Technical Field

The invention belongs to the field of winding, forming and manufacturing of fiber reinforced composite material strips, and particularly relates to a winding, cladding and forming device and method of a fiber reinforced composite material strip.

Background

The composite material is widely applied to the fields of aerospace, chemical engineering, civil engineering and the like due to the excellent characteristics of high specific strength, high specific modulus, light weight and the like. The first condition of the application of the composite material in multiple fields is the molding manufacture of the composite material, and the winding molding manufacture is one of the methods for molding and manufacturing the composite material, and the method is widely applied to the molding manufacture of cylindrical pipes, conical or approximately conical rotary parts.

The composite material winding forming process includes winding composite material belt around the surface of mold to form the prefabricated product, and curing and demolding. Compared with other winding processes, the oblique winding process can be applied to the forming process of various parts such as pipes, conical parts and the like, can flexibly select the winding direction, and has wider process applicability. In the process of winding a composite prepreg tape onto a conical core mold by using an oblique winding process to form a preform, how to tightly wrap the composite tape on the surface of a mold or on an upper winding layer is a key problem, and if the composite tape is not tightly wrapped, defects such as folds or pores can occur, and the defects can directly cause the quality and performance of a composite product to be reduced.

In order to solve the key problem that the composite material belt is tightly wrapped on the surface of a mould or a winding layer on the mould and does not generate folds, the prior art has the following three methods:

one is a deformable bias-cut cloth belt. In order to realize the deformability of the prepreg tape, the oblique winding process adopts a cutting process along the 45-degree angle direction of the warp of the prepreg resin fiber woven cloth to manufacture the oblique cutting prepreg tape consisting of discontinuous short fibers. The cloth belt cut by the method is discontinuous, the requirement of oblique winding extension deformation rate is required to be met, a plurality of joints exist in the composite material prefabricated product, the winding efficiency is low, and the deformation stability of the prepreg belt is poor.

And secondly, the deformation of the prepreg tape is realized by adopting a rigid conical compression roller system. By applying winding pressure and tension to the prepreg tape, the prepreg tape is rolled and deformed by the rigid conical pressing roller, so that a shape of the prepreg tape that can adapt to the oblique winding surface is obtained. However, the rigid conical roller system is suitable for the forming process of products with small winding angles along with a self-parallel and flat-folding winding process. When the winding angle of the product is increased or the radius of the wound product is reduced, the half cone angle of the press roller needs to be increased to meet the requirement of the extension deformation rate of the oblique winding process, different conical press rollers need to be adopted, and the complexity of the process is increased. The oblique winding rigid conical compression roller system has a plurality of limitations in the application of oblique winding products with large winding angles and large size change ranges, depends on manual operation, and influences the production efficiency and the qualification rate.

Thirdly, a differential deformation system and an uncoiling speed regulation system are adopted to form a flexible deformation system of the prepreg tape. The uncoiling speed regulating system conveys the prepreg tape to a differential deformation system based on the current winding speed; the differential wheel array is the key of the differential deformation system, and according to information such as a winding angle, a mould size and the like, multi-point speed regulation control is completed along the width direction of the prepreg tape, so that accurate deformation of the prepreg tape is realized. The method depends on rolling and spreading the prepreg tape to deform as a rigid conical pressing roller system, and because the speed of a differential wheel array in the differential deformation system is adjustable, the method has wide adaptability and good stability compared with the rigid conical pressing roller system, but the rolling and spreading can damage the prepreg tape, and hidden dangers exist inside the produced composite material product.

As shown in 16 and 17, the variable speed guide roll 3-4 comprises a roll shaft 3-4-1, a bearing baffle ring 3-4-2, a third bearing 3-4-3, a guide ring 3-4-4, a bearing end cover 3-4-5 and a screw 3-4-6; the roller shaft 3-4-1 is provided with a plurality of guide rings 3-4-4, each guide ring 3-4-4 is connected with the roller shaft 3-4-1 through a third bearing 3-4-3, the guide rings 3-4-4 are in transition fit with the third bearings 3-4-3, guide grooves 3-4-5 on the guide rings 3-4-4 can prevent yarn from slipping, the third bearings 3-4-3 are in clearance fit with the roller shaft 3-4-1, bearing baffle rings 3-4-2 are arranged between the third bearings 3-4-3, the bearing baffle rings 3-4-2 are sleeved on the roller shaft 3-4-1 to prevent the third bearings 3-4-3 from interfering with each other; the bearing end cover 3-4-5 is arranged at one end of the roll shaft 3-4-1, and the screw 3-4-6 penetrates through the bearing end cover 3-4-5 to be connected with the roll shaft 3-4-1 so as to tightly press the third bearings 3-4-3; the other end of the roll shaft 3-4-1 is mounted on a support plate 3-6 through bolts. The third bearing 3-4-3 and the guide ring 3-4-4 form rollers, the rollers on the variable-speed guide roller 3-4 can move independently, the requirements of different speeds of the warp yarns can be met, the adaptability is wide, and the friction between the yarns and the guide ring 3-4-4 can be reduced by adopting the roller mode. The production of composite winding fiber belts with different widths can be realized by increasing or reducing the number of rollers on the variable-speed guide rollers 3-4, and the guide rings 3-4-4 are provided with guide grooves 3-4-5, so that the slippage of warps can be prevented.

As shown in fig. 18, the support plate 3-6 is T-shaped, the cross bar is provided with a plurality of through holes 3-6-1, and the vertical rod is provided with a vertical through groove 3-6-2; the variable-speed guide roller 3-4 is arranged in the through hole 3-6-1 and the through groove 3-6-2, and when the position of the variable-speed guide roller 3-4 in the middle needs to be adjusted, the position of the variable-speed guide roller can be adjusted up and down in the through groove 3-6-2.

A method of winding an overmolding device in accordance with the fiber-reinforced composite tape, comprising the steps of: the warp yarn bypasses the variable speed guide roller 3-4 of the guide part 3, enters the winding disc shaft 2-11 of the winding part 2, is integrated into a row at the yarn outlet hole 2-16-1 of the yarn collecting plate 2-16, the winding disc 2-7 rotates under the drive of the drive device, the weft yarn on the yarn cylinder shaft 2-6 has certain tension under the action of the resistor 2-5, passes through the yarn inlet head 2-8 and is led out by the yarn outlet head 2-13, and is tightly wound on the surface of the warp yarn which passes through the yarn collecting plate 2-16 to form the winding and cladding forming of the composite material belt.
