Before winding, the shell plate can be coated with fragile and fusible materials (such as water-soluble gypsum, paraffin and the like which are used for demoulding the wound product). During winding, the winding machine winds the surface of gypsum or paraffin according to a working instruction, and after the winding is finished, the die and the whole fiber enter an oven for curing; after the product is hot-pressed and solidified, a worker can remove the shell plate flange outside the cylinder body, then the shell plate flange enters the cylinder body to disassemble the supporting mechanism, the mandrel is drawn out from one end after the supporting mechanism is disassembled, gypsum and paraffin are cleaned, and the product and the die are quickly and efficiently separated.
Further, the supporting mechanism comprises a ring frame, the ring frame is arranged along the length direction of the mandrel at equal intervals, the outer surface of the ring frame is connected with the shell plate, a plurality of supporting rods are arranged between the inner surface of the ring frame and the mandrel, and the supporting rods are radially and uniformly distributed along the circumferential direction of the mandrel.
Furthermore, the supporting mechanism further comprises inclined supports arranged at two ends of the mandrel, the inclined supports are connected with the shell plate, and the axial rigidity is increased due to the arrangement of the inclined supports.
Furthermore, a connecting support is arranged on the mandrel, and the support rod and the inclined support are fixed on the connecting support. The connecting support is a single part and is connected to the mandrel through a screw, one end of the supporting rod or the inclined support is connected with the connecting support, and the other end of the supporting rod or the inclined support is directly connected with the ring frame or the shell plate.
Furthermore, the ring frame is of a split structure, and the section of the ring frame is a T-shaped pultrusion section.
Further, the dabber is notch cuttype tubular structure, and thick both ends are little in the middle of it, dabber middle section surface is provided with and is used for the installation the support installation face of connecting the support. The middle section mandrel is not integrally processed, only a welded support mounting surface needs to be machined, machining time and difficulty are greatly reduced, and the mounting surface serves as an assembly reference, so that assembly precision is guaranteed.
Further, the shell plate flange is a circular flange plate.
In summary, the shell plates of the utility model are split cast aluminum shell plates, and are connected by the connecting plates, so that the shell plates are staggered front and back during installation, thereby increasing the overall compression resistance and torsion resistance of the shell plates; a supporting mechanism is arranged between the shell plate and the mandrel, so that the winding forming of the large-length large-diameter cylinder body is realized; the middle section of the mandrel is not integrally machined, and only the welded mounting surface is machined, so that the machining time and the machining difficulty are greatly reduced. The utility model discloses still have install and remove convenient, the location is reliable, the benchmark is clear and definite, rigidity is big, the deformation is little and characteristics such as with low costs, realized the winding shaping of super large-scale rocket combustion chamber shell or other tube structure.
