Interchangeable Threaded Rod Shear Jaws for Portable Multi-Rod Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shearing tools for threaded rods are limited in versatility, requiring specific locations, are often heavy and not portable, and rely on corded power, which can be inconvenient, especially in jobsites without power outlets, and they do not efficiently handle multiple rods at once.
Innovation Solution
A shearing tool system with a tool head and dies that includes a pair of pivotally connected jaws, allowing for the use of a power assembly with a handle and motor, enabling the shearing of multiple rods simultaneously using a quick release clamp and dissimilar dies that can be easily detached and reattached, and operated with battery power for portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dedicated shearing tools are used for specific locations, then shearing precision is improved, but versatility and adaptability deteriorate
Solution Approach 1:
The die assembly is designed to be universally compatible with multiple power tool types (drills, impact drivers, screwguns) through a standardized mounting interface. The quick-release die mechanism allows the same tool body to perform shearing operations on rods of various sizes by simply changing the die insert, making the tool adaptable to different job requirements while maintaining precise shearing capability.
2Force
If high tonnage shearing equipment is used, then shearing force is improved, but portability and ease of movement deteriorate
Solution Approach 1:
The shearing system is segmented into a lightweight tool body and separate interchangeable die assemblies. The die contains the heavy-duty shearing components and is quickly swapped as needed. This segmentation allows the main tool to remain portable and easy to move around the jobsite, while still delivering high tonnage shearing force when the appropriate die is attached.
3Power
If corded shearing tools are used, then continuous power is improved, but ease of operation and accessibility in remote locations deteriorate
Solution Approach 1:
The tool is designed with a universal power interface that can accept multiple power sources including battery packs and corded power supplies. This allows the user to operate the shearing tool in remote locations using battery power, or connect to electrical outlets when available, providing both mobility and continuous power capability.
4Manufacturing precision
If multiple rods are sheared sequentially, then precision is maintained, but productivity and time efficiency deteriorate
Solution Approach 1:
The die assembly incorporates multiple shearing edges or surfaces that can simultaneously shear multiple rods positioned in the tool's jaws. This allows the user to shear several rods in a single operation, maintaining precise cuts on all rods at once, thereby significantly improving productivity without sacrificing cut quality.
