Description

Doubling die for aluminum alloy stranded wire production

Technical Field

The utility model belongs to the technical field of stranding equipment, and particularly relates to a stranding die for producing aluminum alloy stranded wires.

Background

In the stranded wire production process, the aluminum alloy wire needs to be formed by using a doubling die. In the use process, the conventionally used doubling dies all adopt arc chamfer wire inlets, the wire inlets are easy to embed aluminum scraps and aluminum powder, and after the aluminum scraps and the aluminum powder are accumulated in an enrichment mode, the wire inlets can be directly contacted with the surface of a wire in a stranded wire channel directly to cause the surface quality damage of the wire, and the wire can be scrapped in serious cases.

SUMMERY OF THE UTILITY MODEL

In view of the defects described in the prior art, the utility model provides a doubling die for producing an aluminum alloy stranded wire, wherein the structure of a wire inlet of the doubling die is changed, so that the doubling die can contain aluminum scraps and aluminum powder and is not contacted with the surface of a stranded wire.

The technical scheme adopted by the utility model is as follows:

a doubling die for producing aluminum alloy stranded wires comprises a doubling die body, wherein the doubling die body is provided with a doubling channel, a conical auxiliary stranded wire channel and a scrap stacking channel are arranged at a wire inlet of the doubling channel, the conical auxiliary stranded wire channel is communicated with the scrap stacking channel and the doubling channel, and the inner diameter of the conical auxiliary stranded wire channel is gradually reduced from the scrap stacking channel to the doubling channel; a step structure is formed between the debris accumulation channel and the conical auxiliary stranded wire channel. The space that aluminium powder, the aluminium bits that the stair structure regarded as reserving gathered, can be fine keep apart aluminium powder aluminium bits and wire, prevent that the aluminium powder aluminium bits of enrichment directly contacts with the wire in the doubling passageway, avoid stranded conductor surface damage.

As a preferable scheme of the utility model, the depth of the debris accumulation channel is not less than the diameter of a single wire of the wire, so that aluminum powder and aluminum debris are isolated from the wire.

As a preferable scheme of the utility model, the axes of the conical auxiliary stranded wire channel, the debris accumulation channel and the doubling channel are overlapped, and the structure can ensure that the doubled conductor cannot be bent.

According to the utility model, the wires to be stranded penetrate from the scrap accumulation channel and then enter the conical auxiliary stranded wire channel, the conical surface of the conical auxiliary stranded wire channel guides and restrains the single wires of the wires, so that the single wires of the wires to be stranded smoothly enter the stranded wire channel to be stranded, and the step structure is used as a reserved space for gathering aluminum powder and aluminum scraps, so that the aluminum powder and aluminum scraps can be well isolated from the wires, the gathered aluminum powder and aluminum scraps are prevented from directly contacting the wires in the stranded wire channel, and the damage to the surface of the stranded wires is avoided.
