Drawing Mandrels TRIZ Cases
- Stepped Forming Mandrel for Uniform Hollow Body Cavity Profiles
A stepped mandrel compensates uneven elastic recovery during hollow body forming, preserving cavity size for easier counterpart insertion.
- Stepped Forming Mandrel for Hollow Body Wall Profile Recovery
A stepped mandrel compensates for elastic recovery in hollow body walls, preserving cavity clearance for easier counterpart insertion.
- Sensorized Drawing Mandrel for Precise Tube Forming Monitoring
A mandrel-mounted sensor measures position, temperature, pressure, and acceleration inside the tube to improve drawing process control.
- Tubular Hollow Body Forming for Precise Internal Toothing
Rotating die and mandrel shaping improves filling of internal tooth profiles in tubular hollow bodies while avoiding material compression.
- Tubular Hollow Body Shaping With Coordinated Die-Mandrel Motion
Coordinated die and mandrel motion reduces tubular cross-section under tensile stress, preventing compression and enabling high-speed shaping.
- Hollow-Fiber Metal Microfibers for Flexible Conductive Wiring
Liquid metal is injected into hollow fibers and drawn at room temperature to create flexible conductive microfibers with controlled thickness and modulus.
- Tubular Hollow Body Internal Profiling With Rotating Die and Mandrel
Relative die-mandrel rotation improves material flow to form precise internal teeth in tubular hollow bodies while limiting compression.
- Tube End Expansion and Indentation for Floating Mandrel Insertion
Automated tube end expansion and indentation improve floating mandrel positioning, reduce manual errors, and support efficient slide drawing.
- Dual-Ply Bellows Conduit for Cryogenic Displacement and Leak Sensing
An interstitially monitored dual-ply bellows conduit detects leaks while absorbing displacement in cryogenic propellant feed lines.
- Cold Drawing Plug Tapered Geometry Reduces Residual Stress
A segmented cold drawing plug uses a tapered portion to expand metal pipes and improve surface finish.
- Telescopic Steering Column Inner Tube with Polygonal Cross-Section
Polygonal cross-section inner tube reduces material mass while maintaining bearing support capability.
