Multipart Roll Axial Displacement Structure for Compact Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional axial displacing devices in rolling apparatuses have high raw material and assembly costs due to complex, one-part designs, occupy large installation space, and are difficult to maintain and repair, with integrated displacing cylinders requiring hose fittings and extensive disassembly.
Innovation Solution
A multipart axial displacing device with a central displacing bracket and separate retention bars, where displacing cylinders are externally mounted, allowing for modular construction and reduced component costs, improved maintenance, and a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a one-part fixed block is used in the axial displacing device, then structural integrity is improved, but manufacturing complexity and raw material costs increase
Solution Approach 1:
The fixed block is divided into multiple separate parts: a central guide web component and two retention bar components. These parts are manufactured separately and then assembled together using fastening means, reducing manufacturing complexity and raw material costs while maintaining the structural integrity needed for guiding the bending blocks axially.
2Shape
If displacing cylinders are integrated inside the bending blocks, then structural compactness is improved, but installation space and maintenance difficulty increase
Solution Approach 1:
The displacing cylinders are extracted from the bending blocks and mounted externally on the fixed block. This allows the bending blocks to be smaller and more compact, while the displacing cylinders become independently accessible for maintenance and repair without requiring removal of the bending blocks or extensive disassembly of the axial displacing device.
3Stability of the object's composition
If displacing cylinders are integrated inside the bending blocks, then structural unity is improved, but installation space requirement increases
Solution Approach 1:
The axial displacing device is segmented into distinct functional components: the fixed block with externally mounted displacing cylinders, and the bending blocks that are separate from the cylinders. This segmentation allows the bending blocks to be more compact since they don't need to accommodate the cylinder volume, reducing the overall installation space requirement while maintaining structural unity through proper assembly.
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
The multipart design reduces raw material and assembly costs, facilitates maintenance, and provides a more compact and accessible structure, enabling easier installation and replacement of components without the need for hose fittings.
Implementation Method 1
The displacing device has a fixed block, at least one displaceable bending block, and at least one displacing cylinder, using which the bending block can be displaced relative to the fixed block
