Hydraulic cushion

The hydraulic cushion has the task of counteracting the force of the main cylinder and thus slowing its descent, allowing the sheet metal to be stretched to create the piece.

It is particularly used for deep drawing processes, i.e. in those operations carried out cold on flat metal sheets to transform them into more or less complex concave shapes.

The hydraulic cushion is placed under the lower fixed table of the press and is composed of a main cylinder, a fixing flange, a mobile table that slides along 4 self-lubricating guides and the stems that pass through the holes of the lower fixed table .

Under the table top, there is an opening door for adjusting the cylinder stroke using the microswitches or encoder (on request).
There is also a safety sensor that prevents damage to the hydraulic cushion in the event of incorrect pressing via the main cylinder and an additional safety sensor placed on the door, which inhibits the movements of the press if it is opened during the cycle. of processing.

Available with force from 20 to 80 tons.
