Active precision four-roll mill

Abstract

The invention discloses an active precision four-roll mill, which comprises a stand (1), a motor (2), a gear box (3), a mounting plate (4) and a mill main body, wherein the mill main body comprises a mounting head (11), fork heads (12), driving rolls (15) and driven rolls (16); the mounting head (11) is fixedly arranged on the mounting plate (4); the upper side, the lower side, the left side and the right side of the mounting head (11) are rotatablely connected with the fork heads (12) respectively; the driving rolls (15) are rotatablely arranged in the upper fork head and the lower fork head; gears (20) are arranged inside the driving rolls (15); the driven rolls (16) are rotatablely arranged in the left fork head and the right fork head; and the fork heads are connected with the mounting plate (4) through springs (22). The active precision four-roll mill has the beneficial effects that: flat mill and vertical mill are on the same section; a produced irregularly-shaped steel wire has an ideal edge; and meanwhile, one mill can be used for realizing the functions of various mills.

Description

technical field [0001] The invention relates to a rolling mill, in particular to an active precision four-high rolling mill. Background technique [0002] Rolling is defined as a technique for shaping materials. Produced with a cylindrical tool called a "roller," the energy for forming comes from traction pulling the material or powering the roll. The simplest rolling mill technology uses two parallel rolls on a shaft, and the material fed can be round or preformed. In most cases, it is used to produce flat wire. If you need to produce shaped products, you can open holes on the roll. Several two-high rolling mills are often assembled into a continuous flattening line. At least two flat rolling and one vertical rolling. Those flat wires that require high width and thickness precision need to use such a rolling mill production line. However, the flat rolling and vertical rolling of the existing rolling mills are not on the same section, and the edge of the steel wire produc...

AI Technical Summary

Problems solved by technology

At least two flat rolling and one vertical rolling. Those flat wires that require high width and thickness accuracy need to use such a rolling mill production line. However, the flat rolling and vertical rolling of the existing rolling mills are not on the same section, and the edges of the steel wire produced are often up to Less than required precision
