Abstract
The invention discloses a production process of a three-hole hollow plate section bar. Glass fiber yarns and a composite felt are prepared. Upper parts of the glass fiber yarns are arranged in three-hole shapes, and lower parts of the glass fiber yarns are tiled. The glass fiber yarns are dipped in a dipping tank. Upper and lower heating plates are arranged in the dipping tank. The dipped glass fiber yarns are made to pass through a pre-forming device which is provided with three grooves. The upper parts of the glass fiber yarns are guided in the first groove; the lower parts of the glass fiber yarns are guided in the second groove; and the composite felt guided out from a side surface is guided in the third groove. A pre-formed section bar is fed in a three-hole pultrusion mold for final formation. Six heating pipes are arranged in the three-hole pultrusion mold. The finally formed three-hole hollow plate section bar is fed in a traction device, is towed to a cutting device for cutting, and is sprayed with anti-ageing fluorocarbon paint. The production process has the advantages of low production cost and suitability for large-scale production.
