Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Referring to figs. 1 to Fig. 3, the double countersunk head internally threaded rivets of a kind of Drawing-Core staking, including core pulling 1, rivet body 2 and ailhead 3；
It is characterized by: being provided with thin core 6 in the core pulling 1, breaking portion when breaking is served as, is provided on the rivet body 2 interior
Screw thread 5, the core pulling 1 and the intersection of ailhead 3 are provided with arc surface 7, for opening flange riveting side 4, thin 6 position of core
Corresponding with 5 position of internal screw thread, 7 size of arc surface is matched with 10 size of movement slots, and ailhead 3 is facilitated to enter movement slots
10, inclined-plane 8 is provided on the rivet body 2, for holding out against metal plate, the inclined-plane 8 is particularly located on rivet body 2 far from ailhead 3,
The core pulling 1 is located at the inside of rivet body 2, and 1 size of core pulling is matched with 2 internal diameter of rivet body, it is ensured that core pulling 1 can be just
Be inserted into rivet body 2 and will not Automatic-falling, be provided with movement slots 10 on the rivet body 2, flange riveting side be provided on the rivet body 2
4, positioning surface 9 is provided on the rivet body 2, for determining that ailhead 3 gos deep into the depth of rivet body 2.
10 size of movement slots is matched with 3 size of ailhead, grooving 11 is provided on flange riveting side 4, for protecting
Card core print 3 can go deep into movement slots 10, and for the positioning surface 9 between internal screw thread 5 and movement slots 10, the thin core 6 is specific
In core pulling 1 at internal screw thread 5, guarantee that core pulling 1 is broken preceding core pulling 1 and will not contact internal screw thread 5.
10 internal diameter of movement slots is less than the outer diameter of ailhead 3, and the movement slots 10 are located on rivet body 2 at ailhead 3, institute
It states grooving 11 and is located on flange riveting side 4 circumferentially array-like distribution, make 4 uniform force of flange riveting side.
The outer diameter of the ailhead 3 is matched with the outer diameter of rivet body 2, is provided with chamfering on flange riveting side 4, is facilitated core print
3 enter in movement slots 10.
The working principle of the utility model are as follows: will need to be put into spiral shell in the double countersunk heads of Drawing-Core staking between the metal plate riveted
Line rivet draws core pulling 1 with riveting gun, and by the pulling force of riveting gun, arc surface 7 is expressed on rivet body 2 ailhead 3 connecting with core pulling 1
Flange riveting side 4；Flange riveting side 4 makes because by powerful pulling force effect, ailhead 3 squeezes flange riveting side 4 and then squeezes into movement slots 10
Flange riveting side 4 is softened and swells, form a horn mouth；When ailhead 3 is expressed to the positioning surface 9 in rivet body 2, the flange
Riveting side 4 has strutted completely and flange fastening is in the bore edges of riveted plating, and the ailhead 3 cannot be squeezed into movement slots 10 at this time,
But the pulling force of rivet riveting gun is also continuing, and core pulling 1 is broken as at thin core 6 with ailhead 3 under the pulling force effect for continuing to increase
Only, the core pulling 1 of disconnection and ailhead 3 are detached from rivet body 2, and internal screw thread 5 is intact to be retained in riveting plate, and it is dynamic to complete all riveting installations
Make, work terminates.
The utility model is not confined to these for being further described to the utility model by above-described embodiment
Specific embodiment.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc.,
It is interpreted as being within the protection scope of the utility model.
