Description

A kind of multi-thread extrusion die

Technical field

This utility model relates to a kind of multi-thread extrusion die, belongs to electric wire extrusion equipment field.

Background technology

Society human cost improves constantly, and each side management cost rises steadily, and how to improve enterprises production efficiency, and it is necessary for lifting up high efficiency on identical manpower and materials basis.

The extrusion die used in the processing of present electric wire is made up of core rod and die sleeve, and core rod and die sleeve fit through respective string holes makes electric wire electricity extrude from mould. This extrusion die once can only extrude a wire cable, and production efficiency is low. This practicality green wood has only to a production line and can realize multi-thread producing simultaneously, is greatly improved production efficiency. But realizing this purpose to be likely to need the many places frock on production line to transform, original single line produces equipment can not be suitable for multi-thread extrusion.

Chinese patent CN201220431717.8 discloses the extrusion die in the processing of a kind of electric wire, it includes core rod and die sleeve, core rod is arranged on core rod seat, die sleeve is arranged on above die sleeve seat, core rod coordinates with die sleeve, core rod has two or more wire hole, die sleeve has two or more wire hole. But this extrusion die cannot regulate extrusion capacity in actual use, is easily caused the cable eccentricity of extrusion simultaneously.

Utility model content

This utility model aims to provide a kind of multi-thread extrusion die, and this multi-thread extrusion die can efficiently solve the cable eccentricity problem caused that die sleeve is eccentric.

To achieve these goals, this utility model be the technical scheme is that

A kind of multi-thread extrusion die, including the die sleeve being contained on die sleeve seat, is contained in the core rod on core rod seat; It is structurally characterized in that, described core rod and die sleeve matched in clearance, and the port of export at core rod has multiple wire hole, and the port of export at die sleeve has multiple wire hole, coordinates and connect between wire hole and the wire hole of die sleeve of this core rod; The anti-eccentric adjustable mechanism preventing die sleeve eccentric it is provided with between described die sleeve seat and die sleeve.

Thus, when, in actual production process, when die sleeve bias being detected, being then adjusted by anti-eccentric adjustable mechanism, thus what ensure electric wire goes out line mass.

According to embodiment of the present utility model, it is also possible to make this utility model further to optimize, the below technical scheme for being formed after optimizing:

Preferably, described anti-eccentric adjustable mechanism is at least four adjusting bolt, and the outside wall surface of described die sleeve is pressed in the end of each adjusting bolt traverse die sleeve seat and bolt. Thus, it is possible to ensure that the wire hole of core rod prevents bias with the wire hole center alignment of die sleeve.

For the convenient extrusion capacity that regulates in actual use, the entrance point of described core rod and die mandrel are fixedly linked, and be provided with and regulate the extrusion capacity governor motion in gap between core rod and die sleeve between this die mandrel and core rod seat. Preferably, described extrusion capacity governor motion includes being threaded the adjusting nut being connected to die mandrel one end, and the die mandrel adjusted is locked on core rod seat by described adjusting nut.

Preferably, the entrance point of described core rod is threadeded with die mandrel, thus, it is also possible to by regulating end of thread length of fit between core rod and die mandrel.

Preferably, the wire hole of described core rod and the wire hole of die sleeve are three holes. It is of course also possible to according to actual needs single line hole is transformed into two-wire hole, four string holes etc.

Compared with prior art, the beneficial effects of the utility model are:

1, using multi-thread extrusion cable mould can greatly save the cost such as human and material resources, management, on identical manpower and materials basis, theory can raise speed on original mould basis production efficiency at double. Such as producing RVV1.5mm²During plastic cord, if being 3m/s with original single line extrusion die starting up speed, after employing above-mentioned multi-thread extrusion cable mould, head is constant, material is constant, and personnel are constant, and after generally speaking changing original gel quantity when consuming constant exactly, speed of production just can reach 3*3m/s, increase exponentially production efficiency, directly bring more economic benefit for employee more enterprise.

2, the multi-thread extrusion die of holes, four holes or more porous can also be acted on except three punch dies illustrated, but must have the corresponding matched use of porous die sleeve.

3, multi-thread extrusion core rod simply makes a change at outlet mode with die sleeve, and screw thread mouth size is consistent with single line extrusion die, it is not necessary to redesigns, has virtually saved manpower and the time of designer.

4, because screw socket structure is consistent with single line extrusion die, so selected head is also identical with single line extrusion die, it is to avoid because of the equipment loss that frequent replacing head brings.

5, three holes or above porous extrusion die, die sleeve aspect can also continue to use before old mould modify increase aperture, both saved again time of processing and fabricating and cost turn avoid the waste of material, reached again the effect of recycling. Because the reason of structural design can not add work again, multi-thread extrusion die uses core rod aspect.

Below in conjunction with drawings and Examples, this utility model is further elaborated.

Detailed description of the invention

A kind of multi-thread extrusion die of cable, as Figure 1-3, including the die sleeve 1 being contained on die sleeve seat 3, is contained in the core rod 2 on core rod seat 4; Described core rod 2 and die sleeve 1 matched in clearance, the port of export at core rod 2 has multiple wire hole 9, and the port of export at die sleeve 1 has multiple wire hole 8, coordinates and connect between wire hole 9 and the wire hole 8 of die sleeve 1 of this core rod 2;Core rod is arranged on die mandrel by screw thread mouth, and die mandrel is contained on core rod seat, controls the spacing between core rod and die sleeve by adjusting nut. Die sleeve is arranged on above die sleeve seat, upper four adjusting bolts of die sleeve seat, is possible not only to fixing die sleeve by adjusting bolt, it is also possible to eccentric adjustment. Core rod and die sleeve cooperate, and are provided with three wire holes on core rod, corresponding with three wire holes on die sleeve, center alignment each other, so can be achieved with carrying out multi-thread production with equipment simultaneously.

As a kind of concrete concrete structure regulating die sleeve 1 degree of eccentricity, being provided with at least four adjusting bolt 6 between described die sleeve seat 3 and die sleeve 1, the outside wall surface of described die sleeve 1 is pressed in the end of each adjusting bolt 6 traverse die sleeve seat 3 and bolt. Thus, it is possible to ensure that the wire hole of core rod prevents bias with the wire hole center alignment of die sleeve.

In order to conveniently regulate extrusion capacity, the entrance point of described core rod 2 is threadeded with die mandrel 5, and one end of this die mandrel 5 is equipped with adjusting nut 7, and the die mandrel 5 adjusted is locked on core rod seat 4 by described adjusting nut 7.
