Abstract
The utility model belongs to the technical field of rivet assembly and relates to a blind rivet core bar separator. The blind rivet core bar separator is a cylindrical shaft, a ring-shaped limiting protrusion (2) is arranged in the position of the left end of the splitter and raises out of the cylindrical shaft, a spherical socket (4) is arranged on the right end surface of the splitter, the radius of the spherical socket is equal to the radius of the pin head of a blind rivet to be spitted, and a blind hole (3) is formed axially in the center of the spherical socket (4). With the blind rivet core bar separator, a user can remove the core bar from the blind rivet easily, therefore, the damage and the deformation of the parts are prevented, and the separation efficiency is improved.
Description
Technical field
The utility model belongs to the riveted joint mounting technology, relates to a kind of self-plugging rivet core bar decomposer.
Background technology
The self-plugging rivet is olation that the present world and domestic air mail industry generally adopt is: use bit drills to fall the core bar of part self-plugging rivet; Take out retaining ring; Wash out the rivet core bar; Bore rivet nail bar.The key of this process is the first step, bores the extremely difficult control of process of rivet core bar, is easy to cause run to bore be damaged to part, and decomposition efficiency is low.Particularly in the decomposable process of thin plate titanium alloy component, cause part to produce distortion easily when using punching pin to dash the nail bar, and then cause rivet hole to become overproof greatly.
Summary of the invention
The purpose of this utility model is: propose a kind of decomposer of being convenient to take out the self-plugging rivet core bar, to avoid injuring part and to cause part deformation, improve decomposition efficiency.
The technical solution of the utility model is: self-plugging rivet core bar decomposer, it is characterized in that, it is a cylinder axis, an annular stop boss that protrudes cylinder axis is arranged in the position near the decomposer left end, the left side of positive stop lug boss is the impact bar that cooperates with riveting gun, a spherical nest is arranged on the right side of decomposer, the radius of a ball of the self-plugging rivet ailhead that the radius of a ball of this sphere nest equals to be decomposed, an axial blind hole is arranged at the center of spherical nest, the aperture of this blind hole is greater than the diameter of the self-plugging rivet core bar that is decomposed, and the length of this blind hole is not less than 3mm.
The utility model has the advantages that: use the utility model can take out the core bar of self-plugging rivet easily, avoided injuring part and caused part deformation, improved decomposition efficiency.Evidence, decomposition efficiency of the present utility model have improved more than 3 times, have guaranteed the dismounting quality of self-plugging rivet effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below the utility model is described in further details.Referring to Fig. 1, self-plugging rivet core bar decomposer, it is characterized in that, it is a cylinder axis, an annular stop boss 2 that protrudes cylinder axis is arranged in the position near the decomposer left end, the left side of positive stop lug boss 2 is the impact bars 1 that cooperate with riveting gun, a spherical nest 4 is arranged on the right side of decomposer, the radius of a ball of the self-plugging rivet ailhead that the radius of a ball of this sphere nest equals to be decomposed, an axial blind hole 3 is arranged at the center of spherical nest 4, the aperture of this blind hole is greater than the diameter of the self-plugging rivet core bar that is decomposed, and the length of this blind hole is not less than 3mm.Using method of the present utility model is:
Select different decomposers and be installed on the riveting gun according to the diameter of self-plugging rivet.The ball-and-socket of decomposer partly is adjacent to the ailhead of self-plugging rivet, and opposite side uses baffle plate to withstand the rivet pier nose, starts riveting gun gently and impacts, and the rivet core bar will spill to the direction of blind hole 3.Retaining ring on the self-plugging rivet core bar is removed, used punching pin that the self-plugging rivet core bar is gone out then.Use the air drill branch to take off remaining rivet nail body at last.
