Embodiment 1

[0026] Such as figure 1 As shown, the present invention includes an outer frame 4, an inner core mold 1 located inside the outer frame 4 and corresponding to the inner profile structure of the processed composite material profile 2, and an inner core mold 1 located outside the inner core mold 1 and whose inner profile structure is the same as that of the inner core mold. The pressure-bearing sheet 3 corresponding to the external surface structure of the core mold 1, and the force-applying mechanism that presses the processed composite material profile 2 placed between the inner core mold 1 and the pressure-bearing sheet 3 from all sides through the outer frame 4 5. The inner mandrel 1 and the pressure-bearing sheet 3 are formed for forming L, U, H or Profile The internal molding structure of a profile. The number of the inner mandrel 1 is one or more, and the cross-sectional shape of the inner mandrel 1 is rectangular or L-shaped. The outer frame 4 is a rectangular frame o...

Embodiment 2

[0031] Such as figure 2 As shown, in this embodiment, the force applying mechanism 5 is a shrinkage tape 5-2 wrapped outside the outer frame 4, and the outer frame 4 is a circular frame with a cavity inside. Therefore, in the molding process of the processed composite material profile 2 by using the present invention, the purpose of controlling the pressure applied to the composite material profile product is achieved by adjusting the tension of the shrinkage tape 5-2. In this embodiment, the structures, connections, functions and working principles of other components are the same as those in Embodiment 1.

Embodiment 3

[0033] Such as image 3 As shown, in this embodiment, the processed composite material profile 2 is a U-shaped profile made of glass fiber impregnated epoxy resin adhesive tape, and the number of pressure-bearing sheets 3 used is three and their shapes are uniform. It is rectangular, and the positions of the three pressure-bearing sheets 3 correspond to the U-shaped processed composite material profiles 2 placed on the three adjacent side walls outside the inner mandrel 1. The structure, connection relationship, and The function and working principle are the same as those in Embodiment 1.

[0034] When adopting the present invention to carry out the molding process of the processed composite material profile 2, firstly, the glass fiber impregnated epoxy resin adhesive tape is cut and laid on the three adjacent side walls of the steel mandrel according to the U shape, that is, first Completing the layering of the composite material profile products; then correspondingly laying...

Abstract

The invention discloses a sizing device of composite profiles. The sizing device comprises an outer frame; an inner core die which is located inside the outer frame and corresponds to an inner profilestructure of a machined composite profile; a bearing sheet which is located outside the inner core die and the inner profile structure thereof corresponds to an outer profile structure of the inner core die; and a force application mechanism which lays stress on the composite profile to be processed arranged between the inner core die and the bearing sheet from the periphery by the outer frame; the bearing sheet is a bearing structure which evenly distributes acting force applied by the force application mechanism on the composite profile to be processed; and one or a plurality of the bearingsheets are located outside the inner core die. The sizing device has the advantages of simple structure, low manufacturing cost, convenient assembly, disassembly and operation; and can effectively solve practical problems of enormous investment on die assembly and equipment of the existing large-sized composite profiles and the like.

Description

technical field [0001] The invention belongs to the technical field of composite material profile production and manufacturing, and in particular relates to a shaping device for composite material profiles. Background technique [0002] At present, the methods for shaping composite material profiles mainly include drawing, injection molding, molding, etc., but in the actual application process, the above methods all have the following shortcomings and deficiencies: First, the drawn and formed products only have fiber reinforcement in one direction, Therefore, the molded products have obvious anisotropy; secondly, during injection molding and compression molding, the mold cost is high, thus increasing the manufacturing cost of the product; thirdly, compression molding can only exert pressure on one direction of the product at the same time , so it is difficult to form such as U, H, Fourth, when forming large-size multilateral profiles, the investment in molds and equipment ...
