Problems solved by technology

However, in actual operation, to wind the designed tread shape, many times the problem cannot be solved by winding only one layer in the molding process.
However, there is no existing technology to study this

Embodiment 1

[0022] Such as figure 1 As shown, it is a schematic diagram of the outer profile of the tire tread section to be layered in this embodiment. It can be seen from the figure and the prior art that the tire tread profile is mainly composed of lines, which is a symmetrical structure in the middle, L is the left side, and R is the right side, and the slope of the line may be positive or negative.

[0023] A kind of tire tread layered winding method of the present embodiment is similar to figure 1 The image shown is layered as follows:

[0024] A. Delamination of the tread in the winding machine forming process;

[0025] B. Wrap the tire blank with rubber strips according to the above-mentioned layering method.

[0026] The steps of the layered approach described in Step A are as follows:

[0027] (1) Establish a coordinate system with the vertical line of the tire tread as the Y axis and the bottom layer of the tread as the X axis; figure 2 shown.

[0028] (2) Select the inf...

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 [0001] The invention relates to the field of tire processing research, in particular to a tire tread layered winding method. Background technique [0002] The tire tread winding molding is divided into two stages, one is the molding process stage, this stage is to wind the unvulcanized rubber strip on the tire blank through winding technology, at this time there is no sudden pattern shape on the tread, but similar Trapezoidal gradient shape; the other is the vulcanization process stage. In this stage, the semi-finished product processed by the molding process is put into the mold for vulcanization. Since the tread rubber is still fluid at this time, the tire is produced through the extrusion of the mold. pattern. [0003] Tread winding has a long history as a tire building technology. The Chinese invention patent with application number 200910041591.6 discloses a tire tread winding control method. The head walking trajectory and speed are adjusted in real t...
