Two sets of Qishile NCFC servo press systems are undergoing riveting without rivets in BTM Europe plant
Today,assembly and manufacturing engineers can choose various assembly technologies in the production process,each of which has its unique advantages and limitations.Among them,rivetless riveting(also known as press riveting)technology is widely favored by automobile manufacturing and other industries.Rivetless riveting can connect two or more layers of materials with different composition and thickness(such as metal plate)through the matching function of pressure and material deformation.The assembly process does not need to use gluing or welding,and has the characteristics of low energy consumption and high strength.Unlike riveting and bolted connection,rivetless riveting does not require additional materials,which helps to improve production cost efficiency.

BTM Europe Blechverbindungstechnik GmbH(hereinafter referred to as”BTM Europe”)is one of the leading enterprises in the field of sheet metal connection technology,especially rivetless riveting technology.As a world-famous bending tool manufacturer,BTM was founded in 1966,and its European division,BTM Europe,is an important part of BTM’s global layout.BTM Europe has three locations in Germany-BTM Maschinen-und Steuerungsbau GmbH,located in Brillon,Shoerland,is one of them.
Previously,BTM Europe developed a set of equipment for a German customer for the assembly of transport containers of different sizes.These aluminum containers can be used in hospitals and other places as carts,boxes,crates,baskets or suitcases and other means of transportation.

During the development of rivetless riveting equipment,BTM deployed two sets of Qishile NCFC series servo press systems(nominal pressure:80kN),which have built-in sensors and process monitoring functions for the manufacture of two different containers.BTM rivetless riveting equipment will assemble the top cover and base of the container to the shell.After the container is manufactured,it will become the production component of the trolley.The assembly process involves five metal plates with different thicknesses,and three metal plates need to be assembled in layers.
Previously,in order to ensure that the end customer can safely use this new equipment,BTM has tested and verified the bearing capacity of the assembly in the laboratory.As an electrical engineer,Kevin Rohleder is responsible for the circuit diagram design of new equipment.He said:”The main challenge we are facing is the size of components and the automatic calculation of riveting points.With the help of Qishile’s integrated servo press technology,this rivetless riveting equipment can automatically calculate and set riveting points in a 100 mm grid without being limited by product size.Therefore,compared with the old equipment,the new equipment effectively reduces product replacement time and significantly improves production flexibility.”

Especially suitable for robot arm and other systems
Finally,Hans-Werner Fisch stressed that:
Le is the ideal partner of BTM:Qishile has decades of experience in the development of servo press products,and also has certain international influence.We have used Qishile sensor technology and process monitoring system for a long time in the connection process of functional components such as bolts and nuts.Today,we can provide customers with a comprehensive set of solutions suitable for hybrid connection and other connection processes.Hybrid connection is common in the automobile manufacturing industry,and its implementation needs to be supported by the process configuration file;Only with the help of the servo press system can the set process configuration file be obtained efficiently.
