Repositionable Hydraulic Crimp Die Set
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic crimp tools require multiple die sets to perform different crimping operations, as the crimp dies are typically fixed and cannot be easily repositioned, leading to increased time and inventory needs for technicians.
Innovation Solution
The development of repositionable crimp die sets for hydraulic crimp tools, where each die can be interchangeably positioned within the working head to secure wire connectors from various orientations, utilizing identical dies with semi-circular, circumferential, or hexagon impacting surfaces and coupling members for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple die sets are used to perform different crimping operations, then various crimping orientations can be achieved, but inventory requirements and setup time increase
Solution Approach 1:
A single die set is designed with multiple die blocks that can be positioned in different orientations within the working head. Each die block can be rotated to different angular positions (0°, 45°, 90°, 135°, etc.) to perform various crimping operations, making one die set universal for multiple crimping orientations rather than requiring separate dedicated die sets for each orientation
Solution Approach 2:
The die blocks are made repositionable within the working head through a mechanism that allows rotation and repositioning at different angular positions. This dynamic capability enables the same die block to serve multiple functions by changing its orientation, eliminating the need for multiple static die sets
2Adaptability or versatility
If multiple die sets are used for different crimping operations, then all required crimp orientations can be performed, but time to change die sets increases
Solution Approach 1:
The die blocks are designed to be repositionable within the working head, allowing operators to rotate and reposition the same die block to different angular positions for various crimping operations. This eliminates the time-consuming process of physically changing entire die sets, as only the orientation of individual die blocks needs to be adjusted
Solution Approach 2:
The die set is segmented into multiple independent die blocks that can be individually positioned and oriented. This segmentation allows each die block to be independently repositioned to the required orientation without affecting other die blocks, enabling quick reconfiguration for different crimping operations
3Quantity of substance
If identical dies are used with repositioning capability, then inventory is reduced, but the complexity of the die mounting mechanism increases
Solution Approach 1:
A repositioning mechanism is provided that allows die blocks to be rotated and positioned at different angular orientations within the working head. The mechanism includes features such as rotatable mounts, indexing positions, and locking features that enable the same die block to be securely positioned in multiple orientations (0°, 45°, 90°, 135°, etc.)
Solution Approach 2:
The die blocks are pre-configured with mounting features and the working head is pre-equipped with corresponding mounting mechanisms that facilitate easy repositioning. The system is designed beforehand to accommodate multiple die orientations, so operators can quickly reposition dies without complex adjustments or custom modifications
