Kink Prevention Jig Structure for Smooth Welding Wire Withdrawal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pail packs for welding wires, even with existing kink prevention measures, still suffer from kink occurrences during continuous use, leading to decreased operation efficiency in automated welding processes.
Innovation Solution
A kink prevention jig is introduced, featuring an outward extending portion and a wire abutting portion that narrows the passage and guides the welding wire to prevent kinks, integrated with the pail pack's inner cylinder, and includes a conical shape to enhance guidance and restrict movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing member is used to prevent wire entanglement, then wire management is improved, but kinks still occur during continuous welding
Solution Approach 1:
A guide member is introduced as an intermediary component between the wire storage chamber and the wire outlet. This guide member includes a guide hole that directs the wire's path, preventing it from twisting or forming loops during withdrawal. The guide member acts as a mediator that controls wire movement without interfering with the pressing member's function, thereby eliminating kinks while maintaining reliable wire withdrawal and high operation rates.
2Length of moving object
If the wire storage space is large to accommodate long wires, then wire length is improved, but wire twisting and kinking increase
Solution Approach 1:
The wire storage system is segmented into two functional zones: a wire storage chamber for holding the coiled wire and a guided withdrawal path. The guide member creates a dedicated pathway that separates the wire's storage position from its withdrawal trajectory. This segmentation allows long wires to be stored without twisting because the guide hole constrains the wire to a specific exit path, preventing random movement and entanglement in the storage space.
3Productivity
If continuous welding is performed to improve productivity, then operation rate is improved, but wire kinks occur more frequently
Solution Approach 1:
The guide member is pre-installed in the wire outlet region to establish a controlled wire path before welding begins. The guide hole is positioned and dimensioned in advance to match the wire diameter and withdrawal speed requirements. This preliminary configuration ensures that during continuous welding operations, the wire automatically follows the predetermined safe path without twisting or kinking, maintaining both high productivity and reliable wire withdrawal throughout the welding process.

AI summary
A kink prevention jig used in a pail pack to prevent kinks when wire is pulled out is provided with a housing that has a base plate part and a tubular outer tube part, and that accommodates a laminated wire and a wire extraction hole thereabove. This kink prevention jig is provided with an outwardly extended section above the laminated wire and that extends in the radial direction of the outer tube part, and a wire abutment section above the outwardly extended section and which abuts on a welding wire W and thereby prevents kinks when the welding wire W is pulled out from the extraction hole.
