Modular Rolling Mill Stand Base for Flexible Layout and Force Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling mills are inflexible and cannot be adjusted to different requirements regarding the number and arrangement of stands, leading to inaccurate force measurements and reduced stability due to direct force transmission and interference from external forces.
Innovation Solution
A modular stand base design with receiving modules fastened to a common lower and upper frame, allowing flexible arrangement and secure reception of individual stands, incorporating force measurement and protection features to enhance stability and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rolling mill is designed with a fixed number of stands arranged one behind the other, then the structure is simple and stable, but it cannot be flexibly adjusted to different requirements regarding the number and arrangement of stands
Solution Approach 1:
The stand base is divided into multiple receiving modules, each capable of independently receiving a stand. These modules can be arranged in different configurations along the rolling direction, allowing flexible adjustment of the number and arrangement of stands without redesigning the entire base structure
Solution Approach 2:
Each receiving module is designed with universal functionality to accommodate different stand types and configurations. The modules can be used in various combinations and arrangements, making the rolling mill adaptable to different production requirements while maintaining a standardized base structure
2Stability of the object's composition
If stands are directly fastened to a common base frame, then the structure is simple, but forces acting on the stands are transmitted directly into the base, reducing stability and measurement precision
Solution Approach 1:
A common upper cover frame is introduced as an intermediary structure between the stands and the lower base frame. This cover frame absorbs forces acting on the stands during operation, preventing direct force transmission into the base and improving both stability and measurement precision while maintaining structural simplicity
3Measurement precision
If a common stand clamping system is used for all stands, then the structure is simple and stable, but the clamping interferes with measuring signals, falsifying force measurements
Solution Approach 1:
The clamping system is segmented and integrated into individual receiving modules rather than using a common clamping mechanism. This allows force measurements to be taken at the module level, isolating measurement points from clamping interference and enabling accurate force measurements while maintaining structural simplicity
