Drawing cutting device for mechanical automation specialty

The invention belongs to the technical field of cutting, and particularly relates to a drawing cutting device for mechanical automation specialty. The device comprises a cutting table, wherein supporting rods are fixedly connected to the four corners of the upper end face of the cutting table, a mounting box is fixedly connected to the upper end faces of the four supporting rods, and a mounting plate is fixedly connected to the back of the inner wall of the mounting box. A cutter holder at the bottom performs the same right lower movement, so that the cutter is driven to move downwards and move rightwards at the same time, a drawing at the upper end of the cutting table is obliquely cut, an air cylinder shrinks after cutting is completed, and the cutter can be driven to retract, so that compared with vertical tangent cutting, the flatness of the cutting face is improved, more labor is saved, and the drawing cutting effect is improved; and the device solves the problems that according to an existing drawing cu
