Modular Rolling Mill Stand Base for Flexible Stand Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling mills are inflexible in adjusting the number and arrangement of stands, leading to falsified measuring signals due to common stand clamping and inability to handle varying requirements effectively.
Innovation Solution
A modular stand base with individually mountable receiving modules, each designed to receive multiple side surfaces of a stand, equipped with protective flaps and force measurement capabilities, allowing flexible arrangement and precise control of stands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rolling mill is designed with a fixed number of stands arranged in pairs, then the structure is simple and stable, but the rolling mill cannot be flexibly adjusted to different requirements
Solution Approach 1:
The stand base is divided into multiple receiving modules, each capable of independently receiving a stand. This segmentation allows the rolling mill to be configured with different numbers and arrangements of stands by simply assembling or disassembling individual modules, thereby achieving flexibility without excessive structural complexity.
Solution Approach 2:
Each receiving module is designed with a universal structure that can accommodate different stand configurations. The modules can be arranged in various sequences and combinations to meet different rolling requirements, making the stand base multi-functional and adaptable to diverse production needs.
2Measurement precision
If common stand clamping is used to secure multiple stands, then the structure is simple, but the measuring signals are falsified
Solution Approach 1:
The clamping structure is segmented into individual clamping units, each associated with a specific receiving module and stand. This allows force measurement to be performed independently for each stand, eliminating the interference caused by common clamping and enabling accurate measurement of individual stand forces.
Solution Approach 2:
Force measurement devices are introduced as intermediaries between the stands and the receiving modules. These devices accurately transmit and measure the forces acting on each stand without the falsifying effect of common clamping, enabling precise measurement while maintaining structural integrity.
3Adaptability or versatility
If stands are arranged in fixed pairs with alternating Y and anti-Y arrangements, then the rolling process is stable, but the rolling mill cannot handle varying production requirements
Solution Approach 1:
The stand base is segmented into independent receiving modules that can be easily assembled, disassembled, and reconfigured. This segmentation enables quick exchange of stands for maintenance or replacement and allows flexible rearrangement to handle varying production requirements, improving both adaptability and ease of operation.
Solution Approach 2:
The stand base structure is made dynamic through the use of detachable and reconfigurable receiving modules. Instead of a fixed arrangement, the modules can be dynamically reconfigured to accommodate different stand numbers, types, and arrangements, enabling the rolling mill to adapt to varying production demands while maintaining operational simplicity.
