Abstract

The invention relates to a solid tire vulcanizing method and a vulcanizing set thereof, and belongs to the technical field of tire vulcanization. The solid tire vulcanizing method comprises: carrying out shaping and vulcanization separately, wherein a tire is put into a self-locking pressure maintaining die during shaping, and subjected to pressurizing and self-locking pressure maintaining to finish the shaping process; and carrying out the process of vulcanizing, wherein the die is placed into a vulcanizing furnace, a sealed space is formed in the vulcanizing furnace, and the die is heated to achieve vulcanization of the solid tire through steam flowing an upper heating plate and a lower heating plate. The vulcanizing set comprises a vulcanizing machine and a hoisting device, wherein thevulcanizing machine is provided with a shaping device and a vulcanizing device, the shaping device and the vulcanizing device have split structures, the vulcanizing device has a furnace type structure, and a main body frame is connected with a main driving hydraulic cylinder and a steam supply and discharge system; and the main driving hydraulic cylinder is connected with a furnace cover of the vulcanizing machine through a connecting pin shaft at the top of the hydraulic cylinder, the upper heating plate and the lower heating plate are arranged in a box body, the heating plates are connectedwith the steam supply and discharge system, and the box body is provided with a heat insulating layer. The method simplifies equipment structure, reduces energy consumption of products, and has the advantages of high production efficiency, high vulcanizing precision, and the like.

Description

technical field [0001] The invention belongs to the technical field of tire vulcanization, and in particular relates to a solid tire vulcanization method and a vulcanization unit thereof. Background technique [0002] The vulcanization process is an important process in the production process of rubber tires. The molecular structure of the rubber is changed through vulcanization, and its comprehensive performance is significantly improved. At present, most of the vulcanization processes in the tire manufacturing process adopt the traditional tire vulcanization process that has been used since the 1960s. The traditional vulcanizing machine has 2 vulcanizing stations, and the tires are shaped and vulcanized at the same time. Each vulcanizing machine needs to be independently equipped with 2 electric control cabinets and 2 hydraulic devices. In this process, the boiler is subjected to pressure of 160-250 tons and high-temperature steam of 180-220 degrees Celsius for a long ti...

Problems solved by technology

[0004] The mechanical tire vulcanizing machine generally adopts a four-bar linkage mechanism. It uses the four-bar linkage mechanism to perform mechanical movement to realize the tightness of the upper and lower molds. After pressurization and heating, the tire is vulcanized in the mold. Its disadvantages are as follows: The structure is complex, heavy, and includes a crank gear transmission mechanism; the second is poor rigidity, such as the beam and the four-link are easily deformed; the third is that the life of the mold is greatly affected by the deformation of the beam, and the fourth is the opening and closing of the mold. Long time and low efficiency; Fifth, the maintenance of equipment is large

Due to structural requirements, this kind of tire vulcanizing machine equipment is relatively large, heavy and complicated, and the manufacturing of the product is difficult and costly
