Tire mold is used for curing all kinds of tires mold, the quality of its processing is also related to the quality and performance of the tire. With the equipment manufacturing and mechanical processing technology with each passing day, the tire mold processing technology is also undergoing tremendous changes, Mould on Tires which tire mold on the deep hole processing has been the tire mold processing difficult problem, with the traditional deep hole Compared with the processing, with a smaller diameter of the cutting tool, the length of the arbor, Mould on Tires chip and cooling cooling difficulties, frequent tooling vibration, the tool is difficult to observe the situation and other characteristics.
Tire mold deep hole processing process carried out a comprehensive study, the choice of the appropriate long-speed high-speed steel twist drill, select the appropriate cutting fluid, alloy steel mold parts for deep hole drilling test, for deep hole processing control process The Bartworth type IIR digital filter is applied to the process of machining control, taking into account the cutting vibration of the tool during the machining process, Mould on Tires taking the tool force to control the cutting state of the tool and taking the corresponding control method. This paper mainly introduces the characteristics of the deep hole machining of the tire mold and the status quo of the deep hole processing industry. The paper analyzes the deep hole of the deep hole machining system of the tire mold, In order to solve the problem that the tool cutting state is difficult to judge, Mould on Tires a reasonable digital filter is designed and applied to the process control process. The tooling control is used to control the feed and the tool cutting state is detected in real time. Intelligent control scheme. Based on the deep research on the drilling technology, the tool structure and parameters, the tool force analysis, the mechanical model of the deep hole drilling of the tire mold is established, and the digital control system of the tire die deep hole machining is designed. Through the experiment carried out a comprehensive verification, fully meet the system's processing accuracy and process requirements. In this paper, Mould on Tires the processing control of the deep hole of the tire mold is realized, and the performance of the machine is improved. The tool can be protected to the maximum extent possible, and the interference control factors such as drill bit wear and processing material are affected. The reliability of the process, reduce the possible cost loss, and maximize the production efficiency and economic efficiency.
Tire mold as a tire production line on the terminal forming equipment, Mould on Tires to a large extent determine the quality and appearance of the tire, the tire traction, braking force, wear resistance also have an important impact. In the tire preparation industry, the mold pollution and demoulding difficulties is a classic technical problems. Mold contamination can also cause a lot of problems, such as vulcanized rubber failure; vulcanized rubber stripping difficult; need for regular cleaning of the mold, etc., seriously affect the quality of tire production and production efficiency. It is therefore important to find an effective way to solve these problems. In order to find an effective way to solve the problems of tire mold pollution and mold removal, this paper mainly studies the following aspects. (1) Establish a surface characterization model for evaluating the performance of tire molds. In order to prepare high-quality tires, tire molds are required to have good vulcanization quality, easy mold release, anti-sticking, abrasion resistance, long life, easy cleaning and so on. The surface roughness (surface topography), element composition, coating thickness (section topography), friction coefficient, hardness, hydrophobicity and so on were found by analyzing the working performance of tire mold. And according to these parameters to establish the characterization model, Mould on Tires the tire mold qualitative and quantitative characterization. (2) design, preparation of different surface treatment process of surface integrity parameters of the test specimen. According to the characterization parameters and characterization methods needed in the characterization model, there are three main categories of measurement specimens: friction and wear measurement specimen (90), SEM specimen (30) and other measurement specimen (30). The samples were subjected to surface treatment such as sand blasting, nitriding, polishing, Teflon coating, CrN coating, DLC coating and the like. Which provides sufficient specimen for the surface integrity parameter measurement of different surface treatment process specimen. (3) to study the different surface treatment process on the tire mold composition and structure. Different surface treatment processes have different effects on the surface roughness, surface morphology, cross-sectional structure, surface element composition, etc., Mould on Tires and different compositions and structures cause different tire mold surface properties, and therefore require different surface treatment process components and The structure is measured to provide a basis for improved surface performance. (4) The surface properties (hydrophobicity, hardness and elastic modulus, bond strength, friction coefficient, etc.) of different surface treatment process specimens were measured and compared. The surface performance of different surface treatment process specimens, such as sandblasting, nitriding, polishing, Teflon coating, CrN coating and DLC coating, were used to find out the advantages and disadvantages of different surface treatment processes and the DLC coating. Mould on Tires Applicability is evaluated. To find an optimal surface treatment process to solve the problem of mold contamination and demoulding.
