Short project description:

For our customer SWD Stator- und Rotortechnik, based in Densbüren, we realised a universal plasma welding facility for the manufacturing of stator and rotor laminated sheet packages for the automotive industry.

The electric sheets are positioned in the facility and then pressed and measured by a servo press module. During this measuring process, the number of sheets is determined and shown to the operator on the touch-screen display. Once the measuring process has been completed successfully, the package is welded according to the desired product parameters.

The welding process is completed with a maximum of 6 plasma burners (internal/external) using a G-code that is generated from the specified product parameters. In the product database, the data for the individual packages can be saved, modified and reloaded as required. The data of the welded sheet packages is saved in an SQL database with all relevant process values.
