Abstract

A self-piercing rivet with a concave lower surface is disclosed and includes a barrel having a cutting edge formed on an insertion tip and a head is formed on an opposite end of the barrel from the insertion tip. The head includes a concave inner surface, or a recess, that includes a peripheral edge radially aligned outboard of a cylindrical outer surface of the barrel adjacent the head. An assembly is disclosed that includes at least two panels that are joined by one or more self-piercing rivets that include a head provided having a concave inner surface. A peripheral edge is configured to form a contact ring that has continuous contact with the outer surface of the first panel to form a closed arcuate recess between the barrel and the periphery of the head.

Description

technical field [0001] The present disclosure relates to self-piercing rivets for joining components and forming a peripheral depending seal about the periphery of the head of the rivet when installed on a panel. Background technique [0002] Self-piercing rivets are used to join two or more components usually supplied in sheet form. Self-piercing rivets are ideal for joining dissimilar materials, which may include fiber-reinforced composites, advanced high-strength materials, and other lightweight materials. [0003] Some assemblies may include various laminations of different high strength or brittle materials. Available self-piercing rivet designs include countersunk head rivets with closed heads ( figure 1 ), tubular rivets ( figure 2 ) and flat head rivets with closed head ( image 3 ). [0004] Insertion of rivets into brittle materials can create small cracks in the material, which can reduce the strength and durability of the riveted assembly in the direction o...
