Fully automated assembly of fasteners in-die

AUTORIV A100 setting heads - automated system for processing of fasteners in-die, under the press in stamping dies and forming tools. The system is suitable for progressive and transfer dies. The setting heads are operated with the A000 feeding unit and controlled via the MDS - ALL IN ONE module. Optional modules are available for evaluation of the force-displacement process and for presence and error detection (PAB head).

Standard models of setting heads: PAN for vertical assembly of clinch nuts, self-piercing nuts and rivet nuts, HRN for stand offs / spacers, FHS for clinch studs, PAB for glide bearings, BPR for rivet ball studs, KOS-HS for clinch studs with guiding part, JAI for snap-in nuts, CNH for horizontal assembly of clinch nuts.

Processing of following fastening elements is available:

Advantages of setting heads

Extremely short cycle time
Since fasteners are loaded parallely to the insertion process, the loading time does not add to the cycle time.

Compact design
Both the insertion head and the feeding system have compact dimensions and can therefore be installed in a space-saving manner.

High degree of automation
All components are designed for a fully automatic, process-safe assembly.

One operation
Self-piercing fasteners (nuts, bushings, bolts) for the processing in one operation without pilot holes (also usable as clinch fasteners with pilot holes) with an optional lead detection.

Good accessibility
Since the A000 feeding unit is positioned outside the danger zone of the tool, it provides optimal accessibility for the operator and the service staff.

System technology from one source
The complete system incorporates the experience and field tested technology from more than 45 years of development time. The innovative mechanics of the system ensure minimal susceptibility to faults.

Technical details

The setting head is placed inside the stamping tool. Depending on the application, several setting heads can be clocked via the tool movement. A supervisory system controls the insertion of the fasteners. As soon as the fastener is in the right position, the insertion process begins. Electrical components and the feeding unit are placed outside the danger zone of the tool.

Further technical information:

  • Coupling and separating the insertion head connection from the tool via central connector
  • Removal and installation of the insertion head as a unit
  • Fixation by means of a fitting system
  • Supply of the insertion head with fasteners via quickly connectable shot tube


The A100 system including the setting heads is designed for the integration of fasteners in-die. The A100 series installation system consists of three main modules:

Feeding cart and controller

  • Hopper
  • Vibrating bowl or step feeder for fastener orientation complete with a level indicator
  • Feed track and in-line level controls
  • Integrated controls with strategically placed sensors
  • Operator interface mounted in a pendant. The touch panel display shows the location of the fault, minimizing down time by reducing the amount of time required for troubleshooting
  • The operator pendent is mounted on a rotating base, allowing the operator to move the display to the most convenient location
  • Fully enclosed cart on lockable castors, making the feeder mobile and capable of feeding multiple applications
  • The cart comes complete with a cover and service doors, reducing maintenance down time by increasing accessibility to the feeding system’s components
  • The fully enclosed cart reduces noise pollution while minimizing dust contamination
  • Pneumatic/electrical Harting plug-n-play connectors
  • Error proofed mechanical connector for fastener charging tube

Umbilical systems

  • Communication between feeding cart and insertion head: signal exchange for the insertion heads and pneumatic line. Connectors are integrated through a multi-pin Harting connector on both ends
  • Fastener charging tube: delivery channel for fastener from feeding cart to insertion head (includes error proof connectors on both ends)
  • Communication between feeding cart and press: signal exchange connector plug on the feeder allows for communication between the press and the feed system
  • The signal exchange ensures that a fastener is in the correct position within the insertion head ready for insertion into the stamping
  • The communication between the press and feed system improves production quality, while decreasing the risc of tooling and/or insertion head damage

Insertion heads

  • Integrated drive and setting mechanism with process signals designed for mounting in-die
  • The insertion head is a module that can be removed as one unit
  • Insertion heads can be mounted in top-down, bottom-up, or at any angle to accommodate a variety of part geometries and tolerances

Functionality of the feeder and control unit - Machine operating sequence

Loading the hopper

Fasteners are placed into the automated feed unit by opening a hopper cover and pouring the fasteners into the hopper.

Moving the fastener to feed position

The fasteners are fed to the top and exit into the in-line tracks properly orientated. A level control at the beginning of the feed rail makes sure that there are always enough fasteners in the in-line tracks. In order to ensure the correct orientation of the nut a mask is integrated into the feed track. Due to the mask check only properly oriented fasteners will reach the in-line tracks.

From the feed position to insertion

Once in the feed position, a blast of air moves the fastener through the charging tube to the insertion head. Upon arrival, the transfer system shuttles the fastener through to the punch position.

Processing of various fasteners

The setting heads are available in several standard models for clinching, self-piercing and riveting fasteners, slide bearings and snap-in nuts. Individual solutions for your specific needs are possible on request.
