Description
Technical Field
The utility model relates to an extruder field especially relates to a aircraft nose is extruded to bellows.
Background
The extruders for producing the plastic corrugated pipe comprise a single-screw extruder and a double-screw extruder. A single-screw extruder is generally used only when producing PP, PE and PVC single-wall corrugated pipes and PE and PP double-wall corrugated pipes, and the single-screw extruder is not as good as a double-screw extruder in terms of mixing effect and conveying effect, but the cost of the single-screw extruder is much lower than that of the double-screw extruder. At present, a double-screw extruder is generally adopted, the double-screw extruder conveys materials by the displacement principle of meshing of two threads, pressure backflow does not exist, the corrugated pipe can be directly extruded by powder, the granulating process is omitted, and the cost is saved. In addition, the addition of the powder is adjusted by a hydraulic stepless speed changer, so that the melt pressure during molding and the long-term stability of the section size of the product can be ensured.
The extruder used for plasticizing, conveying materials and providing molding pressure determines the plasticizing effect of the materials, the mixing degree, the uniformity of temperature, the stability of the extrusion pressure and the like, the plasticizing effect has great influence on the internal quality and the appearance gloss of products, the mixing degree can influence the performance uniformity of each point of the products, the nonuniform temperature of the extruded products can easily cause nonuniform sizes and deformation of the products, even cause local overheating decomposition and reduce the performance of the products, and the fluctuation of the extrusion pressure can cause the size fluctuation and unstable production of the products, even cause the phenomenon that the products are blocked or pulled apart.
