Abstract
The utility model discloses a kind of hollow combined insulator with split flange, including insulation mandrel, flange and silicon rubber umbrella, described insulation mandrel two ends crimp flange respectively, and described silicon rubber umbrella is coated on insulation mandrel, and the two ends of silicon rubber umbrella are crimped on flange respectively；Described flange is made up of base and cylinder, and described cylinder is fixed in base.Because flange of the present utility model can be produced directly using steel plate and round steel, its shape is identical with the flange of original monoblock type, it is processed due to the round steel suitable with flange base diameter need not be chosen in its process, and only need to the selection round steel suitable with cylinder diameter and be processed, the raw material of more than half can be saved, the process time of half is also saved simultaneously, improves production efficiency.Flange of the present utility model is fully able to meet the antitorque mechanical requirements of the normal bending resistance of hollow combined insulator, and by inspection of dispatching from the factory, properties meet the requirements.
Description
Technical field
The utility model is related to the manufacturing technology of composite insulator, and particularly a kind of Hollow Compound with split flange is exhausted
Edge.
Background technology
Insulator plays two basic roles in overhead transmission line, that is, support wire and prevent electric current from going back to ground, and this two
Individual effect must be guaranteed, insulator should not due to environment and electric load condition change caused by various electromechanical stress
And fail, otherwise insulator would not produce great effect, will damage use and the service life of whole piece circuit.
Hollow combined insulator is made up of insulation mandrel inner cylinder, flange and silicon rubber umbrella, and its flange is integral flange,
The diameter of flange base is more much larger than the diameter of flange cylinder, and existing flange manufacture method is using suitable flange base
Round steel, process overall flange, the flange so produced has good mechanical property, its mechanical property far beyond
The antitorque mechanical requirements of the normal bending resistance of hollow combined insulator.But such mode of production there is a problem of following：
1st, the cylinder of major diameter being processed into integral (type) flange can waste substantial amounts of material；
2nd, the cylinder of major diameter is processed into integral (type) flange needs process time more long.
Utility model content
To solve the above mentioned problem that prior art is present, the utility model will design one kind and can reduce production cost and improve
The hollow combined insulator with split flange of production efficiency.
To achieve these goals, the technical solution of the utility model is as follows：Hollow Compound insulation with split flange
Son, including insulation mandrel, flange and silicon rubber umbrella, described insulation mandrel two ends crimp flange, described silicon rubber respectively
Umbrella cover is coated on insulation mandrel, and the two ends of silicon rubber umbrella are crimped on flange respectively；Described flange is by base and cylinder
Body is constituted, and described cylinder is fixed in base.
Further, described cylinder is fixed in base by welding manner.
Further, described cylinder is connected through a screw thread mode and is fixed in base.
Further, described cylinder is drum, and the bottom of cylinder is located in base.
Further, described base is circumferentially provided with 4-8 connecting holes.
Further, described base is dorsad provided with central circular groove, the depth of circular trough on the surface of insulation mandrel
0.8-1.2mm。
Flange manufacture method of the present utility model is as follows：
Flange of the present utility model makes corresponding flat base using steel plate according to the shape of flange, is done above base
Go out the circular hole corresponding with cylinder external diameter, then round steel is processed into the cylinder of corresponding size, be put into the circular hole of base, then
Junction is fixed, is reached and the flange identical effect for processing.
Compared with prior art, the utility model has the advantages that：
1st, because flange of the present utility model can be produced directly using steel plate and round steel, its shape and original entirety
The flange of formula is identical, is processed due to that need not choose the round steel suitable with flange base diameter in its process, and only
The round steel for needing selection suitable with cylinder diameter is processed, and the raw material of more than half can be saved, while also saving half
Process time, improve production efficiency.Only this item improves the cost that can be saved close to half, accordingly also improves product
Profit.
Although the 2, flange mechanical property of the present utility model is not so good as integral (type) flange, it is fully able to meet Hollow Compound insulation
The antitorque mechanical requirements of sub normal bending resistance, by inspection of dispatching from the factory, properties meet the requirements.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is flange arrangement schematic diagram of the present utility model.
In figure：1st, insulation mandrel, 2, flange, 3, silicon rubber umbrella, 4, base, 5, cylinder.
Specific embodiment
The utility model is further described through below in conjunction with the accompanying drawings.As shown in Figure 1-2, with the sky of split flange
Heart composite insulator, including insulation mandrel 1, flange 2 and silicon rubber umbrella 3, the described two ends of insulation mandrel 1 crimp flange respectively
2, described silicon rubber umbrella 3 is coated on insulation mandrel 1, and the two ends of silicon rubber umbrella 3 are crimped on flange 2 respectively；It is described
Flange 2 be made up of base 4 and cylinder 5, described cylinder 5 is fixed in base 4.
Further, described cylinder 5 is fixed in base 4 by welding manner.
Further, described cylinder 5 is connected through a screw thread mode and is fixed in base 4.
Further, described cylinder 5 is drum, and the bottom of cylinder is located in base 4.
Further, described base 4 is circumferentially provided with 4-8 connecting holes.
Further, described base 4 is dorsad provided with central circular groove, the depth of circular trough on the surface of insulation mandrel 1
0.8-1.2mm。
The manufacture method of flange of the present utility model 2 is as follows：
Flange of the present utility model 2 makes corresponding flat base 4 using steel plate according to the shape of flange 2, on base 4
Side makes the circular hole corresponding with the external diameter of cylinder 5, then round steel is processed into the cylinder 5 of corresponding size, is put into the circle of base 4
In hole, then junction is fixed, reach and the identical effect of flange 2 for processing.
The utility model is not limited to the present embodiment, any equivalent concepts in the technical scope that the utility model is disclosed
Or change, it is classified as protection domain of the present utility model.
