Problems solved by technology

At present, most of the cylinder winding molding molds adopt the structural form supported by the mandrel and the support rod. If the existing mold structure is applied to the super large cylinder winding molding, it will be difficult to use due to the heavy weight of the mold itself and insufficient strength and rigidity. Distortion occurs, which affects the dimensional accuracy of the final product

Embodiment Construction

[0026] refer to Figure 1 to Figure 7 A further description will be given to the specific implementation of a grid-type cylinder winding molding die of the present invention.

[0027] combine figure 1 and figure 2 As shown, a grid-type cylinder winding molding mold is composed of a front head 1 , a grid-type middle section 2 and a rear head 3 . Such as image 3 As shown, the front head 1 is divided into an end shaft 11, a support rod 12, a support angle box 13, a frame body 14, a web 15, a flange 16, and a head shell 17. The end shaft 11 is a stepped shaft connected to the winding equipment ; The support angle box 13 is evenly distributed along the end shaft 11, and is fixed with the end shaft 11 by screws; one end of the support rod 12 is connected to the head shell 17, and the other end is connected to the support angle box 13; the frame body 14 is a split structure, and the head The shell 17 is connected by screws; the flange 16 is fixed to the end shaft 11 by screws; ...

Abstract

The invention discloses a net rack type cylinder winding forming mold. The mold comprises a net rack type middle segment, the two ends of the net rack type middle segment are detachably connected withsymmetric seal heads, an end shaft is mounted on the center of each seal head, and the outer portion of the net rack type middle segment is connected with a middle segment shell. The structure of twoend shafts is adopted in the mold, a middle spindle is omitted, the self weight and the manufacturing cost of the mold are greatly reduced, meanwhile, a dual-layer joint ball net rack structure is added in the mold, on one hand, the net rack structure is connected with a shell and the front and back seal heads to form a whole structure, the whole rigidity of the mold is improved, winding formingof a super-large cylinder can be achieved, on the other hand, the end shafts are drawn out from the two ends, the net rack structure adopts the detachable connecting manner, and the advantages of being convenient to dismount and mount, reliable in connection, small in deforming and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical design and manufacture, and more specifically relates to a grid-type cylinder winding molding die. Background technique [0002] The filament winding molding process is to wind the continuous fiber soaked in the resin glue solution on the mandrel according to certain rules, and obtain the product after curing and demoulding. For the manufacture of super-large (length greater than 15 meters, diameter greater than 3 meters) cylinder products, mold manufacturing has always been one of the core technologies for manufacturing products. The forming mold must have sufficient strength and rigidity, and must be able to withstand the product forming process Various loads (such as self-weight, product weight, winding tension, curing stress, etc.) applied to the mandrel. The core mold needs to be disassembled and assembled stably (the size of the product manufactured after each disassembly and assembly is...
