Problems solved by technology
After the probe head is damaged, due to the high price and generally no inventory (a pair of probes is about 60,000 yuan, and a set of mold control device is about 70,000 yuan), the spare parts order cycle takes 4 months. The probe is damaged and there are no spare parts. The system cannot work, which seriously affects the normal operation of the cold rolling mill and reduces production efficiency

The invention discloses an automatic centering logic numerical control device of a cold-rolled strip steel uncoiler. The device adopts three infrared photoelectric sensors to detect the strip steel deviation and the strip steel uncoiling threading, adopts two electromagnetic induction switches to detect the displacement signal of the uncoiler, adopts a limit switch to detect the movement limit of the width fixing block on a screw, and adopts a velocity measurement generator to detect the velocity signal of the driving motor of the uncoiler and to feedback the velocity signal to a proportion amplifier; a detection signal is provided to a logic control circuit formed by a button and a relay; and the control circuit controls an uncoiler pedestal centering, deviation correcting and width fixing execution mechanism to realize the uncoiler pedestal automatic centering, strip steel uncoiling threading detection, strip steel automatic edge tracking and width fixing, strip steel deviation correction functions, so the equipment maintenance cost can be effectively reduced, and the normal running of a cold rolling unit is guaranteed.
Description
technical field [0001] The invention relates to an automatic centering logic numerical control device for a cold-rolled strip uncoiler. Background technique [0002] The uncoiler of the cold rolling unit can move laterally between the transmission side and the operation side of the conventional process, and under the control of the centering device, the strip steel can be kept at the center of the rolling mill production line. [0003] The drive motor drives the tensioning shaft of the uncoiler through the gearbox to realize the uncoiling of the steel coil. After the coil is uncoiled, the steel strip moves forward in the C-shaped frame. A screw rod with opposite threads is installed on the C-shaped frame. The two ends of the screw rod are respectively equipped with The fixed width block, the screw is driven by the fixed width motor, and the width of the strip on the C-frame is realized through the fixed width block according to the width of the strip steel. The lateral movem...
