Rolling Stand Housing Support Surfaces for Flexible Rail Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling stands for metal bars, wires, or tubes have limitations in adjusting roll positions, leading to insufficient roundness of the rolled material and difficulty in automated adjustment due to obstructed access for manual operation.
Innovation Solution
A stand housing with four support surfaces arranged at 120° angles, allowing modular and flexible positioning and adjustment configurations, including manual and remote operation options, while maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adjustment connection is provided on one side face of the stand housing, then manual operation is easily accessible, but automated operation becomes difficult due to obstruction by motors and drive components
Solution Approach 1:
The side face of the stand housing is designed with a universal adjustment connection interface that can accommodate both manual operation and automated motor-driven operation. The coupling mechanism is configured to receive either a manual operating tool or an automated coupling device, allowing the same physical interface to serve dual purposes without requiring separate adjustment mechanisms.
2Manufacturing precision
If multiple rolling stands are arranged sequentially to improve roundness, then the cross-section becomes more circular, but the space requirements and device complexity increase
Solution Approach 1:
The rolling stands are configured with asymmetric roll arrangements (Y-arrangement and anti-Y-arrangement) where the rolls are positioned at different angular orientations around the rolling axis. This asymmetric configuration allows each stand to contribute differently to the rounding process, achieving improved roundness through the cumulative effect of corner rounding while potentially reducing the number of stands needed compared to symmetric arrangements.
3Adaptability or versatility
If the stand housing design allows flexible positioning for different arrangements, then adaptability increases, but the structural complexity of the support surfaces increases
Solution Approach 1:
The stand housing incorporates universal support surfaces with standardized bearing surfaces that can accommodate multiple positioning configurations. These support surfaces are designed with consistent geometric features that allow the stand housing to be positioned in different orientations (Y-arrangement and anti-Y-arrangement) while maintaining the same interface with the stand mount, thereby providing positioning flexibility without increasing structural complexity.

AI summary
The present application relates to a stand housing (10) for a rolling mill stand (1) for rolling metallic bars, wires, or tubes along a rolling axis (19), which has at least four support surfaces arranged on an outer surface (12) of the stand housing (10) that are parallel to the rolling axis (19) when viewed along it. Of the support surfaces, two are non-adjacent and parallel to each other, and the other two are adjacent. The adjacent support surfaces are at a 120° angle to each other, and each of them is at a 120° angle to one of the parallel support surfaces. The two parallel support surfaces and/or the adjacent support surfaces are designed to receive sliding rails (40.2, 40.3, 40.4, 40.5) for inserting the stand housing (10) into a stand receptacle.
