(CNC Upper Roller Universal Three-Roll Rolling Machine):
Product Features:
1. This state-of-the-art hydraulic three-roll rolling machine is specifically designed to shape steel plates into cylindrical, conical, and precisely corrected circular forms with unmatched precision.
2. The upper roller is engineered to move both vertically and horizontally, offering versatile positioning for various rolling needs.
3. During the pre-rolling phase, the upper roller achieves asymmetrical positioning relative to the lower roller through horizontal movement, ensuring impeccable pre-rolling precision.
4. For conical rolling, the upper roll tilts at both ends, flawlessly shaping the cone to perfection.
5. In the circular correction process, the upper roll is centrally positioned to press and roll the stress zone of the cylinder, efficiently eliminating welding stress and enhancing the roundness of the cylinder.
6. During the rolling process, the lower rolls are powered by an electric motor and gearbox, delivering the necessary torque to achieve seamless rolling of the cylinder.
7. Key technical parameters: (For a steel plate with a yield strength of 245Mpa, thicknesses of 30/100/150mm, and a width of 3000mm as an example).
