Title:
ORBITAL CUTTING APPARATUS CAPABLE OF FREELY AND SELECTIVELY CONTROLLING PLURALITY OF CUTTING TOOLS WITHIN ROTATING BODY BY USING ROTATIONAL SPEED RATIO
Document Type and Number:
WIPO Patent Application WO/2016/060420
Kind Code:
A1
Abstract:
Disclosed is an orbital cutting apparatus capable of freely and selectively controlling forward and backward movements to/from a plurality of cutting tools, allowing the cutting tools to move forward and backward and move in an axial direction of a material being cut so as to enable cutting, chamfering and machining of various shapes, and capable of simultaneously carrying out cutting and chamfering operations for a pipe material or a heavy pipe having a thickness of several tens of mm or more. The orbital cutting apparatus, according to the present invention, comprises: a spindle rotating unit coupled to one surface of a main body unit so as to rotate (C axis); a plurality of tool units coupled to reciprocate (X axis) toward the center part of the spindle rotating unit on the front surface of the spindle rotating unit, thereby cutting the clamped material in an orbital manner; a relative movement unit coupled to the main body unit on the opposite side of the spindle rotating unit to enable rotation by synchronizing with the spindle rotating unit, and transferring power to the plurality of tool units so as to allow the tool units to reciprocate; a connection gear formed at the ends of driving shafts of the tool units so as to selectively engage with the relative movement unit, such that the power of the relative movement unit is received; an operation unit for allowing the selected connection gear to engage with or be spaced from the relative movement unit; and a control unit for controlling the movements of the spindle rotating unit and the relative movement unit.
