High-precision circular knitting machine part production process

Abstract

The invention discloses a high-precision circular knitting machine part production process. The production process comprises the following steps that an inner needle cylinder blank and a plurality ofouter needle cylinder blanks which can be fixed and are fully distributed on the outer side wall of the inner needle cylinder blank are machined; threaded holes are machined in the inner side walls ofthe outer needle cylinder blanks, and connecting holes corresponding to the threaded holes are machined in the inner needle cylinder blank; the outer needle cylinder blanks are fixed; the outer sidewalls of the outer needle cylinder blanks are machined until the outer side walls of the outer needle cylinder blanks are full of needle grooves; and the plurality of machined outer needle cylinder blanks are fixedly connected to the inner needle cylinder blank together to form a needle cylinder. Through the process, the needle cylinder is machined, when the needle grooves in the outer surface ofthe needle cylinder are damaged in the working process, the outer needle cylinder blanks can be replaced according to the damaged positions, the whole needle cylinder does not need to be abandoned, and environmental protection and reliability are better achieved; and during machining, the situation that the whole needle cylinder fails to be machined and is abandoned due to the fact that errors occur in machining of a certain needle groove is avoided, and the machining error-tolerant rate is high.

Description

technical field [0001] The invention relates to the field of knitting machinery, in particular to a production process for accessories of a high-precision circular weft machine. Background technique [0002] Large circular knitting machines are widely used in the existing knitting machines. Large circular knitting machines have many knitting systems, high speed, high output, pattern change block, good fabric quality, less process, and strong product adaptability, so they develop rapidly. The needle cylinder in the large circular knitting machine is a very important accessory. The function of the needle cylinder is mainly to fix the knitting needles for the large circular knitting machine and drive the knitting needles to work; Needle grooves are cut on the surface, because large circular knitting machines have high requirements on the accuracy of the needle grooves, often in the process of cutting needle grooves, slight vibrations may lead to the scrapping of the entire need...

[0002] Large circular knitting machines are widely used in the existing knitting machines. Large circular knitting machines have many knitting systems, high speed, high output, pattern change block, good fabric quality, less process, and strong product adaptability, so they develop rapidly. The needle cylinder in the large circular knitting machine is a very important accessory. The function of the needle cylinder is mainly to fix the knitting needles for the large circular knitting machine and drive the knitting needles to work; Needle grooves are cut on the surface, because large circular knitting machines have high requirements on the accuracy of the needle grooves, often in the process of cutting needle grooves, slight vibrations may lead to the scrapping of the entire needle cylinder, and if the existing needle cylinder is in use If the wear of individual needle grooves is serious, the entire needle cylinder needs to be replaced, which is not environmentally friendly.
