Improved four-roll finishing mill

Abstract

The invention relates to the technical field of metallurgical machinery, in particular to an improved four-roll finishing mill. The improved four-roll finishing mill comprises a base and a rack; a motor is connected with a compound gear box through a coupler, two universal joint shafts are connected to the interior of the compound gear box, two parallel supporting rolls are connected to the otherends of the universal joint shafts, two working rolls are arranged between the two supporting rolls, and a feeding pressing plate is arranged between the working rolls; a pressing device is arranged on the upper portion of the rack and comprises a pressing motor, a worm gear and a worm; the worm is fixed to the rack through a nut, a rotary encoder is connected to the worm, and the output end of the rotary encoder is connected to a control system; and an adjustable rod is arranged on the lower portion of the rack and is overall in an L shape, and a rotating wheel is fixed to the bottom of the adjustable rod.

Description

technical field [0001] The invention relates to the technical field of metallurgical machinery, in particular to an improved four-high finish rolling mill. Background technique [0002] Gold foil, silver foil, and copper foil are widely used, and are usually obtained by multi-pass rolling on a four-roll rolling mill. However, the rolling limit thickness of the traditional four-roll rolling mill can only reach 0.02mm, which is no longer enough to meet the needs. In order to achieve a rolling thickness of 0.005 mm or even thinner, it is currently necessary to use multi-roll rolling mills such as 12 rolls and 20 rolls for rolling, which leads to high manufacturing costs and serious waste of resources and capabilities. Contents of the invention [0003] The object of the present invention is to provide a four-roll finishing mill capable of producing a thickness of 0.005mm, and the four-roll finishing mill is equipped with a pressure sensor, which can control the pressing force...
