Modular rolling mill having dual speed ratios and unit thereof

Abstract

The invention discloses a modular rolling mill having dual speed ratios and belongs to the field of metallurgy device. The modular rolling mill comprises a mill body, a speed changing box and a motor,wherein the mill body is integrated with two driver columns, the speed changing box provides two speed ratios and is internally provided with an input shaft connected with the motor, a first output shaft, a second output shaft and an intermediate shaft respectively in driven connection with an input shaft, the first output shaft and the second output shaft; the first output shaft and the second output shaft are respectively connected with the two driver columns; the input shaft, the first output shaft and the second output shaft are respectively coupled with large and small idler gears through respectively arranged clutches, and the intermediate shaft is provided with two fixed gears engaged with the two idler gears respectively arranged on the input shaft, the first output shaft and thesecond output shaft in a driving way. The problem can be solved that the speed ratio of the two driver columns modularized singly cannot be adjusted flexibly, and the problems of complicated device structure, high no-load power consumption and the like in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical rolling equipment, and in particular relates to a modular rolling mill with two speed ratios and a unit thereof. Background technique [0002] In the modern wire rod production, the equipment commonly used at present is the high-speed wire rod finishing mill, through the high-speed rolling of the wire rod finishing mill, the products that meet the size requirements can be obtained, and the output of the wire rod can be guaranteed. For small-sized wire rod products, in order to ensure the wire rod output, the rolling speed is even as high as about 110m / s. In the early days, due to the dynamic speed drop of steel bite in the high-speed rolling process of wire rods, it could not be solved, so the wire rod finishing mills currently used are all centralized transmission, that is, 8 to 10 wire rod finishing mills are simultaneously driven by a large motor to achieve a top crossing of 45° In twist...
