Roll Force/Gap Control Device TRIZ Cases
- Rolling Stand Roll Shift Control for Wear Dispersion and Crown Stability
Combining opposite and same-direction roll shifts with screw-down adjustment disperses work-roll wear while maintaining crown and flatness.
- Roll Gap Hydraulic Valve Split for Fast and Precise Positioning
Parallel high-flow and precision valve assemblies let a roll stand change roll gap quickly while maintaining accurate positioning above 200 bar.
- Rolling Mill Chock Position Measurement for Wear-Induced Strip Wedge
Laser-based roll chock position measurement compensates for liner wear, reducing strip wedge and maintenance time in rolling mills.
- Rolling Mill Stand Control for Strip Edge Wave Prevention
Camera-based edge-wave detection adjusts rolling mill stand pivot parameters in real time to keep strip tracking stable and prevent disruptions.
- Cylinder Gap Adjustment for Lubrication-Free Rotary Punching
Rotatable contact members adjust cylinder spacing without lubrication, extending die life and enabling clean food or medical packaging use.
- Rolling Mill Cross-Angle Detection from Backup Roll Load Imbalance
Backup roll load imbalance reveals inter-roll cross angle during open-gap bending, improving zigzagging and camber control without thrust sensors.
- Roll Stand Gap Calibration Using In-Line Strip Thickness Feedback
Strip thickness feedback and stand state data calibrate roll gaps during roll replacement, cutting downtime without stopping the roll train.
- Cylinder Gap Adjustment for Lubrication-Free Punching Dies
Rotating contact members adjust cylinder spacing without lubrication, enabling precise cutting depth and longer flexible die life.
- EDT Embossing of Aluminum Sheet With Low-Reduction Rolling
Low-reduction EDT rolling embosses aluminum sheet with 1-5 μm texture while cutting debris, roll changes, and energy use.
- Width-Zone Cooling Control for Thick Plate Straightening Flatness
Segmented cooling across plate width cuts temperature deviation and improves straightening flatness using measured shape and temperature data.
- Double-Cylinder Edging Roll Adjustment for Fast Hydraulic Stroke
A separately controlled double-cylinder hydraulic layout enables fast edging roll movement with lower pump demand, less leakage risk, and precise gap control.
