Abstract
The invention discloses a winding production process of a heavy-calibre glass fiber reinforced water feed pipe. The winding production process comprises the following steps of: (1) manufacturing a winding mold, wherein the outside diameter of the winding mold is equal to the inside diameter of the water feed pipe; (2) driving the winding mold to rotate by taking an axis of the winding mold as a rotating axis, driving the winding mold to move back and forth relative to an extruder in the axial direction of the winding mold, and winding a plastic inner layer of the water feed pipe on the periphery wall of the winding mold by utilizing the plastic extruder; (3) winding a glass fiber reinforced layer on the periphery wall of the plastic inner layer of the water feed pipe; (4) winding a plastic outer layer on the periphery wall of the glass fiber layer by utilizing the plastic extruder; and (5) cooling and demolding. The water feed pipe is produced by direct winding on the winding mold, so that the water feed pipes with various calibres can be produced as required; and the glass fiber layer is wound in the water feed pipe, so that the water feed pipe can obtain better internal pressure resistance under a thinner pipe wall condition, and the ring stiffness can meet the design requirement.
