Abstract
The utility model discloses a bimetal rivet, which structurally comprises a work section (1), wherein one end of the work section (1) is provided with a riveting head (2), and one end of the work section (1) is welded with a riveting section (3). The utility model improves the riveting connection strength and has the installation and riveting performance of an ordinary rivet through adopting materials in different intensities on the same rivet, the bimetal rivet is adopted for connection under the same stress condition, the dimension of the rivet can be greatly reduced for meeting the requirements of special positions, at the same time, the structural weight is reduced, and the utility model belongs to a novel fastening element capable of being popularized in the fields of aviation and aerospace, and has good economic benefits and social benefits.
Description
Technical field
The utility model relates to a kind of rivet, particularly relates to a kind of bimetal rivet.
Background technique
The many structures of Aero-Space industry connect needs to adopt the riveted joint mode, and these connection parts need higher join strength, the connection space structure is restricted simultaneously, can not infinitely strengthen the physical dimension of connection part, though conventional rivets has the riveted joint linkage function, can not satisfy the structural strength requirement.If adopt the rivet made from high-strength material fully, though satisfied the structure requirement of strength, the riveted joint performance is bad.
Summary of the invention
The purpose of this utility model is, a kind of bimetal rivet is provided.Can satisfy the structural strength requirement, have good riveted joint performance again.
The technical solution of the utility model: a kind of bimetal rivet, formation comprises active section, active section one end is provided with die, active section one end and riveting segment welding.
In the aforesaid bimetal rivet, described active section is made greater than the high-strength metal material of 1100Mpa with tensile strength.
In the aforesaid bimetal rivet, described riveting segment is made less than the low intensity metal material of 550MPa with tensile strength.
Compared with prior art, the utility model is by adopting the material of varying strength on same rivet, both improved the riveted joint join strength, have the installation and the riveted joint performance of conventional rivets again, under identical stressing conditions, adopt the bimetal rivet to connect, can reduce the rivet size greatly, to satisfy the spatial position requirement, alleviate structure weight simultaneously, the novel fastener in Aeronautics and Astronautics field meeting large-scale popularization has good economic benefit and social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-active section, 2-die, 3-riveting segment, 4-weld seam.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.The utility model as shown in Figure 1.A kind of bimetal rivet, formation comprises active section 1, active section 1 one ends are provided with die 2, active section 1 one ends and riveting segment 3 welding.Active section 1 usefulness tensile strength is made greater than the high-strength metal material of 1100Mpa.Riveting segment 3 usefulness tensile strength are made less than the low intensity metal material of 550MPa.
During concrete the making, adopt the metallic material of two kinds of varying strengths to make rivet, connect working portion and adopt high-strength metal material, to satisfy the join strength requirement, riveting portion adopts the low intensity metal material, and to satisfy the rivet performance requirement, high low-intensity material adopts welding manner to connect.Described high-strength metal material is that tensile strength reaches the above titanium alloy of 1100MPa after the heat treatment; Described low intensity metal material be after the annealing in process tensile strength less than the metallic material below the 550MPa; The die 2 of active section 1 is upset and is made shape, and the length of active section 1 is processed by different thickness of interlayer requirements, considers the welding surplus; Weld seam 4 between active section 1 and the riveting segment 3 adopts friction welding or electron-bombardment welding to connect in succession, and machining bar portion's cylindrical and tail end face are adopted in the welding back, guarantee that rivet meets the design size requirement.Also can select for use the alloy steel or stainless steel of varying strength to make the bimetal rivet.
Claims (3)
1. bimetal rivet is characterized in that: constitute and comprise active section (1), active section (1) one end is provided with die (2), and active section (1) one end welds with riveting segment (3).
2. according to the bimetal rivet shown in the claim 1, it is characterized in that: described active section (1) is made greater than the high-strength metal material of 1100Mpa with tensile strength.
3. according to the bimetal rivet shown in the claim 1, it is characterized in that: described riveting segment (3) is made less than the low intensity metal material of 550MPa with tensile strength.
