Wheel Rim Roller Finishing for Inner Flange Roundness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The machining process for aluminum wheel rims often results in deformation and low roundness, particularly near the inner flange, leading to issues with eccentricity and machining failures, which increases material waste and production costs.
Innovation Solution
A wheel rim finishing device comprising a stand, motor, shaft sleeve, and rollers that improve the roundness of the blank rim through a combination of a rotating component with a locating disk, supporting body, and roller structures, allowing for precise finishing before machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the blank rim is thickened to avoid machining failures, then the machining quality and finished product ratio improve, but the aluminum alloy raw material is wasted and manufacturing cost increases
Solution Approach 1:
The patent applies preliminary action by performing rim finishing before machining operations. The finishing device corrects rim deformation and improves roundness in advance, ensuring that subsequent machining operations can proceed without failures. This eliminates the need to thicken the rim as a preventive measure, thereby avoiding material waste while maintaining high machining quality and finished product ratio
2Device complexity
If conventional machining processes are used directly on cast rims, then the production process is simple, but the rims exhibit deformation and low roundness particularly near the inner flange
Solution Approach 1:
The patent introduces a preliminary finishing operation before conventional machining. The finishing device includes rollers that apply controlled pressure to the rim surface, correcting deformation and improving roundness. This preliminary action addresses the roundness issue without significantly complicating the overall production process, as the finishing operation can be integrated into the existing workflow
3Manufacturing precision
If the blank rim roundness is improved through finishing, then the machining volume is reduced and manufacturing cost decreases, but additional finishing equipment and processes are required
Solution Approach 1:
The finishing device is segmented into independent functional modules: a locating disk for positioning, adjustable rollers for applying pressure, and a driving mechanism. This segmentation allows the equipment to be compact and adaptable to different rim types. The modular design reduces overall device complexity while achieving the desired roundness improvement and machining volume reduction
