Embodiment 1

[0024] Taking a large cylinder winding mold as an example, the design and preparation technology of the present invention will be further described in detail through examples.

[0025] In this embodiment, a cylinder winding mold is combined with figure 1 and figure 2 As shown, it is composed of a housing 1, a mandrel 2, a support mechanism 3 and a head positioning device 4. The support mechanism 3 is divided into an inner ring 31, an outer ring 32, a support rod 33, a locking block 1 34 and a locking block 2 35, the inner ring 31 is an integral structure, and the locking block 1 34 is welded on it; the outer ring 32 is a split structure, which is connected as a whole by the bolts of the locking block 2 35; the support rods 33 are evenly distributed radially along the mandrel 2 , one end of which is connected to the locking block 1 34 of the inner ring 31, and the other end is connected to the locking block 2 35 of the outer ring 32; the inner ring 31 of the support mechanism...

Abstract

The invention relates to a winding forming die for a cylinder and belongs to the technical field of mechanical forming. The winding forming die is composed of a shell, a mandrel, supporting mechanisms and an end socket positioning device. The multiple supporting mechanisms are parallel, are of the same structure and comprise inner rings, outer rings and supporting rods. The inner rings penetrate in the mandrel and are fixed through dowels. The supporting rods are distributed between the inner rings and the outer rings in a radial manner, and the outer rings are fixed to the shell. The shell is fixed through the end socket positioning device. The winding forming die is applied to machine forming and has the beneficial effects of being convenient to mount and demount, reliable in connection, high in rigidity, small in deformation, low in weight and cost and the like.

Description

technical field [0001] The invention relates to a barrel winding molding die, which belongs to the technical field of mechanical molding. Background technique [0002] The filament winding molding process is to wind the continuous fiber (or cloth, prepreg yarn) impregnated with resin glue on the mandrel or inner lining according to certain rules under the control conditions of fiber tension and predetermined molding, and then cured, stripped Mold, to obtain a certain shape of the product. For forming large-sized cylinder products (formed length greater than 5 meters, shell diameter greater than 2 meters) with closed ends, the preparation of molds has always been one of the keys to product manufacturing. The forming mold must not only have good mechanical properties, but also have sufficient strength and rigidity to withstand various loads applied to the mandrel during the product forming process, such as self-weight, product weight, winding tension, curing stress, and secon...
