Self-piercing riveting system for joining light weight materials.

Objective



This project describes a new joining method for lightweight constructions for example in the automotive industry. Based on the self piercing riveting process already known for about 15 years two new concepts are introduced to the process. The idea of the "thermal self piercing riveting" is to heat the adherends partially at the joining region until they can be deformed. Following this first step the actual process of self piercing riveting will be carried out. The idea of the "high speed self piercing riveting" (HS self piercing riveting) is to carry out the process of self piercing riveting with a higher speed of cutting and deformation in order to reduce the joining forces.

The objectives of the project are:
- The joining of materials that are hard to deform like refined steel, magnesium alloys, semi strong aluminium materials and plastics as well as coated materials and mixed combinations;
- The reduction of the joining costs by 30% through several measures mainly by the reduction of the joining forces;
- The reduction of the weight of the self piercing riveting equipment by 20% to make the use manufacturing robots more economic.
