All-electric roll changing system of cold rolling mill and roll changing method utilizing same

Abstract

The invention provides an all-electric roll changing system of a cold rolling mill and a roll changing method utilizing the same. The system comprises a travelling vehicle, a tractor, a clamping device, a transverse moving vehicle and a rope pulling emergency stop switch, wherein the travelling vehicle, the tractor, the clamping device and the transverse moving vehicle are each provided with an independent driving source which is a motor, an encoder is installed at the tail of each motor, a plurality of position switches are arranged in a roll changing area of the cold rolling mill, the position switches are position switches corresponding to limiting positions of the travelling vehicle, the tractor and the transverse moving vehicle, and the position switch installed at the output end of the motor of the clamping device, and all the motors, all the encoders, all the position switches, and the rope pulling emergency switch are connected to PLC. The roll changing system uses the encodersand the position switches to cleanly and efficiently complete all actions required by roll changing of an aluminum rolling mill, further uses the encoders and the position switches to orderly and accurately guarantee in-place and cooperation of all the roll changing actions, full-automatic roll changing system is realized, and the numerous problems in actual production of a traditional roll changing system are thoroughly solved.

Description

technical field [0001] The invention belongs to the field of roll changing of aluminum rolling mills, and in particular relates to an all-electric roll changing system of a cold rolling mill and a roll changing method thereof. Background technique [0002] The role of aluminum products in the development of the national economy is becoming more and more prominent, and aluminum strip products are widely and deeply used in many fields such as packaging, automobiles, military industry and microelectronics. Due to the soft nature of the aluminum material, its production process is very different from traditional ferrous metals, especially the surface of the aluminum strip is extremely sensitive to oil stains. [0003] At present, the aluminum strip is produced by irreversible rolling process. Even a small amount of oil on the surface of the roll will be printed on the surface of the strip due to the huge rolling pressure, which will greatly reduce the value of the product and ev...
