Abstract
The utility model discloses a multi-core ATA wire extruding device. The multi-core ATA wire extruding device comprises a parallel wire extruding machine head, wherein a core wire positioning head is arranged in a taper hole of the parallel wire extruding machine head; a core wire positioning nozzle is arranged at the back end of a core wire positioning head; and a ground wire positioning slot is formed in a core wire hole of the core wire positioning nozzle. The multi-core ATA wire extruding device changes the conventional sizing filling extruding way of the parallel wire extruding machine head into a 360-degree centralizing sizing extruding way and adds the core wire positioning head to the parallel wire extruding machine head to enwrap insulating wrapper; the pressure of the machine head and the rotation speed of a screw rod meet the requirement for maximum production capacity; an optimal value is obtained between the quality and the speed; and the ground wire positioning slot is formed in the core wire hole of the core wire positioning nozzle to effectively control tight adhesion between a ground wire and an aluminum foil, so that the phenomenon that the ground wire and the aluminum foil are separated to form a short circuit is avoided.
Description
Technical field
The utility model belongs to cable stranding technical field, relates to a kind of cable stranding technology, is specifically related to a kind of extrusion device of multicore ATA wire rod.
Background technology
Tradition ATA wire rod, as shown in Figure 1, after heart yearn 1 production is finished, adopt the flat cable head to extrude crust 4 again, when extruding, unwrapping wire uses the flat cable pay off rack, at coil holder and die orifice end through felt removing possible greasy dirt, and then pass through extrusion molding behind the internal mold coated insulation crust that location hole advances extrusion die.
But, when producing in batches, exist following deficiency for the extrusion way of this traditional flat cable formula:
1, because adopt traditional flat cable head to extrude insulation sheath 4, sizing material is after screw rod flows out, and without centerbody, but directly through the distribution runner of the interior cloth of heating sheet, from advancing glue perpendicular to the direction of extruding of heart yearn 1 wire rod.This mode because of the particularity of its structure, requires finished product ground wire 3 to contact with aluminium foil 2 for ATA class wire rod.And this delta hedge delta sizing material up and down is easy to cause ground wire 3 and aluminium foil 2 to separate, and the phenomenon of short circuit occurs.
2, based on the particularity of ATA wire rod structure, the wire rod extruded velocity is slow, and head pressure and screw speed can not satisfy the maximum output demand, must obtain optimum value between quality and speed, so whole linear speed only is 30 meters/minute.
3, mould is easy to wear: though the location is arranged when heart yearn 1 and ground wire 3 enter die orifice, because the unwrapping wire mode of flat cable is an inverted V-shape from back to front, therefore can cause the ground wire 3 pore volumes change easy to wear of mould big, cause the quality problems of wire rod moulding.
The utility model content
The purpose of this utility model provides a kind of extrusion device of multicore ATA wire rod, it will have flat cable extruder head mould now and directly pass through the extrusion way of the distribution runner of cloth in the heating sheet perpendicular to wire direction filling sizing material, change 360 degree gather extrusion way from plastic emitting to the center into, and install the heart yearn positioner additional and come the coated insulation crust, effectively controlled ground wire and aluminium foil fits tightly, ground wire and the phenomenon that aluminium foil separates short circuit can not occur, solve the problems referred to above that exist in the existing multicore ATA wire rod stranding technology.
The technical scheme that the utility model adopted is, a kind of extrusion device of multicore ATA wire rod, the flat cable extruder head that comprises extrusion device is equipped with a heart yearn positioning head in the taper hole of described flat cable extruder head, heart yearn location mouth is equipped with in the rear end of heart yearn positioning head.
The extrusion device of multicore ATA wire rod described in the utility model, its feature also be,
Described heart yearn location is provided with the ground wire location notch in the mouth heart yearn hole.
The extrusion device of the utility model multicore ATA wire rod, it will have the extrusion way of flat cable extruder head mould filling sizing material now, change 360 degree gather extrusion way from plastic emitting to the center into, and in the winding displacement extruder head, install the heart yearn positioning head additional and come the coated insulation crust, head pressure and screw speed have satisfied the output greatest requirements, obtain optimum value between quality and speed; And, effectively controlled ground wire and aluminium foil fits tightly by the ground wire location notch in the mouth heart yearn hole, heart yearn location, no longer occur ground wire when wire rod is extruded and separate the phenomenon that forms short circuit with aluminium foil.

Fig. 1 is existing ATA wire rod flat cable head extrusion die structural representation;
Fig. 2 is the extrusion device structural representation of the utility model multicore ATA wire rod;
Fig. 3 is the utility model heart yearn location mouth partial structurtes schematic diagram.
Among the figure, 1. heart yearn, 2. aluminium foil, 3. ground wire, 4. insulation sheath, 5. flat cable extruder head, 6. heart yearn positioning head, 7. heart yearn location mouth, 8. ground wire location notch.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
A kind of extrusion device of multicore ATA wire rod, as shown in Figures 2 and 3, comprise the flat cable extruder head 5 of extrusion device, be equipped with one 6 in the taper hole of described flat cable extruder head 5, heart yearn location mouth 7 is equipped with in the rear end of heart yearn positioning head 6, is provided with ground wire location notch 8 in the mouth 7 of described heart yearn location.
The extrusion device of the utility model multicore ATA wire rod, when wire rod is extruded, with three heart yearns 1 that coated aluminium foil 2 be equipped with from the rear end of heart yearn positioning head 6 heart yearn location mouth 7 pass, when ground wire 3 is close to aluminium foil 2 and is drawn by the ground wire location notch 8 of heart yearn location mouth 7, in the taper hole of flat cable extruder head 5, extrude insulation sheath 4 together, mold multicore ATA wire rod.
The extrusion device of the utility model multicore ATA wire rod, it will have vertically the annotate extrusion way of sizing material of flat cable extruder head mould now, change the extrusion way that gathers plastic emitting by winding displacement extruder 360 degree to the center into, and in winding displacement extruder head 5, install three heart yearns 1 that heart yearn positioning head 6 location coated aluminium foil 2 additional and come coated insulation crust 4, because the heart yearn location is provided with ground wire location notch 8 in the mouth 7 heart yearn holes, make ground wire 3 be close to aluminium foil 2, when in the taper hole of flat cable extruder head 5, extruding insulation sheath 4 together, ground wire 3 tightly fits together with the plastic emitting extruding that aluminium foil 2 is subjected to gather to the center, can not separate, the phenomenon that no longer occurs short circuit when therefore wire rod being extruded has improved the electric property of wire rod.
Above-mentioned execution mode is an example of the present utility model; not to be used for limiting enforcement of the present utility model and interest field; all equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
