Abstract

PURPOSE:To eliminate the generation of uneven thickness of a molding by using a cylindrical fiber by a method in which a turnable annular tube to press a fiber coming out of a housing cylinder onto the inner surface of cylindrical molds is provided on a resin liquid supply tube side in such a way as to allow the fiber to move smoothly and exactly. CONSTITUTION:Under the condition that a supplyer 5 is deeply inserted into a cylindrical mold 1, the tip of a fiber 7 is fixed to the inner surface of the cylindrical mold 1 from an end face tool 4 side. While turning the mold 1 and the supplyer 5 integrally around the horizontal axis 3, the supplyer 5 is drawn out while supplying a resin liquid 6. The fiber 7 is then drawn out of a fiber housing cylinder 12 and pressed on the inner surface of the mold 1 while being extended by a tube 13. In this case, the tube 13 turns around the axis 15 without any sliding contact. The resin liquid is then supplied onto the fiber 7 pressed from a resin liquid spreader 11 and centrifugally molded. The fiber 7 can be exactly transferred without forming lapped portion because the cylindrical material can be used in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a centrifugal molding apparatus for manufacturing resin tubes containing fibers (reinforced fiber cloth).

Conventional centrifugal molding equipment is a tI-type machine in which fibers on a shaft body inserted into a cylindrical mold are transferred onto the inner circumferential surface of the cylindrical mold, and then a resin liquid is supplied into the cylindrical mold for centrifugal molding. there were. According to such conventional groove formation, the fiber cannot be smoothly transferred, and the fiber is often wound in a wavy manner on the inner circumferential surface of the cylinder.

Also, since the starting and ending ends of the fiber are polymerized, j! When manufacturing resin pipes with a thickness of ¥3, the overlapping part tends to have uneven thickness.

The present invention aims to solve the above problems.

That is, the present invention has a cylindrical shape that is rotatable around a horizontal axis, and a supply device that supplies resin liquid and fibers into this cylindrical shape, and the supply device is located on the horizontal axis. A resin liquid supply pipe, a resin liquid dispersion tool that communicates with the tip of the resin liquid supply pipe and is close to the cylindrical inner peripheral surface, a fiber storage cylinder that fits onto the resin liquid supply pipe, and a fiber storage cylinder that is attached to the resin liquid supply pipe. It consists of an annular tube hub body that is provided between the outlet and the resin liquid dispersion tool and presses the guided fibers against the cylindrical inner circumferential surface, and allows the A tube body to rotate around the tube axis. The present invention provides a centrifugal forming device that is attached to the liquid supply pipe side. According to this configuration, when the fiber is transferred from the fiber storage tube onto the cylindrical inner circumferential surface, the fiber is transferred through the tube body. The fiber can be pressed against the inner peripheral surface of the cylindrical shape, so the fiber can be pressed smoothly and reliably.Furthermore, the fiber can be used in a cylindrical shape in advance, so no overlapping parts occur. , it is possible to completely eliminate the uneven thickness phenomenon even in thin-walled resin pipes.

Hereinafter, one embodiment of the present invention will be described based on the drawings. (
The frame is cylindrical, supported by multiple wheels (2) and centered horizontally (

The supply device includes a resin liquid supply pipe (8) located on the horizontal axis (3) and a pump (
Resin liquid dispersion tool <11 which communicates with the tip of the liquid supply pipe (8) and is close to the inner peripheral surface of the cylinder (1). ) and the tree 11t

According to the centrifugal molding apparatus of the present invention as described above, the fibers are not transferred from the fiber storage cylinder to the entire inner circumferential surface of the cylindrical shape, and at the same time, the fibers are transferred to the inner circumferential surface of the cylindrical shape through the tube body. Therefore, the fiber can be transferred smoothly and reliably. Further, since the fiber can be used in a cylindrical shape in advance, and therefore no overlapping portion is generated, uneven thickness can be avoided even in a 11V pipe.
