Air knife device

Abstract

The invention discloses an air knife device, which comprises an air box and a pipe. The air box is provided with an air inlet. The upper and lower ends of the pipe extend out of the air box from the wire outlet and the wire inlet respectively. A stopper is fixed on the outer wall of the pipe and located at the upper end of the air box. A tightening block is provided on the outer wall of the pipe and located at the lower end of the air box. Air holes are provided, and the air holes are arranged in three rows, and the included angle between two adjacent rows of air holes is 120°, and vertical grooves are arranged on the inner wall of the pipe and opposite the air holes. The air knife unit facilitates threading and reduces the amount of lubricating oil falling into the air box.

Description

Technical field [0001] The present invention relates to the field of wire drawings, and more particularly to air knife devices. Background technique [0002] During the process of metal wire, it is often necessary to apply lubricating oil on the surface of the steel wire to reduce the friction between the wire and the brigadier. After the finishing process is completed, the lubricating oil on the surface of the steel wire needs to be cleaned, in the prior art Generally, the steel wire is used to scrape the steel wire, and the air inlet and two opposing over-line ports are provided on the air box. The over-line port is installed, and the air knife of this structure has a larger problem, And the two overlightelets are exhausted, with a large amount of gas, and the quality of the water is not high. Second, the lubricating oil scraped from the wire will fall into the air box, it is difficult to clean. Inventive content [0003] It is an object of the present invention to provide an ...

Problems solved by technology

[0002] In the process of metal wire drawing, it is usually necessary to apply lubricating oil on the surface of the steel wire to reduce the friction between the steel wire and the wire drawing die. After the wire drawing process is completed, the lubricating oil on the surface of the steel wire needs to be cleaned. In the prior art Generally, an air knife is used to scrape oil on the steel wire, and an air inlet and two opposite wire-passing ports are set on the air box, and a wire-passing sleeve is installed at the wire-passing port. The air knife with this structure has the problem of difficulty in threading. In addition, the two wire passages are exhausted, which consumes a large amount of air and the oil scraping quality is not high

Secondly, the lubricating oil scraped off the wire will fall into the air box, making it difficult to clean
