Presses

The machine can control several process parameters and through these can manage the logic of defect pieces or generate statistical analysis with the recorder values.

The most important parameters are:

1. Temperature of the billets to be loaded: a stable temperature of the billets grant a a constant forging quality and has direct influence on all other forging parameters.
2. Coring punches penetration time: it is a good marker of the correct execution of the forging process, being directly connected to the energy required by the piece during the whole penetration stroke.
3. Punches real penetration force: gives information similar to the coring punches penetration time, and is influenced by the same parameters.
4. Final position reached by each punch: it is the most important parameter to judge if a piece is good or must be scrapped. Excess or lack of material are actually influencing this position, as well as loaded billet with not-correct temperature.

The ME Series machines have all features to be competitive in a controlled, modern forging plant, and perform best on medium and small production batches. These machines can be equipped with gas, or even better with induction furnaces, and with these are suitable to forge diversified materials: brass, aluminium, steel, copper, titanium. As an optional, dies thermoregulation units can be integrated with the machine.

Hydraulic presses are, by their nature, slightly slower than mechanical units of equal strength but have been designed to reduce batch change time. In particular, the system is equipped with the following features:

1. Detection of the piece unloaded by means of piece weighing: a sensitive cell housed on the unloading arm weighs the molded pieces and discriminates if the ejection operation has been successful. The system is simple, robust and allows to set the correct weight value for each piece according to the recipe. No adjustments or cleaning is necessary for photosensitive elements.
2. Automatic adjustment of the penetration depth punches also during forging: changing the drilling depth is not a problem, a hydraulic system controlled by an encoder allows the centesimal adjustment of the position of the punches.
3. Change dies and punches in a single automatic package: the fixed drilling tool makes it possible to change die and punches in a single operation, the machine automatically cuts the dies and inserts the pins.
4. Heating of mdies and external punches in shade with respect to the production: being able to change dies and punches in automatic allows to heat them during the forging operations carried out by means of hydraulic presses, that is in shade with respect to production time. This feature saves more than half an hour for each die change.
5. Adjustment of the pressing force of each press and of each individual punch: the press and each individual punch have adjustable forces and speeds within wide margins, this allows to find the correct motion law for each material and for each die.
6. Detection of the force exerted by each individual punch for pin damage detection: load cells in the pins provide for the detection of the real force exerted by the punch. This makes it possible to detect piece scraps due, for example, to the punch break, or allows adjustment of the punch energy in order to minimize machine consumption.
