Embodiment Construction

[0023] The present invention provides a method for confirming the validity of identifying bubble defects in giant tires with X-rays, comprising the following steps:

[0024] S1: During the trial production of the first tire of the new product, a 4mm*2.5mm*1.0mm (note: length*width*thickness) plastic pad 5 is symmetrically attached on both sides of each belt layer to act as artificial manufacturing bubbles, and the different layers of belt layers are staggered up and down between the plastic pads 5 on the same side; the specific operations are as follows:

[0025] A: as figure 1 As shown in the figure, after the lamination of the first belt layer is completed, symmetrically attach the plastic pads a1 and a2 on both sides of the end of the 1# belt layer 1, and then mark a on the laminating drum on the corresponding side; then Carry out the 2# belt layer 2 lamination, after the end, the plastic pads b1 and b2 are symmetrically attached to both sides of the end of the 2# belt lay...

Abstract

The invention discloses a method for confirming the effectiveness of using X-rays to identify inner air bubble defects in giant tires, and belongs to the technical field of engineering machinery tire manufacturing. The technical solution is: attach a plastic pad between each belt layer and the base rubber and the tread rubber to act as air bubble defects, and then use X detection equipment to identify air bubble defects and optimize its parameters, and finally obtain a product that can The detection parameters that identify all plastic pads are valid parameters. The present invention can improve the effectiveness of X-ray equipment detection parameter setting, and avoid tire air bubble defect identification and control not in place, which leads to shoulder-off quality fluctuations in the market.

Description

technical field [0001] The invention relates to the technical field of construction machinery tire manufacturing, in particular to a method for confirming the validity of identifying bubble defects in giant tires with X-rays. Background technique [0002] In the production process of giant engineering radial tires, due to the influence of production equipment, technological process and other factors, there are often quality problems such as air bubbles in the tire, thin wire opening, and wire crossing, which directly or indirectly affect the product quality and shorten the service life of the tire. Therefore, X-ray inspection must be carried out on each finished radial tire in order to detect problems in time and take measures to control them. [0003] At present, the same industry has insufficient effectiveness in the identification of air bubbles in the belt layer and the wound tread during the X-ray inspection of giant radial tires, which leads to the early shoulder delam...
