Forming method and device of high-precision circular knitting machine work drum

Abstract

The invention discloses a forming method of a high-precision circular knitting machine work drum. The forming method of the high-precision circular knitting machine work drum comprises the following steps that (1) rough turning is carried out on a blank work drum; (2) fine turning is carried out on the blank work drum after rough turning to form a needle-groove-free work drum; (3) groove milling is carried out on the outer surface of the needle-groove-free work drum; (4) a needle groove formed in step (3) is polished to remove burrs; and (5) the needle groove of the work drum is inspected to determine whether the work drum is qualified or not. The invention further discloses a forming device of the high-precision circular knitting machine work drum to operate the step (3) and the step (4);first, a plurality of grooving devices arranged, around a bearing base, in a grooving forming device simultaneously perform grooving on the work drum, a polishing device immediately follows the grooving devices for fine polishing, the polishing device performs fine polishing on the needle groove when the grooving is carried out, and the problems of low production efficiency, insufficient precision and high scrap rate of existing work drums are solved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a high-precision circular knitting machine needle cylinder molding method and molding equipment. Background technique [0002] At present, with the continuous development of society, the development of the knitting industry is getting faster and faster. Among them, the large circular knitting machine is now used in many textile industries. The large circular knitting machine has many looping systems, high speed, high output, fast flower shape change, and fabric quality. Good, few processes, strong product adaptability, so it develops rapidly, and the needle cylinder in the large circular knitting machine is very important. The main function of the needle cylinder is to fix the knitting needles for the large circular knitting machine and drive the knitting needles to work. The needle groove is an indispensable part of the needle cylinder. The existing needle groove is sl...
