＊ The uniﬁcation of die thickness is conditions for the clamp use.
If it is not uniﬁed, contact Pascal.

Swing clamp

model

The clamp rod swings and prevents theinterference at time of load/unload of die.

Determine the size and quantity of the clamp in such a way that the total clamping force, i.e. clamping force by quantity,
must be higher than the value stated below.
It should be better for stamping operation to increase the number of the clamp by lowering the force for each clamp,
rather than decreasing the number of clamps raising the force for each.

The total clamping force,i.e. clamp force by quantity

Crank press＞： 10% of machine tonnage

High speed press ： 20% of machine tonnage
Hydraulic press： die opening force

For tonnage 1100kN crank press
If 4 pieces of model TXA040 (clamping force 39.2kN) are installed on both of slide andbolster, total clamping force would be 156.8kN (39.2 x 4), which represents about 14%of machine tonnage.

The proper size and quantity of clamps diﬀers depending on the condition of die and machine.
Please contact Pascal sales representative or customer center for the details.

Pascal control system

For the control system supplying the hydraulic pressure to the Clamp and Die-lifter, the compacted Control unit model HCS isrecommended. For the manual operation, please select the Non leak valve unit model VHA(operated manually) and Power unit
model HUT.
