The uncoiler is a key device of the head of the cold rolling unit, and the state of the uncoiler is directly related to whether the unit is normally produced and stably operated. The cold rolling uncoiler is widely applied to cold-rolled strip steel workshops, and all units taking strip coils as blanks, such as continuous pickling, shearing, continuous heat treatment, boundary coating and the like, are required to be provided with the uncoiler to finish uncoiling, straight head, feeding and other procedures. Therefore, it is very important to accurately grasp the device operation state of the unwinder.
The cold rolling uncoiler is used for uncoiling a steel coil and keeping the steel coil continuously working and consists of a mandrel, a transmission system and an outer supporting device. The mandrel is driven by a motor to rotate to finish normal uncoiling action, and simultaneously, the mandrel is expanded and contracted through an expansion and contraction cylinder to be matched with a coiling trolley to finish coiling action. The transmission system transmits the torque of the motor to the mandrel through the two-stage gearbox, so that the mandrel rotates. The outer supporting device ensures that the mandrel cannot deform when the maximum unreeling amount is achieved, and the reeling trolley is ensured to automatically reel.
The uncoiler of a certain cold rolling mill has continuous faults, various faults such as burning of a motor sliding bearing, damage of a transmission gear box bearing, high temperature of a reduction gear box bearing, cracking of copper sliding strips, shoulder breakage of sector blocks, sliding and clamping of a rectangular pyramid sleeve caused by severe abrasion of a roll key slot, expansion and shrinkage of a roll, displacement of a base frame of the uncoiler and the like occur, so that a large number of spare parts are consumed, and production efficiency is seriously delayed. Thus, common faults of cold-rolling uncoilers include: abnormal running state of the motor (high temperature of the sliding bearing and large vibration), abnormal rotation of the uncoiler (abnormal tension, current alarm of a frequency converter and abnormal vibration temperature data of a gear box), abnormal rotation of the coiling block (broken sector block and broken four-pyramid wing), incapability of expanding and contracting or opening of the coiling block and the like. Most of the traditional cold rolling uncoilers are operated and maintained through spot inspection, annual inspection and the like, faults can not be monitored and diagnosed in time in the production operation process, normal and reliable operation of the cold rolling unit is seriously affected, and certain potential safety hazards exist.
