Trimming Tool with Movable Blade for Variable Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for trimming motor vehicle body stampings are expensive due to the need for multiple stamping presses with specific tooling for different wheel arch profiles, limiting the ability to efficiently trim according to various profiles.
Innovation Solution
A trimming tool with a movable frame and adjustable cutting blades that can switch between two cutting profiles using elastic means and locking mechanisms, allowing a single press to handle different trimming profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple stamping presses with specific tooling are used for different wheel arch profiles, then trimming accuracy for different profiles is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The trimming tool is designed with a movable blade that can be positioned in different locations to define different cutting profiles. A single stamping press with this adjustable tooling can trim wheel arches for multiple vehicle models, eliminating the need for multiple dedicated presses and reducing device complexity while maintaining trimming accuracy
Solution Approach 2:
The blade is made movable along the support surface, allowing its position to be changed dynamically. This enables the same tool to adapt to different trimming profiles by repositioning the blade, rather than requiring fixed tooling for each profile
2Adaptability or versatility
If multiple stamping presses with specific tooling are used for different wheel arch profiles, then trimming capability for various profiles is improved, but manufacturing cost increases
Solution Approach 1:
The tooling design allows a single press to perform trimming operations for different vehicle models and wheel arch profiles by adjusting the blade position. This multi-functionality eliminates the need to manufacture multiple expensive presses, significantly reducing manufacturing costs while maintaining versatility
Solution Approach 2:
The cutting profile is segmented into different sections, with the blade capable of being positioned at different locations along the support surface. This segmentation allows the same tool to create different trimming profiles by selecting which segment of the support surface engages with the blade
3Ease of manufacture
If a single press with adjustable tooling is used, then manufacturing cost and device complexity are reduced, but the ability to switch between different trimming profiles may be limited
Solution Approach 1:
The blade is designed to be movable along the support surface, enabling dynamic repositioning to accommodate different trimming profiles. This dynamic capability allows a single press to handle multiple profiles, maintaining adaptability while reducing the need for multiple presses
