Straightening Roll Replacement Using a Movable Shaft Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straightening apparatuses for metal products are complex and time-consuming to operate, often requiring bulky and costly support structures, and result in roll oxidation and scale buildup during replacement.
Innovation Solution
A straightening apparatus with selectively removable straightening rolls, utilizing a movement member and gripping means to simplify roll replacement, eliminating the need for complex support structures and reducing operational time, while preventing oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a mobile store with holding members is used to support straightening rolls during replacement, then the rolls can be positioned in advance, but the operation becomes extremely complex and the mobile store gets completely dirtied by oxidation and scale
Solution Approach 1:
The invention extracts the straightening roll from the complex mobile store system and positions it directly on the rotation shaft using a simple pushing motion. The roll is taken out of the complicated support structure and placed directly where needed, eliminating the need for complex holding members and mobile stores.
Solution Approach 2:
Instead of moving the mobile store toward the fixed shoulder to install rolls, the invention inverts the approach by having the roll itself move along the rotation shaft toward its mounting position. The push member applies force from the opposite direction, pushing the roll into place rather than pulling it through complex mechanisms.
2Object-affected harmful factors
If bridge cranes and mobile support frames are used to transport straightening rolls, then the support frames do not get dirtied, but the structure becomes complex and bulky requiring high installation height
Solution Approach 1:
The invention extracts the roll transport function from the complex bridge crane and mobile support frame system. By using a simple push member that moves along the rotation shaft, the roll is transported and installed without needing bulky support frames or high-crane operations, eliminating the harmful oxidation exposure while simplifying the structure.
Solution Approach 2:
The rotation shaft itself serves as the transport path for the straightening roll. The roll moves along the shaft under its own guidance, eliminating the need for external bridge cranes and mobile support frames. The system uses its own structural elements (the rotation shaft) to perform the transport function.
3Reliability
If multiple straightening rolls are installed on rotation shafts with fixed and mobile shoulders, then the apparatus can perform straightening operations, but roll replacement becomes time-consuming and operationally complex
Solution Approach 1:
The invention replaces the complex mechanical system of mobile shoulders, holding members, and coordinated movements with a simple linear push member that applies direct mechanical force along the rotation shaft. This substitution of the mechanical replacement system with a simpler pushing mechanism dramatically reduces operational complexity and increases replacement speed while maintaining straightening capability.

AI summary
Apparatus for straightening metal products comprising:at least one rotation shaft on which at least one straightening roll is installed in a selectively removable manner;a first structure provided with at least a first support member configured to hold and support a first end of the rotation shaft;a second structure provided with at least a second support member configured to selectively support and hold a second end, opposite the first end, of the rotation shaft;a movement member configured to move the second structure toward/away from the first structure and to allow the installation or removal of the straightening roll from the rotation shaft.
