Device used for producing flat transposed aluminium conductor and provided with transposition device

Abstract

The invention relates to a device used for producing a flat transposed aluminium conductor and provided with a transposition device, which mainly comprises two parts: a device main body and the transposition device, wherein the device main body comprises a positioning shaft, an adjusting shaft sleeve, a connecting shaft sleeve, a fixed shaft, a stranding cage main shaft and a stranding cage; the transposition device comprises a shaping die, a die holder, a pressing cover and a positioning tongue; the positioning shaft of the device main body is in screwed connection with the adjusting shaft sleeve behind the positioning shaft; the front end of the positioning shaft is in screwed connection with the positioning tongue arranged in the transposition device; the positioning tongue is matched with the shaping die arranged on the die holder, and the pressing cover is arranged at the upper end of the shaping die; the vertical surface on one wire inlet side of the die holder is vertical to the central line of the positioning shaft; the positioning shaft is coincided with the central line of the stranding cage main shaft; and the shaping die installed on the die holder and the positioning tongue are coincided with the central line of the positioning shaft. By adopting the device, the running speed and product quality of a flat transposed aluminium conductor production line can be effectively improved, the labor intensity of operators is reduced, and the device is particularly suitable for mass production.

Description

technical field [0001] The invention relates to an electromagnetic wire production equipment, in particular to an equipment for producing flat transposed aluminum conductors equipped with a transposition device. Background technique [0002] At present, the flat transposed aluminum conductor is a new product developed by the magnet wire industry in recent years, and the reactor wound with this product has been successfully applied in the ultra- and extra-high voltage transmission lines of my country's power grid. The flat transposed aluminum conductor is a rectangular transposed aluminum conductor that is regularly arranged in multiple layers by transposing, shaping and pressing a plurality of round aluminum wires wrapped with film insulation. The formed wire is wrapped continuously in multiple layers with insulating film and composite film. The key technology of this product is the transposition of the wires. The existing transposition method is to rotate the twisted cage,...

Problems solved by technology

The key technology of this product is the transposition of the wires. The existing transposition method is to rotate the twisted cage, and drive the transposition die on the transposition device through the transmission shaft to perform forced transposition and pressing on all single conductors in production. ; This transposition method will cause great damage to the film-insulated round aluminum wire, affect the insulation strength between single wires, and easily cause problems such as wire jumping and misalignment; and it is difficult for workers to operate, the labor intensity is high, and the production efficiency is very low. Can not meet the needs of market development
