Bead forming device and forming method for rubber tire manufacturing

Abstract

The invention relates to a bead forming device and a forming method for rubber tire manufacturing, comprising a support plate, a forming roller and a gluing mechanism, a forming roller is installed on the side wall of the support plate, a gluing mechanism is installed inside the forming roller, and The roller includes feeding cylinder, fixed cylinder, connecting plate, telescopic rod, connecting screw and connecting block. The gluing mechanism includes placing frame, linkage plate, lifting plate, lifting spring, gluing branch chain, connecting rod, rotating plate, rotating motor and The pump conveyor, the placement frame includes a rotating ring, lifting frame, placement plate and connecting structure, and the gluing side chain includes a rubber roller brush, a driven gear, a driving gear and a gluing groove. The present invention adopts a multi-station mode to apply glue to the steel traveler synchronously. During the glue coating process, through the rotation of the gluing mechanism and the relative movement between the gluing mechanism and the steel traveler, the cooperation can achieve the expansion of gluing The purpose of the range is to significantly improve the uniformity and comprehensiveness of glue application.

Description

technical field [0001] The invention relates to the technical field of rubber tire processing, in particular to a bead forming device and a forming method for the production and manufacture of rubber tires. Background technique [0002] The bead, also known as the bead, refers to the part of the rubber tire installed on the rim, which is composed of bead core and chafer cloth. It can withstand the tensile force caused by internal pressure, and at the same time, it can overcome the lateral force of the rubber tire during cornering, so that the outer tire will not come out of the rim. Therefore, the tire bead must have high strength, and the structure should be tight and firm, and it is not easy to deform. [0003] During the rubber tire bead forming process, it is necessary to apply a layer of glue on the surface of the bead to prepare for the bonding of the bead and the apex. The following problems exist in the process of applying the bead: [0004] (1) The traditional met...

AI Technical Summary

Problems solved by technology

[0004] (1) The traditional method mostly uses manual gluing on the traveler, workers can only process one traveler at a time, the processing efficiency is low, and due to the inherent instability of manual operation, the uniformity of gluing work cannot be guaranteed And comprehensiveness, after the traveler is bonded with the triangular rubber strip, it is easy to have warping and falling off defects;

[0005] (2) In order to ensure the comprehensiveness of glue application, the amount of glue applied to the traveler is often relatively large. If the amount of glue applied is not properly controlled, it will cause the glue to drip from the traveler. Not only will it pollute the working environment, but it will also make the traveler glued surface appear uneven, and the glue coating effect will be adversely affected
