A three position swing cylinder
This three position clamp is applied on automatic clamping on new presses if the surface of the press bed has to be free from clamping tools.
To get signals at automatic and secure clamping if the clamping arm is retracted under the surface and or if the clamping arm is clamping the die, inductive sensors are available.
Proximity switches are optional. These control the clamping arm’s position, assuring correct rotation of the arm to avoid hitting the die.
QDC solution - Here MTR cylinders are installed on a machine together with die lifters and pre-rollers.
