Clinch Press for Manual Fastener Installation
Operator-based processing of self-clinching fasteners
The A220-CP is a manual clinch press for the installation of clinch nuts, studs and other self-clinching fasteners.
As a stationary work station, this C-frame clinch press is suitable for production processes that require an operator. This machine is ideal for smaller quantities and the production of single parts. The feeding of the clinch fasteners can be done either by a feeding system or manually.
The design of the press machine is similar to the A240-CP robotic work station with the difference that the processed sheet metal component is placed by the operator and is not held by the robot.
Processed fasteners: clinch nut, rivet nut, self-piercing nut, clinch stud, self-piercing stud, rivet stud
Fastener thread size: M5, M6, M8, M10, M12
Working direction: from top to bottom
Advantages of the Clinch Press
- Process-reliable processing of clinching fasteners
- Parallel drive (patented) for efficient tool movements and low wear
- Low compressed air consumption and active tool protection
- Active tolerance compensation (patented)
- Feeding system and controller module are placed outside the danger zone
- Integrated displacement measurement system with active pre-stroke before the setting stroke
- Process monitoring with force-displacement evaluation
Functionality
In the start position, all machine components are in the home position. The clinching fastener is supplied by the feeding system or inserted manually into the holder. Next, the component is positioned correctly with both hands and, if necessary, held in place if the operation is activated via the foot switch.
In automatic mode, the setting process is started and performed automatically with the two-hand operation or foot switch. The plunger moves onto the component at reduced speed.
Both keys of the two-hand operation must be pressed during the entire setting process. If a key is released, the plunger stops. When activated via the foot switch, the component is held with both hands during the setting process. The foot switch is not released until the setting process is complete.
The plunger moves back to the home position after the fastener has been installed. When all fasteners have been set, the operator removes the sheet metal component.
Automatic mode
The fasteners are pressed in during automatic mode. The movements are not triggered until the corresponding release signals have been transmitted to the assembly system.
Manual mode
In manual mode, adjustments are made on the press machine. In this operating mode, movements can be activated individually.
Process safety
The clinch press is positioned in such a way that the operator can easily and safely reach all operating elements so that no dangerous situations can arise. The two-hand operation is positioned approx. 500mm away from the danger zone.
Components
Emergency stop (1)
In dangerous situations, the emergency stop button is actuated. This immediately stops the clinch press and all machine movements.
Two-hand operation (2)
The setting process is started using the two-hand operation. To do this, both keys must be pressed and held down.
Foot operation (alternative) (3)
The setting process starts by pressing the foot switch. After completion of the setting process, the foot switch is released.
Pneumatic maintenance unit (4)
The pneumatic maintenance unit (hidden in the picture) checks, maintains and regulates the incoming compressed air. The pressure regulator can be used to adjust the incoming pressure and shut it off if necessary.
Control cabinet (5)
The control cabinet contains the electrical and pneumatic control elements. The assembly system is switched on and off via a main switch on the control cabinet.
Controller module (6)
The clinch press is operated via the controller module. The control panel can be mounted on the side of the C-frame press, on the assembly cell or on the feeding system. In addition, a process evaluation is possible via the software of the control module. A force-displacement curve of the entire setting process is recorded and evaluated.
See A240-CP robotic work station for central components of the press machine.

Further Designs
Manual work stations for other fasteners
Manual work station A220-BI for blind rivet nuts and studs
Variant with working direction from top to bottom (2)
The setting process is similar to A230-BI mobile robotic tool. The processed sheet metal component is inserted by the operator and the setting unit is moved to the component.
Variant with working direction from bottom to top (3)
The setting process is similar to A230-BI, except that the processed sheet metal component is placed on the setting unit by the operator, the setting unit is not moved to the component.
Manual work station A220-NMS for combination of a nut and spacer (4)
The nut-spacer-combination is a high-strength structural connection for joining positions accessible from one side, e.g. in closed profiles.
This manual clinch press is used to set clinch nuts / rivet nuts in combination with additional spacers / washers in a single step. The spacer is inserted into the die by a transfer mechanism with gripper. The operator places the component on the inserted washer. The plunger feeds the nut and performs a setting stroke that connects the clinch nut and spacer to the component.
