Rollforming machine with sensor roll forming frame

摘要

The present invention relates to a method and a corresponding roll forming system with a plurality of roll forming stands arranged one behind the other, wherein at least one of the roll forming stands is designed as a sensor roll forming frame 5, wherein at least one force is measured and transmitted when the sheet metal strip is passed through the roll forming installation on the sensor roll forming frame 5 Sensor signal is generated. Preferably, during a test run, a desired value of the sensor signal and a tolerance range is determined, against which the sensor signal is compared in an operating state. In the operating state, a microprocessor unit with a detection algorithm compares the sensor signal with the desired value and / or with the tolerance range and detects a first or at least one second state of the sensor rollform frame 5, which is a measure of process compliance or indicates an early diagnosis of a deviation ,
