Multi-roll bending machine

Multi-roll bending machine with support rolls, pressure rolls, and an auxiliary frame with curvature grooves

This technology relates to a multi-roll bending machine in which support rolls and pressure rolls are arranged on a main frame consisting of side frames and a base frame, with the pressure rolls secured by an auxiliary frame featuring curvature grooves.

Conventional roll bending machines have suffered from issues with bending precision and repeatability due to insufficient structural rigidity in securing the pressure rolls.

To address this, our technology utilizes an auxiliary frame with a first groove featuring a curvature radius that corresponds to the pressure roll radius, firmly securing the top of the pressure roll to achieve stable and precise bending.

Key Features:

• A main frame comprising first and second side frames spaced apart from each other, with a base frame fixed to both ends.
• A support roll with both ends rotatably coupled to the upper side of the base frame.
• A pressure roll with both ends rotatably coupled to the upper side of the support roll.
• An auxiliary frame coupled to the top surface of the base frame to secure the upper part of the pressure roll, featuring a first groove with a curvature radius corresponding to the radius of the pressure roll.
