Stretching-bending straightening machine

Abstract

The invention relates to a stretching-bending straightening machine which is characterized in that a front tension mechanism and a back tension mechanism are respectively arranged at front and back sides of a rolling mill. The front tension mechanism comprises a first roller and a second roller, wherein the first roller and the second roller are parallel in an axial direction and are arranged from left to right in a manner that one is high and the other one is low; and a gap is reserved between vertical projections of the first roller and the second roller. One end of a rolling shaft of the first roller and one end of the rolling shaft of the second roller are provided with first power mechanisms. The back tension mechanism comprises a third roller and a fourth roller, wherein the third roller and the fourth roller are parallel to the axial direction and are arranged from left to right in a manner that one is low and the other one is high; and a gap is reversed between the vertical projections of the third roller and the fourth roller. One end of the rolling shaft of the third roller and one end of the rolling shaft of the fourth roller are connected with the first power mechanisms. By utilizing the stretching-bending straightening machine to roll metal strips, defects of edge waves, middle waves, warping and the like can be eliminated, so that the quality of the strip is improved. The stretching-bending straightening machine is suitable for rolling the metal strip.

Description

[0001] technical field [0002] The invention relates to a rolling mill. Specifically, it is a stretching and bending straightening machine with the functions of tension, finishing, bending and straightening, and is suitable for rolling metal strips. Background technique [0003] It is well known in the field of rolling mill manufacturing and application that currently the only equipment used for rolling metal strips is a rolling mill and a tempering mill. After rolling the metal strip with a rolling mill and a tempering mill, the metal strip will have side waves and middle waves. Defects such as warping and warping make the quality of the processed strip poor. Contents of the invention [0004] The problem to be solved by the present invention is to provide a stretch bending straightening machine. Rolling metal strips using this stretching bending straightening machine can eliminate defects such as edge waves, middle waves and warping, and improve the quality of the str...
