Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of the die assembly embodiment that uses in fiberglass wet-winding craft in the present invention.
The specific embodiment
The embodiment of the die assembly using in fiberglass wet-winding craft is as shown in Figures 1 to 3: comprise for the format roll 10 of corresponding glass fiberizing and be arranged at the back shaft 11 at format roll 10 two ends, back shaft 11 is under respective drive mechanism drives and can drive format roll 10 to rotate.On each back shaft, be all set with the mold tooling being fixed with format roll adaptation, mold tooling comprises the roller joint 9 being fabricated from iron, on roller joint 9, be provided with and while using, make itself and the relatively-stationary fixed connection structure of format roll, roller joint 9 comprises up and down to the top connection 1 being fitted together and lower contact 4, the periphery of top connection 1 has top connection periphery arc surface 1-1, the periphery of lower contact 4 has the lower contact periphery arc surface 4-1 that coincide and dock with top connection periphery arc surface 1-1, on, lower contact periphery arc surface docks and a cylindrical peripheral face that complete external diameter is identical with the external diameter of format roll of formation.One end end face after upper and lower joint docking has also formed the docking structure docking with the axial end of format roll, after the docking structure of roller joint 9 and the corresponding axial end docking of format roll, and the outer peripheral face continuous transition of the outer peripheral face of roller joint 9 and format roll.Fixed connection structure is included in the axially extended upper support axle mounting groove 6 along top connection 1 arranging in top connection 1, fixed connection structure be also included in lower contact 4 arrange along the axially extended of lower contact 4 and the complementary lower support axle mounting groove 5 docking of upper support axle mounting groove 6, the cell wall of upper and lower back shaft mounting groove has surrounded for identical and has been set in the back shaft installing hole on corresponding back shaft.Top connection 1 away from one end of docking structure be installed with towards away from docking structure axis of orientation to the top connection adpting flange 7 overhanging, lower contact 4 away from one end of described docking structure be installed with towards away from docking structure axis of orientation to the lower contact adpting flange 8 overhanging, fixed connection structure also comprises the bolt fastening structure 3 being arranged between upper and lower joint adpting flange, and bolt fastening structure comprises and is arranged at respectively the bolt penetration hole on upper and lower adpting flange and is threaded onto the connecting bolt in bolt penetration hole.On the outer peripheral face of upper and lower joint, be distributed with the iron nail 2 of a plurality of rod shaped structure, the corresponding glass fibre that soaked resin being run through by it for block, is provided with the gap of the commutation of detouring after by block for glass fibre between adjacent iron nail 2.
During use, two roller joints are loaded on respectively on corresponding back shaft, and make the docking that coincide of the docking structure of each roller joint and the corresponding axial end of format roll, because the external diameter of each roller joint is all identical with the external diameter of format roll, so each roller joint all can not affect the winding process of corresponding glass fiber on format roll, when soaking the glass fibre of resin and need to commutate in the end around to format roll, first make glass fibre be run through and fix by corresponding iron nail, glass fibre is subsequently through the commutation of detouring of the gap between adjacent iron nail, then carry out the laying of next frp layer, when glass fibre need to commutate around to the other end end of format roll, carry out same operation.Due to the block effect of iron nail, can there is not relative skidding in the glass fibre in each glass layer end, guaranteed the uniformity of the glass reinforced plastic pipe termination laminate structures after moulding.So also need to not be wound around thicker glass layer in the end of format roll, be convenient to after glass reinforced plastic pipe solidifies excise termination waste material, reduce the fraction defective of product, improve operating efficiency; Each roller joint includes upper and lower joint simultaneously, and upper and lower joint is bolted structure releasable connection, has facilitated correspondence.
In other embodiment of this die assembly: roller joint can also be an overall structure, the through hole passing for corresponding back shaft now need to be set in roller joint, now fixed connection structure can be in roller joint, on the one end near described format roll, arrange in turn edge, on inside turning edge, be provided with bolt penetration hole, the corresponding axial end of format roll is provided with the screwed hole corresponding with each bolt penetration hole position, by connecting bolt, format roll and respective roller joint is linked together; When roller joint is between back shaft and format roll, the through hole passing for back shaft also can be set on roller joint, and fixed connection structure comprises and is arranged at the syndeton between back shaft and respective roller joint and is arranged at the syndeton between roller joint and shaping axle; Certainly when the length of format roll is compared with short and while only needing a side that back shaft is set, roller joint directly can be loaded on to format roll away from one end of back shaft; Iron nail can also be replaced by the pin of other rod shaped structure certainly, and now glass fibre can by the corresponding lever of pile warp, by block, the number of iron nail also can be adjusted respectively according to actual needs.
The embodiment of mold tooling is as shown in Fig. 1～2: the mold tooling of the concrete structure of this mold tooling described in the die assembly embodiment using in above-mentioned fiberglass wet-winding craft, is not described in detail in this.
