Manufacture method of single side ridge type water retaining rubber plate of airplane tire

Abstract

The invention discloses a manufacture method of a single side ridge type water retaining rubber plate of an airplane tire. According to the manufacture method, one side with the water staining rubber plate is designed at a lower mold of a vulcanization mold in advance for vulcanization; an extruding opening model is designed according to the shape of the designed water retaining rubber plate and is used for extruding out a rubber strip of the water retaining rubber plate; and during the tire vulcanization, the rubber strip subjected to pretreatment is put in a groove of a lower mold to be integrally vulcanized and formed with a pretreated forming tire blank. The manufacture method mainly belongs to the method that before the vulcanization, a rubber strip semi-finished product is preset in the mold, and the forming and the fixation in the mold are realized through vulcanization. The method has the advantages that the problem that the water retaining rubber plate position generates the defects of rubber lack, tire cavity thread exposing and the like after the airplane tire vulcanization of the single side ridge type water retaining rubber plate can be effectively solved, and the product quality is improved; and the water retaining rubber plate is prevented from being thrown away in the tire use process, the number of use times can be increased by more than ten times, the service life of the tire is prolonged, and the safety performance of an airplane is improved.

Description

technical field [0001] The invention relates to aircraft tires, in particular to a method for manufacturing a single-side ridge-type water-retaining rubber sheet for aircraft tires. Background technique [0002] Aircraft tires with ridge-type water-retaining rubber plates refer to aircraft tires that have a full circle of raised rubber plates in the upper part of the sidewall of the tire along the circumferential direction and flared outwards in the shape of a trumpet, and are installed on the nose landing gear of the aircraft. The role of the ridge-shaped water-retaining rubber plate is to change the jet flow form of the water and mud discharged when the tires contact the runway, so that the water and mud are discharged sideways along the water-retaining plate to avoid entering the air intake of the rear-mounted jet engine of the aircraft . [0003] Aircraft tires with ridge-type water-retaining rubber plates can be designed as one-sided or double-sided ridge-type water-r...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the defects existing in the existing manufacturing method, and provide a kind of manufacturing method of the one-side ridge type water-retaining rubber plate of aircraft tire, this method can effectively solve the problem of the single-side ridge-type water-retaining rubber plate. After the tire is vulcanized, defects such as lack of rubber and exposed lines in the tire appear on the water-retaining rubber plate to improve product quality
