Embodiment 1

[0071] Example 1, such as Figure 1 to Figure 8 As shown, the vulcanization device used for retreading tires or manufacturing new tires for pre-vulcanization double-compound annular tread mainly includes an oil cylinder 10, a conical block 20, a movable core module 30, a support plate 40, a pattern mold 50 and a base 60. in,

[0072] The oil cylinder 10 is used to provide driving force to realize the pressure acting on the surface of the double-compound annular tread in the vulcanization process.

[0073] The conical block 20 driven by the oil cylinder 10 realizes vertical movement, and the conical block 20 drives the integral movable mandrel to retract inwardly or expand outwardly along the horizontal radial direction.

[0074] On the outer surface of the tapered block 20 , there are 10 sliding slots 23 symmetrically arranged with the same number as the movable core modules 30 . The T-shaped wear plate 41 at the end of the support plate 40 is nested in the slide groove 23 ....

Abstract

A method for producing pre-cured circular tread and the device thereof are provided. Said method comprises the following processes of: mixing rubber material, in which raw materials of rubber tyres are subject to mixing to obtain the mixed rubber; calendering, in which rubber sheets are calendered to obtain semi-finished tread products; cutting, in which the semi-finished tread products are cut at a certain length according to the size of tyres; vulcanizing, in which the cutted semi-finished tread product has its two ends connected before being pressed and vulcanized in the vulcanizing machine. A seamless, circular tread is produced after the vulcanization process. Moreover, a device used in the method is also disclosed.

Description

technical field [0001] The invention provides a method for producing a pre-vulcanized annular tread and a vulcanization device thereof, which are specifically applied to the production process of tire retreading and belong to the field of rubber machinery. Background technique [0002] Due to the popular use of vehicles such as automobiles and airplanes, a large number of scrap tires need to be disposed of every year. Not only formed a waste of rubber resources, but also brought a series of problems of environmental pollution. At present, for old tires whose tread patterns are worn out, the method of retreading is generally adopted to put them into recycling again. [0003] The existing tire retreading technology mainly uses a grinding machine to grind the tread of the old tire, then coats the middle rubber on the surface of the carcass, and then puts the new tread head and tail joints on the carcass. Pressing and attaching to form a composite part, and finally sent to the...
