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.
- Plate Straightening Control with Patterned Cooling for Flatness
Patterned cooling across plate width cuts temperature deviation and lets straightening settings adapt to measured flatness and shape.
- Stepped Metal Strip Rolling With Constant Force Tension Control
Strip tension is adjusted during stepped rolling to keep rolling force nearly constant, preventing levelness defects at high speed.
- Rolling Mill Leveling Control Using Multi-Stand Torque Data
Multi-stand torque data helps infer strip tension and guide upstream screw-down corrections, improving curvature control at high rolling speeds.
- Asymmetric Rolling Apparatus for Magnesium Formability
Differential roll speeds apply asymmetric shear stresses to develop basal plane slip systems, improving magnesium formability at room temperature.
- Roll Eccentricity Suppression via Tensile Force Feedback
Process model identifies roll eccentricities using upstream tensile force measurements to generate correction signals for the rolling stand actuator.
- Cold Roller Mass Flow Regulation via Speed and Thickness Feedback
A control device adjusts circumferential roll speed based on actual strip velocity to maintain precise mass flow rates.
- Roll Gap Coolant Distribution for Strip Thickness Control
Dynamic zone-based coolant distribution compensates for local power variations to maintain thickness uniformity and prevent overheating.
- Non-axisymmetric Deep Rolling Tool for Complex Geometries
A non-axisymmetric deep rolling tool uses a spring-loaded shaft and angled hub to apply compressive stress on workpieces.
- Inferential Thickness Control Using Kalman Filter
Kalman filter infers sheet metal thickness to compensate for time-varying delays and roll eccentricity.
- Roll Gap Control for Wedge Strip Flatness
Asymmetric actuator control compensates for wedge-shaped strips, eliminating flatness errors and reducing material rejection.
- Rolling Stand Eccentric Bushing Force Measurement
A rolling stand eccentric bushing uses a low-friction bearing unit to enable precise adjusting force measurement.
- Rolling Mill Thickness Control via Integrated Regulator
A single regulator corrects roll spacing using downstream thickness measurements and flow rate predictions.
- Hydraulic Orifice and Chamber Design for Rolling Mill Vibration Control
An expanding chamber paired with a specific orifice diameter enhances dynamic stiffness to control mill vibration without causing dust clogging.
- Cold-Rolling Line Thickness Control via Upstream Measurement
Upstream thickness measurement and speed detection resolve control dead time by enabling high-frequency disturbance correction at the penultimate roll stand.
