Hexagonal Rolling Stand Housing for Switchable Roller Guide Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling stands for metal rods, wires, or pipes require significant effort to modify the roller guide arrangement and adjustment configuration when switching between Y-arrangement and anti-Y-arrangement, especially when manual and automatic adjustment is involved, and are limited by a fixed design that restricts flexibility and position selection in a rolling mill.
Innovation Solution
A stand with a hexagonal housing design featuring eccentric bushings for adjustable roller spacing and a universal shaft for central adjustment, allowing for flexible positioning and configuration changes, including both manual and automatic adjustment options, while maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If roller guides are attached to the inlet side of a stand to control material feeding and prevent torsional movement, then the reliability of the rolling process is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The stand housing is designed with a regular hexagon cross-section that serves multiple functions: it provides the structural framework, defines the inlet and outlet sides, and incorporates mounting positions for roller guides and adjustment mechanisms. This universal design allows the same hexagonal housing to support both Y-arrangement and anti-Y-arrangement configurations without requiring separate structural components, thereby improving reliability while controlling complexity.
Solution Approach 2:
The roller guide incorporates a dynamic adjustment mechanism with a universal shaft that can be repositioned along the hexagonal housing. This dynamic capability allows the roller guide to adapt its position and orientation based on whether the stand is configured for Y-arrangement or anti-Y-arrangement, ensuring reliable material feeding control while using a single versatile mechanism rather than multiple fixed structures.
2Ease of manufacture
If stands are designed with fixed Y-arrangement or anti-Y-arrangement configurations to simplify individual stand design, then the ease of manufacture is improved, but the adaptability decreases when switching between arrangements is required
Solution Approach 1:
The hexagonal stand housing provides six identical sides that can serve as inlet or outlet sides depending on the desired arrangement. The roller guide and adjustment mechanisms are designed to be repositionable within this universal hexagonal framework, allowing the same manufactured stand to be configured for both Y-arrangement and anti-Y-arrangement by simply repositioning components rather than manufacturing different stands.
Solution Approach 2:
The stand is segmented into modular components: the hexagonal housing structure, the roller guide assembly, and the adjustment mechanism. This segmentation allows individual components to be manufactured separately with standardized interfaces, then assembled and reconfigured for different arrangements. The roller guide can be detached and repositioned to different sides of the hexagon, enabling arrangement switching while maintaining ease of manufacture through standardized parts.
3Adaptability or versatility
If multiple specialized stands are used to cover different positions and configurations in a rolling mill, then the adaptability is improved, but the device complexity and cost increase
Solution Approach 1:
The hexagonal stand housing with repositionable roller guide and adjustment mechanisms creates a universal stand that can function in multiple positions and configurations within a rolling mill. The same stand can be rotated or reconfigured to serve as a Y-arrangement stand, anti-Y-arrangement stand, or positioned at different locations in the rolling sequence, eliminating the need for multiple specialized stands and reducing overall system complexity.
Solution Approach 2:
The dynamic repositioning capability of the roller guide along the hexagonal housing allows a single stand to adapt to different operational requirements. The universal shaft mechanism enables the roller guide to be moved to different sides of the hexagon and reoriented, providing the flexibility of multiple specialized stands while using only one physical unit, thereby reducing device complexity while maintaining adaptability.

AI summary
The present application relates to a stand (1) for rolling metal rods, wires, or pipes, along a rolling axis (19). The stand (1) comprises three rollers (20.1, 20.2, 20.3) which are located on one roller shaft in each case and surround the rolling axis (19) in a star-shaped manner, and which together form a caliber (21), a stand housing (10) having an outside (12) which, viewed along the rolling axis (19), comprises at least six side surfaces (14.1, 14.2, 14.3, 14.4, 14.5, 14.6) that are arranged so as to be offset about the rolling axis (19), about a 60° rotation in each case, and two end faces (13, 15) which are opposite one another, wherein the side surfaces (14.1-14.6) form a regular hexagon, at least in an imagine extension, and a roller guide (60) which is attached to one of the end faces (13, 15) of the stand housing (10) and comprises a universal shaft (62), wherein the universal shaft (62) comprises a roller adjustment connector (64) via which a central adjustment of the roller guide (60) is possible and which is attached on the stand housing (10) in one corner (16.1, 16.2, 16.3, 16.4, 16.5, 16.6) of the hexagon.
