Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for reforming casting vessels and other plastically deformable objects like pipes and tanks are costly and time-consuming, requiring hot reforming processes that result in significant production downtime.
Innovation Solution
A device comprising a central shaft, central gear, roller gears, and rollers with specific shapes and surfaces, along with a translation member and idler member, is used to progressively reform vessel cavities by rotating and moving through the cavity, allowing for efficient deformation of internal walls without the need for extensive heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hot reforming process is used to reform casting vessels, then the vessel cavity can be deformed, but the production downtime is significant (up to twelve hours) and the process is costly
Solution Approach 1:
The patent replaces the traditional thermal-mechanical reforming system with a purely mechanical roller-based system. Instead of using heat and hydraulic presses to slowly push cylinder walls out, the invention uses rotating rollers with specific surface geometries to mechanically deform the vessel cavity through controlled contact and rotation, dramatically reducing reforming time from twelve hours to minutes
Solution Approach 2:
The reforming device is segmented into multiple independent rollers that can be individually configured with different surface geometries (helical ridges, concentric grooves, smooth surfaces). These segmented rollers work in sequence or parallel to progressively deform different regions of the vessel cavity, enabling precise control over the deformation process while maintaining high speed
2Manufacturing precision
If hot reforming process is used to reform casting vessels, then the vessel cavity can be deformed, but the process is costly and energy-consuming
Solution Approach 1:
The invention eliminates the thermal energy input required by traditional hot reforming processes by substituting it with mechanical energy from rotating rollers. The mechanical system uses controlled friction and contact pressure between the rollers and vessel wall to achieve deformation without heating, significantly reducing energy consumption and eliminating associated costs
Solution Approach 2:
The reforming process transitions from static hydraulic pressing to dynamic roller rotation. The rotating rollers continuously engage and disengage with the vessel cavity, creating dynamic deformation forces that are more efficient than static pressure application. The rotational motion allows for continuous reforming action rather than intermittent pressing cycles
