Crimping Pliers Head with Sliding Inserts for Force Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crimping tools face limitations in accommodating work pieces of different types, diameters, and contours due to limited nest halves per insert, leading to suboptimal force distribution and potential deformations, which result in incomplete crimping and undesired ridges or flashes.
Innovation Solution
The crimping tool design allows for the movement of inserts between two relative positions, enabling the use of a greater number of nest halves and optimizing force distribution by aligning the nest halves with the 'force center', thus minimizing bending moments and ensuring precise crimping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional crimping tools use limited nest halves per insert, then the device complexity is reduced, but the manufacturing precision deteriorates due to suboptimal force distribution and potential deformations
Solution Approach 1:
The insert is designed with translational degrees of freedom, allowing it to move dynamically between different operational positions along the crimping axis. This dynamic capability enables the same insert to accommodate multiple nest halves at different locations, optimizing force distribution for various crimping scenarios without increasing device complexity
Solution Approach 2:
A single insert design serves multiple functions by incorporating the capability to hold and position multiple different nest halves. The insert can be positioned at different locations along the crimping axis to accommodate nests of various sizes and types, making one insert universally applicable for different crimping requirements
2Adaptability or versatility
If more nest halves are accommodated per insert, then the adaptability is improved for different work pieces, but the device complexity increases
Solution Approach 1:
The insert incorporates translational degrees of freedom that allow it to move along the crimping axis, enabling a single insert structure to accommodate multiple nest halves at different positions. This dynamic positioning capability provides adaptability for different work piece types, diameters, and contours without requiring multiple complex insert structures
Solution Approach 2:
The insert is designed as a modular component that can be positioned at different locations along the crimping axis. Each position can accommodate different nest halves, effectively segmenting the insert's functionality into multiple operational states that can be selected based on the specific work piece requirements
3Ease of operation
If nest halves are positioned away from the force center, then the ease of operation is improved for accessing different nests, but the manufacturing precision deteriorates due to increased bending moments and deformations
Solution Approach 1:
The insert is designed with translational degrees of freedom that allow it to move dynamically to position nest halves optimally relative to the force center during crimping operations. This dynamic positioning ensures that nests are accessed at locations that minimize bending moments while maintaining ease of operation
Solution Approach 2:
The position of the insert along the crimping axis can be changed to optimize the location of nest halves relative to the force center. By adjusting the insert's position parameter, the system achieves optimal force distribution and minimizes deformations while maintaining accessibility for different crimping scenarios

AI summary
The present invention relates to a head of crimping pliers for crimping a work piece. The head comprises two inserts. Each insert builds at least two halves of at least two nests for the work piece. The inserts are guided along a guiding axis for a sliding movement between a first and second relative position. The guiding axis is directed transverse to the crimping axis. Two nests built by the halves might be used in one and the same position by moving the inserts from the first to the second relative position.
