Parallel Crimping Plier Mold Replacement for Symmetric Terminal Crimping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crimping pliers often result in asymmetrical and deformed terminals due to the asymmetrical crimping process, leading to damage and inefficiency, as they require replaceable crimping modules for different terminals and wires.
Innovation Solution
A cavity mold-replacing structure for parallel crimping pliers that allows quick and even crimping of terminals by using a mold-replacing block to adjust the cavity mold components, ensuring symmetrical crimping and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional crimping pliers are used with asymmetrical crimping process, then the crimping operation can be performed, but the terminals become asymmetrical and deformed
Solution Approach 1:
The patent inverts the traditional crimping approach by using parallel movement of crimping parts instead of rotational movement. The first and second crimping parts move parallel to each other toward the terminal, ensuring symmetrical crimping without the asymmetry caused by rotation around a fulcrum.
Solution Approach 2:
The crimping device is segmented into independent first and second crimping parts that can move independently in parallel. This segmentation allows each crimping part to apply force symmetrically to opposite sides of the terminal, preventing deformation.
2Adaptability or versatility
If replaceable crimping modules are used for different terminals, then adaptability to different terminal types is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal cavity mold component that can be quickly replaced to accommodate different terminal types. The mold-replacing component allows the same crimping device to handle various terminal specifications by simply changing the cavity mold, rather than requiring entirely different crimping modules.
Solution Approach 2:
The cavity mold component is designed to be dynamically replaceable through the mold-replacing component. This allows the device to adapt its functionality for different terminal types while maintaining a relatively simple overall structure, as the replacement mechanism is integrated into the existing parallel crimping framework.
3Productivity
If quick replacement of cavity molds is implemented, then work efficiency is improved, but device complexity increases
Solution Approach 1:
The mold-replacing component is designed to enable preliminary positioning and quick engagement of the cavity mold component. The replacing block can be inserted and the mold quickly secured in place before crimping operations begin, allowing for rapid tool changes without complex adjustment procedures.
Solution Approach 2:
The replacing block serves as an intermediary component between the operator and the cavity mold. This mediator element simplifies the replacement process by providing a straightforward insertion and engagement mechanism, reducing the complexity of direct mold handling while enabling quick changes.
