The hydraulic locking die-holder allows to change the dies faster than a standard mechanical one. The system is composed of the hydraulic locking die-holder and a lift arm to remove the pieces.
This system allows to replace the whole set of dies placed in their cassette-plates, reducing press downtime to few minutes.
The whole operation of die changing is managed and controlled from a PLC step by step. The system can be installed on all existing presses also of other brands.
How the die-holder works
The die-holder follows these automation phases:
- the hydraulic cylinders unlock setting the holders free
- a hydraulic cylinder pushes the cassette-plates on the plate of the die lifting arm placed at the entrance of the work area on specifically-dedicated shelves
- once the cassette-plates have been released, the arm lifts and takes them out of the press to be changed.
The die lifting arm is activated manually, with or without the help of locking brakes. Alternatively, it is automated with hydraulic movement.
