[embodiment]
Below in conjunction with accompanying drawing, technological scheme of the present invention is explained in detail.
As shown in Figure 1, be the first mode of execution structural representation of equipment of preparation FRP reinforcing fiber composite metal pipe of the present invention.This equipment comprises fiber frame 1, threading board 2, resin storage tank 3, sub-wire mould 5, buncher 6, the first online knitting machine 7, pre-shaping be heating and curing device 8, traction gear 9 and cutting device 10 successively.
In resin storage tank 3, resin is housed, resin is vinyl ester resins glue in the present invention, is to be mixed by vinyl ester resins, two (the 2-benzene oxygen ethyl) fat of peroxy dicarbonate, peroxidized t-butyl perbenzoate, vinyl benzene, filler and mill base; Wherein, get 100 parts of described vinyl ester resinses, in the weight ratio that adds other each component be: two (2-benzene oxygen ethyl) the fat 0.2-1.0 parts of peroxy dicarbonate, peroxidized t-butyl perbenzoate 0.8-1.8 part, vinyl benzene 2-10 part, filler 3-10 part and mill base 0.5-1.5 part.
With further reference to Fig. 2, sub-wire mould 5 comprises a center hole 52 in central position and several around the equally distributed periphery holes 51 of center hole.Wherein, center hole 52 passes through for metal tube 4, and periphery holes 51 altogether reinforcing fiber 11 is passed through, and because periphery holes 51 is evenly around center 52 pore size distributions, can make reinforcing fiber 11 be distributed in uniformly on metal tube 4 outer walls.
Equipment shown in Fig. 1 is made FRP reinforcing fiber composite metal pipe through following step: (1) starts pulling equipment 9, and reinforcing fiber 11 passes through fiber creel 1, threading board 2, resin storage tank 3 successively, at the coated one deck resin in reinforcing fiber surface; (2) reinforcing fiber 11 soaking after resin passes through the periphery holes 51 of sub-wire mould 5, and metal tube 4 is by the center hole 52 of sub-wire mould 5 simultaneously, and now reinforcing fiber 11 is evenly distributed in metal tube 4 surfaces; (3) reinforcing fiber 11 and metal tube 4 are slowly poured into after buncher 6, and reinforcing fiber 11 enters the online knitting machine 7 of the first online knitting machine 7, the first around metal tube 4 axial rotation, makes reinforcing fiber 11 be wrapped in metal tube 4 surfaces; The winding density of reinforcing fiber 11 can regulate the rotational velocity of online knitting machine 7 to realize according to the specific performance index request to reinforcing fiber composite metal pipe.(4) metal tube 4 being wound around through reinforcing fiber 11 enters pre-shaping device 8 solidifyings that are heating and curing, and enters cutting device 10 by pulling equipment 9, is cut into satisfactory length.
Fig. 4 is the FRP reinforcing fiber composite metal pipe that shown in Fig. 1, equipment makes through above-mentioned steps, and as seen from the figure, metal tube 4 is positioned at the middle part of whole FRP reinforcing fiber composite metal pipe, and reinforcing fiber 11 one directions are wrapped in the outer surface of metal tube 4 uniformly.As preferred version of the present invention, described metal tube is Stainless Steel Tube or copper pipe, and described reinforcing fiber is glass fibre or basalt fibre.This tubing inside is metal tube, and it directly contacts with water but can not cause secondary pollution to water; Be wound with the intensity that FRP reinforcing fiber has improved tubing entirety in the outside of metal tube, the tubing of having avoided the water delivery of independent use metal pipe to cause easily breaks, leakage loss, even the problem such as booster.
As shown in Figure 3, be the second mode of execution structural representation of equipment of preparation FRP reinforcing fiber composite metal pipe of the present invention.Compared to Figure 1 it distinguish and be, it is provided with again the second online knitting machine 71 after the first online knitting machine 7, the second online knitting machine 71 is further introduced new reinforcing fiber 11, to being further wound around by the FRP reinforcing fiber composite metal pipe of the first online knitting machine 7 preliminary winding out, here, the second online knitting machine 71 around the axial sense of rotation of metal tube 4 and the first knitting machine 7 around the axial direction of rotation of metal tube 4, through the structural representation of the FRP of this equipment making reinforcing fiber composite metal pipe as shown in Figure 5, metal tube 4 is still positioned at the middle part of whole FRP reinforcing fiber composite metal pipe, reinforcing fiber 11 prolongs positive and negative both direction and is wrapped in uniformly the outer surface of metal tube 4, this FRP reinforcing fiber composite metal pipe is compared with FRP reinforcing fiber composite metal pipe in the first mode of execution, be wound around owing to having increased reciprocal reinforcing fiber 11, fiber bond stress is strengthened, improve the hoop intensity of FRP reinforcing fiber composite metal pipe, make its quality more stable.
Seen from the above description, for obtaining the FRP reinforcing fiber composite metal pipe that fiber bond stress is stronger, the quantity of preparing online knitting machine in the equipment of FRP reinforcing fiber composite metal pipe of the present invention also can continue to increase, so that reinforcing fiber 11 is tightr and multidirectional wrapping metal tube 4, but should be noted that at this, should notice that online knitting machine is around the axial sense of rotation of metal tube 4, the sense of rotation of an odd number online knitting machine is identical with the sense of rotation of the first online knitting machine 7, even numbers the online sense of rotation of knitting machine and the direction of rotation of the first online knitting machine 7.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is only limited to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
