Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an improvement method to ensure the rational distribution of materials at the bottom of the tire bead, to ensure a reasonable distribution of materials at the bead part of the finished tire, to avoid quality problems such as the bead bead showing lines and large edges, and at the same time reduce the Too much glue at the bottom of the bead leads to quality problems such as spinning and bursting

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] The present invention is to existing tire bead outer profile diameter ( figure 2 ) and the matching of the tire embryo diameter are analyzed to determine the appropriate tire bead ring diameter.

[0031] Curve shape of the fan block: For each tire manufacturer, the research on the curve shape of the fan block is still in a blank state, and the size provided by each building drum manufacturer shall prevail. With the refinement of the product structure of each series of specifications, the current general-purpose fan-shaped block curve is difficult to meet the existing product requirements. For this, the compression ...

Abstract

The invention belongs to the field of tire component production, is applied to tire blank forming engineering, and particularly relates to an improvement method for ensuring reasonable material distribution of a tire bead bottom. The method comprises the following steps of calculating a thickness of the tire bead bottom and a thickness of a tire bead transverse material according to material distribution of a tire blank bead opening part; comparing the thickness of the tire bead bottom and the thickness of the tire bead transverse material with a finished tire material distribution thickness theoretical value; calculating a tire bead bottom compression ratio and a tire bead transverse compression ratio; determining whether the tire bead bottom compression ratio and the tire bead transverse compression ratio meet tire bead part design size requirements or not; if yes, determining that a fan-shaped block curve design is reasonable; and if not, redesigning a fan-shaped block curve. According to the method, reasonable distribution of the finished tire bead part material is ensured, the quality problems of large edge of a tire bead seam allowance and the like are avoided, and meanwhile, the quality problems of laddering explosion and the like caused by excessive glue stored at the tire bead bottom are also reduced.

Description

technical field [0001] The invention belongs to the field of tire component production and is applied to tire embryo forming engineering, in particular to an improved method for ensuring the rational distribution of materials at the bottom of the tire bead. Background technique [0002] Tires are an indispensable part of vehicles such as cars and trucks, and the performance of these vehicles is closely related to the characteristics of the tires. The bead part of the tire component takes the role of fixing the tire on the rim, and transmits the driving force, braking force and rotational power of the adjustment direction from the vehicle to the ground, which not only prevents the tire from falling out of the rim, but also reinforces the The sidewall is rigid, bears the force of the carcass deformation on the tire, and ensures the driving, braking and handling safety of the vehicle. It is an important part of the tire's safe use. [0003] Molding engineering is the process o...
