Abstract
The utility model relates to a sizing mold for the production process of rubber-insulated fiber cables. The sizing mold conveys a cable core in fore-and-aft direction and comprises a main body; a guiding and positioning cavity communicating the front end surface and the rear end surface of the main body is formed in the main body; a cable core positioning channel for guiding and positioning the cable core in the conveying direction is formed in the middle of the guiding and positioning cavity; and the guiding and positioning cavity is provided with a first positioning channel and a second positioning channel, which are used for guiding and positioning corresponding tensile pieces in the conveying direction and arranged on two sides of the cable core positioning channel side by side. The utility model solves the problem in the prior art that the cable core and the two tensile pieces can not be positioned when passing a longitudinal wrap in an aluminum-plastic composite belt longitudinal wrapping mold.
Description
Technical field
The utility model relates to a kind of plug die that is used for the covered wire cable production run.
Background technology
Covered wire cable comprises cable core and two tensile members; In the production run of covered wire cable; Cable core there is not stranded parallel placement with two tensile members; Then cable core and two tensile members are indulged bag through doubling mould and aluminum plastic composite belt longitudinal bag mould successively, interior the offering along the cable core throughput direction of described doubling mould is used for cable core and two circular doubling chambeies that tensile members is passed through.The problem that prior art exists is: owing to lack the plug die to cable core and two tensile members, cable core and two tensile members can not be located in the process of vertical bag and swung constantly and reverse, and cause aluminum plastic composite belt longitudinal to contract out existing abnormity, have had a strong impact on product quality.
Summary of the invention
The purpose of the utility model is to provide a kind of plug die that is used for the covered wire cable production run, to solve cable core and two problems that tensile members can not be located in the prior art through the vertical bag of aluminum plastic composite belt longitudinal bag mould the time.
In order to address the above problem, the technical scheme of the utility model is:
A kind of plug die that is used for the covered wire cable production run; Carry the direction of cable core to be defined as fore-and-aft direction plug die; Comprise body; Offer the guide-localization chamber that connects the body front/rear end in the described body; The middle part in said guide-localization chamber is to be used for the cable core placed channel of cable core along the throughput direction guide-localization, and said guide-localization chamber is set side by side with in the both sides of said cable core placed channel and is respectively applied for first placed channel and second placed channel of corresponding tensile members along the throughput direction guide-localization.
The middle part of described cable core placed channel is a convex shape towards the cross sectional shape of first placed channel, one side; The middle part of described cable core placed channel is a convex shape towards the cross sectional shape of second placed channel, one side.
Described plug die has at least two and set gradually along fore-and-aft direction, and the guide-localization chamber of said different plug dies reduces or consistent along fore-and-aft direction perpendicular to the sectional area of its fore-and-aft direction gradually.
The beneficial effect of the utility model is: the utility model carried out guide-localization through plug die respectively to cable core and two tensile members before getting into corresponding aluminum plastic composite belt longitudinal bag mould; Restriction has also stoped the swing of cable core and two tensile members and has reversed; The rounding that has guaranteed aluminum plastic composite belt longitudinal jacket outward appearance is bright and clean, has improved production efficiency and product percent of pass.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment is as shown in Figure 1: a kind of plug die that is used for the covered wire cable production run; Carry the direction of cable core to be defined as fore-and-aft direction plug die; Comprise body 1; Offer the guide-localization chamber 6 that connects body 1 front/rear end in the described body 1; The middle part in said guide-localization chamber 6 is to be used for the cable core placed channel 3 of cable core along the throughput direction guide-localization, and said guide-localization chamber is set side by side with in the both sides of said cable core placed channel and is respectively applied for first placed channel 4 and second placed channel 5 of corresponding tensile members along the throughput direction guide-localization.
Further, the middle part of described cable core placed channel 3 is a convex shape towards the cross sectional shape of first placed channel, 4 one sides; The middle part of described cable core placed channel 3 is a convex shape towards the cross sectional shape of second placed channel, 5 one sides.The both sides of said body are respectively equipped with step mechanism 2.
Further, described plug die has two and set gradually along fore-and-aft direction, and the guide-localization chamber 6 of said different plug dies reduces (or consistent) perpendicular to the sectional area of its fore-and-aft direction along fore-and-aft direction gradually.
During use, this plug die is arranged at corresponding aluminum plastic composite belt longitudinal bag mould along the cable core throughput direction before, can also be according to the different numbers that relate to plug die flexibly of tensile members specification and material.Set up the tensile members high-carbon steel wire if adopt big specification metal; Because high-carbon steel wire hardness is big; Distortion is difficult, causes cable core to exist bigger internal stress to make the retrotorsion of cable core at aluminum plastic composite belt longitudinal bag bonding sheath for preventing once to be out of shape, and causes the sheath gross distortion; Can sizing be designed to twice (or three roads); Gap between guide-localization chamber and corresponding cable core and two tensile members reduces (or consistent) gradually, and wherein the first road plug die not only plays the guide-localization effect to cable core and two tensile members, but also plays also together the doubling mould effect of cable core and two tensile members.As adopt the nonmetal tensile members FRP that sets up of small dimension, then can only establish one plug die and get final product.
The utility model can be used for the production run of duct type service wire optical cable; The utility model carries out guide-localization with cable core and two tensile members; Eliminated the swing torsion phenomenon after duct type service wire optical cable core and two tensile members get into compound vertical bag mould, product first-time qualification rate and production efficiency improve greatly.
In other embodiment of the utility model, described upper and lower placed channel can also be the circle that has breach perpendicular to the cross sectional shape of its fore-and-aft direction; The road number of described plug die can also be four roads, five roads or multiple tracks.
