deg.C in a nonoxidizable atmosphere. Subsequently, preliminary forming is executed by collapsing the upper half part of the contact material 2, and thereafter, it is finished and formed to a rivet die.
18 Manufacture of rivet type composite electric contact JP9497081 1981-06-19 JPS57209739A 1982-12-23 NUMAI YOSHINORI
PURPOSE:To form a rivet type composite electric contact with less amount of plastic working and improve durability of a header working die by sticking a strap for contact on the vertical side of a strap base material having T-shaped sectional form, cutting it to a specified length and making header working. CONSTITUTION:A strap base material 6 having overturned T-shape sectional form is manufactured by extrusion and drawing. A contact material 8 is then stuck on the outer face of vertical side 7 of a strap base material 6 to form a composite contact strap material 9. This is then cut to a specified length to form a composite contact piece 10 of T-shaped solid. The composite contact piece 10 is then worked with a header to form a rivet type composite electric contact 11 having an arcuate contact face. Thus, amount of plastic working is very little and the die for header working is not damaged.

A forged rivet for joining dissimilar materials includes a disc-shaped head and a shank. The shank includes: a first shank portion extending from the head; a ring-shaped protruding portion that protrudes outward at the lip of the first shank portion; and a second shank portion, the cross-sectional area of which is smaller than the first shank portion and which extends further in the direction of the tip from the protruding portion. On the surfaces of the shank and the head, surfaces that contact a light alloy material when the rivet is driven into the light alloy material, a coating film with a higher electrical resistance than steel is formed.
