High pressure tank manufacturing equipment

Abstract

To provide an apparatus for manufacturing a high-pressure tank capable of suppressing occurrence of a gap between a mouthpiece and inner layer fibers at a portion where the fibers fall into the mouth piece.SOLUTION: An apparatus for manufacturing a high-pressure tank is employed in manufacturing of the high-pressure tank which has a liner and mouthpieces and in which a fiber-reinforced resin layer obtained by impregnating a thermosetting resin on the outside of the liner to thermally cure the thermosetting resin, is arranged. The apparatus comprises: a shaft for supporting the tank being an intermediate product of the high-pressure tank formed by arranging the fiber-reinforced resin layer before thermal curing on the outside of the liner via the mouthpiece; a rotation mechanical unit for rotating the shaft during thermal curing of the tank; and a heating device for heating the tank attached to the shaft during the thermal curing of the tank. When the rotation mechanical unit rotates the tank, the shaft is arranged to be inclined in a gravity vertical direction with respect to a horizontal direction.SELECTED DRAWING: Figure 1

Claims

[Claim 1] A high-pressure tank manufacturing apparatus used for manufacturing a high-pressure tank having a liner and a mouthpiece, the high-pressure tank having a fiber-reinforced resin layer impregnated with a thermosetting resin and thermoset on the outside of the liner, a shaft that supports, via the nozzle, a tank that is an intermediate product of the high-pressure tank in which the fiber reinforced resin layer before thermal curing is disposed on the outside of the liner; a rotation mechanism for rotating the shaft during thermal curing of the tank; a heating device for heating the tank attached to the shaft during thermal curing of the tank; Equipped with The nozzles are provided on both ends of the tank, The axial length of the shaft is 3 to 4 times the overall length of the tank, the tank is disposed on the shaft such that, when the tank is rotated by the rotation mechanism, the height positions of the nozzles at both ends are lower in the direction of gravity than the height positions of both ends of the shaft by 5% or more of the axial length of the shaft.
