Russian pipe maker United Metallurgical Company OMK is implementing a project to install two robotic mills for rolling spring sheets at its plant in Chusovoy in Perm Territory, which is the country's leading manufacturer of automotive components for domestic trucks and foreign cars. The volume of investments is about 650 million rubles. The new equipment will allow OMK to more than double its capacity for the production of leaf springs for parabolic (low-leaf) springs, which have more complex geometry and stricter quality tolerances.

 

New mills are installed in addition to the three existing ones. The first mill from Bredtmann-Girke in Germany, equipped with five Japanese Fanuc robots, has already been put into operation. Thus, a unique straightening machine included in the complex adjusts the operation algorithm for each specific spring sheet, determining deviations from the geometry, and the rolling quality is controlled on a measuring machine using a laser.

 

A second mill with similar characteristics is planned to be commissioned in the second half of 2022. It will be additionally equipped with a curling machine for curling spring strips, which will ensure a continuous technological cycle, reduce the production time of springs and increase the range of products.

 

At the beginning of 2020, OMK announced technical re-equipment rolling production at the Chusovoy plant to provide spring lines with the highest quality rolled products for the production of both those already in demand on the market and new types of products. As part of the project, the enterprise is installing a modern section rolling mill with a capacity of more than 200 thousand tons of rolled metal per year from Danieli, as well as a water treatment section and a roll mill. The first products at the new mill are planned to be released in 2022.
