To achieve the goals above, the technical solution adopted by the present invention is that: rigid insulation connector manufacturing method, step
Are as follows:
1) right flange, is wound type glass reinforced plastic processing: the right flange that machining is completed, in its flange convex edge and
Flange root is wound the processing of type glass reinforced plastic, completes turning after solidification；
2) dress housing and right flange, are dried:, will using insulating joint mounting plate after externally set is heated and kept the temperature
Right flange, which is put into housing, is cooled to room temperature, and housing and right flange root winding-type glass reinforced plastic is made to form interference fit；
3), will dry dress after housing and right flange be sequentially placed into the O-ring seal of right flange, the O-ring seal of Zuo Falan,
Left flange, presses on press machine, by left flange and housing circumferentially 4 spot welding；
4) left flange and housing are welded into one by, destressing.
Turning dimensional tolerance is φ XX in the step 1)+0.3 +0.2, outer casing internal diameter dimensional tolerance with matching
For φ XX0 —0.1。
It is externally covered in the step 2) according to the size of housing and is heated and kept the temperature, 120 DEG C ± 2 DEG C of heating temperature；
Soaking time: outer diameter D≤φ 80mm keeps the temperature 30 ± 5min；80 < D≤φ 150mm of outer diameter range φ, heat preservation 45 ±
5min；150 < D≤φ 350mm of outer diameter range φ keeps the temperature 70 ± 5min；350 < D≤φ of outer diameter range φ
550mm keeps the temperature 90 ± 5min；Size range D > φ 550mm keeps the temperature 120 ± 5min.
Right flange is put into housing using 15 DEG C of water coolings to room temperature in the step 2).
5.0MPa pressure is imposed to left flange on press machine in the step 3), generates O-ring gapless pre-
Clamp force.
Left flange and housing circumferential weld are welded into one with filling weldering in the step 4).
The beneficial effect of the invention is: the invention provides a kind of rigid insulation connector manufacturing method, first
Right flange is wound the processing of type glass reinforced plastic, then dries dress housing and right flange, later by circumferentially 4 points of left flange and housing
Left flange and housing are welded into one by spot welding, last destressing.The method of the present invention is assembled using dress technique is dried, then is made outer
Set is cooling and right flange winding-type glass reinforced plastic is linked together；Winding-type glass reinforced plastic twines compared with filling cured epoxy resin
Geometric pattern glass reinforced plastic not only has electrical insulating property, but also improves mechanical strength, and brittleness is small, toughness is high, and crisp after epoxy resin cure
Property is big, toughness is small.So housing and right flange winding-type glass reinforced plastic are combined together with baking dress technique and both meet electric insulation
Property, mechanical strength, the requirement for also greatly improving insulating joint bending resistance square performance, solve asphalt mixtures modified by epoxy resin existing in the prior art
The technical problem of poor sealing performance and insulation performance difference caused by brittleness is big after rouge solidifies, toughness is small.
Detailed description of the invention
Fig. 1: for the structural schematic diagram of the invention.
Wherein, the right flange of 1-, the right flange root winding-type glass reinforced plastic of 2-, 3- housing, 4- felt pad, the right flange convex edge 5- twine
Geometric pattern glass reinforced plastic, 6- insulated enclosure gasket, 7-O type sealing ring, the left flange of 8-.
Specific embodiment
Rigid insulation connector manufacturing method, the steps include:
1, right flange is wound type glass reinforced plastic processing: the right flange 1 that machining is completed, in its flange convex edge and
Flange root is wound the processing of type glass reinforced plastic, completes turning after solidification.
2, dress housing and right flange are dried:, will using insulating joint mounting plate after housing 3 is heated and kept the temperature
Right flange 1, which is put into housing 3, is cooled to room temperature, and housing 3 and right flange root winding-type glass reinforced plastic 2 is made to form interference fit.
3, the housing 3 after filling will be dried and right flange 1 is sequentially placed into the O-ring seal of right flange, the O-ring seal of Zuo Falan
