Description

Rapid splicing tool for fiber-laying prepreg

Technical Field

The utility model belongs to combined material processing field specifically is a shop's silk preimpregnation material splices frock fast.

Background

The maturation of advanced technology in composite materials has made it possible to optimize their performance and to reduce their cost, thus greatly driving the use of composite materials in aircraft. Some large aircraft manufacturers are gradually reducing the proportion of traditional metal working in aircraft design and manufacture, with composite manufacturing being preferred. The automatic filament spreading technology is a full-automatic composite material processing technology developed in the 70 th century by integrating the advantages of two composite material forming technologies of a fiber winding technology and an automatic tape spreading technology. During the automated fiber placement process, it is necessary to join the broken prepreg tows together. Typically, specialized splicing equipment is used or pressure sensitive tape is used for manual splicing, but in the absence of specialized equipment or where rapid completion of the splicing of the cut, threaded prepreg splices becomes difficult to splice together with high quality. And the splicing parallelism of the tow joints is difficult to control by manually bonding with the pressure-sensitive adhesive tape, so that the joints are stuck in the pipeline of the automatic fiber laying machine in the fiber laying process.

SUMMERY OF THE UTILITY MODEL

Under this form, when lacking professional equipment or requiring to accomplish the concatenation of shop's silk preimpregnation material fast, this novel frock provides a shop's silk preimpregnation material splices frock fast, and concrete technical scheme is as follows:

the utility model provides a shop's silk preimpregnation material splices frock fast, includes base and top apron, the base is equipped with the recess that a plurality of width differs, be equipped with on the top apron with the boss that the recess corresponds.

Put into the recess from opposite direction respectively one on the other with two disconnected preimpregnation silks, can put into corresponding recess according to the width that preimpregnation material tow connects, the overlap portion length range 5~8cm of two preimpregnation areas, pass through base and top apron with this kind of shop's silk preimpregnation material quick concatenation frock and coincide, recess and boss are laminated promptly, utilize the autohension between the preimpregnation material, with predetermined width shop's silk preimpregnation material tow connect the concatenation well under the circumstances of exerting external force, divide base and top apron and can take out the joint that has spliced.

The further improvement lies in that: the base and the top cover plate are both made of metal steel.

The further improvement lies in that: and bosses with the same number as the grooves are arranged on the top cover plate. Such a set of tools can be used to splice joints of prepreg filaments of different widths.

The further improvement lies in that: the three surfaces of the groove are coated with PTFE coatings which play a role in preventing the prepreg filaments from being adhered to the two side surfaces and the bottom surface of the groove.

The further improvement lies in that: the width and the length of the base and the top cover plate are consistent.

The further improvement lies in that: the base is 5-10 cm in length and 5-6 cm in width. The comparison of the width and the length is beneficial to being held by hands, and the operation is very convenient.

The further improvement lies in that: each groove is fully engaged with a corresponding boss.

The beneficial effects of the utility model, the utility model provides a spread silk preimpregnation material and splice frock fast can accomplish effectively and connect the joint operation when lacking professional equipment or requiring to accomplish the concatenation of the silk preimpregnation material fast, and this frock simple structure, preparation process are simple, have maintainability height, splice advantages such as strong, long service life, convenient to use.

Detailed Description

In order to further understand the present invention, the following detailed description will be made with reference to the accompanying drawings and examples, which are only used for explaining the present invention and do not limit the scope of protection.

The utility model provides a shop's silk preimpregnation material splices frock fast, as shown in fig. 1-2, including base 1 and top apron 6, the two all adopts the metal steel to make, and the two length is unanimous with the width, be equipped with three recess 5 on the base 1, be the recess 2 that the width is 3.175mm respectively, the recess two 3 that the width is 6.35mm, the recess three 4 that the width is 12.7mm, be equipped with the boss 7 that the width is 3.175mm that corresponds on the top apron 6, the boss two 8 that the width is 6.35mm and the boss three 9 that the width is 12.7mm, three boss and three recess mesh one by one respectively are leveled, base 1 and top apron 6 can laminate completely, the junction of base 1 and top apron 6 scribbles PTFE coating 5, can play and prevent that the preimpregnation silk from gluing on the internal surface face of recess. The width of the groove 5 may be set as required, and is not limited to the width dimension in the present embodiment.

The tool for quickly splicing the laid fiber prepreg is simple in structure, very simple in preparation and production, high in maintainability, convenient to use and long in service life.

Taking splicing of 6.35mm wide fiber-spread prepreg tow joints as an example, a fiber-spread prepreg rapid splicing tool is put into an oven in advance to be preheated for 30 minutes at the temperature of about 40-50 ℃. In the splicing process, as shown in fig. 3, two disconnected prepreg wires 10 are placed into a 6.35mm groove II 3 from opposite directions one above the other respectively, the placing length is 5-10 cm, the length range of the overlapped part of the two prepreg wires 10 is 5-8 cm, the laid fiber prepreg fast splicing tool is combined with a top cover plate 6 through a base 1, the 6.35mm groove II 3 is combined with a 6.35mm boss II 8, the 6.35mm groove II 3 and the 6.35mm boss II 8 are combined, the 6.35mm wide laid fiber prepreg strand connector is spliced under the condition of applying external force by utilizing the self-adhesiveness between the prepreg materials, and the spliced connector can be taken out after the base 1 and the top cover plate 6 are separated due to the fact that the sizes of the top cover plate 6 and the base 1 are small, the external force can be applied by a hand for 50-100N, and the external force can be removed after 30-60 seconds.

When professional equipment is lacked or the joint splicing of the fiber-laid prepreg is required to be completed quickly, the fiber-laid prepreg quick splicing tool can be used for carrying out quick joint combination operation; moreover, grooves with the widths of 3.175mm, 6.35mm and 12.7mm are formed in the filament-laid prepreg rapid splicing tool in the embodiment, so that the filament-laid prepreg rapid splicing tool can meet splicing requirements and accuracy of various types of filament-laid prepregs, and can perform splicing work simultaneously in multiple lines.
