Can find out that it is earlier each part to be made moulding, and then fits together.Owing to be simple fitting together, its bonding strength can't guarantee.
Summary of the invention
The objective of the invention is the problems referred to above, provide a kind of simple in structure, the pole that strength ratio is higher to the prior art existence.
Another object of the present invention is to have above-mentioned problem to existing pole manufacture method, and the manufacture method of the pole that a kind of processing technology is simple, production cost is low, the finished product rate is high is provided.
First purpose of the present invention can realize through following technical proposal: a kind of manufacture method of pole; Pole comprises insulating cylinder body, goes up conduction connector, vacuum interrupter and following conduction connector; Said insulating cylinder body one end seals an other end opening, and above-mentioned vacuum interrupter is connected in the blind end of insulating cylinder body, and last conduction connector is connected in the insulating cylinder body blind end and the one of which end links to each other with vacuum interrupter; The other end stretches out insulating cylinder body; Above-mentioned conduction connector down is connected in the insulating cylinder body middle part and the one of which end is positioned at the insulating cylinder body outside, and the other end is positioned at insulating cylinder body inside, and this manufacture method may further comprise the steps:
A, part connect: will go up conduction connector and vacuum interrupter links together through securing member;
B, dress mould: will descend conduction connector, the last conduction connector that links together and vacuum interrupter, and be complementary locating piece one, the locating piece two bigger of insulating cylinder body openend inboard than insulating cylinder body openend size put into the forming cavity between upper die body and the lower mold body; One end of above-mentioned locating piece one is resisted against the end opposite that vacuum interrupter and last conduction connector link; The other end of locating piece one is resisted against on the locating piece two; Above-mentioned down conduction connector is resisted against locating piece one top, in last conduction connector, vacuum interrupter, conduction connector, locating piece one, locating piece two and formation and insulating cylinder body are complementary between the die body up and down mold cavity down;
C: upper and lower conduction connector location: will go up conduction connector through fixture and be fixed on upper die body or the lower mold body, will descend conduction connector to be fixed on same upper die body or the lower mold body through the another one fixture;
D: casting: with the nylon material of fusion with obtain the liquid of casting after glass fiber material fully mixes according to weight ratio 1:0.5-1.5, have the tapping hole that communicates with mold cavity bottom the lower mold body, above-mentioned casting liquid is in tapping hole injection mold cavity;
E: the demoulding: after treating the moulding of 4-16 hours casting liquid at normal temperatures; Upper die body is separated with lower mold body; Then fixture is separated with last conduction connector, the another one fixture is separated with following conduction connector, obtain pole behind dismounting locating piece one and the locating piece two.
At first will go up conduction connector and vacuum interrupter is fixed together through securing member, then in company with conduction connector, locating piece one and locating piece two are together put into the forming cavity between upper die body and the lower mold body down.Certainly, go up conduction connector, vacuum interrupter, conduction connector, locating piece one, locating piece two and the mold cavity that forms between the die body up and down and insulating cylinder body is complementary down after above-mentioned various piece places.To go up conduction connector in this process and fix, and avoid in casting cycle, moving with following conduction connector.
After the nylon material of fusion and glass fiber material fully mix according to the weight ratio of setting, inject above-mentioned mold cavity from the bottom to top by the tapping hole of the lower mold body bottom liquid of will casting.Certainly, through sources of the gas such as air pumps casting liquid is carried in this process.After liquid to be cast solidifies, upper die body and lower mold body are split, remove locating piece simultaneously once obtaining the pole finished product with locating piece two.
In the manufacture method of above-mentioned pole, the securing member in the said steps A is a screw.
Can make conduction connector and firm the linking together of vacuum interrupter through screw.
