Rotatable Crimping Pliers Die for Flexible Wire Sleeve Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping pliers dies lack flexibility in accommodating different workpiece orientations and sizes, leading to inefficiencies in crimping operations due to fixed insertion depths and limited adaptability.
Innovation Solution
The crimping pliers die incorporates a stop body with adjustable insertion stops and a rotational bearing system, allowing for various insertion depths and orientations, and utilizes die halves with ribs for precise crimping, along with a guiding mechanism for enhanced precision and stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed die design is used, then the device complexity is reduced, but the adaptability to different workpiece orientations and sizes deteriorates
Solution Approach 1:
The die half units are designed to be rotatable relative to each other about a rotational axis, allowing the die accommodation to be oriented in different positions (first rotational position for longitudinal insertion, second rotational position for lateral insertion). This dynamic reconfiguration enables the same die to accommodate different workpiece orientations and sizes without requiring multiple fixed die designs.
2Adaptability or versatility
If multiple specialized dies are used for different workpieces, then the adaptability is improved, but the device complexity and component diversity increase
Solution Approach 1:
The die half units are designed as universal components that can perform multiple functions: they can be rotated to different orientations to accommodate different workpiece sizes and types, and they maintain precise guiding and support functions across all orientations. This multi-functionality eliminates the need for multiple specialized dies for different workpiece types.
3Manufacturing precision
If guiding rods and guiding recesses are used, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The guiding rods and guiding recesses are integrated as built-in features of the die half units themselves, rather than being separate external components. The guiding rods are formed as extensions of the die half units, and the guiding recesses are formed directly in the opposing die half units, merging the guiding function into the crimping structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances operational flexibility, improves crimping precision, and accommodates different workpiece sizes and orientations, leading to improved crimping results and reduced component diversity.
Implementation Method 1
The rotational bearing allows a rotation of the die halves about a rotational axis having an orientation coaxial or parallel to the crimping axis
Implementation Method 2
The guiding rod of one die half unit is then guided for being displaced along the crimping axis in the associated guiding bore of the other die half unit

AI summary
The invention relates to a crimping pliers die (1) comprising two die half units (2, 3). The die half units (2, 3) are guided by a guide (51) relatively to each other over the crimping stroke. Crimping surfaces (40, 41) of the die halves (5) are formed by front surfaces of engaging ribs (37). Preferably, the guide (51) comprises a guiding rod (43) formed by an end-sided thickening (42) of a rib (37) and the guide (51) comprises a guiding recess (50) formed by a guiding recess section (45) which connects two ribs (37) to each other.The crimping pliers die (1) can be used for crimping pliers which can e. g. be used for crimping wire end sleeves.
