Abstract
Disclosed is an ultra-thin strap combined forming rolling mill with the different speed ratios capable of being adjusted online and continuously. The ultra-thin strap combined forming rolling mill comprises a rolling mill master control part and a rolling mill mechanical part. A rolling mill control system human-computer interface is arranged in a master control computer. Input fields and output fields for speed setting of an upper working roller and a lower working roller, and an input field and an output field for adjustment step size setting of the different speed ratios are arranged on the human-computer interface. The master control computer is connected with an operation platform through a programmable logic controller (PLC). A rolling forward starting switch, a rolling backward starting switch and a different speed ratio adjusting switch are arranged on the operation platform. The different speed ratios can be increased or decreased by a different speed ratio adjustment step size online through the different speed ratio adjusting switch. When asymmetrical rolling of an ultra-thin strap is conducted through the ultra-thin strap combined forming rolling mill, the different speed ratios can be arranged to be infinitely variable and can be set to be an arbitrary value in theory. Due to the fact that the limit of the minimum rolling thickness of the synchronous rolling is overcome by the asymmetrical rolling and the thinness rolling capacity is stronger, the selection range of the diameter of the working rollers of the ultra-thin strap combined forming rolling mill can be broadened, accordingly, the occurrence of torsional vibration phenomena of the rollers is effectively reduced, and the surface quality of the ultra-thin strap is improved.
