an air knife

Abstract

The invention discloses a novel air knife. The novel air knife comprises an air box with an air inlet, the air box is provided with a first line passing opening and a second line passing opening which are oppositely formed, the novel air knife is characterized in that a line passing guide pipe is arranged in the air box in a penetrating manner, the two ends of the line passing guide pipe are mounted in the first line passing opening and the second line passing opening correspondingly, and a plurality of inclined holes not perpendicular to the central axis of the line passing guide pipe are formed in the wall of the line passing guide pipe; the line passing guide pipe is arranged in the air box in the penetrating manner, the multiple inclined holes not perpendicular to the central axis of the line passing guide pipe are formed in the wall of the line passing guide pipe, the conditions that line passing sleeves are arranged in two line passing openings of an air box of a traditional air knife, and due to exhausting of the two line passing opening, the gas using amount is large are avoided, meanwhile, the difficult line passing problem is solved, and the air knife is simple in structure, saves resources and has the wide applicability.

Description

technical field [0001] The invention relates to the field of metal wire drawing, in particular to an air knife. Background technique [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 , the air knife is generally used to scrape oil on the steel wire, the traditional air knife such as figure 2 As shown, the air box 1' is included, and the air box 1' is provided with an air inlet and two opposite wire-passing ports, and the wire-passing port is installed with a wire-passing sleeve 2'. The air knife with this structure has the problem of difficulty in threading. , and the exhaust is carried out at the two wire passage ports, the gas consumption is large and the oil scraping quality is not high. ...
