 Forming and rolling irregular ring forgings on a horizontal CNC ring rolling mill

The main roll has the ability to work in two positions and is equipped with mechanical or hydraulic locking mechanisms. It provides single-pass rolling and forming of workpieces with internal holes of complex configuration; Switching between positions is carried out automatically, without the need to stop the machine or manual adjustment.

The main roller assembly can be moved axially by hydraulic cylinders, allowing rolling operations to be carried out in two working positions. When processing parts with a complex external profile, the process begins with simultaneous radial and axial rolling aimed at expanding the internal hole; after reaching the specified expansion coefficient, the external profile is formed. This approach makes it possible to carry out a full cycle of rolling and forming complex parts within one heating cycle, while the transition between working positions is performed automatically - without the need to stop the machine or manual readjustment.

The functions of the two-position support roller and two-position main roller work in harmony, providing flexible adjustment of the support roller length depending on the height of the workpiece, which can significantly extend its service life.
