POLISHING MEDIA AUTOMATIC EJECTING MOTION APPARATUS OF AN AIR SAND-BLAST MACHINE CAPABLE OF SIMULTANEOUSLY CUTTING A CUTTING TARGET INTO SEVERAL PIECES

摘要

PURPOSE: The polishing media automatic ejecting motion apparatus of an air sand-blast machine is provided to minimize the splattering phenomenon of the polishing media by forming a minimum hole at the wall of a chamber. CONSTITUTION: Polishing media is ejected through a plurality of nozzles(16a) in order to shape a cutting target. The nozzles are arranged on a nozzle mounted plate(25a) which is installed at the inside of a chamber(14). A polishing media automatic ejecting motion apparatus includes an opening(31), X-axis and Y-axis rails(35, 36), and a first ejecting unit(32). The opening is longitudinally formed at the rear side of the chamber. The rails are installed at a support(34) which is installed at the lower side of the opening. The first ejecting unit is installed at a slide on the Y-axis rail and is in connection with a rod(33). The rod moves along the shape of a product according to the drive of X-axis and Y-axis motors.
