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 accumulator gets the surplus of oil coming from the power cylinder. E-mail : [email protected] This drawing belongs to Quiri.

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 UNIT The cam receives the oil from the power unit and transforms it into the piston speed. The temperature rise causes oil volume dilatation. At rest, the expansion makes the cam's piston go out of about 10% of the total stroke. The force equals the product...

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 of the cam piston rod. Example : If the load at the end of the cam's piston is higher than the available load, the oil volume coming from the power unit goes in the accumulator. The safety block limits the pressure to a maximum of 400 bar and allows you...

4. CONCEPTION RULES (important to read) • The temperature rise causes oil volume dilatation. 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 be taken by the die and not by the cam unit’s rod Define the accumulator according to the power unit Take care of the oil drain access Leave enough room to screw the connections Take care of the cam system kinematics (see the figure). In order to keep the position’s...

5. HOW TO CHOOSE THE COMPONENTS OF YOUR HCS 5.1. General rules Power unit Safety block Cam unit The CAM UNIT is defined by the required force and stroke. The POWER UNIT (diameter + stroke) is defined according to the cam unit force and stroke. The ACCUMILATOR (volume) is defined according to the power unit’s volume. The diameter of the hoses is defined according to the press speed and the type of cam unit. E-mail : [email protected] This drawing belongs to Quiri.

The required stroke can be defined according to the following draw: Total stroke Used stroke Position rod inside system cold Position rod inside system warm 5.2. Example n°1 (see tab. 5.4) Cam unit definition : Needed force : 6 T => Needed stoke : 35 mm => Choose a 7 T Cam unit Choose a cam unit with a stroke of 50mm (useful stroke : 38 mm) The chosen cam unit is 7T force and 50mm stroke TYPE : N07.050 Power cylinder definition (see the shady part of the tab.) The power cylinder as a diameter of 63mm and a stroke of 80 mm Accumulator definition (see the shady part of the tab) The accumulator...
