All rights reserved. May 2004 Print : F024089 2. HOW THE HCS WORKS When the press-die goes down, the upper part of the die drives in the piston rod of the power cylinder. Oil is pushed through the hose and pushes the cam unit’s piston rod out. When the press goes up, the cam unit’s piston goes back thanks to the two gas springs, and the oil is pushed back to the power cylinder. The...

All rights reserved. May 2004 Print : F024089 3. ELEMENTS OF THE HYDRAULIC CAM SYSTEM 3.1. POWER CYLINDER The power cylinder transforms the speed of die into oil flow going to the cam unit. The power cylinder’s capacity is bigger than the cam unit’s one. The additional volume allows compensation due to the oil compression and the dilatation. The oil surplus goes to accumulator. 3.2. CAM...

All rights reserved. May 2004 Print : F024089 3.3. ACCUMULATOR It is necessary to use an accumulator with a hydraulic cam unit system. The accumulator gets the surplus of oil coming from the power unit. In case of problem, its capacity allows to by-pass the oil moved by the power unit. Its inflating pressure limits the maximal pressure in the cam unit. Also, it limits the force at the end...

At rest, the expansion makes the cam's piston rod go out about 13mm. This fact must be foreseen during design · The stroke of the power unit must be strictly shorter than the guided height of the upper and lower part of the die · The radial forces must...
