Twice method run flat tire one section forming and fitting drum

Abstract

The invention relates to a one-stage forming and laminating drum for run-flat tires with two methods. It is provided with left and right guide discs on both sides of the main shaft sleeve, guide grooves are respectively provided on the left and right guide discs, and a support plate is installed on each pair of guide grooves, and a support plate is installed on the outside of each support plate. , corresponding to the assembly of a drum tile; on the main shaft sleeve, there is also a cylinder device, on the outer wall of the cylinder, there is a nylon cone, the nylon cone is fixedly connected with the cylinder, and on the inside of the support plate, there is a The nylon cone taper fits the slope. In the present invention, step-by-step lamination is adopted, the first step is to paste the inner liner in the contracted state, the second step is to apply the reinforcing glue in the expanded state, and then paste the carcass, press, wrap, buckle, reverse wrap, Press again. The drum is expanded through the transmission mechanism, so that the inner lining layer is evenly attached to the drum tile through radial stretching, which solves the problem of discounting the inner lining layer and residual air bubbles in the past, thereby improving product quality.

Description

technical field [0001] The present invention is a one-piece forming and laminating drum for run-flat tires (also called one-stage forming and laminating drum for zero-inflation tires) produced by two methods. It is suitable for the molding of run-flat tires produced on a secondary-stage one-stage molding machine on a special equipment for semi-steel passenger radial car tires. Background technique [0002] With the rapid development of the automobile industry, the increasing number of high-end cars, and the improvement of people's safety awareness, the demand for high-performance run-flat tires is also increasing, and the technical requirements for the tire manufacturing industry are also getting higher and higher. At present, the one-stage forming drum of the secondary method generally adopts the same forming drum as the ordinary tire, which will have the following disadvantages: 1. The reinforcing rubber strip cannot be positioned; 2. After the carcass is not flat, it is d...

Problems solved by technology

[0004] The purpose of the present invention is to overcome and solve the problems of the above-mentioned background technology, and provide a kind of reserved reinforcing glue groove, the inner lining layer is radially stretched and laminated, so that the inner lining layer is completely discounted, residual air bubbles are left, the reinforcing glue is not positioned, and the carcass Inadequate pressing and other defects, the product qualification rate has reached 100% two-way run-flat tire one-stage forming and laminating drum
