Abstract
A mould pressing insulator manufacture method comprises the steps of adding vulcanized parachute tray glue into a squeezing machine to be squeezed into an epoxy glass fiber rod, and placing the epoxy glass fiber rod into a vulcanizing mould. The formed epoxy glass fiber rod is formed by adding a high temperature vulcanized silicon rubber layer outside the epoxy glass rod, the high temperature vulcanized silicon rubber layer outside the epoxy glass rod is mould pressed into a parachute tray strand, mould pressing vulcanization forming time is 3 to 5 minutes, and mould pressing vulcanization temperature is 150 +/- 10 DEG C. The mould pressing insulator manufacture method saves using amount of raw materials, solves the problem of adhesion interface between the parachute tray and a protection sleeve, meet requirements for high temperature resistance of the epoxy glass fiber rod in an injection process and shortens vulcanization time. The mould pressing insulator manufacture method reduces raw material cost, remarkably shortens form time and eliminates adhesion interface between the parachute tray and the protection sleeve. A mould is low in manufacture cost, simple in structure and convenient to operate.
Description
Technical field
The present invention relates to a kind of manufacture method of composite insulator.
Background technology
At present, extensive composite insulator production has two kinds of techniques, the one, squeezing bag penetrating umbrella technique, the 2nd, integral injection molding technique.The step of squeezing bag penetrating umbrella technique is: 1) the epoxy glass fiber rod extrudes moulding-high temperature vulcanized moulding, 2) umbrella disk compression molding-post-cure, 3) wear umbrella, 4) fitting assembly-crimping, and 5) the normal temperature sealing, 6) draw examination-high voltage test-packing.The step of integral injection molding technique is: 1) fire resistant epoxy Fiber glass rod preheating, 2) umbrella disk alters injection moulding, 3) fitting assembly-crimping, 4) the normal temperature sealing, 5) draw examination-high voltage test-packing.Between the first technique epoxy glass fiber rod sheath and the umbrella disk bonding interface is arranged, the stub difficulty extrudes, and waste is large, and production process is many.The second technique injection cure time is long, must the high fire resistant epoxy Fiber glass rod of use valency.
Summary of the invention
The object of the invention is to overcome the defective that exists in the existing technique, a kind of moulded insulator manufacture method that can improve the production efficiency of low-voltage-grade composite insulator is provided.
Manufacture method of the present invention comprises:
To vulcanize umbrella disk glue and add extruding machine, and extrude moulding epoxy Fiber glass rod, the epoxy glass fiber rod of moulding increases temperature the sulphurated siliastic layer for the expoxy glass mandrel outer;
Above-mentioned epoxy glass fiber rod is put into the high-temperature silicon disulfide rubber layer compression molding umbrella disk string that sulfurizing mould makes the expoxy glass mandrel outer, and the molded vulcanization molding time is 3 ~ 5 minutes, 150 ± 10 ° of C of molded vulcanization temperature.
Described sulfuration umbrella disk glue is high-temperature silicon disulfide rubber.
Described manufacture method also comprises: before will vulcanizing umbrella disk glue adding extruding machine, according to low-voltage-grade used in composite insulator glue amount, select to extrude the shape of the mouth as one speaks.
The described shape of the mouth as one speaks that extrudes is the sizing material forming frock by steel-blank system.
The present invention's use amount that can not only save material solves the bonding interface between umbrella disk and the sheath, and has solved in the injection technique the resistant to elevated temperatures requirement of epoxy glass fiber plug, shortens cure time.The present invention can reduce the cost of raw material, in the time of significant shortening forming time, eliminates the bonding interface between umbrella disk and the sheath.Mould is cheap, and is simple in structure, easy to operate.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is process chart of the present invention.
Fig. 2 is the plug band sizing material figure after extruding among Fig. 1.
Among the figure, 1, the expoxy glass plug, 2, high-temperature silicon disulfide rubber.
Embodiment
Among Fig. 1, Fig. 2, the present invention includes: 1) according to low-voltage-grade used in composite insulator glue amount, select to extrude the shape of the mouth as one speaks.Extrude the shape of the mouth as one speaks and be the sizing material forming frock by steel-blank system, what design caliber size with sizing material according to goods.2) will vulcanize umbrella disk glue (take methyl vinyl silicone rubber as base material, add multiple Inorganic Chemicals through the mixing elastomeric compound that forms) the adding extruding machine, extrude moulding epoxy Fiber glass rod, the epoxy glass fiber rod of moulding adds 2 layers of high-temperature silicon disulfide rubbers for expoxy glass plug 1; 3) above-mentioned epoxy glass fiber rod is put into sulfurizing mould and made expoxy glass plug 12 layers of compression molding umbrella disk of high-temperature silicon disulfide rubber string outward, reach the elimination bonding interface, shortening forming time, the purpose of the reduction cost of raw material.The molded vulcanization molding time is 3 ~ 5 minutes, 150 ± 10 ° of C of molded vulcanization temperature.Molded vulcanization molding time of the present invention was lacked 8 to 10 minutes than existing injection molding technique required time.
