Conical Hollow Deburring Tool with Segmented Flutes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring tools are inefficient in uniformly and rapidly removing burrs from the outer circumferential edges of pipes or bar stocks caused by cutting, as they often require multiple passes and may not effectively address both interior and exterior burrs.
Innovation Solution
A deburring tool with a conical hollow body featuring multiple flutes and recessed cutouts, equipped with primary and secondary cutting edges, and a detachable shaft portion for engagement with a driving tool, allowing for efficient removal of burrs through rotational motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional deburring tool with simple conical surface is used, then the tool structure is simple, but the deburring efficiency and uniformity are insufficient
Solution Approach 1:
The conical hollow body is segmented into multiple flutes (at least three) extending along the conical surface, with each flute containing cutting edges. This segmentation allows simultaneous engagement with different portions of the pipe end, enabling rapid and uniform removal of both interior and exterior burrs while maintaining a relatively simple overall tool structure
Solution Approach 2:
The tool applies different cutting edge configurations to different local areas: the first cutting edge removes interior burrs while the second cutting edge removes exterior burrs. The flutes are strategically positioned and angled to provide optimal cutting action at specific locations, achieving superior deburring performance without requiring complete structural redesign
2Productivity
If a single cutting edge is used, then the tool structure is simple, but the ability to remove both interior and exterior burrs effectively is limited
Solution Approach 1:
The tool merges multiple cutting functions into a single integrated conical hollow body structure. Both interior and exterior cutting edges are combined on the same tool body, allowing simultaneous deburring of both pipe end surfaces during one operation, thereby achieving uniform deburring results without requiring multiple separate tools or passes
3Productivity
If the flutes are arranged without inclination, then the tool structure is simpler, but the cutting ability and burr removal effectiveness are reduced
Solution Approach 1:
The flutes are arranged with specific inclination angles relative to the conical surface, creating an asymmetric configuration optimized for cutting action. This asymmetric flute arrangement enhances the tool's cutting ability by directing chip flow and applying cutting forces more effectively, resulting in improved burr removal performance while maintaining reasonable structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool enables rapid and uniform deburring of both interior and exterior burrs, accommodating different sizes and configurations of workpieces, with enhanced cutting ability due to the inclined flutes and acute angles, improving operational efficiency.
Implementation Method 1
rotation of the deburring tool about a longitudinal axis removes burrs projecting from a pipe or a bar stock contacting the interior conical surface

AI summary
A deburring tool includes a deburring head and a shaft portion connected to the deburring head. The deburring head includes a conical hollow body, a primary cutting edge and a secondary cutting edge both formed on the conical hollow body. The conical hollow body has at least one flute extending between interior and exterior conical surfaces of the conical hollow body, and at least one recessed cutout defined in the interior conical surface. The primary cutting edge is formed at a junction of a wall surface of the flute and a bottom surface of the recessed cutout. The secondary cutting edge is formed at a junction of a wall surface of the recessed cutout and the interior conical surface.
