Enormous forces are applied when special-purpose machines are used to form and swage heavy wire sections. Schmale Maschinenbau GmbH relies consistently on servo gearboxes made by WITTENSTEIN to do the job.
With their absolute power and power density, our TP+ 4000 HIGH TORQUE planetary gearboxes are the ideal choice for this press. 530 millimeters in diameter and 540 millimeters long, they transmit torques up to 40,000 Nm highly dynamically in a very small space envelope. Four of our units are installed altogether in the double swaging press – two for the pre-swaging process and two for finish-swaging. The huge torques involved here could previously only be attained using hydraulic drives. The benefits of servo technology – such as lower running costs, higher operating efficiency, up to 15 percent more productivity and better energy efficiency – can now also be leveraged for this application. In combination with regenerative rectifiers, energy consumption is up to 73 percent lower.
