Insertion unit with automatic feeder SBM25

for blind clinch nuts

Overview
Automatic system for inserting blind rivet nuts and blind rivet bolts in industrial assembly applications. Designed for reliable, position-independent installation with automatic feeding and short cycle times. Suitable for round and hexagonal shanks with process forces up to 25 kN. WEBER system components are adapted to ensure process reliability and integration into automated production lines.

System capabilities and process description
WEBER offers an automated inserting and feeding system for blind rivet nuts and studs. The insertion head supports high-precision pre-alignment of hexagonal fasteners and an optional automatic mandrel change. The feed and control systems are matched to the process. Docking-capable interfaces enable flexible use of multiple fasteners or tools and robot integration.

Key product features

• High-precision pre-alignment of hexagonal elements to the workpiece
• Suitable for fixtured or robotic applications with optional docking interfaces
• Automatic ejection/removal of defective fasteners or detection on component faults
• Process monitoring with motor encoder plus displacement and force sensor technology
• Standard quick-change system for DIN mandrel; optional automatic mandrel changeover
• Operable in all working directions—access from one side only required
• Reduced downtime via automatic mandrel change and drift-pin functions
• Cycle times from approx. 5 s possible to enable automation
• Mechanical design optimized for more than 7 million cycles under full load

Additional functional highlights

• Laser-based high-precision alignment of fastener and workpiece for reliable positioning
• Automatic ejection of faulty fasteners to safeguard process quality
• Interfaces and docking capability for multiple tools/fasteners and robot integration
