Curved Tire Flash Cutting Tool for Automatic Burr Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing excess rubber from tire vulcanization, such as manual removal with a V-shaped knife, are inefficient and can cause tire damage, noise emissions, and poor tire seating on the rim.
Innovation Solution
A cutting tool with a bracket for a removable cutting insert, featuring a curved design that allows the tool to slide on the tire and cut the vulcanization ridge without pushing it away, thereby preventing distortion and allowing for effective automatic detection and removal of ridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual removal with a V-shaped knife is used, then the cutting action can be performed, but the tire can be damaged and noise emissions increase
Solution Approach 1:
The cutting tool features a curved body that allows it to slide along the tire surface rather than push against it. This curved geometry enables the tool to follow the tire contour and cut the flash material efficiently without causing damage or excessive noise, directly resolving the contradiction between cutting capability and harmful effects.
2Ease of operation
If the cutting tool pushes the burr away, then the cutting action is simpler, but the burr becomes distorted
Solution Approach 1:
The curved body of the cutting tool enables it to slide along the tire surface, pulling the flash material through the cutting edges rather than pushing it away. This sliding motion maintains burr integrity while keeping the operation simple, resolving the contradiction between ease of operation and manufacturing precision.
3Productivity
If automatic burr removal is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The cutting tool is designed to be self-guiding through its curved geometry, which naturally follows the tire contour and positions the cutting edges correctly. This self-service capability enables automatic burr removal without requiring complex positioning systems, resolving the contradiction between productivity and device complexity.
