| description | The invention discloses an air cylinder protection method for a tail clamping brake device, which comprises the following steps: after a bar is cut off by a double-length shear for shearing the bar, the bar is completely driven by a brake roller at the moment, and the movement speed of the bar is equal to the linear speed of the brake roller; the linear speed of a brake roller is reduced by controlling the motor speed of the tail clamping brake device so as to reduce the bar movement speed, and the bar tail movement position is obtained through calculation and tracking according to the feedback speed of the bar movement speed; and when the movement speed of the bar on the brake roller line is equal to the release speed and the movement position of the tail of the bar is in front of the brake roller, the brake roller is opened, so that the brake roller is opened to release the bar when the tail of the bar leaves the brake roller, and the secondary closing action of the brake roller is eliminated.
