In hollow riveting, a connection between two sheets is created in a multi-stage setting process by punching in a hollow rivet, which creates a form-fitting connection. The rivet has a shear tensile strength of over 7.6 kN. The use of four rivets per component creates a high-strength connection. \ use of hollow punch rivets offers several advantages over welding. On the one hand, the speed of production can be increased in the joining process. On the other hand, the quality of the connection increases, as the reproducibility is significantly higher and the need for any reworking falls away. The new connection technology will replace the welding of the connectors and the rail fasteners. After final load-bearing capacity tests in a certified testing laboratory, the introduction is imminent,\In addition to hollow punch riveting, an alternative method to the traditionally used weld-in nuts was also sought, which serve to simplify assembly. They are used wherever installation is difficult due to limited accessibility. HS Anlagentechnik uses rivet nuts, which have a similar principle to blind rivets. With the help of a battery-powered setting tool, the rivet nut is pulled into the component. Due to a faster and more even setting process, the quality of the nuts is significantly higher. The final improvement can be found in the attachment of the head guide. To avoid a welded-in suspension system, the In the future, HS Anlagentechnik will increasingly rely on hollow punch rivets HS Anlagentechnik now also relies on rivet nuts, which have a similar principle to blind rivets %u00a9 cpi-worldwide%u00a9 cpi-worldwide
