Abstract
The invention discloses a technology for manufacturing an injection molding pole with a lining. An injection molding outer casing comprises accessories of a sleeve serving as the lining, an upper conductive element, a fixed end cover plate, a vacuum arc-extinguishing chamber, a movable fixed end cover plate, a lower conductive element and the like, and the sleeve can be used as the lining to solve contraction distortion of positions with inconsistent thicknesses on the outer casing. The technology has the advantages that a pre-fabricated sleeve is used as the lining in the pole, contraction distortion happening to the pole due to inconsistent thicknesses of the outer casing during injection molding can be solved, the surface of the outer casing is smooth, and simultaneously, the mechanical strength of the outer casing is enhanced.
Description
Technical field
The present invention relates to a kind of manufacturing technology of high-voltage vacuum circuit breaker polar post, especially relate to a kind of injection molding pole manufacturing technology.
Background technology
Pole is vacuum circuit-breaker and the outside vitals that is connected, it is the core component in the power switch cabinet, existing manufacturing technology begins to adopt the injection moulding mode to make pole, because the first half in the pole is embedded with vacuum interrupter, Lower Half is in order to want the separating/closing mechanism of mounting spring actuating, can leave the space less than vacuum interrupter, so the first half Thickness Ratio of pole shell is thinner, Lower Half thickness can be thicker, the Lower Half case surface of pole will produce serious contraction distortion like this, cause the surface to be uneven.
Summary of the invention
The objective of the invention is in order to solve the deficiency of above-mentioned technology, propose a kind of injection molding pole manufacturing technology that lining is arranged, when solving the manufacturing of injection molding pole, the surface at the inconsistent position of pole outer casing thickness will produce the technical barrier of serious contraction distortion.
The present invention is achieved by the following technical solutions: a kind of injection molding pole manufacturing technology that lining is arranged, the sleeve and the upper electric-conductor that comprise as lining are arranged in the shell of injection moulding, the fixed end cover plate, vacuum interrupter, the moved end cover plate, the accessories such as lower electric-conductor, it is characterized in that: described sleeve is to be made into prefabricated component with exotic material, as the lining in the shell Lower Half, the thickness of sleeve wall is decided by the needed space of spring actuating separating/closing mechanism that inside will be installed, the overall diameter of sleeve is to be determined by assurance shell wall thickness prerequisite unanimous between the higher and lower levels, the outer round surface of sleeve is provided with rugged groove, in order to increase the fastness of being combined with shell, in pole middle part and other positions, all have an inconsistent position of outer casing thickness, can solve contraction distortion as lining with sleeve.
Described sleeve selects resistant to elevated temperatures material to comprise the polytetrafluoroethylene of DMC material, SMC material, bakelite, plastics and PTFE alloy etc., adopts various conventional methods to make sleeves according to the material of selecting is different.
The material of described shell is selected high voltage withstanding engineering plastics, comprises PA66, or the PVDF Kynoar, or other can satisfy the engineering plastics of high voltage withstanding any trade mark.
Described shell injection molding technology, at first there are the vacuum interrupter of fixed end cover plate, moved end cover plate, lower electric-conductor and sleeve to put into respectively the correspondence position of polar pole die as inserts in upper electric-conductor, cover, carry out 110 ℃ of preheatings, plastic pellet with preheating is transported in the material storage jar subsequently, by a plunger.Plastic pellet in the material storage jar is injected in the mould, after injection moulding is complete, want pressurize, dwell time is finished to flow by plastic pellet and decides with the melting required time, being cooled under pressurize below 90 ℃ can the demoulding, to avoid in pole, producing bubbles of vacuum, pole after the demoulding is placed in 110 ℃ the baking oven again and anneals, the internal stress of freezing to discharge pole inside.
The invention has the beneficial effects as follows: utilize the prefabricated component sleeve as the lining in the pole, can solve the contraction distortion that pole produces because shell wall thickness is inconsistent when injection moulding, make case surface level and smooth, increase simultaneously the mechanical strength of shell.
