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
The present invention relates to aero tyre, specifically a kind of manufacture method of one-sided ridge dash offset plate of aero tyre.
Background technology
Refer at the upper sidewall of tire along the circumferential direction have whole circle aero tyre projection and the flared offset plate of flare with the aero tyre of ridge dash offset plate, be installed on aircraft nose-gear and use.The effect of ridge dash offset plate is to change tire to contact the water of time discharge and the spray pattern of mud with runway, and water and mud are discharged to side along water fender, avoids entering the air inlet of the rear-mounted jet engine of aircraft.
Can be designed to one-sided or bilateral band ridge dash offset plate with the aero tyre of ridge dash offset plate, the one-sided aero tyre with ridge dash offset plate is for the nose-gear of dual tire wheel tire, and the aero tyre of bilateral band ridge dash offset plate is for installing the nose-gear of single tire.Aero tyre with ridge dash offset plate has become the standard facility of many business jet aircrafts now.
The relatively common aero tyre of manufacture method of the aero tyre with ridge dash offset plate wants complicated, has increased the manufacture of dash offset plate.When designing tyre sulfurizing mould, on mould, to increase by 1 (one-sided) or 2 (bilateral) grooves, for sulfidization molding dash offset plate.
The process for making of aero tyre mainly comprises: various semi-finished product (comprise cord, tyre surface, adhesive tape, steel ring etc.) preparation---fetus moulding (by various half-finished fitting together, paste tyre surface and be generally the final step of moulding)---fetus sizing---fetus packs mould into and vulcanizes---finished tire.
See figures.1.and.2, conventionally the dash offset plate manufacture method of aero tyre has two kinds, when these two kinds of methods all can be because of fetus moulding, tyre surface pastes askew, or the factor such as dash offset plate location is inaccurate and be out of shape when the sizing of fetus, cause fetus in the time of the sulfuration of dress mould, the groove location of the dash offset plate on fetus on position and the mould of dash offset plate adhesive tape produces deviation, thereby causes the position of sulfuration fetus dash offset plate out to occur starved, the defects such as exposed cord in tyre cavity.
These two kinds of manufacture methods also may cause dash offset plate sizing material skewness along the circumferential direction in addition, cause tire section distribution of material inhomogeneous, make the static unbalance of tire not reach standard-required and can cause dash offset plate in use to throw off and get rid of when serious, affect flight safety.
Summary of the invention
The object of the invention is the defect existing for solving existing manufacture method, and provide a kind of manufacture method of one-sided ridge dash offset plate of aero tyre, the method can effectively solve the problem that occurs the defect such as starved, exposed cord in tyre cavity after the one-sided aero tyre with ridge dash offset plate vulcanizes at dash offset plate position, improves the quality of products.
realize the technical scheme of the object of the invention:
A manufacture method for the one-sided ridge dash offset plate of aero tyre, comprises the steps:
(1) tyre vulcanized mould is divided into upper and lower mould, first tire is vulcanized at counterdie with a side design of dash offset plate; Design the extrusion shape of the mouth as one speaks of dash offset plate according to designed dash offset plate shape, for carry out the extrusion of dash offset plate adhesive tape on extruder;
(2) by the sidewall of stereotyped fetus one side to tire shoulder position, and the binding face of dash offset plate adhesive tape and fetus, brushes gasoline the surface preparation with wire brush hacking, to remove surface impurity, interleaving agent etc., to ensure end product quality;
(3) by after the cutting of dash offset plate adhesive tape fixed length, be connected into a ring-type, and the processing of brush gasoline hacking is done in butt joint;
(4) the dash offset plate adhesive tape that is connected into ring-type is placed on to the groove of dash offset plate sulfidization molding of sulfuration counterdie, entirety is set level whole;
(5) fetus is beforehand with to one of the brush gasoline hacking processing mould that faces down and keeps flat, then by existing technique matched moulds, sulfuration.
through testing:the method has solved former method in the time of the sulfuration of fetus dress mould, the fetus distortion causing due to formed precision and subsequent process, and the groove location that causes the dash offset plate sulfidization molding on position and the mould of adhesive tape produces deviation, cause sulfuration fetus dash offset plate place out to have starved, the problem of the defects such as exposed cord in tyre cavity.
advantage of the present invention is: the present invention mainly by before sulfuration in mould preset adhesive tape semi-finished product, by sulfuration in in-mold molding, fixing method.The method can effectively solve the problem that occurs the defect such as starved, exposed cord in tyre cavity after the one-sided aero tyre with ridge dash offset plate vulcanizes at dash offset plate position, has improved product quality.Prevent that dash offset plate from throwing off and getting rid of in the use procedure of tire, access times can improve more than 10 times, have improved the service life of tire, and the security performance of aircraft.

Detailed description of the invention
A manufacture method for the one-sided ridge dash offset plate of aero tyre, comprises the steps:
(1) tyre vulcanized mould is divided into upper and lower mould, first tire is vulcanized at counterdie with a side design of dash offset plate; Design the extrusion shape of the mouth as one speaks of dash offset plate according to designed dash offset plate shape, for carry out the extrusion of dash offset plate adhesive tape on extruder;
(2) by the sidewall of stereotyped fetus one side to tire shoulder position, and the binding face of dash offset plate adhesive tape and fetus, brushes gasoline the surface preparation with wire brush hacking, to remove surface impurity, interleaving agent etc., to ensure end product quality;
(3) by after the cutting of dash offset plate adhesive tape fixed length, be connected into a ring-type, and the processing of brush gasoline hacking is done in butt joint;
