specific Embodiment approach 1

[0026] Specific Embodiment 1: In this embodiment, the titanium blind rivet sleeve for aerospace is composed of a plastic deformation part and a bearing part; the bearing part of the titanium blind rivet sleeve for aerospace is made of high-strength titanium alloy, and the plastic deformation part It is made of industrial pure titanium with alloy grades TA1~TA4 or titanium alloy with alloy grades TA5~TA10.

specific Embodiment approach 2

[0027] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the high-strength titanium alloy is a high-strength duplex titanium alloy with an alloy grade of TC3-TC23, a β-type titanium alloy with an alloy grade of TB2-TB10 or The alloy grade is near α-type titanium alloy of TA11~TA26. Others are the same as the first embodiment.

specific Embodiment approach 3

[0028] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that: the load-bearing parts of the titanium blind rivet sleeves for aerospace are discontinuously distributed along the axial direction. Others are the same as the first or second embodiment.

[0029] The plastic deformation part of the titanium blind rivet sleeve for aerospace can be designed between two load-bearing parts; N plastic deformation parts and N+1 load-bearing parts can also be designed according to special needs.

Abstract

A titanium blind rivet cover and a preparation method thereof, which relate to a blind rivet cover and a preparation method thereof. It solves the problem that my country's aerospace titanium blind rivets rely on imports for a long time, is expensive, and is controlled by others, and breaks the monopoly of very few manufacturers. The rivet set of titanium blind rivet for aerospace is composed of plastic deformation part and load-bearing part; the load-bearing part of titanium blind rivet rivet set for aerospace is made of high-strength titanium alloy, and the plastic deformation part is made of alloy grade TA1~TA4 It is made of industrial pure titanium or titanium alloy whose alloy grade is TA5~TA10. The preparation method: 1. Design the position and length of the plastic deformation part and the bearing part of the rivet sleeve according to requirements; 2. Calculate and weigh the material powder; 3. Lay flat; 4. Vacuum hot-press sintering. The invention is used for making titanium blind rivets for aerospace, and is used in 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...
