With Six Sigma Manufacturing Process Method Of Enameled Wire Quality Analysis

In the manufacture of enameled wire process, general requirements for various lengths of the products in different period of time once completed. In the manufacturing process of continuous very hard. In a continuous manufacturing process difficult through destructive testing to test the quality of the product, usually when discovering a problem, have produced a batch of defective products. So we need to process special control. This article through to the6Sigma DMAIC Define Measurement Analysis Improvement Control) method research, applied to the wire manufacturing process, which can control the stability of product quality and consistency.Based on the basic principle of six sigma method and DMAIC mode on the content of study, aiming at the production characteristics of the enameled wire industry-how in the DMAIC process definition phase of the proposed effective measures to gain the customer demand.In defining and measuring stage, I plant through statistical data, analysis of enameled wire manufacturing process quality character data type, identify the withdrawal line rate is influenced by the quality of enameled wire the main reason of the problem, after further statistical analysis, identified the winding adaptability, particle, breakdown voltage, high pressure continuous film bad adverse effects of annealing line rate is the key factor.The analysis and improvement of phase, for winding adaptability, we focus on the elongation and enameled wire surface lubrication modification, make use of the two approximation of a curve reflects the compression ratio and elongation of the relationship, so we by controlling the compression ratio for the control of elongation, enameled wire surface lubrication, we redesign the lubricating device structure, formulate the corresponding process documents, operator training, implementation and supervision to guarantee, we introduced from abroad the lubricant coating device, adopts the advanced coating process. For particles and film continuity problems, we analyzed the reasons of impurity particles, improvement, and the use of on-line particle detecting instrument to test the effect of improvement, eventually obtained using high-quality copper rod and method of multi-pass painted on the bubble type of particles as well as the film continuity has improved significantly conclusion. For the problem of breakdown voltage, we pass on the breakdown voltage of the mechanism were analyzed, the experiment, the experimental data statistics, using two regression regression analysis, summed up the film thickness is the main factors influence the breakdown voltage.During the control phase, research on statistical process control theory and methods used in the manufacture of enameled wire process, establish relevant documents, and effective training of every staff, to ensure that they are able to correctly understand and implement it, according to the6Sigma project achievement, on the impact of process output each the key variable in accordance with the method of continuous measuring.
