PRESS AND FORGING EQUIPMENT
MODERNIZATION
Press and forging machinery bearing the trade mark of NKMZ is well known in
the CIS and abroad operated in steel making and other industries. The machinery
covers a variety of hydraulic presses of 5.000; 10.000; 15.000 and 30.000 tp,
the world's largest hydraulic stamping presses of 65.000 and 70.000 tp,
forging of 10.000 tp, hammers with impact energy of 400 and 630 kJ and
dropping parts weighing between 16 and 25 tons respectively, the unique
no-anvil hammer with 1.500 kJ impact energy, etc.
Due to the rather long service life of these machines
(20 to 30 years in average), the necessity has arisen to update
and modernize them.
Thus, one of the major tasks in production of the press and forging equipment
is modernization of the machines made earlier in order to impart them some new
commercial qualities.

- Presses proper.
- Improving the die block rigidity;
- Updating the frame crosshead guides;
- Extending the service life of sealings employed in the main and
auxiliary sealings.
- Mechanization of auxiliary processes:
- Raising the press reliability and saving the auxiliary operating
time.
- Automation of the hydraulic control and synchronization systems:
- Designing and implementing the NC-supported electric and hydraulic
systems of a new generation in order to expand production
capabilities based on the advanced technologies.
Modernization of the high-powered die-forging presses is being carried
out by retrofitting their drives and implementing the process control and
diagnostic systems.
In some cases the facilities used for farther powering of the hammers
and presses do not meet present-day requirements with respect to their
responsiveness, reliability and load-carrying capacity thus requiring
implementation of modernization programs.
Tube forming presses, in particular, may be retrofitted by providing,
with the containers rated at higher molding pressures, updating driver
and control systems employed for isothermic molding.
No-anvil hammers require stronger rams fitted with the advanced control
systems, etc.
At present, NKMZ's engineering and production capabilities enable to
modernize any kind of the press and forging equipment considering the
ever growing requirements for their cost effectiveness, automation level,
reliability, safety, etc.
