A basalt fiber winding composite pipe forming device

Abstract

The present invention designs a basalt fiber winding composite pipe forming device, which includes four parts: fiber unwinding, tension control, dipping, and fiber winding; the fiber unwinding part includes unwinding rollers, unwinding shafts, and torque motors; The control part includes the main speed roller, magnetic powder brake, and tension detection mechanism; the dipping part includes the dipping pool, dipping roller, and extrusion roller; the fiber winding part includes racks, incomplete gears, helical gear reversing mechanisms, support tables and Guide rail, guide wheel, composite pipe, mandrel, three-jaw chuck, spinning nozzle, there is an incomplete gear on each side of the rack, the spinning nozzle is fixed on the rack, and the helical gear reversing mechanism drives the incomplete gear to synchronize turn. The invention adopts a horizontal structure, each part does not interfere with each other, has strong stability, can keep the tension constant during the fiber winding process, can ensure that the basalt fiber is evenly wound on the surface of the composite pipe, and improves the mechanical properties of the composite pipe.

Description

technical field [0001] The invention relates to a composite pipe surface fiber winding device used in the field of basalt fiber winding. Background technique [0002] Fiber-reinforced composite pipe is an integrated composite pipe formed by regularly winding fibers on the outer surface of the pipe. Fiber-wound products have a significant effect on the mechanical properties and physical properties of the reinforced material, improving the performance of the material in engineering. [0003] Currently, filament winding usually uses carbon fibers. Carbon fiber has high strength and light weight, but carbon fiber is a brittle material, and it will break directly if it is too strong. After damage, it cannot be repaired and can only be replaced. At the same time, the content of harmful chemical components is high, which is not conducive to environmental protection. Basalt fiber is a new type of inorganic fiber material with good performance. After the natural basalt rock is melte...

[0004] At the same time, due to the continuous reduction of fibers during the winding process and the vibration between the various mechanical systems, the tension during the winding process will not be constant. The quality of the entire fiber winding product has a great influence. If the tension between the fiber bundles is not equal when winding, the local fiber strength may be insufficient when subjected to external loads, which will affect the overall strength and cause damage to the winding product.
