Field of the Invention [0001] The present invention relates to an apparatus for manufacturing a circularly-shaped preform for a composite material, and more particularly, to a preform manufactured by braiding a composite material room, It is possible to provide a preform having a ring shape and to provide a driving part and a support part so that the ring frame can be easily and easily rotated and supported and that the ring frame is installed in the braiding device, To an apparatus for producing a circular-shaped preform for a composite material, which is capable of forming a preform with a stable shape by constituting an inlet or a disassembling and assembling unit.

Description

TECHNICAL FIELD [0001] The present invention relates to a circular braiding preform manufacturing apparatus for a composite material,

In the present invention, in the braiding of various materials, various preforms are wound and the frame to be braided is used as a ring, and the preform itself having a braid is formed into a circular shape, thereby preventing a problem caused by a shape change in a linear preform And a manufacturing apparatus for easily attaching and detaching a ring frame.

In recent years, it has been common to manufacture a plurality of mixed fiber yarns by braiding (braiding) fabrics when producing various mixed fibers. That is, in the case of the mixed fibers produced by the braiding process, the rigidity is excellent, compared with the case where the various fibers are laminated in layers.

In the configuration of the braiding device, a plurality of fiber room rolls wound with fibers to be subjected to a braiding operation are arranged in a circular shape on the rim of the main plate, And the wind-up frame is provided so as to be moved in one direction at a predetermined speed in the forward and backward directions from the center of the rim of the main plate.

As a result, the plurality of fiber room rolls are rotated individually, and the main plate itself, in which the plurality of fiber room rolls are provided, is also rotated so that the plurality of fiber yarns are crossed and braided intricately to the outer periphery of the winder frame.

The straight cylindrical preform made by completing the braiding process will be used according to the application in the place of application through a separate fiber treatment (ex. Resin quenching).

However, in the conventional braiding device as described above, since the frame in which the fiber yarn is wound has only a linear shape, it is possible to produce only the linear preform. When the linear preform thus completed is bent or bent according to various applications, The structure of the portion where the broken tissue is broken or bent is not made uniform, so that the stiffness is lowered and the load bearing capacity is lowered.

The support portion 40 is also mounted on the operation portion 31, So that the ring frame 20 can be horizontally installed on the floor through the braiding device 10 in a state where the ring frame 20 is separated from the ground surface together with the above- .

That is, a plurality of or a plurality of support portions 40 are locally installed in the remaining portion of the ring frame 20 where the operation portion 31 is not provided.

The support portion 40 for this purpose includes a first guide portion 41 and a second guide portion 42.

The first guide portion 41 is a roller that is rotatably installed on the upper surface of the mount table 40a and is in contact with the outer periphery of the ring frame 20 rotated by the driving portion 30 described above, 20) and guiding the rotation direction.

The second guide portion 42 is installed on the mount 40a so as to be positioned outside a plurality of the first guide portions 41. The second guide portion 42 is provided on the upper surface of the ring frame 20, And the upper and lower rollers 37 and 38 are in contact with each other so that the ring frame 20 is spaced apart from the upper surface of the cradle 40a so as to be smoothly rotated.

In addition, in the case of the above-described operating portion 31 and supporting portion 40 described in the present invention, in the present invention, one operating portion 31 and two supporting portions 40 are provided to support the ring frame 20 The spacing distance (or installation angle) between the three actuating portions 31 and the supporting portion 40 is constantly maintained for stable positioning and rotation of the ring frame 20 rotated at this time Even when the number of the supporting portions 40 is increased by the user, the distance and distance between the actuating portion 31 and the plurality of supporting portions 40 must be changed accordingly to maintain the same spacing. something to do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
