Belt-driven Press Brake

July 8, 2011

The E-Brake from Safan produces pressing force by the use of synchronized electric motors through belts and pulleys to the beam, eliminating the need for hydraulics.

The absence of hydraulics means there are no seals or pressure valves that need to be replaced, resulting in less downtime and lower maintenance costs, the manufacturer states. Also, this press brake uses less energy than hydraulic machines because the motors operate only when the beam is actually moving.

This pulley-block system pulls the top beam of the press into the die and applies the pressing force evenly along the length of the machine. When rolling the belt up, the driving motor pulls the beam downward into the die. The return springs, strained during the bending procedure, return the beam to its initial position.

Pressing tonnages are available from 35 to 300, and bed lengths are available between 1,250 and 4,100 mm.

Depending on size and power requirements, the number of pulleys varies. The largest machine has four pulley-block arrangements each with their own drive and nine pairs of rolls. With this machine a 100-mm-wide belt is used.  The belts are 3-mm-thick, wire-strengthened material coated with polyurethane.
