Press Brakes, High Tonnage

A range of high tonnage press brakes, from 600 to 1500 tonnes is available in India from Accurpress International Sales. The basic structure of the Accurpress consists of side frames, bed assembly, ram, double rocker arm assembly, and a torque tube. The heavy torque tube, welded to the double rocker arm assembly, synchronises the hydraulic cylinders to maintain ram parallelism. The power ram tilt adjustment optimises ram trim to match various tooling characteristics, or for doing fade out work. It is easily adjusted via push buttons located on the operator control station. An eccentric shaft running through the left side connector rod of the Accurpress will rotate when powered, and will tilt the ram to the desired location. Ram and bed crowning is carefully machined into every Accurpress in order to minimise die shimming for parallel bends. Press brakes which are designed with flat or no crowning will deflect out of parallel under load, which necessitates time consuming shimming. The heavy I-beam bed design on the larger tonnage models greatly reduces bed deflection for optimum forming quality. This design also eliminates the need for a below-the-floor bed on the 600-tonne models.
