Radial Crimping Die Layout to Eliminate Tangential Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crimping tools often experience tangential sliding movements relative to the shielding contact during the crimping process, which can lead to suboptimal surface quality and retention force in crimping connections.
Innovation Solution
A crimping tool design featuring first and second tool parts that can be moved linearly along an axis for opening and closing, with radially movable crimping elements to minimize tangential movement, ensuring a better surface quality and allowing for the use with conventional crimping machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional crimping tools are used with crimping elements moving simultaneously, then the crimping process is simple, but tangential sliding movement occurs relative to the shielding contact
Solution Approach 1:
The crimping tool divides the crimping elements into two separate groups (first and second tool parts), each actuated independently. This segmentation allows different crimping elements to be actuated at different times, preventing tangential sliding while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements dynamic actuation where the first and second tool parts can be actuated sequentially rather than simultaneously. This dynamic control enables the crimping elements to engage the shielding contact in a controlled manner, eliminating unwanted tangential sliding movements during the crimping process.
2Manufacturing precision
If the crimping tool is designed to eliminate tangential sliding, then surface quality improves, but the tool complexity increases
Solution Approach 1:
By segmenting the tool into first and second tool parts with separate actuation mechanisms, the patent achieves precise control over the crimping process. Each part can be actuated independently to optimize the crimping sequence, improving retention force without requiring an overly complex single integrated system.
Solution Approach 2:
The patent employs preliminary action by positioning and actuating the first tool part before the second tool part. This sequential approach allows the initial crimping elements to establish proper alignment and contact, preventing tangential sliding before the remaining elements engage, thereby improving retention force with controlled complexity.
3Adaptability or versatility
If conventional crimping dies are used, then the tool structure is compact, but larger work pieces cannot be accommodated
Solution Approach 1:
The patent implements a dynamic opening mechanism where the first and second tool parts can be moved apart completely, allowing the crimping dies to open fully. This dynamic capability enables accommodation of larger work pieces while maintaining a compact structure when closed, as the tool parts can be positioned close together during operation.
Solution Approach 2:
By dividing the crimping tool into separable first and second tool parts, the patent enables the crimping dies to open completely for inserting larger work pieces. The segmented structure allows each part to move independently, providing the necessary opening space while maintaining structural integrity and compactness during the crimping operation.
