Mechanical assembly drum with attaching and compacting functions

Abstract

The invention relates to a mechanical forming drum with compaction function, which is characterized in that on a main shaft sleeve adjacent to a fan-shaped block cylinder, the flap cylinders are also installed. A set of flap cylinders is installed on the outer circumference, which is disposed on the inner side of the fan-shaped block. On the outer circumference of the flap cylinder, a width adjusting side ring is also installed. A groove ring is jacketed on the outer circle of a turn up cylinder, which is linked with the front-end flange of the turn up cylinder. Between two side drums, a middle width-adjusting ring is fixed, which is overlapped with the width adjusting side ring and can be dislocated mutually. The groove ring surface is contained in the turn up roller arm surface in the groove ring, the width-adjusting side ring surface, the middle width adjusting ring surface and the sealed plastic ring surface. When the turn up roller arm is disposed on the original position, a basically complete cylinder surface is formed for the compaction of the carcass parts to support the tire body. With the invention, the tire compaction and forming processes are integrated, meanwhile the functions of compaction and the mechanical forming drums are also provided. Therefore, the invention provides conditions for the one stage forming of steel-belted tire. With high efficiency, the quality of the produced tires is excellent.

Description

technical field [0001] The invention relates to a machine for manufacturing rubber tires, in particular to a mechanical forming drum with laminating and compacting functions on a one-shot forming machine used in the production of semi-steel radial tires. Background technique [0002] In the existing production of semi-steel radial tires, the special equipment for tire building usually includes a first-stage forming machine and a second-stage forming machine. The molding process requires that the inner liner film and cord are transported to the laminating drum by the feeding device, and after the finger-shaped positive wrap, the buckle ring and the capsule reverse wrap, the sidewall and the required rubber parts are packed according to the sequence specified by the process. Fit one by one in place, and complete the forming process of a section of the radial tire carcass after sufficient pressing. Then transfer the completed one-stage forming carcass to the second-stage formi...

AI Technical Summary

Problems solved by technology

[0004] In the secondary molding process of the above-mentioned tire blank, after the carcass is completed on the bonding drum of the first-stage forming machine, the carcass is unloaded and installed on the forming drum of the second-stage forming machine. The crown body completed above is combined and shaped to form a whole tire embryo. The lamination of the tire body and the molding of the tire embryo are respectively completed by two forming drums with different functions on two different molding machines. The work efficiency is low and the quality of the produced tires Poor, takes up a lot of space, with the development of special equipment for tires, it can no longer meet the needs of the market

[0005] The automatic turn-up rolling mechanical forming drum usually used in the production of truck tires has the function of turning-up rolling forming. Please refer to the invention patent: an automatic turn-up rolling mechanical forming drum, patent number ZL03102556.0, but the forming drum Does not have carcass fitting function
