Fig. 3 is the structural representation of the die assembly embodiment that uses in the fiberglass wet method winding process among the present invention.
The specific embodiment
The embodiment of the die assembly that uses in the fiberglass wet method winding process is shown in Fig. 1 ~ 3: comprise the format roll 10 that is used for the corresponding glass fiberizing and be arranged at the back shaft 11 at format roll 10 two ends that back shaft 11 drives in respective drive mechanism can drive format roll 10 rotations down.All suit is fixed with the mold tooling adaptive with format roll on each back shaft; Mold tooling comprises the roller joint 9 that is fabricated from iron; Roller joint 9 makes itself and the relatively-stationary fixed connection structure of format roll when being provided with and using; Roller joint 9 comprises the top connection 1 and lower contact 4 to being fitted together up and down; The periphery of top connection 1 has top connection periphery arc surface 1-1, and 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, and upper and lower joint periphery arc surface docks and forms the complete external diameter cylindrical peripheral face identical with the external diameter of format roll.End end face after the butt joint of upper and lower joint has also constituted the docking structure that dock with the axial end of format roll, when the docking structure of roller joint 9 with after the corresponding axial end of format roll docks, 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 back shaft mounting groove 6 of going up along top connection 1 that is provided with in the top connection 1; Fixed connection structure also is included in the axially extended and last back shaft mounting groove 6 complementary following back shaft mounting grooves 5 that dock along lower contact 4 that are provided with in the lower contact 4, and the cell wall of upper and lower back shaft mounting groove has surrounded to be used for coincideing and has been set in the back shaft installing hole on the corresponding back shaft.Top connection 1 away from an end of docking structure be installed with towards away from the docking structure axis of orientation to the top connection adpting flange 7 that overhangs; Lower contact 4 away from an end of said docking structure be installed with towards away from the docking structure axis of orientation to the lower contact adpting flange 8 that overhangs; Fixed connection structure also comprises the bolt fastening structure 3 that is arranged between the upper and lower joint adpting flange, and bolt fastening structure comprises and is arranged at the bolt penetration hole on the upper and lower adpting flange respectively and is threaded onto the connecting bolt in the bolt penetration hole.Be distributed with on the outer peripheral face of upper and lower joint and a plurality ofly be used for that the corresponding glass fibre that soaked resin is run through and the iron nail 2 of the rod-like structure of block, be provided with between the adjacent iron nail 2 and be used for detour after by the block gap of switching-over of glass fibre.
During use; Two roller joints are loaded on respectively on the corresponding back shaft; And the corresponding axial end that makes docking structure and the format roll of each the roller joint butt joint that coincide since the external diameter of each roller joint all the external diameter with format roll is identical, so each roller joint all can not influence the winding process of corresponding glass fiber on format roll; When the glass fibre that soaked resin around when need commutate in the end of format roll; Glass fibre is run through by the iron nail of correspondence and fix, glass fibre through the switching-over of detouring of the gap between adjacent iron nail, carries out the laying of next frp layer subsequently then; Around when need commutate in the other end end of format roll, carry out same operation at glass fibre.Because the block effect of iron nail, relative skidding can not take place in the glass fibre that is in each glass layer end, has guaranteed the uniformity of the glass reinforced plastic pipe termination laminate structures after the moulding.So need not twine thicker glass layer yet, be convenient to glass reinforced plastic pipe and solidify excision termination, back waste material, reduce the fraction defective of product, improve operating efficiency in the end of format roll; Each roller joint includes upper and lower joint simultaneously, and upper and lower joint has made things convenient for correspondence through the bolt fastening structure releasable connection.
In other embodiment of this die assembly: the roller joint can also be an overall structure; The through hole that supplies corresponding back shaft to pass need be set in the roller joint this moment; This moment fixed connection structure can be on the end of roller joint, be provided with near said format roll in turn edge; In turn edge and 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, through connecting bolt format roll and respective roller joint is linked together; When the roller joint is between back shaft and format roll; The through hole that supplies back shaft to pass also can be set on the roller joint, and fixed connection structure comprises and is arranged at the syndeton between back shaft and the respective roller joint and is arranged at the syndeton between roller joint and the shaping axle; Certainly when the length of format roll only needs a side that back shaft is set than weak point, can the roller joint directly be loaded on the end of format roll away from back shaft; Iron nail can also be replaced by the pin of other rod-like structure certainly, and this moment, glass fibre can by block, the number of iron nail also can be adjusted respectively according to actual needs through the corresponding lever of pile warp.
The embodiment of mold tooling is shown in Fig. 1 ~ 2: the mold tooling described in the die assembly embodiment that uses in the concrete structure of this mold tooling such as the above-mentioned fiberglass wet method winding process is not described in detail in this.
