Numerical Control of Fiberglass Pipe Bends Manufacturing

For urban water supply networks promising direction is the use of composite pipes with special properties, such as fiberglass. The characteristics of composite products are set by reinforcement schemes and the use of various binders. The stability of the strength characteristics significantly depends on the stability of the process of winding the reinforcing fibers. The kinematic scheme of the equipment realizes the rotation of the winding unit around the axis of the cross-section of the mandrel and the longitudinal-angular movement of the mandrel of the winding unit, which provides the possibility of cylindrical and spiral winding of the tape. The investigation of the nature of the variation in motion parameters for various programming methods has been carried out. The application of the developed equipment in the manufacturing of fiberglass bends is shown.
