Embodiment Construction

[0020] The content of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited.

[0021] A tire tread profiling winding method based on the pixel method, comprising three steps: tread profiling winding based on the pixel method, shape control of the winding rubber strip, and open-loop profiling process control.

[0022] The specific steps of the tire tread profiling winding based on the pixel method are as follows:

[0023] (1) Establishment of space mapping of multi-dimensional coordinates of tire tread

[0024] The shape of the tire tread is described in an object-oriented manner, and its structure is described by an array P: the array P consists of abscissa point L, ordinate point H, and abscissa point correction L m , ordinate point correction H m , the number of layers is composed of Layer, and the shape of the tread is obtained by inputting a group from P 1 (L 1 , H 1 , L m1 , H m...

Abstract

The invention discloses a pixel-method-based tire tread profiling twining method. The method comprises three steps of pixel-method-based tire tread profiling twining, shape control over twining adhesive tape and controlling of a ring opening and profiling process. The pixel-method-based tire tread profiling twining comprises the steps that interspace mapping of a multi-dimensional coordinate of tire tread is established, and a pixel-method-based profiling mathematical model and an algorithm are established. The pixel-method-based tire tread profiling twining method has the beneficial effects that by establishing the novel model which is oriented to a tread shape of an object, the aim of the tread shape description allowed by any tread twining technologies can be achieved, and the accuracy requirement of the mathematical model of the tread twining technologies of a truck tire, an agricultural tire, an engineering tire, a diagonal tire of a special tire and a radial tire is totally met. The thickness error of the profiled tire tread is less than 1.5 mm, the error of the two ends of the tire side is less than 3 mm, and the weight error of the tire tread is within 0.5%.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a tire tread profiling winding method based on a pixel method. technical background [0002] Most of the traditional winding machines are realized by the closed-loop winding principle based on thickness measurement, but due to the characteristics of rubber and the instability of the winding blank, there are uncertain systematic errors in the thickness detection, so the weight of the tread winding compound and the tire The shape is not guaranteed, which affects the yield and quality of the tire. Contents of the invention [0003] In order to solve the above-mentioned shortcomings, the present invention discloses a tire tread profiling winding method based on the pixel method, which solves the problem that the weight of the winding rubber material and the quality of the tire shape are difficult to control and the tire yield is low when making the tire tread. The effect of the p...
