Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for correcting roundness deformations in aluminum alloy wheels during heat treatment are inefficient, labor-intensive, and ineffective for both depressions and bulges, as they rely on manual handling and hydraulic force without precise control.
Innovation Solution
An improved inner-supporting-type online roundness correcting device that uses a machine frame with gears, hydraulic cylinders, servo motors, and V-type rollers to automatically clamp and adjust the wheel, allowing precise correction of roundness and cylindricity through synchronized hydraulic and motorized mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual handling and hydraulic force are used for roundness correction, then the device complexity is reduced, but the manufacturing precision and automation level deteriorate
Solution Approach 1:
The correcting device is divided into multiple independent correcting wheels (I and II) on both left and right sides, each capable of independent adjustment. This segmentation allows precise localized correction of different deformation areas while maintaining overall system manageability
Solution Approach 2:
The patent employs servo motors and hydraulic cylinders to create dynamically adjustable correcting mechanisms. The correcting wheels can be precisely positioned and adjusted in real-time based on detected deformation, enabling high-precision automated correction without overly complex fixed structures
2Ease of operation
If manual handling and approximate repair by experience are used, then the ease of operation is improved, but the productivity and automation level deteriorate
Solution Approach 1:
The system incorporates roundness detection capabilities that provide feedback on wheel deformation. This feedback guides the correcting wheels to apply force precisely where needed, eliminating the need for operator experience while maintaining ease of operation through automated control
Solution Approach 2:
The correcting device automatically identifies and corrects deformations without requiring manual intervention or operator judgment. The system serves itself by detecting its own correction needs and executing the correction process, significantly improving productivity while keeping the operation simple
3Force
If internal supporting with hydraulic cylinders is used, then the force application capability is improved, but the adaptability to different deformation types deteriorates
Solution Approach 1:
The hydraulic force application is segmented into multiple correcting wheels (I and II) that can independently target different deformation types. This allows the system to maintain strong force application capability while adapting to various deformation patterns including both depressions and bulges
Solution Approach 2:
The correcting wheels are designed with dynamic positioning and force adjustment capabilities through servo motors and hydraulic control. This enables the system to adapt its force application to different deformation types and locations, making it versatile while maintaining adequate correcting force

AI summary
The present invention provides an improved inner-supporting-type online roundness correcting device for a semifinished wheel, which comprises a machine frame, hydraulic cylinders, guide rails, servo motors and correcting wheels. When a bulge of the wheel is met, angles of left correcting wheels II are adjusted through a left servo motor, the left correcting wheels II are kept to be in contact with an inner rim of the wheel all the time and remain stationary in the position, and then, a left hydraulic cylinder enables a left correcting wheel Ito press the bulge of the wheel, so as to recover the roundness of the bulge; and when a depression of the wheel is met, right correcting wheels I are kept to be in contact with an outer rim of the wheel all the time and remain stationary in the position through a right hydraulic cylinder, the angle of a right correcting wheel II is adjusted through a right servo motor, and compressing hydraulic cylinders enable the right correcting wheel II to press the depression of the wheel, so as to recover the roundness of the depression.
