DMG Meccanica employed pneumatic solutions by Aventics in two machines developed for automotive industry automation. In order to solve a safety issue in a shed winding and inserting machine for the production of electric hybrid motors, engineered to handle and move huge alternator stators of hybrid buses, DMG installed a portal equipped with LU6 cylinder with pneumatic locking unit by Aventics, used as a braking device ensuring machine safety in fall-preventing function.
In case of power failure or breakdown, the cylinder stops the moving stator, with excellent time-reaction, protecting the machine and braking a mass of about 200 kg. To ensure short cycle times in an alternators head forming machine, developed for a customer in the transports sector, Aventics AV03 valves have been also employed, new generation valves in plastic material more compact by 45% and lighter by 50% compared to traditional metallic valves. Reduced weight and size allowed to minimize rotation table inertia, ensuring the rotation speed requested by the final user.
