Abstract
The invention discloses a method for manufacturing a variable-diameter conical composite insulator core pipe. A reinforcing material adopts equal-diameter glass fiber two-dimensional weaving sleeves. The method comprises the following steps of: according to the size of a composite insulator core pipe product, selecting the equal-diameter glass fiber two-dimensional weaving sleeves of corresponding specification, and cutting into the glass fiber two-dimensional weaving sleeves with the length which corresponds to the size of the composite insulator core pipe product; sleeving the weaving sleeves on a variable-diameter conical core mold, which is treated by a mold release agent, in a layered mode; applying tension to both ends of the weaving sleeves to make the weaving sleeves tensioned and tightly sleeved on the mold; sleeving the next layer of the weaving sleeve in the same mode, and controlling the number of layers of the weaving sleeves until the thickness is equal to the thickness of the product; by using a vacuum auxiliary dipping resin method, digging the glass fiber sleeves on the mold by resin; and curing, de-molding, cutting two ends to be flush with each other, and smoothly grinding the two ends to obtain the variable-diameter conical composite insulator core pipe. The variable-diameter conical composite insulator core pipe which is prepared by using the method is high in strength and uniform in wall thickness; secondary processing is not required; and production efficiency is improved.
Description
Technical field
The present invention relates to the manufacturing approach of the change diameter taper composite high voltage insulator core pipe that a kind of power industry uses.
Background technology
Power transmission and transforming equipment need use a large amount of insulators, and the insulator profile is various, isodiametric straight shape is arranged, become the taper of diameter and dolioform etc., adopts pottery, glass or Composite Preparation.Wherein, composite insulator light weight, moulding process are simple, have obtained application more and more widely.The preparation method of composite insulator core pipe or rod is various, and usually, small-bore composite material tube or rod adopts the pultrude process preparation, and bigbore composite core pipe adopts the winding process preparation more.In order to satisfy different instructions for uses, composite core pipe or rod be comprehensive kinds of processes preparation method also, and for example, patent CN200710019143.7 discloses a kind of dynamic vacuum impregnation pultrude process and prepared composite electric insulator core bar; Patent CN200510042803.4 discloses the preparation method with glass fiber impregnating resin wound-type composite insulator core; Patent CN 200610124731.2 discloses pultrude process and has combined winding, lay or rolling technology to prepare the method for composite electric insulator core bar.
Pultrude process is fit to the preparation of equal diameter composite electric insulator core bar, becomes diameter taper composite insulator structure plug but can not prepare; The change diameter composite insulator core pipe of winding process preparation, wall unevenness is even usually, must just can obtain waiting the composite core pipe of wall thickness through processing, both can cause the decline of its mechanical property, also can cause the waste of material.Main purpose of the present invention is to above-mentioned shortcoming, provides a kind of fibrage sleeve pipe that adopts to prepare the method that becomes diameter taper composite insulator core pipe as reinforcing material.
Summary of the invention
The purpose of this invention is to provide the fiberglass braided sleeve pipe impregnating resin of a kind of usefulness and prepare the method that becomes diameter taper composite insulator core pipe.
Realize that technical scheme of the present invention is: a kind of manufacturing approach that becomes diameter taper composite insulator core pipe, reinforcing material adopts isodiametric glass fiber control of two-dimensional braided sleeve pipe, and its manufacturing step comprises:
1) presses composite insulator core tubing products size, select the equal diameter glass fiber control of two-dimensional braided sleeve pipe of corresponding specification for use, be cut into and the corresponding length of composite insulator core tubing products size;
2) be enclosed within the braided sleeving layering on the change diameter taper core of handling through release agent, then the braided sleeving two ends applied tension force it is tightened up, and closely be enclosed within on the mould;
3) set by step 2) identical method cover one deck braided sleeving down, the number of plies of control cover braided sleeving reaches products thickness until thickness;
4) adopt vacuum-assisted impregnating resin method, make the glass fibre sleeve on the resin impregnation mould, be cured then, the demoulding, at last the two ends trimming is polished, promptly obtain becoming diameter taper composite insulator core pipe.
Wherein used resin comprises resin and curing systems such as epoxy resin, vinyl ester resin.
Because the two-dimensional fiber braided sleeving can change the angle θ direction of casing diameter size and fibre bundle within the specific limits through the degree of tightening up,, reach the purpose that becomes diameter therefore through tightening up braided sleeving.
The present invention compares with existing winding, rolling technology method, and reinforcing material is the continuous integral body of an equal thickness, and mechanical property is good and stable; Need not back processing, production efficiency is high, has reduced the waste of material loss simultaneously.

Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is the fiberglass braided sleeve pipe sketch map of equal diameter;
Fig. 2 is that fiberglass braided sleeve pipe becomes diameter typing sketch map;
Fig. 3 is a kind of change diameter taper hollow combined insulator core pipe sketch map that the present invention prepares.
Among the figure: the fiberglass braided sleeve pipe of 1-; The 2-mould.
Specific embodiment
Embodiment 1
A kind of change diameter taper hollow combined insulator size is as shown in Figure 3 to be divided into three sections: respectively there is one section equal diameter cylinder at two ends, and middle is taper.Goods total length 1500mm, large head external diameter
small head external diameter
wall thickness 10mm.Get fiberglass braided casing diameter
fibrage angle θ is 50 ° at present, the about 2.5mm of thickness.Preparation technology is following:
1) at first, intercepted length is fiberglass braided sleeve pipe four joints of 1600mm, and has sprayed release agent at the taper mandrel surface;
2) put the layer of glass braided sleeving from mould one end, and fixing, sleeve pipe to the tension of the mould other end, is made the braided sleeving mould that is locked, until consistent with each section of mould diameter;
3) set by step 2) identical method cover one deck braided sleeving down reaches the goods design thickness up to the thickness of braided sleeving, and is as shown in Figure 2.
At last, adopt vacuum-assisted technology to make glass fibre sleeve impregnating resin (glue), after curing, the demoulding two ends trimming is polished, promptly obtain becoming diameter composite insulator core pipe (as shown in Figure 3).
