Title:
QUICK ROLL CHANGING LEVELING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/012762
Kind Code:
A1
Abstract:
A quick roll changing leveling machine, comprising an upper cross beam (2), an upper roll system pressing mechanism, an anti-backlash mechanism, a 1# roll system capable of changing rolls with a 2# roll system, upper and lower roll system positioning and locking mechanisms, a lower base (7), a supporting roll adjusting mechanism, a roll system moving-out mechanism, a transmission component, and a gear box. One leveling main machine corresponds to two sets of roll systems having different leveling roll diameters, and the two sets of roll systems are rapidly interchanged. The roll systems are mounted on upper and lower cutting blocks (3, 6), and the upper and lower cutting blocks are respectively positioned and locked by using upper and lower locking oil cylinders (8, 14). Automatic centering can be achieved when the two sets of roll systems are interchanged by adopting a spherical gear coupling (38). A hydraulic motor (23) drives a rack (22) of a gear (24) to drive the roll system to be quickly and stably moved out. The processing capacity of the leveling machine is increased, production is not delayed during the maintenance of a set of roll system, and the labor intensity of a maintenance worker of the leveling machine is greatly reduced.
