Embodiment Construction
[0022] The present invention will be further described below with reference to specific embodiments.
[0023] The method for diagnosing the tightness of the steel wire in the bead wire drawing process of the present invention comprises the following steps:
[0024] 1. Collect each experimental data (interval value) representing the five fuzzy sets of "too loose", "loose", "suitable", "tight" and "too tight" on the universe of bead wire tension;
[0025] 2. On the domain of bead wire tension [0,100N], divide into equal interval intervals [0,2.5],[2.5,5],......,[95,97.5],[97.5,100 ]., to determine the median value of each equal interval interval 1.25, 3.75, ..., 96.25, 98.75; then count the frequency of the median value of each equal interval interval included in the experimental data interval value; then, fit and construct a representation of the bead Fuzzy Set of "Too Loose" State of Steel Wire during Steel Wire Drawing

The invention relates to the technical field of steel wire drawing in mechanical engineering, in particular to a method for diagnosing the steel wire tightness state in a tire bead steel wire drawingprocess. The method comprises the following steps that 1, on the tension discourse domain of the tire bead steel wire, the steel wire tightness state is determined and represented; 2, fuzzy sets representing the steel wire tightness state during drawing of the tire bead steel wire is established; 3, by means of a tension testing device, during tire bead steel wire drawing, the tension of the steelwire is measured, and then a fuzzy possibility distribution function representing the tension of the steel wire during tire bead steel wire drawing is established; 4, the possibility measures of thesituation that the tension of the measured tire bead steel wire belongs to the fuzzy sets representing the tire bead steel wire tightness state are calculated; 5, diagnosis of the steel wire tightnessstate is achieved during tire bead steel wire drawing. The method for diagnosing the steel wire tightness state in the tire bead steel wire drawing process can accurately diagnose the steel wire tightness state in the tire bead steel wire drawing process, so that the drawing precision of the tire bead steel wire is guaranteed, and a low wire fracture ratio is guaranteed.
Description
technical field [0001] The invention relates to the technical field of steel wire drawing in mechanical engineering, in particular to a method for diagnosing the tightness of the steel wire during bead steel wire drawing. Background technique [0002] With the development of bead wire drawing machinery and equipment, the bead wire drawing speed is getting higher and higher, the highest has reached more than 16 meters per second. The out-of-roundness is less than 20μm, and the broken wire rate is 1 million meters per time. When the bead wire drawing mechanical equipment is working, the tightness of the bead wire during the drawing process plays an important role in achieving high dimensional accuracy and shape accuracy, low wire breakage rate, and low lateral / longitudinal runout. Therefore, ensuring a good bead wire drawing working state has become a necessary condition for bead wire drawing, and it is also a key to ensure bead wire drawing dimensional accuracy, shape accura...
