Segmented Vortex Tool for Flying Saw Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flying saws with internal toothed saw blades face challenges in unscheduled tool changes, as the closed ring tool cannot be easily removed without first separating the pipe.
Innovation Solution
A vortex separating device with a whirling tool designed from multiple ring segments, featuring an arcuate groove and web positioning system, allowing for partial segment removal and automatic assembly, enabling tool changes without prior pipe separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a closed ring tool with internal toothing is used for whirling cutting, then cutting efficiency and productivity are improved, but tool removal and replacement become difficult without prior pipe separation
Solution Approach 1:
The closed ring tool is divided into multiple individual segments that can be removed and replaced independently. Each segment is a separate component that fits into the tool holder, allowing partial removal of only the worn or damaged segments while leaving the remaining segments in place. This segmentation enables tool replacement without requiring complete disassembly or prior pipe separation, thus resolving the contradiction between maintaining cutting efficiency and enabling easy tool removal.
2Adaptability or versatility
If multiple ring segments are assembled to form a closed tool, then tool flexibility and replaceability are improved, but positioning precision and assembly reliability become challenging
Solution Approach 1:
The tool holder and ring segments incorporate asymmetric positioning features including arcuate grooves and corresponding arcuate webs. These asymmetric geometric forms provide unique orientation and location for each segment, ensuring precise positioning when assembled. The asymmetric design prevents incorrect assembly and maintains consistent cutting geometry, thereby achieving both tool flexibility through segment replacement and positioning precision through the specialized geometric interfaces.

AI summary
The invention relates to a vortex cutting device for use in flying saws, comprising a tool holder and an annular vortex tool held therein. The annular vortex tool (1) is formed from at least two ring segments (2), which are provided with a positioning device on their side facing the tool holder. The tool holder corresponds to a positioning device arranged on the tool holder, thereby achieving a centered arrangement of the ring segments (2) relative to each other and a centering of the vortex tool (1) in the tool holder. The invention further relates to an annular vortex tool for use in a vortex cutting device for use in flying saws.The ring-shaped vortex tool is formed from at least two ring segments (2), each of which has a positioning device on at least one side in the form of an arc-shaped circular segment-like groove (3) or an arc-shaped circular segment-like web.
