A hydraulic lock die holder permits much quicker die changes than a standard mechanical one. The system is made up of hydraulic lock die holders and a die lifting arm.
Hydraulic cylinders are released, freeing the holders, a hydraulic cylinder pushes the holder on the die lifting arm place located at work area entrance on dedicated shelves.
When the holders are freed, the arm lifts and moves the holders outside the press to be replaced.
This system lets the entire die group in the holders to be replaced in a single operation, reducing downtime to just a few minutes.
The entire die change operation is managed and controlled step by step by a PLC.
The system can be applied to all presses, existent ones and even other brands.
The die lifting arm is manually driven with or without the assistance of parking brakes or hydraulically in automatic.
