Metal Forming Transfer Holding for Hole-Free Precise Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In forming systems that expand and deform metal materials, such as high-pressure gas expansion forming, it is not possible to form reference holes in the preliminary stage due to gas leakage, which hinders accurate positioning and increases positional and phase deviations during the forming process.
Innovation Solution
The forming system includes a transport device that holds the metal material in a gripped state throughout its transport and treatment processes, maintaining alignment and preventing deviations, and a marking unit that marks the formed product to provide accurate positioning information for post-machining, allowing for precise machining despite the absence of initial reference holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reference holes are formed in the preliminary stage, then positioning accuracy is improved, but gas leakage occurs during high-pressure gas expansion forming
Solution Approach 1:
The transport device performs preliminary positioning and gripping of the metal material before the forming process. By establishing the correct position and orientation in advance while the material is still rigid, the system eliminates the need for reference holes that would cause gas leakage during expansion forming.
Solution Approach 2:
The transport device acts as an intermediary that maintains the metal material in a gripped state throughout transport and into the forming device. This continuous holding mechanism ensures positional integrity without requiring reference holes in the material itself, thereby preventing gas leakage while maintaining positioning accuracy.
2Device complexity
If the metal material is transported without holding, then the transport process is simpler, but positional and phase deviations increase during forming
Solution Approach 1:
The transport device maintains a continuous gripped state on the metal material from transport through to positioning in the forming device. This continuous holding action ensures that the material maintains its positioned state without deviation, achieving high manufacturing precision while the gripping mechanism is integrated into the transport device to avoid excessive complexity.
