Abstract
The invention provides an external layer aluminum foil longitudinal covering die for a three-shielding coaxial cable. The external layer aluminum foil longitudinal covering die comprises a die body, wherein an inlet and an outlet are arranged at two opposite ends of the die body; a longitudinal covering hole section of which the aperture is gradually reduced is arranged on the die body in the direction from the inlet to the outlet; a forming stabilizing device is also arranged on one side, corresponding to the outlet, of the die; the forming stabilizing device comprises a main body and a through hole, wherein the through hole is communicated with the outlet, and the through hole has the same aperture as the outlet. According to the aluminum foil longitudinal covering forming die provided by the invention, a longitudinal covering forming stabilizing area is designed, therefore, the aluminum foil can be used for covering stably and flatly, and is hardly damaged, and the roundness of the aluminum coil after the longitudinal covering is improved, and the benefits are brought to improve the echo level and the transmission quality of products; compared with traditional longitudinal covering die, the external layer aluminum foil longitudinal covering die provided by the invention achieves the integral design of the aluminum foil longitudinal covering and stable forming, thus, the operation can be conveniently and simply carried out, and is easily controlled; and the production efficiency and the yield of the products are greatly improved.
Description
(1) technical field
The present invention relates to the vertical bag mould of a kind of three screened coaxial cable production process ectomesoderm aluminium foils.
(2) background technology
The basic composite construction of physical blowing cable TV three screened coaxial cable outer conductors is: internal layer aluminium foil vertical bag (ground floor)+aluminum-magnesium alloy wire braiding vertical bag of (second layer)+outer foil (the 3rd layer), the vertical bag of outer foil all is integrated finishing when litzendraht wire is produced sheath at present basically, in coaxial knitting process, outer foil is carried by guide wheel, enter mould for longitudinal wrapping of aluminium foil in company with sheath, then take sheath as the axle center, coat sheath.Existing mould for longitudinal wrapping of aluminium foil includes an inlet and an outlet, the hole that described entrance and exit successively decreases by the aperture is communicated with, behind the vertical bag of aluminium foil from the outlet of mould out, stable molding behind the not vertical bag, directly enter in the back to back extrusion head, therefore, the stability of the vertical wrap molding of aluminium foil often causes eliminating the bad phenomenon such as " initial line ", fold, the ovality of aluminium foil be poor not.
(3) summary of the invention
In order to solve the shortcoming that exists when the vertical bag of above-mentioned three screened coaxial cable outer foils is produced, the invention provides the vertical bag mould of a kind of three screened coaxial cable production process ectomesoderm aluminium foils, when producing, the vertical bag of outer foil can greatly improve the stationarity of aluminium foil cabling and coating, the vertical bag of strict control direction, and can effectively strengthen the compactness of aluminium foil and braiding, aluminium foil and sheath coating, the bad phenomenon such as " initial line ", fold after having eliminated outer foil and coating, ovality are poor have improved echo level and the up-to-standard rate of product.
For this reason, the present invention takes following technical scheme:
A kind of three screened coaxial cable outer foil longitudinal covering model tools, include mold, corresponding two ends of described mold are provided with entrance and exit, be provided with the vertical bag hole that a sector hole directly successively decreases along entrance to Way out on the described mold, the corresponding outlet of described mold one side also is provided with the stable molding device, described stable molding device includes body and through hole, and described through hole is communicated with outlet, and the aperture of described through hole is consistent with the aperture of outlet.
Further, described body and mold are one-body molded.
Further, the height of described body be the mold height 1/3rd ∽ two/
Employing the present invention have the following advantages: 1, the vertical wrap molding mould of Novel aluminium foil, be designed with a vertical wrap molding stable region, so that aluminium foil coats and more stablizes smoothly, be not easy to sustain damage, improve the roundness level behind the vertical bag of aluminium foil, be conducive to improve product echo level and transmission quality; 2, compare with existing longitudinal covering model tool technology, owing to realized the integrated design of the vertical bag of aluminium foil and stable molding, so that easy to operate simple, easy to control, production efficiency and product percent of pass improve greatly.
(4) description of drawings
Fig. 1 is overall structure schematic diagram of the present invention;
Wherein, 1-entrance, 2-outlet, 3-through hole, 4-body, 11-mold, the vertical bag of 12-hole;
Fig. 2 is the mould of the present invention explanation schematic diagram that makes a practical application of a principle;
Wherein, 5-double plate aluminum foil pay-off device, 6-carriage, 7-aluminium foil direction control guide wheel, 8-mould for longitudinal wrapping of aluminium foil of the present invention.
(5) embodiment
The present invention is described further below in conjunction with specific embodiment:
With reference to accompanying drawing 1,2, a kind of three screened coaxial cable outer foil longitudinal covering model tools, include mould, 11, corresponding two ends of described mold are provided with entrance 1 and outlet 2, are provided with the vertical bag hole 12 that a sector hole directly successively decreases along entrance to Way out on the described mold, the corresponding outlet of described mold one side also is provided with the stable molding device, described stable molding device includes body 4 and through hole 3, and described through hole is communicated with outlet, and the aperture of described through hole is consistent with the aperture of outlet.Described body and mold are one-body molded.The height of described body is 1/3rd of mold height.
During the practical operation of the vertical bag of aluminium foil, aluminium foil is pulled from aluminum foil pay-off device 5, adjust suitable direction by aluminium foil direction control guide wheel 7 on the carriage 6 and enter three screened coaxial cable outer foil longitudinal covering model tools 8, aluminium foil strictly is coated to control the litzendraht wire outside according to the direction that designs in mould, after the stable molding, enter in the back to back extrusion head.
Use mould of the present invention and use conventional apparatus application contrast table as follows: wherein, 1#, 2# embodiment adopt mould of the present invention, and 3#, 4# then adopt traditional easy device.
By the above-mentioned actual result of the test of implementing, can find out, after having used mould of the present invention, the apparent planarization of the aluminium foil behind the sheath has obtained obvious improvement, occur without " initial line " phenomenon, and Effective Raise the whole echo level of product, production efficiency also improves greatly, the operation simple and convenient is welcome by the operating personnel very.
