A smart energy large-scale composite core pultrusion process and device

Abstract

The invention discloses a smart energy large-size composite core pultrusion process and device. The device comprises yarn dividing devices, a main resin dipping groove, resin extruding rollers, a yarn collecting device, a curing die, pre-curing dies, a first auxiliary resin dipping groove, resin scraping devices and a second auxiliary resin dipping groove. The main resin dipping groove comprises a first main resin dipping groove position and a second main resin dipping groove position; the pre-curing dies are arranged above the main resin dipping groove and comprise the first pre-curing die, the second pre-curing die and the third pre-curing die which are sequentially arranged; the resin scraping devices comprise the first resin scraping device, the second resin scraping device and the third resin scraping device and provided with inlets of the three pre-curing dies; and the smart energy large-size composite core pultrusion device comprises the main resin dipping groove with two groove positions and two auxiliary resin dipping grooves, most carbon fibers and all glass fibers are subject to resin dipping through the main resin dipping groove, a small part of carbon fibers are subject to resin dipping through the auxiliary resin dipping grooves, rein in the groove is not heated and is not prone to aging, and quality stability of a core stick is improved.

Description

technical field [0001] The invention relates to a pultrusion process and device for a large-scale composite core of smart energy. Background technique [0002] With the promotion of the application of composite wires, State Grid Corporation has developed a strong interest in large-scale composite wires. However, at present, the size of the large-scale composite core is too large, and curing requires a higher temperature. It may have insufficient internal curing degree and excessive curing of the surface resin. The number of fibers used in large-scale composite cores is large, and the fibers are immersed in resin in multiple layers at the same time, resulting in insufficient fiber impregnation. There must be defects inside the produced composite cores, which poses a great safety hazard when used; and large-scale The composite core pultrusion speed is too slow, the production efficiency is low, and the labor cost remains high.
