ABSTRACT:
An automatic picture tube cutting machine is provided. The machine includes a transporting mechanism for transporting a tray carrying a picture tube into a moving-up-and-down base, which automatically adjusts the vertical position of the picture tube based upon its size. The machine also includes a positioning and cutting device wherein a plurality of clamp units cooperatively set tungsten heating filaments in contact with the picture tube to circumscribe that picture tube at a preset cutting height. Upon heating via the tungsten heating filaments and subsequent cool water quenching, the picture tube is broken at its circumscribed portion into separated front and rear stages.
