Abstract
The utility model provides a special sheath mould of high altitude suspension type coaxial cable, includes extrusion molding mold core and extrusion molding die sleeve, the outstanding head of extrusion molding mold core is the toper structure, and outstanding head is equipped with main cable outlet and metal reinforcement outlet, main cable outlet and metal reinforcement outlet bear the footpath length and equal. Further, the extrusion molding die sleeve is nested and matched with the extrusion molding die core and is in an 8-shaped round hole structure; the connecting rib between the two holes in the shape of the '8' is provided with a tearing opening, the distance between the tearing opening and the edge of the main cable outlet is 0.38mm, and the width of the tearing opening is 0.4mm. The utility model has the advantages that the size of the connecting rib is fixed in the middle of the traditional self-supporting coaxial cable sheath layer, and a tearing opening and an R5 arc chamfer are added, so that the construction is convenient and the tearing is easy; the main cable and the metal reinforcing part can be easily separated, and the damage to the cable in the cable construction process is reduced; the lengths of the bearing diameters of the main cable outlet and the metal reinforcing part outlet are equal, the bearing diameter is equal to the designed relatively long bearing diameter, and the vibration of the metal reinforcing part and the main cable is reduced.
Description
(I) the technical field
The utility model relates to a cable mold specifically is a high altitude suspension type coaxial cable sheath mould.
(II) background of the invention
Traditional self-supporting coaxial cable product structural design is more common, and its structure comprises single cable and metal reinforcement, because its self characteristics, traditional cable has some problems when the construction.
Traditional structure self-supporting coaxial cable can not be light separation main push-towing rope and metal reinforcement, and traditional self-supporting coaxial cable is because the splice bar between main push-towing rope and the metal reinforcement is on the thick side to lead to in the construction, easily give the main push-towing rope when separating main push-towing rope and metal reinforcement and tear.
Disclosure of the invention
The to-be-solved technical problem of the utility model is that convenient construction easily tears. Not only can ensure that the main cable and the metal reinforcing part are easily separated, but also can reduce the damage to the cable in the cable construction process.
Therefore, the utility model adopts the following technical proposal:
the utility model provides a special sheath mould of high altitude suspension type coaxial cable, includes extrusion molding mold core and extrusion molding die sleeve, the outstanding head of extrusion molding mold core is the toper structure, and outstanding head is equipped with main cable outlet and metal reinforcement outlet, main cable outlet and metal reinforcement outlet bear the footpath length and equal.
Further, the extrusion molding die sleeve is nested and matched with the extrusion molding die core and is in an 8-shaped round hole structure; the connecting rib between the two holes in the shape of the '8' is provided with a tearing opening, the distance between the tearing opening and the edge of the main cable outlet is 0.38mm, and the width of the tearing opening is 0.4mm.
Furthermore, the connecting rib is designed in a conical shape, the width of one end of the connecting rib for connecting the main cable is 0.6mm, the connecting rib is provided with an R5 arc chamfer, and the width of one end of the connecting rib close to the metal reinforcing part is 0.8mm.
The utility model has the advantages that: the size of a connecting rib is fixed in the middle of a traditional self-supporting coaxial cable sheath layer, a tearing opening and an R5 arc chamfer are added, and the construction is convenient and easy to tear; the main cable and the metal reinforcing part can be easily separated, and the damage to the cable in the cable construction process is reduced; the lengths of the bearing diameters of the main cable outlet and the metal reinforcing part outlet are equal, the bearing diameter is equal to the designed relatively long bearing diameter, and the vibration of the metal reinforcing part and the main cable is reduced.
(IV) description of the drawings
FIG. 1 is a schematic sectional view of the structure of the present invention;
FIG. 2 is a cross-sectional view of the present invention;
FIG. 3 is a schematic view of the mold core;
fig. 4 is an enlarged schematic view at a.
(V) detailed description of the preferred embodiments
Referring to the attached figures 1-4, the special sheath die for the overhead suspended coaxial cable comprises an extrusion molding die core 3 and an extrusion molding die sleeve 4, wherein the protruding head of the extrusion molding die core is of a conical structure, a main cable outlet 3-1 and a metal reinforcement outlet 3-2 are arranged on the protruding head, and the lengths of the main cable outlet 1 and the metal reinforcement outlet 2 are equal. The extrusion molding die sleeve is nested and matched with the extrusion molding die core and is in an 8-shaped round hole structure; the connecting rib 4-1 between the two holes in the shape of the '8' is provided with a tearing opening 4-2, the distance between the tearing opening and the edge of the main cable outlet is 0.38mm, and the width of the tearing opening is 0.4mm. The connecting rib is designed in a conical shape, the width of one end of the connecting rib connected with the main cable is 0.6mm, the circular arc chamfer angle with R5 is 4-3, and the width of one end close to the connecting rib of the metal reinforcing part is 0.8mm.
In the production process, before the semi-finished main cable and the metal reinforcing piece go deep into the extrusion molding die, the main cable sequentially passes through a positioning device and a preheater; the metal reinforcing part is matched with the molds such as the positioning device and the straightening device in sequence to complete the whole production.
