BRUDERER Stamping presses

In the sheet metal, stamping and forming industry, BRUDERER stamping presses are synonymous for maximum performance, utmost precision and unsurpassed reliability. Our BSTA range includes high-performance stamping presses with press forces from 180 to 2500 kN and a stroke speed range of 100 to 2000 spm. The unique lever system of the BSTA stamping press distributes the load acting on the ram in the system. This load distribution, the minimal bearing clearances and the efficient lubrication system are the main reasons for the long life and consistently high precision of the BRUDERER high-performance stamping presses.

BRUDERER Feed Units.

The feed units developed by BRUDERER allow for the highest possible accuracy, even for complex production processes. Mechanically or electrically driven versions, suitable for different raw materials.

The strip feed units of type BBV, BSV, BZV and VGB provide the ideal link between stamping press and punching tool. The ingenious drive concepts impress with their absolute step accuracy throughout the power range – the basis for the production of high-quality punched parts. Their unrivalled reliability and suitability for universal application optimise productivity whilst delivering maximum efficiency.

Servo feed BSV.

These electrically-driven servo feed units are characterised by high flexibility and accuracy. The areas of application are virtually limitless, thanks to the freely programmable axes. They are most effective in complex production processes with a high level of automation. The dual-feed version of the BSV 75T is particularly suitable in two-track applications for the parallel advancing of two raw material strips. Furthermore, the BSV servo feeders are ideal for feeding forward profiled and pre-stamped strips.

Roller feed BBV.

These entirely mechanical units have been epitomising precision and reliability for decades. They are driven by the main shaft of the punching press via a cardan shaft angle-synchronously to the strip feed unit. The feed works with oscillating rollers to generate the feed movement and with clamping bars that hold down the strip during the punching process. The feed length can be set steplessly, either manually or motor driven. The strip lifting device allows the accurate release of raw punching materials for optimum performance of the centring pins in the stamping tool. The punching press’s central lubrication system manages lubrication and cooling.

Gripper feed BZV.

This gripper feed unit is characterised by outstanding performance data and unrivalled reliability. It is driven by the main shaft of the stamping press via a cardan shaft to the strip feed unit.

The strip clamping with grippers is the ideal solution for feeding forward thin, sensitive and refined raw materials. Due to the linear gripper movement there is no rolling motion of feed rollers on the strip. The grippers are easy to exchange and allow perfect adjustment of the gripper contact area for profiled and pre-stamped strips. The punching press’s central lubrication system manages lubrication and cooling.
