Abstract
The utility model discloses a closed conical pushing type plugging rivet which mainly comprises a rivet mandrel and a rivet shell. The rivet shell is in the shape of a cap with a closed end, the rivet mandrel comprises a rivet stem and a rivet head positioned at the upper end of the rivet stem, the rivet shell is closely wrapped on the rivet head of the rivet mandrel, and a conical surface is formed between the rivet head and the rivet stem of the rivet mandrel. The closed conical pushing type plugging rivet has the advantages that the closed conical pushing type plugging rivet is simple in structure and low in manufacturing cost, an auxiliary hole can be completely blocked after the closed conical pushing type plugging rivet is riveted and plugged in the auxiliary hole, the closed conical pushing type plugging rivet is firm and cannot fall off, and accordingly potential safety hazards of a component due to leakage of the auxiliary hole are effectively eradicated completely.
Description
Technical field
The utility model relates to the technical field of rivet, more particularly relates to the technical field of riveting plug rivet.
Background technique
For satisfying processing, measure, the arts demand of assembling is so-called in the hole that workpiece is set up to be auxiliary hole, the final needs that this auxiliary hole has stop up, as bent axle, piston, cylinder and engine cylinder-body, when these parts add the auxiliary hole that forms man-hour and need stop up, requirement to type of tamper evidence is just very high, mostly being the ball expanding greatly at the employed stemming method of these special occasions at present stops up, thread seal stops up and the double-screw bolt sealing is stopped up, when above-mentioned stemming method uses, at high temperature, high pressure or be subjected under the conditions such as judder, type of tamper evidence still has the possibility that comes off, and will bring serious potential safety hazard if blocked auxiliary hole generation leakage occurs.
The model utility content
The purpose of this utility model is exactly to provide a kind of obstruction firm, simple in structure in order to solve above-mentioned deficiency, low cost of manufacture, and enclosed type cone-shaped nail extrusion type riveting plug rivet easy to use.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Enclosed type cone-shaped nail extrusion type riveting plug rivet, it mainly is made of nail core and nail shell, described nail shell is the cap shape of end sealing, described nail core is made of nail bar and the ailhead that is positioned at nail bar upper end portion, the nail shell closely wraps up cover and puts on the ailhead of nail core, forms conical surface shape between the ailhead of described nail core and the nail bar.
The arranged outside of described nail shell the other end opening has chamfering.
Be positioned at ailhead one end on the nail bar of described nail core and be provided with fracture.
The conical surface that forms between described ailhead and the nail bar is outer cydariform.
The conical surface that forms between described ailhead and the nail bar is inner concave shape.
The ailhead integral body of described nail core is I-shaped.
The integral body of described nail shell is column.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, low cost of manufacture, adopt the method for riveting plug to carry out the obstruction of auxiliary hole, under the cooperation of special-purpose riveting plug rifle, use very convenient, after the riveting plug is finished, the nail shell can be blocked in the auxiliary hole together with the ailhead of nail core, form sealed condition completely, form very tight squeezed state at nail shell and the contacted ring-side wall of auxiliary hole again, its obstruction form is compared more firm with present stemming method, can not produce obscission, stop the potential safety hazard that parts bring owing to the leakage of auxiliary hole well.
