Pressed stranded conductor stranding die for aluminum alloy cable

Abstract

The invention relates to a pressed stranded conductor stranding die for an aluminum alloy cable. The die comprises a die base, wherein the die base is internally provided with a pressed stranding die body, a compressed air ring and a compressed air inlet hole, and the pressed stranding die body comprises an outer layer die sleeve and a die core assembled in the die sleeve; a first channel of a pressed stranded conductor stranding wire is formed in the die core; the outlet of the first channel is connected with a second channel formed in the die sleeve; the compressed air ring is arranged on the outlet of the second channel, and a first set of air holes blowing air to the pressed stranding die body and a second set of air holes blowing air to a stranded conductor are formed in the compressed air ring. Due to the technical scheme, the first set of air holes and the second set of air holes in the compressed air ring perform cooling and pressure blowing around the stranded conductor and the pressed stranding die body, and therefore the filling density of the stranded conductor and the surface roughness of the conductor are improved, and meanwhile aluminum skimmings and aluminum powder generated in the spiral stranding pressing process and greasy dirt on the surface of an original alloy single wire are removed.

Description

technical field [0001] The invention relates to an aluminum alloy cable compactly stranded conductor stranding die. Background technique [0002] At present, most of the existing stranding machine mold bases use wooden molds to support the stranding molds. The wooden molds are often damaged during use. Different specifications of conductors use wooden molds of different specifications. The wire mold is tilted, which causes the conductor to be tight and twisted, which is not round enough, the production efficiency is low, and there are aluminum scraps, aluminum dust and oil stains on the conductor surface; at the same time, the cooling device of the mold seat of the existing stranding machine generally adopts the method of dripping industrial alcohol to twist The traditional method does not solve the effect of temperature rise on the mold and stranded wires. At the same time, aluminum chips will cause the insulation performance of the cable to decrease, and the insulation bre...
