Welding Nozzle Cleaning Tool with Dual Pinchings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand tools for welding-torch maintenance require separate processes for removing sputter from the inner and outer circumferential surfaces and the end face of the nozzle, leading to inefficient working efficiency.
Innovation Solution
A hand tool with a pair of metal stays crossing at a pivoting axis, equipped with 1st and 2nd pinchings, where the 1st pinchings are inserted into the nozzle and the 2nd pinchings have projections and concave spaces to facilitate the removal of sputter from all surfaces by scratching, allowing for efficient removal of sputter from the inner, outer, and end faces of the nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate processes are used for removing sputter from inner/outer circumferential surfaces and end face of the nozzle, then each surface can be cleaned, but working efficiency is reduced
Solution Approach 1:
The patent combines multiple sputter removal operations (inner circumferential surface, outer circumferential surface, and end face cleaning) into a single integrated process using one hand tool configuration. The metal stays are positioned to simultaneously access all three surfaces of the nozzle, allowing complete sputter removal in one operation rather than requiring separate processes for each surface.
Solution Approach 2:
The hand tool is designed with multi-functional metal stays that can perform multiple cleaning functions. The same metal stay structure is used to clean the inner circumferential surface, outer circumferential surface, and end face of the nozzle, making the tool universal for all sputter removal tasks on the nozzle without requiring tool changes or additional specialized components.
2Reliability
If multiple separate operations are performed for nozzle maintenance, then thorough cleaning is achieved, but time consumption increases
Solution Approach 1:
The patent enables continuous cleaning action across all nozzle surfaces without interruption. The metal stays are configured to maintain contact with the nozzle surfaces throughout the movement, allowing the operator to clean the inner circumferential surface, outer circumferential surface, and end face in a continuous motion rather than stopping and repositioning between operations, thus eliminating idle time while maintaining thorough cleaning.
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
Enables efficient removal of sputter from all surfaces of the nozzle by integrating the processes into a single operation, improving working efficiency and accommodating various nozzle shapes and sizes.
Implementation Method 1
a pair of metal stays 10 crossing at a pivoting axis 11 and turnably supported by the axis
Implementation Method 2
the 1st pinchings 13 may scratch the inner-and-outer circumferential surfaces. Thereby, the sputter adhering to the inner-and-outer circumferential surfaces of the nozzle is scratched off and removed

AI summary
A hand tool for welding-torch maintenance, which can remove sputter adhering to a nozzle with sufficient working efficiency. The hand tool has a pair of metal stays turnably supported by a pivoting axis. The metal stays comprises grips handled by a user, 1st pinchings used for pulling a welding-wire, and 2nd pinchings used for removing sputter adhering to the nozzle. The 1st pinchings are configured so as to be inserted into the nozzle when the metal stays are closed. The 2nd pinchings have projections which are extended outside from the backs of the 1st pinchings and thrown out towards heads of the 1st pinchings. The sputter adhering to the inner-and-outer circumferential surfaces and end face of the nozzle are removed by inserting the 1st pinchings into the nozzle, inserting the end of the nozzle between the 2nd pinchings and the 1st pinchings, and moving the tool to scratch the sputter off the inner-and-outer circumferential surfaces and the end face of the nozzle.
