Abstract
The invention discloses a titanium alloy rivet, which comprises a rivet body and a guide pillar, wherein the rivet body and the guide pillar are made of a titanium alloy material; the surface of the rivet body and the surface of the guide pillar are respectively provided with a titanium nitride layer; the top of the rivet body is provided with a rivet cap; the bottom end of the rivet body is symmetrically provided with two grooves; and the guide pillar is in clearance fit with the grooves. Through the mode, according to the titanium alloy rivet disclosed by the invention, a flange structure is arranged on the rivet body and brings convenience for flanging treatment; the guide pillar is in clearance fit with the flanging structure, so that persons can be prevented from being damaged due to a sharp opening caused by flanging; and the surface of the titanium alloy rivet is provided with the titanium nitride layer, therefore hardness and bonding strength of the rivet are enhanced, and problem that the rivet is easy to break due to corrosion is solved.
Description
Technical field
The present invention relates to the specialty metal application, particularly relate to a kind of TITAIUM ALLOY RIVETS.
Background technique
The rivet kind is a lot, generally is used for the riveted joint occasion of nonmetallic material.
General rivet is easy discontinuity in the process that flange is handled, and causes flange inhomogeneous, thus the intensity of influence riveted joint, and also the sharp opening that flange produces causes damage to the staff easily.
General rivet adopts soft iron system to make, and iron is that material exists the easy oxidation and the problem of acid resistant alkali erosion not.So, cause rivet easy corrosion after long-term the use to be collapsed, thereby cause riveting intensity to reduce greatly, influence is normally used.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of TITAIUM ALLOY RIVETS, can handle to flange to bring convenience, and can strengthen the hardness and the adhesive strength of rivet, has solved the problem that the easy corrosion of rivet is collapsed.
For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: a kind of TITAIUM ALLOY RIVETS is provided, comprises: rivet body and directional post, and said rivet body and directional post adopt titanium alloy material; The surface of said rivet body and directional post is provided with titanium nitride layer; The top of said rivet body is provided with the rivet cap, and the bottom of said rivet body is symmetrically arranged with two grooves, Spielpassung between said directional post and the groove.
In preferred embodiment of the present invention, concentric co-axial setting between said directional post and the rivet body, the groove top is extended in the end of said directional post.
In preferred embodiment of the present invention, the surface of said directional post is provided with screw thread.
In preferred embodiment of the present invention, said titanium nitride layer forms through nitrogenize heat treatment.
In preferred embodiment of the present invention, the heat treated temperature of said nitrogenize is 600 ℃ ~ 800 ℃.
In preferred embodiment of the present invention, the hardness of said titanium nitride layer is 2500HV ~ 3500HV.
The invention has the beneficial effects as follows: TITAIUM ALLOY RIVETS rivet body of the present invention is provided with turnup structure, handles to flange and has brought convenience, and Spielpassung between directional post and the turnup structure guarantees that the sharp opening that causes because of flange can not cause damage to personnel; The TITAIUM ALLOY RIVETS surface is provided with titanium nitride layer, has strengthened the hardness and the adhesive strength of rivet, has solved the problem that the easy corrosion of rivet is collapsed.
Description of drawings
Fig. 1 is the structural representation of TITAIUM ALLOY RIVETS one preferred embodiment of the present invention;
The sectional view of Fig. 2 Fig. 1;
The mark of each parts is following in the accompanying drawing: 1, rivet body, 2, directional post, 3, the rivet cap, 4, groove, 5, titanium nitride layer, 6, screw thread.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 to Fig. 2, the embodiment of the invention comprises:
A kind of TITAIUM ALLOY RIVETS comprises: rivet body 1 and directional post 2.
The top of said rivet body 1 is provided with rivet cap 3, and the bottom of said rivet body 1 is symmetrically arranged with two grooves 4, Spielpassung between said directional post 2 and the groove 4.
In the TITAIUM ALLOY RIVETS of the present invention, two grooves 4 of rivet body 1 bottom are the turnup structure in the rivet work process, handle to flange and have brought convenience, guarantee that the rivet after flange is handled has good riveting intensity.
The surface of said directional post 2 is provided with screw thread 6, has brought facility on directional post 2, assembling fastening piece in the working procedure.
Said rivet body 1 adopts titanium alloy material with directional post 2, and the rivet body 1 that titanium alloy is processed and the surface of directional post 2 are provided with titanium nitride layer 5.
Said titanium nitride layer 5 forms through nitrogenize heat treatment, and the heat treated temperature of nitrogenize is 600 ℃ ~ 800 ℃, and the hardness of titanium nitride layer is 2500HV ~ 3500HV.
Titanium alloy material has corrosion resistant characteristic, and titanium alloy and titanium nitride layer 5 are combined, and guarantees that rivet has higher decay resistance and hardness, has strengthened the hardness and the adhesive strength of rivet simultaneously, has solved the problem that the easy corrosion of rivet is collapsed.
The beneficial effect of TITAIUM ALLOY RIVETS of the present invention is:
The TITAIUM ALLOY RIVETS surface is provided with titanium nitride layer 5, guarantees that rivet has higher decay resistance and hardness, has strengthened the hardness and the adhesive strength of rivet simultaneously, has solved the problem that the easy corrosion of rivet is collapsed.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
