BRV-Series
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.

Punch slide with pneumatic tool opening directly from the manufacturer Baust
The BRV series from Baust combines precise punching technology with sophisticated design for industrial applications. A punch slide with pneumatic tool opening enables the punch and die to be quickly separated using a pneumatic cylinder. This allows new strip material to be easily fed between the tools without the need for time-consuming manual intervention.
Baust develops and manufactures all components at its site in Germany. The robust design, weighing around 350 kg, ensures stability at production speeds of up to 80 m/min. Companies in the metal industry, printing industry, and plastics processing rely on this technology for continuous perforation in steel, aluminum, and plastic webs.
Fast tool change thanks to pneumatic tool opening in the punch insert
Modern manufacturing processes require flexibility in changing batch sizes and product variants. The punch insert with pneumatic tool opening significantly reduces set-up times, as a pneumatic cylinder with 6 bar operating pressure automatically moves the tools into the change position. Punches and dies can be exchanged in a few minutes.
This design minimizes downtime and increases overall equipment effectiveness. Companies benefit from lower inventory levels because small batches can be produced economically. The patented mechanism keeps the tools synchronized throughout the entire changeover process so that punching can continue immediately after closing.
Achieve production speeds of up to 80 m/min with the BRV punch insert
The BRV series processes material thicknesses from 0.2 to 0.8 mm with strip widths between 20 and 100 mm. With a tensile strength of up to 550 N/mm², the punch insert with pneumatic tool opening is suitable for demanding materials. The tolerances comply with ISO 2768-1 c.
Strip speeds of 60 to 80 m/min enable high output rates with consistent precision. The compact design, with a width of approximately 370 mm and a height of 560 mm, allows integration into existing production lines. Baust supplies suitable service parts and special tools for specific hole patterns and applications.
Patented rotating mechanism for permanently synchronized tools
A key unique selling point of the BRV punching inserts is the patented rotating mechanism. It ensures that the upper and lower tools work in permanent synchronization. After opening for a tool change or coil replacement, the components immediately engage with each other again with precision.
This design extends the service life of the tools and reduces wear. Baust supports users with individual consulting, project planning, and engineering services.
