Abstract

The invention provides a manufacturing process of a connector for chinlon spinning engineering. The manufacturing process includes the following steps that blanking is conducted through a sawing machine; rough turning is conducted on a blank; a semi-finished product is hardened and tempered; the outer circle is subjected to rough turning and finish turning, drilling is conducted, and a sealing groove is machined; grooving, boring and rough turning of a conical surface are carried out; a positioning hole is drilled; through holes and a counter bored hole are drilled; a saw-tooth thread is machined, and finish turning is conducted on the conical surface; part of the thread is removed, and the head and tail of the thread are milled; pin holes are drilled, and polishing is conducted; nitrogen treatment is conducted; and pins are knocked in. According to the manufacturing process of the connector, the production efficiency is high, the production quality is stable, the accuracy is high, and the product quality is good.

Description

technical field [0001] The invention relates to a manufacturing process of a joint used in nylon spinning engineering. Background technique [0002] In the nylon spinning process, the spinning box is composed of a melt distribution pipe, a metering pump, and a spinning assembly. The melt filtered by the filter enters the spinning box. The spinning box is a rectangular heat carrier heating box, which is equipped with melt distribution pipes, metering pumps and components, and is covered with heat insulating materials to keep the melt warm. At present, the manufacturing process used in the market for the joints in the PA66 assembly of the spinning beam cannot be industrialized, the production efficiency is low, and the production quality is not stable enough. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide and improve production efficiency. [0004] To achieve the above object, th...
