Description

Technical Field

[0001] The utility model relates to the technical field of tungsten wire drawing machines, in particular to a positioning device for tungsten wire drawing machines. Background Art

[0002] Tungsten wire drawing machine is a kind of equipment used to process tungsten material into filaments, usually used to manufacture tungsten wires, which are widely used in electronics, lighting and industrial fields. Tungsten wire drawing machine is usually equipped with a feeding system to provide tungsten blanks. After pretreatment, the tungsten blanks are fed into the wire drawing area of ​​the wire drawing machine. In the wire drawing area of ​​the wire drawing machine, the tungsten blanks are heated to a high temperature, usually above the melting point of tungsten. Subsequently, the tungsten blanks are gradually drawn into filaments through a series of wire drawing dies or tungsten wire drawing pliers. The drawn tungsten wire passes through a cooling system to quickly cool and solidify it to ensure the stability of the size and shape of the tungsten wire. The finished tungsten wire is rolled or wound onto an appropriate reel or plate for subsequent packaging, storage and transportation. Tungsten wire drawing machine plays a key role in the manufacturing process and provides an effective solution for the production of high-quality tungsten wire.

[0003] At present, in order to maintain the stability of the tungsten blank entering the wire drawing machine, a positioning device is generally set at the feed inlet of the wire drawing machine. However, the positioning effect of the positioning device at the feed inlet of the wire drawing machine is not ideal, which may cause the tungsten blank to shift during wire drawing, reducing the quality of wire drawing. Therefore, we propose a positioning device for tungsten wire drawing machine to solve the above problem. Utility Model Content
