Abstract

A large-scale axle intelligent cross wedge rolling mill for rail transit includes a main transmission device, a memorial arch unit, two worm-gear pressing devices, a roll assembly and two guide devices. The separation sleeves are engaged with the upper slide shaft and the lower slide shaft, respectively. Two lower shaft necks are detachably connected with the left end surface and the right end surface of the lower roller, respectively; two upper shaft necks are detachably connected with the left end surface and the right end surface of the upper roller, respectively, so that the quick disconnection of the upper and lower rollers with the upper and lower shaft necks is able to be achieved, so as to quickly operate and install the roll to meet the requirement of quick mold replacement, thus improving the flexibility of rolling.
