A production process of high-precision circular weft machine accessories

Abstract

The invention discloses a production process of high-precision circular weft machine accessories, comprising the following steps: processing an inner needle cylinder blank and a plurality of outer needle cylinder blanks that can be fixed and covered on the outer side wall of the inner needle cylinder blank; A threaded hole is processed on the inner side wall of the inner cylinder blank, and a connecting hole corresponding to the threaded hole is processed in the inner syringe blank; the outer syringe blank is fixed; the outer wall of the outer syringe blank is processed until the outer wall of the outer syringe blank The needle groove is full; multiple processed outer needle cylinder blanks and inner needle cylinder blanks are fixedly connected together to form a needle cylinder; the needle cylinder processed by this process, when the needle groove on the outer surface of the needle cylinder is damaged during the working process , the outer needle cylinder blank can be replaced according to the damaged area, and the entire needle cylinder does not need to be scrapped, which is more environmentally friendly and reliable; during processing, the entire needle cylinder will not be scrapped because of an error in the processing of a certain needle groove, which will cause the processing failure of the entire needle cylinder, High processing error tolerance.

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] Among the existing knitting machines, circular knitting machines are widely used. The circular knitting machines have many loop-forming systems, high rotational speed, high output, pattern change blocks, good fabric quality, few processes, and strong product adaptability, so they have developed rapidly. The needle cylinder in the circular knitting machine is a very important accessory. The function of the needle cylinder is mainly to fix the knitting needle for the circular knitting machine and drive the knitting needle to work; the existing circular knitting machine is processed for the outer needle cylinder blank. The needle groove is cut on the surface, because the large circular knitting machine has high requirements on the precision of the needle groove, often in th...

Problems solved by technology

[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.
