The closing (stamping / riveting) process, which constitutes the final stage in the process, of the ball joint body. by permanently forming the upper edge onto a plastic cover or bearing element This is the fundamental operation that ensures leak tightness and operating torque. In the current technology, closing operations on ball joint assembly lines are mainly carried out using two methods. 15 This is implemented using: linear hydraulic pressure application and fixed-angle rotary heads. Traditional orbital coating setups are used. Both approaches are multi-station. It exhibits various technical shortcomings in high-volume production environments. In linear hydraulic systems, the real-time instantaneous force applied along the rolling process is... and monitoring in high resolution is technically difficult. This situation means that the final product is 20 in operating torque values, especially in the starting torque parameter, production batches This leads to standard deviations and negatively affects repeatability on a part-by-part basis. It has an effect. On the other hand, coating with continuous impact characteristics or high friction focus. These methods reduce unwanted thermal stress and microstructural issues on the ball joint body material. This can cause fatigue; this situation jeopardizes long-term fatigue tolerance. 25 It is throwing. In fixed geometry systems, during the positioning of the part within the fixture... The resulting axial shifts, on the order of microns, alter the circular symmetry of the coating edge. This damages the seal and consequently leads to a weakness in the integrity of the watertightness. 2 The subject is asymmetric deformation, the waste rate in post-assembly leak tests. This increases the risk and prevents the surface geometry from being kept within tolerance limits. In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion...
