Multifunctional horizontal type aluminum wire enamelling machine

Abstract

The invention discloses a multifunctional horizontal type aluminum wire enamelling machine. The multifunctional horizontal type aluminum wire enamelling machine comprises a pay-off apparatus, a wiredrawing apparatus, a cleaning apparatus, an annealing furnace, a painting apparatus, a baking furnace, a cooling apparatus and a take-up apparatus. The multifunctional horizontal type aluminum wire enamelling machine provided by the invention is applicable to painting and processing of metal wires of various different core materials, particularly the aluminum wire; online wiredrawing is realized, so that aluminum wire wiredrawing and enamelling can be carried out at the same time; the pay-off apparatus tightly compresses and brakes the wire through soft wheels, so that a bare wire is in a tensioned state; after the aluminum wire is subjected to online wiredrawing, the aluminum wire is cleaned by an ultrasonic cleaning machine first to remove aluminum powder and lubricating grease on the surface; a wire supporting roller is arranged between the baking furnace and the cooling apparatus, so that friction between the aluminum wire and the pipe wall can be prevented; the cooling apparatus is used for forcedly cooling a high-temperature wire coming out of the baking furnace; the air flow direction in an air channel is opposite to the marching direction of the wire; the air is large in air volume and high in air speed, so that a sufficient cooling effect can be ensured; in addition, the take-up apparatus is provided with a constant-speed apparatus; a constant-speed wheel is equipped with a wire pressing wheel, so that the take-up speed is stable.

Description

technical field [0001] The invention relates to the technical field of enamelled wire production equipment, in particular to a multifunctional horizontal aluminum wire enamelling machine. Background technique [0002] The traditional process of making enamelled aluminum round wire includes paying off—(online wire drawing)—cleaning—softening—painting—baking—lubrication—rewinding. The finished bare wire produced in the previous wire drawing process (or the finished bare aluminum wire produced in the previous wire drawing process through unwinding and then the finished bare aluminum wire produced by the online wire drawing machine) enters the cleaning system to clean the oil slick on the surface of the bare wire And aluminum powder, enter the softening furnace for annealing, the soft wire formed by annealing passes through the drying system and then enters the painting system for painting and enters the oven for baking, repeats several times, and then passes through the lubrica...

AI Technical Summary

Problems solved by technology

[0003] In the production process of enamelled aluminum wire, the softening furnace is an important part of the equipment, which is provided by the equipment manufacturer. Generally, it consists of a number of stainless steel seamless tubes with a length of 6-9 meters and an inner hole of 16-20 mm. The main body is composed of an external electric heating tube, an external filling of asbestos and a metal protective cover. The above-mentioned softening furnace has the following disadvantages when producing aluminum enameled wire: the bare aluminum wire passes through the stainless steel tube during the production process, because the aluminum wire will become soft and fall after being heated. Unavoidable friction between the wire and the tube wall, limited to the characteristics of the bare aluminum wire itself, makes the surface damaged and hairy, and the injured aluminum wire directly affects the quality of the finished enamelled aluminum wire, such as lacquer bumps and lower breakdown voltage , the disconnection frequency remains high

Blocked softening tubes are difficult to clean and production needs to be stopped for cleaning

[0005] When the existing wire drawing device is working, the bare enameled wire will be tensioned to a certain extent. If the drawing speed is too fast, the bare wire will be stretched and thinned when the tension is relatively large, and it will be broken in severe cases, thus affecting to the quality of the finished line

To reduce the tension, the wire drawing speed must be adjusted. However, in the existing wire drawing device, the wire receiving fixed speed wheel and the wire drawing fixed speed wheel are installed at the two ends of the same shaft, and the wire receiving fixed speed wheel and the wire drawing fixed speed wheel are synchronized. Turning, no separate adjustment for drawing speed or take-up speed
