Metal Pipe Forming Power Line Routing for Magnetic Field Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing forming systems generate a significant leakage magnetic field from the power supply line, which affects peripheral equipment, and there is a need to suppress this influence to ensure efficient operation and minimize interference.
Innovation Solution
The forming system design includes a power supply line that passes through the lower side of the placing surface, with parallel positive and negative electrode lines to cancel magnetic fluxes, and strategically routed connection portions to avoid interference with other equipment, thereby reducing the leakage magnetic field's impact on peripheral equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the power supply line is routed through the main body part, then connectivity is maintained, but leakage magnetic field affects peripheral equipment
Solution Approach 1:
The power supply line is extracted from the main body part and routed through the lower side of the placing surface. This separates the power supply line from the forming die area, eliminating the leakage magnetic field's interference with peripheral equipment while maintaining electrical connectivity through the lower-side passing portion.
Solution Approach 2:
The power supply line routing is moved from the horizontal plane (through the main body) to the vertical dimension (through the lower side of the placing surface). This spatial reconfiguration allows the line to pass beneath the placing surface, avoiding magnetic field interference with equipment on the placing surface while maintaining connection.
2Object-affected harmful factors
If the power supply unit is placed close to the main body part, then connection is simplified, but magnetic field interference with peripheral equipment increases
Solution Approach 1:
The power supply unit is extracted from the immediate vicinity of the main body part and positioned at a separated location. The power supply line connects these separated components by passing through the lower side of the placing surface, reducing magnetic field interference while maintaining functional connectivity.
3Reliability
If the power supply line passes through the placing surface, then connectivity is maintained, but magnetic field affects equipment on the placing surface
Solution Approach 1:
The power supply line passes through the lower side of the placing surface rather than through the placing surface itself. This vertical routing through the lower side maintains electrical connectivity while positioning the line below the equipment on the placing surface, eliminating magnetic field interference.
Solution Approach 2:
The lower side of the placing surface acts as an intermediary medium that the power supply line passes through. This intermediary routing path allows the line to connect components while remaining spatially separated from equipment on the placing surface, thus maintaining connectivity without causing interference.

Function Achieved in This Case
This configuration effectively suppresses the influence of the leakage magnetic field on peripheral equipment, allowing for improved system operation and reduced interference, while also optimizing the path of the power supply lines to minimize resistance and maintain connectivity.
Implementation Method 1
an electrode causing an electric current to flow through the metal pipe material disposed in the forming die such that the metal pipe material is heated
Implementation Method 2
The power supply line includes a lower-side passing portion which passes through a lower side of a placing surface on which the main body part is placed, a first connection portion which is drawn to an upper side than the placing surface and connects the lower-side passing portion and the electrode, and a second connection portion which connects the lower-side passing portion and the power supply unit
