The cross-sectional shape of the fiber perforation of the present invention is one of circular, rectangular or polygonal.
By the design, spiral composite materials with different cross sections can be manufactured by replacing the shaping blocks 221 perforated by different fibers.
The working process of the composite material spiral member forming system comprises the following steps:
connecting the fiber bundle with a traction rope, pulling the traction rope by manpower or a mechanical arm, collecting the fiber bundle through a fiber bundling device 7, finishing gum dipping in a fiber gum dipping device 3, finishing collecting preforming (the cross section shape of the fiber is not formed at the moment) in a preforming assembly for 2 seconds, then leading the traction rope and the preformed fiber bundle to enter a molding groove 212 and a molding block 221 in the core mold 21 under the driving of the manpower or the mechanical arm, fixedly connecting a traction rope penetrating-out replacement port 213 with a traction rope fixing ring 44, starting a heating plate in the core mold, wherein the temperature of the heating plate is controlled by a temperature-raising program, and the setting of the temperature-raising program is determined by resin glue solution impregnated by the fiber bundle;
the rotating motor is started, the rotating motor drives the gear 54 and the toothed ring 53 to rotate in a meshed manner, the toothed ring 53 drives the rotating circular ring 52 to rotate in the arc-shaped groove 511, the rotating circular ring 52 drives the shaping block 221 to spirally advance in the shaping groove 212 of the spiral groove, and the shaping block 221 and the rotating circular ring 52 are linked through the connecting piece and the connecting rod 222, so that the rotating circular ring 52 rotates around the core mold 21 and advances along the length direction of the core mold 21 in the spiral advancing process of the shaping block 221. Thus, the direction of movement of the rotary ring 52 and the molding block 221 can be changed by changing the forward rotation or reverse rotation of the rotary motor, and the fiber bundles impregnated with the resin glue solution are molded and cured (the cross-sectional shape of the fibers is molded) during the running process of the molding block 221 from one end of the core mold 21 to the other end of the core mold 21 along the spiral groove;
the rotary motor is turned off, the driving motor is started, the driving motor drives the turntable 43 to rotate along the spiral direction of the spiral groove and move along with the linear motion unit 41 in a direction away from the core mold 21, demolding can be completed, and in the process, the preformed impregnated fiber bundles which are solidified and connected with the solidified spiral composite material are synchronously wound in the plastic groove 212, the plastic is further heated, if the length of the molded product is too long, a traction rope can be connected with the middle part of the molded product, so that the mold is smoothly removed, the driving motor is turned off after demolding, and the rotary motor is turned on again.
The above processes are circularly reciprocated, so that continuous production of the composite spiral product is realized.
