CUTTING APPARATUS OF A PIPE

摘要

The present invention relates to a round bar cutting apparatus and, more specifically, to a round bar cutting apparatus capable of improving work efficiency by conveniently cutting a round bar using a material cutting unit with an upper and a lower cutter, wherein the upper and the lower cutter between which the round bar with a length adjusted into a certain length is supplied to be cut are capable of continuously cutting the round bar when alternately operated up and down. According to the present invention for the above effect, a round bar cutting apparatus capable of continuously cutting a supplied round bar (S) comprises: a main body (100) formed into a frame having a housing space (140) therein, and having a sub frame (120) receiving the round bar (S) and coupled to penetrate one side thereof; and a material cutting unit (200) having a power transmission unit (210), a link (220), a slide member (230), an upper cutter (241), and a lower cutter (251), wherein the upper cutter (241) coupled to the bottom of the slide member (230) and the lower cutter (251) coupled to one side of the sub frame (120) are capable of cutting the supplied round bar (S) by being adjacently and alternately operated up and down when the slide member (230) is allowed to linearly reciprocate by an eccentric rotation due to a mutual coupling between the power transmission unit (210) and the link (220). The upper cutter (241) and the lower cutter (251) having U-shaped processed grooves (260) and coupled to an upper holder (240) fixed to the bottom of the slide member (230) and a lower holder (250) fixed to the one side of the sub frame (120) are capable of being replaced respectively.
