Abstract

The invention relates to the making of multi layer knitting structure on the wire pulling glass steel tube using several computers controlling the two dimensional horizontal knitter, using core mold, stretch mold, extractor synthesizing the glass steel tube, setting resin dipping slot at the back of each knitter, even direct core mold at both ends of the core mold that follows with the movement of the ring knitting layer in the direction from the first two dimensional horizontal knitter to the last knitter through the dipping slot to the stretch mold. The glass tube in and out radius has high precision, thickness of each knitting layer adjustable, even in each dipping and consistent in strength.

Description

Technical field:

[0001] The invention relates to a method for preparing a glass steel pipe, in particular to a method for preparing a movable inner mandrel, a multilayer circular braid, and an online pultrusion multilayer circular braid structure and an online pultrusion glass steel pipe. Background technique:

[0002] At present, pultrusion is a widely used method for manufacturing FRP pipes. The method generally includes drawing multiple reinforcing fibers through a resin impregnation zone, and then pulling the impregnated fibers through a heated mold to solidify the resin and fibers. Together, the required glass steel pipe is formed. Since the pipe has only longitudinal unidirectional reinforcing fibers and only resin bonding force in the hoop direction, the bearing pressure is low. The pultrusion winding method is based on the pultrusion method. While pultruding, the longitudinal reinforcing fiber is hoop-wound, and then solidified by heating the mold. The glass steel pi...

Examples

Embodiment 1

[0023] Depend on figure 1 It can be seen that: the present invention adopts three computer-controlled two-dimensional horizontal braiding machines 1 to weave three-layer fiber annular braided layer composite glass steel pipes, and resin impregnation tanks 3 are arranged behind each braiding machine, and the third impregnation tank is arranged. Behind the groove is the pultrusion die 4; the core mold 1 is a uniform straight circular tube core mold with equal ends, the core mold is a mobile core mold that moves with the fiber annular braiding layer, and the core mold passes through the braiding machine and the dipping tank , the pultrusion die 4 moves with the horizontal movement of the drawn fiber by the drawing machine 5, by figure 1 It can also be seen that a storage tank 6 is installed above the dipping tank, and the storage tank communicates with the three dipping tanks through pipelines.

[0024] The operation process of the present invention is as follows: after the firs...
