Voith is launching a new generation of punching systems with its integrated HDE high-performance punch system. The HDE was developed specifically for punching, nibbling and forming applications in the high-end segment. It offers convincing performance with high dynamic behaviour and precise control mode.
The high dynamic behaviour of the HDE is based on newly developed valves as well as intelligent hydraulic and electronic control circuits. With a punch stroke of 4mm, the new punch system achieves a cycle time of just around 18ms. Thanks to the new directly controlled, electronic copy valve, or direct electronic copy valve (DECV), control of the HDE is extremely accurate. Direct actuation by a servo motor gives the valve very fast and highly precise impulse response. The HDE achieves a repeatability of up to 0.01 mm, permitting high-precision bending and forming processes. Moreover, the valve is designed to be rugged, compact and very flexible in terms of interfaces – integration into the machine or system could not be simpler.
The load-controlled two-pressure-system with separate supply circuits for low pressure and high pressure assures an optimal power balance in the system, which can reduce energy consumption by up to 60%.
