A kind of preparation method of all-steel standard embryo

Abstract

The invention relates to a preparation method of a full-steel gauge tire blank. The preparation method comprises the following steps that 1), a lining layer and a tire body are compounded, and then the lining layer lamination and the tire body sewing are carried out; 2) a bead ring part is fastened on a ring disc, a tire body cylinder is grabbed, the bead ring is attached to a forming drum and isused for pressing a triangular tire body, and the triangular tire body is reversely wrapped and compacted by an anti-encapsulation capsule; 3), the left tire side and the right tire side are positioned and attached to the tire body in a positioning manner so as to complete a section of tire blank; 4), the belt layer and the tire tread are attached on the belt ply laminating drum, a crown compositepart is formed; and 5) a section of tire blank seam allowance is placed on a PU ring, the PU ring is supported, clamping a section of tire blank sub-opening, conveying the crown composite part to a preset position, a section of the tire blank is slowly inflated, and when a section of the tire blank is in contact with the crown pre-composite member, the air inflation is stopped, and the combined compression roller is used for carrying out tire tread, the tire side is rolled, the PU ring is contracted after the rolling is completed, the tire blank is taken out, and the tire blank is manufactured. The product produced by the secondary method is good in quality.

Description

technical field [0001] The invention relates to the technical field of tire processing, in particular to a method for preparing an all-steel tire blank. Background technique [0002] The radial tire building process is to combine all the prepared semi-finished parts, such as carcass, belt layer, bead ring, inner liner and various rubber parts, on the building machine to form a green tire. This process is an extremely important process in the entire radial tire manufacturing process. Because various semi-finished parts are repeatedly unwound, coiled, etc. during storage, movement, and molding manufacturing operations, they are easily deformed by factors such as external force stretching, and the layers of semi-finished parts such as carcass and belt layers will be due to sticking. Bubbles will be generated if the joint is not tight, and the deviation of the position of the parts will cause the uneven cross section of the finished product, etc., which will inevitably have a g...

Problems solved by technology

Because various semi-finished parts are repeatedly unwound, coiled, etc. during storage, movement, and molding manufacturing operations, they are easily deformed by factors such as external force stretching, and the layers of semi-finished parts such as carcass and belt layers will be due to sticking. Air bubbles will be generated if the joint is not tight, and the deviation of the position of the parts will cause the unevenness of the finished product section, etc., which will inevitably have a great impact on the product quality

At present, most of the all-steel tires adopt one-time molding, but the equipment for one-time molding is complicated, and the accuracy and quality of the molding are not high, which affects the overall quality of the tire.
