Punching units for extra fast and precise tool changing

Shorter production runs, less inventory, make-to-order processes – A clear trend in the sheet metal industry which the Baust Stanztechnologie with the BRV series absolutely corresponds. The punching units are available as a coil-driven version or a powerful servo drive variation.

The coil-driven BRV punching unit

In the fully mechanical version, the punch slot BRV is driven by a coil. If the user wants to change the coil, a compressed air cylinder moves the tools so far apart that the punches and dies are out of engagement. This allows the new coil to be easily placed between the tools. A quick change of the punching tools is also possible in this position. Another peculiarity of the coil-driven BRV is the patented turning mechanism. It is arranged in such a way that the tools remain permanently synchronized. The result: the tools can be easily closed pneumatically and continue the punching process directly. At line speed of 60 m/min and more.
