Vertical Roll Stand Guide With Offset Tracking for Rolled Stock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolled material guiding systems require manual adjustment and have limited ability to absorb tilting torques, with guide plates only forming lateral guidance and being prone to undesired engagement during rolling processes.
Innovation Solution
An intermediate stand guide on a vertical roll stand with adjustable guide elements that follow the adjustment movement of the vertical roll, allowing for precise offset positioning outside the machine, using compensation plates and overload safeguards to manage torques and prevent undesired engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If guide plates are used for lateral guidance of rolled material, then guiding function is provided, but tilting torques can only be absorbed to a restricted extent
Solution Approach 1:
The guide structure is segmented into multiple guide elements (first and second guide elements) positioned at different locations. Each guide element independently engages with the rolled material, distributing the torque absorption across multiple contact points rather than relying on a single rigid guide plate, thereby increasing overall torque absorption capability while maintaining structural simplicity.
Solution Approach 2:
The guide elements are arranged in different transverse positions relative to the rolled material width. The first guide element is positioned at a first offset dimension and the second guide element at a second offset dimension, creating a multi-dimensional guidance system that can absorb tilting torques through spatial distribution rather than just lateral guidance.
2Measurement precision
If guide element is positioned close to vertical roll for accurate guidance, then guiding precision is improved, but undesired engagement during edging rolling occurs
Solution Approach 1:
Different guide elements are positioned at different offset dimensions from the vertical roll, creating localized guidance zones. The first guide element operates at a first offset dimension for normal guiding, while the second guide element at a second offset dimension provides backup or alternative engagement, allowing each element to have optimized local positioning that avoids undesired engagement while maintaining guiding precision.
Solution Approach 2:
The guide elements are pre-positioned at specific offset dimensions during installation to prevent undesired engagement before the rolling process begins. The offset dimensions are calculated and set in advance based on the rolled material dimensions and roll geometry, ensuring that the guide elements are already in the correct positions to provide accurate guidance without interference during the edging rolling process.
3Adaptability or versatility
If manual adjustment of guide plates is used, then adjustment flexibility is provided, but personnel deployment in machine is required
Solution Approach 1:
The guide elements are designed to automatically adjust their positions based on the rolled material width and roll position. The guide elements follow the adjustment movement of the vertical roll, meaning that when the roll position changes, the guide elements automatically reposition themselves through mechanical coupling, eliminating the need for manual adjustment while maintaining adaptability to different rolling conditions.
Solution Approach 2:
The guide elements are mechanically coupled to the vertical roll adjustment mechanism, creating a feedback system where the roll position directly influences the guide element position. As the vertical roll adjusts to different positions, the guide elements receive feedback through the mechanical connection and automatically move to the appropriate positions, providing continuous adaptation without manual intervention.
