Problems solved by technology

[0004] The control circuit of the above-mentioned ironing roller device has the following disadvantages: 1. The control of the ironing force is inaccurate and cannot meet the production requirements; 2. Due to factors such as high compressibility, low viscosity, and low rigidity of the gas, the control accuracy is low and the response speed is low. slow
Therefore, the existing control loop of the ironing roller unit is difficult to meet the requirements of modern high-capacity units

Abstract

The invention discloses a hydraulic control loop for an ironing roller device, which comprises first and second hydraulic cylinders for driving an ironing roller, first and second pressure sensors arranged on the first and second hydraulic cylinders respectively, and a first servo valve, a second servo valve and an electromagnetic reversal valve which are connected among the first and second hydraulic cylinders and a hydraulic oil source by pipelines. The hydraulic control loop for the ironing roller device can accurately control the ironing pressure of the ironing roller, has high control accuracy, fast response speed, remarkable strip ironing effect and better quality, greatly increases the speed of a unit and increases the finished product ratio of the strip.

Description

technical field [0001] The invention belongs to the technical field of control of a coiler ironing device of an aluminum strip and foil rolling mill and a coiling unit, and in particular relates to a hydraulic control circuit of an ironing roller device. Background technique [0002] In the non-ferrous metal processing industry, with the increase of the operating speed of the aluminum strip and foil rolling mill and the coiling unit, during the coiling process of the aluminum strip and foil, due to air ingress, the coil will bulge, shrink and uncoil, and the strip will be seriously damaged. The shape of the plate increases the production loss and the difficulty of processing the next process. In order to avoid the above phenomena, the common practice is to limit the rolling speed of the strip, and as a result, the production capacity of the rolling mill cannot be fully utilized. In order to solve the above problems, the key factors are found out in combination with the proc...
