Abstract
A core wire straightening die for an extruder comprises a base body, wherein a horizontal eccentric rod is arranged on the side surface of the base body, a rotary disc is arranged on the eccentric rod, a plurality of straightening holes with different apertures are circumferentially distributed on the rotary disc, and the straightening holes and a core wire in the base body are concentrically arranged after the rotary disc is attached to the base body; the utility model discloses a change between the whole straight hole of carousel realization need not loading and unloading and changes the mould, has improved the commonality, simple structure, low in production cost, convenient to use.
Description
Technical Field
The utility model relates to a cable manufacture's technical field specifically is a core wire straightening die utensil on with extruder.
Background
The cable and wire production process has a widely existed problem, and in the twisting process, the core wire is easy to twist due to inconsistent tension of each core of the multi-core wire or unstable tension of the whole multi-core wire. When the sheath is produced, the twisted core wire has various degrees of defects, the finished product is twisted, the skin is broken or the material is dead, and the like, and the trouble is brought to a certain degree in the processing process of a client. The straightening and twisting of the core wire are controlled by limiting the outer diameter before extrusion through a straightening die before the extrusion head. The existing mold has no universality, so that the corresponding mold needs to be replaced according to the diameter of the core wire on the same production line, and time and labor are wasted.
Disclosure of Invention
The utility model provides a with heart yearn straightening die utensil on the extruder, solved the problem that current mould does not have the commonality.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a core wire straightening die on extruder which characterized in that: the novel seat comprises a seat body, wherein a horizontal eccentric rod is arranged on the side face of the seat body, a rotary table is arranged on the eccentric rod, a plurality of straightening holes with different apertures are circumferentially distributed on the rotary table, and the straightening holes and core wires in the seat body penetrate through the cavity to be concentrically arranged after the rotary table is attached to the seat body.
The technical scheme is further limited, a positioning pin is arranged on one end face of the base body, opposite to the rotary table, a plurality of pin holes are circumferentially distributed on the rotary table, the pin holes can be in positioning fit with the positioning pin one by one, and the straightening holes on the rotary table can be arranged concentrically with the core wires in the base body through the positioning pin and the pin holes one by one; the structure is simple, the operation is convenient, and the rapid positioning is realized.
The technical scheme is further limited, an annular permanent magnet is arranged on one end face of the base body, which is opposite to the rotary disc, and the iron rotary disc is attached to the base body through the permanent magnet; the magnetic attraction area is increased by the annular permanent magnet, the fastening stability is ensured, and the rapid mounting and dismounting are facilitated.
Has the advantages that: the utility model discloses a change between the whole straight hole of carousel realization need not loading and unloading and changes the mould, has improved the commonality, simple structure, low in production cost, convenient to use.

Detailed Description
As shown in fig. 1 and 2, a core wire straightening die for an extruder comprises a base body 1, wherein a horizontal eccentric rod 2 is arranged on the side surface of the base body 1, namely, one end of the eccentric rod is welded with the base body, a rotatable turntable 3 is arranged on the eccentric rod, eight straightening holes 301 with different apertures are circumferentially distributed on the turntable, and the straightening holes on the turntable and the core wire in the base body are concentrically arranged after the turntable is attached to the base body;
as shown in fig. 1 and 2, a positioning pin 102 is arranged on one end face of the seat body opposite to the rotary table, eight pin holes 302 are circumferentially distributed on the rotary table, the eight pin holes can be positioned and matched with the positioning pins one by one, and the straight holes on the rotary table can be arranged concentrically with the core wire penetrating cavity in the seat body one by one;
as shown in fig. 1 and 2, an end surface of the seat body opposite to the turntable is embedded with an annular permanent magnet 103, and the iron turntable is attached to the seat body through the permanent magnet.
Instructions for use: as shown in fig. 3, the seat body can be connected with the inlet end of the mold core in the head of the extruder 4 by welding or screwing. Pulling the rotary table to separate the rotary table from the seat body; rotating the straightening holes on the rotary table according to the diameter of the core wire to enable the corresponding straightening holes to correspond to the core wire penetrating cavities in the seat body; the turntable is pushed, the positioning pin on the base body is inserted into the pin hole on the turntable and automatically fastened through the permanent magnet, and the straightening hole on the turntable and the core wire passing cavity in the base body are concentrically arranged, namely, the axis of the core wire hole in the die core, the axis of the core wire passing cavity in the base body and the axis of the straightening hole on the turntable coincide; the moving core wire 5 passes through the straightening hole to realize straightening, and the aperture of the straightening hole is consistent with the diameter of the core wire; in order to avoid scratching the wire core, a chamfer part is arranged at the port of the straightening hole; when the straightening holes need to be replaced, the conversion among the straightening holes is realized by rotating the rotary table, and the die does not need to be assembled and disassembled for replacement.
The details not described in the present specification are conventional in the art.
Claims (3)
