Efficient automatic forming method for needle cylinder of large-diameter circular knitting machine

Abstract

The invention discloses an efficient automatic forming method for a needle cylinder of a large-diameter circular knitting machine. The efficient automatic forming method comprises the following steps:processing out an inner needle cylinder blank and a plurality of outer needle cylinder blanks which can be fixed and are fully distributed on the outer side wall of the inner needle cylinder blank; processing out a threaded hole in the inner side wall of the outer needle cylinder blank, and processing out a connecting hole corresponding to the threaded hole in the inner needle cylinder blank; splicing the plurality of outer needle cylinder blanks into an annular outer needle cylinder blank main body, and fixing the outer needle cylinder blank main body; processing the outer side wall of the outer needle cylinder blank body till needle grooves are fully distributed in the outer side wall of the outer needle cylinder blank body; and fixedly connecting the processed outer needle cylinder blank body to the processed inner needle cylinder blank body together; When the needle grooves in the outer surface of the needle cylinder are damaged, the outer needle cylinder blank can be replaced according to a damaged position, and he whole needle cylinder does not need to be scrapped, and thus, the method is more environmentally friendly and reliable; in addition, an error-tolerant rate of processing the whole needle cylinder is increased by processing the outer needle cylinder blanks, so that the situation that the whole needle cylinder is scrapped due to processing errors is avoided.

Description

technical field [0001] The invention relates to the field of knitting machinery, in particular to a high-efficiency and automatic molding method for a needle cylinder of a large circular knitting machine. Background technique [0002] Large circular knitting machines are widely used in the textile industry. Large circular knitting machines have many knitting systems, high speed, high output, flower shape changes, good fabric quality, less processes, and strong product adaptability, so they develop rapidly. In large circular knitting machines, The needle cylinder is very important. The function of the needle cylinder is mainly to fix the knitting needles of the large circular machine and drive the knitting needles to work; most of the existing needle cylinder processing is to cut the needle groove on the outer wall of the needle cylinder blank at one time, and cut the needle groove Sometimes due to the shaking of the cutting device or the unstable fixing of the needle cylinde...

[0002] Large circular knitting machines are widely used in the textile industry. Large circular knitting machines have many knitting systems, high speed, high output, flower shape changes, good fabric quality, less processes, and strong product adaptability, so they develop rapidly. In large circular knitting machines, The needle cylinder is very important. The function of the needle cylinder is mainly to fix the knitting needles of the large circular machine and drive the knitting needles to work; most of the existing needle cylinder processing is to cut the needle groove on the outer wall of the needle cylinder blank at one time, and cut the needle groove Sometimes due to the shaking of the cutting device or the unstable fixing of the needle cylinder, the cutting of individual needle grooves is incomplete, resulting in the scrapping of the entire needle cylinder, which is a waste of raw materials; the processing of needle cylinders through this processing technology has a very high error tolerance rate. the small
