What exactly is rivet/blind rivet technology?

GESIPA® makes it clear


GESIPA® blind rivet technology has come to be an essential part of many modern industrial production processes requiring joining technology owing to its high levels of成本效益和多功能性. It combines a number of advantages in one solution, providing access to the blind side in an application, reliably joining a wide range of materials with lasting effect, including more sensitive ones, and documenting the setting process where required.

Blind rivets come ina wide range of forms, materials, shapes, lengths and even colours. Depending on the application you have in mind for the blind rivet, you can choose to order a standard model for delivery straight from the GESIPA® warehouse or choose to have a blind rivet designed especially for its intended use.

GESIPA® blind rivets – terminology

A blind rivet consists of two parts: thehollow rivetand themandrel body.The hollow rivet has asetting headand arivet body.The setting head is located on the processing side and is available with a range of diameters and in different forms. The head variants are as follows:dome head,countersunkandlarge flange. The rivet body comes in different lengths that will depend on the thickness of the material to be riveted. The job of the mandrel body is todeformthe rivet body. It has apredetermined breaking point, at which the mandrel body breaks off once the rivet has been deformed sufficiently. Thefilling sectionis the portion of the mandrel body that is left behind in the hollow rivet. The spent mandrel is the portion of the mandrel body that is removed from the set rivet using theblind riveting tooland disposed of.

During thesetting process, the mandrel body is moved using the setting tool jaws, deforming the hollow rivet until it is firmly positioned in the component as predefined. In the end, the mandrel body breaks off at the specified point (the predetermined breaking point) and can be disposed of via the recycling system. The rest mandrel is the spent mandrel left behind in the hollow rivet and can provide an additional locking function depending on the application in question.
