Description
The technical field is as follows:
the utility model relates to a rivet is cut, especially relates to a afterburning type rivet cutting nipper.
Background art:
in the riveting repair of aviation soldier's army, there is not specialized tool to shearing the rivet, and when shearing the rivet, repair personnel adopt other appurtenance such as flat tongs, hacksaw to carry out the rivet and cut, and the length of rivet rod can not accurate control, and there is burr, the quality poor in the rivet rod head surface.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: overcomes the defects of the prior art, and provides the stressing type rivet cutting pliers which is reasonable in design, can accurately control the length of a cutting rivet, saves labor and time.
The technical scheme of the utility model is that:
the stress-application rivet cutting pliers comprise a first shear blade and a second shear blade, wherein the upper ends of the first shear blade and the second shear blade are hinged and fixed through a connecting bolt, the upper ends of the first shear blade and the second shear blade are circular, through holes with different diameters are uniformly distributed along the circumference, and the through holes in the first shear blade correspond to the through holes in the second shear blade; the first shear blade is provided with a heightening gasket, the lower ends of the first shear blade and the second shear blade are respectively hinged with the upper parts of the two stressing handles, and the upper ends of the two stressing handles are hinged together.
The number of the heightening gaskets is more than two, the heightening gaskets are sleeved on the threaded rods of the connecting bolts through center holes and are fixed through pressing plate nuts, and each heightening gasket is 1mm in height.
The number of the through holes of the first shear blade is twelve, and the first shear blade is provided with 120-degree countersunk sockets of six rivets with different diameters for shearing the 120-degree rivets. And positioning columns are respectively arranged on the inner sides of the two stress application handles and are respectively inserted into two ends of the reset spring.
The utility model has the advantages that:
1. the utility model discloses an adjustment increases the gasket (the shear blade thickness is 6mm and increases gasket quantity in addition) and obtains required rivet shearing length, and control is accurate.
2. The utility model discloses a afterburning handle extension arm of force of a pair of shear blade, can be more relaxed cut the rivet, laborsaving saving time.
3. The utility model discloses can change the quantity that increases the gasket as required to adapt to different rivet heights, in addition, be provided with a plurality of perforating holes on a pair of shear blade respectively, can adapt to the shearing of different diameter rivets, enlarge application scope.
4. The utility model discloses 120 countersunk socket of different diameter rivets are still seted up to first shear blade for 120 the shearing of rivet, easily the implementation is promoted, has good economic benefits.
Description of the drawings:
FIG. 1 is a schematic structural view of a forced rivet cutting nipper;
FIG. 2 is a left side view of the reinforcement type rivet cutting pliers shown in FIG. 1;
fig. 3 is a top view of the force applying type rivet cutting pliers shown in fig. 1.
The specific implementation mode is as follows:
example (b): referring to fig. 1-3, in the figure, 1-a first shear blade, 2-a second shear blade, 3-a through hole, 4-a connecting bolt, 5-a forcing handle, 6-a heightening gasket, 7-a pressing sheet nut, 8-a positioning column and 9-a return spring.
Afterburning rivet cutting nipper includes first shear blade 1 and second shear blade 2, and the upper end of first shear blade 1 and second shear blade 2 is passed through connecting bolt 4 and is articulated fixed, wherein: the upper ends of the first shear blade 1 and the second shear blade 2 are circular, through holes 3 with different diameters are uniformly distributed along the circumference, and the through holes on the first shear blade 1 correspond to the through holes on the second shear blade 2; the first shear blade 1 is provided with a heightening gasket 6, the lower ends of the first shear blade 1 and the second shear blade 2 are respectively hinged with the upper parts of the two stressing handles 5, and the upper ends of the two stressing handles 5 are hinged together.
The preferred scheme is as follows: the number of the heightening gaskets 6 is more than two, and the heightening gaskets 6 are sleeved on the threaded rod of the connecting bolt 4 through a central hole and fixed through the pressing nut 7, and the height of each heightening gasket 6 is 1 mm. The number of the through holes 3 of the first shear blade 1 is twelve, and the first shear blade 1 is provided with 120-degree countersunk sockets (not shown in the figure) of six rivets with different diameters, and the 120-degree countersunk sockets are used for shearing the 120-degree rivets. The inner sides of the two stressing handles 5 are respectively provided with a positioning column 8, and the two positioning columns are respectively inserted into two ends of a return spring 9.
The use of the tool comprises the following steps:
1) placing the rivet into the through hole 3 with the corresponding diameter;
2) calculating the required rivet stem length;
3) adjusting the height increasing gaskets 6 (the thickness of the shear blades is 6mm plus the number of the height increasing gaskets) to obtain the required rivet shearing length, and locking the rivet shearing length by using the connecting bolts 4;
4) the force application handle 5 is held tightly, the first shear blade 1 and the second shear blade 2 are staggered, and the rivet is cut.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
