Embodiment 1

[0010] Place the pipe wall of the extruded unvulcanized rubber pipe fitting between the upper and lower molds having the same curvature as the rubber pipe fitting, the upper and lower molds are metal bodies with a heating cavity; Heat the upper and lower molds with steam, so that the rubber tube wall between the upper and lower molds is partially heated until initial vulcanization; then rotate the rubber tube and repeat the above process until the rubber tube is initially vulcanized; the rubber tube that has completed the initial vulcanization is placed in the vulcanization In the groove, the rubber pipe fittings are completely vulcanized through heat conduction through the heat medium in the groove.

Embodiment 2

[0012] Place the pipe wall of the extruded unvulcanized rubber pipe fitting between the upper and lower molds having the same curvature as the rubber pipe fitting, and the upper and lower molds are metal bodies with a heating cavity; The electric heating element in the machine heats the upper and lower molds, so that the wall of the rubber pipe fitting placed between the upper and lower molds is partially heated until it is initially vulcanized; after that, the rubber pipe is rotated to repeat the above process until the rubber pipe is initially vulcanized as a whole; the initial vulcanized rubber pipe will be completed Put it in the vulcanization tank, and conduct heat conduction through the heat medium in the tank to completely vulcanize the rubber pipe fittings.

Embodiment 3

[0014] The extruded unvulcanized rubber pipe wall is placed between the pair of rollers, and the pair of rollers is a metal body with a heating inner cavity; The pipe wall of the rubber pipe between the rollers is partially heated, and then the rubber pipe is rotated under the drive of the rollers, and the above process is repeated until the rubber pipe is initially vulcanized as a whole; the rubber pipe that has completed the initial vulcanization is placed in the vulcanization tank, and passed through The heat medium in the tank conducts heat conduction to completely vulcanize the rubber pipe fittings.

Abstract

Extruded rubber tube is set between upper and lower mold or between roller pairs with heating inner cavity for heating, so that the rubber tube is initially sulfurized locally; the rubber tube is then rotated and the local sulfurizing process is repeated to complete the initial sulfurization of the full rubber tube; and the initially sulfurized rubber tube is further heated in a sulfurizing tank for fully sulfurized. The said process needs no great diameter core mold, and this reduces the production cost greatly.

Description

Technical field: [0001] The invention relates to a vulcanization method for rubber pipe fittings, in particular to a method for segmentally vulcanizing rubber pipe fittings. Background technique: [0002] Existing vulcanization methods for rubber pipe fittings usually adopt the method of putting the extruded unvulcanized rubber pipe fitting on the mandrel for finalization, and then placing the unvulcanized rubber pipe fitting together with the mandrel in a heat vulcanization tank for overall vulcanization treatment. This traditional vulcanization method for rubber pipe fittings has simple process and high work efficiency, but the overall vulcanization of large-diameter rubber pipe fittings will greatly increase the production cost, because a corresponding large-diameter core mold and outer mold are required, which increases the cost of the core mold. , The amount of external mold consumables, processing costs and processing difficulty are not conducive to saving raw material...
