    Abstract: A single-side tower-type roller system based asynchronous rolling mill for rolling an ultra-thin composite strip and a hydraulic system therefor are provided. The mill includes a machine frame and reel assemblies. An upper roller system assembly and a lower roller system assembly are arranged in the machine frame. A down-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the upper roller system assembly and the lower roller system assembly. A support roller balance assembly is arranged on the machine frame and used to support and balance the upper roller system assembly. The lower roller system assembly includes right and left working rollers. The right working roller is a plain roller. The left working roller is a patterned roller. A left-pressing assembly is arranged on the machine frame and used to adjust a roll gap between the right and left working rollers.

    Abstract: A rigid-flexible coupling-driven robot for removing oxide scales on super large shaft forgings online includes a heavy-duty manipulator main body, four walking systems, a movable arm lifting system, a clamping system, a power system, two oxide scale removal systems and a visual identification system. The two oxide scale removal systems are respectively installed on the two trapezoidal plates of the clamping system. Each of the two oxide scale removal systems adopts rigid-flexible coupling drive technology, that is, the rigid drive of the overhead hydraulic cylinder, cable-stayed hydraulic cylinder, the long stroke scissor retractable bracket and the rack and pinion device is combined with the flexible drive of the wire rope, so that the retraction and the angle tilt of the parallelogram end removal device are realized, which makes the oxide scale removal more flexible and efficient, thus greatly improving the product quality of large forgings.
