A hollow piece shape and a tool shape such that the external diameter is within ±1% of the target, the thickness is within ±7.5% of the target, and the internal gap between the hollow piece and the tool is 1.0 mm or less are obtained by repeated calculation, and thereby actual tube expanding manufacturing conditions are determined."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tube expanding method for manufacturing metal tube","description":"Through a tube expanding processing simulation, a workpiece shape in a state where a tip of a workpiece 10 has advanced by 1.0 m or more after passing through a shoulder portion 3 of a tool 1 is evalu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9707614","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
