Applying the PLC control technology to the old electrical upsetting machine s stepping sequentially control unit, which consists of relays, contactors and solenoid valves.

Intelligent Control of Embedded Electric Upsetting Machine;

The author decribes the thinking of reforming electrothermic forging machine with programmable controller.

Selection of the parameters of electrical upsetting process for valve based on artificial neural networks;

Because the electrical upsetting process for valve is complex,the parameters of this process are mostly defined by experience.

To meet the market demand, and on the basis of referring similar products at home and abroad, a new automatic cold header for making steel ball is developed.

therefore, it was proved that the monitoring for the multistage cold header producing producess withupsetting force was reasonable and feasible.

ased on the requires of the monitoring of the cold header producingprocess, A piezoelectric pressure transducer, which is simple onconstruction and convenient on installation, is designed.
