The invention discloses a
processing mechanism control method and device of a blanking
machine, and relates to the technical field of
automation control, the method comprises the following steps: in the feeding process, detecting the position of the front end face of a profile through a
laser sensor, and calculating the end
cutting length according to the current position of a sliding table; the sliding table is controlled to feed materials to the position of a saw blade for end
cutting; the sliding table is controlled to move backwards by the distance of the
cut-off size; the clamp is controlled to clamp the profile to move forwards by the distance of the
cut-off size for
cut-off; when the
tail part of the section bar is left, detecting whether the section bar is separated from the material clamping identification roller; if the section bar is separated from the material clamping identification roller, the sliding table is controlled to move forwards at a
low speed until the
tail end of the section bar touches the material clamping identification roller; the residual length of the
tailings is calculated according to the position of the sliding table, if the residual length is larger than the minimum clamping length,
cutting is conducted again, and otherwise, the
tailings are ejected out; and the discharging separation tray is controlled to swing leftwards or rightwards, and finished products and waste materials are separated. Automatic classification of finished products and waste materials is achieved, and the production efficiency is improved.
