Adjustable Straightening Rollers for Steel Profile Chamber Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guidelines with double-stored directional waves face challenges in adjusting chamber measurements or the distance between individual rollers, particularly when trying to match the tolerance of built-up profiles, which can necessitate complex reinstallation of directional rollers.
Innovation Solution
The guideline features a double-mounted directional wave system with axially adjustable rollers, where an adjustment nut is used to shift the storage base by twisting the wave of directions, allowing for precise adjustment of the chamber size and roller distance through a main drive and incremental provider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If double-bearing straightening shafts are used with fixed roller spacing, then structural stability is improved, but adjustment of chamber dimension becomes difficult and complex
Solution Approach 1:
The patent applies the dynamics principle by making the bearing bush axially displaceable along the straightening shaft. The bearing bush can be positioned at different axial locations to adjust the chamber dimension, while the straightening shaft itself remains structurally stable with double-bearing support. This dynamic positioning capability allows easy adjustment without compromising structural stability.
2Ease of operation
If axially displaceable bearing bush with adjusting nut is used, then ease of adjustment is improved, but rotational stability during adjustment may worsen
Solution Approach 1:
The adjusting nut serves as an intermediary mechanism between the rotational adjustment action and the axial displacement of the bearing bush. By engaging the adjusting nut with threaded engagement, the system converts rotational motion into controlled axial displacement, providing both ease of adjustment and rotational stability through the self-locking nature of threaded connections.
3Manufacturing precision
If precise adjustment mechanism is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The adjusting nut mechanism is designed to be self-contained and self-servicing. The threaded engagement provides inherent precision through the thread pitch, and the mechanism is self-locking, eliminating the need for additional locking devices or complex control systems. The bearing bush automatically maintains its position once adjusted, providing precision without excessive complexity.
