Automobile tire pattern forming method

Abstract

The invention discloses an automobile tire pattern forming method, which comprises: mold forming processing-mold joint surface roughness finishing-mold assembly, wherein the method of combining uniform heating interference fit and bolt connection is adopted when assembling the mold Dedicated. On the one hand, the production process adopted by the present invention can effectively improve the equipment accuracy of the tire pattern ring mold and the connection quality of the joint surfaces after assembly, thereby helping to improve the production quality of the tire; The phenomenon of mold damage occurs, thus effectively prolonging the service life and reuse rate of the mold.

Description

Technical field [0001] The invention relates to a method for forming automobile tire patterns, belonging to the field of tire mold processing technology. Background technique [0002] In tire production, especially tire surface pattern forming and processing, various types of pattern ring molds are needed for production. The pattern ring molds used in the project are generally composed of shell, pattern ring and side plate. Part of the assembly structure. In the current assembly process, due to the lack of fine requirements for the important connecting parts of the shell, the pattern ring and the side plate and the corresponding professional assembly process, it has led to the current implementation of the pattern ring mold When assembling, there are various types of assembly methods, and there are often large cumulative tolerances during assembly due to excessive machining errors of the shell, pattern ring and important connecting parts of the side plate, which leads to the shel...

Problems solved by technology

[0002] In the production of tires, especially in the production of tire surface pattern forming and processing, it is necessary to use various types of tread ring molds for production, and the tread ring molds used in the purpose are generally composed of shells, tread rings and side plates. Partial assembly, in the current assembly process, due to the lack of fine requirements for the important connecting parts of the shell, pattern ring and side plate and the corresponding professional assembly process, it has led to the current process of pattern ring mold During assembly, various assembly methods are used, and there are often large cumulative tolerances during assembly due to excessive processing errors of the important connecting parts of the shell, pattern ring and side plate, resulting in the shell, pattern ring and side plate. When the side plate is connected, there is a large position deviation, which leads to the disadvantages of failure to connect or excessive gap between the contact surfaces after connection. In order to overcome these disadvantages, the current common practice is to use external force to adjust the position of each connecting part, or Adding gaskets in the gap of the connecting surface, on the one hand, caused the extremely poor accuracy of the pattern ring mold, on the other hand, it also caused great damage to the structure of the pattern ring mold, greatly reducing the service life of the pattern ring mold
