Rolling Stand Work Roll Chock Guide with Parallel Antifriction Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices for work roll chocks in rolling stands experience significant friction, which complicates the guidance of bending blocks and hinders efficient operation.
Innovation Solution
A guide device with two parallel guides per side, where each bending block uses only one guide with antifriction bushings, reducing friction by allowing one guide to enclose the other, and incorporating slide plates to prevent twisting, with the guides being round and attached via brackets, and optionally featuring a horizontal shift system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional guide devices with multiple guides per bending block are used, then guidance stability is improved, but friction increases significantly
Solution Approach 1:
The patent extracts only the necessary guidance function by using a single guide per bending block instead of multiple guides, removing redundant contact points that generate friction while maintaining adequate guidance stability through the strategic placement and design of the remaining guide
Solution Approach 2:
The patent introduces an intermediary element (the opening in one guide that encloses the other guide) that allows the bending block to be guided by only one active guide at a time, reducing friction while the nested guide structure provides stability when needed
2Loss of energy
If antifriction bushings are used in guides, then friction is reduced, but device complexity increases
Solution Approach 1:
The patent applies antifriction bushings locally only at the specific contact points where bending blocks interact with guides, rather than throughout the entire system, reducing friction where needed while minimizing the addition of complex components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces friction in the system, allowing for smoother guidance of bending blocks and preventing twisting, while maintaining the advantages of rapid roll replacement and compatibility with conventional designs and mechanisms.
Implementation Method 1
each bending block comprises only one tube, which holds two antifriction bushings
Implementation Method 2
Slide plates can be provided on the front side of the rear bracket to prevent twisting

AI summary
A guiding device for the chocks of work rolls of a rolling stand comprising guides arranged fixedly or horizontally movably on the inner sides of the windows of the rolling stand, wherein the upper and lower bending blocks of each side are respectively assigned two guides arranged parallel to each other. Each bending block is assigned one of the guides, while it has a recess for the parallel running guide that extends around said guide, wherein the upper bending block is guided on one of the parallel guides and the lower bending block is guided on the other guide.
