Feeding and setting head for press tools

The A100 setting head is a fully automatic assembly system for progressive dies and transfer dies. The setting head is installed in the press to set fasteners into sheet metal parts during the pressing process.

Finished parts can be produced directly under the press in punching and forming tools. This eliminates many downstream operations and the need for intermediate storage of components.

Your benefits

  • Fully automatic, reliable processing of fasteners under the press
  • Very short cycle time and good accessibility in the press
  • Processing in thin sheets, thick sheets and plastics in one operation
  • Flexible processing directions - from above, from below and in angular positions
  • High degree of automation thanks to system technology from one company
  • Process monitoring of the fasteners in the feeding system

Processing of following fastening elements is available:


  1. Applications
  2. Angular positions
  3. Use of a gas spring
  4. Components


Punching heads for various fasteners

The punching head is available in several designs. Thus, different types of fasteners can be processed:

  • Clinch nuts, rivet nuts, self-piercing nuts - Setting head PAN
  • Horizontal assembly of clinch nuts - Setting head CNH
  • Clinch studs - Setting head FHS
  • Clinch studs with high cycle times - Setting head KOS-HS
  • Spacers / washers, standoffs - Setting head HRN
  • Glide bearing bushings - Setting head PAB
  • Bolt-shaped fasteners - Setting head BPR
  • Clips - Setting head JAI

Customized solutions for your special requirements are also possible:

  • Adaptation to a special fastener
  • Adaptation to a special tool environment
  • Individual application direction and fastener delivery
  • Adaptation to the workpiece to be processed and the required component depths

Use of a gas compression spring

Tolerance balancing for optimum pressing results

1. Gas compression spring; 2. Press tool; 3. Setting head; 4. Stipper pad with cutout for the setting head; 5. Die

Normally, a press operates in a path-controlled manner. Without tolerance balancing, certain factors, such as the height tolerance of the fastener, the thickness tolerance of the sheet metal and the setting of the press, will result in different pressing results.

If the setting path remains the same, the fasteners will be deformed by too high a press-in force and will not be sufficiently pressed in by too low a press-in force if these factors are not taken into account. A gas pressure spring in the press provides the necessary tolerance balancing and prevents different results.

Advantages of a gas compression spring

  • Constant results and consistent quality of the sheet metal joint
  • Easier work for the press operator
  • Significantly faster commissioning and reduced downtimes
  • Increased productivity and thus lower costs per piece
  • Spring compression - the punching head is not damaged by repeated pressing due to operator error

Angular positions

and difficult installation situations

It is often necessary to place fasteners in angular positions to meet difficult installation situations.

On request, we can also offer special solutions for the installation of fasteners in hard-to-reach places, in tight installation spaces or at specific angles,

such as:

  • Clinch nuts at an angle of 60 degrees
  • Combination of clinch nut and spacer at an angle of 90 degrees to the working direction

The automation system consists of these components:

  • Setting head for integration in the upper part or in the bottom part of the press tool
  • Mobile feeding system with up to four shot hoses per conveyor unit, placed outside the tool

Signal exchange
Signals are exchanged between the feeding system, the controller and the setting head. The data exchange secures the operating status "fastener in press-in position". This sends a release signal to the press. Without a release signal, the press stops. The signal exchange between the press and the feeding system increases process reliability. In automatic mode, tool damage can be avoided. All signals are transmitted from the setting head to the feeding system via a multifunction hose.

Setting head
The active part of the setting head contains the plunger and the press-in mandrel for inserting the fastener into the sheet metal part. In all positions in the punching head, there is a direct query of the fasteners, such as "fastener in press-in position". The passive part of the setting head is the connector plug for the multifunctional hose and the shot hose.

The complete punching head can be quickly replaced as a compact unit. The setting head is connected and disconnected from the tool using a central connector.

Punching heads can be installed and operated top down, bottom up or at an angle. The working direction depends on the part geometry and tolerances.

Feeding system
The feeding system for press applications can consist of one or two conveyor units. With one conveyor unit, up to four setting heads can be controlled, with the same fastener on all setting heads. With two coupled conveyor units, up to eight punching heads can be controlled, with one type of fastener per conveyor unit.

We have conveyor systems with step conveyors or with conveyor bowls. For feeders with two conveyor units, the two conveyor systems can be combined.

    • Belt hopper and jam section with fill level control via sensors
    • ALL IN ONE controller module with touchscreen, rotatable design
    • Housing on fixed castors with doors
    • Upper lid for filling the belt hopper with fasteners
    • Pneumatic and electric Harting plug-and-play multifunction connectors
    • Shot hose in various lengths for transporting fasteners
