Abstract
The invention discloses a method for controlling the plate conveying precision of a bilateral steel shearing plate conveying roller. The method comprises the following steps of: a, inputting parameters and Mu into a calculating module, and calculating an acceleration value of a steel plate during accelerated motion and decelerated motion thereof in a nonslip state, the maximum moving speed of the steel plate and an initial time of the decelerated motion of the steel plate by the calculating module; b, inputting the parameters and Mu into the control module of a roller motor by the calculating module; and c, controlling the roller motor to act according to the parameters and Mu by the control module so as to increase the rotating speed of the conveying roller from zero, and stopping the roller motor at a time point and conveying plates in one step at a moment. By adopting the method disclosed by the invention, accurate control on plate conveying step size of the conveying roller every time is realized, and the whole plate conveying process is under automatic control, so that the working performance is high; and the plate conveying step sizes and rolling friction coefficients Mu adaptive to different steel plate materials are input into the calculating module, so that the plate conveying step sizes of different steel plates can be precisely controlled; and the practicability of the method is good.
