Problems solved by technology

[0004] Products produced by integral molding have the advantages of high dimensional accuracy, high strength, and light weight. At the same time, they can improve the transmission performance of electromagnetic waves, but they have the disadvantage of difficult molding.
[0005] After dismantling complex composite structural parts into simple parts, the products produced by molding and assembling one by one have the advantages of simple forming, but subsequent assembly is difficult, which easily leads to the disadvantages of overweight and low dimensional accuracy
For products with wave-transparent performance, it is easy to reduce the wave-transparent performance of the product

Embodiment Construction

[0032] This structure is applied in the molding process of a certain type of vertical tail transmitting radome. The invention aims to solve the problem of difficulty in forming and demolding composite material structural parts with bidirectional underdrawing angles. The protection point of the present invention mainly lies in the formation and release of the two-way inverted angle composite material structural parts composed of the base 1, the parting body 2, the top pressing screw 3, the side tensioning screw 4, the demoulding screw 5, and the stop block 6. Modeling methods and special devices.

[0033] Below in conjunction with accompanying drawing this patent is described in detail:

[0034] A method for forming a composite material structural part with a complex profile. The specific steps of using the above-mentioned special device for forming a composite material structural part with a complex profile are as follows:

[0035] Step 1: Assemble the positioning boss of th...

Abstract

The invention relates to a special device for forming a complex surface composite material structural part. The device is characterized by comprising a base (1), a die splitting body (2), a top pressing screw (3), and a side tensioning screw rod (4), the base (1) is provided with a positioning boss which can be matched and installed with the die splitting body (2), a first threaded hole (7) is formed in the upper part of the base, a first through hole (8) is formed in the side wall of the base; a positioning groove matched with the positioning boss of the base (1) is arranged on the die splitting body (2), a second through hole (9) and a third threaded hole (12) are formed in the upper part of the positioning groove; the top pressing screw (3) penetrates through the second through hole (9)and is connected with the first threaded hole (7); a second threaded hole (10) is formed in the side wall of the positioning groove, the side tensioning screw rod (4) penetrates through the first through hole (8) and is connected with the second threaded hole (10). According to the device, the overall forming machine demoulding of the composite material structural part with the bidirectional inverted structure can be realized, and the product precision is ensured.

Description

[0001] Field [0002] The invention belongs to the technical field of process equipment, and in particular relates to a forming method and a special device for a composite material structural part with complex profiles. technical background [0003] Composite structural parts have the advantages of light weight, high strength and rigidity, good molding processability, etc., and are more and more widely used in the aircraft manufacturing process. With the diversity of aircraft uses, the composite structural parts assembled into aircraft are becoming more and more complex. In order to realize the product structure, the method of reassembling after integral molding or single-piece molding is generally adopted. [0004] Products produced by integral molding have the advantages of high dimensional accuracy, high strength, and light weight. At the same time, they can improve the transmission performance of electromagnetic waves, but they have the disadvantage of difficult molding. ...
