Rolling Mill Axial Displacement Block for Compact Cylinder Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional axial displacement devices in rolling devices have high raw material and production costs due to their one-piece design, require extensive space for displacement cylinders, and are cumbersome to maintain and repair, with integrated shifting cylinders necessitating complex hose connections and disassembly.
Innovation Solution
A rolling device with a multi-part fixed block design, where the central sliding bracket is forged and the outer holding strips are made from sheet metal, allowing for standard components and external displacement cylinders, reducing costs and space while enhancing maintenance and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a one-piece fixed block is used in the axial displacement device, then structural strength and rigidity are ensured, but raw material costs and production costs increase significantly
Solution Approach 1:
The fixed block is divided into multiple separate components: a central guide web component and two retaining strip components. These components are manufactured separately and assembled together using connecting elements, replacing the expensive one-piece forging while maintaining structural integrity and load-bearing capacity.
2Device complexity
If displacement cylinders are integrated within the bending blocks, then compact design is achieved, but maintenance and repair become cumbersome requiring complete disassembly
Solution Approach 1:
The displacement cylinders are extracted from the bending blocks and repositioned in the available space between the fixed block components. This external positioning allows the cylinders to be accessed, maintained, and repaired independently without requiring disassembly of the bending blocks or complete removal of the axial displacement system.
3Device complexity
If displacement cylinders are integrated within the bending blocks, then the design is compact, but significant installation space is required due to cylinder stroke length
Solution Approach 1:
The displacement cylinders are arranged in the lateral dimension between the guide web and retaining strips rather than within the bending blocks. This spatial reconfiguration utilizes previously underutilized space, reducing the axial length requirement while maintaining the necessary stroke length for roll gap adjustment.
4Stability of the object's composition
If a one-piece fixed block is used, then structural integrity is maintained, but assembly complexity and time increase
Solution Approach 1:
The fixed block is segmented into standardized components that can be manufactured independently using simpler processes and assembled through standardized connecting elements. This modular approach reduces manufacturing complexity and assembly time while maintaining the structural integrity needed to support the rolling mill operations.

Implementation Method 1
The axial displacement device has a fixed block, at least one displaceable bending block and at least one displacement cylinder associated with the bending block, with which the bending block can be displaced relative to the fixed block
