AI Technical Summary
The existing guide device for steel section rolling mills cannot achieve synchronous and symmetrical adjustment of the guide rollers, resulting in unstable guidance of steel section rolls, inconvenient operation, and inability to meet multiple guidance requirements.
The design employs a combination of a base, a synchronous adjustment component, a first guide component, a second guide component, and a lifting adjustment component. The synchronous adjustment and lifting of the guide wheels are achieved through a servo motor and an electric push rod, ensuring the stability of the guide component and its multiple guiding capabilities.
It enables convenient and synchronous adjustment of the guide wheel spacing, improves the guiding stability and adaptability of steel rolls, and is suitable for guiding requirements of different steel rolls.
