Problems solved by technology

However, in this technical solution, the surface or inner surface of the spinneret is covered with a nano-scale or sub-nano-scale oxide film with a thickness of 0.8-28 μm, or a 0.1-0.25 mm oxide film is embedded in the spinneret hole of the spinneret. The processing technology of the thin metal layer is more complicated, and the processing cost is higher

Abstract

The invention discloses a spinneret orifice machining method of a spinneret plate. The spinneret orifice machining method comprises the following steps that S1, a plurality of punching horizontal position parts distributed in the length direction of a sharpening part are milled in the top position of the sharpening part prefabricated on a spinneret plate body by utilizing a milling cutter according to the preset position; S2, prefabricated through holes with the hole diameter slightly smaller than the preset diameter of spinneret orifices are drilled in the position of each punching horizontalposition part through a drill bit; and S3, extruding and chambering each prefabricated through hole one by one by using a chambering needle are carried out, so that the hole diameter of each prefabricated through hole is extruded and expanded to be matched with the preset diameter of each spinneret orifice to form the spinneret orifices, and a compact layer which is integrally formed with the inner wall of each spinneret orifice and can improve the hardness of the inner wall of each spinneret orifice is formed on the inner wall of each spinneret orifice. The spinneret orifice machining methodof the spinneret plate is simple, the production cost is low, the compact layer which is integrally formed with the inner wall of each spinneret orifice and can improve the hardness of the inner wallof each spinneret orifice is formed on the inner wall of each spinneret orifice, and the service life of the spinneret plate can be prolonged.

Description

technical field [0001] The invention relates to the technical field of spinnerets, in particular to a method for processing spinneret holes of a spinneret. Background technique [0002] The spinneret hole processing process of the existing spinneret is usually as follows: firstly position the spinneret body, then fix the point on the perforated flat part reserved on the spinneret body, punch holes to form the spinneret hole, and then Remove the spinneret body and clean it, then reposition the spinneret body and sharpen the flat part of the hole, after that, remove the spinneret body again and clean it, and then polish each nozzle by fluid polishing. The inner wall of the wire hole is polished and finally deburred. The hardness of the spinneret hole wall of the spinneret made by this processing method is not strong enough. In actual use, the service life of the spinneret is relatively short. Usually, the entire spinneret needs to be replaced with a new one in about two weeks...
