Rivet sleeve for titanium self-plugging rivet and preparation method of rivet sleeve

Abstract

The invention discloses a rivet sleeve for titanium self-plugging rivet and a preparation method of the rivet sleeve, and solves the problems that titanium self-plugging rivets for aerospace in China rely on imports for a long time, are high in cost and are controlled by others, and breaks through the monopoly of an individual manufacturer. The titanium self-plugging rivet for aerospace is composed of a plastic deformation part and a bearing part and is made from high-strength titanium alloy, and the plastic deformation part is made from industrial pure titanium of which an alloy designation is TA1-TA4 or the alloy designation is TA5-TA10. The preparation method comprises the following steps: firstly, designing the position and length of the plastic deformation part of the rivet and the bearing part as required; secondly, calculating and weighing material powder; thirdly, paving horizontally; and fourthly, hot pressed sintering in vacuum. The preparation method provided by the invention is used for manufacturing the titanium self-plugging rivets for aerospace which is used for the field of aerospace.

Description

technical field [0001] The invention relates to a blind rivet sleeve and a preparation method thereof. Background technique [0002] Titanium blind rivets are used in a very large amount in the aerospace field, but because there are only a few manufacturers in the world that can produce titanium blind rivets for the aerospace field, the market price is extremely expensive, each priced at 200 ~$300. my country's aerospace titanium blind rivets have always relied on imports, which not only costs a lot, but more seriously limits the development of my country's aerospace in key areas. [0003] After the blind rivet is inserted into the riveted object, the rivet mandrel is pulled out, so that the part of the rivet sleeve outside the riveted object is deformed, and the riveted object is fixed, thereby realizing riveting. The selection of titanium blind rivets can greatly reduce the weight of the connecting parts and increase the payload of aerospace vehicles, so titanium blind r...

Problems solved by technology

[0008] The present invention is to solve the problem that only a few manufacturers in the world can produce titanium blind rivets for aerospace use, forming technical monopoly and technical barriers. my country's titanium blind rivets for aerospace use have long relied on imports, are expensive, and are restricted by others. A kind of titanium blind rivet rivet sleeve for aerospace and preparation method thereof
