Automated Assembly Solutions: Self-Piercing Rivets

Portariv® Pierce Riveting Equipment

The Portariv® pierce riveting equipment consists of three modular assemblies: power pack and control system, head assembly and feed assembly. Two modular standard systems are available: a high-volume system which can be equipped with a process monitoring system, and a medium-volume system that combines performance with compact design.

The installation systems are adapted to specific production processes - from operator-actuated systems to automated assembly lines. Riveting modules and lower dies of the head assembly can be engineered into different configurations to accommodate difficult accessibility conditions or to assemble large or awkwardly-shaped components.

Due to their short cycle times, these systems provide a very efficient working process, reducing assembly times to a minimum. They are especially cost-effective for medium- and large-volume production.

  • Cycle times between 2.0 and 5.0 seconds under normal operating conditions, dependent on feed tube length and cylinder stroke
  • Hand-actuated or robot-mounted systems available
  • Flexible integration into existing production lines
  • Multi-head and other custom modules available
  • Vibratory bowl feed system and proprietary pneumatic components ensure reliable feeding
  • Increase of productivity
  • Ensures a quality joint
  • Can be equipped with a process monitoring system to record each rivet placement in real time
   

  



Assembly Applications

Air cargo equipment
The shoulders and corner stiffenings of this air cargo transportation pallet are joined with Fastriv® countersunk pierce rivets. Due to the large dimensions of the pallet, the C-frame is supported on a gantry system.

All rivet positions are manually driven. A hopper system feeds the rivets automatically. The elimination of drilled holes and automatic feeding of rivets have reduced cycle times significantly.

Construction components
Steel lintels up to 2 meters long are assembled on a customized 2-head riveting machine. The placement of the rivets is staggered left and right at a distance of 30 cm (11.81"). At the ends of the lintels, rivets are placed parallel to each other. Twin bowl feeders allow the system to be fully automated, resulting in increased productivity.

These heavy-duty lintels can carry loads up to 45 kN (10,000 lbs). The Fastriv® pierce rivet system produces the high strength joints required for this critical application and does not damage the coated sheets.



Automotive space frame
This space frame is assembled with Fastriv® pierce rivets and a lightweight C-frame. This C-frame has a throat depth of 850 mm (30") and can be manipulated with a robot due to its low weight of 140 kg (310 lbs). This C-frame is used for all rivet positions.
Traffic/street signs
This compact Portariv® system features a C-frame with a throat depth of 600 mm and can assemble signs of various sizes and with different numbers of Fastriv® joints. To get a flat surface, Fastriv® self-piercing rivets with countersunk are used because after assembly the signs are laminated with foil. Key benefits are cost and time saving due to elimination of drill/punch and screwing operations.
