The hydraulic presses, because of their nature slightly slower than the corresponding mechanic units, are designed to reduce the set-up time. In details, the machine is equipped with the following features:
1- Unloaded parts control by means of parts weighing: a highly sensitive loading cell mounted on the unloading arm take care of the weighing of the forged parts and assess if the ejection operation has been done with success. The system is simple, sturdy and allows the setting in the die recipe the correct weight value for each piece. The cleaning and adjustment operations of the light sensors are therefore no longer necessary.
2- Automatic regulation of the punches penetration stroke, during the forging operation too: to modify the coring depth is not a problem, an hydraulic system controlled by encoders allows the centesimal regulation of the punches position.
3- Dies and punches change in a single automatic package: the fixed coring tool allows to change in one single operation the die and the punches, the machine does automatically the locking of the die and of the coring tips.
4- Heating of the dies and punches out of the machine, during the production: to change in automatic the dies and the punches allows to heat these even when the machine goes on producing other parts, without consuming production time. This feature allows to save more than half an hour for each die change operation.
5- Regulation of the die closing force and each punch force independently: the press and each single punch that can be programmed in a wide range, to find the correct material flow effect for each alloy and for each die.
6- Control of the force generated by each single punch, to identify the eventual damages on a coring tip: loading cells are transmitting the real force generated by each punch during the forging operation. This lead to the identification of defected pieces due for example to the rupture of the coring tip, as well as to regulate the energy of the punch to minimize the machine consumption.
