Deburring Blade Helical Transition to Prevent Secondary Burrs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring blades face challenges in manufacturing accuracy and quality due to high requirements for interlocking cutting and control edges, leading to undesirable secondary burrs during the chamfering or deburring process.
Innovation Solution
A deburring blade with a helically twisted surface that provides a continuous transition from the cutting to the non-cutting part, eliminating the need for a gusset and simplifying manufacturing, while maintaining precise chamfering and deburring quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a gusset transition surface is used to connect cutting and control surfaces, then the structural integrity is maintained, but manufacturing accuracy requirements increase and secondary burrs are generated
Solution Approach 1:
The patent removes the gusset transition surface from the cutting blade design. By eliminating this problematic intermediate structure, the invention avoids the manufacturing accuracy issues and secondary burr generation that the gusset caused, while still achieving the necessary transition from cutting to control surface through a direct adjacent arrangement.
Solution Approach 2:
Instead of using an intermediate gusset structure to connect the cutting and control surfaces, the invention inverts the approach by making the cutting surface and control surface directly adjacent to each other. This reversal of the transition mechanism eliminates the need for the problematic gusset structure entirely.
2Stability of the object's composition
If two surfaces are used to transition from cutting to non-cutting part, then the structural stability is maintained, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the transition function into a simpler direct adjacency arrangement between the cutting surface and control surface. By combining what was previously a multi-surface transition (cutting surface + gusset + control surface) into a direct connection, the invention reduces structural complexity while maintaining stability through the continuous support of the blade body.
3Manufacturing precision
If cutting edge and free edge must interlock for desired effect, then deburring quality improves, but manufacturing precision requirements become excessively high
Solution Approach 1:
The invention removes the requirement for interlocking cutting and free edges by eliminating the gusset structure that created this requirement. The direct adjacency of the cutting surface to the control surface allows for effective deburring without the need for precise interlocking, significantly easing manufacturing requirements.

AI summary
The invention relates to a deburring blade for deburring the edges of holes on workpieces, containing at least one cutting blade, which comprises at least one cutting portion having at least one cutting edge with an associated free surface which is designed as a cutting part, an associated control surface adjoining the cutting edge and being designed as a non-cutting part, the cutting blade being held in a tool holder which is rotatable about an axis of rotation in at least one direction of rotation, and the cutting edge transitioning into a helically twisted surface which forms a continuous transition from the cutting part to the non-cutting part.
