Disassembling method of mandrel used for manufacturing composite material structure and disassembling apparatus of mandrel |
摘要 |
The present invention provides a technique which can disassemble a mandrel having a substantially cylindrical shape and being dividable into a plurality of segments, easily and efficiently. The disassembling method comprises, in the mandrel adhesively attached with a composite material structure on an outer peripheral surface thereof, a rotation step of rotating the pair of support rings along with the mandrel to position a segment which is a detached target to an uppermost portion; and a segment detaching step of detaching the segment which is the detached target positioned at the uppermost portion, from the pair of support rings; wherein in the segment detaching step, the segment which is the detached target is moved in a vertically downward direction to a position inside of the mandrel, between the pair of support rings, and is carried out from between the pair of support rings. |

1. A disassembling method of a mandrel, which disassembles the mandrel including a plurality of segments assembled in a tubular shape, into individual segments, the plurality of segments having a substantially rectangular shape and being parts into which the mandrel is divided along a center axis direction, wherein the plurality of segments include a first segment and a second segment which are different in shape, and an obverse surface of the second segment which is a part of an outer peripheral surface of the mandrel, has a greater area than an obverse surface of the first segment which is a part of the outer peripheral surface of the mandrel;
the mandrel being in a state in which the segments are joined together between a pair of support rings facing each other, the segments are each fastened to the support rings to form the tubular shape, and the mandrel is adhesively attached with a composite material structure on an outer peripheral surface thereof; the disassembling method comprising: a rotation step of rotating the pair of support rings along with the mandrel to position a segment which is a detached target to an uppermost portion; and a segment detaching step of detaching the segment which is the detached target positioned at the uppermost portion, from the pair of support rings; wherein in the segment detaching step, the segment which is the detached target is moved in a vertically downward direction to a position inside of the mandrel, between the pair of support rings, and is carried out from between the pair of support rings, and wherein the segment detaching step includes a first segment detaching step of detaching the first segment, and a second segment detaching step of detaching the second segment, and the first segment detaching step is performed before the second segment detaching step. |
