Glass fiber reinforced plastic round pipe double-head pultrusion winding equipment

Abstract

The invention discloses glass fiber reinforced plastic round pipe double-head pultrusion winding equipment, which comprises a rack, round pipe molds, a lifting mechanism set on one side of the rack to adjust the vertical position of the round pipe molds, heating plates and core rods arranged on the round pipe molds, two fixation mechanisms disposed at the other side of the rack for fixing the core rods and two winding mechanisms mounted on the rack and positioned between the lifting mechanism and the fixation mechanisms. The round pipe molds are arranged on the lifting mechanism. One ends of the core rods are connected to the round pipe molds, and the other ends are connected to the fixation mechanisms. The invention has the advantage that: the round pipe molds and the core rod fixation mechanisms are arranged on the same rack, thus being convenient for mold calibration at an earlier production stage and easier to control product eccentricity stability. The double-head winding mechanisms are disposed on the same rack, and meanwhile the independence of control is retained, so that the production efficiency is improved, the product rejection rate is reduced, and no additional control difficulty is added.

Description

technical field [0001] The invention relates to a production equipment of a glass fiber reinforced plastic round pipe, in particular to a glass fiber reinforced plastic round pipe double-head wrapping equipment. Background technique [0002] Filament winding and pultrusion are the manufacturing technologies with the longest development history in the composite material industry and have been widely used for a long time. The most prominent feature of the filament winding process is that it is possible to arrange reinforcement materials along the optimal direction according to the load requirements of the composite structure to make products with high structural efficiency. It is especially suitable for the manufacture of composite material structures such as internal pressure vessels, solid rocket motor shells, pipes and storage tanks. It has been widely used in national defense and national economic construction projects, forming a considerable scale of industry. However, f...

Problems solved by technology

But for some small-diameter tubular products, after introducing the winding head, the distance between the mandrel fixing mechanism and the outer mold cavity is greatly increased, resulting in a large increase in the length of the mandrel. The longer the mandrel, the easier it is to produce. Swing, the eccentricity of the product after the mold is not stable
