Problems solved by technology

During the design and debugging process, we found that the mathematical model of the currently used green tire contour is very different from the actual green tire contour, which leads to inaccurate simulation of some rubber strip arrangements, and the operation is more troublesome in the process of editing the formula

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0022] The present invention mainly uses the laser ranging sensor to measure the tire blank radius data, and then performs data processing on the measured data to generate the actual tire blank profile, and finally the winding simulation software uses the calculated tire blank profile to perform strip arrangement simulation to obtain more accurate simulation data. The specific plan has the following aspects:

[0023] 1. Write a PLC program based on Logix5000 software to collect 500 point radius values ​​of the green tire section where the laser distance measuring sensor measures, and collect 4 tire blank section data in total.

[0024] 2. Use FactoryTalk View SE software and VBA to process the tire blank profile data to obtain the actual tire blank profile.

[0025] figure 1 It shows a schematic view of the relative position of the laser...

Abstract

The invention discloses a method for scanning and reconstructing the section of a blank. The method comprises the steps of 1) determining the mounting position of a laser ranging sensor; 2) confirming a scanning track and start-stop positions; 3) determining a sampling period delta T, and collecting 500 points during the scanning process; 4) collecting and processing data; 5) carrying out the curve fitting to obtain a blank contour mathematical model. According to the technical scheme of the invention, a mathematical model conforming to the contour of an actual blank is established, so that the rubber strip arrangement and simulation can be more accurate. Parts that can better meet the process requirements can be produced. Meanwhile, the input number of a formula is reduced, so that the formula can be conveniently edited. Moreover, the speed of an assembly drum can be more accurately controlled, and the winding production efficiency is improved.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a method for scanning and reconstructing a section of a green tire. Background technique [0002] The tread winding production line is mainly used for the winding molding of tire sidewalls and treads such as engineering tires, bias tires, and all-steel radial tires, replacing the sleeve molding in the original process. It winds the rubber strips on the surface of the tire blank according to a certain arrangement rule to form a tread, sidewall and other components that meet the technological requirements. The tire blank contour mathematical model of the existing tread winding production line software is a model composed of two arcs and a straight line. During the design and debugging process, we found that the currently used mathematical model of the green tire contour is very different from the actual green tire contour, resulting in inaccurate simulation of some rubber strip a...
