Overview: The document provides technical specifications and features of a numerically driven welding head, specifically the TN type, used in resistance welding processes. It highlights the integration of advanced technologies for precise control and efficiency.
Specifications:- Welding Force: Supplied by a brushless servomotor with torque monitoring to ensure constant force during welding.
- Force Monitoring: A Piezo sensor can be installed for force checking during the welding cycle.
- Welding Current Control: The current can be switched off once a defined position is reached.
- Direct Drive System: Utilizes a ball screw with an integrated position measuring device for adjusting approach and squeeze speeds.
- Electrode Holders: Adjustable in X-Z axes, mounted on a moving and current conductive block for easy adjustment and quick interchangeability without stopping water flow.
- Tool Integration: Features an indexing slot for tools and easy integration onto aluminum standard profiles.
- Adaptability: Allows for adaptation of lower electrode movement and mounting into assembling machines.
Technical Data:| Head Type | Max. Welding Force (daN) | Stroke (mm) | Electrode Holder Diameter (mm) | Electrode Diameter (mm) | Overhanging Arm Width (mm) |
|---|
| TNB 20 | 20 | 50 | 12 | 3 | 70 |
| TNC 60 | 60 | 50 | 16 | 8 | 100 |
| TND 150 | 150 | 50 | 25 | 12 | 125 |
Graphical Data: The document includes a graph illustrating the relationship between time, motor's instruction, flow of the welding current, and welding force, marking the end of the welding cycle.
