A winding composite core pultrusion impregnation process for smart energy and its special impregnation device

Abstract

The invention discloses a winding type composite core pultrusion impregnation process for smart energy and a special impregnation apparatus therefor. The impregnation apparatus comprises a first yarn-splitting frame, a first impregnation groove, a first adhesive extruding roller, a second yarn-splitting frame, an adhesive scraper, a first yarn collector, a winder, a pre-curing die, a curing die, a second impregnation groove, a second adhesive extruding roller and a second yarn collector that are arranged on a tooling bracket, wherein an upper yarn-splitting device and a lower yarn-splitting device are arranged at the upper and lower ends of the first yarn-splitting frame respectively; the first adhesive extruding roller and the second adhesive extruding roller are arranged at the upper parts of the first impregnation groove and the second impregnation groove respectively; the second yarn-splitting frame and the adhesive scraper are arranged at the front part of the first yarn collector; the first yarn collector is arranged at the front part of the winder; and the winder is arranged at the front part of the pre-curing die. According to the winding type composite core pultrusion impregnation process and the impregnation apparatus, continuous winding can be realized through the winder so as to produce the winding type composite core; the composite core is under transverse protection, so that the cracking of the composite core is avoided, and the composite core is safer to use; and in addition, the composite core is subjected to impregnation first and then is winded, so that the internal defects of a core rod caused by incomplete impregnation is prevented, so that the winding type composite core pultrusion impregnation process and the impregnation apparatus can be widely popularized.

Description

technical field [0001] The invention relates to a pultrusion impregnation process of a winding composite core for smart energy and a special impregnation device thereof. Background technique [0002] With the promotion of the application of composite wires, the requirements for composite cores are getting higher and higher, and people's research on composite cores is no longer limited to direct dragging pultrusion, and winding and stranded composite cores have been proposed and further developed. Research, because the winding type and the twisted type have special performance characteristics and can meet the application requirements of different occasions, the research and promotion of this aspect should be accelerated. The winding type composite core is wrapped with a layer of carbon fiber so that the mandrel is not easy to crack when it is subjected to radial pressure. At present, the development of the winding type has been slow due to the complexity of the tooling. There...

Problems solved by technology

The winding type composite core is wrapped with a layer of carbon fiber so that the mandrel is not easy to crack when it is subjected to radial pressure. At present, the development of the winding type has been slow due to the complexity of the tooling. Therefore, it is necessary to propose a simple winding process without increasing production. In the case of low cost, the composite core has the performance characteristics of winding type
