Description
Technical field
The utility model belongs to film lapped wire manufacturing technology field, is specifically related to a kind of manufacturing equipment of film lapped wire.
Background technology
Film lapped wire, traditional manufacturing process are wrapped 1 to 3 strata tetrafluoroethene films outside bare copper wire, get into high temperature furnace then, make the polytetrafluoroethylene film and the copper conductor of outside be bonded to one, then cooling curing.But, when carrying out around-packing technology, regulate loosely when no matter film is wrapped or tight, between insulation film band and bare copper wire surface, always there is certain gap, retain the condition created for steam and air.Especially in adjacent insulation film lap-joint, be the space of more steam and air trapping.Near this space, the difference of oxygen concentration and the effect of moisture film have formed the electrochemical corrosion of oxygen concentration cell, generate in lap-joint and transform more CuO; So in lap-joint; Be the film lapped wire part of turning black the most easily, and should the surperficial black film in place thicker, color is also darker.In addition, because the existence of oxygen, can be when high-temperature baking, oxidation takes place and makes its blackout in direct and bare copper wire surface.
Film lapped wire conductor blackout to the performance of electrical equipment with no small influence is arranged useful life, once took place a lot ofly to cause the electrical equipment user to reject the dispute of lapped wire because of the electromagnetic wire conductor turns black.Therefore, solve lapped wire conductor blackout problem significance is arranged.
Solve film lapped wire conductor blackout at present and mainly contain following dual mode: before (1) is wrapped, come starvation, thereby stop conductor oxidized at the conductive surface coating protective film; The oxidation inhibitor of this kind arts demand excellent performance, the higher and remaining diaphragm of technological requirement can influence the combination property technical indicator of film lapped wire; (2) around-packing technology is carried out under the condition of vacuumizing; This technology exists when vacuumizing, owing to always there is the oxygen of certain surplus, still can make the lapped wire conductor turn black, and just degree is lighter, and the vaccum-pumping equipment investment is expensive, and production cost is higher.
The utility model content
The purpose of the utility model provides that a kind of structure is comparatively simplified, cost is lower, effectively solves the manufacturing equipment of the film lapped wire of conductor black-emitting technology problem.
The technical scheme that realizes the utility model purpose is: a kind of manufacturing equipment of film lapped wire comprises pay off rack, wrapping mechanism, high-temperature baking baking oven and rolling frame; It is characterized in that: also comprise the closed box that is provided with conductor import, film import, blank outlet and air inlet, said wrapping mechanism is arranged in the closed box.
In the such scheme, said high-temperature baking baking oven is provided with blank import and air inlet.
The utlity model has positive effect: (1) the utility model is provided with one to have the bare copper conductor import, treats the closed box around film import, the outlet of lapped wire blank and air inlet, and wrapping mechanism is wherein built-in; During use; Treat to be wrapped in the process that becomes the lapped wire blank on the bare copper conductor feasible on the wrapping mechanism around film; All the time the air inlet from casing charges into inert gas; And inert gas is discharged from conductor import, film import, blank outlet, make to be in the inert gas shielding state in the closed box; The feasible in this way no longer oxygenous and steam in the lapped wire blank that obtains, thus conductor black-emitting technology problem effectively solved, the utility model is compared with legacy equipment in addition, and structure is comparatively simplified, cost is lower.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Be labeled as shown in the accompanying drawing: closed box 1, conductor import 11, film import 12, blank outlet 13, air inlet 14, wrapping mechanism 2, conductor 3 is treated around film 4, high-temperature baking baking oven 5, blank import 51, air inlet 52, pay off rack 7, rolling frame 8.
Embodiment
(embodiment 1, manufacturing equipment)
Fig. 1 is a kind of structural representation of the utility model, has shown a kind of embodiment of the utility model manufacturing equipment.
Present embodiment is a kind of manufacturing equipment of film lapped wire, comprises pay off rack 7, wrapping mechanism 2, high-temperature baking baking oven 5, rolling frame 8 and closed box 1.Said closed box 1 is provided with the closed box 1 of conductor import 11, film import 12, blank outlet 13 and air inlet 14, and said wrapping mechanism 2 is arranged in the closed box 1.
Said high-temperature baking baking oven 5 is provided with blank import 51 and air inlet 52.
(application examples 1, manufacturing approach)
Should use-case be to adopt embodiment 1 said manufacturing equipment to make a kind of embodiment of film lapped wire, see Fig. 1, may further comprise the steps:
1. be provided with and one have bare copper conductor import 11, treat that wrapping mechanism 2 is wherein built-in around the closed box 1 of film import 12, the outlet 13 of lapped wire blank and air inlet 14;
2. let bare copper conductor 3 get into casing 1 from the conductor import 11 of closed box 1; Let and treat to get into casing 1 from film import 12 around film 4; And becoming the lapped wire blank on the bare copper conductor 3 making on the wrapping mechanism 2 to treat to be wrapped in around film 4, said lapped wire blank exports high-temperature baking baking oven 5 to from the blank outlet 13 of casing 1; In this process, the air inlet 14 from casing 1 charges into inert gas all the time, and inert gas is discharged from conductor import 11, film import 12, blank outlet 13, makes to be in the inert gas shielding state in the closed box 1;
3. in high-temperature baking baking oven 5, the lapped wire blank is carried out high temperature sintering and handle, and in the high temperature sintering processing procedure, in high-temperature baking baking oven 5, feed inert protective gas, make to be in the inert gas shielding state in the said high-temperature baking baking oven 5; To its cured of lowering the temperature, wait to solidify the back rolling then as film lapped wire finished product.
In should use-case, said inert gas be a nitrogen, and direction shown in the arrow is the nitrogen air supply direction among the figure.
In should use-case, said high-temperature baking baking oven 5 be provided with blank import separately 51 and air inlet 52, and the nitrogen in the high-temperature baking baking oven 5 mainly is from air inlet 52, to get into.
To adopting the film lapped wire sampling analysis of above-mentioned application examples 1 preparation, the result shows the outer surface light of film below copper conductor, does not have stain.
In sum, the utility model can make the no longer oxygenous and steam in the lapped wire blank that obtains, thereby effectively solves conductor black-emitting technology problem, and the utility model is compared with legacy equipment in addition, and structure is comparatively simplified, cost is lower.
