Abstract
The invention discloses a tread layering method in a tire winding machine forming process. The method comprises the steps of selecting turning points on a tire tread and calculating the coordinates of each turning point in a coordinate system; obtaining equal diversion points of each turning point between a left side edge and a right side edge on a vertical coordinate line, connecting the equal diversion points on each layer as layering points, making horizontal lines parallel to the X axis along the equal diversion points on the vertical coordinate lines of the highest points of the left side edge and the right side edge, and using the intersection points of the horizontal lines and the left side edge and the right side edge as layer points; sequentially writing the layering points into an array according to the outline position and connecting the points on each layer in the array to realize layering of the tread. The method can realize uniform thickness of each layer after layering, so that the screw pitches of the wound model are uniform, and the uniform screw pitch distribution facilitates greatly reducing air bubbles during winding.
Description
Technical field
The present invention relates to tyre production research field, particularly a kind of tread separation method in tyre wrapping machine moulding process.
Background technology
Tire tread is Wrapping formed is divided into two stages, and one is the moulding process stage, and this stage is that unvulcanized adhesive tape is wound on green tyre by winding technology, now on tyre surface, there is no the decorative pattern shape of sudden change, but similar trapezoidal grading profile; Another is the sulfuration process stage, this stage is the semi-finished product after moulding process processing to be put into mould vulcanize, due to this time tread rubber still there is mobility, therefore the extruding by mould produces tyre tread.
Tread wrapping has a long history as the technology of tire building, application number is that 200910041591.6 Chinese invention patent discloses a kind of controlling method for wrapping surface of tire, the method is to the emulation of tread wrapping process simulation, wrapping machine head run trace and speed are adjusted in real time simultaneously, thereby improved the tread wrapping quality of tire.But in practical operation, be wound around out the tire tread form of design, many times can not only in the moulding process stage, be wound around one deck and just deal with problems.
Because adhesive tape thickness, width and overlap are very large on winding mass and shape impact, when adhesive tape is too thick, volumetric errors is larger, and exhaust effect is bad; Adhesive tape width is larger, be wound around efficiency higher, but more wayward quality and shape, so the thickness of adhesive tape is generally 5 millimeter, width at most can be over 100 millimeters, and carry out in tire winding process actual, many times needing the thickness of winding tyre surface is out 100 or even 200 millimeters of ranks, and therefore also just very necessary to the layering winding of tyre surface, layering is got, of great advantage to winding effect, and can greatly improve the fidelity of emulation and real effect.But still do not have at present prior art to study this.
Summary of the invention
Main purpose of the present invention is that the shortcoming that overcomes prior art is with not enough, a kind of tread separation method in tyre wrapping machine moulding process is provided, adopt the method to carry out layering, can make after layering the Thickness Ratio of every layer more even, and then the pitch ratio that makes to be finally wound around model is more even, thereby can reduce the bubble producing in actual winding process, improve the quality being wound around.
Object of the present invention realizes by following technical scheme: a kind of tread separation method in tyre wrapping machine moulding process, and step is as follows:
(1) set up one and take tire tread perpendicular bisector as Y-axis, the coordinate system that tread base is X-axis;
(2) select the flex point on tire tread, flex point comprises two ends end points, and abscissa is that positive end points is the first end points, and abscissa is that negative end points is the second end points; According to flex point position on tyre surface outer contour, write successively an array, and calculate the coordinate of each flex point in coordinate system;
(3) search obtains the point that ordinate is the highest, and from these points, chooses the point of abscissa maximum and abscissa minimum, is defined as respectively the first separation and the second separation;
(4) for the first separation, the second separation and the flex point between the two, each flex point ordinate is divided into N equal portions according to divided number of plies N, record N-1 coordinate points on its vertical coordinate line, along Y direction, be labeled as successively Q
i,j, the label that i is this flex point, j represents j coordinate points on the corresponding vertical coordinate line of this flex point institute, j 1～(N-1) between; Connect successively between the first separation and the second separation j coordinate points on the corresponding vertical coordinate lines of all flex points, obtain the mid portion stratification line of tire tread j layer;
For the limit, left side between the right edge between the first separation and the first end points and the second separation and the second end points, along N-1 coordinate points on the first separation vertical coordinate line, do the horizontal line that is parallel to X-axis, record the intersection point of these horizontal lines and limit, left side, right edge, the end points using these intersecting point coordinates as stratification line is inserted in array according to position on tyre surface outer contour; Connect the point on every one deck in array and complete tread separation.
Preferably, for the flex point between the first separation, the second separation, between each flex point, increase several data points, according to divided number of plies N, the ordinate of data point is divided into N equal portions, j coordinate points on its vertical coordinate line, is designated as the point on the stratification line of tire tread j layer equally.Thereby by determining the multiple spot left side, add the precision in man-hour.
Compared with prior art, tool has the following advantages and beneficial effect in the present invention:
1, the inventive method is divided equally tire tread on thickness direction, thereby make after layering the thickness of every layer all more even, thereby the pitch that is finally wound around model also can be more even, this uniform pitch is distributed with to be beneficial to and greatly reduces the bubble producing in winding process.
2, in the present invention, for tire tread, be the situation of hypotenuse, algorithm is further improved, proposition does along the coordinate points of the N-1 on peak vertical coordinate line on hypotenuse the horizontal line that is parallel to X-axis, using horizontal line and limit, left side, the intersection point of right edge is as the end points of stratification line, thereby make the effect that both sides bound edge obtains after reality is wound around can be more identical with design.
