Problems solved by technology

In the case of ensuring that the set width accuracy of the disc shears meets the standard, there is currently no ready-made experience that can be used for reference on how to achieve the requirements for the width accuracy of the sheared strip through the roll gap adjustment of the production line, stable tension shearing and CPC related control

Embodiment

[0047] like figure 1 , 2 Shown, control method of the present invention comprises the following steps:

[0048] A set of roll gap adjustment devices are respectively placed on both sides of the main pinch roll of the production line, through the (102) roll gap adjustment screw, the linkage control (103) roll gap lower slope control device drives the (101) upper slope control device , wherein (104) is a frame integrated with the main pinch roller. (202) roll gap control disc drives (102) roll gap adjustment screw linkage control (103) roll gap lower slope control device drives (204) main pinch roller lower roll, (101) upper slope and (201) roller machine The frame is connected to drive (205) the upper roll of the main pinch roller. Because the two-side roll gap is adjusted through the (102) roll-gap adjustment screw linkage, so as to reduce the error during the adjustment of the two-side roll gap, improve the roll gap control accuracy, and ensure the tension when the product...

Abstract

A control method for improving the precision of strip shear width, characterized in that the method comprises the following steps: a. adopting a set of integral adjustment mechanism to improve the control precision of the main pinch roller gap; b. adopting a pair of Stabilizing rollers for stable shearing to control the tension of the strip steel in the working area of ​​the disc shears. c. The CPC centering control system adopts two control modes to deal with strip shearing in normal operation and subcontracting or strip tailing pairing respectively. Central control, that is, do not deal with high-speed strip centering and strip centering control during strip threading. The invention ensures the stability of the strip steel when the unit is running at high speed through the main pinch roller and the stabilizing roller, so as to ensure the width accuracy of the disc shear.

Description

technical field [0001] The present invention relates to a processing method for oriented silicon steel, in particular to a finishing unit for oriented silicon steel and a control method for improving the precision of strip steel shear width. During the shearing process, it meets the high-precision requirements for the width of the sheared strip. Background technique [0002] At present, the oriented silicon steel finishing line uses a tape measure to measure the width of the finished product. The width accuracy can only be 0.1mm of the measurement accuracy of the tape measure. As oriented silicon steel users have higher requirements for product quality, some users hope that the width precision of finished products will be increased to 0-0.2mm. The width accuracy of ordinary oriented silicon steel products only needs to be guaranteed to be 0-1mm. This requires not only the setting width accuracy of the disc shears to be increased to 0.01mm, but also the measured width of t...
