Recent Patents in Riveting and Applications
Riveting is the most common method of assembling sheet metal parts which are widely used in the assembly of aircraft and other areas. The rivet can be divided into two types: manual and automatic. There are many parameters associated with a riveting process that directly affect the quality of rivets including squeeze force, rivet length, rivet diameter, and hole diameter tolerance. So its very important that each component of a rivet has high reliability and precision to ensure the stability during the riveting process. This paper reviews various recent patents in the key components of both types of rivets and various applications. The patents reviewed concern a period extending from the years 2000 up to date. The applications concern mainly both types of integrated rivets covering the area connected with the production of aircraft, auto and other industrial mechanism using modernization that has reached by material replacing, geometry, and embedding additional units into main design The list of patents reviewed is by no means complete or extensive it shows however the extent of the subjects covered in patents in this area during the last five years. The paper concludes with a description of the future developments expected in the subjects covered.
