Multi-roll Xingyu type multi-variable combined rolling mill and its principle

Abstract

A multi-roll planetary changeable combined mill comprises a roll complex (30), an upper rack (10), a lower rack (20), transmission devices (40, 50) and a screw-down device (60). n roll complexes with left and right supports are installed on the upper and the lower racks, the n roll complexes being radially and uniformly distributed with the cross section of a rolled piece as a center. The mill structure is reliable and reasonable, and has simple parts; a great number of rolls can synchronously and centripetally rotate, can be manually or automatically screwed down, and are convenient to change and guarantee reliable transmission; many forms of continuous rolling groups can also be formed; and the multi-roll planetary changeable combined mill can be used for rolling extremely large or small bars, pipes, profiled bars or wires.

Description

technical field [0001] The present invention relates to a kind of metal calendering machine commonly known as a rolling mill, in particular to a kind of rolling machine with a plurality of rolls centered along the cross-section of the rolled piece, radially and uniformly distributed in a 360° cylinder space, and the rolls can be changed according to the shape of the rolled piece The shape, quantity and combination method are used for rolling bars, wires, pipes and profiles, and can be used for room temperature cold rolling, warm rolling and hot rolling multi-roll multi-purpose Xingyu multi-variable combined rolling mill. Background technique [0002] The metal rolling process and rolling equipment, especially the rolling mill, have been greatly developed after more than two hundred years of evolution; the current annual output of steel in China is close to 700 million tons, and the amount of various non-ferrous metals and alloys is even greater , more than 90% of these metal...

AI Technical Summary

Problems solved by technology

Although these two rolling mills can greatly reduce the width of the section during the rolling process, the amount of width cannot be ignored, and the above-mentioned rolling mills are all closed, and the method of synchronous centripetal pressing of each roll is used for four A roll is already relatively complex, if the number of rolls increases, the structure will be very complicated
