ROLL-FORMING UNIT WITH SENSOR-ROLL-FORMING FRAME

摘要

The present invention relates to a method and to a corresponding roll-forming unit with a plurality of roll-forming frames arranged one after the other, wherein at least one of the roll-forming frames is designed as a sensor roll-forming frame (5), wherein when the metal strip is passed through the roll-forming unit, at least one force is measured on the sensor roll-forming frame (5) and a sensor signal is generated. Preferably, during a test run, a setpoint value of the sensor signal and a tolerance range are determined, with which the sensor signal in an operating state is compared. In the operating state, a microprocessor unit uses a detection algorithm to compare the sensor signal with the setpoint value and/or with the tolerance range, and detects a first or at least one second state of the sensor roll-forming frame (5), which displays a measurement for process compliance or an early diagnosis for a deviation.
