Problems solved by technology

In the above automatic sizing control model, the value of K directly affects the dynamic response of the system. If the value of K is too large, the transient response of the system will change greatly, which will easily cause system instability; if the value of K is too small, the change of transient response will be small, and the response long time
Therefore, the change of K value makes the system prone to steady-state error, which will greatly affect the sizing accuracy of the steel plate

Abstract

The invention provides a steel plate shear gauge. The steel plate shear gauge comprises a gauging trolley, a trolley driving motor and a conveying mechanism used for conveying steel plates, wherein two racks are arranged above the conveying mechanism in parallel in the steel plate conveying direction, a gear used for traveling is arranged at the lower end of the gauging trolley, the gear is meshed with the racks and is installed on an output shaft of the trolley driving motor through a speed reducer, an encoder is installed on the output shaft of the trolley driving motor which is connected with a frequency converter, and the frequency converter and the encoder are connected to a controller. The steel plate shear gauge further comprises a gauging baffle used for positioning the steel plates, wherein the gauging baffle is fixed to the gauging trolley through a lifting mechanism. The invention further discloses a gauging method of the steel plate shear gauge. Segmented control over the rotating speed of the trolley driving motor is achieved through segmented control over the output frequency of the frequency converter. According to the steel plate shear gauge and the gauging method thereof, the gauging precision of the shear gauge is improved greatly, and practicality is high.

Description

technical field [0001] The invention relates to a sizing machine and a sizing method, in particular to a steel plate sizing machine and its sizing method. Background technique [0002] As we all know, the sizing accuracy is the key factor affecting the yield and scrap rate, and the sizing device is one of the keys affecting the investment cost of the steel mill. The sizing machine is a commonly used sizing device. The existing sizing machine mainly drives the driving wheel or rack and pinion of the sizing trolley directly through the motor to realize the horizontal movement of the sizing trolley on the track. Fix the fixed-to-length trolley to the track on both sides of the fixed-to-length trolley to prevent the trolley from moving. This method of preventing the movement of the sizing trolley is cumbersome to operate and affects the sizing efficiency of the sizing machine; and the above-mentioned locating pins are not easy to take out when they are crushed, which is not on...
