Crimping Tool Die With Integral Rib Guide Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping tool dies face limitations in design flexibility, workpiece compatibility, and assembly complexity, particularly in ensuring precise alignment and mechanical strength, which hinders efficient crimping of various ferrule types with cables.
Innovation Solution
The crimping tool die features die halves with interlocking ribs and a guide system comprising guide rods and recesses, allowing for adjustable alignment and increased mechanical strength through integral rib-based guide rods and segment-shaped guide surfaces, enabling crimping of ferrules with enhanced precision and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If guide rods are formed as separate components attached to die halves, then assembly is simplified and manufacturing is easier, but alignment precision and mechanical strength are reduced
Solution Approach 1:
The guide rod is merged with the rib structure of the die half, forming an integral component where the guide rod is formed by a thickened end area of the rib. This integration ensures precise alignment between guide rods and guide recesses while maintaining mechanical strength, eliminating the need for separate attachment operations.
2Manufacturing precision
If guide rods are formed by thickened end areas of ribs, then alignment precision and mechanical strength are improved, but assembly complexity increases
Solution Approach 1:
The guide rod is integrated into the rib structure as an integral feature, forming a unified component that reduces the total number of parts. This merging simplifies assembly by eliminating separate guide rod attachment steps while ensuring precise alignment through the thickened end area design.
3Device complexity
If die halves have continuous convex and concave crimping surfaces, then structural simplicity is maintained, but versatility for different workpiece types is reduced
Solution Approach 1:
The continuous crimping surfaces are segmented into multiple ribs with varying configurations. Each rib can be independently designed with different heights, positions, and cross-sectional shapes, allowing the die halves to accommodate various workpiece types while maintaining a relatively simple overall structure based on the rib framework.
4Manufacturing precision
If multiple guide rods and guide recesses are provided, then alignment precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Instead of uniformly distributing multiple guide rods, the invention provides guide rods only at specific locations where alignment is most critical. The guide rods are formed by thickened end areas of specific ribs, concentrating guidance functionality where needed while maintaining simplicity elsewhere in the structure.

AI summary
The invention relates to a crimping die (1) with two die halves (2, 3). The die halves (2, 3) are guided relative to each other over the crimping stroke by means of a guide (51). Crimping surfaces (40, 41) of the die halves (5) are formed by end faces of interlocking ribs (37). The guide (51) has a guide rod (43) formed by an end-end thickening (42) of a rib (37), and/or a guide recess (50) formed by a guide recess area (45) connecting two ribs (37). The crimping die (1) is used for crimping pliers, which can be used, for example, for crimping wire ferrules.
