A tire processing method

Abstract

The invention discloses a tire processing and molding method, which comprises the steps of blank preforming, mold molding, vulcanization molding, etc., which are sequentially carried out, and a number of preformed grooves and preformed protrusions are preprocessed from the rubber blank which has not been molded, so as to Correspondingly adapted to each structure in the mold cavity, in order to process the corresponding tread grooves and tread ribs, especially through the above-mentioned blank preforming process, the rubber can be guided and evenly distributed, thus effectively Avoid the rubber material flow that may be caused by subsequent mold processing and related molding processes and the formation of rubber material accumulation on the edge of the tread rib, and further avoid the local rubber material protrusion of the tread rib caused by this phenomenon , so as to effectively optimize the distribution structure of the rubber material at the tire tread rib after processing and forming, thereby significantly improving the performance and service life of the tire, and optimizing the performance of the whole vehicle accordingly.

Description

technical field [0001] The invention relates to the technical field of tire design, processing and manufacturing, in particular to a tire processing and molding method. Background technique [0002] Tires are the only contact parts between the vehicle and the ground during daily driving. Therefore, the performance of the tires directly affects the driving performance of the vehicle. Among them, whether the stress distribution of the tire under the ground contact state is uniform is one of the extremely important performance indicators, especially for the acronym for NSB (Non-Skid Base, that is, the thickness of the rubber under the groove, which refers to the thickness of the tire under the main groove of the tread pattern. For thinner tires, it should be ensured that the rubber material layout design of each tire rib in contact with the ground is uniform and reasonable, so as to ensure the corresponding tire performance.

AI Technical Summary

Problems solved by technology

[0003] At present, in the molding process implemented in the tire processing process, the blank with relatively flat tread rubber material is usually used for molding processing, but this method causes the rubber material of the tread to flow to the tread ribs after the subsequent vulcanization treatment. Specifically, a large amount of rubber will form deposits inside the junction of the two adjacent surfaces of the tread rib, resulting in uneven distribution of the thickness of the overall internal rubber of the tread rib, resulting in ground contact shape and pressure during subsequent tire rolling work. Uneven distribution will seriously affect the running performance of the tire; and the above-mentioned local silted rubber material will produce a bulge at the junction of the two adjacent surfaces of the tread rib, resulting in the occupation of the distribution space of the wear-resistant rubber layer on the outer wall of the tire. As a result, the wear-resistant rubber layer on the outer wall of the tire is relatively thin, which is prone to premature wear during subsequent use and causes the rubber inside the tire to be exposed, which seriously restricts the service life and performance of the tire, and is detrimental to the safety of the vehicle. influences
