A kind of production method and production system of rubber parts

Abstract

The invention provides a production method and production system of rubber parts. The production method comprises the following steps: 1) cutting the molded rubber strip after constant temperature treatment to obtain a working rubber strip with a length of L; 2) cutting the working rubber strip The strip is molded and then subjected to low temperature treatment to obtain the rubber part; the temperature of the constant temperature treatment is below 50°C, and the time of the constant temperature treatment is not less than 4h; the temperature of the low temperature treatment is below 5°C, and the The time of low temperature treatment is not less than 4h. By controlling the processing temperature and cutting size of the rubber parts during the molding process, the method reduces the influence of the instability of the raw materials and the environment on the dimensional stability of the rubber parts, and realizes the improvement of the dimensional accuracy of the rubber parts with low investment, and reduces the size of the rubber parts. The size deviation between the actual size of the rubber part and the target rubber part.

Description

technical field [0001] The invention relates to a production method and a production system of rubber parts, belonging to the field of rubber product production. Background technique [0002] In the manufacturing process of rubber parts, the raw materials need to be mixed first, and then vulcanized to obtain rubber parts, so that the original linear molecular chains are converted into three-dimensional crosslinked networks, so that they have excellent physical and chemical properties. It is precisely because of its excellent physical and chemical properties that rubber products are more and more widely used in daily production and life. Generally, rubber parts are used in conjunction with other components. Taking rubber seals as an example, only when the rubber seals and the functional parts used with them are compatible can it be beneficial to exert the excellent physical and chemical properties of the rubber seals. . [0003] In the production process of most rubber part...

Problems solved by technology

However, due to the difference in raw material batches, it is easy to cause inconsistent changes in the physical properties of the rubber during the molding vulcanization process, which not only makes the size of the rubber parts produced in different batches different, but also makes the actual size of the rubber parts in each batch different from the target rubber. There are different degrees of difference in the size of the parts

In addition, environmental changes and seasonal changes in the production process will also have an impact on the precise control of the dimensional error of rubber parts

The dimensional deviation caused by the above-mentioned various reasons will often limit the competitiveness of related enterprises in the production of rubber products, especially precision rubber products, and affect the production efficiency and benefits of enterprises.

[0004] In the prior art, in order to accurately control the size of rubber parts, various factors such as production equipment, production environment and production personnel in the rubber production line are often controlled on a large scale, which undoubtedly leads to a substantial increase in production costs, and the control effect is also incomplete As one wishes
