PJSC Uralmashzavod (UZTM) has completed a unique modernization of a horizontal hydraulic press with a force of 3150 tons, which was carried out for PJSC Revdinsky non-ferrous metals processing plant (part of UMMC) ... The technical re-equipment of the equipment installed half a century ago will significantly expand the range of pipes and reduce the labor intensity of the work performed.
A press for the manufacture of pipes from copper and bronze alloys was installed at the enterprise back in 1968. The tasks that UZTM specialists faced were expanding the range of products, inspection and complete (or partial) replacement of worn parts, updating of control systems, automation and improvement of working conditions at the press. Previously, a press equipped with a direct pressing mechanism could produce pipes with a diameter of up to 250 mm, and due to design changes in equipment and the manufacture of special tools, it was necessary to increase this size to 545 mm.
“According to the terms of reference developed by RZOTsM specialists , we made major changes to the "stuffing" of the press, installed modern systems, manufactured a new tool and, most importantly, equipped the equipment with a back-pressing mechanism. Thus, we were able to combine the two in one: usually direct and reverse pressing presses are two different complexes. The equipment has been successfully tested - the quality of the products meets the customer's requirements, ”said Andrey Vyatkin, Deputy Chief Designer of Uralmashzavod.
According to him, during the technical re-equipment, small mechanization was also introduced: those operations that were previously performed manually are now automated.
